Why is this so surprising? Wasn't every teacher a high school student at some point? Is the experience so traumatic that they completely forget what the schedule was like once they become teachers themselves?
Doubt it.
It is rare for teachers to have the time to truly consider the student's perspective in their class, and the context of how that fits into the entire school day experience.
EDIT: I should note that I read this article a few days ago. The entire staff at my school held a discussion on how to make school better in that regard. This blog post alone will at minimum affect the 1400 students at our school, but given the number of places I've seen it shared, it will have a much larger impact than that. Always a good reminder.
I just think it's hard to expect every teacher (even fresh ones, 4-6 years out of high school themselves), to remember these specific causes of what made high school a subpar learning environment.
When I was in high school, I was restless, but I didn't realize it was because I needed some physical activity. I was bored, but I didn't realize that sitting passively for 90% of the day wasn't "normal". I felt like a nuisance, but I didn't realize that I shouldn't.
Every teacher was a high school student at some point, but the memory they formed were not formed with the self-awareness they possess as adults. Re-experiencing the same conditions a decade or two later is enlightening precisely because you understand yourself so much better.
Plus, it seems reasonable that doing the same tasks from the point of view of actually being the teacher, now having a lot more life experience and other things to think about, should make previously normal parts of the experience stand out. If you think this should be unnecessary, and 'obvious' just from thinking back to your own school days, I think you are either highly abnormal or simply wrong.
Is it really that abnormal to remember the stresses of a bad situation, especially when you transitioned to a better one? I can see people not thinking anything is wrong while they are going through the experience, but I really can't find anyone that I know, at least, who thinks high school was a worthwhile experience. And who hasn't had that feeling of relief at the beginning of summer break, and that sick feeling in the pit of their stomach when summer was over? Or recognized immediately on the first day of college that a student actually can be treated like a person, not an inmate?
I recall sitting in a college class that had a recent high school graduate in it, and he raised his hand asking if he could use the washroom. The instructor just looked at him and told him that he is in the real world now, and doesn't need to get permission for a normal bodily function.
Of course, you might be right, in that I probably spend too much time reflecting on something from 25 years ago. It is the main reason that I don't put up with BS from people I work with -- had enough of that from school teachers. But it is possible that it affected me bad enough that I could probably use some counseling about it, if it is considered normal to just forget about what high school (and junior high, to an extent) was like.
In HS I had English, Physics (very fun and active), Drafting (elective), Algebra (1or2), spanish 1. Caring a full backpack was worse for me. I remember it tearing apart on top from the weight
