Build + Refine · Day 2

Finishing means more than adding decoration: strengthen weak areas, improve function, and prepare the product for authentic testing.

Today students will…

01

Complete

the product using strong technical skills.

02

Refine

weak areas found through informal checks.

03

Finalize

the change record and readiness for formal testing.

Formal Criterion C evidenceMaking remains priority

Refinement has a purpose
L36 · 03
Loose joint

Rebuild or reinforce the connection.

Unstable base

Adjust support or footprint.

Awkward access

Improve clearance, grip, or opening.

Rough finish

Trim or secure areas that interfere with safe use.

Fix problems that affect use or quality first.Function before decoration
Informal Check
Test before the formal test

Performance

Can it do the core job once?

Repeat

Can it do the job several times without immediate failure?

User

Can a partner understand how to use it?

INFORMAL ≠ FINAL D TEST

Use quick checks to find problems now. Formal testing and evaluation happen in Lesson 37.

Avoid using final assessment data too early.Refinement evidence
Build Workshop
Day 2
L36 · 05
Build

Finish the function, refine the quality, record real changes.

STEP 01

Finish

Complete missing functional features.

STEP 02

Check

Run quick performance/user checks.

STEP 03

Refine

Fix one or two evidence-based weaknesses.

Main workshopC.ii–C.iv
Final C Check
Does the solution function as intended?
L36 · 06

Plan

Was the plan used as the starting sequence?

Skill

Are taught practical techniques visible in the finished work?

Function

Can the solution perform the intended core job?

Changes

Are real changes listed clearly?

Bring success criteria forward
L36 · 07

Tomorrow you will test against your success criteria.

For each criterion, decide: What test could produce evidence — a count, measurement, time, pass/fail result, or user rating/comment?
No need to complete D packet yet.Preview testing
Exit + Cleanup
Ready for authentic testing
L36 · 08

Before cleanup, confirm:

“My product is complete enough for another person to use and for me to collect honest test data.”

Next lesson

Students plan simple relevant tests, collect authentic performance/user data, evaluate success, propose improvements, and outline impact.
