Abstract
The present study evaluates the effectiveness of three instructional methods, labeled Examples, Graph, and Discovery, for improving students' estimates of mixture problems. The problems involved mixing various quantities of acid and water solutions. The student's task was to estimate the percentage of acid in the resultant mixture. Although none of the three methods caused a significant change in estimation accuracy, the results were in the predicted direction, suggesting that the methods may become more effective with improvements. The results also revealed a significant difference between males' and females' overall performances. Further analysis suggested that this difference may reflect differential understanding of the underlying concepts on which the problems were based. Suggestions for improving the present instructional methods are made, as well as alternative approaches for improving students' estimates.
