This was my second reflection in the ESAL course. The main content of this lesson is about countable nouns and non-countable nouns. Before the class began, I noticed that the teacher asked the students a question, which impressed me deeply. The teacher asked the students if they had any questions before we began. I think this is a very good way, and also provides a good opportunity for students to review the knowledge of the last class, and encourage students to ask questions, and finally achieve the purpose of learning. For the main content of this lesson, the teacher used the most method is to give students examples. This method is the easiest and clearest way to explain the relevant content to students. There is a Chinese idiom called “drawing inferences from one case”, which specifically means that one can infer or draw other cases from one case, which means that learning can be put into practice. In this class, I saw that the students really achieved the purpose of drawing inferences by analogy under the teacher’s encouragement and help. In the process of teaching, teachers also help students to understand and learn nouns by combining textbooks and multimedia systems. Audio playback helps improve students’ listening ability and spelling ability. When the students do not understand the content and the textbook, the teacher also responds positively and patiently explains. This not only reflects teachers’ respect and attention to students, but also helps teachers have a clear understanding of the progress of the class, so that teachers can timely adjust the teaching methods and progress. In the middle of the course, some students were inattentive. At this time, the teacher used group discussion and random questions to help students concentrate and improve their participation in the class, which was an effective method. At the same time, it is very important for teachers to constantly review what they have learned, which is also frequently reflected in this class. After the break, the teacher led students to review the content of the first half of the class, which not only helped students review what they had learned, but also helped them return to the state of class in time.
