one aspect of educating we auties we do love routine to plan our days difficult in a classroom situation and where some students grasp information far quicker What has enabled autie students to settle into a classroom . By utilising by the teacher and teacher being aware of the child when in a stressful or to calm themselves .will revert back to their base calming routine and lining up dolls or hiding in a dark room or music or stimming The trick to get the student accepted is too identify the act and utilise that in a class or if the student loves cars trucks and can use that in maths or comprehension . This has been a very successful way of getting the autistic child involved less likely to be gaslit or isolated and bullied. mi e was a love of plants geography and world war battle stats

I understand the question a bit differently, but here is my way with routine but not sameness. I enjoy stretching my brain around new things, I always have. I did well in an environment where routine was king, we started at the same time each day, we broke for lunch at the same time every day, we finished at the same time each day, etc. I also excelled at learning and if there was sameness, such as repeating the same lesson, or a segment of curriculum moving to slowly, I would end up floundering around mentally because I would consume every bit of information that was available on a topic, then I needed to move forward to the next topic, or build on the current one. Put simply I had to be in my chair at 8:00 am every day, but I needed different and new information each day.

@lisalucier Here is my take on it. Sameness means eating a meal or two meals everyday at the same time, and each of those meals in its own right is the same every day. Routine on the other hand, may be eating a meal at the same time each day, but the contents of those meals are different on a daily basis. A good example of routine growing up in my household was Monday and Wednesday breakfast was bacon and eggs. Tuesday was French toast. Thursday was waffles. Friday was eggs and toast. Saturday was cold cereal until we were old enough to make our own oatmeal. Sunday was usually pancakes made by my dad. Breakfast was the same time every day. Six days a week, dinner was at 6pm. Now as everyone left the family home, the times changed a little bit but not by very much. Even until he was put into a Skilled Nursing Facility, my dad kept a very timely routine for his meals.

Now as to my schooling, routine was not so much the issue as the sameness. Like @auntieoakley, I absorbed information quickly and was always looking for more. This left me a very bored student because I was ahead of everyone. I made all efforts to keep myself occupied. I started writing. Mostly poetry and commentary, and I still have it all! In high school I had one teacher who saw what others didn't, and kept me challenged mentally. I was two years ahead of my same grade in technical studies, but I was not allowed to jump grades. That's another subject for another day.

I will be getting into reading that article that @mamacita has referenced.
