建构式生态课堂中,教师的主要责任是点拨和引导。帮助学生学会思考;引领学生学会探寻、使用有效的信息;设计灵活多样的学习活动,让学生自主探究、合作展示,形成良好的学习习惯和学习方法。然而在实际教学中,我们会发现,学生学习的主动性和积极性并不高,对交流和展示也没有太大兴趣,并没有达到我们教师预想的效果。反思其中原因,做好课前的预习工作,让学生自主学习,可以为交流的展示做好准备,增强学生自信,提高课堂效率。 Constructive ecological classroom, the main responsibility of teachers is to point and guide. To help students learn to think; to lead students to learn to explore and use effective information; design flexible and diverse learning activities for students to explore, co-display, the formation of good learning habits and learning methods. However, in the actual teaching, we will find that students are not very active and motivated to learn, they are not much interested in communication and exhibition, and have not achieved the effect that our teachers expected. Reflect on the reasons, do a good job in pre-class work, so that students can learn independently, can prepare for the exchange of the show, enhance student self-confidence and improve classroom efficiency.
