实验是小学科学教学的主要内容,是科学探究的过程,要开展有效的科学课堂教学,就一定要抓住科学学科“以实验为基础”的基本特征,上好每一节实验课。下面从科学实验的四个组成部分入手,谈谈如何上好一节高效的实验课。一、实验设计1.明确实验目的。既可以直接告诉学生实验目的,也可以让学生根据课题提出要探究的问题,教师根据学生的提问,引导学生明确实验目的,还可以根据课题的重点词明确实验目的。2.确定实验基本方法。在了解实验目的的基础上,确定实验基本方法。比如在证明物体在水中的沉浮与物体的体积和轻重
Experiment is the main content of science teaching in primary schools and the process of scientific inquiry. To carry out effective scientific classroom teaching, we must grasp the basic characteristics of science subject "experiment-based The following four parts from the scientific experiment to start, talk about how to make a good and efficient experimental class. First, the experimental design 1. Clear experimental purpose. Can tell students the purpose of experiments directly, but also allow students to ask questions to explore according to the subject, teachers according to the students’ questions, guide students to clear the purpose of the experiment, but also can be based on the key words of the subject clear experimental purpose. 2. Determine the basic method of experiment. On the basis of understanding the purpose of experiment, determine the basic method of experiment. For example, to prove the object in the water ups and downs and the object’s volume and severity
