Describes two types of computer-based experiments: simulation (which assumes no student knowledge of the workings of the computer program) is recommended for experiments aimed at inductive reasoning; and modeling (which assumes student understanding of the computer program) is recommended for deductive processes. (MLH)

Discusses the use, types, and advantages of simulation activities in problem-solving instruction. Reviews a research study of simulation in medical education. (MLH)

Examines a number of factors that might influence performance in a college laboratory chemistry course. Compares the achievement and time for students doing a simulated or a laboratory experiment. Tries to identify differences in performance for students of different aptitude and possible interaction between types of experiment and student…

Discusses a case study on discovery learning with a computer simulation environment in the physics domain of collisions. Finds that providing assignments with the simulation improves students' performance on one aspect of an intuitive-knowledge test. Contains 43 references. (Author/WRM)

This study investigated what constitutes exploratory learning and what effects instructional support measures have on it. Among the conclusions were that students were reluctant to apply learning processes that are considered characteristic for exploratory learning. Students had problems with the process, especially with the process of generating…

This study used a microcomputer program which diagnosed and remediated an alternative conception of velocity. Results show computer simulations are credible representations of reality and that the remedial part of the program produces significant conceptual changes in students holding the alternative conception. (Author/JN)

The purpose of this study was to examine the effects of three instructional methods and conceptual systems orientation on achievement in a freshman general chemistry laboratory course. Traditional approach, learning cycle, and computer simulations are discussed. (KR)

Describes a study of college students who designed and conducted experiments involving control of variables after being assigned to one of four versions of a computer-based biology simulation learning environment. Finds that reason-justification prompts directed students' attention to understanding the employment of experimental design principles…
