This article first describes the state-of-the-art of model building and empirical research in the field of self-regulated learning (SRL) and then focuses on self-regulated learning in Technology-Enhanced Learning Environments (TELEs). We present recent research results obtained in a European project (TELEPEERS) in the context of which we evaluated TELEs in a peer review manner with respect to their potential for supporting self-regulated learning. In addition, data were obtained on a sample of TELEPEERS students working in these environments and comparative analyses were made across the European project partners.
