Dr. Branoff is a professor and chair of the Department of Technology at Illinois State University. He taught engineering graphics, computer-aided design, descriptive geometry, and instructional design courses in the College of Education at North Carolina State University from 1986-2014. He also worked for Siemens-Switchgear Division and for Measurement Group, Inc. Dr. Branoff's research interests include constraint-based solid modeling strategies and spatial visualization abilities in undergraduate students. He has conducted CAD and Geometric Dimensioning and Tolerancing workshops for both industry and education professionals. Dr. Branoff served as President of the International Society for Geometry and Graphics from 2009-2012. In 2013 he was elected into the Academy of Fellows of the ASEE, and in 2014 he received the Distinguished Service Award from the Engineering Design Graphics Division of ASEE. In April of 2015 Dr. Branoff received the Orthogonal Medal for distinguished service in graphic science from the Technology, Engineering & Design Education faculty at North Carolina State University.
Abstract
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.
