在数学教学中,动手实践是非常有效的学习方法之一,教师可以倡导学生通过“做数学”的方式来生成对问题本质的深层理解。这里的“动手实践”应是指从动手开始的全身心参与式实践活动。从数学操作活动的外显层面看,不只限于动手的直观操作,还应包括动笔的符号操作、动口的言语操作等多感官参与的实践活动。对于小学生而言,动手 In mathematics teaching, hands-on practice is one of the most effective learning methods. Teachers can advocate students to create a deep understanding of the nature of the problem through “doing math.” Here “hands-on practice ” should refer to wholeheartedly participatory practice starting from the beginning. From the perspective of the mathematical operation of the explicit level, not only for hands-on visual operation, but also include the symbolic operation of the pen, verbal actions and other multi-sensory participation in practical activities. For elementary students, hands-on
