摘要科学是一门以实验为基础,以形象直观的现象来传播知识的学科。实验则是学习科学的重要方法。在新课程模式下强调以学生为本,要达到这个要求就更离不开实验的支持。然而在现在的教学活动中,有许多教师忽略了演示实验的重要性和必要性,抱着“可做可不做”的态度教学。笔者结合在杭州市丁兰实验中学的实习经验,针对“光的反射规律”这一探究实验,提出了自己的见解和看法,试图提高演示实验的实效性;并为探究演示实验确实有效帮助教师提高教学质量,笔者在绿城育华亲亲学校展开了实证调查,最终得出结论:演示实验能够调动学生上课的积极性,在实验的过程中将抽象的知识直观化,同时,演示实验还能够培养学生的观察能力,激发学生去思考和解决现象的本质原因。44165

Science is a discipline on the basis of experiment, which spreads knowledge by visual phenomena. The experiment is an important way to learn science. The new curriculum standards emphasize that the students are first. So it can’t meet this requirement without the support of the experiment. In the present teaching activity, however, there are many teachers ignore the importance and necessity of the demonstration experiment, holding the "can do not do" attitude of teaching. According to the author’s experience in Hangzhou dinglan experimental middle school, the author put forward her own opinions and views on the principle of light reflection is the exploring experiment, trying to improve the actual effect of demonstration experiment; And the author opened the empirical investigation in greentown yuhua qinqin school, in order to explore the demonstration experiment is to help teachers to improve teaching quality effectively, finally draw the conclusion: the demonstration experiment can arouse the enthusiasm of students in class, in the process of experiment, the abstract knowledge visualization, at the same time, the demonstration experiment can develop the students' ability of observation, stimulate students to think and solve the phenomenon of the nature of reason.
