Tested was the hypothesis that science instruction based on task analysis will lead to the acquisition of the ability to perform certain Piaget volume tasks which have been characterized as requiring formal operations for their solutions. A Test on Formal Operations and a Learning Hierarchies Test were given to fourth- and sixth-grade students in…

Describes a study which used fourth and sixth grade children who had used Science - A Process Approach" and compared their performance with that of a control group on two conservation-of-volume tasks. Performance of the volume tasks was found to be related to age and score on the Learning Hierarchies Test and not to previous science program…

Examination of the learning situation might suggest that if students are exposed to situations focusing on inquiry and student involvement, certain changes should occur in student cognitive and affective behaviors as a result of interacting with the strategies of inquiry of a curriculum. From the curriculum materials of "Science - A Process…

This review presents a broad perspective of the state of knowledge in science education, a description of existing trends, the areas where research is needed, and tentative answers to persistent problems that have been identified from the research. The review is organized into eight sections. An introductory section describes methods of using…
