An interactive computer lab of the galvanic cell for students in biochemistry

Area of Science:

• Chemistry Education
• Physical Chemistry
• Computational Chemistry

Background:

• Traditional chemistry courses often present challenges in visualizing and understanding abstract thermodynamic concepts.
• Experimental labs provide direct measurements, but calculating thermodynamic quantities like Gibbs Free Energy (Δ_r G), Enthalpy (Δ_r H), and Entropy (Δ_r S) can be difficult for students.
• Integrating digital tools can bridge the gap between theoretical calculations and experimental observations.

Purpose of the Study:

• To introduce an interactive module for teaching fundamental electrochemistry and thermodynamics to undergraduate natural science students.
• To enhance student comprehension of calculated thermodynamic quantities that are not directly measured in laboratory settings.
• To explore the role of new technologies, including cloud computing, in modernizing chemistry education and improving accessibility.

Main Methods:

• Development and implementation of an interactive module designed for first-year natural science students.
• Integration of the module with existing experimental laboratory components.
• Utilization of cloud computing platforms (e.g., CoCalc) for code distribution and enhanced student collaboration.
• Facilitation of interactive discussions on study questions among students and instructors.

Main Results:

• The interactive module significantly improved students' understanding of key thermodynamic quantities (Δ_r G, Δ_r H, Δ_r S).
• Cloud computing platforms enabled wider access to course materials and interactive tools beyond the classroom.
• Students reported appreciation for the approach, citing enhanced opportunities for collaborative learning and discussion.
• The study identified potential for technology to substitute certain experimental components and increase course accessibility.

Conclusions:

• Interactive digital modules, when combined with experimental work, are effective tools for teaching complex thermodynamic concepts.
• Cloud-based platforms offer a viable solution for distributing computational tools and fostering collaborative learning environments in chemistry education.
• Technological integration in chemistry courses can improve accessibility and student engagement, despite some limitations inherent in cloud computing.
