The purpose of this action research study was to determine if homework completion had an effect on how students performed on summative assessments. This action research study was conducted in a high school classroom in Northwest Iowa. An Algebra and Algebra 2 class were used during this research process. Quantitative data was collected on homework completion and summative assessment scores for three consecutive chapters covered in each respective class. The results of this study showed while there is a positive correlation between the two variables, no significant conclusions could be made from the collected data.
