The International Centre for Classroom Research (ICCR) was conceived as a major international facility to support the collection, storage and analysis of data (particularly video data) related to the study of learning and teaching in classrooms. The ICCR houses one of the largest collections of classroom data ever accumulated. Its establishment was a consequence of the need to accommodate data from the Learner's Perspective Study (an international study of well-taught mathematics classrooms, currently being undertaken in 16 countries). The ICCR data set now includes video data from secondary mathematics and science classrooms, primary schools, clinical teaching in hospitals, early childhood settings, and a variety of IT-supported learning environments including tertiary settings. Initially funded with an Australian Research Council Linkage-Infrastructure grant and with the generous support of the University of Melbourne, the ICCR was established at 109 Barry Street, Carlton. The ICCR is affiliated with the Melbourne Graduate School of Education of the University of Melbourne, and the Australian Council for Educational Research (ACER).
