Hi Jenny, Deirdre,
In my view the Emergent Learning Artefact (I did mention this Artefact somewhere else in this forum) is a proof or evidence of this emergent learning of this student. You (Jenny) are right I think, the Emergent Learning Artefact does fit into the bonus area of the rubric of Deirdre Bonneycastle.
Great idea of Deirdre to make a special room for the unexpected. If we do not expect that some unexpected thing could be happening, we will not notice it.
