新课标明确提出:数学知识的教学,要注重知识的“生长点”与“延伸点”。近几年,笔者在课题研究的实践中深刻感悟到:我们需要,也应该关注、把握学生的学习起点,在此基础上设计、组织教学,提高数学课堂教学效率。一、关注学习起点,精心设计预案教师在进行教学设计的过程中,不仅要考虑课标要求和教材的内容,还要对学生知识与经验的现实起点进行充分的把握,准确地定位教学目标,合理地设计教 The new curriculum clearly put forward: teaching of mathematical knowledge, we should focus on knowledge “growth point ” and “extension point ”. In recent years, the author deeply felt in the practice of subject research: we need and should pay attention to grasp the starting point of students’ learning, on the basis of which we design, organize and improve the teaching efficiency of mathematics classroom. First, pay attention to the starting point for study, well-designed plan Teachers in the process of teaching design, not only to consider the requirements of course standards and teaching materials, but also the students knowledge and experience of the starting point for a full grasp of reality, accurate positioning of teaching objectives, Rational design of teaching
