GCSE Design and Technology
Mae disgrifiad y cymhwyster yn Saesneg yn unig, gan ei fod wedi ei gymryd o fanyleb Saesneg CBAC.
Learners type short and extended answers in an on-screen examination. In a 40 hour design project worth 70% they write a design brief and specification, annotate and justify ideas, and evaluate their prototype using feedback from users. Numeracy is practical and constant: accurate measuring and marking out within tolerances in every pathway, costing and material estimates in Fashion and Textiles, and formula-based mechanical and electronic calculations in Engineering Design. The single biggest thing Key Stage 3 should build is precise measuring in millimetres against a stated tolerance, followed by a written evaluation that uses test results and user comments as evidence.

Estimating material quantities, waste and costs
Fashion and Textiles learners must estimate material quantities and costs from standard fabric widths and calculate costs, sizes and quantities of components. All pathways must minimise waste and make allowances for cutting when marking out.

Paratoi disgyblion
- Blwyddyn 7
- Pupils work out how many 100 mm by 60 mm pieces they can cut from a 300 mm by 200 mm sheet of MDF and sketch the layout that wastes least.
- Blwyddyn 8
- Pupils cost their cushion project from a price list, working out the fabric length needed from a 115 cm wide roll and the total cost of fabric, thread and fastenings.
- Blwyddyn 9
- Pupils estimate, then calculate, the material cost of their product for one unit and for a batch of 20, and work out the percentage of the sheet wasted.

Scale, working drawings and mathematical modelling
Unit 1 requires understanding of working drawings and schedules in commercial product development. In the design project learners may record ideas through formal 2D and 3D drawings, working drawings, exploded diagrams and mathematical modelling.

Paratoi disgyblion
- Blwyddyn 7
- Pupils draw their desk tidy full size on isometric paper with every dimension given in millimetres.
- Blwyddyn 8
- Pupils produce a dimensioned orthographic drawing of their phone stand at a scale of 1:2 and state the scale on the drawing.
- Blwyddyn 9
- Pupils draw a working drawing with a cutting list and marked angles, then scale the design up by 150% to test its proportions on a card model.

Da gwybod
- Unit 1 is typed on screen, not handwritten: "Digital examination: 1 hour 30 minutes" (Summary of assessment, page 4).
- The specification does not mention marks for spelling, punctuation and grammar. The four assessment objectives cover knowledge, application, developing designs and analysing and evaluating, and "The Assessment Pack will include all detailed information relating to assessment." (Assessment, page 43).
- The specification does not say whether a calculator is allowed in the on-screen examination, although Engineering Design learners must "calculate ohms law" (Unit 1, 1.1.9, page 17). Check the Assessment Pack.
- Formula-based calculations are for one pathway only: "This area of study is relevant to learners that have chosen Engineering Design as their pathway." (Unit 1, 1.1(a), page 14). Costing from standard fabric widths sits in Fashion and Textiles (Unit 1, 1.1.18, page 23).
- The design project is "Non-examination assessment: Approximately 40 hours", worth 70% and 100 marks (page 4). AO4, analyse and evaluate, is 20% of the qualification and is assessed only in Unit 2 (page 43).
- Written notes, presentations and mathematical modelling are listed "for example" (Unit 2, 2.1.4, pages 34 to 35), which the specification says "indicates that the specified content is for guidance only" (page 8). No word limits are stated.
Cysylltiadau â chymwysterau eraill
Ohm's law and moments overlap with The Sciences, gear ratios, scale drawing and tolerances with Mathematics and Numeracy, and product analysis and evaluative writing with English Language and Literature, so shared methods and vocabulary would help pupils.
