In this unit pupils will reflect and build upon designing and making principles to which they have been introduced previously. this will be assessed in the Non-Examined Assessment

Lesson Summary

You will learn to identify modifications informed by evaluation.

Key Notes

  • Evaluations are judgments based on the findings of testing.
  • Evaluation is required throughout the iterative journey to ensure successful design decisions.
