小学科学是一门以实验为基础的学科。而小学生的实验操作技能还没有完全形成,在教学中,教师如果能适当地对学生实验操作的方法、步骤等进行指导,那就可以提高学生实验的有效性。本文认为在小学科学课堂教学中主要可以运用演示实验法、“温馨提示”法、提问法、利用“实验记录单”法等四种方法。 Primary science is an experiment-based discipline. The experimental skills of primary school students have not yet been fully formed. In teaching, if teachers can properly guide students on the methods and steps of experimental operation, it can improve the effectiveness of students’ experiments. This paper argues that in the primary science classroom teaching, we can mainly use the four methods of demonstration experiment method, “warm tip” method, questioning method and “experiment record sheet” method.
