减轻学生课业负担的重要措施之一是提高课堂教学效率。而小学阶段,巧妙使用数学学具是打造高效轻松数学课堂的重要手段,对提高小学数学课堂教学效率所起的作用不容忽视。一使用学具,有助于促进学生数学概念的形成心理学研究表明,儿童认识规律是“感知——表象——概念”。操作学具符合这一规律,能变学生被动地听为主动地学,充分调动学生的各种感官参与教学活动去感知大量直观形象的事物,获得感性知识,形成知识的表象,并且诱发学生积极探索,从事物的表象中概括出事物的本质特征,从而形成科学的概念。
One of the important measures to reduce the burden on students is to improve the efficiency of classroom teaching. In elementary school, clever use of mathematics is an important way to create efficient and relaxed mathematics classroom, which plays an important role in improving the efficiency of primary school mathematics classroom teaching. A use of learning tools, help to promote the formation of mathematical concepts of students Psychological research shows that children’s cognitive law is “perception - appearance - concept ”. Operational learning tools conform to this principle, can change students passively listening to take the initiative to learn, fully mobilize the various senses of students to participate in teaching activities to perceive a large number of visual images of things, access to perceptual knowledge, the formation of knowledge of the surface, and induce students to actively explore , From the appearance of things summed up the essential features of things, thus forming a scientific concept.
