Summary

Accommodation

Participants computed math problems either with pencil-and-paper or with a calculator.

Participants

Participants were six adolescents with cognitive/intellectual disabilities.

Dependent Variable

The dependent variable was scores on verbally administered practical addition problems in interval 1, and addition and subtraction problems in interval 2.

Findings

Participants completing problems without calculators in interval 1 who switched to calculators in interval 2 increased accuracy and speed of performance in the calculator condition. Participants who had no calculator in both intervals showed deterioration in performance in interval 2. The researchers concluded that calculator use for adolescents with cognitive/intellectual disabilities can improve the efficiency and accuracy of their performance. Limitations are discussed.
