CBI is considered an empowering approach which encourages learners to learn a language by using it as a real means of communication from the first day in class.
There is no single formula for this type of instruction but there are certain models of CBI which are used worldwide to achieve a holistic and global approach to foreign language learning.
Because it falls under the more general rubric of communicative language teaching (CLT), the CBI classroom is learner- rather than teacher-centered (Littlewood, 1981).
Accordingly, students assume active, social roles in the classroom that involve interactive learning, negotiation, information gathering and the co-construction of meaning (Lee and VanPatten, 1995).
Thus, it is important for teachers to give students voice, especially in the current educational climate, which is dominated by standardization and testing (Simmons and Page, 2010).
CBI effectively increases learners' English language proficiency and teaches them the skills necessary for the success in various professions.
With CBI, learners gradually acquire greater control of the English language, enabling them to participate more fully in an increasingly complex academic & social environment.
