一、概念形成时“增加重力”1.重视概念获得的过程与方式,使概念学习有深度概念教学,就是要让学生经历数学概念的形成过程,达成数学概念的自主建构。在“圆的认识”的教学中,有位教师是这样教的:①智能机器人感应到:足球距离自己30厘米,若用1厘米代表10厘米。足球可能在哪里?用直尺画 First, the concept of the formation of “increase gravity ” 1. Emphasis on the concept of the process and manner of acquisition, the concept of learning a deep concept of teaching is to enable students to experience the formation of mathematical concepts to achieve the mathematical concept of self-construction. In the teaching of “Awareness of the Circle,” one teacher taught this: ① Intelligent robot senses that football is 30 centimeters from itself and 1 centimeter represents 10 centimeters. Where may football be? Draw with a ruler
