在小学科学课教学中,通过循序渐近地训练,让学生像科学家那样,用科学实验的方法,去探索、认识自然界事物的性质和规律,培养他们独立、主动的探索精神和动手实践能力,是引导他们从小爱科学、学科学、用科学的基础环节,也是提高学生科学素质的重要手段。在探究活动中,要特别强调教师在指导上做到适时和适度。一、探究前——适当指导学生准备材料科学课学生实验前材料的准备是科学课有效性学习不可缺少的一部分。尽管它繁琐,尽管它费时费力,尽管它常常会出现这样、那样的不尽人意。但是只要科学老师指导的当, In the teaching of primary science, through gradual and orderly training, students can use science and experiment methods to explore and understand the nature and laws of nature and cultivate their independent and active exploration spirit and hands-on practical ability. Is to guide them from childhood love science, science, science with basic links, but also to improve students’ scientific quality is an important means. In the exploration activities, special emphasis should be placed on the timely and appropriate guidance of teachers. First, the pre-inquiry - Appropriate guidance to prepare students for materials science class Preparation of materials before the experiment is an indispensable part of the effective learning of science class. Despite its cumbersomeness, though it is time-consuming and laborious, it does not always look as good as it often appears. But as long as the guidance of science teachers,
