The purpose of this quasi-experimental study was to determine if using Khan Academy as math remediation for fifteen minutes per day during a ninth grade Math I class would significantly affect student math achievement as measured by the North Carolina READY Math I End-of-Course Assessment. This quantitative study conducted at two rural high schools in West Virginia used remediation theory to make a comparison against a control population with the independent variable being grade level instruction only or grade level instruction plus math remediation using Khan Academy. The participants in the study included 131 ninth grade high school students taking a Math I class in a traditional classroom setting between October 2016 and May of 2017. The researcher collected data from students’ pretest and posttest scores on the North Carolina READY Math I End-of-Course Assessment. The original intent was to use analysis of covariance (ANCOVA) to reduce the effects of any initial group differences. However, the data failed to pass the assumptions necessary for ANCOVA or t-test. So, a nonparametric test, Mann-Whitney U, was used in the analysis. There was no significant difference in the posttest scores of ninth grade Math I students receiving regular instruction only and those receiving regular instruction along with Khan Academy for math remediation. Suggestions for further research are included.
