Logical Reasoning & Debugging
Computing: Year 5 & 6 National Curriculum, topic 3.1.5
Logical Reasoning & Debugging
Logical reasoning is thinking about the order of steps (the sequence) and the selection rules ('if ... then' and 'repeat until...').
Logical reasoning
- You can run through an algorithm by following all the steps.
- You can run through the steps in an algorithm to check if the algorithm will work.
Debugging
- If your algorithm does not work, you have to debug it.
- Debugging is finding where the problem is and then fixing it.
How to debug an algorithm
- Debugging an algorithm needs patience and computational thinking!
- Computer programmers have programs which help them find where the bugs are.
