On the other hand,HOLYCOW features animation. The animation includes a real-time movie of the varying tan-gential stress on the hole boundary as the direction of the applied load changes.2.5 HFAILThat composite strength is directionally dependent can complicate design. Also, even laminatestrength is usually assessed on a ply-by-ply basis. Numerous different strength criteria have beendeveloped and a variety of them are used in industry.

. Recently,many engineering educators have seen this “criterion swell” as symptomatic of rules that havebecome too cumbersome, too prescriptive, and a recipe for the evolution of “cookie cutter”programs. In fact, some have charged that the current ABET general criteria constitute anegative incentive for sound educational experimentation and the evolution of better teachingmethods. Although Criterion II.A.7 encourages well-planned experimentation, the engineeringcommunity has been reluctant to pursue such experimentation. Undoubtedly, the hesitation topursue such experimentation may, in part, be traced to a fear of restrictive interpretations of the“old criteria.”In the early 90’s, many outstanding institutions became openly frustrated with the

His initial effort was ahead of its time, because the software to support actual Page 2.188.1processing was neither widely available nor easy to use in the 1970's. More recently, Steiglitz haswritten another book that presents DSP material to students with a computer science background,but with a keen interest in digital audio and computer music [2].

In order to design such products, an engineer must have generalknowledge of various design techniques and special knowledge of a blend of technologies. Suchskills can be obtained from multidisciplinary mechatronics courses. Recognizing the need for mechatronics education, some Japanese higher educationalinstitutions[1] and European colleges and universities[2-4] offer courses in mechatronics atdifferent levels. Some schools abroad even plan to offer degree programs[5] in mechatronics.The significance of this can be underscored by the fact that there is already an

companies are realizing the advantages of the team approach. An example ofthis is the recently introduced Saturn automobile. In the early 1980's General Motors decided todesign a new automobile from the ground up. To accomplish this, they formed a team of productspecialists from various General Motors divisions. Rather than assigning this team to one of theexisting GM divisions they chose to form a new company, Saturn. Many companies do not go tothe extreme of forming a new company, but they are bringing together technical specialists toeffect new product designs.[3]Teamwork is also key to the successful operation of manufacturing cells on the shop floor.

The purpose of this experiment was to find out if we could provide students with usefulfeedback on their writing (especially their weekly critiques of the assigned seminar readings)without the need for extensive editing of each written assignment. The reading critiques weregenerally 2-3 pages long; in each paper, students were asked to briefly summarize the readingsassigned for each seminar and then critically analyze one or two of the major argumentsdeveloped by the author(s).The first step in this process was developing the scoring rubric shown in Table I [adapted fromref. 6].
