Abstract

Using Natural Sketch Recognition Software to Provide Instant Feedback on Statics Homework: Assessment of a Classroom PilotDespite the importance of hand-sketched Free Body Diagrams for engineering education andpractice, large class sizes often prevent detailed feedback on such diagrams. Relatively recentlycomputing technology has become powerful enough to enable rapid and plentiful feedback onhand-sketched engineering diagrams. Researchers have recently developed the free “Mechanix”sketch recognition tutoring system for free body diagrams (FBDs) and trusses which providesintelligent and immediate feedback.This paper will describe the process and results of piloting this software at a primarilyundergraduate university with approximately 40 students enrolled in a Statics class, contrastedwith a control group. Results will include attitudes towards technology, online homeworkscores, test scores, and self-reported perceptions of the effectiveness of the sketch-recognitionsoftware. Preliminary results look very positive, and the full paper will include a detailed dataanalysis of both quantitative learning outcomes and qualitative comments from users.
