Some lessons don’t just get a little off-track; they fall apart before your eyes. The explanation is muddled, the activity is poor, the answers are missing, and the lesson falls apart before it even starts. To a novice, a lesson like that can feel crushing, because it’s all too easy to confuse a bad lesson with evidence that you’re not a good teacher. A simpler, better perspective: A bad lesson is not the end of the world. It’s raw data. It tells you where the design was flawed, where the example was opaque, where the task overreached. Bad lessons improve us the fastest when a bad lesson is studied, not dismissed.
When you have a bad lesson, resist the urge to just scrap the whole thing from scratch. You can do that. You probably feel like you have to. Start over. Watch the whole thing again, and try to pinpoint exactly where your learner’s understanding broke. Was the lesson goal too vague? Was the explanation given in a way that was unconnected to an example? Did the practice task appear before the instruction had stuck? Those are more concrete questions than “was the lesson good?” If the learner could parrot what you said but not do the work, then maybe the lesson lacked transfer. If the learner stopped answering during the explanation, then maybe the learner had an information overload. You begin recovering when you identify one concrete problem to solve, instead of “fixing the whole thing,” because you’re sure “the whole lesson was bad.”
One common mistake in fixing bad lessons is to add more content to the next lesson. The idea sounds logical: If they didn’t get it, then I need more explanation. Usually, the result is more confusion. Fixing bad lessons is usually about subtracting content. Reduce the lesson objective, reduce the example, and reduce the practice task to one discrete skill. If a lesson on paragraph writing was bad because it mixed topic sentences, supporting sentences, and transitions in one lesson, then teach the topic sentence, and ask the learner to identify a good topic sentence. If the grammar lesson was so bad because there were too many rule exceptions, teach the basic rule in three sentences. You get better by focusing, not adding content.
A fifteen-minute lesson recovery routine can change a bad lesson into practice for the next one. Take three minutes to state the original objective in one sentence and then trim it down until only one objective remains. Use four minutes to decide on a simpler example and to rehearse the explanation in one minute or less. Take another four minutes to design one practice task that tests the learning objective without adding extra content. Finally, spend the last four minutes predicting the most likely misunderstanding for this specific lesson and planning one minute of re-instruction. This kind of lesson recovery works because your focus is on the design of the lesson, not on yourself. Soon, you’ll be able to tell when and how to shorten a lesson.
When you feel stuck and are having trouble figuring out what was wrong, look at the last meaningful response the learner gave before the confusion. Often, it tells you more about the state of the lesson than any other source. Maybe the learner did the example correctly, but not the independent task correctly. Maybe the learner answered correctly, but could not apply the knowledge in another form. These tell you whether the next time requires better examples, better sequencing, or a better check for understanding. And if you can, rehearse your new explanation out loud before teaching the revised lesson again. You find out how your explanations sound when read out loud, and how your explanations change when you try to speak them as opposed to writing them.
The key to being a better teacher is not that your lessons go right. The key to being a better teacher is that the lessons that go wrong are turned into better lessons through attention and practice. Every time you teach a lesson, it’s a step closer to understanding how long, how clear, and how simple it needs to be. Not to avoid failure. Instead, to know what failure tells us. To build a new lesson, step by step. To be faster, sharper, and easier to understand than the last one.
