Learning pronunciation well is the basis of learning English well, and doing a good job in pronunciation teaching is the key to the teaching of Introduction to English, which is a summary of English teachers' experience for many years. However, in teaching, I found that students' pronunciation learning effect is not ideal: poor spelling ability, unable to remember phonetic symbols, the phonetic symbols and literal images of words or sentences are inconsistent with numbers, and more importantly, students have a bad psychology of "fear" and "fear" about pronunciation. Therefore, how to innovate and make students pass English exams easily, happily and smoothly has become a common topic for English teachers in primary schools. First, the concept of innovation.

First of all, we must grasp the purpose and requirements. Some teachers think that adding phonetics, especially phonetic symbols, will increase students' learning burden. In fact, from the perspective of the development of phonetic learning, the use of phonetic symbols is beneficial for learners to better master pronunciation. Once students learn phonetic symbols, they can not only learn new words easily, but also review words or forget pronunciation without the help of teachers, which improves efficiency.

Secondly, we should break the teaching concept of "I teach you to learn". Although, "the teacher preaches, teaches and dispels doubts." But if teachers focus on boring "preaching" and boring "teaching", students will feel afraid of English. Even tired of learning. Constructivism theory holds that students are the builders of knowledge, and they "learn" knowledge instead of "teaching" it. Therefore, when teaching phonetics, teachers should try to let students think independently, let them get information, use knowledge to solve problems, change passive learning into active learning, and then have the ability to apply and innovate knowledge.

Thirdly, we should put stimulating and cultivating students' interest in learning English phonetics at the top of the reform and innovation of English phonetics teaching. Interest is the best teacher. With interest, learning motivation and emotional sparks can be generated, and the emotion of interest is the internal driving force for sustainable development. If students can feel the joy of English pronunciation learning and stick to it, it will have a great impact on the development of students' pronunciation ability and the improvement of overall English quality.

Second, model innovation.

In the past, English phonetics teaching mode was mainly based on knowledge imparting and skill training. Its disadvantages are: emphasizing teaching over self-study, emphasizing injection over exploration, emphasizing generality over individuality, and emphasizing short-term over long-term. It is not conducive to the embodiment of teaching democracy, the development of students' personality and the cultivation of students' interest in learning, innovative consciousness and innovative thinking. According to the characteristics of teaching materials, combined with their own teaching practice, this paper explores another primary school English teaching model: spelling comparison method as the main method, supplemented by phonetic comparison method. The purpose of phonetic teaching in primary schools is that primary school students should master most phonetic symbols, but not necessarily the relationship between sound and shape, especially some difficult phonetic symbols rules. Therefore, in the teaching process, teachers should pay more attention to the repeated spelling and pronunciation comparison of phonetic symbols, such as /keit/, /kait/. Over time, students will master the spelling methods of phonetic symbols independently. Although the relationship between pronunciation and spelling is not the focus of teaching, students do not need to try to figure out their pronunciation according to the phonetic rules when they meet a new word, but in constant practice and practice, students will naturally experience some simple corresponding relationships between pronunciation and spelling.

Therefore, in the process of primary school pronunciation teaching, students should not be required to remember too many corresponding phonetic symbols.

Third, innovation in methods.

Traditional phonetic teaching methods, such as teaching and training, are more necessary. However, with the renewal of ideas and the innovation of models, more innovative teaching methods are considered in teaching, such as discussion, discovery, questioning, emotional communication and self-practice. In particular, we should use some methods to stimulate students' interest in learning, arouse their enthusiasm and initiative in learning, and help them explore new knowledge themselves.

Learning pronunciation well is not only a good foundation for learning English well, but also a shortcut for children to master words through experience summary and innovation. The Doctor's Hall International Education and Training Institute has approved an American phonetic alphabet course for primary school students, which includes the pronunciation practice of international standard phonetic symbols such as vowels and consonants, and how to memorize words skillfully. Our teachers have created their own teaching methods with years of teaching experience, and strive to innovate constantly on the basis of teaching, so that children can enjoy learning English in their studies.
