The purpose of this study is to explore the potential impact of support materials on student spreadsheet skill acquisition. Specifically, this study examines the use of an online spreadsheet simulation tool versus a printed book across two independent student groups. This study hypothesizes that the online spreadsheet simulation tool will have a greater positive impact on student performance than a printed book. Student performance was measured using scores on 10 individual spreadsheet projects and an overall average of these 10 scores. T-tests were used to determine significance since the project scores are independent and means were compared only across two groups. Significant differences were observed between the groups for two of the ten projects, but further research is needed to identify additional factors that may influence these findings.
