由特殊到一般，培养数学思维——基于初中数学“勾股定理”教学设计

From Special to Normal, Cultivate Mathematical Thinking—Based on Junior High School Mathematics “Pythagorean Theorem” Teaching Design

摘要: 随着信息化教学的普及，智慧课堂逐渐走向教学第一线，不再是以前靠想象进行刻板教学，可以灵活使用各种软件，GeoGebra动画的使用使得学生更好地理解几何图形的变换，充分做到了教师少言语，而学生自主认知的目的，将课堂充分交给学生，让学生在课堂中主动探索新知。在授课的过程中，通过信息化教学，极大地促进了学生的趣味学习。

Abstract: With the popularization of informatization teaching, the wisdom class has gradually moved towards the front line of teaching. It is no longer a stereotype teaching by imagination. You can use various software flexibly. The use of GeoGebra animation allows students to better understand the transformation of geometric graphics, fully achieving the purpose of teacher’s few words and students’ independent cognition, which will fully hand over the classroom to the students so that students will take the initiative to explore new knowledge in the classroom. In the process of teaching, through information teaching, it has greatly promoted students’ interesting learning.
