TEC333 Geometric Dimensioning and Tolerancing addresses two of the overall program outcomes in the [program name] program at [institution]. These outcomes include utilizing 2-D and 3-D computer-aided design systems to create drawings and models for products, machines, jigs, fixtures, and other mechanical devices used in manufacturing environments and being able to read and interpret manufacturing documentation such as blue prints, technical drawings and diagrams, production plans, tooling plans, quality plans, and safety plans. One of the key outcomes of TEC333 is that students can apply appropriate datum reference frames to designs. Students are asked to demonstrate their understanding of the datum reference frame concepts in several ways throughout the course on a pretest, tests, online quizzes, modeling & drawing assignments, CMM assignments, and the final exam. Specific examples include labeling a datum reference frame origin on a given drawing, sketching datum feature symbols on a drawing given sentence descriptions of the datums, identifying established datums when given a drawing, modeling parts with the datum reference frames consistent with the datum reference frame on a given drawing, and designing datum reference frames for parts within a given assembly. This paper will present ways students are assessed on datum reference frame topics, present the results of these assessments over the last several years, and provide recommendations for future work.
