A Study of the Effectiveness of Computer-Assisted Instruction in the High School Biology Classroom.
Ybarrondo, Brent A.
This study ascertained whether or not computer assisted instruction (CAI) enhanced the quality of the educational experience and resulted in increased learning. The study involved the teaching of a 3-week instructional unit on population genetics and evolutionary processes to advanced placement biology students. The control group (N=38) received the instructional unit alone while the experimental group (N=39) received CAI experiences in addition to the conventional learning activities. The CAI experiences included a computerized simulation of evolutionary trends resulting from natural selection acting upon a population in lieu of the traditional laboratory, as well as an additional tutorial CAI exercise. Both groups were given the same posttest evaluation exercises and the scores compared with a student's t-test at the .05 level of significance. No significant increase or decrease in test scores was demonstrated at this level. Student evaluations of the CAI lessons presented were very high and indicated considerable interest in continued involvement with CAI. This is consistent with other research findings which indicate that students enjoyed the CAI experience, felt that they had learned from it, and would like to participate in CAI lessons in the future.
