Debugging movement
Lesson details
Learning outcome
I can fix the bugs that I find in a program.
Key learning points
- A program can be tested against a design.
- A piece of code can be matched to an outcome.
- A bug is an error in the coding of the program.
- Debugging is finding and fixing these errors in a program.
Keywords
Bug - an error or mistake in code that stops it from working properly or as expected
Debug - finding and fixing errors in a program
Common misconception
Only new programmers will have bugs in their programs.
Every programmer will need to correct errors and debug their code. Part of the process of programming is correcting mistakes made as you go along. Regluarly test your program does what it needs to as you go along.
Teacher tip
You will need to be familiar with the term �debug� and the process of �debugging�. A bug is an error in the design or the coding of the program, and the process of debugging is finding and fixing these errors. Pupils benefit from knowing that teachers will produce programs that have bugs as well.
Equipment
Pupils will need access to a device with block-based programming software. Examples in this lesson use Scratch https://oak.link/scratch

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
