A computer-based, problem-solving system of instruction in clinical pharmacology

Area of Science:

• Medical Education
• Clinical Pharmacology
• Biomedical Engineering

Background:

• Traditional laboratory classes in clinical pharmacology are being supplemented by advances in microcomputer technology.
• New interfaces allow real-time display of physiologic data, transforming computers into interactive learning tools.

Purpose of the Study:

• To describe a HyperCard-driven program for problem-based learning (PBL) in clinical pharmacology.
• To enhance students' understanding of electrocardiography (ECG) and cardiac arrhythmia management through interactive exercises.

Main Methods:

• Development of a HyperCard-based program featuring four problem-oriented laboratory exercises.
• Exercises involve interpreting ECGs before and after drug-induced changes in cardiac conduction and rhythm.
• Utilizing computer-based simulations to mimic clinical scenarios.

Main Results:

• The program effectively reinforces problem-solving skills in basic electrocardiography.
• Students gain a better understanding of the electrophysiologic basis for managing cardiac arrhythmias.
• The approach aligns with criteria for successful medical education program evaluation.

Conclusions:

• Microcomputer-based PBL, particularly with interactive ECG analysis, is a valuable tool for clinical pharmacology education.
• This innovative method enhances learning by connecting prior knowledge with new information and future practice.
• Recommended for medical students and allied health sciences professionals seeking to improve cardiac arrhythmia management skills.
