Investigating Students’ Long-Term Retention of Mohr’s Circle Concepts
Mohr’s Circle is a critical concept for determining failure conditions in the field of geotechnical engineering. Most students struggle to successfully transfer Mohr’s Circle concepts from a Mechanics of Materials course to an introductory geotechnical engineering course. A background knowledge probe (pre-test) of Mohr’s Circle key concepts was developed and administered in an introductory geotechnical engineering course at University “X”. The pre-test was employed to assess students’ prior knowledge of Mohr’s Circle concepts at the beginning of the course. This study examines the pre-test data from sections of Introduction to Geotechnical Engineering taught in fall 2019 and fall 2020 at University “X”.
