you can learn from your mistakes and corrections. Keep on going.
For several years, I devoted two whole 1-hour lessons (and five minutes of the previous one) teaching my Y9 class something that was completely untrue. None of them questioned the false information. They then drew graphs, practised their interpolation and extrapolation skills, made predictions, planned and carried out an experiment to test their hypothesis.
When their results were nothing like their predictions, I challenged them to explain. Even then, most were unwilling to accept what was staring them in the face and thought they must have done something wrong.
But there was always one girl (fortunately, because I was relying on this) who would tentatively raise her hand and question the validity of the original data.
I heaped praise on her (partly in the hope of encouraging anyone else who might have been thinking along the same lines but was too shy to say so) and came clean. They were astonished that a teacher would do that to them.
But then I pointed out that a whole class of intelligent people had believed something which was blatantly untrue (I then demonstrated how it ought to have been obvious) and that if they hadn't done the experiment, and actually thought about it, they might have continued to believe, indefinitely.
(See my post upthread regarding the effectiveness of lecturing as a teaching method.)
So yeah. Thinking.
