课改实施已有多年,经过这些年来的实践和探索,对于操作在课堂教学中的特点、功能及作用进行了一些深刻的思考,有了一点全新的认识。课堂实践操作活动是一种给学生提供思考和弄懂他们所不易弄懂的问题的一种主动学习活动。在课堂教学中能成功地运用它,易于激发学生学习兴趣,便于在感性材料基础上建立表象,有助于理解新知识,为教师传授新知起到了事半功倍的效果,达到优化数学课堂教学的目的。 After years of practice and exploration, the curriculum reform has been carried out for some years. After some years of practice and exploration, it has made some profound thoughts on the features, functions and functions of the operation in the classroom teaching, with a new understanding. Classroom practice is an active learning activity that gives students the ability to think and understand what they do not understand. The successful use of it in classroom teaching can easily arouse students’ interest in learning, facilitate the appearance of images on the basis of perceptual materials, help to understand new knowledge, play a multiplier effect for imparting new knowledge to teachers, and achieve the goal of optimizing mathematics classroom teaching.
