Analysis of a mammography teaching program based on an affordance design model

Area of Science:

• Medical Education
• Radiology Informatics
• Human-Computer Interaction

Background:

• E-learning is increasingly used in medical education, particularly for mammogram interpretation.
• Existing evaluation methods for e-learning in this field have limitations.
• An affordance design model provides a framework for evaluating e-learning effectiveness.

Purpose of the Study:

• To examine an existing e-learning program for mammogram reading using an affordance design model.
• To assess the program's features, functions, and presentation for educational efficacy.
• To evaluate learner interaction and satisfaction with the e-learning software.

Main Methods:

• A case study approach was employed to analyze the e-learning software.
• Selection criteria included content relevance, representativeness, and accessibility.
• Data were collected through interviews, document analysis, and usability testing.

Main Results:

• The e-learning program (PBE) offers tools for display optimization, image scanning, comparison, region marking, and report construction.
• It includes resources like an image library and term search to aid knowledge construction.
• Users reported positive experiences with navigation, instructional aids, and overall design.

Conclusions:

• The software's cognitive tools support perceptual problem-solving and enhance learners' capabilities in mammogram reading.
• Learners can internalize mental models through features supporting feature sensitization and expert-guided reporting.
• The program's design aligns with learning principles, facilitating skill enrichment and job transfer.
