This was my reflection in the ESAL course. Today’s class atmosphere and students’ learning enthusiasm were successfully mobilized. Because at the beginning of the class, the teacher first carried out group discussion and practice with classmates. Such activities set at the beginning of the course can effectively help students to bring into the classroom environment, help them quickly into the learning role, but also can mobilize the learning atmosphere. During this time, I could hear the students talking enthusiastically and they were actively learning from each other. While talking about Assignments, the teacher patiently explained the requirements of Assignments. The teacher tried to explain each expectation or requirement in detail and gave examples to the students so that they could fully understand the Assignment requirements and what was expected of them. This method is the easiest and clearest way to explain the relevant content to students. In the process of giving examples, teachers also use different methods, among which the most notable is reverse example, which is to show students negative or wrong cases, so that students can avoid similar mistakes or help them better understand teachers’ requirements. During the teaching period, teachers have been actively asking students what questions or ideas they have about the course. Seeking immediate feedback from students is beneficial for both students and teachers. Teachers can immediately know the feedback of their own teaching, and make corresponding adjustments or changes according to the feedback, which is helpful to help students further and better understand the course. It’s also a good opportunity for students to learn something they don’t know or understand. Overall, this class has always used the student-centered teaching method, and the class efficiency is very high.
