Medium-fidelity prototyping
Lesson details
Learning outcome
I can develop a more functional prototype that integrates usability and inclusivity.
Key learning points
- Medium-fidelity prototypes are more functional and refined.
- Material choice allows prototypes to be tested for ergonomics, accessibility and usability, which improves inclusivity.
Keywords
Medium-fidelity - a prototype that shows what a design will roughly look and work like, but isn’t fully finished or interactive yet
Ergonomics - the interaction (comfort and fit) between people and the products they use
Usability - how easy and comfortable something is to use
Common misconception
Medium-fidelity prototypes are just “tidier” versions of low-fidelity ones.
Medium-fidelity is not about neatness - it’s about using stronger materials and semi-functional builds to test ergonomics and usability.
Teacher tip
Contrast low-, medium-, and high-fidelity prototypes with examples (sketch > card model > semi-functional prototype > polished model).
Equipment
A range of materials suitable for medium-fidelity prototyping, e.g. plywood/MDF/pine, acrylic/HIPS/PP, calico fabric/foam, breadboards/Micro:Bits/electronic components, fastening components, etc.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
