Bloom's Taxonomy in Lesson Planning: How to Actually Use It (Not Just Post It on Your Wall)

Bloom's Taxonomy is probably the most widely known framework in education. It's on the wall in most classrooms, in most teacher preparation textbooks, and in most staff development presentations. It is also, in practice, frequently ignored — treated as a poster rather than a planning tool.

This is a missed opportunity. When used deliberately in lesson planning, Bloom's does two things that matter: it clarifies what you're actually asking students to do, and it reveals when you're asking students to do too little.

The Framework, Briefly

Benjamin Bloom's original 1956 taxonomy organized cognitive learning objectives into six levels, from lowest to highest order of thinking:

1. Knowledge — Recall of facts and information
2. Comprehension — Understanding and explaining what something means
3. Application — Using knowledge in a new situation
4. Analysis — Breaking down, comparing, examining relationships
5. Synthesis — Creating something new by combining ideas
6. Evaluation — Making judgments with reasoned criteria

Anderson and Krathwohl revised the taxonomy in 2001 to use verbs and added a slight structural change:

1. Remembering — Recall (define, list, name, recall, recognize)
2. Understanding — Explain in own words (describe, explain, summarize, interpret)
3. Applying — Use in context (use, solve, demonstrate, illustrate, apply)
4. Analyzing — Examine relationships (compare, contrast, differentiate, organize, infer)
5. Evaluating — Make judgments (assess, judge, defend, critique, justify)
6. Creating — Produce something new (design, construct, create, compose, develop)

The revised taxonomy is the version most commonly used in current curriculum design.

The Planning Problem Bloom's Reveals

Most classroom assessments and activities live at the bottom two levels: remembering and understanding. Students recall definitions, identify examples, and explain back what they were taught. This is necessary but not sufficient for deep learning or durable retention.

When you audit your lesson plans against Bloom's, you often discover that the majority of your tasks are Remembering and Understanding, with Application appearing occasionally, and Analysis, Evaluation, and Creating appearing rarely or not at all.

This matters for two reasons:

1. Retention is stronger at higher levels. Students who apply, analyze, and create with knowledge retain it significantly longer than students who only recall it.
2. Transfer requires higher-order processing. Students who can only recall and recite will struggle when the problem looks different than the one they practiced. Higher-order engagement builds the flexible thinking that transfers.

Writing Learning Objectives With Bloom's

The most practical use of Bloom's in lesson planning is writing objectives that specify the cognitive level you're targeting.

Weak objective: "Students will understand photosynthesis."

What level is "understand"? It could mean recall a definition, explain the process, diagram it, or compare it to cellular respiration. It's ambiguous.

Strong objectives at different levels:

• Remembering: "Students will recall and define the inputs and outputs of photosynthesis."
• Understanding: "Students will explain in their own words why plants need both sunlight and CO₂."
• Applying: "Students will use the photosynthesis equation to predict what happens when a plant is placed in different light conditions."
• Analyzing: "Students will compare the structures of photosynthesis and cellular respiration and explain why the two processes are complementary."
• Evaluating: "Students will assess competing claims about why certain plants are more efficient photosynthesizers and defend a conclusion with evidence."
• Creating: "Students will design an experiment to test a specific variable affecting photosynthesis rate."

Notice how specifying the level makes it completely clear what students will be doing, and what the assessment task must be.

Designing Tasks That Match the Level

Once you've specified the level, design tasks that actually require it:

Remembering tasks: Flashcards, recall quizzes, vocabulary matching, fill-in-the-blank, identification tasks

Understanding tasks: Written summaries, concept mapping, oral explanation ("teach it back"), paraphrasing, asking students to give new examples

Applying tasks: Word problems in new contexts, lab procedures, case studies, using a formula or process on unfamiliar examples

Analyzing tasks: Venn diagrams, compare-contrast essays, categorization activities, identifying causes and effects, examining logical structure

Evaluating tasks: Debates, judgment tasks ("which policy was more effective and why"), peer critique with rubric, argument essays that require justification

Creating tasks: Original writing, design projects, experiments, simulations, video/podcast creation, developing a plan or solution

Common Mistakes When Using Bloom's

Confusing activity type with cognitive level. A group project can be at the Remembering level if students are just recalling and presenting facts. A multiple-choice quiz can reach the Analyzing level if questions require comparing and differentiating. The activity format doesn't determine the cognitive level — the cognitive demand of the task does.

Treating higher is always better. Not every lesson needs to reach Creating. Remembering and Understanding are necessary precursors. If students don't know the facts, analysis is impossible. Match the cognitive level to the learning goal, not to a general belief that higher is better.

Spending the whole unit at Remembering and rushing to Creating at the end. Higher-order thinking requires a knowledge base. Build lower-level knowledge first, then design the progression toward higher levels as knowledge becomes solid.

Bloom's in Unit Planning

Bloom's is most powerful at the unit level, not just the lesson level. A well-designed unit deliberately sequences cognitive levels:

• Early lessons: Remembering and Understanding — building the knowledge base
• Middle lessons: Applying and Analyzing — working with knowledge in context
• Late lessons: Evaluating and Creating — producing something that demonstrates sophisticated understanding

The Point

Bloom's Taxonomy is a description of what thinking actually is. Using it deliberately in planning means you know exactly what kind of thinking you're asking students to do — and you can audit whether you're consistently doing the easy thing (recall) or the hard, valuable thing (analyze, evaluate, create).

Post it on your wall. Then use it in your planning document.
