Media adequacy refers to specific (i.e. media) aspects that are important for a successful transfer of information. This implies that not all information can be reproduced in an equally adequate way with every medium.
The successful transfer of information depends on various aspects. An important aspect is of course the content itself. Depending on the goal, purpose and methods, the question of whether and why an information transfer is successful can depend on a more or less successful content preparation. Further decisive factors can lie in the reception and the user's specific situation in its context (which is examined in recipient research, learner research, etc.), as well as in the social situation, which in turn depends on a variety of aspects, such as gender, culture, learning style etc. It is however often underestimated that the channel via which information is transferred can also be of decisive importance. Question then is which medium makes it possible to convey a specific content as well as possible (and which medium is more of a hindrance).
In general, it can be said that not all content can be transmitted equally well with every medium. One example is the Watergate Affair, which after all led to the fall of a US president. It was uncovered by a daily newspaper that is read by relatively few (though certainly influential and opinion-forming) people - but not by television, which is seen by many more viewers. The main reason is that television reports are only effective if they can be illustrated; this was hardly possible in the case of television reports about an illegal wiretapping. In the newspaper, on the other hand, it was possible to describe how the information from an (anonymous, i.e. not visually known) source was verified. The medium and its production constraints thus (partly) decide whether and how content can be presented or how effective the transfer of information is.
As a rule, the respective research is normative and it is investigated what influences (promotes or hinders) a successful transfer of information: Only what can be realised sensibly and efficiently in a particular medium should also be realised in that medium. If the researcher's perspective is not based on the recipient or the content, but on the medium, media adequacy is the central category. Only what can be realised sensibly and efficiently in a particular medium should also be realised in that medium.
The term “medium” refers not only to the means of communication, but also to different genres. In the case of the Watergate Affair, for example, the transfer of information with the help of television was only successful in the form of secondary reporting. This did not mean, however, that visual communication is fundamentally impossible with a topic like this. The genre of the feature film was very successful and effective ("All the President's Men"). The question of media adequacy thus relates more to genres (in the field of print media: text types) and not only to primary media.
In addition to the constraints of production, the conditions of reception also play a role. Content on a website has a different effect when it is received on a tablet or a stationary computer. Using one and the same content via the Internet is more successful compared to working with the same content on a DVD. [1] Thus, the medium is as important as other variables, for example the learner type (social learner type, introspective learner type). Another example: Icelandic singer Björk was the first artist to promote a music album not only with music videos but also with interactive apps; this app compilation, created by media artist Scott Snibbe, was later acquired by the Museum of Modern Art as the first downloadable app artwork. [2] From an innovative and artistic point of view, this was a remarkable achievement. However, the compilation proved to be counterproductive in terms of its effect on the music to which the apps, like music videos, were intended to relate. Although music videos offer additional visual information that can distract from the music, they generally support the respective song and focus attention on the piece of music. In contrast, the interactive apps were cognitively dominant and were therefore unable to develop the effect for which they were produced. [3]
Ultimately, it is a question of complex interactions between content, medium and reception process.
In contrast to, for example, content analysis or reception or learner research, the scientific study of media adequacy is relatively new. It is only since the triumph of microelectronics that not only specialists have been able to publish with their medium. Meanwhile, in many areas there is the possibility (and opportunity, but often also the compulsion) to work cross-medially, so that the question of the appropriate (media-adequate) presentation of content becomes urgent.
There are various theories about the use of media in different contexts and regarding different objectives. The approaches of Herbert Marshall McLuhan are well known, [4] as is the "media richness theory" by Richard Daft and Robert Lengel. [5] Daft and Lengel speak of different degrees of "media richness" depending on how much the media is absorbed: Less "rich" media are not intensive enough to attract a user's full and undisturbed attention (for example: discussion forums, chats, e-mails or other forms of textual communication). This almost inevitably leads to a certain attention deficit. The use of weak media therefore means that utilising such media requires a greater cognitive effort on the part of the user. [6] Perhaps this is why greater self-discipline is required in the context of media-supported learning than in traditional learning situations.
Relatively new, however, is the attempt to link media theory statements with studies on cognitive styles., [7] [8] Usually it is referred to traditional teaching, and it of course has to be taken into consideration that there are differences between information processing and learning (Rehder/Hoffmann 2005). [9] The common factor, however, is how one takes in and processes information [10] and might even be able to adopt to new developments, to solve problems and reaches decisions. [11] A pioneering theoretical approach to this is, for example, the "cognitive load theory" [12] that relates considerations from Robert J. Sternberg [13] to media effects.
Sternberg's "theory of mental self-government" is quite complex and therefore sometimes difficult to operationalise. It assumes that under ideal (and free) conditions learners organise the learning process in accordance with their cognitive abilities. This leads to different forms of mental representations or different codings, and thus to different forms of how to use media.
All in all, it seems to be clear that a successful information transfer depends on the situation and the strategies of how content is mediatised. With some users, it might be successful in the context of interactive group processes, whilst others need quietness to concentrate. This example has been chosen because it connects cognitive styles with media effects. The former group will probably benefit significantly from discussion forums. For introspective users, on the other hand, they would more likely be a hindrance in the process of a successful information transfer. [14] Another example: it has also long been known that some - not all - learners learn best by observing. [15] Obviously, mirror neurons become active when they see corresponding efforts by other learners, so that their self-motivation and ultimately their learning success increases. Here it can be assumed that examples from the media (such as television programmes) can also have a positive effect. Conversely, other learners must have their own experiences in order to store and process information successfully. Mediated communication therefore means a limitation for them; on the other hand, it could be that users with individual concepts for learning have an advantage through and in online learning environments - at least compared to the 'observant learner type'.
Furthermore, different cognitive styles require a different density and volume of information in order to ultimately benefit from information transfer efforts in the context of meta cognitive processes. [16] Perhaps this explains the findings of Baruch and Nicholson, [17] who observed that learners with a high tendency to avoid uncertainty - i.e. who have only a low willingness to take risks - tend to feel uncomfortable with self-learning media. There are also parallels to another observation described above: Since online media increase the degree of ambiguity both in terms of tasks and expectations of the respective user, users with a lower tolerance of uncertainty avoidance are disadvantaged, while users with a higher degree of uncertainty avoidance can even generate further advantages.
In assessing whether the use is meaningful at all, the observation that a media-supported information transfer is fundamentally more time-intensive than traditional learning also seems significant. [18] Accordingly, it is important to use media-supported learning materials in such a way that the added value in terms of content is correspondingly high and the majority of learners benefit from it.
There are other variables whose effects for a successful information transfer by now have been little or not at all investigated, at least not from a media perspective (such as gender, the cultural imprint of the media user, etc.). Summarising, it is desirable to know whether and how a media-supported information transfer can be established sensibly and efficiently. However, it is questionable whether a system can be developed that links content, user type and medium, since the mentioned variables and their interactions already give rise to too many different situations, not least since technical developments are constantly changing the media and their effects.
Learning theory describes how students receive, process, and retain knowledge during learning. Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a worldview, is acquired or changed and knowledge and skills retained.
The theory of multiple intelligences (MI) proposes the differentiation of human intelligence into specific distinguishable multiple intelligences, rather than defining it as a single general ability. Since 1983, the theory has been popular among educators around the world. In the influential book Frames of Mind: The Theory of Multiple Intelligences (1983) and its sequels, Howard Gardner identifies at least eight distinct intelligences that humans use to survive, thrive and build civilization. The theory describes intelligence as the "brain's toolkit" for creating symbolic thought that is mobilized within one’s specific culture.
Instructional design (ID), also known as instructional systems design and originally known as instructional systems development (ISD), is the practice of systematically designing, developing and delivering instructional materials and experiences, both digital and physical, in a consistent and reliable fashion toward an efficient, effective, appealing, engaging and inspiring acquisition of knowledge. The process consists broadly of determining the state and needs of the learner, defining the end goal of instruction, and creating some "intervention" to assist in the transition. The outcome of this instruction may be directly observable and scientifically measured or completely hidden and assumed. There are many instructional design models, but many are based on the ADDIE model with the five phases: analysis, design, development, implementation, and evaluation.
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, 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.
Instructional scaffolding is the support given to a student by an instructor throughout the learning process. This support is specifically tailored to each student; this instructional approach allows students to experience student-centered learning, which tends to facilitate more efficient learning than teacher-centered learning. This learning process promotes a deeper level of learning than many other common teaching strategies.
In psychology, cognitivism is a theoretical framework for understanding the mind that gained credence in the 1950s. The movement was a response to behaviorism, which cognitivists said neglected to explain cognition. Cognitive psychology derived its name from the Latin cognoscere, referring to knowing and information, thus cognitive psychology is an information-processing psychology derived in part from earlier traditions of the investigation of thought and problem solving.
Situated learning is a theory that explains an individual's acquisition of professional skills and includes research on apprenticeship into how legitimate peripheral participation leads to membership in a community of practice. Situated learning "takes as its focus the relationship between learning and the social situation in which it occurs".
Learning styles refer to a range of theories that aim to account for differences in individuals' learning. Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, few studies have found validity in using learning styles in education. Many theories share the proposition that humans can be classified according to their "style" of learning, but differ on how the proposed styles should be defined, categorized and assessed. A common concept is that individuals differ in how they learn.
Kinesthetic learning, kinaesthetic learning, or tactile learning is learning that involves physical activity. As cited by Favre (2009), Dunn and Dunn define kinesthetic learners as students who prefer whole-body movement to process new and difficult information. However, scientific studies do not support the claim that using kinesthetic modality improves learning in students identified as kinesthetic learning as their preferred learning style.
Second-language acquisition (SLA), sometimes called second-language learning—otherwise referred to as L2acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. This involves learning an additional language after the first language is established, typically through formal instruction or immersion. A central theme in SLA research is that of interlanguage: the idea that the language that learners use is not simply the result of differences between the languages that they already know and the language that they are learning, but a complete language system in its own right, with its own systematic rules. This interlanguage gradually develops as learners are exposed to the targeted language. The order in which learners acquire features of their new language stays remarkably constant, even for learners with different native languages and regardless of whether they have had language instruction. However, languages that learners already know can have a significant influence on the process of learning a new one. This influence is known as language transfer.
Cumulative learning is the cognitive process by which we accumulate and improve knowledge and abilities that serve as building blocks for subsequent cognitive development. A primary benefit of such is that it consolidates knowledge one has obtained through experience, and allows the facilitation of further learning through analogical knowledge transfer. This is seen through students' ability to transfer knowledge across contexts and through time.
In cognitive psychology, cognitive load refers to the amount of working memory resources used. However, it is essential to distinguish it from the actual construct of Cognitive Load (CL) or Mental Workload (MWL), which is studied widely in many disciplines. According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: intrinsic cognitive load is the effort associated with a specific topic; extraneous cognitive load refers to the way information or tasks are presented to a learner; and germane cognitive load refers to the work put into creating a permanent store of knowledge. However, over the years, the additivity of these types of cognitive load has been investigated and questioned. Now it is believed that they circularly influence each other.
Theories of technological change and innovation attempt to explain the factors that shape technological innovation as well as the impact of technology on society and culture. Some of the most contemporary theories of technological change reject two of the previous views: the linear model of technological innovation and other, the technological determinism. To challenge the linear model, some of today's theories of technological change and innovation point to the history of technology, where they find evidence that technological innovation often gives rise to new scientific fields, and emphasizes the important role that social networks and cultural values play in creating and shaping technological artifacts. To challenge the so-called "technological determinism", today's theories of technological change emphasize the scope of the need of technical choice, which they find to be greater than most laypeople can realize; as scientists in philosophy of science, and further science and technology often like to say about this "It could have been different." For this reason, theorists who take these positions often argue that a greater public involvement in technological decision-making is desired.
Media richness theory (MRT), sometimes referred to as information richness theory, is a framework used to describe a communication medium's ability to reproduce the information sent over it. It was introduced by Richard L. Daft and Robert H. Lengel in 1986 as an extension of information processing theory. MRT is used to rank and evaluate the richness of certain communication media, such as phone calls, video conferencing, and email. For example, a phone call cannot reproduce visual social cues such as gestures which makes it a less rich communication media than video conferencing, which affords the transmission of gestures and body language. Based on contingency theory and information processing theory, MRT theorizes that richer, personal communication media are generally more effective for communicating equivocal issues in contrast with leaner, less rich media.
Concept learning, also known as category learning, concept attainment, and concept formation, is defined by Bruner, Goodnow, & Austin (1956) as "the search for and testing of attributes that can be used to distinguish exemplars from non exemplars of various categories". More simply put, concepts are the mental categories that help us classify objects, events, or ideas, building on the understanding that each object, event, or idea has a set of common relevant features. Thus, concept learning is a strategy which requires a learner to compare and contrast groups or categories that contain concept-relevant features with groups or categories that do not contain concept-relevant features.
E-learning theory describes the cognitive science principles of effective multimedia learning using electronic educational technology.
Media naturalness theory is also known as the psychobiological model. The theory was developed by Ned Kock and attempts to apply Darwinian evolutionary principles to suggest which types of computer-mediated communication will best fit innate human communication capabilities. Media naturalness theory argues that natural selection has resulted in face-to-face communication becoming the most effective way for two people to exchange information.
Learning analytics is the measurement, collection, analysis and reporting of data about learners and their contexts, for purposes of understanding and optimizing learning and the environments in which it occurs. The growth of online learning since the 1990s, particularly in higher education, has contributed to the advancement of Learning Analytics as student data can be captured and made available for analysis. When learners use an LMS, social media, or similar online tools, their clicks, navigation patterns, time on task, social networks, information flow, and concept development through discussions can be tracked. The rapid development of massive open online courses (MOOCs) offers additional data for researchers to evaluate teaching and learning in online environments.
Channel expansion theory (CET) states that individual experience serves as an important role in determining the level of richness perception and development towards certain media tools. It is a theory of communication media perception that incorporates experiential factors to explain and predict user perceptions of a given media channel. The theory suggests that the more knowledge and experience users gain from using a channel, the richer they perceive the medium to be. The more experience, the more stable the knowledge base the person builds, the more knowledge he gains from the given media channel, thus the richer communication he would have using that channel, and ultimately the richer he would perceive the channel. There are four experiential factors that shapes individual's perceived media richness: experience with the channel, experience with the message topic, experience with the organizational context, and experience with a communication partner.
Meaningful learning refers to the act of higher order thinking and development through intellectual engagement that uses pattern recognition and concept association. It can include—but is not limited to—critical and creative thinking, inquiry, problem solving, critical discourse, and metacognitive skills. The concept and theory of meaningful learning is that learned information is completely understood and can now be used to make connections with other previously known knowledge aiding in further understanding. Since information is stored in a network of connections, it can be accessed from multiple starting points depending on the context of recall. Meaningful learning is often contrasted with rote learning, a method in which information is memorized sometimes without elements of understanding or relation to other objects or situations. A real-world example of a concept the learner has learned is an instance of meaningful learning.
