KuMir (Set of Educational WORLDS) is a programming system designed to support initial computer science and programming courses in secondary and high schools.
Peculiarities:
✔ The KuMir system uses a school algorithmic language with Russian vocabulary and built-in executors Robot and Draftsman;
✔ When entering a program, KuMir carries out constant full control of its correctness, reporting in the fields of the program about all detected errors;
✔ When executing a program in step-by-step mode, KuMir displays the results of assignment operations and the values of logical expressions in the fields. This allows you to speed up the process of mastering the basics of programming.
