at all good.Thus, there may have been a significant change in UTA quality between the 2012 and 2013classes. Second, there is a tendency to recalibrate grading metrics based on current information.When students perform better, our expectations for their abilities also rise. Thus, the return tomore traditional grade distribution may be due to a normalization of grades based on theprevious years’ experience.2.3 Department of Chemical EngineeringImplementation of the UTA strand in the Department of Chemical Engineering has focused onthe first three courses students will take within the department, namely Introduction to ChemicalEngineering, Introduction to Materials Science, and Material and Energy Balances. In each ofthese courses, the UTAs
questions used in the new SAM cur-riculum were similar to those from the traditional courses. Comparison of student performanceshowed that SAM students performed as well as or better than traditional students in both multi-ple choice and work-out problems in the area of dynamics. A similar study, but with a smallsample size, was conducted at the University of New Haven in the chemical engineering pro-gram23. The original sequence of two sophomore courses (Fundamentals of Chemical Engineer-ing I and II) focused on material and energy balance applications using a traditional approach.The new curriculum included a SAM course discussed earlier followed by a course that providedmore depth in material and energy balances.
