Showed that Piagetian measures of formal reasoning ability are significantly related to achievement, aptitude, and knowledge of the processes of science in a sample of college freshman and sophomore elementary education majors. (MLH)

Secondary science students were tested, using Piagetian tasks to determine their level of intellectual development, and then tested on scientific concepts classified as concrete or formal. Results showed significant multiple correlations between the scores on the tasks and the subject matter tests. (MLH)

Studied the intellectual differences between third and fourth grade Filipino children who had studied Science--A Process Approach (SAPA) and others who had studied a traditional curriculum. The SAPA children performed significantly better than the control group on a test of observing, comparing, and classifying simple geometric objects. (MLH)

Comments on a recent article by DeLuca on electronic "measurement of logical thinking" questioning four aspects of the article. DeLuca responds to the criticism on those four aspects in question. (GA)

The third-year evaluation results of an investigation extending through grade six. Studied performance of the same population, appearing in two previous evaluations, with sex, socioeconomic status, and maturity taken into account. Indicated third grade Science Curriculum Improvement Study (SCIS) children were superior to non-SCIS controls in both…

The goal of the study is to describe the development and validation of a cognitive development test. The test fulfills the criteria of (1) logical equivalence of test items and the mental logic of Piagetian tasks; (2) reliability and validity of the group measure; and (3) efficient, objective assessment.

Designs a testing situation to examine the presence of combinatorial analysis, to establish construct validity in the use of an instrument, Combinatorial Analysis Behavior Observation Scheme (CABOS), and to investigate the presence of the schema in young adolescents. (Author/GA)

Studied performance of 15 low-socio-economic-status 14 year olds in learning controlled-experiment design and evaluation, and indicated that experimental subjects significantly outperformed matched controls. (CC)

Two years after the end of a two-year intervention program set within the context of science learning intended to promote formal operational thinking, achievement of students (n=234) was tested by their results on British National examinations taken at age 16. Male experimental subjects achieved an average of 40 percent more grades of C or above…

Analyzes the performance of the Electronic Task (ET), to test for combinatorial reasoning, over a broad range of subject ages and abilities in order to evaluate it as a substitute for the original Chemical Task (CT). (GA)
