李代桃僵——生活材料的课堂使用

Palming off Substitute for the Real Thing——Classroom use of living materials

在科学课堂上,运用"李代桃僵"的策略是讲究以某种价格较低的材料替代较为精密的仪器或实验器材,取得较好的教学效果。选择科学探究材料时还要考虑到学生的兴趣、知识经验水平及活动本身的设置等诸多方面。有效的科学实验教学,可以培养学生的实验能力和创新精神,使他们养成严谨求实的态度和追求真理的科学精神,形成科学的价值观,加深其对科学事实的理解。

In science class,the strategy of"Li Dai Tao Jiang"is to replace the more precise instruments or experimental equipment with some cheaper materials,so as to achieve better teaching effect.When choosing scientific inquiry materials,we should also consider the students’interest,knowledge and experience level and the setting of the activity itself.Effective scientific experiment teaching can cultivate students’experimental ability and innovative spirit,make them form rigorous and realistic attitude and scientific spirit of pursuing truth,form scientific values and deepen their understanding of scientific facts.
