《数学广角》在人教版小学数学二年级以上教材中都有编排,小学阶段共10个单元。《数学广角》教学,既能考验教师对新课标的把握程度,也能体现教师对教材的解读驾驭能力。为什么这么说呢?因为《数学广角》教学内容有一定的难度和规律,它要求师生必须具备一定的逻辑思维和思辨能力。但在听课过程中,通常发现,教师对教材内容本身理解不到位,所以在讲解时,就更谈不上条理性和逻辑性,难点突破更是无从下手,一节课下来,学生仍是一头雾水。 “Mathematics wide-angle” in the PEP primary school mathematics textbooks are arranged above the second grade, a total of 10 primary units. “Mathematics wide-angle” teaching, both to test the teacher’s grasp of the new curriculum standards, but also reflect the teacher’s ability to interpret the teaching materials. Why do you say that? Because of “mathematics wide-angle” teaching content has a certain degree of difficulty and law, which requires teachers and students must have some logical thinking and speculative ability. However, during the lectures, teachers usually find that the contents of the teaching materials themselves are not well understood. Therefore, when explaining, the more logical and logical, the more difficult it is to break through the difficulties and the students are still off one lesson Fog water.
