Pedagogical Agent
A pedagogical agent is a concept borrowed from computer science and artificial intelligence and applied to education, usually as part of an intelligent tutoring system (ITS). It is a simulated human-like interface between the learner and the content, in an educational environment. A pedagogical agent is designed to model the type of interactions between a student and another person. Mabanza and de Wet define it as "a character enacted by a computer that interacts with the user in a socially engaging manner". A pedagogical agent can be assigned different roles in the learning environment, such as tutor or co-learner, depending on the desired purpose of the agent. "A tutor agent plays the role of a teacher, while a co-learner agent plays the role of a learning companion". History The history of Pedagogical Agents is closely aligned with the history of computer animation. As computer animation progressed, it was adopted by educators to enhance computerized learning by including a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...

Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

Intelligent Tutoring System
An intelligent tutoring system (ITS) is a computer system that aims to provide immediate and customized instruction or feedback to learners, usually without requiring intervention from a human teacher. ITSs have the common goal of enabling learning in a meaningful and effective manner by using a variety of computing technologies. There are many examples of ITSs being used in both formal education and professional settings in which they have demonstrated their capabilities and limitations. There is a close relationship between intelligent tutoring, cognitive learning theories and design; and there is ongoing research to improve the effectiveness of ITS. An ITS typically aims to replicate the demonstrated benefits of one-to-one, personalized tutoring, in contexts where students would otherwise have access to one-to-many instruction from a single teacher (e.g., classroom lectures), or no teacher at all (e.g., online homework). ITSs are often designed with the goal of providing acces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Learning Environment
The term learning environment can refer to an educational approach, cultural context, or physical setting in which teaching and learning occur. The term is commonly used as a more definitive alternative to "classroom", but it typically refers to the context of educational philosophy or knowledge experienced by the student and may also encompass a variety of learning cultures—its presiding ethos and characteristics, how individuals interact, governing structures, and philosophy. In a societal sense, learning environment may refer to the culture of the population it serves and of their location. Learning environments are highly diverse in use, learning styles, organization, and educational institution. The culture and context of a place or organization includes such factors as a way of thinking, behaving, or working, also known as organizational culture. For a learning environment such as an educational institution, it also includes such factors as operational characteristics of th ...

Automated Online Assistant
An intelligent virtual assistant (IVA) or intelligent personal assistant (IPA) is a software agent that can perform tasks or services for an individual based on commands or questions. The term "chatbot" is sometimes used to refer to virtual assistants generally or specifically accessed by online chat. In some cases, online chat programs are exclusively for entertainment purposes. Some virtual assistants are able to interpret human speech and respond via synthesized voices. Users can ask their assistants questions, control home automation devices and media playback via voice, and manage other basic tasks such as email, to-do lists, and calendars with verbal commands. A similar concept, however with differences, lays under the dialogue systems. As of 2017, the capabilities and usage of virtual assistants are expanding rapidly, with new products entering the market and a strong emphasis on both email and voice user interfaces. Apple and Google have large installed bases of users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Animation
Computer animation is the process used for digitally generating animations. The more general term computer-generated imagery (CGI) encompasses both static scenes (still images) and dynamic images (moving images), while computer animation refers to moving images. Modern computer animation usually uses 3D computer graphics to generate a three-dimensional picture. The target of the animation is sometimes the computer itself, while other times it is film. Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. Computer-generated animations can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props. To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new image that is similar to it but advanced slightly in time (usually at a ra ...

Office Assistant
The Office Assistant is a discontinued intelligent user interface for Microsoft Office that assisted users by way of an interactive animated character which user interface, interfaced with the Office help content. It was included in Microsoft Office, Microsoft Office for Windows (versions 97 to 2003), in Microsoft Publisher and Microsoft Project (versions 98 to 2003), Microsoft FrontPage (versions 2002 and 2003), and Microsoft Office, Microsoft Office for Mac (versions 98 to 2004). The default assistant in the English version was named Clippit (commonly nicknamed Clippy), after a paperclip. The character was designed by Kevan J. Atteberry. Clippit was the default and by far the most notable Assistant (partly because in many cases the setup CD was required to install the other assistants), which also led to it being called simply the Microsoft Paperclip. The original Clippit from Microsoft Office 97, Office 97 was given a new look in Microsoft Office 2000, Office 2000. The feature ...

Distributed Cognition
Distributed cognition is an approach to cognitive science research that was developed by cognitive anthropologist Edwin Hutchins during the 1990s. From cognitive ethnography, Hutchins argues that mental representations, which classical cognitive science held that are within the individual brain, are actually distributed in sociocultural systems that constitute the tools to think and perceive the world. Thus, a native of the Carolina Islands can perceive the sky and organize his perceptions of the constellations typical of his culture (the groupings of stars are different than in the traditional constellations of the West) and use the position of the stars in the sky as a map to orient himself in space while sailing overnight in a canoe. According to Hutchins, cognition involves not only the brain but also external artifacts, work teams made up of several people, and cultural systems for interpreting reality (mythical, scientific, or otherwise). Distributed cognition theory is part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sociocultural Perspective
Sociocultural Perspective is a theory used in fields such as psychology and education and is used to describe awareness of circumstances surrounding individuals and how their behaviors are affected specifically by their surrounding, social and cultural factors. According to Catherine A. Sanderson (2010) “Sociocultural perspective: A perspective describing people’s behavior and mental processes as shaped in part by their social and/or cultural contact, including race, gender, and nationality.” Sociocultural perspective theory is a broad yet significant aspect in our being. It applies to every sector of our daily lives. How we communicate, understand, relate and cope with one another is partially based on this theory. Our spiritual, mental, physical, emotional, physiological being are all influenced by factors studied by sociocultural perspective theory. Ideology Various studies examine topics using the sociocultural perspective in order to account for variability from person t ...

Cognitive Load
In cognitive psychology, cognitive load refers to the amount of working memory resources used. 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 (a schema). Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller. Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load. Task-invoked pupillary response is a reliable and sensitive measurement of cognitive load that is directly related to working memory. Information may only be stored in long term memory after first being attended to, and processed by, working memory. Workin ...

Split Attention Effect
The split-attention effect is a learning effect inherent within some poorly designed instructional materials. It is apparent when the same modality (e.g. visual) is used for various types of information within the same display. Users must split their attention between the materials, for example, an image and text, to understand the information being conveyed. The split-attention effect can occur physically through visual and auditory splits and temporally when time distances two pieces of information that should be connected. A visual example of split attention Consider the graphic below from Tarmizi and Sweller. They used these graphics to compare the learning that takes place given split attention conditions. Each is a possibility of how one might arrange graphical material within a lesson. Ward and Sweller advise instructional designers to be careful when they direct a learner's attention. In several studies and experiments, Sweller and his associates found that learners had diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agency (sociology)
In social science, agency is the capacity of individuals to have the power and resources to fulfill their potential. For instance, structure consists of those factors of influence (such as social class, religion, gender, ethnicity, ability, customs, etc.) that determine or limit agents and their decisions. The influences from structure and agency are debated—it is unclear to what extent a person's actions are constrained by social systems. One's agency is one's independent capability or ability to act on one's will. This ability is affected by the cognitive belief structure which one has formed through one's experiences, and the perceptions held by the society and the individual, of the structures and circumstances of the environment one is in and the position one is born into. Disagreement on the extent of one's agency often causes conflict between parties, e.g. parents and children. History The overall concept of agency has existed since the Enlightenment where there was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
