: Many students answered the three questions, “In what ways was the workforcepresentation instruction useful?” 2) “Is there anything else you would suggest changing?” and3) “Any additional comments?” The answers represented four themes: professionalism,awareness of good communication skills, comments about skills, and appreciation. Some of theanswers are included below. 1) Professionalism---for example, students said a. “It [the instruction] helped to gather a sense of professionalism.” b. “I like this program! I think it will definitely help students with senior design, other campus presentations, and presentations in industry.” 2) Awareness of good communication skills--- a. “Good tips

Since the end-of-semestermeasure of students’ satisfaction turned out to have a non-normal distribution which is alsocharacterized by unequal variances – and by checking the distributions, provided in Appendix B,the distributions did not seem to look similar – there was no reliable statistical test available tocompare the two distributions central tendencies.

The simulation is performed twice: a) with half of the roof shaded with PV modulesmounted on a rack, and b) with no PV modules. Even though the specific device used here toprovide the shading is PV arrays, any other means would produce similar results. The dynamicthermal model of the house is implemented in TK-Solver. The simulation goes through everyhour to determine the required cooling and heating load. It takes into consideration direct anddiffuse solar irradiance. It uses the Sol-Air temperature approach to determine wall and rooftemperatures. This approach modifies the outside skin temperature depending

This powerful teaching technique requires certain premisesof teaching and learning to be put into place.7Fortunately, by applying three fundamental principles, instructors can create theseconditions in the vast majority of learning groups. These principles, referred to as“KEYS” in his essay, are: a) promoting individual and group accountability; b) usingassignments that link and mutually reinforce individual work, group work, and total

Based on these general trends in thefeedback and discussions, actions will be taken to establish a more coherent flow in the lessonand tie together the simulation and synthesis. One way to do this is to implement the applicationcomponent of the lesson, which will require teachers to draw on the information they gleanedfrom experimentation with the quantum dots and the simulation. In this application component,the teachers will create a presentation for a fictional “company” that wants to use quantum dots,explaining a) how they function and b) why they would be useful for this particular application.

The solution concentration of the penetrant is volatile bydesign, and its purpose is twofold, (a) to furnish information about the presence and depth ofdefects by reacting with the indicator, and (b) to vanish from the flaws and make the post-cleaning unnecessary.Examples of experimental results obtained though CDM are presented in Figures 4 and 5.

In this paper we discuss a new approach to teaching problem solving and criticalthinking skills to physics and engineering physics students. We propose a new method in whichphysics students are asked to evaluate different solutions to a given problem and decide why aparticular solution is the correct one compared to various other approaches leading to the exactlysame final answer. This technique could facilitate critical thinking in students taking introductoryphysics courses.IntroductionPhysics is traditionally considered a difficult subject to master because of the high degree ofproblem solving skills demanded in learning the subject.
