Adult ESL isn't the same as teaching kids, and pretending otherwise wastes everyone's time
I've been running adult ESL classes for longer than I care to admit. The ones that actually work are the ones where students leave feeling like they used English to accomplish something real, not like they sat through another gap-fill worksheet about present simple versus present continuous. That doesn't mean worksheets have no place, but they shouldn't be the main course. Information gap activities are probably the single most reliable tool in the room. Student A has a version of a text, schedule, or image that Student B doesn't have, and they have to communicate to fill in the missing pieces. It forces genuine question formation, paraphrasing, and clarification requests because the information gap can't be bridged any other way. I use this constantly. A common version involves two people receiving slightly different train schedules and having to find the connections that work for both of them. Adults immediately understand the stakes because this mirrors actual life situations like coordinating appointments or comparing housing listings. Role plays come next in frequency, but they need to be situationally specific rather than generic. "You are at a restaurant" is too vague for most adult learners. "You need to complain about a delivered order that is completely wrong and you need a replacement before your meeting in an hour" gives the language a purpose and a time pressure that makes the interaction feel authentic. Students absorb functional language faster when there's a concrete objective attached to it.
Problem-solving discussions work well for intermediate and upper-intermediate groups. Present a scenario with multiple constraints and ask students to reach a decision together. Budget planning for a small office move, designing a community garden within a restricted space, or evaluating job candidates for a position. The language emerges from the problem, not the other way around. Students negotiate, justify, disagree, and compromise while practicing target structures naturally. Dictogloss is my go-to for grammar recovery when a class has been struggling with a particular structure without making progress through traditional explanation. You read a short authentic paragraph at normal speed, students take notes on keywords and grammar chunks, then they reconstruct the text in small groups comparing notes and negotiating form. It usually takes about twenty minutes and tends to stick better than three separate lesson slides on the same point.
Why some activities fail with adult learners
The biggest mistake I see is choosing activities designed for children and hoping adults will engage with them anyway. Role playing where students pretend to be animals or act out cartoon scenarios falls flat with professionals who came to class to improve their working communication. Adults need tasks that respect their cognitive level and their time. They'll tolerate fun elements, but the foundation has to feel relevant. Another common pitfall is assuming that more talking time automatically equals better learning. It doesn't. I ran a class once where students spent forty minutes doing a free discussion activity and came out the other side confident they'd practiced English but unable to produce any new linguistic structures. They were operating entirely in their comfort zone. Without scaffolding and a clear language target, open discussion just reinforces existing interlanguage fossilization. Pronunciation work also gets mishandled frequently. Drilling individual sounds in isolation rarely transfers to actual speech. Linking, weak forms, and sentence stress matter far more for intelligibility than perfecting the difference between /v/ and /w/. Students from certain language backgrounds will struggle with those distinctions forever, and that's usually fine as long as they master prosody and rhythm.

A specific problem I ran into and how I fixed it
Several years ago I had a mixed-level group where the B1 students were completing every activity comfortably while the A2 students were silently drowning. I tried standard differentiation by giving the weaker students sentence starters and the stronger students additional questions, but it felt arbitrary and the stronger students got bored within minutes. The class atmosphere suffered across the board. The workaround was task-based layering on a single activity. I used a property rental scenario where all students received the same apartment listing with different tasks layered on top. A2 students answered five direct comprehension questions about the listing. B1 students added three negotiation questions about lease terms. B2 students wrote an email to the landlord requesting specific repairs and negotiating the deposit. The context was shared, the interaction patterns were similar, but the linguistic demands matched each level appropriately. It took about ten extra minutes to prepare materials upfront, but it eliminated the visible performance gap in the room entirely.
Structuring a class that doesn't collapse by week three
Adult learners attend consistently when they perceive tangible progress, so each session should have a clearly identifiable outcome. Start with a brief needs check if the class has been running for a while, then move into a controlled practice segment, followed by a freer communicative task that uses the same language. Close with two minutes of error highlighting where you write three sentences you heard during the activity on the board, two with mistakes and one correct, and have the class identify the issues together. That last step is where the learning consolidates. Homework should be minimal and directly connected to class work. A ten-minute audio recording task where students respond to a prompt using the week's target language is more valuable than a thirty-page workbook chapter. Adults are balancing jobs and families. If you assign work they won't do, you're just creating resentment toward the language itself.
When to pivot your approach
Some methods simply don't work with certain populations, and recognizing that earlier saves months of frustration. Corporate professionals in intensive bootcamp settings need different activities than community college immigrants studying for citizenship tests. The same activity designed for one group will land differently with the other, sometimes dramatically so. I learned this the hard way when I brought a business negotiation role play into a class whose primary goal was navigating healthcare appointments, and half the room checked out because the content felt irrelevant to their immediate survival needs. If an activity isn't producing engagement or measurable language production within the first ten minutes, abandon it and switch to something simpler. A twenty-minute warm-up discussion where students compare weekend plans will sometimes generate more useful language than a designed twenty-minute task that nobody connects with. Read the room honestly rather than defending your lesson plan.
