CCEA GCSE Technology and Design: complete guide to Unit 1, the Unit 2 options and the design project

CCEA GCSE Technology and Design is the Northern Ireland GCSE in designing and making technological products, set by the Council for the Curriculum, Examinations and Assessment. It is assessed through two written units and a Design and Manufacturing Project. This page is the index: below is a map of the study modules, the unit and option structure, the calculations you must do, and how to study each part, with a link to every dot point.

The CCEA Technology and Design content

The specification has a compulsory core, a choice of optional area, and a major design project.

Unit 1: Technology and Design Core Content (compulsory, 25%)

The shared foundation. It covers designing (the design process, ergonomics, communicating ideas, evaluation and the influences on design), materials and manufacturing, CAD/CAM, mechanisms and motion, pneumatic systems and control, and electronic and control systems.

Unit 2: Optional Areas of Study (one option, 25%)

Candidates specialise in Option A Electronic and Microelectronic Control Systems, Option B Mechanical and Pneumatic Control Systems, or Option C Product Design, each deepening the matching core area.

Unit 3: Design and Manufacturing Project (controlled assessment, 50%)

The candidate designs and makes a product, evidenced by a design folder and a manufactured outcome.

The seven study modules

We split the content into seven focused modules so that each examinable point gets its own answer page.

Designing

The iterative design process, ergonomics and anthropometrics with percentiles, communicating ideas through sketching and working drawings, evaluation and product analysis, and the outside influences on design including sustainability and the six Rs.

Materials and manufacturing

Material categories and properties (metals, polymers, timber, composites), smart and modern materials, shaping and forming (line bending, vacuum forming, injection moulding), joining and assembly, finishing, scales of production with jigs and templates, and health and safety.

Computer-aided design and manufacture

CAD for drawing, modelling and testing, and CAM with CNC machines (laser cutter, router, 3D printer), additive versus subtractive manufacture, and the advantages of an integrated CAD/CAM system.

Mechanisms and motion

The four types of motion, levers and the principle of moments, mechanical advantage, gears and gear trains, belt and chain drives, and motion converters such as cams, cranks, rack and pinion and screw threads.

Pneumatic systems and control

The compressed-air supply, single and double-acting cylinders, the force equation $F = pA$, directional control valves (3/2 and 5/2) and controlling cylinder speed.

Electronic and control systems

The systems approach (input, process, output), components and Ohm's law, input sensors and the voltage divider, output devices and the transistor switch, logic gates with truth tables, and microcontrollers with timing circuits.

Optional routes and the design project

The three Unit 2 options and how each builds on the core, and an overview of the Unit 3 Design and Manufacturing Project.

The calculations to master

Technology and Design is a numerate subject. Be fluent with:

• Moments: $\text{moment} = \text{force} \times \text{distance}$, and balance $F_1 d_1 = F_2 d_2$.
• Mechanical advantage: $\text{MA} = \dfrac{\text{load}}{\text{effort}}$.
• Gear ratio and velocity ratio: $\dfrac{\text{driven}}{\text{driver}}$, and output speed $= \dfrac{\text{input speed}}{\text{ratio}}$.
• Pneumatic force: $F = p \times A$.
• Ohm's law: $V = I R$, including sizing an LED's current-limiting resistor.

Assessment structure

CCEA GCSE Technology and Design is assessed by two written papers plus the controlled-assessment project. The written papers are tiered (Foundation and Higher).

• Unit 1 - a written paper on the core content (25%).
• Unit 2 - a written paper on the chosen optional area (25%).
• Unit 3 - the Design and Manufacturing Project, a controlled assessment with a folder and a made outcome (50%), marked by the centre and moderated by CCEA.

How to study CCEA Technology and Design

The subject rewards precise definitions, confident calculations and clear design thinking.

1. Work from the specification. Each statement is a checklist; questions are written from it.
2. Learn the contrasts. Brief versus specification, thermoplastic versus thermoset, single versus double-acting cylinder, AND versus OR, additive versus subtractive.
3. Drill the calculations. Moments, gear and velocity ratios, $F = pA$ and Ohm's law, with full working.
4. Revise your option in depth. Master the core module behind your Unit 2 option.
5. Plan the project around the design process. Evidence research, ideas, development, planning, making and evaluation.
6. Practise past papers. Attempt CCEA papers for your tier under timed conditions and mark against the official schemes.
