Thesis work is challenging to both students and supervisors. The traditional model of supervision is that one supervisor individually supervises thesis work. In higher education this model has been challenged with new approaches such as blended group supervision to make the process more interactive and to provide support for students to complete the thesis work on time. In this paper we report from an effort to design a model for blended group supervision with the aim to provide structure and support for students as well as supervisors. The model is discussed in relation to the theoretical concepts zone of proximal development and scaffolding.
