从一道选择题引发的教学反思

Teaching Reflections Induced from a Choice Question

教师在教学中是用教材而不是教教材,教材是教师通过教学活动达到教学目标的主要载体,又是学生学习的主要材料。作为教师,首先要钻研教材,深刻地理解教材,能准确、清晰地认识高中全套教材的编写思路和知识体系。只有这样,教师在教学过程中才能根据学生的认知层次,灵活地优化教材这一主要的教学工具,使学生能够完善地构建生物学概念体系,让学生能够在情感、智力、能力等方面得到发展,更好地实现三维目标。

Textbooks are just for reference rather than for teaching, and they are rite study materials tor students as well as the carriers by means of which teachers can reach their teaching objectives through teaching activity. Only after having a good understanding of textbooks, can teachers optimize them flexibly on the basis of students＇ cognition, which conduces to students to perfect the conceptual system of biology, letting students develop themselves well in the realms of intelligence, emotion and capability, a goal being three-dimensional.
