The development of new experimental teaching materials for learning of "energy and chemical reaction" to visualize invisible phenomena

许多年轻一代的初中科学教师在高中时受过的物理教育很少。即使他们在高中接受了物理和化学教育，他们也学习了化学，而不是与物理相关。因此，他们可能在没有完全从原子水平上从化学键解离和形成的角度来理解化学反应和伴随的能量转换之间的关系。在本研究中，我们开发了科学教师培训的实验教材，从微观现象(即键的解离和形成)的角度来解释化学反应是可感知的宏观现象(即吸热和放热)。

Many of junior high school science teachers of younger generation are poorly educated about physics in high school. Even if they received education for physics and chemistry in high school, they have learned chemistry without correlating with physics. Accordingly, they probably teach the relation between chemical reaction and concomitant energy conversion without understood fully from the viewpoint of chemical bond dissociation and formation at atomic level. In this study, we developed the experimental teaching materials for science teacher training to interpret chemical reaction being the perceptible macroscopic phenomena (i.e. endotherm and exotherm) from the viewpoint of microscopic phenomena (i.e. bond dissociation and formation).
