There are three key points summarized:
1) Bloom's taxonomy outlines six levels of cognitive learning - remembering, understanding, applying, analyzing, evaluating, and creating. Certain verbs are appropriate for assessing each level.
2) Kendall and Manzano's new taxonomy has three domains - information, mental procedures, and psychomotor procedures - that are processed through six levels including retrieval, comprehension, analysis, knowledge utilization, metacognitive systems, and self-systems.
3) Both taxonomies aim to classify learning objectives and assessment according to increasing complexity, though Kendall and Manzano's model divides domains and levels more distinctly.
