观察是一种有目的、有计划、有准备、积极思维、主动参与的知觉过程,在几何知识学习中起到重要的作用。在苏教版六年级数学上册《表面涂色的正方体》的教学中,学生需要通过观察多个表面涂色的正方体,从而归纳出数学规律。本节课的归纳法主要以数学知识为载体,通过数学概念的形成和建立过程、数学规律的归纳和总结过程、数学问题的分析和解决过程来体现。教师依据数学教材的特点和学生的认知规律,围绕数学思想方法的要求,有计划地组织观察活动,注重对学生进行归纳法的训练,这对于提高学生的数学素质和数学能力非常有益。
Observation is a purposeful, planned, prepared, positive thinking, active participation in the process of perception, learning in the geometric knowledge plays an important role. In the sixth edition of the Sujiao edition of mathematics on the surface of the “painted square” teaching, students need to observe the surface of a number of painted squares to summarize the laws of mathematics. The inductive method in this lesson mainly takes mathematical knowledge as the carrier, which is embodied through the process of the formation and establishment of mathematical concepts, the generalization and summarization of mathematical laws, the analysis and solution of mathematical problems. Based on the characteristics of mathematics teaching materials and students’ cognitive rules, teachers organize the observation activities in a planned way focusing on the requirements of mathematical thinking and methods, and pay attention to the training of students’ induction. This is very beneficial for improving the students’ math and math ability.
