Learning is the process of acquiring new understanding , knowledge , behaviors , skills , values , attitudes , and preferences . The ability to learn 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.
119-456: SuperMemo (from "Super Memory") is a learning method and software package developed by SuperMemo World and SuperMemo R&D with Piotr Woźniak in Poland from 1985 to the present. It is based on research into long-term memory , and is a practical application of the spaced repetition learning method that has been proposed for efficient instruction by a number of psychologists as early as in
238-428: A negative or positive liberty . Due to their restrictions on distribution, not everyone considers copyleft licenses to be free. Conversely, a permissive license may provide an incentive to create non-free software by reducing the cost of developing restricted software. Since this is incompatible with the spirit of software freedom, many people consider permissive licenses to be less free than copyleft licenses. There
357-454: 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
476-550: 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
595-407: A chess piece (psychomotor). Furthermore, later in the game the person may even learn to love the game itself, value its applications in life, and appreciate its history (affective domain). 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
714-524: 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
833-431: 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
952-529: A copy of the free application itself. Fees are usually charged for distribution on compact discs and bootable USB drives, or for services of installing or maintaining the operation of free software. Development of large, commercially used free software is often funded by a combination of user donations, crowdfunding , corporate contributions, and tax money. The SELinux project at the United States National Security Agency
1071-457: A database of questions and answers constructed by the user. When reviewing information saved in the database, the program uses the SuperMemo algorithm to decide what questions to show the user. The user then answers the question and rates their relative ease of recall - with grades of 0 to 5 (0 is the hardest, 5 is the easiest) - and their rating is used to calculate how soon they should be shown
1190-453: 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
1309-561: A fee. The Free Software Foundation encourages selling free software. As the Foundation has written, "distributing free software is an opportunity to raise funds for development. Don't waste it!". For example, the FSF's own recommended license (the GNU GPL ) states that "[you] may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for
SECTION 10
#17327977213011428-450: A fee." Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source." This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release
1547-494: A for-profit, commercial activity or not. Some free software is developed by volunteer computer programmers while other is developed by corporations; or even by both. Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term "free software" rather than " open-source software " (an alternative, yet similar, concept coined in 1998), because
1666-685: 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
1785-409: 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
1904-424: 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
2023-548: 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
2142-441: 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
2261-410: A paper titled Optimization of repetition spacing in the practice of learning. Little detail is specified in the algorithms released later than that. In 1995, SM-8, which capitalized on data collected by users of SuperMemo 6 and SuperMemo 7 and added a number of improvements that strengthened the theoretical validity of the function of optimum intervals and made it possible to accelerate its adaptation,
2380-446: 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
2499-696: 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

#17327977213012618-438: 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
2737-456: 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
2856-526: 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 –
2975-583: 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 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
3094-472: 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
3213-571: A significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies . Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good . Companies that contribute to free software increase commercial innovation . "We migrated key functions from Windows to Linux because we needed an operating system that
3332-498: A small set of licenses. The most popular of these licenses are: The Free Software Foundation and the Open Source Initiative both publish lists of licenses that they find to comply with their own definitions of free software and open-source software respectively: The FSF list is not prescriptive: free-software licenses can exist that the FSF has not heard about, or considered important enough to write about. So it
3451-419: 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
3570-534: 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
3689-484: 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

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
3927-490: 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
4046-450: 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
4165-646: 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

Proprietary software, on the other hand, tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for
4403-466: Is biased by counting more vulnerabilities for the free software systems, since their source code is accessible and their community is more forthcoming about what problems exist as a part of full disclosure , and proprietary software systems can have undisclosed societal drawbacks, such as disenfranchising less fortunate would-be users of free programs. As users can analyse and trace the source code, many more people with no commercial constraints can inspect
4522-463: 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

Free software is a matter of liberty , not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program. Computer programs are deemed "free" if they give end-users (not just
4760-545: Is consistent with the intended meaning unlike the term "Open Source". The loan adjective " libre " is often used to avoid the ambiguity of the word "free" in the English language , and the ambiguity with the older usage of "free software" as public-domain software. ( See Gratis versus libre . ) The first formal definition of free software was published by FSF in February 1986. That definition, written by Richard Stallman ,

The FSF also notes that "Open Source" has exactly one specific meaning in common English, namely that "you can look at the source code." It states that while the term "Free Software" can lead to two different interpretations, at least one of them

Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing the software, and this results in reliance on
5355-495: Is not endorsed by the FSF and does not use Linux-libre, it is also a popular distribution available without kernel blobs by default since 2011. The Linux community uses the term "blob" to refer to all nonfree firmware in a kernel whereas OpenBSD uses the term to refer to device drivers. The FSF does not consider OpenBSD to be blob free under the Linux community's definition of blob. Selling software under any free-software licence

Most companies in the software business include free software in their commercial products if the licenses allow that. Free software is generally available at no cost and can result in permanently lower TCO ( total cost of ownership ) compared to proprietary software . With free software, businesses can fit software to their specific needs by changing
5593-415: Is permissible, as is commercial use. This is true for licenses with or without copyleft . Since free software may be freely redistributed, it is generally available at little or no fee. Free software business models are usually based on adding value such as customization, accompanying hardware, support, training, integration, or certification. Exceptions exist however, where the user is charged to obtain
5712-521: Is possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software, on the other hand, is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet

The numbering begins with zero, not only as a spoof on the common usage of zero-based numbering in programming languages, but also because "Freedom 0" was not initially included in the list, but later added first in the list as it was considered very important. Freedoms 1 and 3 require source code to be available because studying and modifying software without its source code can range from highly impractical to nearly impossible. Thus, free software means that computer users have

It is rare that a license announced as being in-compliance with the FSF guidelines does not also meet the Open Source Definition , although the reverse is not necessarily true (for example, the NASA Open Source Agreement is an OSI-approved license, but non-free according to FSF). There are different categories of free software. Proponents of permissive and copyleft licenses disagree on whether software freedom should be viewed as
6069-399: 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

#17327977213016188-417: 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
6307-552: 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
6426-440: 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
6545-412: 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

Learning Human learning starts at birth (it might even start before ) and continues until death as 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
6783-412: 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,
6902-491: 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

He developed a free software definition and the concept of " copyleft ", designed to ensure software freedom for all. Some non-software industries are beginning to use techniques similar to those used in free software development for their research and development process; scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under copyleft licenses ( see

According to Richard Stallman, user access to the source code makes deploying free software with undesirable hidden spyware functionality far more difficult than for proprietary software. Some quantitative studies have been done on the subject. In 2006, OpenBSD started the first campaign against the use of binary blobs in kernels . Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts
8925-739: The conditions under which transfer of learning might occur. Early research by Ruger, for example, found that the "level of attention", "attitudes", "method of attack" (or method for tackling a problem), a "search for new points of view", a "careful testing of hypothesis" and "generalization" were all valuable approaches for promoting transfer. To encourage transfer through teaching, Perkins and Salomon recommend aligning ("hugging") instruction with practice and assessment, and "bridging", or encouraging learners to reflect on past experiences or make connections between prior knowledge and current content.

9282-401: 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
9401-428: 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,
9520-477: The formal-learning systems if they get work done in informal-learning circuits. 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
9639-533: 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
9758-423: The freedom to cooperate with whom they choose, and to control the software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, the Free Software Foundation says: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in ' free speech ', not as in 'free beer ' ". ( See Gratis versus libre . ) In
9877-412: The goals and messaging are quite dissimilar. According to the Free Software Foundation, "Open source" and its associated campaign mostly focus on the technicalities of the public development model and marketing free software to businesses, while taking the ethical issue of user rights very lightly or even antagonistically. Stallman has also stated that considering the practical advantages of free software
9996-409: The government charged that bundled software was anti-competitive . While some software might always be free, there would henceforth be a growing amount of software produced primarily for sale. In the 1970s and early 1980s, the software industry began using technical measures (such as only distributing binary copies of computer programs ) to prevent computer users from being able to study or adapt
10115-513: The impression that users have an obligation (as opposed to a right) to give non-users a copy of the program. Although the term "free software" had already been used loosely in the past and other permissive software like the Berkeley Software Distribution released in 1978 existed, Richard Stallman is credited with tying it to the sense under discussion and starting the free software movement in 1983, when he launched
10234-421: The late 1990s, other groups published their own definitions that describe an almost identical set of software. The most notable are Debian Free Software Guidelines published in 1997, and The Open Source Definition , published in 1998. The BSD -based operating systems, such as FreeBSD , OpenBSD , and NetBSD , do not have their own formal definitions of free software. Users of these systems generally find
10353-537: 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
10472-454: 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
10591-437: 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
10710-421: The lifespan. Play as a form of learning, can occur solitarily, or involve interacting with others. 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
10829-406: 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
10948-560: The nature of learning can be used to make the entire process more natural for the user. Furthermore, since the process of extracting knowledge can often lead to the extraction of more information than can actually be feasibly remembered, a priority system is implemented that allows the user to ensure that the most important information is remembered when they can't review all information in the system. The specific algorithms SuperMemo uses have been published, and re-implemented in other programs. Different algorithms have been used; SM-0 refers to
11067-457: 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
11186-424: The original (non-computer-based) algorithm, while SM-2 refers to the original computer-based algorithm released in 1987 (used in SuperMemo versions 1.0 through 3.0, referred to as SM-2 because SuperMemo version 2 was the most popular of these). Subsequent versions of the software have claimed to further optimize the algorithm. Piotr Woźniak , the developer of SuperMemo algorithms, released the description for SM-5 in
11305-485: 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
11424-404: 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
11543-468: The publisher to provide updates, help, and support. ( See also vendor lock-in and abandonware ). Users often may not reverse engineer , modify, or redistribute proprietary software. Beyond copyright law, contracts and a lack of source code, there can exist additional obstacles keeping users from exercising freedom over a piece of software, such as software patents and digital rights management (more specifically, tivoization ). Free software can be
11662-621: The question again. While the exact algorithm varies with the version of SuperMemo, in general, items that are harder to remember show up more frequently. Besides simple text questions and answers, the latest version of SuperMemo supports images, video, and HTML questions and answers. Since 2000, SuperMemo has had a unique set of features that distinguish it from other spaced repetition programs, called incremental reading (IR or "increading"). Whereas earlier versions were built around users entering information they wanted to use, using IR, users can import text that they want to learn from. The user reads
11781-511: The same set of software to be acceptable, but sometimes see copyleft as restrictive. They generally advocate permissive free software licenses , which allow others to use the software as they wish, without being legally forced to provide the source code. Their view is that this permissive approach is more free. The Kerberos , X11 , and Apache software licenses are substantially similar in intent and implementation. There are thousands of free applications and many operating systems available on
11900-583: 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
12019-435: The shift in climate surrounding the computer world and its users. In his initial declaration of the project and its purpose, he specifically cited as a motivation his opposition to being asked to agree to non-disclosure agreements and restrictive licenses which prohibited the free sharing of potentially profitable in-development software, a prohibition directly contrary to the traditional hacker ethic . Software development for
12138-461: The software applications as they saw fit. In 1980, copyright law was extended to computer programs. In 1983, Richard Stallman , one of the original authors of the popular Emacs program and a longtime member of the hacker community at the MIT Artificial Intelligence Laboratory , announced the GNU Project , the purpose of which was to produce a completely non-proprietary Unix-compatible operating system, saying that he had become frustrated with
12257-443: The software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage. Such an agreement is made separately from the free software license. A report by Standish Group estimates that adoption of free software has caused
12376-411: The source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and free software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM (IBM acquired RedHat in 2019), which do substantial commercial business in the development of free software. Free software played
12495-426: 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
12614-418: The text inside of SuperMemo, and tools are provided to bookmark one's location in the text and automatically schedule it to be revisited later, extract valuable information, and turn extracts into questions for the user to learn. By automating the entire process of reading and extracting knowledge to be remembered all in the same program, time is saved from having to manually prepare information, and insights into
12733-399: 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
12852-404: The user with the cards whose last review occurred at least I days ago. For each review, the user tries to recall the information and (after being shown the correct answer) specifies a grade q (from 0 to 5) indicating a self-evaluation the quality of their response, with each grade having the following meaning: The following algorithm is then applied to update the three variables associated with
12971-495: The users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs , they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free. The issue of binary blobs in
13090-419: 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
13209-620: Was a proprietary software licence. However, with version 0.12 in February 1992, he relicensed the project under the GNU General Public License . Much like Unix, Torvalds' kernel attracted the attention of volunteer programmers. FreeBSD and NetBSD (both derived from 386BSD ) were released as free software when the USL v. BSDi lawsuit was settled out of court in 1993. OpenBSD forked from NetBSD in 1995. Also in 1995, The Apache HTTP Server , commonly referred to as Apache,
13328-402: Was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software, and some customers able to better meet their own needs did not want the costs of "free" software bundled with hardware product costs. In United States vs. IBM , filed January 17, 1969,
13447-536: Was introduced in SuperMemo 8. In 2002, SM-11, the first SuperMemo algorithm that was resistant to interference from the delay or advancement of repetitions was introduced in SuperMemo 11 (aka SuperMemo 2002). In 2005, SM-11 was tweaked to introduce boundaries on A and B parameters computed from the Grade vs. Forgetting Index data. In 2011, SM-15, which notably eliminated two weaknesses of SM-11 that would show up in heavily overloaded collections with very large item delays,
13566-472: Was introduced in Supermemo 15. In 2016, SM-17, the first version of the algorithm to incorporate the two component model of memory, was introduced in SuperMemo 17. The latest version of the SuperMemo algorithm is SM-18, released in 2019. The first computer-based SuperMemo algorithm (SM-2) tracks three properties for each card being studied: Every time the user starts a review session, SuperMemo provides
13685-419: 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
13804-476: Was released under the Apache License 1.0 . All free-software licenses must grant users all the freedoms discussed above. However, unless the applications' licenses are compatible, combining programs by mixing source code or directly linking binaries is problematic, because of license technicalities . Programs indirectly connected together may avoid this problem. The majority of free software falls under
13923-679: Was stable and reliable – one that would give us in-house control. So if we needed to patch, adjust, or adapt, we could." Official statement of the United Space Alliance , which manages the computer systems for the International Space Station (ISS), regarding their May 2013 decision to migrate ISS computer systems from Windows to Linux The economic viability of free software has been recognized by large corporations such as IBM , Red Hat , and Sun Microsystems . Many companies whose core business
14042-470: 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
14161-407: Was typically public-domain software . Software was commonly shared by individuals who used computers and by hardware manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, SHARE , were formed to facilitate exchange of software. As software was often written in an interpreted language such as BASIC ,
