Student Backgrounds

One quarter of the students was already familiar with Pro\Engineer and most of the students had previous CAD experience. Some students needed several weeks to develop their Pro\Engineer skills so the project was not given until mid semester. Eighty three percent of the students in the class had taken Physics or Statics, so they were able to draw a simple free body diagram. All of the students were working as engineers, engineering technicians, drafting technicians, designers, machinists, or technical personnel at local area manufacturing companies. Also, all of the students were familiar with basic equipment and several students were familiar with experimentation and testing from their jobs.

Course Prerequisites

The prerequisites for this course are a computer graphics technology course (CGT 110) and another mechanical engineering technology course (MET 162). The CGT 110 course is an introduction to the graphic language using CAD and sketching to communicate design ideas. In CGT 110 students learn sketching, multi-view drawings, auxiliary views, pictorial views, working drawings, dimensioning practices, and section views. The MET 162 course is an introduction to analytical and computational problem-solving techniques. Students in MET 162 learn different ways to solve technical problems in mechanical engineering technology by using calculators, the factor-label method of unit conversions, and engineering graphs.

Class Project Assessments

The student’s designs were collected and reviewed. The rubrics were taken from some original assessments developed for this class and also some assessments that were used in previous classes 3. Table 1 shows the rubrics that the instructor used to evaluate the students. The completed projects and the project teams were evaluated in the following categories:

1.) Originality of Design 2.) Teamwork 3.) Oral Communication Skills 4.) Written Communication Skills 5.) Proper Use of Design and Drafting Principles 6.) Technical Accuracy 7.) Practicality/Applicability 8.) Pro\Engineer Skills
