PSVT-Rot pre-post results for the control group (Table 7): mean 43.7% to 49.5%, F = 10.8, p = 0.002, partial eta-squared 0.135. Control males (F = 6.26, p = 0.017) and control females (F = 4.47, p = 0.042) also gained significantly.

Discussion¶

Learner Variables¶

• Spatial Ability — outcome: instruction changes it
