Recently, a shift towards more communicative and eclectic methods and approaches of foreign language teaching in Vietnam has led to a change in classroom time for students to actively communicate with one another. As students expect to find learning speaking challenging, it is required that EFL teachers find out innovative ways of teaching speaking skills. Moreover, Ur (2006) claimed that of the four language skills (listening, speaking, reading, and writing), speaking seems to be the most important, but challenging. Speaking is an interactive process of constructing meaning that involves producing, receiving and processing information (Burns & Joyce, 1997). Students need to develop different skills and strategies to keep conversations going on. It is required that they not only know how to produce specific points of language such as grammar, pronunciation, or vocabulary, but they also understand when, why, what and how to talk. In addition, it is also a commonly recognized fact that achieving proficiency in foreign language speaking in classroom conditions is not an easy task. This difficulty is basically due to the students and inadequate frequency of speaking opportunities in the classroom in comparison to the abundance of natural varieties and genres of oral communication (Nation, & Newton, 2009). Nonetheless, the skill of speaking is not automatically transferable from the speaker's first language into the target language (Thornbury, 2007). In cases where there is little chance for oral interaction outside the classroom, it is thus imperative to optimize the classroom time available and create opportunities for the development of students" speaking skills. One of the best ways is using a procedure based on the use of speaking tasks as the core unit of planning and instruction in language teaching to enhance EFL students" speaking ability (Richards & Rodgers, 2001). TBLT has been considered to create a real purpose for language use and provide a natural context for language education through the use of different tasks (Willis, 1996). TBLT is a language teaching and learning approach which has been used since 1980s. It is accepted by linguists and foreign language teachers, researchers and curriculum developers for last three decades (Breen, 1987). That is because a language is best learned through using it (Thornbury, 2007). Lee (2000) defines "a task as a Abstract: Task-based language teaching (TBLT), a language teaching and learning approach, has been received much concern from language educators and researchers in different contexts for the last three decades. With a desire for making a valuable addition to the literature, this study, therefore, aims to explore how EFL teachers at a private university in Ho Chi Minh City-Vietnam (henceforth called PUH) perceive TBLT principles and discover what EFL teachers' and students' perceptions of the types and advantages of task-based speaking activities (TBSA) used in EFL classes at tertiary level. The study involved 383 students and 10 EFL teachers. Both quantitat...
