OCR GCSE Computer Science – Algorithms & Programming Foundations (KS4)

This resource supports KS4 OCR GCSE Computer Science students by introducing the core foundations of algorithms and programming. It covers key concepts including computational thinking (abstraction, decomposition, and algorithmic thinking), flowcharts and standard symbols, and the use of pseudocode and OCR exam reference language.

Students explore searching algorithms (linear and binary search) and sorting algorithms (bubble sort and insertion sort), with clear explanations, real-world examples, and comparisons of efficiency. The unit also develops understanding of syntax and logic errors, helping students identify, explain, and correct common programming mistakes.
