随着新课程标准在数学教学中的深入应用,对数学学科教学提出的要求和目标也发生了与时俱进的变化和提升。构建主义学者认为,构建教学活动整体的组成部分主要有教师、学生和课堂环境等,这些组成要素对教学活动过程的设计以及教学方式的运用,产生着十分重要的影响和制约。小学数学教师在新课程标准的要求下,运用行之有效的教学策略和方法,开展课堂教学活动,已成为一个值得深入研究的课题。下面,结合 With the in-depth application of the new curriculum standard in mathematics teaching, the requirements and goals put forward in mathematics teaching have also undergone changes and improvements with the times. Constructivists believe that the main components of the construction of teaching activities are mainly teachers, students and classroom environment. These elements have very important influence and restriction on the design of teaching activities and the application of teaching methods. Primary mathematics teachers in the new curriculum standards, the use of effective teaching strategies and methods to carry out classroom teaching activities, has become a topic worthy of further study.
