认知的结构观强调学习是学生内部认知结构的形成和重组的过程,有意义的学习过程就是符号代表的新知识与学生认知结构中已有的适当观念建立的非人为的实质联系。教学中,教师一方面应该把握数学知识的核心本质和蕴含的数学思想,另一方面也要充分考虑学生原有的经验,包括生活经验、知识经验、思维方式等,在这两者之间建立对话的桥梁,开展适切的数学活动,使学生经历学习真正发生的过程,准确地掌握数学概念,构建数学知
The cognitive structure emphasizes that learning is the process of the formation and reorganization of students’ internal cognitive structure. The meaningful learning process is the non-human substantive connection between the new knowledge represented by symbols and the existing appropriate concepts in the cognitive structure of students. In teaching, teachers should grasp the core essence of mathematics knowledge and the mathematical thought contained on the one hand, and on the other hand, they should give full consideration to the original experience of students, including life experience, knowledge experience, way of thinking and so on, Dialogue bridge, to carry out appropriate mathematical activities, so that students go through the process of learning what really happened, accurately grasp the mathematical concepts, to build mathematical knowledge
