5. Conclusion
Overall, the use of supplementary materials in a statics course had no effect on test scores; test scores remained
equitable. The overall mean test score for the experimental group was slightly higher than the control group but this
was not significant. The students in the experimental group were more likely to feel they had the materials they needed
than those in the control group. When students in the experimental group were required to use the videos when lecture
was for this group had to be cancelled and another faculty member was used to teach the control group, those in the
experimental group were just as successful as those who received the lecture material in class as measured by two exam
problems. In this study, the use of supplementary online material was found to be useful to the students who had access
to it. It can be invaluable when lecture must be cancelled because a professor is not available. If this supplementary
material is available, valuable class time need not be lost due to instructor illness. In addition, this material can also be
provided to students who had to miss class due to illness or other obligations to ensure they have access to all needed
materials.
