摘要:The following article discusses how teacher training deals with digital media from a subject-oriented perspective. Open Educational Resources (OER) have enormous potential to enable effective alternative social and collaborative learning processes during teacher training. We present the initial stages of development of the OERlabs project (funded by BMBF), which aims at operationalizing the potential of OER for biographical learning. Considerations of theoretical concepts are addressed including the potential of OERlabs as a valuable vocational education platform that enables effective collaborative learning, but more importantly addresses the specific individual needs of each learner, especially at the initial stages of teacher training.This paper takes a look behind the curtain of an educational and political hype, while particularly focussing on fundamental pedagogical principles underlying the OER phenomenon.
