初中英语教学案例
一.《英语课程标准》提出学生的发展是英语课程的出发点和归宿.英语课程在目标设定,教学过程,课程评价和教学资源的开发等方面都突出以学生为主体的思想.课程实施应成为学生在教师指导下构建知识,提高技能,磨砺意志,活跃思维,展现个性,发展心智和拓展视野的过程.教师应在教学过程中有意识的加以适当的引导,激发学生对于掌握一门外语的迫切需要性,引发他们学习的积极性和主动性,充分发挥学生在课堂上的主体作用.一堂成功的课,应该让学生自始至终掌握主动权,教师只是充当"组织者" "促进者,""合作者,""咨询者,""参与者,""引导者,""顾问"等多种角色,最大限度地给学生提供参与的机会,学生的主体性得到了体现,自然就产生了求知和探究的欲望,也就会把学习当作一件乐事.但在课堂上经常会发生一些偶发事件.偶发事件是指课堂教学中没有预先预见而在教学过程中出现的事件.由于偶发事件具有偶然性,突变性,多样性和不易控制等特点,很多老师非常担心课堂教学中偶发事件的发生.偶发事件,更多时候成为课堂教学的干扰性因素,甚至成为教师教学心理中的阴影.其实,偶发事件看似与教学目标无关,或是影响课堂教学,但只要我们教师处理得当,因势利导,以变应变,恰当运用,不但可以保证课堂教学的顺利进行,而且还可以将之转化为有价值的课堂教学资源,成为课堂教学的新亮点.
