Short answer
Decide what matters most for the task, notice repeated patterns and allow learners to finish important stretches of communication. Correction is more useful when it is selective enough for the learner to process and reuse.
In S06E15, Em gives a long example about her company while Gav corrects nearly everything. The result is deliberately exhausting. The message disappears under a pile of corrections.

That scene exaggerates something that can happen in real lessons. A teacher hears an article problem, a tense choice, an awkward collocation, a pronunciation issue and a missing plural within twenty seconds. Every item may be technically worth discussing, but the learner cannot work on all of them at once.
Start with the purpose of the activity. In a fluency task, let the learner build the message and collect a few useful errors for delayed feedback. In controlled practice of a target structure, correct more closely because accuracy is the point of the task.
Repeated errors deserve more attention than isolated slips. If the learner repeatedly drops be, confuses past and present or misses plural endings, that pattern can become a clear teaching focus. A single strange phrase in an otherwise successful story may not need to interrupt the moment.
It also helps to acknowledge successful communication before correction. Show the learner that you heard the idea, not just the mistake. Then choose one or two points that will make the biggest difference.
The goal is not fewer corrections because correction is bad. The goal is better-timed correction that the learner can actually use.
Which errors should come first?
Prioritise errors that block meaning, repeat frequently, connect directly to the lesson aim or are realistically within the learner’s reach. Defer lower-priority issues and come back to them when they can receive proper attention.
Our suggested classroom adaptation of the episode discussion.
Gav and Em suggest: The correction priority check
- ☐ Did the error block the meaning?
- ☐ Is it connected to today’s target language?
- ☐ Has the learner made it several times?
- ☐ Can I explain it clearly in a short space?
- ☐ Will interrupting now damage the learner’s fluency?
- ☐ Can the learner realistically use the correction straight away?
You do not have to fix the whole learner in one lesson. Pick the correction that helps the next sentence.
