Using the Calculator in a Prealgebra Course.
Peer reviewed Peer reviewed
Boyd, Linda H.; Carson, Virginia M. – AMATYC Review, 1991
Indicates that utilizing calculators to introduce algebraic concepts in a prealgebra course provides students with a solid foundation for the study of college mathematics. Pedagogical criteria emphasized the difference between exact and approximate results, appropriate use of the calculator in problem solving, the role of estimation in…

Effectiveness of Microcomputer Simulations in Stimulating Environmental Problem Solving by Community College Students.
Peer reviewed Peer reviewed
Farynaiarz, Joseph V.; Lockwood, Linda G. – Journal of Research in Science Teaching, 1992
Utilizes a quasiexperimental design to examine the impact of microcomputer simulations on environmental problem solving by community college students. The experimental group of students (n=34) showed a highly significant improvement in problem-solving skills after being exposed to three simulation models that focused on lake pollution analysis,…

A Comparison of the Classroom Dynamics of a Problem-Solving and Traditional Laboratory Model of Instruction Using Path Analysis.
Peer reviewed Peer reviewed
Pizzini, Edward L.; Shepardson, Daniel P. – Journal of Research in Science Teaching, 1992
Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
