The rhizomatic model of learning is an approach to curriculum design that is not driven by predefined inputs from experts; it is constructed and negotiated in real time by the contributions of those engaged in the learning process. This community acts as the curriculum, spontaneously shaping, constructing, and reconstructing itself and the subject of its learning in the same way that the rhizome responds to changing environmental conditions.
Dave Cormier has written an excellent paper (IMHO) that explains rhizomatic education in greater detail.
Prof. David Nicol has researched assessment at HE level over a number of years culminating in the publication of the REAP project. The key assumption of the REAP project is that if we wish to enable students to develop as self-regulating learners they must be given a more active role in assessment processes.
Can you see a link between Nicol's research and the rhizomatic model of learning?
