Physics based on experiments, experimental observation and analysis capabilities for students, student interest in studying physics and the spirit of scientific inquiry irreplaceable significance. For a long time, because the shortage of educational resources, examination-oriented education, lack of awareness on the importance of experimental teaching and other reasons, making the experimental teaching has not been well carried out, leading our students to explore and innovation consciousness. Today, the gradual improvement in secondary education facilities, audio-visual equipment is also widely used in teaching. However, adding the experimental equipment and advanced audio-visual facilities are still far from meeting the needs of experimental teaching for teaching aids. Zizhijiaoju in alleviating the shortage of teaching facilities, students observe and analyze capabilities, practical ability, scientific inquiry and innovative spirit, and so has a unique advantage. However, according to the author survey, many teachers did not personally done aids, hands-on production also exist in many difficulties, therefore, be the subject of study is a more practical value. This paper is divided into five chapters: The first chapter is introductory part, the author analyzes the gap between domestic and carry out experimental teaching, Zizhijiaoju ability in students a unique advantage. Finally, pointing to the significance of this project carried out; second chapter Zizhijiaoju understanding of the author from Zizhijiaoju definition, function, meaning, and to analyze the situation and deepen the understanding of all aspects of Zizhijiaoju; chapter describes how to design and production Zizhijiaoju; fourth chapter Zizhijiaoju case in which \Especially the \passion; fifth chapter the author analyzes the relationship Zizhijiaoju and teaching effect and designed Zizhijiaoju teaching cases, teaching practice has proved Zizhijiaoju in the experimental teaching important role. The author's main work is reflected in two aspects: First, a comprehensive exposition Zizhijiaoju definition, function, meaning, status and relationship with the teaching effect, eliminating the lack of awareness of teachers Zizhijiaoju. Second, the past three years, I actively hands-on development and production of some simple principle, demonstration effect is obvious, very useful in the new middle school teaching aids. This not only provides a reference for the majority of teachers instance, can also promote the enthusiasm of teachers hands-on production aids.
