Backward Design in Practice: Planning Units That Actually Build Understanding

Understanding by Design (UbD), developed by Grant Wiggins and Jay McTighe, is the most well-supported framework for unit planning in secondary education. Its central insight is simple and transformative: plan backward from what you want students to understand and be able to do, not forward from what you want to cover.

Most curriculum design is forward design: teachers plan what they'll teach chronologically, then assess at the end to see what students learned. Backward design reverses this: start with the intended learning outcomes, design assessments that would provide evidence of those outcomes, then plan instruction that leads to them.

The difference is not merely philosophical. It produces structurally different units — ones where every activity has a clear connection to the intended outcome, rather than units that cover content and hope the big ideas stick.

The Three Stages

Stage 1 — Desired Results: What do you want students to understand, know, and be able to do? UbD distinguishes between three types of desired results:

• Established goals: Standards, benchmarks, curriculum requirements
• Understandings: The big ideas students should grasp — what they should be able to explain in their own words long after the unit ends ("Students will understand that...")
• Essential questions: Questions that frame the unit's inquiry, that are genuinely complex, and that students will engage with repeatedly at increasing depth

The understandings and essential questions are the hardest to write and the most valuable. "Students will understand that colonialism created economic and political structures that persist in former colonies" is an understanding. "What is the legacy of colonialism?" is an essential question that this understanding addresses.

Stage 2 — Assessment Evidence: What would provide evidence that students have achieved the desired results? UbD recommends distinguishing between:

• Performance tasks: Authentic tasks that require students to demonstrate understanding by applying it in a new context — not just recalling information. A performance task for the colonialism unit might ask students to analyze the economic structure of a specific country using the concepts from the unit.
• Other evidence: Quizzes, tests, observations, homework that supplement the performance task

The key question for Stage 2: Would doing well on this assessment require the understanding you named in Stage 1? If students can pass the test by memorizing without understanding, the assessment doesn't align with the desired result.

Stage 3 — Learning Plan: Only after completing Stages 1 and 2 should instruction be planned. The learning plan is designed to lead students toward the Stage 1 understandings through activities that prepare them for Stage 2 assessments.

The WHERETO framework helps structure learning experiences:

• Where is the unit going? What is expected?
• Hook students with engaging opening experiences
• Equip students with knowledge and skills they need
• Rethink and revise through new perspectives
• Evaluate their work and self-assess
• Tailor to individual needs
• Organize for optimal engagement and effectiveness

Essential Questions That Generate Real Inquiry

The essential question is one of UbD's most useful tools and one of its most frequently misimplemented. An essential question should:

• Be genuinely open (no obvious right answer)
• Invite inquiry and discussion
• Connect to big ideas in the discipline
• Be revisable as understanding deepens

Examples of real essential questions:

• "Is war ever justified?"
• "What makes a mathematical proof convincing?"
• "How do environments shape human cultures, and how do human cultures shape environments?"
• "When does a narrator's perspective make a story more or less trustworthy?"

Questions that aren't essential (too narrow, too factual, or too obvious):

• "What were the causes of World War I?"
• "What is the Pythagorean theorem?"
• "How does climate affect agriculture?"

The test: would engaging with this question repeatedly, across multiple texts and experiences, develop deeper understanding over time? If yes, it's probably an essential question.

Common Backward Design Mistakes

Writing assessments that test memory, not understanding: A test of factual recall doesn't align with understandings, even if the facts are true and important. Assessments should require the kind of thinking the understanding demands.

Vague understandings: "Students will understand the Civil War" is not an understanding — it's a topic. "Students will understand that the Civil War's causes were rooted in the economic and moral conflict over slavery, which made compromise impossible" is an understanding.

Essential questions that are really just content questions: "What was the significance of the Magna Carta?" is a content question with a fairly determined answer. "How does law constrain power?" is an essential question the Magna Carta helps answer.

LessonDraft can help you design backward-designed units, essential questions, and performance tasks for any subject and grade level.

Backward design changes the relationship between instruction and assessment from "teach, then test" to "decide what matters, assess it authentically, then teach toward it." The units it produces are more coherent, more purposeful, and more reliably connected to the learning that actually lasts.
