Cognitive Growth through Peer Collaboration, 1985-1986

Experimental Group 1 comprised 40 fourth graders who worked in pairs to solve math problems. Experimental Group 2 comprised 40 children working on spatial problems. There were six weekly training sessions, during which the children were presented with increasingly difficult problems in either the math or spatial reasoning area.

The control group was 42 children who received only the same pretest and post tests as the two experimental groups. In Year 2 (1986), all of the Year 1 children were given a problem in physical equilibrium (Siegler's "balance beam") to work on. They worked in dyads over a six week period.

A new control group of 42 fifth graders who were pretested and posttested on the balance beam problem but who did not participate in the learning sessions was added. Materials used during the peer math sessions were missing addend and multiplication number problems, word problems, ratio problems, and proportion problems. Materials for the spatial reasoning sessions were perspective-taking problems, construction problems, and map-drawing problems.

The six balance scale sessions each consisted of 20 incrementally more difficult problems. The Murray Research Archive holds original record paper data pertaining to pretests/posttests, materials generated by children during the sessions, and transcripts (electronic text files) of sessions 1 and 6 in both years. Numeric file data consists of test scores, coded transcripts, summary interaction codes, and sequential codes.

Holdings also include videotapes of sessions 1, 4, and 6 in Years 1 and 2.
