While Bloom's taxonomy categorizes cognitive skills from basic recall to higher-order thinking (Remember, Understand, Apply, Analyze, Evaluate, Create), the SOLO taxonomy assesses the depth and complexity of understanding, moving from surface to deep learning. Unlike Bloom's fixed hierarchical model, SOLO emphasizes a developmental progression that reflects a student's ability to integrate and generalize knowledge.
