Figure 4 showshow the average score on the Tensile Test Lab for all the sections in the Spring of 2020compared to the historical average, and Figure 5 shows the results for the overall grade in theclass. From Figure 4, the sections in the Spring of 2020 performed slightly better on the TensileTest Lab than 2019’s course averages, and yet from Figure 5, the final grade in the course wasslightly lower than the historical averages. This may be due to the transition
the DCIThe idea for a DCI began at a Mini-Conference on Undergraduate Education in Dynamics,Vibrations, and Strength of Materials that occurred in September 2002 [1]. The Force ConceptInventory (FCI) had been around since the early 1990’s and was recognized as beingsuccessful in spurring innovation in physics education [2]. At this meeting, participants agreedthat a Dynamics Concept Inventory could potentially provide the same benefits for dynamicsinstruction. A DCI team was formed and first met at the Concept Inventory Workshop at the2002 Frontiers in Education Conference in Boston (November 2002). The NSF-fundedFoundation Coalition was a key driver behind the development of the DCI and other conceptinventories.The DCI was developed using a

storage in a freezer wasrecommended. An alternative is to use wet-resin layup, where the liquid resin and hardener aremixed just prior to use and added to the dry fibers with paint brushes and rollers. This process isquite messy and time-consuming. For several years, specimens for the class were made as largepanels from prepreg materials and then cut into individual specimens with an abrasive saw. Thismethod was also time-consuming and did not involve the students in the fabrication process.The development of “out of autoclave” prepreg materials as a cost-saving measure in aerospaceapplications has been ongoing since the mid-1990’s [5]. As a result of these efforts, reasonablypriced small quantities of high-quality prepregs that can be oven-cured
