First of all, you should adjust your mentality, and don't feel how important the foreign teacher class is and give yourself too much psychological pressure. Think of it as daily oral communication. At the same time, it will be helpful for your study to get ready before class, adapt yourself to a completely English communication environment, and even treat yourself as an Englishman.
Secondly, you should have an intuitive understanding of the course, know the theme of the course, and do some preview in advance. Many foreign teachers don't have any syllabus, only a general scope. You need to look up the information yourself, and be prepared in advance for the questions you don't know and what you want to express.
Don't get stage fright in foreign teachers' class again. Foreign teaching classes are often not for listening, but for speaking. If you want to improve your spoken English, you should keep trying to communicate with foreign teachers. Even if you can't speak well or can only use some simple words, you should be brave enough to express yourself.
In fact, the teaching level of foreign teachers is not much better than that of domestic teachers, and even worse in many aspects. They are not used to the teaching methods in China, and many foreigners who come to China to engage in the education industry don't know much about education themselves. Now they are in a state of learning and selling. If you just attend classes, Mr. China's advantage is more obvious. The main function of foreign teachers is to correct your oral pronunciation and make you adapt to face-to-face communication with foreigners.
In addition to the above things to prepare, you can also bring a recording pen to record your expressions in class with foreign teachers. You can play it back slowly after you go back and listen to it repeatedly to adapt to this context, which will be of great help to improve your English. And listening to your own foreign language expression will make you more deeply aware of your own shortcomings, and you can make targeted improvements in the future.
Finally, all you have to do is summarize. Generally speaking, teaching a foreign language won't last long, and most students don't have so many opportunities to contact foreign teachers often, so you should learn more in a limited time. After learning, you must record what you have learned in this class, practice more, form a deep impression in your mind, organize what you don't understand into a document, and take it out and ask it carefully in the next foreign teacher class.
