Algorithmic Thinking: GCSE Computer Science Definition

What is algorithmic thinking?

In GCSE Computer Science, algorithmic thinking is defined as the process of creating step-by-step instructions to solve a problem. This approach involves breaking down the problem into smaller parts (decomposition) and focusing on essential details (abstraction). By identifying each step, you can create a clear set of rules, called an algorithm, to reach a solution.

Think of a recipe as an algorithm for cooking a dish. It provides a step-by-step guide with precise measurements and instructions:

• Decomposition: The recipe breaks down the cooking process into smaller tasks, like chopping vegetables, preparing the sauce, and baking.

• Abstraction: The recipe focuses on essential details like ingredients and cooking times, not on the brand of your oven or the colour of your chopping board.

• Logic and Sequencing: You need to follow the instructions in the correct order. Adding ingredients at the wrong time or changing the baking temperature can ruin the dish.

If you follow the recipe precisely, you should achieve the desired outcome – a delicious meal!
