Develop and modify code
Lesson details
Learning outcome
I can develop and modify a system to meet the requirements of a design brief.
Key learning points
- Design briefs can be refined using the 4Ws.
- Control systems can be developed and iterated.
Keywords
Design brief - a statement that outlines the requirements of a product
Iterate - process of refining and improving a design
Justify - explain why something is done
Common misconception
Iterations are only needed when a system doesn't work.
Systems are iterated to modify, fix, develop and improve.
Teacher tip
Consider a range of different design briefs your pupils may come up with. Prepare some micro:bit circuits on Tinkercad to demonstrate to the pupils.
Equipment
Computers with access to Tinkercad.

Assessment exit quiz
4 Questions
Q1.When refining a design brief, we can use the 4Ws. Which are part of the 4Ws?
Q2.When making a design decision it is important to it.
Q3.What do we call the process of refining and improving a design?
Q4.Match the stages of this example program to the stages of the systems.
LDR resistance changes depending on the light level
Micro:bit processes resistance and activate the output LEDs if dark
LEDs emit light

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.
