Increasing Interest, Confidence and Understanding of Ethical Issues in Science through Case-Based Instructional Technology.
Lundeberg, Mary A.; Bergland, Mark; Klyczek, Karen; Mogen, Kim; Johnson, Doug; Harmes, Nina
Software designed to promote the use of open-ended investigations in science education was evaluated in a study of whether using case-based simulation enhances students' understanding of ethical issues and data interpretation in science. The software was a DNA gel electrophoresis simulation that enabled students to conduct simulated genetic tests. Students chose a case with a genetic disease, researched the disease, and presented their test results. Forty-three college students, mostly nonscience majors, participated in the study. To evaluate the impact of the case-based simulations, an interdisciplinary team designed and administered qualitative and quantitative measures assessing students' interest, confidence, understanding of ethical issues, and interpretation of data. Students' understanding of ethical issues associated with genetic testing increased significantly for men in the experimental group. The case-based simulation enhanced interest in biology and confidence in understanding biology, particularly for female students. Four appendixes contain a case example, the student survey of interest and confidence, a case analysis task, and the scoring rubric for the task. (Contains 3 figures and 25 references.) (SLD)
