SOLO taxonomy

SOLO Taxonomy describes the developmental progression of learning through five levels of understanding: Pre-structural, Uni-structural, Multi-structural, Relational and Extended-abstract. Its structure, along with verbs associated with each level of the taxonomy, guide learning design that supports student mastery and metacognition.
Initially developed by
John B. Biggs (University of Newcastle) & Kevin F. Collis (University of Tasmania), Australia (1982).
Effectiveness
John Hattie's Visible Learning for Teachers: Maximising Impact on Learning (2012) describes SOLO Taxonomy as "the most powerful model" for understanding students' learning.

Where you'll find it in Stile
Every question in Stile uses a verb that connects with the levels of understanding in SOLO. Within a lesson, questions build understanding through the SOLO progression. Units culminate in assessments that allow students to demonstrate extended-abstract thinking.
Examples within Stile

Socratic seminar

Students apply their cumulative knowledge of energy conservation to research, discuss and make recommendations regarding the proposed Congo dam.
Socratic seminar: The Congo dam project lesson
in the Energy Conservation unit
Text: Discuss whether the Congo dam should go ahead in a Socratic seminar. Image: Illustration of diverse participants including a local villager, resident of South Africa, scientist, and engineer discussing around a seminar circle diagram.

Engineering challenge

Students use their understanding of ecosystems and a global declining bee population to engineer a solution over a series of lessons.
Defining the problem lesson
in the Importance of Biodiversity unit
Text: Engineering challenge. The problem that needs solving is… My goal is to solve this problem by… Image: Illustration of students and scientists working with blueprints, robotics, and a laptop, with bees shown in the bottom left.

Critical thinking evaluation

Students engage critical thinking and build on their understanding of lithium extraction to evaluate the suitability of a new mine.
Research: The future of lithium mining lesson
in the Elements and Compounds – Lithium Edition unit
Text: Evaluate whether a new direct lithium extraction mine would be suitable for the Maricunga salt flats. Image: Diagram showing the process of extracting lithium from a brine-containing aquifer, with labeled steps for separating and filtering minerals.
