The element of resistance is talking about when you are unable to do something because there is something stopping you. For example, if you are playing football and you are trying to score there is going to be resistance from the opposing team. You are not going to be able to just walk down the field. That is the same way in this case when Gee is talking about it. When Gee is talking about metaknowledge he is talking about when someone knows so much about what they are doing that they usually become the best at it. If someone was trying to be a doctor they have to get taught by the people who have metaknowledge which would be the residents in the hospital.
