Bloom's taxonomy

The Knowledge Dimension:

1. Factual knowledge - terminologies, basic elements and other listable knowledge
2. Conceptual knowledge - underlying principles, concepts, frameworks and relationships
3. Procedural knowledge - techniques and methods - how to - practice
4. Metacognitive knowledge

The Cognitive Process Dimension:

First 3 can be called - LOTS - Lower Order Thinking Skills Last 3 can be called - HOTS - Higher Order Thinking Skills

The last three are all fairly complex intellectual tasks. So we got inverted pyramid.

Most taxonomies—and maybe all—eventually breakdown.

Taxonomy is how we arrange things
