Case 2

Grasping the Concept vs Memorizing the Procedure

ADHD:
Strong Global vs Poor Focal Awarenes
Inclined to Explore for himself vs Disinclined to Comply with Prescriptions

Insight into the concept, confusion about formal procedure

126/42 = 88
How many 42's in 126? About 1 and two more (42 + 42 estimated to be 88)

What time will it be 6 1/2 hours after 6:45

6:45
6:30

Adds 45 and 30 to get 75. Says, You canıt go over 60 minutes so youıd have to carry with the 75.
NONVERBAL LEARNING DISABILITY
Fragmentation vs Integration
Achievement vs Understanding

Dedication to Memorized Procedure, Loss of the Concept that justifies it
Blind ³Rule² Following
1.05
x .2
2.30
³2 x 5 is 10, put down the zero, carry the one.
2 x 0 is 2, plus (the carried) one is 3
2 x 1 is 2²
When questioned, S was able to say that 1.05 was about 1, .2 was about 1/2 (this was accepted) and said that 1/2 of 1 would be less than 1. When challenged about his answer that was greater than 1, S answered with greater faith in the algorithm than in the numbers:

³If it doesnıt say 2, then I didnıt show that I got the answer.²
