《数学课程标准(2011年版)》指出:“教师应激发学生的学习积极性,向学生提供充分从事数学活动的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法,获得广泛的数学活动经验。”因此,数学课堂中要为学生提供操作的平台,使学生有机会去动手实践,从而理解知识、积累活动经验。那么,在实际教学中,怎样选材最能体现操作表征的优势?怎样提高操作的效率?如何有效地把操作表征内化建构?一、明确目标,精选材料学具操作在小学数学教学中很重
The Standard for Mathematical Curriculum (2011 Edition) states: “Teachers should stimulate students’ enthusiasm for learning and provide students with opportunities to fully engage in mathematical activities to help them truly understand and master basic mathematical knowledge in their own exploration and cooperation and exchange. And math thinking and methodologies. ”" Therefore, the mathematics classroom should provide a platform for students to operate and give students the opportunity to practice in order to gain knowledge and accumulate experiences in activities. So, in practical teaching, how to choose the material which can best reflect the advantages of the operation characterization? How to improve the efficiency of the operation? How to effectively characterize the operation of the internal structure? First, a clear goal, selection of materials learning operation in primary school mathematics teaching weight
