Active learning in the lecture theatre using 3D printed objects.

Area of Science:

• Biochemistry
• Biophysics
• Biotechnology

Background:

• Understanding biological molecule structure is crucial for comprehending biological processes and molecular function.
• Traditional visualization methods like 2D slides and videos have limitations in conveying complex 3D molecular structures.
• Active learning strategies can improve student engagement and comprehension in large lecture settings.

Purpose of the Study:

• To investigate the effectiveness of 3D printed biological molecule models as active learning tools in biochemistry education.
• To assess the impact of using tangible molecular models on student engagement and visualization of complex biological structures.
• To explore the integration of 3D models into cooperative learning strategies for enhanced problem-solving.

Main Methods:

• Utilized 3D printed models of biological molecules (e.g., enzymes, DNA) as tactile learning aids in large group lectures.
• Implemented a teaching approach combining foundational knowledge delivery with hands-on model manipulation and a "Think-Pair-Share" cooperative learning strategy.
• Shifted learning from purely cognitive to experiential by incorporating physical objects into the teaching methodology.

Main Results:

• Students demonstrated improved ability to visualize complex 3D biological molecules through hands-on interaction with the models.
• The use of 3D printed models led to increased student engagement and positive participation during lectures.
• Handling physical models facilitated a deeper appreciation of molecular features, such as enzyme active sites and DNA grooves.

Conclusions:

• 3D printed biological molecule models serve as effective active learning tools that enhance student comprehension and engagement in biochemistry.
• Integrating physical models into teaching promotes experiential learning, moving beyond abstract concepts to tangible understanding.
• This approach fosters interactive and challenging learning environments, enabling students to better grasp intricate molecular structures and their functions.
