In a traditional lab, students conductpreconfigured experiments based on established procedures. They then gather, analyze andinterpret data, and write reports. However, little is done to train engineering graduates to designexperiments for a specific purpose and without a prescribed procedure. Engineeringprofessionals are frequently tasked with designing experiments to demonstrate performance

In fact, an engineering physics program, together with courses, could be viewed as auniversal donor 1. Fundamental concepts are usually covered in introductory engineeringphysics course. However, it was reported in a recent 2005 case study that some 10 to 15% ofsenior engineering students still have confusion about the difference of energy and temperature 2.The finding is consistent with an earlier 2000 report that some students identify movement ofelectricity and energy transfer as material flows, completely

Furthermore, as new technologies continue to progress rapidly and coursecontent and laboratory instrumentation continue to evolve in order to keep pace, laboratorymanuals will also have to be revised frequently in order to stay relevant and effective. A laboratory manual revision process was developed in this study in order to supportthese new types of laboratory classes. It is a four-step process, which includes: 1) CollectingAudience Responses, 2) Scaffolding the Class Project, 3) Project Report Writing Requirementand 4) Peer-Review and Reflection. This development was carried out based upon the technicalwriting framework, as it is believed that technical writing can promote critical thinking andactive learning

progressfrom “cookbook” experiences to somewhat more open ended labs and finally to asignificant experimental design process. In the first series of six straightforward“cookbook” labs, students have one week in which to perform pre-lab work, do theexperiment, and write a short technical report documenting their results. Next, there aretwo somewhat more open ended “two week labs” where students extend the knowledgeand skills obtained earlier in the course to answering slightly more difficult experimentalquestions, with slightly increased reporting requirements. Finally, the last quarter of thesemester is devoted to a four week experimental design laboratory, requiring students toformulate a question, select equipment, construct or modify an apparatus

Project TestingAs part of the final lab report submission process, students were asked to write an opinion ofwhat they learned from the project. The following is a typical response:"It was exciting to be able to get a functional, graduate-level project put together in a span of afew weeks. Especially since the material we learned in the Fundamentals courses played directlyinto the project. In other words, linking frequency domain topics like aliasing to circuittopologies like the Sallen-Key filter made the course come together."Electromagnetic FieldsThe studio model that has been implemented for ECE Fundamentals 1, 2 and 3 at the Universityof Virginia is being adopted by a broader range of courses in the undergraduate curriculum,notably our

, increase the likelihood that they will be better designers. The belief is that athorough understanding of fundamental principles allows a person to perform “mindexperiments” and thereby recognize unique ways to solve problems. Intuition is avaluable asset for a designer and must be cultivated like a skill. By explaining realphenomena using fundamental principles, students will develop their creative skills.Because many students trust their intuition more than lecture materials, it becomesimportant to present the students with something they believe is true yet contradicts theirintuition. The objective is to help students rely on their “intuition” yet show them thatintuition must be developed using their knowledge of fundamental principles. With

transducers to be used to measure the force generated by a rehabilita-tion patient. As the required capacities of load cells for which the students' design method mustbe usable vary from 5 to 100 pounds, a single design is not acceptable; the students must create adesign algorithm. The algorithm is then used to design a single transducer which the studentsbuild, calibrate, and test in the laboratory. The memo (shown in the Appendix of this paper) isdeliberately somewhat vague, imitating the instructions often given to engineers by customers.The students are told that the owner is not an engineer, and therefore the students need to com-municate with the business owner in terms that he or she can understand.

This isespecially true in the electrical engineering technology classroom where the focus is more on a‘hands on’ approach with less mathematical rigor.

A list of components for a possiblecircuit to accomplish this project was also given.

During Lab: PresentationsBesides building the models in the first lab meeting, fundamentals of fluid drag are discussed,since most of the students have not taken fluid dynamics at this point in the curriculum.The second week in the project sequence involves performing a drag test in the wind tunnel. Thewind tunnel used for this experiment is equipped with a built-in force measurement system,allowing the user to read lift force, drag force and wind velocity via a computer interface. Acustom-made cylindrical aluminum bushing was made by the lab technician, the outerdimensions of which are identical to those of a rocket motor. The bushing is drilled out to matchthe size of the wind tunnel bracket used for measuring lift and drag. This
