Computer-assisted instruction in orthopedic biomechanics.

Area of Science:

• Orthopedics
• Medical Education
• Biotechnology

Background:

• Orthopedic residents require specialized biomechanics knowledge for board certification.
• Traditional study methods may not fully address the complexities of biomechanics.
• The Objective In-service Training Examination (OITE) assesses biomechanics competency.

Purpose of the Study:

• To evaluate the effectiveness of a computer-aided instructional (CAI) course in biomechanics.
• To determine if CAI improves orthopedic residents' performance on the OITE.
• To assess the efficiency of CAI as an educational tool for orthopedists.

Main Methods:

• Development of a 6-hour CAI course in biomechanics using Basic language on an IBM PC.
• Interactive color graphics and chapter quizzes were incorporated into the CAI program.
• A study group of six residents used the CAI, while nine residents served as a control group.
• Comparison of OITE scores between users and non-users, and pre- and post-intervention.

Main Results:

• No significant difference in outside reading or study habits between groups.
• No statistical difference in 1983 OITE scores between the CAI users and non-users.
• CAI users demonstrated a statistically significant improvement in 1984 OITE scores compared to the previous year (p < .05).
• Non-users showed no statistical change in scores from 1983 to 1984.

Conclusions:

• Properly developed computer-aided instruction (CAI) is an effective and efficient educational method for orthopedists.
• CAI can lead to significant improvements in biomechanics knowledge and examination performance.
• This technology offers a valuable supplement to traditional learning for specialized medical fields.
