Policy documents in science education suggest that even at the earliest years of formal schooling, students are capable of constructing scientific explanations about focal content. Nonetheless, few research studies provide insights into how to effectively provide scaffolds appropriate for late elementary-age students' fruitful creation of…

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)

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…

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)

Investigated the development of formal reasoning among students (ages 10-18 years) from predominately White, middle-class communities located in rural, suburban homogeneous, and suburban heterogeneous areas. Results indicate clear differences among communities in formal reasoning ability. Implications for using science instruction to promote…

Describes a set of Science Reasoning Tasks which are valid and reliable for assessing the ability of children to use concrete and formal reasoning strategies and can be used by science teachers without professional training in Piagetian studies. Thirty pupils can be tested on each task in about 50 minutes. (Author/DS)

Reexamined Piagetian stages of males (N=182) and females (N=176), ages nine to eighteen, using cluster analysis, and sought information concerning occurrence of stages and influence of different tasks and gender on cluster patterns. Findings, among others, indicate that deviation from Piagetian stages was influenced by gender and type of task.…
