A Comparison of Different Types of Transparencies for Effective Learning in the Biological Sciences at the College Level.
Odom, Harrell James
The purpose of this study was to determine if freshman biology laboratory classes would experience comparable achievement after being taught by different instructional techniques. Five groups of 18 students were involved in the study. Each group covered the same material, however, five different instructional procedures were used: (1) instruction with use of a chalkboard, (2) instruction using black and white transparencies, (3) instruction using colored transparencies, (4) instruction with transparencies of real photography of specimens, and (5) instruction with overlay transparencies. Pretests and posttests were administered, and a test and analysis of covariance were used to analyze the data. The results indicated no significant differences in learning among the five groups. It was concluded that all five methods were about equally effective, and that color, realistic detail, and sequencing of the material did not significantly improve instructional effectiveness in this study. It was also found that sex differences with regard to learning from the five different techniques were slight. (Author/JR)
