14、entions” 为话题，合理利用并开发课程资源，为了更好的贴近实际和生活提供力丰富的资源。1. 在这节课的教学环节设计上，从学生在教室内寻找发明，符合新课标的主体性原则，让学生自由组合成几个小组，体现了灵活开放性的课堂。2. 以小组的形式进行教学活动，促进学生互相学习和互相帮助的合作精神。活跃了课堂气氛，调动学生的积极主动性，并与本节任务型的课紧密相连，大大地提高了学生的学习效率，完成教学任务，感受成功。3. 在课堂上通过听说的训练，实现了师生互动，学生互动，整个教学环节，体现了以学生为主体的教学。六自我反思 在这节课中，我采用了情景教学，让学生自主学习和合作学习。在新授单词时与日常生活中的实物相结合，让学生更好地理解单词的含义和记忆。本节课的一个亮点就是利用实物进行教学，大部分学生都懂而且也会说，整个课堂气氛相当活跃，从而学生的积极主动性也就调动起来了。学生的热情很高，效果也很好。我把被动语态放在1a部分讲解，主要是为作准备，因为在这几部分中都是围绕被动语态展开听力训练和对话操练的。所以我觉得放在这里讲解是很有必要的。本节课的内容不是很多，感觉比较好，为以后更好地教学，本人以下几点经验：1. 注重实践，把知识和生活紧密相连。本节课我注重学生实际运用语言和听力能力的培养，根据听力的内容，利用身边的发明进行对话，主要是让学生把课本的知识变成自己的。2.
