Read the【Case Reflection】in this section and think about the questions:

Research conducted by American scholar Stevens found that most questions put forward in class by elementary and middle school teachers in the USA were closed questions. The teachers were not good at designing thought-provoking questions. The ineffectiveness of questions put forward in class was further confirmed in another survey done by British and American scholars: 3 out of 5 questions required memorizing language points, 1 out of 5 was used to monitor the class, only 1 out of 5 aimed to stimulate students to think. However, according to Stevens, “Effective class questioning” is the core of successful and effective teaching in class, which means that if we want to improve our teaching, we have to improve the effectiveness of the questions put forward in class (Guang Ming Daily 2009/3/19) .

What do you think of the report mentioned above? Have you ever noticed what kinds of questions your teachers usually ask in class?
