Abstract :

The role of instruction on improving rate and correctness of addition operation strategies was analysed. Seventy-one first grader boys were randomly assigned to an experimental and a control group. Form A Test of Individual Differences in Children's Addition Strategy Choices (Kerkman & Siegler, 1997) was administered to both groups to assess mean response time and frequency of correct responses. Over a three month period the experimental group received 15 sessions of forty-five minute instruction on retrieval and backup strategies for addition operations. The control group received none. After the instruction period both groups responded to Form B of the aforementioned test. Results of ANOVA demonstrated that the use of backup strategy significantly increased the frequency of accurate responses in the experimental group.
