From microstructural evidence to research engagement: an analytical transfer and engagement model for sustainable geotechnical education

A research-integrated module in geotechnical education successfully enhanced student competence in interpreting uncertain evidence, connecting microstructure with engineering behavior, and evaluating sustainability-oriented decisions without increasing contact hours. This model demonstrated positive outcomes in theory and laboratory performance for civil engineering students, suggesting a viable approach to integrate advanced analytical and sustainability concepts into existing curricula.

Why it matters

This research demonstrates an effective methodology for curriculum enhancement that addresses critical gaps in traditional STEM education, particularly regarding advanced analytical skills and sustainability considerations. Such pedagogical innovations are vital for preparing future professionals to tackle complex, interdisciplinary challenges in their respective fields.

Key insights

• Traditional geotechnical laboratories often fall short in developing students' interpretative skills, linking microstructure to engineering behavior, and fostering sustainability evaluations.
• A research-integrated module, incorporating conventional soil characterization, chitosan-based stabilization, scanning electron microscopy, and ImageJ-assisted analysis, was evaluated.
• The module was embedded into a regular 'Fundamentals of Geotechnics' course for 50 civil engineering students.
• It offered open-ended engineering explanations and differentiated engagement pathways.
• The integration did not require an increase in contact hours.
• Mean scores indicated strong performance: 83.28 +/- 6.67 for theory and 82.20 +/- 6.28 for laboratory work, 79.10 for undisclosed additional metric.
