如何走进新课程，如何建构新课程有效课堂教学，是当前我们每位新课程教师所面临的严峻课题，打造优质高效的课堂是我们每一位老师的责任。在课后我进行了及时、认真、深刻的反思，透过课堂教学反应出来的现象，努力探索教学规律，深刻总结教学中出现的问题。希望能抓住教学中的主要问题，及时调整、改进自己的教学行为，不断总结教学经验，提高自己的教学水平和业务能力。
本节课的不足之处：
1 .课堂导入的图片和视频感觉一定可以引起了学生极大的兴趣，给予学生视觉上的冲击，在一定程度上是能起到调动学生积极性的作用，但好像只是欣赏图片，观看视频，没有考虑播放视频的目的何在。
2. 在reading的细读部分的时间超过预算，导致读后活动完成得有点仓促。这一活动本应给学生充足的时间，让学生充分地参与，掀起课堂教学的高潮，让学生获得学习、发明的喜悦感和成功感。
3. 在课堂教学的展示部分学生表现积极踊跃，对于他们的表现也都给出了相应的评价，但是没有选出优胜小组。但是小组之间的互相欣赏与评价体现的不是很明显。
今后教学的计划和打算：
1. 不断地向老教师学习，来弥补自己的不足之处；不断接触学习新的教学理念和教育教学观，以便更新自己的教学思想，不断历练和完善自我，努力提高自身的素质和教学修养，让自己始终走在教育的最前沿。
2. 在课堂上想办法充分调动学生学习的积极性，让学生充分地参与到课堂教学中，以此来提高课堂效率。可以适当地创造机会让学生参与竞争，在一定程度上培养学生的竞争意识，给学生一定的成就感。
