The general scheme of human activity's functional structure dealing with psychological analysis of labour and educational activity forms is considered. As a basic one A. N. Leont'ev's scheme is used. Such elements as motive, purpose and condition are distributed on different levels of activity, action and operation. To the basic scheme other structure components: object, means, composure, control, evaluation, product are added, resulting in more completed one. It makes distinct and corresponding levels, stages and substructures of human activity. The most important part (as well as in Leont'ev's scheme) is played by motive and purpose interrelation; their correlation to activity's object is no less important.
