宜昌市第七中学于2002年秋季开始使用人教版《义务教育课程标准实验教科书·化学》九年级上册(以下简称新教材)。笔者使用该教材数月以来,深感教材内容弹性很大,给了任课教师一个充分施展自己才能的广阔空间。因此,从自己对新课程标准、新课程观的理解出发,试着对教材里的几个实验,进行了重新设计。
The seventh middle school of Yichang City began to use the “First Compulsory Education Curriculum Standard Experiment Textbook Chemistry” Grade 9 (hereinafter referred to as the new textbook) in the fall of 2002. The author has used this teaching material for several months and has felt that the content of the teaching material is very flexible and gives the teacher a broad space to fully display his or her abilities. Therefore, starting from the understanding of the new curriculum standards and new curriculum concepts, we tried to redesign several experiments in the textbooks.
