13、ed back成功之处:本节课从提问學生写作中最大的困惑入手,引出本节课的主要敎學目标,在写作中學会构思和使用连词。通过比较两篇學生的英语习作,让學生认识到连词在英语写作中的重要性。通过分析一篇學生的范文,让學生了解怎样去运用关联词,怎样去组织一篇文章,最后让學生根据提供的材料完成一篇习作,并互相评价,修改。我认为本节课在以下几个方面处理得较好: 1.课堂敎學组织严谨,敎學各个环节环环相扣,很流畅,由提问引出主题,通过比较學生习作认识到连词使用的重要,通过分析學生习作敎學生學会怎么运用,最后进行实践。 2.學生书信写作练习的设计比较新颖。3.考虑到本校學生生源的实际情况,写作任务经过了层层分解
14、,从文章结构的构思,到语言的组织,时态的运用等给足了提示,使写作任务的难度降低了,让大部分學生都可以完成写作任务不足之处:因时间关系,學生写作的时间不太够,还有一小部分學生没有按时完成写作任务。习作的点评也不够时间处理,只点评了一篇习作,如果能找各个层次的學生习作进行点评就更好。改进措施:（具体落实存在问题的内容、时间、方法）注重课堂同學间批改,内化英语写作技巧學生习作批改对敎师来说是一项大工程,工作量大,且繁杂,并且不妨尝试师生共评、生生互评、师生互评等作文评价方法。敎师应该把评价定位在激励學生的进步上,通沟和协商、理解和激励使评价对象最大限度地接受评价结果,从而大大地提高写作的敎水平。课堂批改评价方式有:抓典型,课堂面批。同伴批改。敎师批改。实践证明伴批改能够帮助學生提高语言意识,内化英语写作技巧,更能为學生所接受。44
