Provides a framework for understanding the concept of validity and how it applies to simulation research. Extant tests of validity are discussed in terms of this framework, and a general schema for testing validity is proposed. (MBR)

Suggests the use of computer simulation of continuous systems as a problem solving approach to computer languages. Outlines the procedures that the system dynamics approach employs in computer simulations. Explains the advantages of the special purpose language, DYNAMO. (ML)

Cites advances in x-ray diffraction, nuclear magnetic resonance, computer modeling, and display to guide the design and analysis of protein structures. Reviews recent advances in knowledge, synthesis techniques, and theory of proteins. (JM)

Meaningful educational activities and cognitive tools might improve students' active involvements in the teaching-learning process and encourage their reflections on the concepts and relations to be investigated. It is claimed that usage of manipulatives not only increase students' conceptual understanding and problem solving skills but also…

Leading-edge technologies, integrated with emerging educational methodologies, make the Advanced Learning Environment (ALE) model cost effective and efficient for learning. The ALE integrates virtual reality and other enabling technologies such as natural language processing, animation, video, courseware, sound, projection, CD-ROM, and distance…

A literature review explored answers to questions about the relationship between the business world and entrepreneurship education, including the question of whether models of reality actually mirror real-life situations. The review showed that between 1979 and 1994, entrepreneurship education grew phenomenally, whereas business education did not…

Discusses a computer simulation designed as an educational tool for students to observe predator-prey oscillations and experimentally investigate how changes in life histories affect predator and prey densities. Provides hands-on interaction with such theories and with mathematical models. Available to any instructor for curriculum use. (AIM)

Examines the need to match teaching processes to cognitive aspects of learning and motivational dynamics of learners within the context of computer assisted instruction (CAI). Discusses how theories and empirical findings of research on motivation can be integrated in a formal model in order to describe and predict motivation within the framework…

Review of research and development on the design of computer-based simulation for diagnostic training highlights the development and evaluation of eight diagnostic training systems that explored the appropriate level of student modeling needed for technology training. Topics addressed include changes in interface design, displays, and system…

Describes how computer simulations can enhance students' learning of physiology. Discusses how computer models enhance experimentation; using computer modeling in high school science; three steps in students' writing of a simulation; and the value of simulations. Lists six software vendors who offer packages on the PC or Macintosh platforms. (AEF)

Discusses a computerized cost-simulation model, BRIDGE, designed to compare the cost of expanding a campus using distance instruction to that of classroom instruction. Discusses cost comparison examples from classroom, television/broadcast, and asynchronous network courses. The model also demonstrates the cost-saving potential of sharing courses…

Presents an interactive simulation model on which the academic aspects of university management can be analyzed and alternative management strategies tested. Focuses specifically on long-term, dynamic, strategic management problems and yields performance measures about the fundamental activities in a university that can support strategic…

Reviews an article that explains BRIDGE, a computerized cost simulation model that compares the cost of expanding a campus through distance instruction versus traditional classrooms. Results of case studies showed that if a television broadcast-delivered class has an enrollment of 150-300 it can be cost competitive with the traditional classroom.…

Discusses the design and use of intelligent tutoring systems (ITS) for computerized business simulations. Reviews the use of ITS as an instructional technology; presents a model for ITS-based business simulations; examines the user interface and link between the ITS and simulation; and recommends expert-consultant diagnostic testing, and…

Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according…
