1、课堂提问频率差异新教师在整个课堂40分钟内共提出60.5个问题,平均每分钟1.51个问题;专家老师平均共约提出40.5个问题,平均每分钟1.01个问题(表1)。可见,问题的数量不能太多,密度不能太大,否则反而会造成教师越问学生越糊涂的现象。问题的设计应激起思考,而思考需要时间,提问速度不能太快,留给学生回答的时间不能太短,让学生有充分思考的时间,教师应放慢提问的速度,教学气氛应
1. Frequency Differences in Classroom Questions The new teachers proposed a total of 60.5 questions within 40 minutes of the entire class, with an average of 1.51 questions per minute. On average, the experts and teachers made about 40.5 questions, with an average of 1.01 questions per minute (Table 1). Can be seen, the number of questions can not be too much, the density can not be too large, otherwise it will result in teachers more students more confused phenomenon. The design of the problem should be stimulated, and the thinking takes time. The speed of the questioning can not be too fast. The time left for students to answer should not be too short. Students should have sufficient time to think. Teachers should slow down the pace of questioning.
