科学课程标准指出:“亲身经历以探究为主的学习活动是学生学习科学的主要途径,科学课程应向学生提供充分的科学探究机会,使他们像科学家那样进行科学探究。”事实上,每一位学生都具有不同的学习潜能,能够依靠自己获取知识,学习最终要成为学生“自己的事”。笔者下面对在科学课中的“六能六不”进行阐述。一、学生能操作的实验教师不演示科学教材中的实验基本上都将操作步骤描述得很清楚,很多都配有插图,因而有些实验不需要教师进行演示。教师只要把注意点强调一下就行(特别是关于安全方面的),尽量让学生自主完成实验。因为一个实验经教师演示后再让学生去做,虽然实验过 The science curriculum standard states: “Learning through inquiry-based learning is one of the primary ways students learn about science, and science curricula should provide students with ample opportunities for scientific inquiry and make them as scientifically as scientists do.” “In fact, Each student has a different learning potential, can rely on their own access to knowledge, learning eventually to become a student ”own thing “. The author below in the science class ”Six can not do " to elaborate. First, the students can operate the experimental teachers do not demonstrate science textbooks in the experiment are basically the operation steps are described very clearly, and many are equipped with illustrations, and therefore some experiments do not require teachers to demonstrate. As long as teachers emphasize the point of attention on the line (especially on the security), try to allow students to complete their own experiments. Because an experiment by the teacher to allow students to do after demonstration, although the experiment
