Answered for language learning in general. No specific language was set for this question, so the findings are drawn from general second-language research rather than one language’s literature.
School language programs tend to underdeliver because classrooms worldwide keep defaulting to teacher-centered, grammar/translation-heavy, exam-driven instruction even when official curricula call for communicative, speaking-focused teaching. This gap is driven less by teachers not "believing" in better methods and more by structural pressures: huge class sizes, rigid packed syllabuses tied to textbooks, high-stakes grammar-based exams, limited teacher training, and misunderstandings about what communicative teaching actually requires.
In many countries (China, Japan, Libya, Morocco, Saudi Arabia, Bangladesh, Malaysia, Kazakhstan), national curricula officially call for 'communicative' teaching focused on real conversation, but classroom observations repeatedly find teachers still relying on teacher-led explanation, grammar-translation, and rote drilling.1,2,3,4,5,6,7,8,9,11,12,13
In plain terms
Because final exams test grammar and reading rather than speaking or real communication, teachers feel pressure to teach 'to the test,' which pushes them toward grammar-focused drilling and away from conversation practice even in supposedly communicative classrooms.8,13,15
Example
Even teachers who say they support communicative, student-centered teaching frequently hold misconceptions about it — for example, believing it means abandoning grammar entirely, that it only works for advanced students, or that it necessarily requires group work — and these misunderstandings shape lesson plans that revert to traditional, teacher-centered activities despite good intentions.9
Learners' motivation, confidence, and willingness to speak up are shaped by the emotional atmosphere of the classroom; approaches that build emotional safety (reducing anxiety, building empathy, and normalizing peer collaboration) are associated with better engagement, while apathy and fear of making mistakes are described as common barriers to progress in traditional grammar-driven classes.4,6,10,16
Example
Specific structured techniques — such as having students take turns acting as 'little teachers' who explain new vocabulary to classmates, timed repeated-speaking tasks (giving a short talk multiple times with shrinking time limits), task-based activities built around real information gaps (planning an itinerary), and structured peer correction of writing — were observed to genuinely increase student engagement and measurable skill gains, in contrast to passive lecture-and-repeat formats.1,15,17,18
