During the Fall 2016 semester a geometric dimensioning and tolerancing course was offered for the first time at [University Name]. The course was offered again during the Fall 2017 semester. The course learning outcomes included symbol identification, identifying features with and without size, specifying GD&T within given design scenarios, calculating virtual condition, determining advantages for different material condition modifiers, applying datum reference frames to designs, and demonstrating proper inspection set-ups and procedures for verifying geometric tolerances. A pretest was given at the beginning of each semester to assess students’ prior knowledge. Other assessments later in the course (e.g., online quizzes, tests, and final exam) included parallel assessment items to those included on the pretest. This paper will outline the main topics and structure of the course, summarize some of the assessment data gathered during the Fall 2016 and 2017 semesters, and analyze student performance on concepts presented during both semesters.
