科学实验的主体不是教师,也不是实验教材,而应是学生,在实验中要让学生主动生成.本文通过“质量的测量”的不同教法得到启示:只有把科学实验的主体定为学生,才能激发学生学习的兴趣,提高他们的探究能力和创新能力.本文同时分析了现在大部分学生对实验失去兴趣的原因,以及如何在科学实验中落实学生的主动权.

Pre-concept in classroom teaching is the concept formed from real life experience by students,and its education value should be developed.Pre-concept can be roughly divided into assimilated pre-concept and alienated pre-concept.Teachers should learn to respect students and create easy atmosphere for inquiry learning under the new curriculum standard;Questions and hypothesis should be proposed to make students fully expose pre-concept;Experiments are needed to get the facts and evidence,and make pre-concept transform to scientific concept;Evaluation is also important in this process.
