Computer-assisted instruction in mathematics: Determining the volume of three-dimensional figures.

摘要

This study is a field-test of Computer Assisted Instruction (CAI) in geometry. The CAI was written using Director 8.5 and the subjects were eighth grade general math students from a heterogeneous group from Palos Verdes Intermediate School. The purpose of this CAI was to teach an in-depth, unique lesson of finding the volume of three-dimensional figures. This paper discusses the results and significance of a field-tested CAI program as a means of delivery of instruction. Students responded to an interactive lesson, with remediation, that culminated in a real-world example of the benefits of understanding volume of three-dimensional figures. The pre- and post-test evaluation provided the assessment tool, and the results indicate that this tutorial was valuable in helping students learn how to determine volume of three-dimensional figures.
