Computer-Assisted Instruction for Introductory Genetics

Abstract

Computer-assisted instruction (CAI) offers a valuable supplemental teaching aid for courses that require repetitious drill to develop problem-solving skills. Computer assisted genetics instructor (CAGI) help students and teacher identify weaknesses and misconceptions, provides interactive drill to encourage students to master problem-solving, and reduces the need for continuing teacher tutorial time. CAGI contains multiple-choice questions developed by the course instructor and immediately acknowledges correct responses. The performance of students using CAGI was evaluated in an introductory genetics course comprised of students from several majors. Students utilizing CAGI scored an average of between 6 and 10 points higher on hour exams than students in the same class who did not use CAGI. More than 96% of CAGI users received a grade of B (88 percentage points) or better; 67% of the nonusers received B or better. CAGI helps students focus on the key aspects of biological processes, diagnose misconceptions, and provides drill accompanied by immediate feedback.
