If it were up to me, a student would have a textbook, pens and paper, and math or science charts only.”

Like we used to have back one could learn something in public school. Although later some students required a slide rule or an abacus.

There is no better way to learn. I think the only way one could improve upon that is through virtual reality where a student could interact with a teacher repeatedly until the subject material was mastered.

I think any math student towards the end of each course (and having a thorough grounding in the basics)should begin
using a graphing calculator. High school students without that skill set will be at a disadvantage in college level courses.

Another alternative-for juniors or seniors only; a separate 15 week course on using a graphing calculator.

I would allow students to use slide rules. One has to know what one is doing to use a slide rule. Textbook, paper, pencils, eraser, charts, slide rule. That is all they need.
