Tactile teaching: Exploring protein structure/function using physical models*

Area of Science:

• Biochemistry
• Structural Biology
• Science Education

Background:

• Physical models can be constructed from solved protein atomic coordinates.
• Effective teaching of protein structure and function remains a challenge.
• Current educational methods may not fully convey complex protein dynamics.

Purpose of the Study:

• To review experiences using physical protein models in high school and undergraduate education.
• To explore the utility of physical models in teaching difficult protein structure-function concepts.
• To demonstrate the application of physical models in specific biological examples.

Main Methods:

• Utilizing physical models in professional development for high school biology and chemistry teachers.
• Implementing hands-on physical protein modeling activities in student enrichment programs.
• Applying physical models to illustrate concepts like enzyme active site packing and protein conformational changes.

Main Results:

• Physical models are effective tools for professional development and student enrichment in high school.
• Models aid in communicating complex undergraduate-level concepts, such as enzyme active site structure.
• Physical models successfully illustrate dynamic processes like pH-induced protein conformational changes.

Conclusions:

• Physical protein models offer a valuable, tangible approach to teaching complex biological structures and functions.
• The use of physical models can significantly improve student and teacher comprehension across educational levels.
• Physical modeling represents a promising pedagogical strategy for advancing biological education.
