学情分析

在我校高中阶段，英语学习是不少学生的薄弱点，在各学科中，英语学习的困难居其它学科之首（尤其对男生），导致很多学生对英语学习失去了兴趣和信心，相当一部分同学比较被动或非常被动，甚至放弃了对英语的学习。但这个班的学生英语基础比较好，学习积极性高，朝气蓬勃，求知欲强，在思维上有很强的性。学生能从一般的文字资料中获取主要信息，能针对问题表达自己的见解，同时能与他人合作，解决问题并报告结果，也能够利用一些教育资料进行自主学习。另外，学生的学习能力较强，可以当堂有效地完成学习任务。
效果分析
通过本节课的教学，现对教学效果进行分析：
1. 教学效果显著，学生能够完全地掌握文章内容，不同层次的学生均有收获，有效地达成了教学目标。
2. 学生思维活跃，积极进行合作探究学习，整个课堂学生都能积极地参与到课堂教学中，真正地成为课堂的主人。 3. 师生交流和谐，课堂学习氛围良好。 4. 课堂训练题设计层层深入，检测效果好。
5. 在后面的思考和讨论中，学生们在完成教师设计的教学任务时，
5
也接受了相应的情感教育。
6. 在评价学生展示成果时，还要注意评价语言的丰富性。
教材分析
本单元以Inventors and inventions为话题，旨在通过单元教学，使学生了解发明和发现的区别，了解发明创造的过程和获得专利的条件，学习发明家的成功事例；能灵活运用基础句型描述中外古代和现代发明，谈论不同发明的优缺点及其现实意义；根据不同问题及条件设计、改进发明并阐述自己的观点；能对别人的发明、创造或观点提出意见或建议；并能运用所学知识利用现实生活中有限材料进行发明创造。
