Describes an activity which uses the computer to produce an environment that encourages an inductive reasoning approach to ratio and proportion through a billiard ball simulation. Provides examples of graphs and bouncing ball data. (RT)

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

Examines mathematics problem solving in a computer software environment using graphical representations of the results of simulations with adolescent students. Discusses the strengths and limitations of inferring goals and plans, the use of verbal protocols, and ways for computer-based learning environments to scaffold acquisition of domain…

Reports on a pilot study that examined use by sixth-grade students in Costa Rica of a mathematical microworld written in LOGO. The investigation had three phases: (1) open exploration of the microworld; (2) group discussion and sharing of hypotheses; and (3) guided discovery and problem solving. (Contains 11 references.) (SLW)

This pamphlet presents brief reviews of 38 population education software and online systems currently available. It includes mathematical models, simulations, databases, problem-solving games, online systems, and associations. The review includes a description of the program, the level at which it is aimed, required computer hardware, the vendor's…

This report describes the first of three stages in a study in the domain of problem solving: the definition and explication of schema knowledge. One objective of this research is to understand how schema knowledge is acquired and used in the chosen domain. The focus is on ways in which instruction influences the development of specific knowledge…

"Sherlock" is a computer-based, supported practice environment for a complex troubleshooting job in Air Force electronics. The program was developed to raise the level of troubleshooting knowledge of avionics technicians. This describes the training problem for which Sherlock was developed, the principles behind its development, and its…

A project to (1) develop and apply a microcomputer simulation program to enhance clinical medication problem solving in preclerkship and clerkship students and (2) perform an initial formative evaluation of the simulation is described. A systematic instructional design approach was used in applying the simulation to the disease state of rheumatoid…

Presents thinking-aloud protocols from secondary pupils solving arithmetic story and geometrical problems and analyzes their protocols by using interpretation models founded on a general problem-solving model. A word problem solving simulation is also used to further explicate processes pupils use to solve mathematical tasks. (Author/MBR)

Presents practical teaching suggestions selected from commercially available materials and also submitted by readers that can be easily adapted to different grade levels. Includes seven computer-based activities on topics such as map-making, word games, database logic, concatenation, and one-line programs. (ML)

This study investigated the impact of integrated learning systems, problem solving software, and simulation software on elementary students' reading performance. Results indicate students entering fourth through sixth grade profited more from instruction supplemented by problem-solving and simulation software than from skills instruction. Results…

Discussion of the evaluation of courseware focuses on a study conducted to evaluate the Health and Fitness Assessment (HAFA) program, which was designed to elicit problem solving skills to assess health and fitness parameters and develop exercise prescriptions. Protocol analysis is described and the analysis of interpretive statements is…
