本文结合教学实践,谈谈在新课程理念下对小学数学课堂教学的几点思考。一、贴近现实生活设计数学活动生活中处处有数学,关键是教师要善于发现、挖掘生活中的数学问题,与学生的实践相结合,设计具有科学性、趣味性、思考性和可探索性的数学活动,有利于学生的发展。例如自编教材“数字的妙用”,这节课就是以数字编码在生活中的应用为例设计教学的。“身份证”人人皆知,但由于其中含有数字编码知识,绝大多数人对“身份证”又不了解。抓住这一能服务于教学的生活实例,设计数学活动,让学生在实践中发现数学问题和数学思想。在学生眼中,“身份证”这个贴近生活包含有科学知识的东西非常新鲜有趣,表现出强烈的求知欲望,因而积极地参与整个活动过程,充分体现了学生的主体性。
In this paper, teaching practice, to talk about the concept of the new curriculum of primary school mathematics classroom thinking. First, close to the real life design Mathematics activities Everywhere in life there is a math, the key is that teachers should be good at discovering, mining mathematical problems in life, combined with the practice of students, the design of a scientific, interesting, thoughtful and exploratory Mathematical activities are conducive to the development of students. For example, self-compiled textbook “magical digital” This lesson is based on the application of digital coding in life as an example of teaching design. “ID cards” are well known, but most people do not know about “identity cards” because they contain digital coding knowledge. Seize this can serve the teaching of life examples, mathematical activities designed to allow students to find in practice mathematical problems and mathematical thinking. In the eyes of students, the “ID card”, which is close to life and contains scientific knowledge, is very fresh and interesting. It shows a strong desire to seek knowledge. Therefore, it actively participates in the entire activity process and fully reflects the students’ subjectivity.
