《数学课程标准》中明确指出:动手实践、自主探索与合作交流是学生学习数学的重要方式。学生学习方式的变革必然引发课堂教学的改变,如何落实学生新的学习方式,发挥最大的学习效益,就是教师必须要思考的问题。本文选择动手实践这一学习方式,结合笔者教学实践,从创设有趣的情境,唤起操作的兴趣;设置操作障碍,激发学生操作的动力;选择操作的时机,发挥动手操作的效益三个方面阐述了认识。
“Mathematics curriculum standards” clearly states: hands-on practice, independent exploration and cooperation and exchange is an important way for students to learn mathematics. The change of students’ learning style will inevitably lead to the change of classroom teaching. How to implement the new learning mode and maximize the learning efficiency of students is the question teachers must think. This article chooses hands-on practice of this learning method, combined with the author’s teaching practice, from the creation of interesting situations, to arouse the interest of the operation; to set the operation barrier, to stimulate students’ motivation; to choose the timing of operation, understanding.
