I observe many students frantically cramming before quizzes, stressing themselves out and potentially reducing their academic peformance due to test anxiety. Research shows test anxiety could diminish academic performance. To test if anxiety reducing activities lead to better test performance, I randomly led a anxiety reduction activity with two of my sections (stretching exercises, spontaneous laughter) and did not with three of the others, and compared results (see spreadsheet). Results showed that though the anxiety-reduced groups had slightly higher quiz grades, adjusted for the standard deviation, the two groups were not signficantly different. However, the experience did indicate a way to improve the process for the next time, by providing students resources on how relaxation and laughter can boost academic performance (see full report attached).
