Performance with Graphic Organizers - Case 5/Mathematics

The performance with graphic organizers by case 5, as shown by Table 8, was high for Mathematics. Case 5 averages between 90- 100% correct responses with graphic organizers, 90-95% correct in building connections among ideas, 90-95 % correct in integrating new information, and 85-95% independence. Case 5 averages 85 % independence because after the initial directions were provided, the student seldom requires verbal cues or prompts to complete 31activities. Case 5 made minor mistakes such as computation, mixing signs +, - when simplifying expressions).
