摘要
在课程改革的背景下,选择了对初中学生而言具有一定难度的教学内容——二次函数图像的平移,并以此为载体探究一位中国经验教师课堂教学策略.发现这位数学教师在教学中采用了＂先整体,后细节＂的教学策略,体现了数学课程改革的教学理念,不过教师对学生认知特征的认识还有待进一步提高。
The study selected a topic of translations of a quadratic function, which is difficult to secondary school students. In order to find out some effective strategies to help student understand this topic, an experienced teacher was chosen in this study. The teacher＇s quadratic function lessons were observed and his lesson plans were collected. The teacher was also interviewed with semi-structured questions after each lesson. This study found that the experienced teacher employed an important strategy which has been advocated by mathematical curriculum standards to facilitate students understanding of translations of a quadratic function, but his understanding of student cognitive process should be improved.
