Based on Life Examples, Guide Students to Think and Understand Physics Knowledge Step by Step---- Case Study of “Refraction of Light” Teaching Design

Taking life examples as scenarios, this paper studies the topic of guiding students to think and learn physics knowledge step by step, and makes a case analysis through the teaching design of “refraction of light”. Physics is an important part of human science and culture. It is a natural science that studies the law of matter, interaction and motion. Our daily life contains a variety of physical knowledge and physical laws. Students can explain many phenomena in life by learning physical knowledge. Therefore, it is a matter of concern for junior middle school physics teachers to make students interested in physics at the beginning and in the process of learning, which requires teachers not to teach with old teaching methods, Instead, we should adopt some teaching methods that are easy for students to understand and close to students' life. Taking the teaching design of “refraction of light” as an example, this paper briefly discusses the application of “guiding students by life situation” in junior middle school physics teaching.
