Hierarchical Microcontext Technology and Graph Environment PYTHAGORAS

摘要

The research is devoted to micro-context approach to computer technology education, and to engineering of languages and software. The main idea for education is: to study at first not big multiparadigm language (such as Pascal or Logo), but the set of orthogonal micro languages. Then to decompose any development task into micro contexts, each of them can best be supported with its specific micro sub language, and to input and to interpret such multilevel specification in composite media. This one has to include set of independent components; each serves specific kind of work with specific primitive microlanguage (editing, compiling, interpreting, etc.). More, we propose always preparing big language when study to hierarchy of micro sub languages. The approach is assisted by the PYTHAGORAS media. Characteristic features of the PYTHAGORAS are microlanguage technology support, and inclination to "game style" of work.
