ATIVIDADE ORIENTADORA DE ENSINO: unidade entre ensino e aprendizagem

This article discusses how the concept of activity, understood as the unit of analysis of human development, can support the teacher's work in the organization of teaching, according to the theoretical and methodological assumptions of culturalhistorical psychology. For this purpose, it discusses the appropriation processes of human culture and the role of the collective work in the subject constitution, highlighting the teaching activity as an achievement way of school education. In this sense, the text presents and discusses the potential of the concept of Teaching Guiding Activity which, as it is planned and developed from elements of Activity - need, motive, objectives, actions and operations, enables the development of subjects´ psychism in activity. The quality of mediation in the Teaching Guiding Activity is evidence when it allows the singular subject to take possession of the generic human experience toward theoretical thinking.
