The stage of the 21st century education technologies is specified by the technology development level, dependence of economics on information technologies and computer network progress. Technical and educational training aids have a pronounced influence on the training activity.

Currently educators are active in defining what 21st century competencies are and how they can be efficiently integrated into existing educational systems. Informatics education was begun at schools of many countries almost 50 years ago, but with the onset of this millennium it slackened due to the need for use of technologies in practice.
