小学科学新课程标准中明确提出小学生科学概念的获得主要采用探究的方式,而探究需要借助有结构的材料。因此,我们要对仪器室现存材料进行整理、归类,同时,对现有不适宜的材料及时清理,替换适宜的材料,创建起科学实验材料库。并且要在教学过程中对材料进行优化升级,以更好地帮助学生建构科学概念。 The new curriculum standard of primary science clearly put forward that primary school students acquire the concept of science mainly by means of inquiry, and inquiry needs to use structured materials. Therefore, we need to organize and classify the existing materials in the instrument room. At the same time, we should promptly clean up and replace the suitable materials and create a scientific experimental material library. And in the process of teaching material optimization and upgrading, in order to better help students construct the concept of science.
