The Development of New Supplementary Teaching Materials and an Analysis of Their Potential Use in the High School Biology Curriculum.
Duke, Reese Dale
These materials, called "Springboards for Discussion," were designed to fit certain topics in the BSCS Blue Version textbook, "Biological Science: Molecules to Man," and to be presented by teachers using an overhead projector or magnetic audio-tapes, or both. The twelve "Springboards for Discussion" were used in first semester classes in a Houston, Texas, high school, while another Houston high school served as a control group. Data gathered included pretest scores on the Processes of Science Test and the Differential Aptitude Test: Verbal Reasoning and Numerical Ability. Selected items on the BSCS Comprehensive Final Examination and a post-test of the Processes o f Science Test were administered at the end of the semester. The experimental group scored significantly higher on the Processes of Science Test (P = <.01) when scores on the DAT were held constant. The control group scored significantly higher (P = <.05) on the BSCS Comprehensive Final when scores on the DAT were held constant. Teacher feedback agreed with the analysis of the test data. Detailed interpretations of these results are discussed in the report. (BC)
