To be specific, Wan Xu prepared meticulously beforehand. Therefore, this lesson was full of highlights. For instance, in order to allow students to better grasp the direction and change of the law of light in addition to light reflection and refraction in the application of life, Wan Xu let students clearly see the experimental phenomenon by means of wireless screen projection technology. Also, students actively explored through group work. Furthermore, Wan Xu developed a lot of light reflection and refraction phenomena that are common in life and textbooks, such as clear water, shallow water, mirage and so on.

To conclude, not only did this lesson give students a new understanding of light, but also made teachers aware of the significance of flexible teaching methods and innovative educational methods to stimulate students’ interest in learning, which played a good role in demonstrating and leading.
