当前,上海的中学数学课堂教学改革正在深入进行,数学课堂教学正在不断地变化,从只关注教师的教转向关注学生的学,从单一的讲授式到多种教学方式结合的教学,从只借助黑板呈现到现代教育技术与传统技术相结合的多元呈现等,二期课改的以学生发展为本的理念正通过数学教师的课堂实践逐步落实.但实际的数学课堂教学中还是存在一些问题,特别是有些教师对具体教学策略的研究不够,往往对一些疑难问题缺乏具体的应对策略,从而影响教学的有效性.
At present, Shanghai’s middle school mathematics classroom teaching reform is being carried out in depth, and mathematics classroom teaching is constantly changing. From focusing only on teachers’ teaching to paying attention to students’ learning, from single teaching styles to multiple teaching methods combined teaching, only with the help of The concept of blackboard-based modern education combined with traditional techniques and multi-element presentations, and the concept of student-based development in the second-phase curriculum reform are gradually being implemented through the classroom practice of mathematics teachers. However, there are still some problems in practical mathematics classroom teaching. In particular, some teachers do not have enough research on specific teaching strategies. They often lack specific strategies for solving difficult problems, which affects the effectiveness of teaching.
