Exploring Errors in Target Language* Learning and Use: Practice Meets Theory

The paper tries to answer the question--to what extent the English Language Teaching theory informs the ELT practice in a reflective case study. It argues that even if it is challenging considering what is beyond the theory in practical use of theory, yet if teacher educators in the field of ELT have a solid academic foundation, they will have the responsibility and capacity to challenge the theory, rethink it critically and even revise it.
