Bloom’s Taxonomy

Details
Full Name

Taxonomy of Educational Objectives, Cognitive Domain (Revised 2001)

Also known as

Bloom’s Revised Taxonomy; Anderson & Krathwohl Taxonomy

Core Concepts:

Six cognitive levels

A hierarchy of what a learner can do with knowledge, from lower-order to higher-order — Remember, Understand, Apply, Analyze, Evaluate, Create. Higher levels presuppose the lower ones.

Remember

Retrieve facts from memory — recall, recognise, list, name. The floor, not the goal.

Understand

Construct meaning — explain in one’s own words, summarise, paraphrase, give an example. Understanding is not yet mastery.

Apply

Use knowledge in a new situation — execute, implement, solve a fresh case. The first level that proves transfer beyond the example taught.

Analyze

Break a whole into parts and see how they relate — differentiate, attribute, find the edge cases, trace cause to effect.

Evaluate

Judge against criteria — critique, weigh trade-offs, defend a decision.

Create

Assemble parts into something new — design, build, generate a working solution.

Action verbs per level

Each level has its own measurable verbs, which is what turns a vague aim ("understand recursion") into a testable objective ("implement a recursive traversal", "analyse why this base case prevents infinite recursion").

The 2001 revision

Anderson & Krathwohl turned Bloom’s 1956 nouns into verbs and reordered the top two (the original ended Synthesis → Evaluation; the revision ends Evaluate → Create). They also added a second axis — the knowledge dimension (factual, conceptual, procedural, metacognitive) — yielding a two-dimensional taxonomy table.

A heuristic, not a law

The hierarchy is a design aid, not a strict ladder — real tasks mix levels, and Evaluate-vs-Create ordering is debated. Its value is forcing assessment above mere recall, not literal sequencing.

Key Proponents

Benjamin Bloom et al. ("Taxonomy of Educational Objectives", 1956); Lorin Anderson & David Krathwohl ("A Taxonomy for Learning, Teaching, and Assessing", 2001 revision)

When to Use:

  • Writing learning objectives so they name a verifiable cognitive level, not a vague "know about"

  • Designing assessments and quizzes that target higher-order thinking (Apply, Analyze) instead of recall

  • Defining what "demonstrated understanding" means — set the gate at Apply/Analyze, not Remember

  • Reviewing training material or documentation for whether it only informs or also builds skill

  • LLM prompting: "Write quiz questions at the Apply and Analyze levels of Bloom’s Taxonomy"

When NOT to Use:

  • As a rigid linear sequence every lesson must climb in order — it is a design lens, not a script

  • For affective or motor learning — the cognitive taxonomy does not cover attitudes (affective domain) or physical skills (psychomotor domain)

  • 4MAT — 4MAT sequences a lesson (Why/What/How/What-If); Bloom grades the cognitive level each step targets

  • Feynman Technique — explaining-it-back is a concrete check at the Understand level; Bloom names the levels above it

  • Socratic Method — questioning drives learners up the levels; Bloom labels where they are

  • Diátaxis Framework — documentation types map loosely to cognitive levels (tutorial → Apply, explanation → Understand)

Current Status:

  • Two versions circulate: the original 1956 framework (Bloom et al.) uses nouns — Knowledge, Comprehension, Application, Analysis, Synthesis, Evaluation — while the 2001 revision described above uses verbs and puts Create at the top. The standard citable summary of the differences is Krathwohl, "A Revision of Bloom’s Taxonomy: An Overview" (Theory Into Practice 41(4), 2002)

  • An LLM’s training-data prior plausibly blends both versions — material on each is abundant, and many secondary sources mix the level names — so an unqualified "Bloom’s Taxonomy" can anchor to either category set

  • Name the version explicitly: "revised Bloom’s taxonomy (Anderson/Krathwohl 2001)" or "original Bloom’s taxonomy (1956)"
