Validity Considerations for the Study of Formal Reasoning Ability and Integrated Science Process Skills.
Baird, Willam E.; Borich, Gary D.
Recently, a number of studies have reported a high correlation between the supposedly separate traits described as integrated science process skills and formal reasoning ability. The implication has been that these two constructs are different but related. Further implications have been made that a treatment to enhance one "trait" might influence the other as a result of some cause-effect relationship. This study measured these two attributes using different instruments to assess their discriminant and convergent validity. The instruments used were the Classroom Test of Formal Operations (Lawson) and the Group Assessment of Logical Thinking (GALT) to measure formal reasoning, the Test of Integrated Process Skills (TIPS II) and the Process Skills of Science Test (PSS) to measure integrated science process skills. Results indicate that the two traits share more variance than expected and that they may not comprise distinctly different traits. A factor analysis was performed on subtest intercorrelations to examine which, if any, subfactors on the two constructs overlapped. Overlap was indicated for the subfactors of controlling variables, probabilistic reasoning, and combinatorial reasoning. (Author/JN)
