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
National Research Council (NGSS writers), USA.
Effectiveness
John Hattie's Visible Learning and the Science of How We Learn (2013) 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.
