The Characteristic Curve Remote Lab: Evaluating the Light Bulb Exercise on Temperature-Dependent Resistance

This article presents an approach to teaching temperature-dependent resistance and characteristic curves using the Characteristic Curve Laboratory, a remote laboratory developed within the OnLabEdu project. The designed learning arrangement aims to deepen the understanding of temperaturedependent resistances of students at university level. In this article, the learning arrangement and an explorative first evaluation using a survey containing several selected aspects (e.g., autonomy, interest, flow, failure, perceived choice, perceived competence, handling), conducted with 18 students at early tertiary level, is presented. The results show positive ratings for handling and time management, but indicate issues with scale reliability, particularly for autonomy and perceived choice. The variability in fear of failure and flow suggest areas for improvement in the learning arrangement.
