Keywords:Model Experiments, class

Model experiments are widely recognized as intuitive understanding tools and are often used in classes as demonstrations. Here, students would gain a much deeper understanding if they were involved in the experiments rather than just watching demonstrations. So, we tried to organize a class where students carried out experiments of their own choice and then compiled and presented them in video form. The target group was students enrolled in the Master's course at the Graduate School of Environmental Studies, Nagoya University. In the first half of the 15-lesson course, the students mainly studied, and in the second half, they carried out their experiments. In the first half of the course, we alternated between classroom lectures and demonstration experiments. In the classroom lectures, the students studied and introduced the physics necessary for their research, and the following week, the lecturer presented a demonstration experiment related to that physics. In the demonstration experiments, we made sure to introduce techniques that are often used in model experiments. In the second half of the class, each student carried out a simple model experiment and presented a video shorter than 5 minutes. The theme of the experiment was left up to the students. For the second half of the class, we prepared several reference books on model experiments so that students could carry out a certain level of experiment by following the book. The students produced many of the excellent videos, as seen in the following URL.
We polled their impressions of the class, and many gave positive feedback, saying things like 'It helped me to understand intuitively' and 'It was fun.' On the other hand, many students commented that the model experiments had the disadvantage of being unable to perform quantitative measurements. It is possible to perform quantitative measurements easily even with model experiments, but this may be because they take time and effort, so we omitted them from the class. Alternatively, students may think model experiments are not worth the time and effort. In addition, when asked about the difficulties of model experiments, many students mentioned 'experimental methods and experimental designs,' Along with quantitative measurements, perhaps the key to popularizing model experiments is to introduce simple, inexpensive, and commonly used methods in an easy-to-understand way.
This poster will detail and introduce the students' videos, comments, and poll results.
