A Comparison of Three Instructional Approaches Using Manipulative Devices in Third Grade Mathematics.
Gilbert, Robert Kennedy
This study investigated the relative effectiveness of three methods of using manipulative materials for instructing third-grade students on addition and subtraction of two-digit numbers. Subjects (N=124) were selected from a larger pool from two schools on the basis of scores on a prerequisite skills measure and the pretest. They were randomly assigned to one of three treatment groups: Demonstration (D), in which students observe and advise the teacher demonstrating use of the manipulative devices, Individual (I), in which each student works with his own set of materials, and Group (G), in which groups of four or five work together sharing the devices. During the treatments three devices were used: counting straws, counters with place value sheets, and abaci. Identical pretests and posttests were used. Data were submitted to a factorial analysis of variance (school x ability x treatment). Results indicated an interaction between school and treatment, with Treatment I being significantly more effective at one school than D or G; at the other school no differential treatment effects were found. Within ability levels no effect was discovered for treatments. (Author/SD)
