Institute,known for its Manufacturing and Mechanical Engineering Technology (MET) programs. The course had twotracks: (1) interpreting engineering drawings (IED) which is traditional drafting, and (2) CAD training (AutoCAD,release 12). Textbooks for the course were Interpreting Engineering Drawings by Jenson and Hines (for the IEDtrack) and Using AutoCAD Release 12 by J. E. Fuller (for the CAD track) [1,2]. Students were also required tocomplete a computer aided drafting project (such as the “trolley” assembly from the IED book). Currently, the course retains the same basic format, although as technology has advanced, the CAD softwarehas necessarily changed over the years from what was largely computerized drafting (using AutoCAD, release 12

The first step was to separate the roteaspects of the laboratory experience from the more creative aspects of instruction thatare often truncated because laboratory

Realworld experiences were gained from this activity, and the most effective way for students tolearn design by doing open-ended design projects that require a device to be built wasaccomplished.PRIMARY OBJECTIVE OF CONTESTThe primary objective of the contest was to build a fully automatic device that would tossbaseballs into a rectangular box consisting of three separate compartments. The device had to fitinside a storage box 30 by 50 by 30 cm before assembly and 1 m by 1 m by 1m space uponassembly and was located 235 cm from the box. The three separate compartments of the box had20 cm diameter holes cut in their top enclosures.The device was to toss 30 baseballs within a two

Please note that the identified characteristics arehighly related and in many cases, by redirecting students’ efforts, an unfavorablecharacteristic can become a great asset. 1. They are not challengeable. In general, the students are not willing to accept challenges. When things are hard and the first sign of an unacceptable grade or class performance is seen, the first reaction of many students is to panic and quit. This usually manifests itself in a change of the field of study as well as dropping the class, changing schools, or just not working on classes any more and accepting the

Because students can register for 1-3 credits, much of the work distribution happens in these groups, and students are responsible for taking on the correct amount of work as deemed by their credit hours. (We try to help with time allocation, but there are always 1-credit students who do three credits’ worth of work…and vice versa.)

Innovations have occurred in the area of biology, chemistry,electronics, metallurgy, physics, and sociology. Specific applications in the fields ofaviation, energy, graphics, materials, medicine, nanotechnology, software andtransportation have been driven by computer and electronic-related changes (Benditt,2002).The rapid introduction of new computer and electronic-related technologies has posednew problems that need to be addressed.

There is no dedicatedlaboratory section associated with this class. In essence the use of a microcontroller allows topics, hitherto taught purely in the classroom(sometimes with the aid of demonstrations), to become the object of direct practical experience for thestudents. The topics include A/D conversion, sensor calibration, self regulation, on-off control,proportional (P) control and offset, proportional and integral (PI) control, the position and velocity formsof the PID algorithm, selection of the control interval and signal aliasing, step tests and tuning.

Because technology is value laden, we needto consider what kind of values our technological choices will uphold, which leads us to the questionof normativity in technology.Normativity prescribes how something ought to be. Assuming a holistic outlook on technologicalartifacts, we assert that they function in all aspects of reality. The question then is how is an artifactto function?
