Thelast part of the project that challenged the students to reflect on their own learning and the wayfuture students may learn the concepts. The reflection component may not be present in typicalprojects, and/or may not be probed. The learning of the students was probed via a survey of afew questions. The questions asked the students if the project increased their understanding ofthe technical concept they

Lifelong learning.The basic premise is that an individual learner must actively "build" knowledge and skills 3. Weknow that technology changes with time and an engineer must be motivated to continue to learnand stay current with technology. Constructivism is a method of teaching and learning based onthe principle that cognition (learning) is the result of mental construction, and this construction inquite individual. Knowledge is formed by reflecting on our experiences, by putting informationtogether with what we already thereby we construct knowledge in our head. Thus, we create ourown understanding of the world we live in. Learning is the process of adjusting our mentalmodels to fit with new experiences. Constructivist theorists maintain that

Therefore, it appears that the commercial software applications had moreutility in problem solving.Genik and Somerton1 describe their work in a senior level capstone course in thermalengineering. "Among the topics covered were power system analysis, refrigeration systems,psychrometrics, combustion, heat exchangers, and numerical conduction. Though the list oftopics may seem to be a hodgepodge, it is somewhat reflective of the eclectic nature ofengineering." To combat the perception of this "hodgepodge" of subjects they designed a set

Some students still do not get a good understanding of the material, but their grade now accurately reflects this fact.Another faculty member’s course assessment revealed that at least three quarters of students inher course achieved the course objectives and close to 100% of students demonstrated theabilities in formulating and solving engineering problems and in utilizing modern tools andskills. That was a substantial improvement over the previous years’ results.

As this isbelieved to be reflective of the product being assembled by the students, rather than the unit conceptitself, product changes are being considered for future sessions. With regard to the lecture portionof the unit, the instructors are still concerned that the students are being introduced to modernmanufacturing via multimedia sources rather than industrial tours. While this approach does freeup an additional day for an alternative topic (such as electromechanical systems), it comes at theexpense of a ‘real world’ engineering experience. If local factory tours were to become accessibleagain, the instructors would strongly consider resuming the old manufacturing curriculum.52.7 Lesson VII: Energy and
