小学生“量感”现状分析及其培养策略研究

Current Situation Analysis and Cultivation Strategy Research of Primary School Students'Sense of Quantity

长期以来,小学数学教学中出现“数感”与“量感”的混淆,比较突出的是“数感”与“量感”均归为“数感”,而无“量感”,导致小学生分不清度量单位,无法对其准确进行大小比较,极不利于小学生“量感”的培养。培养小学生“量感”的主阵地在课堂,因此要充分发挥度量单位教学的重要作用,立足小学生的认知基础和生活实际,巧用情境设置认知冲突,深度体验提升感知能力,重视过程探究知识形成,强化联系促进学科融合,借助技术突破“量感”局限,抓住一切可以利用的机会,促进学生“量感”的发展。

For a long time,the primary school mathematics teaching in the“sense of number”and“sense of quantity”confusion,more prominent is“sense of number”and“sense of quantity”are classified as“sense of number”,and no“sense of quantity”,leading to the primary school students’confusion between the unit of measurement,which can not accurately size comparison,very conducive to the cultivation of pupils“sense of quantity”.The main front of cultivating primary school students’“sense of quantity”is in the classroom.Therefore,we should give full play to the important role of measurement unit teaching.Based on the cognitive basis and actual life of primary school students,we should skillfully use the situation to set cognitive conflicts,enhance the perception ability through in-depth experience,attach importance to the formation of process exploration knowledge,strengthen the connection to promote the integration of disciplines,break through the limitations of“sense of quantity”with the help of technology,and seize all available opportunities to promote the development of students’sense of quantity.
