The ALT Conference
The ALT annual conference, altc, is the UK's main conference for learning technologists and one of the largest conferences of its kind. It is held over three days every September, providing a valuable and practical forum for practitioners, researchers, managers and policy-makers from education and industry to solve problems, explore, reflect, influence and learn. More information about altc2013, which was held at the East Midlands Conference Centre, University of Nottingham, is available here.
