Sixty-seven students participated in a study that used path analysis techniques to test a hypothesized structural model of direct and indirect causal effects of students variables on science process skills. Academic ability, biology knowledge, and language preference were found to have significant direct effect, whereas cognitive development,…

Provides evidence to support the conclusion that relationships exist among Piagetian levels of intellectual development, intelligence quotient, content achievement, and inquiry skills in ninth and tenth grade biology students (N=92). (DS)

Data from the 1983-84 Israeli IEA (International Association for the Evaluation of Education Achievement) science study were used to explore gender-related differences (and their determinants) in the learning of science. The study (n=1974) involved several measures of science learning, 10 attitudinal measures, and items and errors classification.…

Examined effects of operational levels of ninth-grade (N=16) and college (N=40) students on causal explanations they recalled after instruction. Results indicate concrete/formal students recalled explanations requiring chaining of two implication statements while formal subjects outperformed concrete subjects in reconstruction of complex…

Purposes of this study were to (1) develop an instrument requiring several classification activities; (2) investigate the correlation between classification ability and intelligence scores of junior high school students (N=365); and (3) determine if classification ability differs with age and gender. Findings included a significant correlation…

Determined if certain variations in the format of Inhelder and Piaget's Equilibrium in the Balance task have any effect on how students (175 undergraduate and 32 ninth graders) are classified. Suggests that researchers allow subjects to experiment with the apparatus to insure proper classification of stage of development. (Author/DS)
