教學反思:
It is obvious that any high-productive class needs to be prepared in advance. At present, students may be enthusiastic about participating in class activities, but their linguistic competence will hinder their actual performance. Because of a lack of vocabulary, students often find that it is difficult for them to freely express themselves in English. As for this lesson, they were told to prepare for several activities during class. Apparently, they did quite well in this one. Thus preparation is a key point for a successful lesson. Meanwhile, the teacher should never ignore the importance of daily practice. I have noticed that they were having trouble understanding my English instructions. I think for me, I should pay more attention to daily teaching in order that students won’t have such difficulty in following what I am saying. Besides, the teaching content shall connect to students’ daily life and experiences more closely. So they will always be interested in the class.
