What is the highest level of the SOLO Taxonomy?

Correct answer: Extended Abstract. The SOLO Taxonomy has five levels (prestructural, unistructural, multistructural, relational, and extended abstract); extended abstract is the highest because learners generalize and apply ideas to new situations.

• Relational: Relational is the fourth level, where ideas are integrated into a whole.
• Multistructural: Multistructural is the third level, where several ideas are listed without being connected.
• None of these: “None of these” is incorrect because extended abstract is the highest level.
