Different criteria have been proposed by different researchers, the more important of which are listed below:. How do researchers build theories?

Steinfeld and Fulk [2] recommend four such approaches. The first approach is to build theories inductively based on observed patterns of events or behaviors. This technique is heavily dependent on the observational and interpretive abilities of the researcher, and the resulting theory may be subjective and non -confirmable. Furthermore, observing certain patterns of events will not necessarily make a theory, unless the researcher is able to provide consistent explanations for the observed patterns.

We will discuss the grounded theory approach in a later chapter on qualitative research. The second approach to theory building is to conduct a bottom-up conceptual analysis to identify different sets of predictors relevant to the phenomenon of interest using a predefined framework.

The third approach to theorizing is to extend or modify existing theories to explain a new context, such as by extending theories of individual learning to explain organizational learning. This deductive approach leverages the rich inventory of social science theories developed by prior theoreticians, and is an efficient way of building new theories by building on existing ones. The fourth approach is to apply existing theories in entirely new contexts by drawing upon the structural similarities between the two contexts. This approach relies on reasoning by analogy, and is probably the most creative way of theorizing using a deductive approach.

For instance, Markus [3] used analogic similarities between a nuclear explosion and uncontrolled growth of networks or network-based businesses to propose a critical mass theory of network growth. Just as a nuclear explosion requires a critical mass of radioactive material to sustain a nuclear explosion, Markus suggested that a network requires a critical mass of users to sustain its growth, and without such critical mass, users may leave the network, causing an eventual demise of the network.

In this section, we present brief overviews of a few illustrative theories from different social science disciplines. These theories explain different types of social behaviors, using a set of constructs, propositions, boundary conditions, assumptions, and underlying logic. Note that the following represents just a simplistic introduction to these theories; readers are advised to consult the original sources of these theories for more details and insights on each theory.

Agency Theory. Agency theory also called principal-agent theory , a classic theory in the organizational economics literature, was originally proposed by Ross [4] to explain two-party relationships such as those between an employer and its employees, between organizational executives and shareholders, and between buyers and sellers whose goals are not congruent with each other.

The goal of agency theory is to specify optimal contracts and the conditions under which such contracts may help minimize the effect of goal incongruence. The core assumptions of this theory are that human beings are self-interested individuals, boundedly rational, and risk-averse, and the theory can be applied at the individual or organizational level.

The two parties in this theory are the principal and the agent; the principal employs the agent to perform certain tasks on its behalf. Hence, the goal incongruence. Such asymmetry may lead to agency problems where the agent may not put forth the effort needed to get the task done the moral hazard problem or may misrepresent its expertise or skills to get the job but not perform as expected the adverse selection problem. Typical contracts that are behavior-based, such as a monthly salary, cannot overcome these problems. Hence, agency theory recommends using outcome-based contracts, such as a commissions or a fee payable upon task completion, or mixed contracts that combine behavior-based and outcome-based incentives.

An employee stock option plans are is an example of an outcome-based contract while employee pay is a behavior-based contract. Theory of Planned Behavior. Postulated by Azjen [5] , the theory of planned behavior TPB is a generalized theory of human behavior in the social psychology literature that can be used to study a wide range of individual behaviors. It presumes that individual behavior represents conscious reasoned choice, and is shaped by cognitive thinking and social pressures.

TPB also suggests that sometimes people may intend to perform a given behavior but lack the resources needed to do so, and therefore suggests that posits that behavioral control can have a direct effect on behavior, in addition to the indirect effect mediated by intention. TPB is an extension of an earlier theory called the theory of reasoned action, which included attitude and subjective norm as key drivers of intention, but not behavioral control. The latter construct was added by Ajzen in TPB to account for circumstances when people may have incomplete control over their own behaviors such as not having high-speed Internet access for web surfing.

Innovation diffusion theory. Innovation diffusion theory IDT is a seminal theory in the communications literature that explains how innovations are adopted within a population of potential adopters.

Knowledge Space Theory

The concept was first studied by French sociologist Gabriel Tarde, but the theory was developed by Everett Rogers in based on observations of diffusion studies. The four key elements in this theory are: innovation, communication channels, time, and social system. Innovations may include new technologies, new practices, or new ideas, and adopters may be individuals or organizations. At the macro population level, IDT views innovation diffusion as a process of communication where people in a social system learn about a new innovation and its potential benefits through communication channels such as mass media or prior adopters and are persuaded to adopt it.

  • Peace in motion : John Dewey and the aesthetics of well-being.
  • The Tenant of Wildfell Hall.
  • Interacting Stochastic Systems!
  • Diffusion is a temporal process; the diffusion process starts off slow among a few early adopters, then picks up speed as the innovation is adopted by the mainstream population, and finally slows down as the adopter population reaches saturation. The cumulative adoption pattern therefore an S-shaped curve, as shown in Figure 4. All adopters are not identical, and adopters can be classified into innovators, early adopters, early majority, late majority, and laggards based on their time of their adoption.

    At the micro adopter level, Rogers [6] suggests that innovation adoption is a process consisting of five stages: 1 knowledge: when adopters first learn about an innovation from mass-media or interpersonal channels, 2 persuasion: when they are persuaded by prior adopters to try the innovation, 3 decision: their decision to accept or reject the innovation, 4 implementation: their initial utilization of the innovation, and 5 confirmation: their decision to continue using it to its fullest potential see Figure 4.

    The last two characteristics have since been dropped from many innovation studies. Complexity is negatively correlated to innovation adoption, while the other four factors are positively correlated. Early adopters are venturesome, well educated, and rely more on mass media for information about the innovation, while later adopters rely more on interpersonal sources such as friends and family as their primary source of information. Elaboration Likelihood Model. The Balanced Scorecard BSC is originally a method in business economics and aims at the adjustment, measurement and documentation of activities to reach organisational goals with the help of a ratio system.

    Kaplan and David P. Cloud computing is separated into three categories: 1 infrastructure, 2 platforms, and 3 applications. All three have in common that there is no longer either a local installation or a local storage of data and documents on a computer. Everything is stored virtually on the web.

Collaborative learning aims at a collective development of a subject matter in order to gain insight into it, to gather a collective understanding and to get a collective solution for a learning problem.

    In contrast to that, cooperative learning aims at a combined product but not at a transformative learning process. Dillenbourg highlights criteria to identify a collaborative learning: 1 situation collaboration usually takes place on a common level, i. CbKST assumes a dependency relation in different knowledge areas. Basis assumption of CbKST is that skills are oriented in a certain way and build up on each other. If a person has a specific skill X which is needed to solve a certain problem and is able to solve this problem, the person will also possess all skills which are oriented underneath skill X.

    The idea is a well-balanced planning not only of learning activities but also of embedded and explicit formative appraisals in an ICT-based instruction. Each appraisal process is also facilitated by ICT to provide the teacher with learning data of individual students. These data could be used to further plan the instruction in relation to an internal differentiation of learner groups. Formative assessment recently more often referred to as assessment for learning is the counterpart of summative assessment also referred to as assessment of learning. Formative assessments describe a form of appraisal that takes place while the learning process is still ongoing and is future oriented.

    The teacher collects information about the current learning process of the student and gives feedback to the student in order to facilitate and enhance the current process. According to the OECD, formative assessment is one of the most crucial assessment strategies in order to enhance learning performance. Recent literature more and more utilizes the term assessment for learning instead of formative assessment in order to emphasize that it is about an assessment which has a constitutive influence on the learning process.

    ICT Information and Communication Technology is a collective term for all communication devices and applications e. According to the European Commission, ICT has a special influence in three key areas: 1 productivity and innovation e. Immersive learning environments ILE are learning situations using state of the art techniques like e. One key characteristic is that ILEs simulate real life displays that give the learner the opportunity to immerse into the environment in order to practice skills or interact with other learners as if the learner and other are actually in that virtual world.


    Immersive Learning Environments are used since the late s. Within a Learning Management System LMS , learning contents as well as organized learning processes are prepared and provided to the learner. A well-known example is the open-source platform Moodle. The EC defines lifelong learning LLL as all learning that takes place during the whole life with the intention of knowledge gain, qualification and capacity building. Moodle is an open-source learning management system that allows the organized preparation of learning contents and courses.

    A learner model is used to store information, characteristics and competences about a learner. It can be used as a specialized user model for specific learning situations. It aims at adaptation of the learning situation in relation to the knowledge level of a learner. However, the learner himself is not able to access the learner model content. In contrast to that, an open learner model allows access by the learner.
