extensive use of pressure-enthalpy(P-h) diagrams that enable intuitive visualization of even the most complex steam power plantsto a high degree of accuracy. This is contrary to all current thermodynamic textbooks in whichtemperature-entropy (T-s) diagrams are used to represent steam power plants. This standardtextbook approach is non-intuitive in that there is no indication of the turbine power output, andincorrect in that the ideal feedwater pump process is always represented by a line when in fact itshould be closer to a single point.Another significant departure from traditional thermodynamic texts is the use of the ideal Stirlingcycle machine to represent the ideal reversible machine. The ideal Stirling cycle machine has athermal efficiency

areas such as space and human body. A challenge facing TEGs is their low efficiencydue to obtaining their energy from low energy sources such as waste heat and a low figure ofmerit (ZT) that enable conversion of heat into electricity1. , where T is the absolutetemperature, s is Seebeck coefficient, is electrical conductivity, and k is thermal conductivity.In power generation, the Seebeck effect enables the direct conversion between heat and electricenergy streams. Heating one end of the unit cell while holding the other end cooler induceselectromotive force within the material and may be harnessed for electrical power2. In Figure 1,two dissimilar semiconductors A and B are connected electrically in series but thermally inparallel with

defined self-regulated learningas “learning that results from students‟ self-generated thoughts and behaviors that aresystematically oriented toward the attainment of their learning goals” (p. 125). In addition,Bandura9 showed that self-efficacy beliefs impact performance because these beliefs representpeople‟s perception of their capabilities to perform a task at designated levels. These researchershave provided empirical data on causal or correlational relationships between self-efficacy andepistemic beliefs and self-regulated behaviors and performance in subjects such as mathematics5,10 .During problem solving, students assess the difficulty of the task while disambiguating theimportant from irrelevant information.

is a relatively new approach inAmerican universities, generally observed since the late 1980’s, though in other parts of theworld such as Europe, the first engineering degree has always required a minimum of five yearsof study and been considered equivalent to the MS degree.These BS/MS programs vary in their details at different academic institutions. For the most part,they offer the qualified student: 1) the possibility to earn their BS and MS degrees in less time than it would take to pursue both degrees separately, and 2) the opportunity to deepen and diversify their technical and professional skills, which will help make them more competitive and marketable in the global marketplace.As BS/MS programs grew more popular

, teams are formed, with the number of students in each team being decided by thetechnical advisor(s), the course coordinator, and any sponsor(s) in function of the expectationsfor the project. Most of the teams have three students, and students’ preferences have shifted inthe past years from having more interest on internal projects (i.e., no industry involvement) tohaving projects where an industry sponsor is involved. Among the many benefits andresponsibilities that industry sponsored projects provide, one specific benefit is the opportunityto emphasize to the students that engineering design is more than just doing the calculations thatwere typically done in the classroom.Faculty members need to search and request projects from their network

Overall, the course syllabus and the course objectives are met toa great extent. As mentioned before, several assessment tools have been identified such as classwork/homework, quizzes/exams and projects. Sincere attempt is made to refer to the CLOs whiledesigning the contents of the assessment tools used. For example, many class work andhomework problems, and each exam question clearly stated the concept being tested in thatquestion, and to what extent that question addresses the CLO(s) and how it maps the PO(s).Students were informed where this information will be used.

However,after designing and performing the experiment, the juniors liked the assignment less. Theirpositive attitudes decreased to match the freshmen. The junior and senior attitudes were similarbefore designing the experiment. However, unlike the juniors, the seniors became more positiveafter the assignment was complete.The unexpected effects of the experimental design experience that occurred with the juniorstudents are of interest. The juniors initially felt they understood how to design an experimentbut after performing it, they did not. On the pre-survey, 95% felt

The students assembled critical functionprototypes of their fourbar designs as part of a lab exercise, and then manufactured fourbars on awaterjet cutter for their competition robots. Lastly, two of 28 Excel® problems were related tofourbars: one in which the students analyzed S + L ?

Therefore more guidelines have been provided on how to select an appropriate component for the project that addresses all CLOs. Where necessary, an engineering component has been selected for them to work on.As a side note to this, few students always creatively think of a common project topic thataddresses different aspects and requirements to satisfy another course(s) they take during thesame term, for example, a senior capstone design course or another ME elective course such asfailure considerations in design or failure analysis courses.
