2014年4月18日,我在苏州市吴江区实验中学参加了苏州市学科带头人课堂教学考核,开设了初二数学《9.1图形的旋转》(苏科版数学八年级下册)。我确立了本节课的教学目标:1.通过实例认识平面图形关于旋转中心的旋转,引导学生用数学的眼光看待生活中的问题。2.经历对生活中旋转图形的观察、分析的过程,探索旋转的基本性质。3.能画
On April 18, 2014, I took part in the classroom teaching assessment of Suzhou city subject leaders at Wujiang Experimental Middle School in Suzhou City, and opened the “9.1 Rotation of Graphics” (Suke Edition Math Grade 8) in the second math. I established the teaching objectives of this lesson: 1. By understanding the rotation of the plane about the rotation of the plane graphic, students are guided to look mathematically into the problems in life. 2. Experience the process of observation and analysis of rotating graphics in life and explore the basic properties of rotation. 3. Can draw
