High? 误往往不太敏锐，常常视而不见;而对他人的错误却相当敏感。这样同桌交换或同组交换，即可满足学生的好奇心，激发其修改兴趣，又可营造学生互相帮助、互相竞争的良好气氛。 6. 这节课也存在一些问题。例如，在问题的设置上，还是不能兼顾到所有学生。所以，还有很多改进和有待提高的地方。例如，如何让学生的自主和探究学习更加深入,如何照顾到学生的个别差异,如何使那些对学习不感兴趣、基础差、注意力不集中的学生也自始至终较积极地参加小组活动, 从高效课堂的实施过程中，我收获了很多。总结成几句话就是:给学生一些权利，让他们自己去选择;给学生一些机会，让他们自己去体验;给学生一些困难，让他们自己去解决;给学生一些问题，让他们自己去思考;给学生一些条件，让他们自己去创造;给学生一些空间，让他们自己去探索;给学生一些时间，让他们自己去享受。 period, transpiration, water requirements, and is one of the most crucial irrigation under soil water retention properties ofthis turned green before the rainy season.
