These changes can affect the students’ first yearexperience, including their performance in the classroom and their desire to stay in school. Theculminations of such experiences are recognized within three major areas of transition:Academic TransitionsThe first transition that many engineering students encounter is within the academic milieu,which is often compounded by the additional challenges these changes elicit. As a studentmoves from high school to college he/she is channeled through the high school highly structureddaily schedule of planned activities. Upon entering college

The goal of thelab is to reinforce the material covered in the classroom and to develop an understanding ofbuilding power system design and effective production and design methods. At the beginning ofthe semester, the class is presented with preliminary plans for a building previously designed bythe industry professional dictating the lab. Students are then asked to complete a series of designtasks each week in the order they would occur in a professional environment. Each week thestudents are issued a set of drawings and necessary information to complete the task. They areasked to analyze, design and document their results and show their designs on the drawingsproviding all information pertinent to a practical and

The preferences of college-bound high school students are especially interesting in this regard. Eighty-six percent said they planned to participate in international courses or programs, and almost 50 percent expressed an interest in study abroad. That is a substantially higher rate than the 3 percent who currently go abroad and, if these preferences materialize, even somewhat, presages a substantial increase in demand. 2. The availability of other forms of campus-based international preparation was also im- portant. Nearly 8 out of 10 national survey respondents remarked that the

This courseplays the critical role of keeping students engaged in engineering while giving them experiencesthat have been shown to promote retention (see discussion below under “Utilization of BestPractices”).Each year of the curriculum has themes that we plan to emphasize. These are shown in Figure 2.In the first two years, we emphasize engineering basics and systems thinking. Two courses inthe sophomore year have been added to promote these themes and two existing laboratories wereadjusted. The two sophomore-level courses are Materials Selection for the Life Cycle, andNanotechnology, Biology, Ethics and Society. Both courses emphasize systems thinking, thefirst in the design process, the second through articulating

Throughresearch, discussing with several faculty members in the Engineering Technology Departmentand the Aerospace Department, came up with a plan to test our model. First we needed a model.The team drew a model in Inventor 8 and built a model out of Styrofoam using a FadalVMC3016. With the testing completed, the main factors that had to be improved were theweight and the angle of the hull. The team knew that the lighter the hull, the better the results,but after the DOE we knew by how much. The angle of the hull was critical. If the team had nottested the design, the angle of attack initially chosen would have been devastating. Now that allof the unknowns were solved, the craft was

That path usually began in theteenage years with an interest in amateur radio and tinkering with electronics, followed by mathand science courses in high school, then pursuit of a degree in engineering or technology.Unfortunately, that path has nearly disappeared over the last twenty-five years or so because ofthe evolution of electronic technology in ways that make it seem less accessible to tinkerers andamateur radio operators and because electronic
