教学重难点:
帮助基础较弱的学生提高略读、关键词等阅读技能。
帮助学习能力较强的学生在完成基础的理解任务之外,提升其自主学习能力和自我拔高能力。
如何以阅读课为依托,全面训练学生的听、说、读、写综合能力。
教学方法:
本课我将结合情境教学法和任务教学法,在教学中引导学生逐步完成预设的学习任务。
1、情景教学法是指在教学过程中,教师有目的地引入或创设具有一定情绪色彩的、以形象为主体的生动具体的场景,以引起学生一定的态度体验,从而帮助学生理解教材,激发学习兴趣。
2、任务型教学法:让学生在课堂活动中获得知识,形成技能。任务完成得过程,就是知识转化的过程。任务要设计合理、形式多样并容易评价。
学法渗透:
1、自主学习:通过自学完成基础性任务,体现学生主体地位。
2、合作探究学习:完成拔高性学习任务,帮助学生进一步提高合作学习能力,培养其合作意识、竞争意识和分享态度。
教学资源
1、教师精心编写的学案:Learning Aid
2、PPT课件
3、教师自己的录音材料
4、教师准备的海报设计
5、课堂自我评价、小组评价表
