I've always liked RPN calculators
I usually use Excel to do long and repetitive calculations. Students aren't used to the notion that they can type up formula only once and keep supplying different numbers to the same formula from say 10 trials. Instead, they just type the formula on calculator say 10 times. They don't understand the difference of algebra and arithmetic so they prefer numbers than formulas.
The spec is not nearly as good as a raspberry pi but has keyboard and color screen. Too bad it runs proprietary OS so not linux and probably not in a million years will it run arduino. So why complain now instead of decades ago?!
If Arduino as a platform (or something else) can help shift content creation partially to students (they have a lot of untapped brain cells), then this may change how teachers teach.
QuoteI've always liked RPN calculatorsMy old HP-67 given to me in college still functions, although the card reader roller turned to mush many years ago. Remarkable device. Rugged. RPN is just the procedure needed to manage technical problems. I once tried a TI my daughter had in high school, entering all those parenthesis wore me out.Ray
I had 5 years of each, all required! That's from 3rd world country.
