Abstract

Due to the technological advancements and proliferation of the mobile-phone industry, smartphones are increasingly being utilized as an educational tool to improve student learning. The paper herein considers the use of smartphones as a ready-made tool for engineering dynamics students to design and conduct real-world experiments to increase both their excitement and knowledge of course material. In the past, large class sizes and the cost of measurement instrumentation made student-led experiments cost prohibitive. However, with the vast majority of students now owning a smartphone, most students now have access to an instrument with remarkable capabilities to measure and record engineering data. In particular, the on-board three-axis accelerometer allows students to measure experimental acceleration for comparison to theoretical calculations. Based on relevant course content and with instructor approval, students designed and conducted an experiment to investigate and measure the dynamics within the proposed study. The topics were open to the students’ imagination and concerns as long as they considered acceleration measurement and comparison. Examples included swinging, driving, flying, tumbling, dancing, impacting, free-falling, etc. Groups of two to three students worked together and submitted a single report. According to ABET accreditation guidelines, this project could be utilized to assess the categories of (b) the ability to design and conduct experiments as well as to analyze and interpret data and (k) an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. Based on a detailed project report analysis, these categories were assessed and the results provided herein. Finally, a class survey was conducted to gauge the students’ level of excitement for the course material as well as their increased sense of understanding resulting from the project.
