So instead of "everyone needs to learn to accept correction gracefully," you risk teaching them "regular/stupid people need to learn to accept correction from smart people."
There's a corollary: "Smart people need to learn to give feedback in a way that doesn't annoy stupid people but let stupid people accept their feedback." You probably would have profit from learning that skill in third grade.
I did learn that skill much earlier than I learned to accept correction gracefully from others. I had much more occasion to practice tailoring my feedback to others so that it would be accepted than I had to practice receiving and incorporating it.
I don't think smart students are as shortchanged when it comes to learning that skill as the reverse, with the current status quo.
As a teacher, I wonder if it is possible to instill this skill into students the skills of rationality and critical thinking. I teach the third grade, and it is not immediately apparent how to apply this with my own class.
The problems I foresee are as follows:
In the sequences, it is suggested teachers should drill into students words don't count, only anticipation-controllers. How practical is this for an elementary school level? Also appreciated would be any ideas or experiences on how to do this, or how to combat the above problems. Hearing from other teachers would be excellent especially.
