G2 Design and Technology Paper 2 is a 20-week individual Design Project worth 60% of the 2027 Singapore-Cambridge Secondary Education Certificate (SEC) subject K234. Candidates respond to the released examination question by investigating a need, writing a design brief, exploring and developing ideas, building mock-ups and producing a working prototype. They document the process in an A3 Design Journal and communicate the proposed solution using up to two single-sided A2 Presentation Boards.
This guide explains how to manage the time, develop a real design opportunity, use sketches and mock-ups intelligently and present credible evidence of decisions. It also explains the published 60-mark rubric, common assessment weaknesses and how school supervision works. Every example of a product or design brief below is an original hypothetical exercise, not the SEC project question or a prototype students should copy.

What Is a Design Project Actually Assessing?
A common mistake is to assume the project is simply a craft assignment. A polished object can be attractive but still solve the wrong problem. A more modest prototype may demonstrate a stronger process if the student correctly identifies a need, tests ideas, makes justified decisions and proves that the design functions appropriately.
The project looks at the student as a designer. Did they notice an everyday problem worth addressing? Did they seek relevant information? Did their sketches explore alternatives? Did mock-ups help settle important uncertainties? Is the prototype built to meet the intended function and environment?
The examination assesses decision-making through design, not only the object displayed at the end.
This is why the Design Journal and Presentation Board are not decorative extras. They reveal how the outcome was reached and explain why the solution suits the user.
The Official 2027 Assessment Split
K234 includes two assessed components. Paper 1, the written examination, carries 40%, with three compulsory design-centred questions. Paper 2, the Design Project, carries 60% and takes place across the prescribed twenty-week period, not counting school holidays.
SEAB divides the overall assessment domains approximately into Knowledge with Understanding (40%), Design Thinking Skills (30%) and Design Manipulating Skills (30%). The percentages show their relative assessment importance across both components.
This does not mean the prototype itself is worth thirty marks or that all drawing sheets are assessed only for neatness. The project has a separate detailed 60-mark rubric focused on identifiable stages of designing and prototyping.
Use the published examination-year document, not general D&T advice for a different level.
The Official Paper 2 Sixty-Mark Rubric
The project rubric identifies seven assessed areas:
| Assessment criterion | Maximum marks |
|---|---|
| Planning and monitoring the Design Project | 4 |
| Formulating a design brief and specifications | 6 |
| Generating and developing ideas | 10 |
| Sketching and drawing to design | 6 |
| Using mock-ups to design | 8 |
| Communicating the solution on the Presentation Board | 10 |
| Realising the prototype | 16 |
| Total | 60 |
The marks illustrate why a complete process matters. A prototype is important, but its sixteen marks do not replace the other forty-four marks for planning, investigating, developing, drawing, testing and communication.
The published assessment levels value clear evidence, thoughtful development, appropriate functionality and meaningful quality control.
The Twenty-Week Clock: What It Means
The examination period begins from the question-paper release and lasts twenty weeks, excluding school holidays. It is not the same as a fixed number of calendar days or a promise that every student may work indefinitely.
The school should provide the actual checkpoint schedule, supervision, permitted facilities and submission arrangements. Students should follow those instructions rather than borrow a previous year’s timetable.
A sensible project plan gives time to understand the question, research, sketch, test, build, troubleshoot and prepare the board. Waiting until the final weeks to make the first functioning mock-up creates avoidable risk.
The official rubric rewards monitoring and adapting the time-stages plan, not merely producing a Gantt chart that is never used.
The Difference Between a User Need and a Product Idea
A user need describes a problem a person experiences. A product idea proposes one possible solution.
For example, “The classroom needs a better way to organise shared markers during group activities” describes a practical need.
“Make a wooden marker holder” is already a particular solution. It may be useful, but a designer should first consider whether it actually addresses the user’s problem.
A strong project begins by exploring who has the difficulty, when it occurs, what causes it and which features a solution must have.
This avoids the trap of building something the student already wants to make, then inventing a problem to justify it.
Original Practice Scenario: Shared Art Materials
The following is a fictional non-examination exercise.
A school’s art club keeps a small selection of brushes, rulers and markers on a table. During activities, students have difficulty returning tools to the right place, and the table becomes cluttered.
The student designer wants to create a simple organisational aid for the club using permitted materials and workshop facilities.
The first task is not to sketch a complex box. It is to identify the tools’ dimensions, the number of users, the available table space, how the items are retrieved and which conditions matter for safety and durability.
The project should not claim the club exists or that its students experienced particular failures unless such observations were genuinely collected in an approved setting.
Writing a Design Brief
A design brief communicates the problem and intended design outcome. It should be informed by investigation, not a generic statement such as “I want to make something useful”.
For the fictional art-club scenario, an illustrative brief could be:
“Design and make a compact, stable organiser that allows students to access and return frequently used drawing tools at a shared worktable.”
This sets a user, context and purpose without prematurely dictating every material or shape.
The actual SEC question may establish different constraints. Students must follow those constraints, and the design brief can be refined as evidence improves.
Design Specifications: Turn the Brief Into Checkable Requirements
A design specification states the qualities that would make the proposed solution appropriate.
In the fictional example, potential requirements could include stable placement, accessible compartments, easy-to-understand tool positions, safe edges, suitability for the available workspace and feasible fabrication with school equipment.
A weak specification says only “looks nice” or “works well”. These are difficult to evaluate.
A stronger one asks whether the organiser remains stable under normal use and whether intended users can return tools without confusion. Precise measures should be based on genuine research or constraints, not fabricated figures.
The specification helps the student choose between ideas and evaluate the prototype later.
Research Should Change a Decision
A student may fill the journal with pictures of existing products. That is not necessarily meaningful research.
Ask what each example teaches about user behaviour, materials, mechanisms, dimensions, ergonomics, aesthetics, cost or environmental impact.
For instance, an existing organiser might have a compact footprint but small openings that make objects hard to retrieve. Another might be easy to access but less stable on a narrow table.
The learner should explain what design principle was learned and how it affects the new idea.
The best research is relevant, interpreted and used. Quantity of photographs alone does not demonstrate thoughtful designing.
Generating Ideas: Why There Should Be Alternatives
Designing involves exploring possibilities before choosing a solution. The rubric gives ten marks to generating and developing ideas, reflecting the importance of user needs, functionality and environment.
The fictional organiser might be a free-standing structure, a modular set of holders or an arrangement that fits a particular shared work surface. Each option may have advantages and limitations.
A student should compare ideas against the brief, not select the first because its drawing is attractive.
The purpose of generating alternatives is to expose different ways the same problem can be solved.
Original Idea Comparison
For the fictional organiser, three hypothetical concepts are:
- Concept A: A compact divided tray. It is simple to access, but tools may still be mixed.
- Concept B: A set of labelled vertical compartments. It may improve sorting, but stability and tool fit need testing.
- Concept C: A modular organiser with removable sections. It may support flexible use, but assembly and cost could be more complex.
This comparison is a teaching exercise, not evidence of performance by an actual student.
The appropriate choice depends on user needs, the environment and what a mock-up reveals. A good designer may combine features or reject an initially appealing concept.
Sketching Is a Thinking Tool
The syllabus expects the student to use sketches and drawings to trigger, visualise, develop and refine ideas.
Sketches can explore how an object is held, where moving parts are located, how dimensions relate, and how the final product might work from different viewpoints.
A sketch is not automatically more useful because it is heavily shaded. The important issue is what decision it enables.
For example, side and top views may reveal that a deep compartment makes short brushes difficult to reach. A small annotated sketch showing the problem can be more meaningful than a beautiful perspective drawing with no functional information.
Drawing Details That Matter
Students should use appropriate graphical techniques to communicate relevant features, such as dimensions, orientation, assembly and mechanism where appropriate.
A useful drawing might show how a component is attached, how a lid opens or how a device rests safely on a surface.
Avoid adding arbitrary engineering precision that has not been measured or considered. Drawings should support the design process.
The specific style and tools should follow the teacher’s guidance and K234 content. The goal is to make the idea understandable enough to evaluate or build.
Mock-Ups Are Experiments, Not Miniature Decorations
SEAB gives eight marks to using mock-ups for design. Their purpose is to explore or test ideas and support decisions.
A low-cost mock-up might use permitted classroom materials such as paper, card, foam board, bottle caps or string. It need not resemble a polished finished product.
A designer could test whether an organiser’s compartments are easy to reach or whether a layout becomes unstable when loaded.
The important evidence is what was tested, what was observed, and what changed afterward. A mock-up with no learning outcome may contribute less than one that reveals a significant design weakness.
A Controlled Mock-Up Test
Suppose the designer compares two compartment arrangements in a hypothetical supervised workshop task.
One arrangement holds tools vertically; another places them at an angle. The student should identify the property being compared, such as accessibility or stability, and try to keep other relevant conditions comparable.
Observations might be recorded through structured user feedback or teacher-approved trials.
Do not invent positive results in the report. If the first arrangement proves inconvenient, that is valuable design information.
The student can explain why the next version responds to the observation rather than pretending the original idea worked perfectly.
From Mock-Up to Prototype
A mock-up is commonly used to explore a concept or test a design feature. A prototype is a developed representation intended to demonstrate how the proposed solution actually works.
The syllabus requires the resulting working prototype to accompany the project materials. The prototype should connect to the design brief and specifications.
A student must think about materials, mechanisms, fabrication feasibility, safe use and whether the object can withstand the intended conditions.
It is unwise to begin fabricating a complex prototype before understanding the user’s needs or testing basic dimensions. Earlier mock-ups can prevent expensive or irreversible mistakes.
Prototype Quality Control
The rubric’s highest descriptors value making skills, attention to detail and an outcome that meets intended requirements.
Quality control involves checking measurements, fit, alignment, movement and other functional characteristics relevant to the device.
An organiser that tips over easily fails an important specification even if its surface finish is attractive. A moving mechanism that jams may require redesign, not merely repainting.
The student should document actual testing and corrections in the Design Journal while following school workshop supervision.
Functional accuracy and user suitability matter alongside aesthetics.
A Practical Design Decision Register
Students can keep concise records of important decisions:
| Stage | Question | Evidence to keep |
|---|---|---|
| User need | What difficulty exists? | Approved observations or research |
| Brief | What should the solution achieve? | Clear statement and context |
| Specifications | What must the design do? | Measurable or testable criteria |
| Ideas | Which alternatives were considered? | Sketches and comparisons |
| Mock-ups | What was tested? | Genuine trial outcomes |
| Prototype | How does it function? | Build and testing records |
| Evaluation | Does it meet the brief? | Evidence of strengths and limits |
This register is an organisational method, not a mandatory SEAB form.
It helps students avoid reconstructing their design reasoning after the practical work is finished.
The Design Journal: A Real-Time Record
SEAB calls the journal a real-time document showing how the candidate manages their personal design process.
It should include time-stages plans, investigations, brief and specifications, sketches, drawings, calculations and development toward a prototype.
The syllabus specifically advises candidates not to re-work design sheets. The journal should therefore represent authentic progression, not a completely polished fictional narrative rewritten at the end.
A correction or failed idea is not automatically embarrassing. It can show that the student recognised a problem and responded thoughtfully.
Journal Format: The Exact A3 Requirement
The official format specifies A3-size sheets securely fastened together, or an A3 sketch pad.
Mock-ups and the resulting prototype must be submitted as part of the journal material, along with a mould, jig or former if applicable.
Students should confirm how their school wants these objects packaged and handled. A photograph of a prototype may support explanation, but it is not necessarily a substitute for the required physical item.
Good organisation makes the assessed process traceable without obscuring evidence behind decorative presentation.
The Presentation Board: Communicate the Solution Quickly
The Presentation Board is intended to explain the proposed design solution in relation to the brief and specifications.
It should convey the product’s functional and aesthetic details using appropriate graphical methods. The reader needs to understand what the device is for, how it works and why its features are appropriate to the user and environment.
The official format is up to two single-sided A2 boards. Two are a maximum, not a requirement to fill both with duplicated images.
A board that displays only a glamour shot may fail to communicate the working mechanism or the specific design requirements.
What to Place on a Useful Board
A good board may include, where relevant and allowed:
- the design brief and key specifications;
- a clear overall view of the proposed solution;
- drawings showing important features or use;
- labels explaining function, material or movement;
- contextual imagery showing how the user would interact with it;
- sufficient detail to make the solution understandable.
The exact layout is a design decision subject to school instructions. The board should not become an abbreviated version of every journal page.
It is communication, not a competition to squeeze in as much text as possible.
The Difference Between the Journal and Board
The journal documents the process: investigation, development, decisions, tests and revision.
The board explains the final proposed solution succinctly and convincingly.
A reader of the journal should understand how the student arrived at the solution. A reader of the board should understand the solution and its suitability with relatively little effort.
Students who duplicate all pages across both deliverables may fail to recognise these different purposes.
The two should be coherent without being identical.
How Technology Content Supports the Project
K234 includes materials, manufacturing processes, mechanisms and electronics, in addition to design thinking.
A product using a lever, linkage, gear or electrical control needs an appropriate working understanding of the relevant mechanism. Students should not add electronics simply because they appear advanced.
A simple mechanical design may be more suitable for a user’s actual need than an elaborate gadget with poor reliability or unnecessary cost.
The correct choice depends on the brief, environmental conditions, safety, available resources and the student’s ability to build and explain the mechanism.
Technological complexity is not an assessment goal by itself.
Choosing Materials Responsibly
The syllabus covers working knowledge of common woods, metals, plastics and their characteristics.
Students should consider strength, stiffness, durability, processability, appearance, cost and environmental implications.
For a fictional classroom organiser, a material may be easy to shape but not durable enough for frequent use. Another may be very strong but difficult to process with the facilities available.
A justified choice connects material property → user requirement → feasible process.
Avoid selecting a material solely because it looks professional in a photograph.
Safe Workshop Practice
Design and Technology coursework involves tools and materials that can be hazardous if used incorrectly.
All cutting, drilling, soldering, machining, heating or electrical work should follow the school’s approved workshop procedures, equipment controls and trained supervision.
This article does not provide hazardous fabrication instructions or encourage students to use restricted equipment at home.
If a design requires expertise beyond the syllabus, SEAB says centres should ensure any extended learning is within the candidates’ means. A design should not depend on inaccessible tools or unsafe experimentation.
Safety and feasibility are part of sound design reasoning.
What a Real Time-Stages Plan Should Show
A time-stages plan identifies major phases and provides a way to monitor progress. The syllabus mentions Gantt charts as one example.
But a decorative chart made at the beginning and never revised is weak evidence of project management.
The plan should allow the student to compare what was expected, what actually happened and what changed in the next steps.
If a mock-up reveals a stability problem, the learner may need to revise the development schedule. Recording that decision can demonstrate real management.
The official assessment favours thoughtful monitoring, not a perfect prediction of every week.
A Fictional Twenty-Week Planning Illustration
This is not the prescribed 2027 school calendar. It merely shows a possible sequence of milestones:
- Early stage: Read the released question, investigate user needs and define a brief.
- Next stage: Create specifications and generate alternatives.
- Middle stage: Sketch, compare, construct mock-ups and evaluate test results.
- Later stage: Refine the selected idea and develop the prototype under supervision.
- Final stage: Complete quality checks, verify journal records, prepare the board and submit on time.
A student’s actual work may require iteration between stages. The project is not a rigid assembly line.
The precise release date, checkpoints and practical sessions come from the school.
Why Revisiting Earlier Decisions Is Valuable
A thoughtful student may discover that a specification was unrealistic. They should explain what evidence prompted the change and how the new specification better serves the user.
This does not mean rewriting an earlier journal page to pretend the improved idea existed from the beginning.
The real sequence of learning is initial assumption → new evidence → changed decision.
Showing that development can demonstrate the maturity of the design process. It is a stronger story than an artificially flawless record in which no uncertainty ever arose.
Assessing a Prototype Against the Brief
After making the prototype, evaluate it against the actual design specifications.
If the goal was compact storage, measure or compare the device’s occupied space. If the goal was easy retrieval, use an approved test or relevant observation. If the goal was safety, explain what hazards were considered and which safeguards were built into the design.
Do not claim that users love the device without appropriate evidence.
A prototype can meet some requirements while revealing a weakness in another. That is an honest result from which design decisions can improve.
The Difference Between “Works” and “Works Well”
A product may function mechanically but be impractical for its intended use. For example, a lid may open but require excessive force from the user. A stand may hold a device but occupy too much desk space.
The test should ask how reliably and appropriately it performs under expected conditions.
A student should consider whether the prototype demonstrates the intended function, not merely whether one component moves.
This is the link between quality control and user-centred design.
Common Project Mistake 1: Starting With a Product
The candidate chooses to build a gadget and invents a problem to justify it.
Repair by investigating the user’s genuine need and defining a brief before committing to a particular form.
Common Project Mistake 2: A Vague Specification
Requirements such as “modern”, “nice” and “convenient” do not provide enough basis for testing.
Repair by stating observable or measurable properties relevant to the problem.
Common Project Mistake 3: Many Pictures, Little Analysis
Research pages reproduce existing designs but do not show what was learned.
Repair by explaining how evidence influenced decisions and alternative ideas.
Common Project Mistake 4: Sketches Only for Decoration
Drawings show a final appearance but no meaningful concept development.
Repair by using sketches to test form, layout, operation and dimensions.
Common Project Mistake 5: Mock-Ups That Test Nothing
A small model is made only to tick a requirement.
Repair by specifying the question a mock-up is intended to answer and recording the outcome.
Common Project Mistake 6: Journal Reconstructed After Completion
The project record is rewritten to look like a seamless success.
Repair by documenting genuine progress and following SEAB’s advice not to re-work design sheets.
Common Project Mistake 7: An Unreliable Prototype
The object looks attractive but fails to meet basic functional criteria.
Repair through appropriate testing, quality control and revised specifications.
Common Project Mistake 8: Presentation Board Without Function
The board shows images but does not explain how the design operates.
Repair by communicating the key functional and aesthetic features clearly.
Common Project Mistake 9: Unrealistic Technology
A student chooses mechanisms or electronics beyond the available time and resources.
Repair by choosing a feasible solution within the syllabus and supervised facilities.
Common Project Mistake 10: No Monitoring of the Twenty-Week Plan
Important tasks are left until the end.
Repair by maintaining an updated time-stages plan and reacting early to difficulties.
The Fencing Method for Design Thinking
The eduKateSG Fencing Method begins with one bounded user problem.
First, ask the learner to describe a need without naming a product. Next, add a specific context and requirement. Then ask for two different concepts, with reasons for their advantages and limits.
Introduce a mock-up test to compare one important characteristic. Only after the learner understands the decision should the next technical challenge be added.
Finally, give a new design need and ask the student to apply the process independently.
The goal is transferable design judgement, not the repetition of one successful classroom object.
A Four-Week Pre-Project Skills Cycle
Week 1: User Needs and Briefs
Practise recognising everyday design opportunities. Turn broad complaints into specific, ethical and feasible briefs and specifications.
Week 2: Ideas and Visual Communication
Explore alternatives through quick sketches and comparisons. Ask what each variation changes and which user needs it addresses.
Week 3: Mock-Up Reasoning
Use approved safe classroom materials to compare concepts. Record the intended test, actual observations and decisions.
Week 4: Project Monitoring and Explanation
Prepare a hypothetical time-stages plan, basic journal layout and presentation-board outline. Practise explaining how an idea moved from problem to prototype.
This is a preparation cycle, not the actual twenty-week examination task, and does not replace school-supervised coursework.
What Parents Can Do Without Completing the Coursework
Parents can ask “What user problem are you solving?”, “What evidence led you to this design?”, “What did the mock-up teach you?” and “How will you test whether it works?”
Those questions support reflection while preserving the student’s ownership of the project.
Do not fabricate observations, build the assessed prototype for the child or reconstruct the journal to conceal gaps. Ask the school which kind of outside assistance is permitted.
eduKateSG’s broader 3-pax teaching model promotes focused questioning and independent reasoning; specialist design-project supervision remains the school’s responsibility.

Final Takeaway: A Good Design Project Proves Its Reasoning
The 2027 G2 K234 Design Project assesses a twenty-week, student-owned process from identifying a need to communicating and demonstrating a feasible prototype. Its sixty marks are distributed across planning, evidence, ideas, drawing, mock-ups, communication and making.
The most dependable approach is to keep the investigation genuine, use mock-ups to resolve uncertainty, record decisions as they happen, and evaluate the final outcome against the user’s actual needs. The finished object matters because the student can show how and why it came to exist.
