The paper draws on the theory of learning by Knut Illeris to interpret data from qualitative research in intergenerational learning at Czech primary and lower secondary schools. It is focused on describing the forms of interaction through which intergenerational learning among teachers takes place, i.e., perception, transmission, experience, imitation, and participation. The results of the analysis are interpreted in the school context in order to show how interaction research may contribute to the analysis of intergenerational learning in a specific institution.
