Interactive videodisc learning for radiology is equally effective using bar-code books or computer-assisted instruction. However, most medical students preferred the computer format for its subjective advantages.

Area of Science:

  • Medical Education
  • Radiology Training
  • Instructional Technology

Background:

  • Interactive videodisc technology offers novel approaches to medical education.
  • Evaluating different formats of interactive videodisc learning is crucial for optimizing instructional design.

Purpose of the Study:

  • To compare the instructional effectiveness, time, and student preference between bar-code book and computer-assisted instruction formats of interactive videodisc for radiology learning.

Main Methods:

  • A controlled crossover experimental design was used with 48 fourth-year medical students.
  • Two videodisc modules with identical content were presented in both bar-code book and computer-assisted instruction formats.
  • Pre- and posttests were administered to assess learning gains.

Main Results:

  • Both formats significantly improved student scores from pretest to posttest (p < .01).
  • No significant differences were found in test scores or instruction time between the bar-code book and computer formats.
  • Subjectively, 74% of students preferred computer-assisted instruction over the bar-code book format.

Conclusions:

  • Interactive videodisc learning modules are educationally equivalent in bar-code book and computer-assisted instruction formats.
  • Student preference leans towards computer-assisted instruction, suggesting non-educational factors influence choice.
  • Selection between formats should consider cost and availability alongside educational equivalence.
