As teachers' perspectives of their roles in teaching activities can greatly inform their pedagogical decision-makings and exert a potential influence on the success of TBLT performance, it is therefore significant for EFL (English as a foreign language) teachers to gain a deep insight of the main principles and their roles of TBLT. This can help teachers truly reap the benefits of TBLT and maximize leaners' learning in a meaningful way.
