#### Description

These MathsCasts are produced by the mathematics support centres at Swinburne University, the University of Limerick and Loughborough University. They are part of an ongoing collaborative research project to develop high quality resources and investigate the effectiveness of MathsCasts to support mathematics learning. They are mostly targeted at prerequisite to first year level, in a range of subjects such as: Engineering, Sciences, Business, Computing and Technology. We have also commenced production of second year mathematics topics.
