How to Write Better Learning Objectives (And Why Bloom's Taxonomy Actually Helps)

Most learning objectives I've seen on lesson plans say something like "Students will understand photosynthesis" or "Students will appreciate the causes of World War I." Those are intentions, not objectives. If you've ever written a lesson and then wondered why your assessment didn't quite measure what you taught, the objective is usually why.

A learning objective is a promise — to yourself, to your students, and to whoever's reading your plan. A vague promise leads to a vague lesson and a vague assessment. Here's how to write objectives that actually do the work they're supposed to do.

The Problem With "Understand" and "Know"

The verbs "understand," "know," "appreciate," and "be aware of" are the enemy of good lesson planning. They sound fine on paper, but they don't tell you — or your students — what they're actually supposed to do.

Can you observe someone "understanding" something? Not directly. You can observe them explaining it, applying it, comparing it to something else, or analyzing a specific case. Those are verbs you can build an assessment around.

This is where Bloom's Taxonomy comes in — not as a bureaucratic hoop to jump through, but as a genuinely useful tool for picking the right verb.

Bloom's Taxonomy Without the Jargon

Bloom's describes six levels of thinking, from simpler to more complex:

Remember — recall facts: define, list, identify, name, recall

Understand — explain in your own words: explain, summarize, describe, classify, paraphrase

Apply — use knowledge in a new situation: calculate, demonstrate, solve, use, construct

Analyze — break apart and examine: compare, differentiate, examine, contrast, organize

Evaluate — make judgments: argue, defend, critique, justify, assess

Create — produce something new: design, develop, write, produce, formulate

When you're writing your objective, pick a verb from the level that matches what you actually want students to do. A vocabulary lesson probably targets Remember or Understand. A problem-solving activity targets Apply or Analyze. A Socratic seminar might target Evaluate.

The Formula That Works

Here's a simple formula for writing learning objectives:

Students will be able to [observable verb] [specific content] [condition or criteria, if relevant].

A few examples:

• "Students will be able to identify the three main causes of World War I from a primary source document."
• "Students will be able to calculate the area of composite figures using the formulas for rectangles and triangles."
• "Students will be able to compare the narrative perspectives in two short stories and explain how perspective affects meaning."

Notice what's different from "understand" objectives: you can directly observe and measure each of these. You know exactly what the student needs to do, and so does the student.

One Objective Per Lesson (Usually)

A common mistake is writing three or four learning objectives for a single lesson and treating them as a checklist. More objectives don't make a better lesson — they usually make a scattered one.

For most lessons, aim for one primary objective. If your lesson has two distinct phases that build on each other, two objectives can make sense. But if you find yourself writing five objectives, that's a sign you're planning a unit, not a lesson.

Let Students See the Objective

Writing the objective matters. So does communicating it clearly to students.

"Today's objective is on the board" doesn't cut it. Students need to understand what they're working toward and why. Some teachers frame the objective as a question: "By the end of today, you should be able to answer: What three factors contributed to the fall of Rome?" That's more engaging than a passive statement.

Even better: at the end of class, ask students to self-assess against the objective. "On a scale of 1-3, how confident are you that you can explain the three causes we identified today?" That feedback loop is quick, informative, and teaches students to monitor their own understanding.

Matching Objectives to Assessment

The biggest payoff of well-written objectives is that they make assessment almost automatic. If your objective is "students will be able to solve two-step equations," your exit ticket is just: give them two-step equations to solve. If your objective is "students will be able to compare the themes in two texts," your assessment is: give them two texts and ask them to compare themes in writing.

When you find yourself unsure what to assess after a lesson, it's almost always because the objective was too vague. Go back, rewrite the objective with a clearer verb, and the assessment writes itself.

A Note on Standards

Many teachers write objectives that are just reworded standards. That's not wrong, but it misses an opportunity. Standards describe what students should know and be able to do by the end of a unit or year. Your daily objective should describe what specific step toward that standard you're hitting today.

If the standard is "analyze how an author's choices regarding structure contribute to the meaning of a text," your lesson objective might be "students will be able to identify how the sequence of events in a narrative creates tension" — a specific, day-sized chunk of that larger goal.

Use a Tool to Build the First Draft

Planning lessons with well-written objectives takes practice. One thing that helps is having a structured starting point. When I started using LessonDraft to draft lesson plans, I noticed it consistently prompted me to think through the objective before anything else — which is exactly the right order. You write the objective, then build the lesson to match it, then design the assessment to measure it.

That sequence — objective → instruction → assessment — is the whole game. Get the objective right, and the rest follows.

Your Next Step

Go back to your last three lesson plans and look at the objectives. Can you observe and measure each one? If not, rewrite them using the SWBAT formula with a Bloom's verb. Then look at your assessment and see if it actually measures the objective you wrote. That single alignment check will tell you more about your lesson design than any rubric.
