Nowadays, foreign language skills are very important for working in multicultural and multi-language environments. Communicative Language Teaching (CLT) is considered as an effective method to learn a language. In Vietnam, CLT is not strange, but how frequently it is used in EFL classroom is still a question. A survey on students’ opinions about frequency of using Communicative Language Teaching (CLT) activities in their General English (GE) classes was conducted at Can Tho University in semester 2, academic year 2015 - 2016. The study aims to find out how frequently lecturers use CLT activities in their classrooms. Both quantitative and qualitative data were collected via a questionnaire for students who participated in General English course in previous semesters, and were analyzed on SPSS version 20. The study found that (1) CLT was sometimes used in GE classes, and (2) General English teachers sometimes (not often) use English in class. However, more than 90% of the participants reported that they improved their English after the General English courses. The learner’s expectation about a favorite way to learn English was also collected. The study gives some pedagogical implications and suggestions.
