As the basis we use the idea of a culture of participation to analyse existing systems and suggest enhancements for them. Our aim is to help improve the active engagement and collaboration of learners with the learning material and with fellow students. First, we conduct a literature review of collaboration and participation in e-learning. Afterwards, we analyse an existing tele-teaching web portal for the implementation of the culture of participation. Design principles and requirements extracted during literature review are used for the analysis. Finally we suggest different improvements to really create a culture of participation in tele-teaching. As an example feature we use collaborative digital video annotation.enText/Conference Paper1617-5468
