Using Peer Review in a Freshman Engineering Graphics Course to Enhance Understanding of Basic Dimensioning TechniquesAppropriate application of basic dimensioning techniques is a topic that students enrolled in anintroductory engineering graphics course have problems with on an ongoing basis. Errors thatoccur regularly on assignments and exams, despite instruction, assignments, and required readingon the topic, include poor placement, missing dimensions, over dimensioning, and incorrectformatting.In an attempt to improve students’ dimensioning techniques and reinforce the importance ofbeing able to read drawings that others have created, peer review of select assignments will beintroduced into the course during the fall 2014 semester. Currently, drawings are graded solelyby the instructor and returned to the students with feedback. General comments are made to theclass at large on what students are typically getting correct and incorrect on the assignments, andoccasionally individual students will ask for more detailed feedback on their work but this is theexception more than the rule.As part of the new peer assessment plan, students will turn a print of the multiview drawing in tothe instructor at the beginning of lab then the assignments will be shuffled and randomly handedback to students so they will not be grading their own work. A copy of the correctly dimensioneddrawing will be projected on the screen in front of the class and on the students’ computermonitors. They will be allowed a limited amount of time and required to analyze the drawingthey have been given, mark any errors they find, and ask questions. Students will letter theirname on the drawing to indicate they are the person who marked it up. Part of each student’sgrade on the assignment will be determined by how well they marked up the drawing they weregiven.Grades on the individual assignments will be compared to those from previous semesters to seeif there is an improvement in the student work on the dimensioning assignments after the peerreview has been implemented. Grades on exams and quizzes that have content related todimensioning will also be compared to see if there was an overall improvement in students’dimensioning techniques.
