Did you know? Prototype feedback becomes useful when a D&T student connects it to a design requirement and a specific next change. Help a Secondary 2 learner record what happened during an authorised test, distinguish observation from opinion and decide what evidence a revised design would need.
Try this original planning example: a tabletop reminder-card holder must keep a supplied card visible and allow removal. During an imagined teacher-approved trial, the card slips forward when inserted. “Make it nicer” does not address that observation; investigating the support and then testing a suitable revision could.
Follow the actual school brief, prototype task and safety instructions. Our scenario supplies fictional feedback, not results from a real product or instructions for home fabrication. Lower-secondary D&T is not identical to SEC coursework, and PG1–3 admission groups do not specify an examination-level design task.

Choose the question closest to today’s difficulty. Each section offers a small action and a way to check understanding.
1. Return to the requirement before revising
2. Record an observation separately from a judgement
3. Investigate before choosing a favourite fix
4. Retest the revision against relevant requirements
Contents: six practical learning steps
State what the prototype must do. In our example, visibility and removal are separate requirements. A revision that holds the card securely but makes removal difficult may improve one function while creating another problem.
Use the requirements authorised for the actual brief. Do not invent a strict performance threshold after seeing the result simply to make the prototype pass. If a requirement is vague, ask the teacher how it should be interpreted or checked.
“The card slipped forward during insertion” describes the fictional observation. “The design is terrible” adds a broad judgement that does not identify a repair. Record relevant conditions, such as the supplied card and how it was inserted, where the task requires them.
Keep user comments too, but identify them as comments. Someone saying “I prefer blue” offers a preference, not evidence that the card holder performs its job. Preference can matter when the brief makes it relevant; it should not replace functional evidence.
Ask what could account for the slipping. The support arrangement, dimensions or material behaviour might matter, but the fictional observation alone does not establish the cause. Inspect the authorised model and seek teacher guidance rather than guessing a mechanism confidently.
Consider more than one feasible revision at the planning stage. An annotated sketch can explain which feature would change and why. Do not assume that every improvement requires rebuilding the whole object or adding more material.
A paper mock-up may help explore fit, layout or access, but it does not automatically establish the strength of a different final material. Label the question the model can answer. Avoid treating every kind of prototype as a complete miniature of the finished product.
Any tools, machinery, heating, electrical parts or materials processing must follow school supervision and safety rules. Parent support can stay with interpreting feedback and discussing sketches. This guide does not authorise an unsupervised home workshop.
For an approved revision, use a comparable test of the same requirement and record the outcome honestly. Also revisit other requirements affected by the change, such as card removal. A fix is incomplete if it solves one problem by concealing another.
Do not erase the original difficulty from the design record. Showing what was observed, why a change was chosen and what the next test found makes the learning visible. Follow the school’s actual expectations for documentation rather than assuming one universal portfolio format.
Finish with a concise account: the requirement, observed difficulty, proposed change and result or planned retest. If the revision has not been tested, label it as proposed rather than successful. That distinction protects the accuracy of the design explanation.
Use a fresh teacher-approved feedback item to check independence. Can the learner separate preference, observation and requirement without your prompts? Later SEC study must follow the actual D&T syllabus, subject level, examination year and school coursework instructions.
