备课是上好一节课的关键之一,备课中教师不仅要对教材有很透彻的认识,而且要对自己的学生有全方位的了解,我在准备圆的认识的教学预案时,几经修改,深深体会到在备课中,身为教师应着重解决这几方面的问题:自己作为合作者应该给与学生哪些方面的帮助?作为信息提供者,应该怎样提供信息?以什么方式、什么途径提供信息?下面我就以《圆的认识》谈谈自己的体会。 Preparation lesson is one of the key to a good lesson, lesson preparation teachers not only have a very thorough understanding of the teaching material, but also to their students have a full range of understanding, I am preparing a circular understanding of the teaching plan, after several modifications , I deeply realized that in the lesson preparation, as a teacher should focus on solving these problems: what should be their own partners as co-workers should help? As an information provider, how to provide information? In what ways, what ways Provide information? Now I will “round understanding” to talk about their own experience.
