面向一线数学教师的教研活动,采用什么样的形式,最受广大教师的欢迎?最近,我们搞了一次“同课异构”活动,在课本中选定一个课题(灵活度稍大一点的),请几位老师同上这一节课,使用不同的教学设计,采用不同的教学方式.课后,请大家评议、讨论、对比,看哪一种效果好,更吸引学生,吸收效率高;抑或各有千秋,各有所长,各有所短. For front-line mathematics teachers teaching and research activities, what kind of form, the majority of teachers welcome? Recently, we engage in a “class heterogeneous ” activities, select a subject in the textbook (flexibility slightly larger ), I would like to ask a few teachers to follow the same lesson, use different instructional design, and adopt different teaching methods. After class, please comment, discuss and contrast to see which kind of effect is good, more attractive to students and more efficient in absorption ; Or have their own strengths and weaknesses, each have their own strengths, each has its own short.
