笔者观摩了课改以来的一系列教学研究、展示活动,深感数学课堂教学发生了以下几个方面的深刻变化: 一、课堂教学体现“生活化” 生活中到处有数学,到处存在着数学思想,关键是教师是否善于结合课堂教学内容,去捕捉“生活现象”,采集生活数学实例,为课堂教学服务,在数学生活化的学习过程中,把所学的知识运用到生活中是学习数学的最终目标,也是学习“有价值”数学的生动体现。教学中,应再现生活情景,引导学生回归生活空间,在生活空间中实践、在生活实践中感知,激发学生自觉地应用所学知识解决生活中相关的问题,让学生在生活实践中提高解决问题的能力。如:让学生比较使用“液化气”和“电”哪个便宜?如何设计校园绿化方案?怎样筹备装修事宜?模拟购物、存款等……这样的教学安排,以直观性、开放性、体验性而更贴近
After observing a series of teaching research and demonstration activities since the curriculum reform, the author deeply felt that profound changes have taken place in the following aspects: First, classroom teaching embodies mathematics everywhere in “living life” , The key is whether teachers are good at combining the contents of classroom teaching to capture the “phenomenon of life”, collecting examples of life mathematics, teaching services for the classroom, in the process of mathematical life learning, to apply the learned knowledge to life is to learn mathematics The ultimate goal, but also a vivid manifestation of learning “valuable” mathematics. Teaching, should reproduce the life scenarios, guide students back to living space, practice in the living space, perceived in life practice, inspire students to consciously apply their knowledge to solve life-related problems, so that students in life practice to improve the problem-solving Ability. Such as: let students compare the use of “liquefied petroleum gas” and “electricity” which is cheaper? How to design campus greening program? How to prepare for decoration? Simulation of shopping, deposits, etc ... ... Such teaching arrangements, intuitive, open and experiential Closer
