On Tuesday evening, Arjun, a Grade 9 student, sits at the dining table with three things open: a science worksheet on water filtration, half a paragraph for English about the local vegetable market, and a project brief that asks only, “How can our community become more sustainable?” His mother asks what the project is for. He shrugs and says it is “the IDU”, which explains everything to him and very little to her.
That shrug is common in MYP homes. An MYP interdisciplinary unit, usually called the IDU, asks students to bring two or more subjects together around one real-world question. An MYP interdisciplinary unit is a planned piece of learning where subjects such as science, language and individuals and societies explore a shared global context, and students are assessed against the subject criteria behind those subjects. The most useful thing a parent can do is ask good questions, not supply the answers.
What an MYP interdisciplinary unit actually asks of students
Every unit is built around a global context, a broad theme that gives the learning a purpose beyond the classroom. The MYP uses six of them, and schools choose the context that suits the unit:
- Identities and relationships
- Orientation in space and time
- Personal and cultural expression
- Scientific and technical innovation
- Globalization and sustainability
- Fairness and development
Inside that context, the unit has a statement of inquiry, which links key concepts such as form, change or perspective to the topic. Teachers also use related concepts to sharpen the thinking. For Arjun, the sustainability context meant asking how water is cleaned, who depends on the market, and what a town can change without buying new machines. The subjects were not separate lessons. They were different lenses on the same problem.
How the unit is assessed, and why that matters at home
Students are not marked on whether the project looked impressive. Their work is judged against the subject criteria of each discipline involved, such as investigating, communicating or reflecting, using the descriptors that teachers already use in ordinary lessons. That is why a poster with no evidence of research scores less than a plainer piece that shows clear thinking.
Reflection and Approaches to Learning skills, such as organising time, collaborating and communicating, also shape how the work is planned and judged. A child who is stuck on any of these areas is usually stuck on the process, not the content.
Where students usually get stuck
- Choosing a focus that is too broad, such as “pollution”, instead of a question they can investigate
- Treating each subject as a separate box and never connecting the findings
- Collecting sources without checking whether they are reliable
- Leaving the reflection until the final night
- Working on the product before the research is finished
Practical ways parents can help without doing the work
Helping with an IDU is mostly about structure. The work should still belong to the student, and the teacher should still be able to see that it does.
- Ask for the question in the student’s own words. If they can explain the research question in two sentences, the rest usually follows.
- Make a simple timeline backwards from the due date. Mark when research, drafting and reflection should be finished, then check progress once a week.
- Test the claims. Ask, “How do you know that?” and “Where did you read it?” This builds the source-checking habit that criteria reward.
- Listen to the reflection. Ask what surprised them, what they would change, and what they learned about working in a group.
- Keep a note of what is confusing. Vague worries are hard to act on, but a specific question, such as “How do I cite a government report?”, can be taken to the teacher.
What good support looks like in a small batch
Support is most useful when it happens during the planning stage, not the night before submission. In a small group, a teacher can check each student’s focus question, notice when the subjects are not connecting, and point to the criteria the work needs to meet. At INACADEMICS, our classes run in batches of four to eight, and our subject specialists teach with the published assessment criteria in front of them, so feedback on an IDU sounds like the feedback the school will give.
If your child is in the MYP and finding interdisciplinary work hard to manage, our IB MYP tuition programme covers Grades 8 to 10. Each student receives a short diagnostic and a plan for each subject, with weekly worksheets, monthly mocks and regular updates for parents tracked against that plan.
Frequently Asked Questions
Is the interdisciplinary unit graded separately from my child’s subjects?
Usually not as a separate subject. The unit is assessed against the criteria of the subjects it draws on, so each piece of evidence contributes to the subject judgements. Students should therefore understand which criteria apply to which part of the work, and parents can ask the school for that breakdown.
How much help is too much?
Help that asks questions, checks deadlines and explains a concept is useful. Help that rewrites paragraphs or creates the product is not, because the teacher needs to see the student’s own thinking. If you are unsure, ask your child to talk you through the work. If they can explain it clearly, the help is probably in the right place.
Does INACADEMICS help students with IDU projects?
Yes. Our teachers plan with the student’s focus question and the relevant subject criteria, then check the research and reflection stages as the unit progresses. Parents receive regular updates tracked against the student’s plan, so you know what is on track and what needs attention before the deadline.
