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.

Sgiliau sy'n defnyddio Mesur

  1. Measuring and marking out within tolerances

    Asesu: Mewn gwaith cwrs (asesiad di-arholiad)

    In every pathway learners must measure and mark out accurately from reference points or datum faces. Engineering Design and Product Design learners must work within specified tolerances, and Fashion and Textiles learners must measure standard seam allowances of 15 mm.

    Rhifedd: Mesur, Y system rif, Cymhwysedd strategol, Cyfathrebu â symbolau

    Paratoi disgyblion

    Blwyddyn 7
    Pupils mark out a pine box side to 120 mm, plus or minus 1 mm, with a steel rule and try square, then check a partner's piece and record whether it is within tolerance.
    Blwyddyn 8
    Pupils mark out an acrylic keyring from a datum edge, measure the finished piece, and record the difference from the drawing in millimetres.
    Blwyddyn 9
    Pupils use vernier callipers to check five cut or turned parts against a tolerance of 0.5 mm, recording the upper and lower limits in a table and rejecting parts outside them.

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.
