Conceptually Based Development of Individualized Materials for Critical Thinking Based on Logical Inference.
Lowerre, George Fitzgerald
This study developed prototype diagnostic and teaching materials to test logical reasoning ability in second, third, and fourth grade pupils. The testing procedure attempted to find the most difficult levels, along several dimensions, at which a child can use a logical rule. The materials dealt with the rule for "or" elimination and the rule for "all" elimination. Two dimensions were varied: complexity of context and availability of premises in message. Experimental subjects worked individually, using instructional workbooks and tapes, receiving posttests after instruction on the corresponding rule, while control subjects received both posttests approximately eight weeks after the pretests. The change in performance was calculated for each subject on each rule by adding the changes in levels along both dimensions tested. Significant differences were found (in favor of the experimental group) for both the logical rules tested, though the difference for the "or" elimination rules was not as great as the "all" elimination rules. Further development using these procedures is recommended. (Author/DI)
