一、教学中常见的小组合作学习模式问题新课程实施中,在我们的化学课堂教学中,经常看到教师采用小组的形式讨论问题或进行实验。如听过的这么一节课:在弱电解质电离平衡教学完后讨论外界因素影响问题时,老师给出这么一个问题:加热稀氨水,溶液中的C(OH-)有什么变化?请你自己设计实验去验证你的结论……于是乎:学生兴趣浓厚,积极性非常高,有的很积极发表见解,有的一声不吭,有的积极动手做实验。一会儿,师示意学生停止了 First, the common group teaching mode of cooperation learning problems In the implementation of the new curriculum, in our chemistry classroom teaching, teachers often see the form of group discussions or experiments. Such as heard of such a lesson: In the weak electrolyte ionization balance after the discussion of the impact of external factors, the teacher asked such a question: heating dilute ammonia, the solution of C (OH-) What has changed? Please yourself Design experiments to verify your conclusion ... Ever since: students interested in a very high enthusiasm, and some very positive opinions, some silent, and some active hands-on experiment. For a moment, the teacher instructed the student to stop
