2007年7月,我参加了福建省2007年普通高中新课程骨干教师省级研修班高二数学班的培训,这对于磕磕碰碰地实践了一年的新课程,疑惑不断,思考不断,问题也不少的新课标教材的使用者们来说应该是一个指点迷津、补充营养的文化大餐·其间,《正弦定理》的公开课,整节课,学生答题踊跃, In July 2007, I took part in the training of the Gao Er mathematics class for the provincial training course for senior teachers in the general high school new curriculum in Fujian province in 2007. This practice has taken a year’s worth of new courses. I am constantly puzzled and thinking, and I have problems. Many users of the new course materials should be a cultural meal that is full of attention and nutrition. During this period, the open class of “The Sine Theorem” is full of classes and the students’ answers are enthusiastic.
