The rubric was used for guidance by the faculty in the final presentation inhelping guide them with grading of the project but it did not prove possible to apply the rubric inthe manner for which it was intended, to provide assessment of the achievement of the individualSE competencies. The result was that a common assessment protocol could not be achieved andconnected to student grading which in the end is the key. This is being addressed in the Phase

to applying entropy to a variety of applications in life ranging from theautomobile to natural disasters to medical applications. The 145 statements wereevaluated based on their correctness. A partially correct answer is one where the effect ofentropy was not completely explained. An example of this is the statement “In weather,precipitation is a form of entropy.” A correct answer would be “In weather, precipitationcreates entropy when it erodes farm soil.”The students in the thermodynamics class were given a different assignment for theiressay (Appendix B).

DfXs are essentially well defined commonengineering problems that an engineer will encounter when working in a specific field. Forexample, DfE highlights what things an engineer must consider when designing in the field ofenvironmentally conscious design. The different stages of a DfX’s development therefore mirrorthe depth to which engineers have considered, or defined, a given problem. We hypothesize thata step-by-step descent through the stages of a DfX’s development would both motivate studentsby exposing them to the history of their discipline, and sensitize them to design
