In addition to traditional methods, effective but less used methods were also introduced, such as: learner-centered, discussion, interactive and content-focused. In particular, lecturers also had the opportunity to try out new ways of preparing lectures and creating curriculum frameworks, learning from leading professors in the field of teaching Vietnamese as a foreign language. MSc. Nguyen Phuong Chung is also working with colleagues to prepare a new book, focusing on students, focusing 100% on what students need in real life. The lectures are done according to the backward design model. This is a lecture preparation technique that has been applied in many places around the world, but is still quite new in Vietnam. The book is expected to be released next September.
