Section T4A1 Meeting Two Needs: Teaching Engineering through Writing Chad A. B. Wilson Cullen College of Engineering University of Houston AbstractThis essay describes the theory behind the use of writing in engineering classes, as wellas several strategies for implementing such content-based writing. Despite thewidespread use of writing in disparate disciplines across the university, writing is notgenerally an integral component of “content” courses in engineering. In this essay, I buildon recent theories of

projects thatwere relevant to the class material at hand. Some of the criteria that the author used in selecting aproblem were: a) the design has to emphasize, or at least force the use of, concepts learned in theclassroom (e.g. symmetry and symmetry BCs), b) the execution of a project should not be verytime consuming.2) The second thing learned was that the implementation of PBL takes a significant portion ofthe instructor’s time.3) The instructor needs to alert students to verify assumptions made in their work, or when theysolve problems, before invoking such assumptions.4) The student groups should be required to meet with the instructor at least once and sufficientlyenough before the project deadline.

is clear. We have a great demand for itfrom both the student body and from industry. It is a field that is difficult to teach wellwithout a great deal of hands-on, applied experience, and we have tried to address that inthe development of our course offerings. And while the distance learning programcreates some extra challenges, there are situation where we have learned to takeadvantage of these and use them to the student’s advantage.

Thez-notch hinders the blade from twisting in either direction. The shrouds also providevibrational damping to help eliminate high cycle fatigue failure and prevent dangerousexcitation when the turbine goes through a harmonic mode upon firing up or shuttingdown.
