Digital homework for kinematics and dynamics of machinery

Abstract

A digital homework program applicable to the study of kinematics and dynamics of machinery has been developed and successfully incorporated into an ongoing kinematics and dynamics of machinery course providing students with regulated self-practice, formative feedback, and partial credit scoring. The use of digital homework in upper-level engineering courses is sparsely documented in the literature but can provide homework assignments that give immediate feedback for self-assessment of learning while significantly reducing the time required of the instructor for grading. This paper presents a procedure for creating a digital homework set generally applicable to engineering courses using a commercially available course management tool. The paper then documents a specific implementation into a junior-level kinematics and dynamics of machinery course. This implementation is assessed over four semesters based on its comparison with traditional homework as perceived by students. The responses indicate that students were acquainted with digital homework from pre-engineering courses and did not regard the digital format as a hindrance. However, students perceived no benefit to the immediate feedback and, therefore, preferred the traditional format of upper-level courses. This perception is attributed to students’ tendency to make use of the homework feedback much later after the assignment and primarily at the point of exam preparation. However, this seems to be counter to the role of homework as a formative feedback tool that students use in real time to gauge and regulate learning activities. The authors conclude that the presented digital homework is both efficient and appropriate as a teaching supplement to an upper-level kinematics and dynamics of machinery course in the light of the role of homework as a tool to regulate learning of course material. Examples of the implemented digital homework problems are provided to serve as a resource for other instructors.
