All I have is anecdotes but they are troubling. A couple of weeks ago I spoke with a second grader who was brought to tears at the thought of upcoming testing (state required assessment). My immediate thought was something along the lines of "Just do the best you can", but the question remains: where was this anxiety coming from: parents, teachers, both? In this case, education was very clearly trauma for this individual.
Perhaps the "helicopter parents" are doing more harm than good, that seems likely. At the same time, perhaps round after round of assessment testing is hurting as well. And universities seeking to coddle their students, perhaps to keep them "happy customers" but also to keep them ignorant of their overall costs.
In any case, it's not entirely clear that "education is not trauma", this article itself seems to contradict that thesis.
