Backwards Design Unit Planner

What This Skill Does

Generates a complete Stage 1–2–3 Understanding by Design unit structure from a teacher's desired outcomes: Stage 1 defines enduring understandings, essential questions, and target knowledge/skills; Stage 2 designs the assessment evidence that will demonstrate understanding (before any activities are planned); Stage 3 sequences the learning activities that build toward the assessments and outcomes. The critical insight of backwards design is that assessment is designed BEFORE instruction — not as an afterthought but as the definition of what success looks like. AI is specifically valuable here because backwards design requires holding all three stages in mind simultaneously and ensuring tight alignment between them — what is assessed must match what is intended, and what is taught must prepare students for what is assessed. Most teacher-designed units plan activities first and assessments last, which produces misalignment.

Evidence Foundation

Wiggins & McTighe (1998, 2005) developed Understanding by Design (UbD), the most widely adopted curriculum design framework in education. The framework's central argument is that curriculum should be designed backward from desired results, not forward from available activities. Stage 1 (Desired Results) defines what students should understand — not just know or do, but genuinely understand at a transferable level. Stage 2 (Assessment Evidence) determines what evidence would demonstrate that understanding — designed before instruction so that teaching targets real outcomes, not just coverage. Stage 3 (Learning Plan) sequences the instruction needed to build toward the assessed outcomes. Wiggins & McTighe (2011) provided practical guidance for unit creation, emphasising that enduring understandings should be transferable ideas worth understanding beyond the unit, and essential questions should be genuinely open — questions that provoke inquiry rather than have predetermined answers. Biggs & Tang (2011) developed "constructive alignment" — the principle that learning outcomes, assessment tasks, and teaching activities must be aligned so that what is assessed is what is taught and what is taught prepares for what is assessed. Hattie (2009) confirmed that clarity of learning intentions and success criteria is one of the highest-leverage factors in student achievement.

Input Schema

The teacher must provide:

• Desired outcomes: What students should understand, know, and be able to do. e.g. "Students will understand how organisms adapt to their environments through natural selection, know key vocabulary (adaptation, variation, natural selection, evolution), and be able to explain how a specific organism's traits relate to its environment."
• Student level: Year group. e.g. "Year 9"
• Unit duration: Length of the unit. e.g. "6 lessons (1 hour each)" / "3 weeks"

Optional (injected by context engine if available):

• Subject area: The curriculum subject
