Student self-reported enjoyment of laboratory activities. Students completed a survey after completing the lab activities and post-tests. They rated four statements about enjoying the lab on a scale of 1 (completely false) to 6 (completely true); their ratings across the four statements were averaged to calculate their overall enjoyment rating. Centerlines show the medians; box limits indicate the 25th and 75th percentiles; whiskers extend to the minimum and maximum values. Means are indicated by + symbol. Higher scores indicate higher reported levels of enjoyment. Students in the physical treatment reported significantly higher enjoyment
