DEVELOPING GOOD MATHEMATICS TEACHING PRACTICE THROUGH LESSON STUDY: A U. S. PERSPECTIVE

Although there is no consensus on what constitutes good mathematics teaching practice in the United States, a recent document published by the National Research Council (NRC) offers a vision that might be acceptable to the various stake holders. The NRC document considers teaching as an “interaction among teachers and students around content.” Lesson study may play a significant role in developing and spreading good mathematics teaching practices that are in alignment with the vision presented in the NRC document. In this paper (and accompanying video of a lesson), we will discuss some specific features of good teaching practices and how lesson study may contribute to the development of such practices. We will conclude the paper with a brief discussion of future research that may be fruitful.
