112-537: Xcas is a user interface to Giac , which is an open source computer algebra system (CAS) for Windows , macOS and Linux among many other platforms. Xcas is written in C++ . Giac can be used directly inside software written in C++. Xcas has compatibility modes with many popular algebra systems like WolframAlpha , Mathematica , Maple , or MuPAD . Users can use Giac/Xcas to develop formal algorithms or use it in other software. Giac
224-454: A stimulus . This is based on the notion that a defensive reflex to a stimulus such as withdrawal or escape becomes stronger after the exposure to a different harmful or threatening stimulus. An everyday example of this mechanism is the repeated tonic stimulation of peripheral nerves that occurs if a person rubs their arm continuously. After a while, this stimulation creates a warm sensation that can eventually turn painful. This pain results from
336-406: A Pathways to Enable Open-Source Ecosystems (POSE) program to support open source innovation. The adoption of open-source software by industry is increasing over time. OSS is popular in several industries such as telecommunications , aerospace , healthcare , and media & entertainment due to the benefits it provides. Adoption of OSS is more likely in larger organizations and is dependent on
448-550: A bond if the object makes sounds. Play generally describes behavior with no particular end in itself, but that improves performance in similar future situations. This is seen in a wide variety of vertebrates besides humans, but is mostly limited to mammals and birds . Cats are known to play with a ball of string when young, which gives them experience with catching prey. Besides inanimate objects, animals may play with other members of their own species or other animals, such as orcas playing with seals they have caught. Play involves
560-541: A bug needs to be fixed in their project. This is established by communicating with the OSS community through avenues such as bug reporting and tracking or mailing lists and project pages. Next, OSS developers select or are assigned to a task and identify a solution. Because there are often many different possible routes for solutions in OSS, the best solution must be chosen with careful consideration and sometimes even peer feedback . The developer then begins to develop and commit

Transfer of learning is the application of skill, knowledge or understanding to resolve a novel problem or situation that happens when certain conditions are fulfilled. Research indicates that learning transfer
784-524: A child over time. Studies within metacognition have proven the value in active learning, claiming that the learning is usually at a stronger level as a result. In addition, learners have more incentive to learn when they have control over not only how they learn but also what they learn. Active learning is a key characteristic of student-centered learning . Conversely, passive learning and direct instruction are characteristics of teacher-centered learning (or traditional education ). Associative learning
896-431: A condition called learned helplessness . There is evidence for human behavioral learning prenatally , in which habituation has been observed as early as 32 weeks into gestation , indicating that the central nervous system is sufficiently developed and primed for learning and memory to occur very early on in development . Play has been approached by several theorists as a form of learning. Children experiment with
1008-509: A consequence of ongoing interactions between people and their environment. The nature and processes involved in learning are studied in many established fields (including educational psychology , neuropsychology , experimental psychology , cognitive sciences , and pedagogy ), as well as emerging fields of knowledge (e.g. with a shared interest in the topic of learning from safety events such as incidents/accidents , or in collaborative learning health systems ). Research in such fields has led to
1120-507: A copy of the license is provided to recipients with the code. One important legal precedent for open-source software was created in 2008, when the Jacobson v Katzer case enforced terms of the Artistic license , including attribution and identification of modifications. The ruling of this case cemented enforcement under copyright law when the conditions of the license were not followed. Because of
1232-453: A dog might learn to sit as the trainer scratches his ears, which ultimately is removing his itches (undesirable aspect). Positive reinforcement is defined by adding a desirable aspect of life or thing. For example, a dog might learn to sit if he receives a treat. In this example the treat was added to the dog's life. The typical paradigm for classical conditioning involves repeatedly pairing an unconditioned stimulus (which unfailingly evokes
SECTION 10
#17330847284931344-685: A form of learning is central to a child's learning and development. Through play, children learn social skills such as sharing and collaboration. Children develop emotional skills such as learning to deal with the emotion of anger, through play activities. As a form of learning, play also facilitates the development of thinking and language skills in children. There are five types of play: These five types of play are often intersecting. All types of play generate thinking and problem-solving skills in children. Children learn to think creatively when they learn through play. Specific activities involved in each type of play change over time as humans progress through
1456-409: A learner interacts with the e-learning environment, it is called augmented learning . By adapting to the needs of individuals, the context-driven instruction can be dynamically tailored to the learner's natural environment. Augmented digital content may include text, images, video, audio (music and voice). By personalizing instruction, augmented learning has been shown to improve learning performance for
1568-424: A lifetime. See also minimally invasive education . Moore (1989) purported that three core types of interaction are necessary for quality, effective online learning: In his theory of transactional distance, Moore (1993) contented that structure and interaction or dialogue bridge the gap in understanding and communication that is created by geographical distances (known as transactional distance). Rote learning
1680-548: A long history; researchers in the early 20th century described the possibility that "...habits or mental acts developed by a particular kind of training may inhibit rather than facilitate other mental activities". Finally, Schwarz, Bransford and Sears (2005) have proposed that transferring knowledge into a situation may differ from transferring knowledge out to a situation as a means to reconcile findings that transfer may both be frequent and challenging to promote. A significant and long research history has also attempted to explicate
1792-441: A low rate as well as for the weak and strong stimuli, respectively. Habituation has been shown in essentially every species of animal, as well as the sensitive plant Mimosa pudica and the large protozoan Stentor coeruleus . This concept acts in direct opposition to sensitization. Sensitization is an example of non-associative learning in which the progressive amplification of a response follows repeated administrations of
1904-454: A new bug. Early releases : The first version of the software should be released as early as possible so as to increase one's chances of finding co-developers early. Frequent integration: Code changes should be integrated (merged into a shared code base) as often as possible so as to avoid the overhead of fixing a large number of bugs at the end of the project life cycle. Some open-source projects have nightly builds where integration
2016-446: A product of social interaction and active involvement in both online and onsite courses. Research implies that some un-assessed aspects of onsite and online learning challenge the equivalency of education between the two modalities. Both onsite and online learning have distinct advantages with traditional on-campus students experiencing higher degrees of incidental learning in three times as many areas as online students. Additional research
2128-696: A progressively amplified synaptic response of the peripheral nerves. This sends a warning that the stimulation is harmful. Sensitization is thought to underlie both adaptive as well as maladaptive learning processes in the organism. Active learning occurs when a person takes control of his/her learning experience. Since understanding information is the key aspect of learning, it is important for learners to recognize what they understand and what they do not. By doing so, they can monitor their own mastery of subjects. Active learning encourages learners to have an internal dialogue in which they verbalize understandings. This and other meta-cognitive strategies can be taught to
2240-508: A public good as it is available to everyone and does not decrease in value for others when downloaded by one person. Open source software is unique in that it becomes more valuable as it is used and contributed to, instead of diminishing the resource. This is explained by concepts such as investment in reputation and network effects . The economic model of open-source software can be explained as developers contribute work to projects, creating public benefits. Developers choose projects based on
2352-438: A real predator. Soon the birds react less, showing habituation. If another stuffed owl is introduced (or the same one removed and re-introduced), the birds react to it again as though it were a predator, demonstrating that it is only a very specific stimulus that is habituated to (namely, one particular unmoving owl in one place). The habituation process is faster for stimuli that occur at a high rather than for stimuli that occur at
SECTION 20
#17330847284932464-456: A reflexive response) with another previously neutral stimulus (which does not normally evoke the response). Following conditioning, the response occurs both to the unconditioned stimulus and to the other, unrelated stimulus (now referred to as the "conditioned stimulus"). The response to the conditioned stimulus is termed a conditioned response . The classic example is Ivan Pavlov and his dogs. Pavlov fed his dogs meat powder, which naturally made
2576-526: A result of an event. For example, a fear of dogs that follows being bitten by a dog is episodic learning. Episodic learning is so named because events are recorded into episodic memory , which is one of the three forms of explicit learning and retrieval, along with perceptual memory and semantic memory . Episodic memory remembers events and history that are embedded in experience and this is distinguished from semantic memory, which attempts to extract facts out of their experiential context or – as some describe –
2688-472: A significant cost to animals, such as increased vulnerability to predators and the risk of injury and possibly infection . It also consumes energy , so there must be significant benefits associated with play for it to have evolved. Play is generally seen in younger animals, suggesting a link with learning. However, it may also have other benefits not associated directly with learning, for example improving physical fitness . Play, as it pertains to humans as
2800-447: A similar way user scripts and custom style sheets allow for web sites, and eventually publish the modification as a fork for users with similar preferences, and directly submit possible improvements as pull requests . The Open Source Initiative 's (OSI) definition is recognized by several governments internationally as the standard or de facto definition. OSI uses The Open Source Definition to determine whether it considers
2912-592: A software license open source. The definition was based on the Debian Free Software Guidelines , written and adapted primarily by Perens . Perens did not base his writing on the "four freedoms" from the Free Software Foundation (FSF), which were only widely available later. Under Perens' definition, open source is a broad software license that makes source code available to the general public with relaxed or non-existent restrictions on
3024-419: A stimulus diminishes when the stimulus is repeated. Thus, habituation must be distinguished from extinction , which is an associative process. In operant extinction, for example, a response declines because it is no longer followed by a reward. An example of habituation can be seen in small song birds—if a stuffed owl (or similar predator ) is put into the cage, the birds initially react to it as though it were
3136-522: A timeless organization of knowledge. For instance, if a person remembers the Grand Canyon from a recent visit, it is an episodic memory. He would use semantic memory to answer someone who would ask him information such as where the Grand Canyon is. A study revealed that humans are very accurate in the recognition of episodic memory even without deliberate intention to memorize it. This is said to indicate
3248-484: A very large storage capacity of the brain for things that people pay attention to. Multimedia learning is where a person uses both auditory and visual stimuli to learn information. This type of learning relies on dual-coding theory . Electronic learning or e-learning is computer-enhanced learning. A specific and always more diffused e-learning is mobile learning (m-learning), which uses different mobile telecommunication equipment, such as cellular phones . When
3360-422: A victory for OSS supporters. In open-source communities, instead of owning the software produced, the producer owns the development of the evolving software. In this way, the future of the software is open, making ownership or intellectual property difficult within OSS. Licensing and branding can prevent others from stealing it, preserving its status as a public good . Open source software can be considered
3472-443: Is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration , meaning any capable user is able to participate online in development, making

3584-415: Is memorizing information so that it can be recalled by the learner exactly the way it was read or heard. The major technique used for rote learning is learning by repetition , based on the idea that a learner can recall the material exactly (but not its meaning) if the information is repeatedly processed. Rote learning is used in diverse areas, from mathematics to music to religion. Meaningful learning
3696-404: Is a good or service, what can be considered a modification, governance through contract vs license, ownership and right of use. While there have been developments on these issues, they often lead to even more questions. The existence of these uncertainties in regulation has a negative impact on industries involved in technologies as a whole. Within the legal history of software as a whole, there
3808-477: Is a kind of learning occurring at a particular life stage that is rapid and apparently independent of the consequences of behavior. In filial imprinting, young animals, particularly birds, form an association with another individual or in some cases, an object, that they respond to as they would to a parent. In 1935, the Austrian Zoologist Konrad Lorenz discovered that certain birds follow and form
3920-450: Is a type of learning based on dialogue. In incidental teaching learning is not planned by the instructor or the student, it occurs as a byproduct of another activity — an experience, observation, self-reflection, interaction, unique event (e.g. in response to incidents/accidents), or common routine task. This learning happens in addition to or apart from the instructor's plans and the student's expectations. An example of incidental teaching
4032-495: Is able to do: Example Xcas commands: Xcas and Giac are open-source projects developed and written by Bernard Parisse [ fr ] and Renée De Graeve at the former Joseph Fourier University of Grenoble (now the Grenoble Alpes University ), France since 2000. Xcas and Giac are based on experiences gained with Parisse's former project Erable . Pocket CAS and CAS Calc P11 utilize Giac. The system
4144-539: Is absolutely another terrific way that individuals and organizations choose to contribute to open source projects. Groups like Open Collective provide a means for individuals to contribute monthly to supporting their favorite projects. Organizations like the Sovereign Tech Fund is able to contribute to millions to supporting the tools the German Government uses. The National Science Foundation established
4256-646: Is always related to semiosis , and is often associated with representational systems/activity. There are various functional categorizations of memory which have developed. Some memory researchers distinguish memory based on the relationship between the stimuli involved (associative vs non-associative) or based to whether the content can be communicated through language (declarative/explicit vs procedural/implicit). Some of these categories can, in turn, be parsed into sub-types. For instance, declarative memory comprises both episodic and semantic memory. Non-associative learning refers to "a relatively permanent change in
4368-459: Is called for to investigate the implications of these findings both conceptually and pedagogically. Benjamin Bloom has suggested three domains of learning in his taxonomy which are: These domains are not mutually exclusive. For example, in learning to play chess , the person must learn the rules (cognitive domain)—but must also learn how to set up the chess pieces and how to properly hold and move
4480-544: Is done automatically . Several versions: There should be at least two versions of the software. There should be a buggier version with more features and a more stable version with fewer features. The buggy version (also called the development version) is for users who want the immediate use of the latest features and are willing to accept the risk of using code that is not yet thoroughly tested. The users can then act as co-developers, reporting bugs and providing bug fixes. High modularization: The general structure of

Over the history of its discourse, various hypotheses and definitions have been advanced. First, it is speculated that different types of transfer exist, including: near transfer, the application of skill to solve a novel problem in a similar context; and far transfer,

4704-404: Is innovative since open-source programs are the product of collaboration among a large number of different programmers. The mix of divergent perspectives, corporate objectives, and personal goals speeds up innovation. Moreover, free software can be developed in accordance with purely technical requirements. It does not require thinking about commercial pressure that often degrades the quality of
4816-560: Is legal variety in this definition. Some jurisdictions attempt to expand or reduce this conceptualization for their own purposes. For example, The European Court of Justice defines a computer program as not including the functionality of a program, the programing language , or the format of data files. By limiting protections of the different aspects of software, the law favors an open-source approach to software use. The US especially has an open approach to software, with most open-source licenses originating there. However, this has increased
4928-558: Is possessed by humans , non-human animals , and some machines ; there is also evidence for some kind of learning in certain plants . Some learning is immediate, induced by a single event (e.g. being burned by a hot stove ), but much skill and knowledge accumulate from repeated experiences. The changes induced by learning often last a lifetime, and it is hard to distinguish learned material that seems to be "lost" from that which cannot be retrieved. Human learning starts at birth (it might even start before ) and continues until death as
5040-399: Is the concept that learned knowledge (e.g., a fact) is fully understood to the extent that it relates to other knowledge. To this end, meaningful learning contrasts with rote learning in which information is acquired without regard to understanding. Meaningful learning, on the other hand, implies there is a comprehensive knowledge of the context of the facts learned. Evidence-based learning
5152-417: Is the process by which a person or animal learns an association between two stimuli or events. In classical conditioning , a previously neutral stimulus is repeatedly paired with a reflex-eliciting stimulus until eventually the neutral stimulus elicits a response on its own. In operant conditioning, a behavior that is reinforced or punished in the presence of a stimulus becomes more or less likely to occur in
5264-552: Is the process by which people self-educate if a topic is exposed to them in a context that they already enjoy. For example, after playing a music-based video game, some people may be motivated to learn how to play a real instrument, or after watching a TV show that references Faust and Lovecraft, some people may be inspired to read the original work. Self-education can be improved with systematization. According to experts in natural learning, self-oriented learning training has proven an effective tool for assisting independent learners with
5376-440: Is the small and ideal period of time between the subject performing the desired behavior, and receiving the positive reinforcement as a result of their performance. The reward needs to be given immediately after the completion of the wanted behavior. Operant conditioning is different from classical conditioning in that it shapes behavior not solely on bodily reflexes that occur naturally to a specific stimulus, but rather focuses on
5488-412: Is the use of evidence from well designed scientific studies to accelerate learning. Evidence-based learning methods such as spaced repetition can increase the rate at which a student learns. Formal learning is a deliberate way attaining of knowledge, which takes place within a teacher-student environment, such as in a school system or work environment. The term formal learning has nothing to do with
5600-468: Is theoretically challenging in economic models, it is explainable as a sustainable social activity that requires resources. These resources include time, money, technology and contributions. Many developers have used technology funded by organizations such as universities and governments, though these same organizations benefit from the work done by OSS. As OSS grows, hybrid systems containing OSS and proprietary systems are becoming more common. Throughout
5712-505: Is used in SageMath for calculus operations. Among other things, Xcas can solve equations (Figure 3) and differential equations (Figure 4) and draw graphs . There is a forum for questions about Xcas. CmathOOoCAS , an OpenOffice.org plugin which allows formal calculation in Calc spreadsheet and Writer word processing, uses Giac to perform calculations. Here is a brief overview of what Xcas

#17330847284935824-412: Is when an aversive aspect of life or thing is added to the subject, for this reason it is called positive punishment. For example, the parent spanking their child would be considered a positive punishment, because a spanking was added to the child. Negative punishment is considered the removal of something loved or desirable from the subject. For example, when a parent puts his child in time out, in reality,
5936-491: Is when the instructor places a train set on top of a cabinet. If the child points or walks towards the cabinet, the instructor prompts the student to say "train". Once the student says "train", he gets access to the train set. Here are some steps most commonly used in incidental teaching: Incidental learning is an occurrence that is not generally accounted for using the traditional methods of instructional objectives and outcomes assessment. This type of learning occurs in part as
6048-604: The Civilization games are presented as an example – by using these modules gamers can dig deeper for knowledge about historical events in the gameplay. The importance of rules that regulate learning modules and game experience is discussed by Moreno, C., in a case study about the mobile game Kiwaka . In this game, developed by Landka in collaboration with ESA and ESO , progress is rewarded with educational content, as opposed to traditional education games where learning activities are rewarded with gameplay. Dialogic learning
6160-477: The University of New Mexico . Xcas is used in particular for learning algebra. There is a port of Giac/Xcas for Casio graphing calculators : fx-CG10, fx-CG20, fx-CG50, fx-9750GIII, fx-9860GIII, called χCAS (KhiCAS) . These calculators do not have their own computer algebra system . It is also available for TI Nspire CX, CX-II , and Numworks N0110 Open-source software Open-source software ( OSS )
6272-889: The distributed version control system (DVCS) are examples of tools, often open source, that help manage the source code files and the changes to those files for a software project in order to foster collaboration. CVCS are centralized with a central repository while DVCS are decentralized and have a local repository for every user. concurrent versions system (CVS) and later Subversion (SVN) and Git are examples of CVCS. The repositories are hosted and published on source-code-hosting facilities such as GitHub . Open-source projects use utilities such as issue trackers to organize open-source software development. Commonly used bug trackers include Bugzilla and Redmine . Tools such as mailing lists and IRC provide means of coordination and discussion of bugs among developers. Project web pages, wiki pages, roadmap lists and newsgroups allow for
6384-458: The Bazaar , open-source influential contributor Eric S. Raymond suggests a model for developing OSS known as the bazaar model. Raymond likens the development of software by traditional methodologies to building a cathedral, with careful isolated work by individuals or small groups. He suggests that all software should be developed using the bazaar style, with differing agendas and approaches. In
6496-630: The Public Interest . Within Europe some notable organizations are Free Software Foundation Europe , open-source projects EU (OSP) and OpenForum Europe (OFE). One Australian organization is Linux Australia while Asia has Open source Asia and FOSSAsia . Free and open source software for Africa (FOSSFA) and OpenAfrica are African organizations and Central and South Asia has such organizations as FLISOL and GRUP de usuarios de software libre Peru . Outside of these, many more organizations dedicated to
6608-569: The United States has focused on national security in regard to open-source software implementation due to the perceived threat of the increase of open-source software activity in countries like China and Russia, with the Department of Defense considering multiple criteria for using OSS. These criteria include: if it comes from and is maintained by trusted sources, whether it will continue to be maintained, if there are dependencies on sub-components in
6720-473: The advancement of open-source software exist. FOSS products are generally licensed under two types of licenses: permissive licensing and copyleft licensing . Both of these types of licenses are different than proprietary licensing in that they can allow more users access to the software and allow for the creation of derivative works as specified by the terms of the specific license, as each license has its own rules. Permissive licenses allow recipients of
6832-400: The application of skill to solve a novel problem presented in a different context. Furthermore, Perkins and Salomon (1992) suggest that positive transfer in cases when learning supports novel problem solving, and negative transfer occurs when prior learning inhibits performance on highly correlated tasks, such as second or third-language learning. Concepts of positive and negative transfer have

#17330847284936944-402: The bazaar model should exhibit the following patterns: Users should be treated as co-developers: The users are treated like co-developers and so they should have access to the source code of the software. Furthermore, users are encouraged to submit additions to the software, code fixes for the software, bug reports , documentation, etc. Having more co-developers increases the rate at which
7056-451: The child is losing the opportunity to be with friends, or to enjoy the freedom to do as he pleases. In this example, negative punishment is the removal of the child's desired rights to play with his friends etc. Reinforcement on the other hand is used to increase a wanted behavior either through negative reinforcement or positive reinforcement. Negative reinforcement is defined by removing an undesirable aspect of life, or thing. For example,

The collaborative and helpful behaviors exhibited by Mexican and Mexican-heritage children is a cultural practice known as being "acomedido". Chillihuani girls in Peru described themselves as weaving constantly, following behavior shown by the other adults. Episodic learning is a change in behavior that occurs as

Once the leadership and community are satisfied with the whole project, it can be partially released and user instruction can be documented. If the project is ready to be released, it is frozen, with only serious bug fixes or security repairs occurring. Finally,
7392-427: The company's IT usage, operating efficiencies, and the productivity of employees. Industries are likely to use OSS due to back-office functionality, sales support, research and development, software features, quick deployment, portability across platforms and avoidance of commercial license management. Additionally, lower cost for hardware and ownership are also important benefits. Organizations that contribute to
7504-471: The culture. This is different from acculturation , where a person adopts the values and societal rules of a culture different from their native one. Multiple examples of enculturation can be found cross-culturally. Collaborative practices in the Mazahua people have shown that participation in everyday interaction and later learning activities contributed to enculturation rooted in nonverbal social experience. As

As listed by a former vice president of the Open Source Initiative , some American organizations include the Free Software Foundation , Software Freedom Conservancy , the Open Source Initiative and Software in
7728-461: The distribution of project information that focuses on end users. The basic roles OSS participants can fall into multiple categories, beginning with leadership at the center of the project who have control over its execution. Next are the core contributors with a great deal of experience and authority in the project who may guide the other contributors. Non-core contributors have less experience and authority, but regularly contribute and are vital to
7840-401: The dogs learned that the bell signaled that food was about to come, and began to salivate when they heard the bell. Once this occurred, the bell became the conditioned stimulus (CS) and the salivation to the bell became the conditioned response (CR). Classical conditioning has been demonstrated in many species. For example, it is seen in honeybees, in the proboscis extension reflex paradigm. It
7952-428: The dogs salivate—salivating is a reflexive response to the meat powder. Meat powder is the unconditioned stimulus (US) and the salivation is the unconditioned response (UR). Pavlov rang a bell before presenting the meat powder. The first time Pavlov rang the bell, the neutral stimulus, the dogs did not salivate, but once he put the meat powder in their mouths they began to salivate. After numerous pairings of bell and food,
8064-601: The focus on patent rights within these licenses, which has seen backlash from the OSS community, who prefer other forms of IP protection. Another issue includes technological protection measures (TPM) and digital rights management (DRM) techniques which were internationally legally recognized and protected in the 1996 World Intellectual Property Organization (WIPO) Treaty . Open source software proponents disliked these technologies as they constrained end-users potentially beyond copyright law. Europe responded to such complaints by putting TPM under legal controls, representing

They may be given time to assist international youth workshops and training courses, on the condition they prepare, contribute, share, and can prove this offered valuable new insight, helped to acquire new skills, a place to get experience in organizing, teaching , etc. To learn a skill, such as solving a Rubik's Cube quickly, several factors come into play at once: Tangential learning
8288-533: The formality of the learning, but rather the way it is directed and organized. In formal learning, the learning or training departments set out the goals and objectives of the learning and oftentimes learners will be awarded with a diploma, or a type of formal recognition. Non-formal learning is organized learning outside the formal learning system. For example, learning by coming together with people with similar interests and exchanging viewpoints, in clubs or in (international) youth organizations, and workshops. From
8400-407: The identification of various sorts of learning. For example, learning may occur as a result of habituation , or classical conditioning , operant conditioning or as a result of more complex activities such as play , seen only in relatively intelligent animals. Learning may occur consciously or without conscious awareness. Learning that an aversive event cannot be avoided or escaped may result in
8512-537: The learner ponders his or her situation. This type of learning does not require a professor of any kind, and learning outcomes are unforeseen following the learning experience. Informal learning is self-directed and because it focuses on day-to-day situations, the value of informal learning can be considered high. As a result, information retrieved from informal learning experiences will likely be applicable to daily life. Children with informal learning can at times yield stronger support than subjects with formal learning in
8624-454: The learner's perspective, informal learning can become purposeful, because the learner chooses which rate is appropriate to learn and because this type of learning tends to take place within smaller groups or by oneself. The educational system may use a combination of formal, informal, and nonformal learning methods. The UN and EU recognize these different forms of learning (cf. links below). In some schools, students can get points that count in
8736-437: The learning of emotion through classical conditioning principles. Observational learning is learning that occurs through observing the behavior of others. It is a form of social learning which takes various forms, based on various processes. In humans, this form of learning seems to not need reinforcement to occur, but instead, requires a social model such as a parent, sibling, friend, or teacher with surroundings. Imprinting

Enculturation is the process by which people learn values and behaviors that are appropriate or necessary in their surrounding culture . Parents, other adults, and peers shape the individual's understanding of these values. If successful, enculturation results in competence in the language, values, and rituals of
8960-480: The many benefits provided, a huge issue to be considered is cybersecurity . While accidental vulnerabilities are possible, so are attacks by outside agents. Because of these fears, governmental interest in contributing to the governance of software has become more prominent. However, these are the broad strokes of the issue, with each country having their own specific politicized interactions with open-source software and their goals for its implementation. For example,
9072-560: The mid 2000s, more and more tech companies have begun to use OSS. For example, Dell's move of selling computers with GNU/Linux already installed. Microsoft itself has launched a Linux-based operating system despite previous animosity with the OSS movement. Despite these developments, these companies tend to only use OSS for certain purposes, leading to worries that OSS is being taken advantage of by corporations and not given anything in return. While many governments are interested in implementing and promoting open-source software due to
9184-406: The natural phases of learning. Extra Credits writer and game designer James Portnow was the first to suggest games as a potential venue for "tangential learning". Mozelius et al. points out that intrinsic integration of learning content seems to be a crucial design factor, and that games that include modules for further self-studies tend to present good results. The built-in encyclopedias in
9296-505: The number of people employed in the IT sector. OSS can be highly reliable when it has thousands of independent programmers testing and fixing bugs of the software. Open source is not dependent on the company or author that originally created it. Even if the company fails, the code continues to exist and be developed by its users. OSS is flexible because modular systems allow programmers to build custom interfaces, or add new abilities to it and it
9408-537: The number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $ 8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and allows capable end users to adapt software to their personal needs in
9520-457: The organizer's point of reference, non-formal learning does not always need a main objective or learning outcome. From the learner's point of view, non-formal learning, although not focused on outcomes, often results in an intentional learning opportunity. Informal learning is less structured than "non-formal learning". It may occur through the experience of day-to-day situations (for example, one would learn to look ahead while walking because of
9632-435: The perceived benefits or costs, such as improved reputation or value of the project. The motivations of developers can come from many different places and reasons, but the important takeaway is that money is not the only or even most important incentivization . Because economic theory mainly focuses on the consumption of scarce resources, the OSS dynamic can be hard to understand. In OSS, producers become consumers by reaping
9744-485: The possible dangers inherent in not paying attention to where one is going). It is learning from life, during a meal at the table with parents, during play , and while exploring etc.. For the learner, informal learning is most often an experience of happenstance, and not a deliberately planned experience. Thus this does not require enrollment into any class. Unlike formal learning, informal learning typically does not lead to accreditation. Informal learning begins to unfold as
9856-404: The potential to quicken innovation and create of social value. In France for instance, a policy that incentivized government to favor free open-source software increased to nearly 600,000 OSS contributions per year, generating social value by increasing the quantity and quality of open-source software. This policy also led to an estimated increase of up to 18% of tech startups and a 14% increase in
9968-404: The presence of that stimulus. Operant conditioning is a way in which behavior can be shaped or modified according to the desires of the trainer or head individual. Operant conditioning uses the thought that living things seek pleasure and avoid pain, and that an animal or human can learn through receiving either reward or punishment at a specific time called trace conditioning. Trace conditioning
10080-574: The project is fully released and only changed through minor bug fixes. Open source implementation of a standard can increase adoption of that standard. This creates developer loyalty as developers feel empowered and have a sense of ownership of the end product. Moreover, lower costs of marketing and logistical services are needed for OSS. OSS can be a tool to promote a company's image, including its commercial products. The OSS development approach has helped produce reliable, high quality software quickly and inexpensively. Open source development offers
10192-759: The project's development. New contributors are the least experienced but with mentorship and guidance can become regular contributors. Some possible ways of contributing to open-source software include such roles as programming , user interface design and testing, web design , bug triage , accessibility design and testing, UX design , code testing, and security review and testing. However, there are several ways of contributing to OSS projects even without coding skills. For example, some less technical ways of participating are documentation writing and editing, translation , project management , event organization and coordination, marketing, release management, community management, and public relations and outreach. Funding
10304-431: The rewards of contributing to a project. For example, a developer becomes well regarded by their peers for a successful contribution to an OSS project. The social benefits and interactions of OSS are difficult to account for in economic models as well. Furthermore, the innovation of technology creates constantly changing value discussions and outlooks, making economic model unable to predict social behavior. Although OSS
10416-490: The same license while weak copyleft licenses require the use of the same license only under certain conditions. Examples of this type of license include the GNU family of licenses , and the MPL and EPL licenses. The similarities between these two categories of licensing include that they provide a broad grant of copyright rights, require that recipients preserve copyright notices, and that
10528-583: The shaping of wanted behavior that requires conscious thought, and ultimately requires learning. Punishment and reinforcement are the two principal ways in which operant conditioning occurs. Punishment is used to reduce unwanted behavior, and ultimately (from the learner's perspective) leads to avoidance of the punishment, not necessarily avoidance of the unwanted behavior. Punishment is not an appropriate way to increase wanted behavior for animals or humans. Punishment can be divided into two subcategories, positive punishment and negative punishment. Positive punishment
10640-500: The similarity of the Artistic license to other open-source software licenses, the ruling created a precedent that applied widely. Examples of free-software license / open-source licenses include Apache licenses , BSD licenses , GNU General Public Licenses , GNU Lesser General Public License , MIT License , Eclipse Public License and Mozilla Public License . Several gray areas exist within software regulation that have great impact on open-source software, such as if software
10752-485: The software "in any manner they see fit, without requiring that they pay the author(s) of the software a royalty or fee for engaging in the listed activities." Despite initially accepting it, Richard Stallman of the FSF now flatly opposes the term "Open Source" being applied to what they refer to as "free software". Although he agrees that the two terms describe "almost the same category of software", Stallman considers equating
10864-401: The software evolves. Linus's law states that given enough eyeballs all bugs are shallow. This means that if many users view the source code, they will eventually find all bugs and suggest how to fix them. Some users have advanced programming skills, and furthermore, each user's machine provides an additional testing environment. This new testing environment offers the ability to find and fix
10976-484: The software should be modular allowing for parallel development on independent components. Dynamic decision-making structure: There is a need for a decision-making structure, whether formal or informal, that makes strategic decisions depending on changing user requirements and other factors. Compare with extreme programming . The process of Open source development begins with a requirements elicitation where developers consider if they should add new features or if
11088-453: The software to implement the author's copyright rights without having to use the same license for distribution. Examples of this type of license include the BSD , MIT , and Apache licenses . Copyleft licenses are different in that they require recipients to use the same license for at least some parts of the distribution of their works. Strong copyleft licenses require all derivative works to use
11200-568: The software, component security and integrity, and foreign governmental influence. Another issue for governments in regard to open source is their investments in technologies such as operating systems , semiconductors , cloud , and artificial intelligence . These technologies all have implications for global cooperation, again opening up security issues and political consequences. Many countries have to balance technological innovation with technological dependence in these partnerships. For example, after China's open-source dependent company Huawei
11312-425: The software. Commercial pressures make traditional software developers pay more attention to customers' requirements than to security requirements, since such features are somewhat invisible to the customer. In open-source software development, tools are used to support the development of the product and the development process itself. Version control systems such as Centralized Version control system (CVCS) and
11424-426: The strength of response to a single stimulus due to repeated exposure to that stimulus." This definition exempts the changes caused by sensory adaptation , fatigue , or injury. Non-associative learning can be divided into habituation and sensitization . Habituation is an example of non-associative learning in which one or more components of an innate response (e.g., response probability, response duration) to
11536-597: The terms incorrect and misleading. Stallman also opposes the professed pragmatism of the Open Source Initiative , as he fears that the free software ideals of freedom and community are threatened by compromising on the FSF's idealistic standards for software freedom. The FSF considers free software to be a subset of open-source software, and Richard Stallman explained that DRM software, for example, can be developed as open source, despite that it does not give its users freedom (it restricts them), and thus does not qualify as free software. In his 1997 essay The Cathedral and
11648-399: The topic of mathematics. Daily life experiences take place in the workforce, family life, and any other situation that may arise during one's lifetime. Informal learning is voluntary from the learner's viewpoint, and may require making mistakes and learning from them. Informal learning allows the individual to discover coping strategies for difficult emotions that may arise while learning. From
11760-514: The traditional model of development, which he called the cathedral model, development takes place in a centralized way. Roles are clearly defined. Roles include people dedicated to designing (the architects), people responsible for managing the project, and people responsible for implementation. Traditional software engineering follows the cathedral model. The bazaar model, however, is different. In this model, roles are not clearly defined. Some proposed characteristics of software developed using
11872-437: The use and modification of the code. It is an explicit "feature" of open source that it puts very few restrictions on the use or distribution by any organization or user, in order to enable the rapid evolution of the software. According to Feller et al. (2005), the terms "free software" and "open-source software" should be applied to any "software products distributed under terms that allow users" to use, modify, and redistribute
11984-419: The world, learn the rules, and learn to interact through play. Lev Vygotsky agrees that play is pivotal for children's development, since they make meaning of their environment through playing educational games. For Vygotsky, however, play is the first form of learning language and communication, and the stage where a child begins to understand rules and symbols. This has led to a view that learning in organisms
12096-687: Was also chosen by Hewlett-Packard as the CAS for their HP Prime calculator, which utilizes the Giac/Xcas 1.5.0 engine under a dual-license scheme. In 2013, the mathematical software Xcas was also integrated into GeoGebra 's CAS view. Since 2015, Xcas is used in the French education system . Xcas is also used in German universities , and in Spain and Mexico . It is also used at the University of North Carolina Wilmington and
12208-404: Was much debate on whether to protect it as intellectual property under patent law , copyright law or establishing a unique regulation. Ultimately, copyright law became the standard with computer programs being considered a form of literary work, with some tweaks of unique regulation. Software is generally considered source code and object code , with both being protectable, though there
12320-449: Was prevented from using Google's Android system in 2019, they began to create their own alternative operating system: Harmony OS . Germany recently established a Sovereign Tech Fund , to help support the governance and maintenance of the software that they use. Studying Learning is the process of acquiring new understanding , knowledge , behaviors , skills , values , attitudes , and preferences . The ability to learn
12432-419: Was recently also demonstrated in garden pea plants. Another influential person in the world of classical conditioning is John B. Watson . Watson's work was very influential and paved the way for B.F. Skinner 's radical behaviorism. Watson's behaviorism (and philosophy of science) stood in direct contrast to Freud and other accounts based largely on introspection. Watson's view was that the introspective method
12544-462: Was too subjective and that we should limit the study of human development to directly observable behaviors. In 1913, Watson published the article "Psychology as the Behaviorist Views", in which he argued that laboratory studies should serve psychology best as a science. Watson's most famous, and controversial, experiment was " Little Albert ", where he demonstrated how psychologists can account for
