Planning an On-screen History Enquiry
DCF: Producing → Sourcing, searching and planning digital content
Pupils work through the five enquiry stages of an on-screen historical enquiry using printed practice screens on the Great Strike of Penrhyn, 1900 to 1903: a hypothesis and a 3-hour time plan, a provenance grid for two sources and two interpretations, a paragraph plan with item codes and on-screen working habits, one developed paragraph, and a critical reflection. Practises the method of GCSE History Unit 2: An in-depth study on European and/or World history, which is completed on WJEC's e-assessment platform. Penrhyn is not a Unit 2 option and three of the four items are clearly marked as invented, so this is practice only, not NEA work.
Resources required
- Pupil worksheet: Planning an On-screen History Enquiry
- Stimulus: The Great Strike of Penrhyn, practice enquiry screens (question, narrative, timeline and four items)
- Worked example: hypothesis, time plan, item grid, paragraph plan, model paragraph and reflection

Comparing Broadband Speeds with Box Plots
DCF: Data and computational thinking → Data and information literacy
GCSE Mathematics and Numeracy Unit 3: Calculator-allowed, Higher tier statistics: cumulative frequency tables and diagrams (4.2.18), box-and-whisker diagrams to compare distributions (4.2.19), and testing a hypothesis while taking account of the limitations of the data (4.1.2, 4.1.4, 4.2.23). Pupils use an invented community council survey of download speeds in two Welsh villages to build a cumulative frequency table and curve, estimate the median, quartiles and interquartile range, and draw a box plot beside the one given for the other village. They compare the villages with one average and one spread, test the councillor's hypothesis and a resident's claim against Ofcom's superfast and Universal Service Obligation speeds, judge the reliability of a self-selected, one-evening, mixed Wi-Fi and cable sample, and modify the conclusion when cable-only medians halve the gap.

Checking a Software Lead Sheet
DCF: Producing → Evaluating and improving digital content
GCSE Music Unit 3: Appraising, content 1.3.4: how music is notated and captured. An invented composer recorded a Welsh jig into a DAW and let notation software turn it into a lead sheet. Pupils check the software's output against the MIDI data (note numbers, timings, velocities and a chord track) and the composer's notes, and find five errors: 3/4 instead of 6/8, the anacrusis counted as bar 1, a quantise error, a note spelt D flat instead of C sharp, and A instead of A7. They answer exam-style questions on the corrected tune (compound duple time, roman numerals, cadences, intervals), rewrite two bars, and justify their changes to the composer with the settings to use next time.

Pupils find six honesty problems in an invented pupil's draft on the right to education, from copied charity text and patchwriting to a chatbot's unchecked statistic and a misattributed Bible verse. They write Harvard references for five sources, decide which words, photos and slogans can be reused under copyright, a Creative Commons licence or fair dealing, and rewrite the paragraph in their own words with citations, a Muslim teaching, a humanist view and a judgement. Practice with invented charities, not NEA work.
