Exploring the pros and cons of mechanistic case diagrams for problem-based learning

Area of Science:

• Medical Education
• Pathophysiology
• Systems Biology

Background:

• Mechanistic case diagrams (MCDs) are valuable tools for understanding complex diseases.
• Limited literature exists on the specific methodologies and practical application of MCDs.
• This study explores the in-depth creation of MCDs to identify their benefits and drawbacks.

Purpose of the Study:

• To investigate the advantages and disadvantages of creating detailed mechanistic case diagrams (MCDs).
• To understand student experiences and the depth of learning achieved through MCD creation.
• To provide insights into optimizing the use of MCDs in medical education.

Main Methods:

• Students were provided with guidelines for creating detailed MCDs, covering subcellular to clinical aspects.
• A questionnaire was used to gather student feedback on their experience with MCDs.
• Student-created MCDs were analyzed to assess the depth of understanding and identify patterns.

Main Results:

• Creating well-organized MCDs led to deeper insights and comprehensive disease understanding.
• Students reported high workload and difficulty in identifying disease mechanisms.
• Suggestions for improvement included thorough text review, staff guidance on mechanism depth, and collaborative work.

Conclusions:

• Detailed MCD tasks promote in-depth knowledge acquisition in disease processes.
• The benefits of detailed MCDs must be weighed against increased workload and potential difficulties.
• Preparation of support plans and allowance for diverse map representations are crucial for effective MCD implementation.
