《义务教育全日制小学数学教学大纲》(初审稿)明确指出:“学生初步的逻辑思维能力的发展,需要有一个长期的培养和训练过程,要有意识地结合教学内容进行。”对此,我有以下三点认识。一、在进行课堂教学时,要重过程,分层次课堂教学是当前教学的主要形式,所以结合教学内容发展初步逻辑思维,主要应在课堂上进行。为了安排好一节课40分钟的教学内容,教师要把确定的内容分成几个层次,每个层次又要设计一些教学步骤,积极引导学生一步一步地走、一层一层地攀,让学生在“获取知识”和“运用知识”的过程中,得到一个符合逻辑的结论。这样,也只有这样,学生初步逻辑思维能力才能得到发展。现以“乘法分配律”的教学为例加以说明。
“Compulsory education full-time elementary school mathematics syllabus” (preliminary review) clearly states: “The development of students' initial logical thinking ability needs a long-term training and training process, which should be consciously combined with the teaching content.” In this regard, I have the following three points of understanding. First, in classroom teaching, we must re-process, hierarchical teaching is the main form of current teaching, so the combination of teaching content to develop the initial logical thinking, mainly in the classroom. In order to arrange a lesson for 40 minutes of teaching content, teachers should be certain content is divided into several levels, each level and also to design some teaching steps, and actively guide students step by step, step by step to climb, so that students In the process of “getting knowledge” and “using knowledge”, we get a logical conclusion. In this way, the only way to improve students' initial logical thinking ability can be developed. Now the teaching of “multiplication law” as an example to illustrate.
