The SOLO taxonomy (Structure of the Observed Learning Outcome)

The SOLO taxonomy (Structure of the Observed Learning Outcome), which is based on the study of outcomes in a variety of academic content areas, was used to classify the student learning outcomes for the student work gathered, as well as outcomes and activities observed during the classroom observation. “As students learn, the outcomes of their learning display similar stages of increasing structural complexity. There are two main changes: quantitative, as the amount of detail in the student's response increases, and qualitative, as the amount of detail becomes integrated into a structural pattern” (Biggs, 2003). The SOLO taxonomy thus provides a means of evaluating at which level instructors and students were operating.
