Imade a deep impression on the Bell teachers in MPI who were so devoted and the courses I involved in. Thanks to the trip to Macau, I actually learned much from the workshops, especially the one whose topic is making teaching in large classes manageable and useful. In my opinion, whether teaching sixteen or sixty students, the teacher needs to be able to organize activities in the classroom, and any activity should be useful for students’ learning. I learned a lot from the courses on how teachers in large classes (40 or more students) can make a range of learning activities more manageable; and how teachers can take more common activities and exercises and adapt them to make sure students learn efficiently from them. We participants in the courses analyzed what makes learning useful, what can help to make a large class manageable, and exchanged a large number of practice suggestions and techniques. All above these benefit me a lot.
