Remote Laboratory for Activating Lecture Hall Teaching and Distance Learning

Abstract

This paper presents two remote laboratories (RL), which are used for activating a large cohort in a classical lecture hall as well as in distance learning. These RLs are part of a didactic concept based on the approach of problem-based learning. In problem-oriented exercises, the students plan, implement and check their solutions in remote experiments. The first RL offers eight experiments for the students based on PLC and microcontroller programming, whereas the second RL provides seven demonstrations on task scheduling. The second RL’s unique feature is a horizontal didactic reduction from a calculation process to a task of a crane robot. The RLs are accessed via a self-developed RL management system. The evaluation of the field test shows that students’ motivation has increased and the link between theory and practice has been improved. Furthermore, the students’ exam results have improved. However, students criticize the additional time required for the remote experiments.
