Light up sequence scientific calculator buttons

Just like light up piano keys, the scientific calculator buttons light up in sequence to guide the student through the right keypresses

It happened to me! I was able to do the scientific calculator calculations from the book with a few retries, then on the exam I kept getting nonsense from the scientific calculator because I was confused.

While doing the practice problems if the calculator knew what I was doing then the keys lit up in sequence my ability to use the scientific calculator would have gone way up, benefiting exam scores.

So, the calculator glances at the textbook, know which exercise you are doing, then lights up the keys at the correct order. This builds up fluency. Of course some of the exercises could also be done unprompted. There is a piano keyboard that does this, ostensibly to cause learners to more rapidly learn musical keyboarding.

       And, presumably, a calculator that reads the textbook and prompts you to get the right answer would be allowed in exams?   

       The purpose of exams is to sort out the ept from the inept. Your abject failure is what gives the exam system some vestige of credibility, for which you should be congratulated.

       [Max] What's wrong with a student learning in not the most difficult way possible? And how do you get from what [bean] said to cheating on exams?

       Ah, right. Perhaps I misunderhended the idea. Bone rescinded.
