A comparative assessment of interactive videodisc instruction

Area of Science:

• Nursing Education
• Medical Simulation
• Instructional Technology

Background:

• Traditional lectures are a cornerstone of nursing education.
• Interactive videodisc (IVD) technology offers a novel approach to skills training.
• Evaluating the comparative effectiveness of different instructional methods is crucial for optimizing learning outcomes.

Purpose of the Study:

• To compare the effectiveness of interactive videodisc (IVD) versus traditional lecture-based instruction.
• To assess the impact of these methods on student knowledge and self-efficacy in intravenous therapy.
• To determine the optimal sequence for combining IVD and traditional instruction.

Main Methods:

• A counter-balanced, randomized design was employed.
• Students received pretests, post-tests after each instructional method, and a final post-test.
• Knowledge and self-efficacy were measured for intravenous therapy procedures.

Main Results:

• Both IVD and traditional lectures significantly improved student knowledge and self-efficacy over baseline.
• Neither instructional method was definitively superior when used in isolation.
• Combining both methods, irrespective of the order, led to sustained or improved scores.
• A sequence of traditional lecture followed by IVD instruction resulted in the greatest increase in self-efficacy.

Conclusions:

• Integrated instructional approaches combining traditional lectures and IVD technology are beneficial for nursing education.
• The sequence of instruction can influence the development of practical skills and confidence.
• Further research should explore the long-term retention and application of skills learned through combined methods.
