This paper discusses the main links and some problems in the implementation of physics inquiry teaching in junior high school. The new round of basic education curriculum reform in China strongly advocates various disciplines. Cultivating students' scientific literacy is a fundamental goal of physics curriculum reform, and the key to effectively implement this goal is to actively carry out scientific inquiry activities. This requires a group of teachers with a sense of reform and innovation to carry out diversified inquiry teaching for all students. So what is inquiry teaching? This paper discusses the main links and some problems in the implementation of physics inquiry teaching in junior high school. Third, make full use of modern teaching methods. In the guiding process of inquiry teaching, teachers can use multimedia teaching methods to make students observe experimental phenomena more clearly, enhance perceptual knowledge and help students think rationally, so as to sum up the essence and laws through phenomena. When guiding students to carry out inquiry activities, we should pay attention to the combination with information technology (Internet). Modern technologies such as the Internet can be used in three aspects: on the one hand, students can consider looking for information and materials from the Internet to serve their own inquiry. On the other hand, students can use some computer software to process data. Thirdly, "Internet-based inquiry learning" has appeared on many websites in China. Students can register online, choose to explore topics and apply for tutors. In the process of exploring, students can record their progress at any time through the network, and the instructors (such as full-time staff and volunteers) arranged on the website can ask and guide students' exploration plans and actions at any time. For example, Excellent Research Institute and Dayan Science and Technology Education Network are all good attempts to combine inquiry learning with Internet technology and truly embody interactive learning. Such an attempt is conducive to realizing the ideal of "every student participates in inquiry learning" and realizing the transformation from traditional learning methods to modern learning methods. 4. Reflection on the educational idea of inquiry teaching From the perspective of Marxist philosophy, individual educational practice is dominated and influenced by educational ideas, and the influence of educational ideas on educational behavior is often latent and unconscious, so teaching reform is first of all the reform of ideas. When we learn a new teaching method, we should first study its principle and guiding ideology. Any new teaching method or classroom teaching mode is carried out under the guidance of certain educational and teaching concepts. Only by learning and mastering scientific educational theories, establishing a correct educational concept, renewing ideas and improving the understanding of "inquiry teaching" can teachers exert greater enthusiasm and creativity in their work and achieve remarkable educational results. 1, from focusing on teaching results to focusing on teaching process "focusing on results rather than process", the disadvantages of traditional classroom teaching are obvious to all. "Inquiry teaching" pays attention to the learning process, in which students' thinking methods and innovative ability are improved. The "achievement" of "inquiry teaching" is not necessarily tangible. According to the traditional teaching evaluation mechanism, its "achievement" is not very good, because it focuses on cultivating students' ability and innovative consciousness. In the process of "inquiry teaching", it is not important for learners to master a specific knowledge or skill, but the key is whether they can apply what they have learned, so as to discover and create something. In other words, the process of inquiry learning itself is the result it pursues. In the implementation of "inquiry teaching" in physics teaching, teachers should focus on revealing the process of knowledge formation, face up to the process of exploring nature in teaching and acquire knowledge through process inquiry. Let students discover the truth and master the law through the thinking process of perception-generalization-application. Students' thinking is trained in the teaching process, which not only increases their knowledge, but also develops their ability. 2. In traditional teaching, students should develop on average according to unified norms, instead of paying attention to unified and standardized knowledge transfer. Prepare lessons with a model, take classes with a method, take exams with a ruler and evaluate with a standard. This "factory" mode of student production does not conform to the reality of students, which inhibits the cultivation of students' personality and creativity, resulting in many problems and contradictions in current classroom teaching. Inquiry curriculum reform requires our teachers to pay attention to and study the differences between students. Only good students can explore. We should give every student the opportunity to participate in the inquiry, pay attention to guiding students to make everyone contribute to the inquiry activities, and let every student share and bear the rights and obligations of inquiry. Special care and positive encouragement should be given to some students with special learning difficulties and students with special talents. At the same time, inquiry teaching focuses on cultivating students' innovative practical ability, ability to collect and process information, ability to acquire new knowledge, ability to analyze and solve problems, ability to communicate and cooperate, and cultivate students' sense of responsibility for nature and society. In addition, every student is required to have a healthy body and mind, excellent quality, lifelong learning desire and ability, scientific and humanistic literacy. Develop a healthy aesthetic taste and lifestyle. So as to realize the development of all students and the all-round development of individual students. 3. From focusing on mastering knowledge to focusing on the application of knowledge and skills "inquiry teaching" focuses on the application of knowledge and skills, not how much knowledge is mastered. From the perspective of cognitive psychology, learning can be divided into three levels: the first level is the learning of concepts, through which we can understand the essence of things; The second level is to learn rules and understand the relationship between concepts; The third level is problem-solving learning, that is, using concepts and rules to solve problems. "Inquiry teaching" is mainly used in the third level of learning, and its purpose is to cultivate the ability to use scientific knowledge to solve practical problems, which is the fundamental difference between it and general knowledge and skill learning. At this point, "inquiry teaching" is different from discovery learning and heuristic teaching. "Inquiry teaching" has the characteristics of discovery and inquiry in form, but in content, its focus is on solving problems. Starting from the basic characteristics of application, "inquiry teaching" also has comprehensive characteristics. Comprehensive use of all kinds of knowledge can be solved; It involves a wide range of knowledge, and its content may be interdisciplinary. Compared with the general teaching activities of mastering knowledge, applying knowledge and answering questions (exercises), "inquiry teaching" makes students' learning closer to people's real life and social practice, and is more conducive to cultivating students' practical ability. Applying what you have learned is the basic feature of physics, and paying attention to the application of knowledge and skills provides a broad space for physics exploration. Why can the TV screen display all kinds of colors? Why can boiling water and popsicles release "white gas"? Why can you tell who is talking by listening to the voice? ..... Teachers should encourage students to use their spare time to go to factories, construction sites, docks and other places to observe and see where they have used their physical knowledge. If you learn "buoyancy", you can go to the dock to see the "waterline" marked on the ship and find out what the displacement is. After learning Simple Machinery, go to the construction site to see the big crane, see which part is the lever, which part is the axle and which part is the pulley block, and then further observe how these parts are used in coordination. There are too many such examples. Teachers should remind students to pay attention everywhere and link what they have learned with practical application, so that they can really learn physics well. 4. Focus on exploring middle school students' unique feelings, experiences and understanding of today's society. The fierce competition requires students not only to have rich knowledge, but also to have innovative ability. Therefore, modern school education should not only have the function of cultural communication, but also have the function of developing people's personality, improving people's quality and cultivating people's innovative spirit and creativity. A person's creative thinking is inseparable from a certain knowledge base, which should be an organic combination of indirect experience and direct experience. Indirect experience is a summary and refinement of previous direct experience. Direct experience is the feeling and experience gained by learners through personal practice. Only through direct experience can indirect experience be better mastered and used by learners and transformed into a part of personal experience system. In the inquiry activities, students will have different understanding and views on the problem, and will have different feelings and experiences. These learning experiences can bridge the gap between knowledge and ability. Because "creation" is not only a kind of behavior, ability and method, but also a kind of consciousness, attitude, concept and spirit. With the consciousness of creation, there is the practice of creation. "Inquiry teaching" should emphasize the important position of learning experience. The setbacks, mistakes, detours and even failures in the process of inquiry are of great educational value to students. In the process of personal inquiry, students experience setbacks and failures, success and excitement, and many of these feelings and experiences are the basis for them to understand the essence of science and the significance and value of scientific spirit. Even though some students took a detour, encountered setbacks and hardships, and even finally failed to find the answer to the question, they had to turn to the teacher for direct explanation, but the students still learned a lot from this experience. In their own words: "It turns out that scientific research is so difficult, and scientists are really powerful." "I've heard before that the road to science is not smooth. Only those who are fearless, brave and persistent on the rugged road can conquer the highest mountain. However, I need an indomitable scientific spirit for exploration. Today, through this setback and failure, I really have some initial feelings and experiences. " "The experimental results are quite different from our expectations. No wonder the teacher told us that we can't take it for granted. " 5. While emphasizing inquiry teaching, we should pay attention to the comprehensive application of various teaching methods. In fact, flexible and diverse teaching methods help to improve learning efficiency. Each teaching method has its own advantages and disadvantages. If used well, it will play a special role that cannot be replaced by other teaching methods. If it is not used well, this problem will also occur. If the teacher teaches well and speaks well, he can also convey a lot of useful information to the students visually; If you don't use it well, teaching will be boring and make people sleepy. Inquiry-based teaching can inspire and train students' thinking, but if it is not used well, it may also make the classroom discussion disorganized and digress from Wan Li. On the other hand, inquiry teaching takes a lot of time. If all the contents are taught by inquiry method, not only the teaching time is not allowed, but also it may not conform to the principle of economic education. Generally speaking, in the actual teaching process, we should comprehensively use a variety of teaching methods, learn from each other's strengths and promote each other, and we should not neglect one thing. In the era of rapid updating and development of knowledge, teachers in our education front are required not only to impart knowledge to students, but more importantly, to teach them learning methods and cultivate their ability to explore knowledge independently. Only with this ability can we adapt to the requirements of the development of knowledge economy in the 2 1 century. Yang Zhenning, a famous Chinese American, said in a report of Nantah that young people in China have a good theoretical foundation, but they need to strengthen their sense of innovation. Carrying out diversified inquiry teaching will undoubtedly bring great vitality to our education.
