在实际生活中我们却发现一些在学校内反应迟钝的孩子,出了校门在购物等实践中变得灵活机智,而一些在校品学兼优、出类拔萃的孩子出了校门却呆若木鸡,没有办事能力。这到底是为什么呢?我认为这种现象的症结就是数学知识与实际生活严重脱节。而解决它的办法就是在数学课堂教学中加强数学知识与生活实际的联系,体现“数学源于生活,用于生活”的思想。从学生已有的生活经验出发,学习新知、探索新知,让数学走进学生的生活。 In real life, we find that some children who are unresponsive in school are out of school. They become flexible and tactful in the practice of shopping. Some of the best students in school are outstanding at school. However, they are out of school and do not have the ability to work . What exactly is this? I think the crux of this phenomenon is the serious disconnect between mathematical knowledge and real life. The way to solve it is to strengthen the connection between mathematics knowledge and life in mathematics classroom teaching and embody the thought of “mathematics comes from life and life”. Starting from students ’existing life experience, learning new knowledge, exploring new knowledge and making mathematics into students’ life.
