From Plastic Models to Virtual Reality Headsets: Enhancing Molecular Structure Education for Undergraduate Students

Area of Science:

• Chemistry Education
• Molecular Structure Visualization
• Educational Technology

Background:

• Traditional molecular models (plastic, plasticine) have limitations in chemistry education.
• Mahidol University International College has progressively adopted new teaching tools over ten years.
• Integrating technology is crucial for modernizing chemistry laboratory instruction.

Purpose of the Study:

• To document the shift in teaching tools for introductory chemistry laboratories.
• To evaluate the effectiveness of augmented reality (AR) and virtual reality (VR) in chemistry education.
• To provide a model for technology integration in secondary and university chemistry classes.

Main Methods:

• Transition from traditional models to computer software, then to AR/VR tools.
• Implementation of MoleculARweb and MolecularWebXR software in laboratory classes.
• Collection and analysis of student survey data to assess outcomes.

Main Results:

• Student surveys indicate the impact of AR and VR tools on learning molecular structures.
• The study details the practical application of specific AR/VR software (MoleculARweb, MolecularWebXR).
• Instructional focus included VSEPR, Atomic Orbitals, Molecular Orbitals, Skeletal Formula, and Enantiomers.

Conclusions:

• AR and VR tools represent a significant advancement over traditional methods for teaching molecular structure.
• The findings offer a practical framework for educators to adopt educational technology.
• This research highlights successful Swiss-Thai scientific collaboration in educational innovation.
