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.
