Hands-on Experiments vs. Computer-based Simulations in Energy Storage Laboratories

This cross-over study compares student laboratory work conducted in two different learning modes: first as a practical hands-on exercise and second using computer-based simulations. The research methodology was optimized to avoid other effects on the learning outcome. To evaluate the influence of the mode, short tests on knowledge gained during the previous experiment were conducted at the beginning of the next laboratory session. In 2016, forty students have taken part. Overall learning results of hands-on experiments were slightly better than those of simulated laboratories, but the difference in performance was not statistically significant. The study is continuing in 2017 with 30 participants. In addition to the knowledge tests, after each laboratory session the students were asked for their opinion in an online survey. A similar percentage of the students stated the execution of the experiments is beneficial for their future professional life. In the hands-on learning mode more students expressed they have acquired new knowledge. Although more students assessed the simulated laboratories as more challenging compared to hands-on experiments, more students mentioned obstacles while conducting the hands-on equivalents.
