SOLO Taxonomy

Introduction

The SOLO Taxonomy (Structured of Observed Learning Outcome) is a way of assessing the complexity of understanding achieved by a student with respect to a particular learning outcome.

This taxonomy was proposed by John B. Biggs and K. Collis. A similar way of approaching the complexity of student learning is Bloom’s taxonomy.

The SOLO Taxonomy

There are five levels of complexity that can be identified in the way that a student understands or has responded to a learning outcome and the associated learning activity. These reflect increasing competence and higher order thinking and learning.

  • 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.
