Distance Learning with Hands-on Exercises : Physical Device vs. Simulator

Abstract

This Research to Practice Full Paper presents a comparison between a physical device and a simulator in a distance learning context. Programming embedded devices is very commonly taught using embedded hardware. One of the most used solutions is the Arduino microcontroller platform, which allows small embedded applications to be built and commanded in a programming language. However, there are some challenges in using physical devices for educational purposes. These challenges are particularly acute in distance learning or when the course needs to be scalable to a varying number of students. To address these challenges, we explored the potential of a simulator as a replacement for a physical device. We implemented the course using both the physical device and the simulator and collected student and lecturer feedback and experiences. The results showed that the physical device is somewhat more concrete and motivating, but the simulator is also very well suited for the purpose. The technical solution did not seem to have an impact on course completion or workload. There are also some advantages of using a simulator over a physical device, such as the possibility to test electronic connections without fear of breaking down the equipment.
