Evolution of a student model-building program

Area of Science:

• Physiology
• Educational Technology
• Systems Biology

Background:

• The baroreceptor reflex is a complex physiological control system crucial for maintaining blood pressure.
• Traditional teaching methods often struggle to convey the dynamic and interactive nature of this reflex.
• A need exists for accessible tools that cater to diverse student backgrounds.

Purpose of the Study:

• To design and develop an interactive model-building program for understanding the baroreceptor reflex.
• To provide a visual and structural framework for students to explore physiological control systems.
• To enhance learning across various disciplines and academic levels.

Main Methods:

• Students collaboratively construct simplified models of the baroreceptor reflex control system.
• The program allows for the gradual addition of complexity to the models.
• Audit trail data, surveys, and observations were used to assess and refine the program's effectiveness over three years.

Main Results:

• The program successfully provides a visual representation of the baroreceptor reflex, aiding comprehension.
• Student engagement and understanding of complex control systems were enhanced through model building.
• Iterative improvements based on user data increased the program's pedagogical effectiveness.

Conclusions:

• Interactive model-building is an effective pedagogical approach for teaching complex physiological concepts like the baroreceptor reflex.
• The developed program offers a versatile and visually intuitive platform for diverse learners.
• Continuous evaluation and refinement are key to optimizing educational technology for student learning.
