小学科学课是以探究为核心的,探究是科学学习的方式,更是科学学习的目标。因此,科学课中实验过程应是科学教学的重要环节。但是,科学实验课也是科学老师比较难以驾驭的课。因为实验本身就是一个比较复杂的过程,许多不定因素会导致实验中生成一些意想不到的问题。有些实验课,尤其是一些需要用数据来说明结论的实验,由于操作不当而造成数据偏差,使实验结果与正确结论出现混乱, Primary science class is to explore as the core, inquiry is the way of scientific learning, but also the goal of science learning. Therefore, the experiment process in science class should be an important part of science teaching. However, scientific experiments are also more difficult for science teachers. Because the experiment itself is a complex process, many uncertainties can lead to some unexpected problems in the experiment. Some experimental courses, especially some experiments that need data to illustrate conclusions, caused data deviation due to improper operation, confused the experimental results with the correct conclusions,
