新课改在我们农村中学已经实施十多年了,作为一名课改实验教师,在农村基层学校经过多年的教学实践,深切地感受到了利用几个理念,可以事半功倍搞好数学教学。一、让学生充分经历知识的发生和发展过程在数学课堂上,我们经常看到,有些教师上课时就题论题,将各种结论按照课本的呈现顺序灌输下去,学生被动地接受这些结果,死记硬背、机械模仿,成为复制知识的工具,不知道它们的发生过程,不知道它们的思维过程,因而,对于知识没有相 The new curriculum reform has been practiced in our rural middle schools for more than ten years. As a teacher of curriculum reform experiment, after years of teaching practice in rural grass-roots schools, I deeply felt that using several concepts can improve my mathematics teaching with less effort. First, to enable students to fully experience the occurrence and development of knowledge In the mathematics classroom, we often see that some teachers in the classroom questions, the various conclusions in accordance with the order of presentation of textbooks instillation, the students passively accept these results, Hard back, mechanical imitation, as a tool to copy knowledge, do not know the process of their occurrence, do not know their thinking process, therefore, no knowledge of the phase
