In recent studies, several structural variables have accounted for a good portion of the score variances on verbal problem solving tests. This study investigated changes in the variance accounted by structural variables on problem solving tests when subjects were given instruction to overcome the structural variable influence. Effects on subjects' verbal problem solving ability were also studied. The subjects were 150 college students enrolled in an elementary mathematics education course. Based on a pretest, subjects were divided into three groups of equal ability. An experimental group received instruction and practice problems on the specific variables, as well as supplementary problem solving material. A practice control group received the same practice problems and supplementary materials, but did not receive the problem solving instruction. A second control group received only the tests. Three additional tests were given over the three-week experimental period. The results showed the experimental group made significantly higher scores on all three tests. The amount of variance accounted for by each structural variable remained consistent. (JP)
