【摘要】：新課程改革對小學(xué)估算教學(xué)提出了明確的目標(biāo)和具體的要求,但在教學(xué)實踐中仍存在估算教學(xué)目標(biāo)不明確、學(xué)生估算意識淡薄,估算教學(xué)過程難把握、學(xué)生優(yōu)化估算方法困難,估算教學(xué)評價單一、學(xué)生估算策略運用不靈活等問題。培養(yǎng)小學(xué)生的估算能力,提高小學(xué)估算教學(xué)實效的主要策略有三:一是全面滲透估算教學(xué)思想,強化估算意識,促進(jìn)學(xué)生對估算價值的理解;二是注重將估算教學(xué)與生活鏈接,精選估算例題,豐富學(xué)生估算解決問題的體驗;三是鼓勵學(xué)生交流估算的方法,優(yōu)化估算策略,合理地評價估算的結(jié)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.
