Science education models for secondary and college students as well as K-12 teachers have been dominated by classroom-based approaches. Recently, research apprenticeships wherein learners worked with practicing scientists on authentic scientific research have become increasingly popular. The purpose of this critical review of the literature was to…

A comparison of the theories of Jean Piaget and William Perry (using individual interviews with college students) shows that the two theories outline different and independent processes for assessing intellectual development. (JN)

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)

Effects of external reinforcement and cognitive conflict-based treatments on students' acquisition of ability to control variables at an early age were studied. Smedslund's finding was confirmed. Nearly half of trained students with a mean age of 11.8 years could be classified in late formal operations. (CC)

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…

A sex-related difference, favoring boys, was found on initial performance of two samples (one British, one American) of 10- and 11-year-old children on tasks involving volume and density. After classroom instruction that included opportunities for interaction with appropriate materials, both sexes performed at higher levels but differences…

The paper presents a discussion of a theory of intelligence which postulates that intelligence develops rather than that intelligence is an innate ability possessed in full measure at birth. Discussion of unresolved issues surrounding their theory is presented. The effect of such a theory on science teaching is discussed. (RE)

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. (RE)

Determined that males (N=70) demonstrate higher level of intellectual development than females (N=70), that males mature intellectually earlier than females, and that there appear to be factors other than age and sex that are related to development of formal operational reasoning. Implications of these and other results are discussed. (JN)

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)

Determined if student questioning skills could be taught within framework of an ongoing chemistry course and if acquisition of these skills depends on high school students' (N=108) level of intellectual development. Results indicate that questioning skills can be acquired by students, regardless of their level of Piagetian intellectual…
