To summarize, the elaboration model of instruction starts by presenting knowledge at a very general or simplified level in the form of a special kind of overview. Then it proceeds to add detail or complexity in "layers" across the entire breadth of the content of the course (or curriculum), one layer at a time, until the desired level of detail or complexity is reached.

They soon switched to a model based on the elaboration theory (Reigeluth, 1999). Using this approach, the game would begin with a level that offered the simplest version of the whole task (the epitome); subsequent levels would become increasingly more complex--an approach common to videogames--with opportunities for review and synthesis.

Other major issues involve the accepted methods by which fidelity is measured. There are two major methods described in the literature for fidelity measurement. The first is through mathematical measurement that calculates the number of identical elements shared between the real world and the simulation; the greater the number of shared identical elements, the higher the simulation fidelity. A second method to measure fidelity is through a trainees' performance matrix.

Liu et al. (2009) identified two major methods for measuring fidelity. The first is a mathematical (objective) method that requires counting "the number of identical elements shared between the real world and the simulation; the greater the number of shared identical elements, the higher the simulation fidelity" (p. 62). The second method involves a performance matrix that compares a human's performance in the simulation with that person's real-world performance, producing an indirect measure of fidelity.

Educational researchers, policymakers, and practitioners agree that educational research is often divorced from the problems and issues of everyday practice--a split that creates a need for new research approaches that speak directly to problems of practice (National Research Council [NRC], 2002) and that lead to the development of "usable knowledge" (Lagemann, 2002). Design-based research (Brown, 1992; Collins, 1992) is an emerging paradigm for the study of learning in context through the systematic design and study of instructional strategies and tools. We argue that design-based research can help create and extend knowledge about developing, enacting, and sustaining innovative learning environments.

A decade later, researchers interested in studying learning in naturalistic settings (inspired by Brown's approach) began a concerted effort to define the standards and argue the legitimacy of this type of research through design. For example, the Design-Based Research Collective defined design-based research (DBR) as "an emerging paradigm for the study of learning in context, through the systematic design and study of instructional strategies and tools" (DBRC, 2003, p. 5).

The study of learning derives from essentially two sources.Because learning involves the acquisition of knowledge, the first concerns the nature of knowledge and how we come to know things.... The second source in which modern learning theory is rooted concerns the nature and representation of mental life.

In examining the history of the visionary companies, we were struck by how often they made some of their best moves not by detailed strategic planning, but rather by experimentation, trial and error, opportunism, and--quite literally--accident. What looks in hindsight like a brilliant strategy was often the residual result of opportunistic experimentation and "purposeful accidents."

When I look back on the decisions I've made, it's clear that I made some of my best choices not through a thorough analytical investigation of my options, but instead by trial and error and, often, simply by accident. The somewhat random aspect of my success or failure is, at the same time, both encouraging and scary.

A communication channel is the means by which messages get from one individual to another.The nature of the information-exchange relationship between a pair of individuals determines the conditions under which a source will or will not transmit the innovation to the receiver and the effect of such a transfer.

Rogers, E. M. (2003). Diffusion of innovations (5th ed.). New York: Simon & Schuster.

Rogers places great importance on the sharing of information about an innovation. He defines a communication channel as "the means by which messages get from one individual to another" (p. 18). He describes two general media channels of communication: mass media and interpersonal; and two scopes of channels: localite and cosmopolite.

The philosophical position known as constructivism views knowledge as a human construction. The various perspectives within constructivismare based on the premise that knowledge is not part of an objective, external reality that is separate from the individual. Instead, human knowledge, whether the bodies of content in public disciplines (such as mathematics or sociology) or knowledge of the individual learner, is a human construction.

Does knowledge exist outside of, or separate from, the individual who knows? Constructivists argue that "... human knowledge, whether the bodies of content in public disciplines (such as mathematics or sociology) or knowledge of the individual learner, is a human construction."

Precedent is also described as "the unique knowledge embedded in a known design" (Oxman, 1994, p. 146), meaning, in everyday terms, that the memory of having experienced an existing design is a memory that contains special forms of knowledge... At heart, the design case is a description of a real artifact or experience that has been intentionally designed. A case may be as minimal as an individual image of a commercial product, a building, an advertisement, a classroom or anything else designed; these forms of design cases appear in hundreds of magazines, design annuals, competition catalogs, display books, web portfolios and similar venues.

According to Boling (2010, p. 2), "At heart, the design case is a description of a real artifact or experience that has been intentionally designed." She explains that the primary goal of a design case is to provide designers with precedent--defined by Oxman as "the unique knowledge embedded in a known design" (as quoted in Boling, 2010, p. 2). She further explains that expert designers are aware of numerous precedents which may be helpful in future designs. For example, educational game designers can view unique cases of game designs as precedents, which, in turn, may facilitate design of new games.

It is helpful to think in terms of two basic kinds of change: piecemeal and systemic. Piecemeal change leaves the structure of a system unchanged. It often involves finding better ways to meet the same needs, such as using an analogy to help your students learn the science concepts you taught in an otherwise similar manner last year. In contrast, systemic change entails modifying the structure of a system, usually in response to new needs.

Reiguleth (1999) mentions two different kinds of change: Piecemeal and Systemic change. Systemic change entails modifying the structure of a system, in order to meet new needs. In contrast, piecemeal change leaves the structure of a system unchanged. For example, new innovations instead of traditional methods could be used to engage students in learning.
