SectionSection A A 教学反思教学反思 新课程改革，是一次深刻的改革。新课改倡导全人教学，强调课程学要促 进每个学生身心健康的发展，培养学生良好品质的终身学习的能力；新课改倡 导建设性学习，注重科学探究的学习，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。作为教师我必须做好充 分的准备，学习新课程改革理论，更新教学观念，迎接新课改的挑战。本节公 开课是一节比较平实、朴素的课，不像我们平时的观摩课那么富有新意，但还 是有一些地方值得我反思和采纳的，现归纳如下： 下面就简单总结一下我这 节英语教学工作的利弊。 利：我在课堂活动中采取鼓励学生学习的方法，当学生正确回答问题时， 我常常进行鼓励，这是帮助初学者克服英语学习的良好方法。而且任何鼓励都 会使学生感到高兴，我在课堂上大胆使用鼓励，可以鼓励全班，也可以鼓励某 一小组或某一学生。当学生在开展个人活动、小组活动时，我主动到学生中间 去，鼓励和帮助某一个、两个学生或某一组学生，这种做法不但能让学生积极 的加入到课堂活动中来，还能锻炼他们的口语和听说表达能力。 而针对学生 的书面作业，我也经常给予鼓励，不仅可以写上“Good！Very good!”等，还可 以贴上一张表示鼓励的小粘贴画。对于学生书面作业中的错误能给予及时纠正， 让学生感到你在意他们的书面作业，从而让他们渐渐的对学习英语产生兴趣， 进一步提高他们的英语成绩。 弊：我在今后英语教学活动中应该注意以下几点： 、坚持英语教学的实践性原则，改变过分重视语法和词汇知识的讲解 与传授； 、防止过分强调模仿、死记硬背、机械操练的教学倾向； 、倡导语言知识教学和技能相结合的、开放的、互动的学习模式； 、关注学生有困难或性格内向的学生，尽可能多的为他们创造语言的 机会； 、引导学生在学习过程中，进行自我评价，并根据需要调整自己的学 习目标和学习策略等等。 总之，新课程改革不是纸上谈兵，必须要与实践相结合，努力学习，积极 进取，积极参与课程改革，在改革中不断学习，不断实践，不断反思，这样才 能把新课改落到实处。虽这短短的一次课并不能把工作做好，也不能提高学生 们的学习兴趣，但我会在今后的工作中慢慢的总结，细心地处理学生碰到的问 题，根据新课改的要求把工作做完整，做一位名副其实的好老师！! !谢谢
