Evaluation and modifications
Lesson details
Learning outcome
I can identify modifications informed by evaluation.
Key learning points
- Evaluations are judgments based on the findings of testing.
- Evaluation is required throughout the iterative journey to ensure successful design decisions.
- Evaluation after testing in school informs modifications.
- Successful modifications are justified and originate from evaluations.
Keywords
Evaluation - judgements based on testing findings
Design requirements - something which is needed or wanted to make a product successful
Design decisions - a deliberate choice to meet a requirement or solve a problem
Modifications - making changes or adjustments to improve
Common misconception
Modifications are often quickly generated by the student's personal opinions, rather than their evaluations.
Modifications should be informed from thorough testing and evaluation against design requirements with feedback from the primary user/stakeholders/experts.
Teacher tip
Encourage students to look to their testing and their evaluation to inform their modifications before they think of any themselves!

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.
