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)

Describes a series of computer programs that use simulation and gaming techniques to present the basic principles of the central dogma of molecular genetics, mutation, and the genetic code. A history of discoveries in molecular biology is presented and the evolution of these computer assisted instructional programs is described. (MBR)

Reviews computer programs for simulating experiments on (1) polymer sequencing; (2) genetic codes; and (3) cloning. Reasons for using such software are provided. (DH)

Describes software packages on energy topics which are undergoing teacher reviews and testing. Although all are intended primarily for grades seven to 12, some are also appropriate for higher education. Program topics include power plant engineer, energy conversions, personal energy inventory, temperature grapher, home energy savings, and electric…

In providing an alternative view to the previous article by Ward (TM 508 880), the author notes problems associated with adaptive testing, diagnostic testing, testing embedded in instruction, and testing through simulations. (BW)

Computer simulations are one promising tool for supporting learning at all levels--from elementary school to workplace learning. Learning through simulations, either by creating simulations or by exploring existing ones, helps learners develop a deeper understanding of the concepts being simulated. Learning about simulations is also important…

Discussed are the use of probability simulations in a mathematics classroom. Computer simulations using regular dice and special dice are described. Sample programs used to generate 100 rolls of a pair of dice in BASIC and Logo languages are provided. (YP)

Discusses two type of computer programs--grade book programs and classroom simulations--and how they are used by teachers. Using instructor-developed programs as examples, Campion describes his experiences as a programer and encourages his fellow historians to investigate the possibility of programing for themselves. (GEA)

Examines implications from cognitive psychology which are important for the design of microcomputer-based instructional simulations. Topics addressed include cognitive structure, including schemata and mental models; cognitive and metacognitive strategies; automaticity of cognitive processes; and affect, or the motivational appeal. (Contains 86…

This article examines the concept of interactivity and discusses human-to-human interactivity versus computer-to-human interaction in education. Levels of communicative interdependence are explained, variables that are important ingredients of interactivity are discussed, learner control is discussed, and two interactive instructional systems are…

Considers three main components of self-directed learning: (1) topic knowledge; (2) procedural skills; and (3) self-monitoring. The role of computer-assisted instruction in autonomous learning is discussed, software that fosters independent problem solving is reviewed, and it is recommended that computers be incorporated in courses emphasizing…

Describes a variety of computer software programs and student activities utilizing the computer to help teach secondary social studies. Suggests using word processors, painting programs, and computer simulations for history and government courses. Concludes that successful use of computers in social studies instruction depends on the design of…

Describes an intelligent tutor incorporating a program using artificial-intelligence planning methods to generate realistic audit files reporting actions of simulated users and intruders of a UNIX system, and a program simulating the system afterwards that asks students to inspect the audit and fix problems. Experiments show that students using…

Illustrates the design and implementation of a Java applet for use in educational propulsion engineering curricula. The Java Gas Turbine Simulator applet provides an interactive graphical environment which allows the rapid, efficient construction and analysis of arbitrary gas turbine systems. The simulator can be easily accessed from the World…

Presents a multimedia component kit for digital electronics authoring and learning. Components available on the Internet facilitate sharing and reuse of educational software and provide authoring support. Emphasis is put on the implementation of a number of components based on simulation and animation that provide a high level of interactivity and…
