【摘要】：新课程改革对小学估算教学提出了明确的目标和具体的要求,但在教学实践中仍存在估算教学目标不明确、学生估算意识淡薄,估算教学过程难把握、学生优化估算方法困难,估算教学评价单一、学生估算策略运用不灵活等问题。培养小学生的估算能力,提高小学估算教学实效的主要策略有三:一是全面渗透估算教学思想,强化估算意识,促进学生对估算价值的理解;二是注重将估算教学与生活链接,精选估算例题,丰富学生估算解决问题的体验;三是鼓励学生交流估算的方法,优化估算策略,合理地评价估算的结果。
[Abstract]:The new curriculum reform has put forward clear goals and specific requirements for the estimation teaching in primary schools. However, in teaching practice, there are still some problems, such as unclear teaching objectives, weak students' awareness of estimation, difficulty in grasping the process of estimating teaching, and difficulties in optimizing the estimation methods of students. The evaluation of estimation teaching is simple and the students' estimation strategy is not flexible. There are three main strategies to cultivate the students' estimation ability and improve the teaching effect of estimating teaching in primary school. The first is to fully infiltrate the idea of estimating teaching and strengthen the consciousness of estimating. Promote students' understanding of estimating value; second, focus on linking estimation teaching to life, select estimation examples, enrich students' experience in estimating and solving problems; third, encourage students to exchange estimation methods and optimize estimation strategies. Evaluate the results of the estimation reasonably.
