as thick (reducing the bending stiffnesses by a factor of 8).4. Development of a Concept InventoryIn order to assess the effect of introducing the experimental platform on student learning in theStrength of Materials class, a short set of 10 questions were developed to be used as a pre andpost assessment of the intervention. The questions were carefully written to target students’misconceptions about the role of material properties, loading characteristics, and geometry inbeam bending stress and strain. The 10 questions are included as Appendix A of this paper.Referring to the three conceptual goals stated in the introduction, it is seen that questions 2, 4,and 5 relate strongly to concept C1, while questions 3 and 6 strongly relate to
