Chemistry Bulletin Volume XV of the first issue of Beijing Secondary Chemistry Teachers Teaching and Research Institute wrote ’on the northeast version of junior high school chemistry textbook discussion (a)’ article on the textbooks junior high school textbooks, two chapters, the first high school Chapter some of the inappropriate place to make the necessary changes, and teaching methods and the use of classroom time put forward specific views on the quality of secondary chemistry teachers in improving the quality of teaching is great help, but in reading After the article has the following comments made for readers reference, and hope to be criticized.
