Evaluations of Adinkra Computing in the Classroom
In 2014 we worked with a middle school in Kumasi, Ghana to conduct a controlled study. We randomly assigned students to one of two groups. The intervention group used the Adinkra Computing software to reinforce the mathematics lesson based on the Adinkra symbols. The control group had similar lessons but without any cultural content, using the GeoGebra software to draw abstract shapes. Both groups began with a pretest and ended with a post test. The pretest and posttests formed the independent samples for a t-test. The results showed a significant advantage for the scores for the Adinkra computing based lesson (M = 45.22, SD = 18.67) in comparison to the GeoGebra computing based lesson (M = 13.87, SD = 15.93); the difference was statistically significant at the .001 confidence level. Another striking difference was that students in the intervention group asked if they could stay after school and continue working on their designs.
