I don't agree in placing the blame on teachers. There will be exceptional teachers, as there are exceptional people in any field, but those that are exceptional rise above the boundaries and restraints of the curriculum.+Steve Kappes
I think what people are concerned about with this kind of question, is that it is irrelevant. You are right, there was no intention behind teaching someone to use a microscope - that is the problem.
It doesn't matter what you do or who you talk to, content is nothing without context. Asking the star athlete of the class to read about a microscope might fall on deaf ears (I'm totally generalizing). Ask him to read an article about which person jumped the highest or ran the fastest and you are sure to hit a nerve - literally.
Everyone knows this, but it is exhausting for a teacher to do. Rewrite the same curriculum for every kid? Come on!!
But kids neural pathways lighting up like firecrackers when you hit a subject they are interested in isn't a problem - it's an opportunity. The teacher isn't the problem, because if all teachers were exceptional - it would defeat the definition of exceptional.
The curriculum is the problem, and therein lies the opportunity.
