In order to better carry out the undergraduate quality teaching of foreign students, the Internationalization Department of the School of Computer Science organized a trial teaching activity for new teachers. Teachers Shi Leilei and Liu Min were the teachers of the English courses Machine Learning and Introduction to Computer respectively. They held a 20 minute lecture and introduced the K-MEANS algorithm and the conversion of computer system. Each teacher was well prepared, fluent in English, and the classroom effect was good. Finally, the supervisors, Professor Ju Shiguang and Professor Zhan Yongzhao, made comments and suggestions on the teaching methods of the two teachers. Zheng Wenyi, Zeng Lanling and Zeng Yu from the Internationalization Department also participated in the exchange.
