《数学课程标准》强调“从学生已有的生活经验出发,让学生亲身经历将实际问题抽象成数学模型并进行解释与应用”的过程。为促进学生数学实践能力的有效提升,笔者尝试了“师生备学”理念,即教师充分挖掘教材内容,创设实践的机会与情境,让学生在操作中积累生活经验,在“创作”中升华情感态度,在测量中学习数学思维,从而引领学生走向“体验学习”的新天地。一、动手操作,积累生活经验人们常说:孩子的智慧长在手指间。的确如此,学生通过动手操作,可以发现很多有趣的现象,他们内心产生的好奇和思考,都会
The standard of mathematics curriculum emphasizes the process of “starting from the students’ existing life experiences and letting students experience the abstraction of practical problems into mathematical models and their interpretation and application”. In order to promote the students’ ability of maths practice effectively, the author tried the idea of “preparing students and teachers”, that is, teachers fully exploit the contents of teaching materials and create opportunities and situations of practice so that students can accumulate experience of life in operation. “In the sublimation emotional attitude, measurement in learning mathematical thinking, leading students to ” experience learning "new world. First, hands-on operation, accumulation of life experience People often say: the child’s wisdom grows in the fingers. Indeed, students can find many interesting phenomena through their hands-on operation, curiosity and thinking generated by their hearts,
