The Effects of Instruction in Sentential Logic on the Growth of the Logical Thinking Abilities of Junior High School Students.
Braxton, Loretta Murray
The purpose of the study was to determine if instruction in aspects of sentential logic significantly influenced the growth of logical thinking abilities of junior-high-school students. One hundred fifty-seven students enrolled in seventh-, eighth-, and ninth-grade general mathematics classes participated. The Cornell Conditional Reasoning Test was used as pretest and posttest. Results showed a significant difference between mean scores of experimental and control groups on the posttest when pretest scores, age, sex, grade level, intelligence, and socioeconomic level were controlled. Mean scores of the experimental group were significantly higher than those of control groups on the hypothetical syllogism and contrapositive subtests. Age did not appear to be a significant factor for predicting total posttest or subtest scores. The upper intelligence group achieved significantly higher scores on total posttest as well as on the modus ponens, modus tollens, hypothetical syllogism, and contrapositive subtests. The order of difficulty (from least to most difficult) of logical patterns as determined by the scores of the experimental students were: hypothetical syllogism, contrapositive, modus ponens, modus tollens, denying the antecedent and affirming the consequent.
