The strongest Criterion D answers do one thing well: they pick a single impact, follow it to the people it affects, and then weigh the evidence for and against. A student who lists three benefits and two drawbacks of a technology has described it. A student who traces how one decision changed one community, and explains why it is still argued over, has evaluated it. That shift from listing to judging is where many students gain or lose ground.
Put simply, Criterion D asks for reflection rather than recitation. Choose one impact, name who it touches, use credible evidence, and finish with a judgement you can defend. Everything below builds on that idea.
Start with one impact and follow it through
Broad essays about 'the impact of science on society' tend to float. Narrow your focus. Antibiotic resistance, the shift to renewable energy, or the use of GPS data in farming each give you a clear chain of cause and effect that you can trace step by step.
Once you have your impact, map the chain. What was the scientific development? Who adopted it, and how did their behaviour change? What happened next, and was it intended? This sequence becomes the spine of your response and keeps you from drifting into generalities.
Name the people on each side of the issue
Impacts are rarely felt evenly. A new water-testing method might help regulators and frustrate small local operators. A gene-editing crop might reassure one group of farmers and worry another. When you name these stakeholders, your evaluation becomes concrete and your reasoning becomes easier to check.
- Who benefits most from this impact, and why?
- Who bears the costs, and are those costs short-term or long-term?
- Whose voice is missing from the usual account?
Let the command terms set your paragraph plan
The MYP command terms are a quiet instruction manual. 'Describe' asks for facts. 'Discuss' asks you to consider several views. 'Evaluate' asks you to judge how well something works or how important it is. Before you write, check which verb the task uses and let it shape the paragraph.
A dependable structure for most responses looks like this:
- A clear claim about the impact, stated in one sentence.
- Specific evidence, such as a figure, study or documented case.
- A counter-point or limitation that a sceptical reader would raise.
- A judgement that answers the question, with a reason for it.
Choosing evidence you can actually defend
Examiners look for sources that are relevant, reasonably current and clearly connected to your claim. A report from a government body, a peer-reviewed review or a well-documented case study all serve well. Note what each source cannot tell you. Acknowledging a limitation usually strengthens an evaluation rather than weakening it.
Avoid vague phrases like 'scientists say' or 'many people think'. Replace them with the specific finding, who produced it and what it measured.
How INACADEMICS helps students apply this in practice
In our experience, Criterion D improves fastest when a student gets feedback on reasoning, not only on structure. Our teachers, who work with the MYP rubrics for Criteria A to D and the command terms, review drafts against the descriptors so that a student can see exactly where a judgement is strong and where it needs one more reason. Batches are kept to four to eight students, which gives each learner room to talk through an argument before writing it.
Each enrolment begins with a short diagnostic and a per-subject plan. Weekly worksheets give regular practice, monthly mocks show how Criterion D answers hold up under timed conditions, and parent updates track progress against that plan. If you are looking at our IB MYP tuition programme for Grades 8 to 10, this is the kind of support you can expect.
Frequently Asked Questions
Do I need a famous scientific invention for Criterion D?
No. Strong responses often come from everyday science, such as water treatment, food preservation or local energy choices. What matters is that you can describe the chain from the scientific development to its effect on people, and then evaluate it with evidence.
How does INACADEMICS support Criterion D writing?
Our teachers align feedback to the MYP rubrics and command terms, so students know what a judgement needs to show. Small batches of four to eight students allow regular discussion, and monthly mocks let students practise evaluation under timed conditions before the real assessment.
How can parents follow progress on Criterion D?
Parents receive regular updates that track progress against the plan agreed at enrolment. These updates note which criteria are improving and where a student needs more practice, so you can support revision at home with specific goals rather than general encouragement.
Criterion D rewards focus, evidence and honest judgement. Pick one impact, name the people affected, and never finish without a reasoned conclusion.
