摘　　要：在教学体系中,实验教学占有非常重要的地位。学习金字塔理论告诉我们,主动式学习的效果要远高于被动式学习,提高学生学习的主观能动性有助于提升实验教学的效果。为了克服传统验证性实验学生做得多、思考讨论少的缺点,以溶液燃烧法合成Y_(2)O_(3):Eu^(3+)荧光材料实验内容的改革为例,探讨通过实验内容的改革增强学生主动参与实验结果分析与讨论的主观能动性,提高实验教学效果的方法。Practice teaching is very important in the teaching system.The learning pyramid theory tells us that the effect of active learning is much higher than that of passive learning,so it will help to improve the effect of practical teaching to improving students’subjective initiative.In order to overcome the shortcomings that students do more and think less in traditional confirmatory experiment,the reform of experimental content has been carried out taking the synthesis of Y_(2)O_(3):Eu^(3+)fluorescent material by solution combustion method as an example.The reforming method of experimental content that can enhance students’active participation in the analysis and discussion of experimental results,and improve the effect of experiment teaching is discussed.
