Study Of High School Mathematics Teachers' Professional Knowledge Development

The final purpose of education is for students' development. Teacher and his level of knowledge affect not only the implementation of teaching but also the learning of students. What knowledge a teacher owns will have a great influence on students' future development. Along with further development of curriculum reform in senior high school, they will face new problems and new challenges in teachers' professional knowledge and teacher education. Whether the new curriculum reform can be successfully put in practice, the development of teachers' professional knowledge will play a very important roll.This paper will mainly study the development of professional knowledge of teachers in senior high school, who teach mathematics. In a word, there are three parts in this paper: the theoretic analysis of teachers' professional knowledge in mathematics, the investigation of the current level of teachers' professional knowledge, and the approach to develop teachers' professional knowledge.Concretely, in the first part, we expatiate with the concept of knowledge, which is the epistemology base. Then we explain the concept of teachers' professional knowledge in mathematics from two sides: the meaning and the extension. This is one innovation of my paper. And we advance an all-around model of the types of teachers' professional knowledge, by cleaning up other ideas. This is another innovation. At last, the paper analyses the mechanism of developing knowledge.In the second part, we make an investigation on the current level of teachers' professional knowledge. And we have found that teachers are not up to the demands of new course.So, in part three, the paper introduces some approaches of developing teachers' professional knowledge in mathematics, putting out the matters to pay attention to. We hope the paper will have some benefits for teachers.
