What CLT got right
Communication drives acquisition, not just demonstrates it. The foundational insight of CLT - that students learn language by using it, not just by studying it - remains one of the most robustly supported ideas in second language acquisition research. Swain's Output Hypothesis, Long's Interaction Hypothesis, and decades of classroom research all point to the same conclusion: speaking is an acquisition driver, not just an acquisition outcome.
The affective filter is real. Krashen's concept - that anxiety blocks language processing - is not just intuitively true, it's neurologically documented. Students who feel safe produce more language. Students who feel watched and judged produce less. Any teaching method that lowers anxiety produces more learning, and CLT's emphasis on meaning over form tends to do exactly this.
Authentic purpose matters. Students who are communicating for genuine reasons - to solve a problem, to persuade, to share information the other person actually needs - produce more complex and more accurate language than students performing exercises. The information gap research is clear on this. See our post on
information gap activities for practical applications.
Pair work is the most efficient format for speaking practice. This is now supported by enough research to be considered established rather than contested. In a class of 30, pair work multiplies individual speaking time by approximately 14 compared to teacher-led Q&A. The mathematics are simply compelling.
Where CLT overclaims or gets complicated
"Authentic communication" in classrooms is largely fictional. Students know they are in a classroom practising a language for assessment purposes. The communicative scenarios they engage in are, at best, simulated authenticity. This doesn't make them worthless - simulated authenticity is a perfectly valid pedagogical device - but the stronger claims about CLT producing "real" communication in classrooms need tempering.
Accuracy is not the enemy of fluency. Early versions of CLT were almost anti-grammar: the focus on meaning was so dominant that explicit grammar instruction was considered counterproductive. The research does not support this. Spada and Tomita's meta-analysis found that explicit grammar instruction alongside communicative practice produces significantly better outcomes than either alone. Modern CLT should embrace this.
CLT is not a method - it's a set of principles. This is both its strength and its weakness. The principles (meaningful tasks, learner-centredness, communication as the goal) are robust. The absence of specific methodology means that "we use CLT" can describe anything from genuine task-based teaching to a grammar lesson with one communicative warm-up. The label obscures more than it clarifies.
Not all learners benefit equally. CLT tends to work better for learners who are already comfortable in social situations, who have some baseline language, and who are in contexts where English has communicative relevance. It works less well for anxious learners, beginners with no productive vocabulary, and learners in contexts where English is purely academic. Context-sensitivity is the gap in most CLT accounts.
Tool tip: YapYapGo implements CLT's core principles in a practical format: genuine communicative tasks (pair discussion with real information exchange), minimal teacher intervention during speaking, structured modes that scaffold without scripting. A conversation topic generator provides the communicative prompts; you provide the context and the feedback.
