Criterion D — Reflecting on the impacts of science — is the criterion science teachers most often under-assess. It asks students to write essay-style answers in a practical subject: evaluate how science affects people, societies and the environment, and back it up with reasoning and sources. Many students treat it as an opinion piece. It isn't — and the difference is markable. In this session we'll cover: - What Criterion D rewards, strand by strand — and what "discuss and evaluate" means at levels 7–8 versus "outline" at levels 1–2 - How to pick impact topics that give students something real to evaluate (not just "science is good and bad") - The structure of a top-level response: claim, consequence, counter-view, judgement - How scientific language and referencing are assessed inside this criterion - Marked examples of student-style responses across the achievement levels For MYP Sciences teachers of all year levels. Pairs well with our Criterion B session — together they cover the two criteria teachers ask about most.
