Abstract
Mobile phones and tablet PCs can be used in learning environments and treated as teaching materials similar to notebooks and textbooks through the use of applications and software. With these electronic devices, we can do things that cannot be realized with notebooks and textbooks, one of which is programming. The objective of this study is to develop physics simulation materials using Python so that learners can both understand physical phenomena and deepen their programming knowledge through the simulator. This paper shows two mock lessons as examples and indicates that our aimed educational effects, which were measured with questionnaires, can be obtained.
