The study examined whether embedding the linear equations and ratio and proportion strategies used to solve percent problems in the higher-order structures of proportional logic and group properties would aid achievement. Thus, it examined the interaction in differences in understanding fundamental structures in mathematics, and instruction…

Describes a study that examined the effect of computer programing experience on the mathematical problem solving achievement of high school students. The variables studied are discussed, including gender, ability, socioeconomic status, prior math experience, and access to a home computer, and a path analysis model is explained. (34 references)…
