T Level Digital Software Development Year 2: teach 3.1 source reliability through software industry examples, interactive tasks and teacher notes.
This editable 18-slide PowerPoint covers Occupational Specialism 3.1: understanding and evaluating the reliability of different sources of knowledge.
Students explore how developers find technical information, evaluate evidence and justify which sources to use in a software project.
What’s included:
Coverage of search engines, websites, wikis, blogs, academic papers, peers, forums, code comments and repositories.
Clear explanations of reputation, bias, supporting evidence, currency, cross-referencing and triangulation.
Real software examples involving MDN, Flask and the V8 engineering blog.
Short discussions, source-selection questions and a JavaScript code-checking activity.
A worked source evaluation and paired comparison task.
An independent scenario-based exit ticket.
Teacher notes with suggested answers, timings, misconceptions, support prompts and source links.
A teacher guide and specification coverage map.
The presentation uses a consistent, calm colour scheme with readable text and structured cards. Its emphasis is on applying knowledge: students inspect information, consider its limitations and explain decisions rather than simply memorising definitions.
Designed for approximately 65–75 minutes of teaching, with flexibility for discussion. Suitable for classroom delivery, consolidation or revision. Internet access supports the source-comparison activity; summaries are included on the slides.
Supplied as an editable PowerPoint. Activities are embedded within the presentation; a separate worksheet pack is not included.
