ArViz: An IoT Teaching Tool for High School Students

This work aims to evaluate ArViz as an IoT teaching tool for new inexperienced students. ArViz (Arduino Vis(z)ual Programming) is wrapped in a graphical interface to help inexperienced or novice programmers acquiring IoT programming skills with Arduino compatible boards. In this work, ArViz is used in high school IoT programming classes. Student performances in the class are then analyzed using multiple choice tests and questionnaires. The evaluation results based on a paired sample t-test indicate that the students skills are improved with 95% confidence interval. The overall platform satisfaction is over 80%. With ArViz, the learners enjoy their classes as if they were playing a puzzle game.
