教材是教师组织课堂教学的依据,是教师教学和学生学习的主要载体,对培养学生的智力思维有着决定性影响。一、突出知识核心,促进知识条理化教师要善于将教材提供的内容重组,突出知识结构核心,使知识系统化、条理化,再进行教学。如在教学“梯形的认识”一课中,其知识点有梯形的定义、各部分名称、直角梯形和等腰梯形的特征等几部分内容。教学时要紧紧抓住“梯形定义”这个知识结构的核心,串联各个知识点,使知识系统化。二、运用概念法则,形成知识网络小学数学知识内容之间前后联系密切,相互呼应,相辅相成。教师传授知识时,要注重引导学生揭示知识之间的内在联系,掌握其相互转化的规律和实质,使它们脑子里“散装”的知识形成网络。如在教学“整数的四 Teaching materials are the basis for teachers to organize classroom teaching, which is the main carrier of teacher teaching and student learning, which has a decisive influence on the cultivation of students’ mental thinking. First, highlight the core of knowledge and promote the rationalization of knowledge Teachers should be good at reorganizing the content provided by textbooks, highlighting the core of knowledge structure, so that knowledge of the system, organized, and then teaching. As in the teaching ”trapezoid “ lesson, the knowledge points are trapezoidal definition, the name of each part, right trapezoid and isosceles trapezoid characteristics of several parts. Teaching should firmly grasp ”trapezoidal definition “ the core of the knowledge structure, the series of knowledge points, the knowledge system. Second, the use of the concept of law, the formation of knowledge network Primary and secondary mathematics before and after the close contact between content, echo each other, complement each other. When teachers impart knowledge, they should pay more attention to guiding students to reveal the internal relations among knowledge, master the law and essence of their mutual transformation, and make the knowledge of ”bulk “ in their mind form a network. As in teaching ”Integer of four
