Facilitative Teaching Utilizing Active Learning Modules in Engineering Graphics: A Model for Promoting Success and Engagement in Technology and Engineering Education

Abstract

Success in post-secondary engineering graphics courses in technology andengineering often relies on self-efficacy, academic success, and mental rotationabilities. Using a facilitative instructor model, the Improving UndergraduateSTEM Education (IUSE) team applied active learning modules as supplementalmaterial at two post-secondary institutions in the United States of America, thenused a quasi-experimental design iterative study approach to investigate impactsin an introductory engineering graphics course. Active learning modules werecomposed of ten units that engaged students through relatable examples andpractices of foundational principles and applications of engineering graphics thatare heavily applicable to the Standards for Technological and EngineeringLiteracy. The modules were presented to students through an online learningmanagement system that encouraged elements of self-regulated learning.Measurements of self-efficacy, mental rotation ability, and academic successwere gathered. Differences in academic and non-academic indicators wereexamined in combination with students at risk of non-matriculation and studentsnot at risk of non-matriculation subgroups. Results from paired t-tests supportedprevious findings that there are positive impacts of supplemental materialsavailable to students. Students at risk of non-matriculation benefited from thecombination of active learning modules and supplementary video tutorialsresulting in greater self-efficacy and higher final exam scores than at-riskstudents whose modules did not include video tutorials. Students not at risk ofnon-matriculation had higher levels of self-efficacy and mental rotation abilitywhen video tutorials were not included. With this information, engineering,engineering education, and other STEM programs can model elements of activelearning modules to promote early student success in both subgroups.Furthermore, the IUSE team has published the material through open access foreducators and students to utilize.
