“问题提出”引领下的小学数学教学探微——以“多边形的面积”单元教学为例

Micro Exploration of Primary School Mathematics Teaching under the Guidance of Problem Presentation——A case study of the teaching of the area of polygons

当前小学数学课堂形态常体现出,“静悄悄的课堂”与“闹哄哄的课堂”两种现象。依托“问题提出”展开的数学教学与数学学习,不仅能弥合两种课堂的消极裂痕,也能为,教师提供新的教学视角,为学生展示新的学习方式。就此,以“多边形的面积”教学为例,可在旧知新识的联结中,在学科认知的进阶中,在思维认知的节点处,在学习情境的建构中引导学生提出问题,走向有意义的倾听与沉默。

The current form of primary school mathematics classrooms often reflects two phenomena:quiet classrooms and noisy classrooms.This paper believes that mathematics teaching and learning based on problem presentation can not only bridge the negative gap between the two types of classrooms,but also provide teachers with new teaching perspectives and show students new learning methods.Taking the teaching of the area of polygons as an example,it is proposed that students can be guided to raise questions in the connection of old and new knowledge,in the advancement of subject cognition,at the nodes of thinking cognition,and in the construction of learning context,leading to meaningful listening and silence.
