Performance with Graphic Organizers - Case 2/Mathematics

The performance with graphic organizers by case 2, as shown by Table 5, was high for Mathematics. Case 1 averages 100% correct responses with graphic organizers, 100% correct in building connections among ideas, 100 % correct in integrating new information, and 100% independence. After the initial directions were provided, the student was able to complete 44 activities without any cues or prompts.
