关照意义:数学教学的价值追求

Care for Significance: The Value Pursuit of Mathematics Teaching

关照意义,即站在教育学的立场思考知识的教育价值,关注知识学习对学生成长的作用。数学知识意义系统内核丰富,包括数学知识、数学思想和数学与人成长之间的关系三个方面,这三个方面构成了数学意义系统的三个层级。之所以要关照意义,是因为意义是数学深度教学的必然要求,是评价学生数学学习的重要尺度。数学教学要实现数学知识的意义,需从以下几方面努力:发挥理解的价值,走进数学知识的内核;契合学生生活经验,建构立体的数学知识结构;提高教师的反思意识,思考数学知识与生活的联系;关注学生的差异,提倡鉴赏性评价。

Care for significance that is standing on the position of pedagogy to think about the education value of knowledge, paying attention to the effect of knowledge learning on the growth of students.The mathematical knowledge system has a rich kernel, including mathematical knowledge, mathematical thinking, and the relationship between mathematics and human growth.These three aspects constitute the three levels of the mathematical meaning system.The reason why mathematics teaching should concern about the meaning is that it is the inevitable requirement of the mathematics depth teaching, and it is also an important measure to evaluate students' mathematics learning.In order to realize the meaning of mathematics knowledge, mathematics teaching needs to make efforts in the following aspects: playing the value of understanding and walking into the core of mathematical knowledge;fitting the students' life experience, and constructing three-dimensional mathematical knowledge structure;improving teachers' reflective consciousness and thinking about the relationship between mathematical knowledge and life;concerning about students' differences and promoting appreciation evolution.
