A complete, ready-to-teach unit for OCR GCSE Computer Science topic 2.3, Producing Robust Programs (J277, Paper 2). Six editable PowerPoint lessons, a work booklet, a homework booklet and full answers take pupils from defensive design to writing test plans and debugging real Python programs.

The six lessons

Why Programs Fail: what makes a program robust, how users misuse programs, and defensive design
Authentication and Validation: range, type, length, presence and format checks, validation vs verification, and login systems
Writing Maintainable Code: comments, indentation, meaningful names and subprograms
糖心Vlogting and Errors: iterative and final testing, and syntax, logic and runtime errors
糖心Vlogt Data and 糖心Vlogt Plans: normal, boundary and invalid test data, and writing and completing test plans
Debugging and Refining: tracing, fixing logic errors and refining a program

What鈥檚 included

6 full lessons (editable PowerPoint) with teacher notes: each has a retrieval grid, Do Now, learning objectives, taught content, I do, we do, you do, varied activities, Green, Amber and Red independent practice, a Success Check quiz and a plenary, with answers slides throughout
Work booklet (41 pages) with answers: notes pages, activities and tiered practice for every lesson
Homework booklet (17 pages) with answers: six homeworks and a unit review, also as a PDF
Python practice programs: seven short programs with real bugs for pupils to find, a cinema booking program to test with a test plan, and fixed teacher versions
Varied activities: card sorts, matching, trace tables, bug hunts, test plans to complete and decision cards
