Phase one of MoLeNET (2007/08) involved 75 colleges and 18 schools, approximately 10,000 learners and 2,000 staff, in 32mobile learning projects. The Learning and Skills Council provided funding for handheld technologies and supporting infrastructure. The LSN MoLeNET Support programme provided advice and guidance; systems and materials; face-to-face, on-line and on-site training and continuing professional development; on-line support including peer-to-peer support and knowledge and resource sharing. LSN research, and LSN supported practitioner-led action research, explored the impact of introducing mobile learning on learner retention and achievement, teaching and learning, learner experiences and participating institutions. The findings of the research are described in this publication.
