Developing Critical Thinking: A Useful Instructional Strategy for Promoting In Depth Science Learning.
Zohar, Anat; And Others
This study is an evaluation one phase of the Biology Critical Thinking (BCT) project. Seven skills were selected as goals of the BCT project (for example, isolating variables) and learning activities for these skills were developed. The study compared two groups using the same textbook (n=678 Israeli seventh grade students). The following instruments were used: General Skills Test (GST); the Biological Skills Test (BST); and a Concepts Test of the topic "water balance in living organisms." Cronbach alpha reliability for the GST was 0.62 and for the BST was 0.63. Results indicate there were significant differences between the posttest scores of the two groups for the GST and the BST. The effect sizes were large (E.S.=2.0 and 2.5). (PR)
