Home Improvement: Calculating perimeter using computer assisted instruction

This study explores the use of computer-assisted instruction (CAI) in the fourth grade math classroom and whether Home Improvement, a program on perimeter developed by the researcher, can significantly raise knowledge levels in elementary school students. California state testing scores indicate room for improvement in mathematics scores and gains in test scores can be achieved with the implementation of CAI supplemental math programs, combined with traditional teaching methods. The research involved a quantitative study using 25 convenience sampled students from one fourth grade classroom. A one-group pretest and post-test design was utilized to evaluate the students' learning. The data analysis consisted of a statistical t-test with related samples looking for significant statistical differences between the pre-test and post-test scores. Results from the study indicated a significant increase in student's post-test scores. Also, the students' view on using the software was positive, and information was gathered on possible improvements on the software.
