The Group for Research on Interaction and Educational Influence (GRINTIE) belongs to the Department of Developmental and Educational Psychology at the University of Barcelona (Spain). Since the beginning of its activities, at the end of the eighties, the Group is directed by Dr. César Coll. Since 1995, GRINTIE is part of the Group "Development, interaction and communication in educational contexts". The quality of the research activities of this Group has been recognized by the Department of Universities, Research and Information Society of the Generalitat de Catalunya.

The aim of GRINTIE's work is the study of "educational influence processes". We use this name to refer to the processes, essentially interpsychological, by which educators (professors, parents...) help learners (students, children...) to construct knowledge in educational situations. This study is approached from a constructivist and socio-cultural perspective. From this point of view, GRINTIE has treated subjects as the analysis of teacher/student and adult/child interaction, the analysis of educational discourse, and the assessment of learning in the classroom. The group has also developed intervention projects related with learning communities and educating cities.

GRINTIE's work, at present, is focused in the study of the relationship between interaction and knowledge construction in computer-supported teaching / learning processes.
