Essential question
What can you learn about your own design by walking through it at full size that you cannot learn on a screen?
What students learn and show
Learn: Walking a design at full size exposes circulation, clearance and sight-line problems that can then drive revisions.
Show: Submit a revised design whose changes each trace to a recorded full-size observation.
Objectives
Print a personal CAD design at true 1:1 scale
Evaluate the design by physically moving through it at a calm pace
Identify at least three spatial problems invisible on screen
Produce and justify a revised design
Before this lesson students should: Can produce a scaled CAD drawing and export to PDF at a known scale.
Materials and prep
A student CAD export printed at 1:1, or the key zone taped at full size
Markers
Tape measures
Peer-walk critique rubric (in the packet)
Notebooks
Prep (about 20 min to print, 60 min to tape)
Students export their plan to PDF at a stated scale ahead of time.
Order 1:1 prints of selected designs, or tape the key zone (one room plus its circulation) of each design.
Copy the peer-walk rubric.
Space: One design zone per team (about 200-400 sq ft) on studio floor, gym or outdoors.
Grouping: Individual designers, peer pairs.
Ways to run it: Painter's tape on the floor; 1:1 printed floor plan
Lesson procedure
Teacher model: Instructor walks one sample plan and narrates: 'Drawn: 42-in hall. Walked: two people cannot pass with a bag. Evidence: measured 40 in between door casings.' Logs it on the rubric.
Guided practice: Pairs walk the sample together and log one item per rubric criterion before walking their own designs.
Students export their current studio design to PDF; confirm it prints at true 1:1 scale.
Walk your own plan silently first, at a calm pace. Mark every spot that reads wrong on foot — a hallway that pinches, a sight-line that surprises, a door that conflicts.
Peer walk: partners walk each other's prints against the rubric — scale accuracy, circulation, sight-lines, clearances.
Write a critique before revising: what changed between what you drew and what you felt?
Revise, and where the program allows, re-print the corrected sheet. The loop — draft, walk, revise — is the lesson.
Checks for understanding
Ask: Scale accuracy: what are you checking? Look for: That dimensions you drew survive being walked and measured at true size.
Ask: Circulation: what are you checking? Look for: That people can move and pass where the plan implies they can.
Ask: Revision quality: what are you checking? Look for: What changed between draft one and draft two, and which walk observation drove it.
Exit ticket
List three problems found on foot, each with a measurement or observation. Answer: Three specific, checkable items.
For one revision, state the change and the observation that justified it. Answer: A clear causal link.
Scoring: Rubric (each 0-2): scale accuracy, circulation, clearances, sight-lines, revision rationale. 8-10 = strong.
Common misconception
Students may think: The walk confirms the design was right.
Address it: Treat the walk as a test that can fail; record surprises, not just confirmations.
Supports and extensions
Learning support: Provide the rubric as a checklist with one criterion at a time; pair with a peer scribe.
Multilingual learners: Pre-teach 'circulation', 'clearance', 'sight-line' with a labeled floor diagram; allow critique in sentence frames.
Mobility and access: Students who do not walk can roll, direct a partner, or review a 1:20 physical model; critique criteria stay the same.
Extension: Run a second loop after revision to catch new problems the fix introduced. Challenge: compare a peer's on-screen critique to their on-foot critique and report where they diverged.
Transfer task: Run the same walk on a classmate's design from another studio.
Spaced review: At final review, re-walk the revised zone and log any new problems the fix created.

Why this approach
Spatial ability measured at age 13 predicted creative and technical accomplishments decades later. Limit: Correlational; it does not test full-size design critiques.
