GCSE Digital Technology
Mae disgrifiadau'r TGAU yn Saesneg yn unig, gan eu bod wedi eu cymryd o fanyleb Saesneg CBAC.
This GCSE asks learners to read unseen client briefs, judge online sources, write extended exam answers, and write proposals, justifications, evaluations and marketing copy for a set audience. Its numeracy centres on Unit 2, where 40% of the qualification rests on cleansing a quantitative data set in a spreadsheet, using formulas and statistics to find audience needs and reporting with charts, plus binary, storage unit and compression ratio work in Unit 1. The biggest thing Key Stage 3 should build is confident spreadsheet data handling, with pupils explaining in writing what their numbers show about an audience.

Sgiliau sy'n defnyddio Dealltwriaeth gysyniadol
-
Building spreadsheet formulas and functions
Learners must use spreadsheet formulas at three levels, from basic arithmetic, SUM, AVERAGE, COUNT, MAX, MIN and IF, through nested IFs, VLOOKUP, COUNTIF and SUMIF, to INDEX, MATCH, FILTER and UNIQUE. They must choose the right calculation for the question and check that the output is sensible.
Rhifedd: Cyfrifiad, Cymhwysedd strategol, Rhuglder, Dealltwriaeth gysyniadol, Rhesymu rhesymegol
Paratoi disgyblion
- Blwyddyn 7
- Pupils total the costs of a class trip to Dare Valley Country Park in a spreadsheet, once with a calculator and once with =SUM, and explain why both answers match.
- Blwyddyn 8
- Pupils use AVERAGE, MAX, MIN and COUNT on a table of their own typing test scores, then write the formula they used beside each answer.
- Blwyddyn 9
- Pupils use IF and COUNTIF to flag and count school club members who have paid, and check one result by hand before trusting the column.

Binary, storage units and compression ratios
In the Unit 1 examination learners must relate binary data to storage units, explain how sample rate, bit depth, colour depth and resolution affect file size, and calculate compression ratios and changes in file size.
Rhifedd: Cyfrifiad, Y system rif, Perthnasoedd yn y system rif, Cyfathrebu â symbolau, Dealltwriaeth gysyniadol
Paratoi disgyblion
- Blwyddyn 7
- Pupils convert their names into binary using an ASCII table and count how many bits and bytes each name needs.
- Blwyddyn 8
- Pupils order file sizes given in bytes, kilobytes, megabytes and gigabytes and work out how many 4 MB photos fit on a 64 GB phone.
- Blwyddyn 9
- Pupils save the same photo as PNG and as JPEG, record both file sizes, and calculate the compression ratio and the percentage saved.

Da gwybod
- Unit 1 is an on-screen examination, so extended answers are typed: "Assessment type: Digital-only examination" (page 10).
- No marks for spelling, punctuation and grammar or accuracy of language are stated anywhere in the specification; detail is deferred to the Assessment Pack: "The Assessment Pack will include all detailed information relating to assessment." (page 35).
- The specification does not say whether a calculator may be used in the Unit 1 examination; compression ratio calculations (page 11) mean centres should check the Assessment Pack.
- Unit 2 NEA is 20 hours and Unit 3 NEA is 10 hours, on a client brief set by WJEC each year: "The client brief will change annually, the tasks and mark scheme will remain the same." (page 36).
- Research is done with internet access outside the timed NEA: "This research time does not form part of their non-examination assessment time" (page 36).
- Audience-focused planning and evaluation carry most weight: AO3 (identify audience needs and plan) is 20% and AO4 (develop, test and evaluate) is 35% of the qualification (page 35).
Cysylltiadau â TGAU eraill
Appendix C marks Listening, Reading, Speaking and Writing in all three units, and the data analysis in Unit 2 draws directly on Mathematics statistics work, so shared vocabulary for averages, range and outliers with the Mathematics department will help pupils.
