Today students will…

01

Complete

the solution so it functions as intended.

02

Refine

construction quality and user interaction.

03

Finalize

the change record and testing readiness.

What matters before testing
L51 · 03
Core function

Can it do the main job?

Safety

Any loose, sharp, unstable, or unusable areas?

User interaction

Can the intended user understand and perform the task?

Construction

Are key joints, edges, and supports finished appropriately?

Fix functional problems first.Test readiness
Do Not Over-Finish
Decoration cannot rescue weak function
L51 · 04

Wrong priority

Spend the final hour decorating while a key joint, fit, or access problem remains.

Right priority

Finish function → fix quality → clean presentation → decorate only if time remains and it supports the design.

Before leaving, confirm:

“My solution is complete enough for another person to use, and my Criterion C evidence reflects what I actually built.”

Next lesson

Students plan relevant testing methods, collect authentic data, evaluate success, propose improvements, and outline user impact.
