A proposal of programming education system using mechanical calculator mechanism

Today, programing environment is too complexity to learn for programing beginners. Programing tools witch are languages, libraries, software and methods are improved. However, it causes to demand high functionality and multiple functions. Beginners are taught many commands and techniques, before they get good goal for learning. For the reason, they are bad at constructing algorithms. Our paper is focus on this problem. We entertain comprehensible algorithms. We try to use mechanism of old calculators. After then, we propose a new system witch are based on Tiger calculators, witch are the most popular mechanical calculator of Odhner arithmometer type in Japan.
