SOLO Taxonomy SOLO Taxonomy (structure of observed learning outcomes) provides a simple, reliable and robust model for three levels of understanding – surface deep and conceptual (Biggs and Collis 1982).
Pre-structural - The task is not attacked appropriately; the student hasn’t really understood the point and uses too simple a way of going about it.Uni-structural - The student's response only focuses on one relevant aspect.Multi-structural - The student's response focuses on several relevant aspects but they are treated independently and additively. Assessment of this level is primarily quantitative.Relational - The different aspects have become integrated into a coherent whole. This level is what is normally meant by an adequate understanding of some topic.Extended abstract - The previous integrated whole may be conceptualised at a higher level of abstraction and generalised to a new topic or area.
