Abstract
This quasi-experimental research study evaluated two intact undergraduate engineering statics classes at a private
university in Texas. Students in the control group received traditional lecture, readings and homework assignments.
Those in the experimental group also were given access to a complete set of online video lectures and videos
demonstrating how each type of mathematical problem was solved through the learning management system. Overall,
students in the experimental group perceived course material more positively than those in the control group and felt
the additional material was useful. The experimental group had slightly improved cumulative test scores, but these
differences were not statistically significant.

1. Introduction
This study compares the effectiveness of using online supplemental material on a companion Blackboard site to
enhance the face-to-face classroom environment in an undergraduate engineering Statics class. A total of two
undergraduate sections of an engineering statics class was studied during the Fall, 2013 semester; these intact classes
were taught by the same professor. The control group received the traditional lecture in the face-to-face classroom. The
experimental group had supplemental video material available for each week. Both groups took the same final exam
and completed survey instruments.
