When used episodically PC are applied within a system with other means and training methods; which is why half of a lesson is spent on their application; small oftentimes standard programs are required for that. When used systematically, computers work during many lessons taking the main school hours; special big programs are developed for these classes, where storage techniques are provided (diskette in most cases), presentation of information (mainly on a TV-screen or a display), managing of the learners cognitive work, error analysis and measuring training success of a class in general and every learner in particular.
