课堂教学组织不当、提问后等待时间不足、评价学生的方法欠妥、不擅于赏识激励学生、难度把握不当、驾驭教材能力差、随意打断学生的讲解、不擅于稚化自己的思维、不擅于暴露思维过程、放羊式或一言堂等“教师不会教”是致教学低效的重要因素,值得研究和重视. Inadequate classroom teaching, lack of waiting time after questioning, inadequate method of appraising students, lack of appreciation of students, difficulty in mishandling, poor ability to control teaching materials, arbitrarily interrupting students’ explanations, and not being good at accelerating their thinking Not being good at exposing the thinking process, ramming sheep, or saying things like “teachers won’t teach” is an important factor in inefficient teaching. It is worth studying and paying attention to.
