数学感知是对数量关系和空间关系的感知,是一切数学活动的起点。数学感知是否充分、精准、深刻,直接关系到后续的数学活动成效。当前教学实践中,由于教学理念的偏失,存在着虚假感知、形式感知、片面感知等不良倾向,制约着数学教学效果。如何让数学感知更加有效呢?我们认为要注意以下“五度”。一、重视创设情境,让感知氛围有热度《数学课程标准(2011年版)》强调:“数学教学活动应激发学生兴趣,调动学生积极性。”数学感知是学生主体积级参与的知情共融过程,是有明显情感倾向性
Mathematical perception is the perception of quantitative relations and spatial relations, is the starting point of all mathematical activities. Mathematical perception is adequate, accurate, profound, directly related to the success of mathematical activities. In the current teaching practice, due to the loss of teaching philosophy, there are some unhealthy tendencies such as false perception, formal perception and one-sided perception, which restrict the effectiveness of mathematics teaching. How to make mathematical sense more effective? We think that we should pay attention to the following “five degrees.” First, attach importance to create a situation, so that the atmosphere has a perceived atmosphere, “Mathematics Curriculum Standard (2011 Edition)” stressed: “Mathematics teaching activities should stimulate interest in students to mobilize the enthusiasm of students.” Mathematical perception is the main level of student participation in the public Process, there is a clear emotional bias
