SectionC 教学反思教学反思 新课改倡导人文教育，强调课程要促进每个学生身心健康的发展，培养学生良好的品 质和终身学习的能力，新课改提倡交流与合作、自主创新学习，课程改革的成败关键在于 教师，教师是课程改革的实施者，因此我每次备课都会问自己是否解决了两个问题：1、我 是否起了主导作业，充分引导学生说；2、学生是否为主体，得到充分的机会说。 本节课也依照这两个原则进行备课的。本节是阅读课，主要思路有二：其一把阅读课 情节化，让传统的静态阅读动态化，充分引导学生去说，想说。其二是设置多种情景，让 学生在趣味的活动中自然而然地接受新知识，从而提高学生学习英语的兴趣。 1、用学生熟悉的老师和学生，创设各种情景，鼓励学生大胆地说英语，对他们在学习 过程中犯的错误采取宽容的态度. 2、在教学过程中注重学生的听、说、读、写综合能力,鼓励他们大胆的说并运用到实 际中去. 3、创造条件让学生能够发现他们自己的一些问题，并自主解决问题。 本节课上完后，基本实现预期设定的目标。 但是作为英语教师，我任重而道远。不但要成为课堂教学中的主要载体，还有必要在 新一轮的教学改革中充当教研的先锋。边教学，边研究，成为专家型，学者型的教师。同 时在具体的英语教学中，还要注意充当不同的角色。既要当学生的教练员，又要当学生的 陪练员，有时还是学生学习中的伙伴。应当说，在新课程标准下，对英语教师的要求是越 来越高了。我会一直探索！ Unit 4 Amazing Science Topic 1 When was it invented?
