One of the defining features of the International Baccalaureate Middle Years Programme (MYP) is its emphasis on interdisciplinary learning — connecting subjects so students can apply knowledge across contexts. Interdisciplinary units (IDUs) encourage inquiry, creativity, and problem-solving by linking multiple subject groups through shared concepts and global contexts.
Designing strong interdisciplinary units requires thoughtful planning, collaboration, and clear alignment with MYP assessment criteria. By using sample structures and reflective design practices, teachers can create rich, authentic learning experiences that engage students and deepen understanding.
Quick Start Checklist
- Identify common key concepts and global contexts between subjects
- Collaborate across departments early in the planning process
- Align learning objectives and ATL skills intentionally
- Incorporate real-world applications and reflection opportunities
- Assess using the official MYP interdisciplinary criteria (A–D)
The Purpose of Interdisciplinary Learning in the MYP
Interdisciplinary learning is more than combining subjects — it’s about enabling students to synthesize knowledge from different disciplines to address complex questions. The MYP framework encourages this integration to develop flexible, critical thinkers who can transfer skills beyond school.
Through IDUs, students:
- Explore big ideas that connect multiple fields
- Develop communication and collaboration skills
- Apply knowledge to real-world challenges
- Reflect on how disciplines complement each other
This approach mirrors the complexity of real-life problems, preparing students for the IB Diploma Programme and future learning.
Sample Interdisciplinary Unit 1: Sustainability and Design
Subjects: Sciences and Design
Key Concept: Systems
Global Context: Globalization and Sustainability
Statement of Inquiry: Human innovation influences environmental systems and our collective responsibility for the planet.
Learning Experiences:
- Research renewable energy technologies and their impact on ecosystems.
- Design a prototype of a sustainable household product.
- Conduct experiments to test efficiency and environmental benefit.
- Present findings through multimedia reports.
ATL Focus: Research and problem-solving skills.
Assessment: Criteria A–D from both subjects, with a shared interdisciplinary reflection on how design thinking supports scientific innovation.
Sample Interdisciplinary Unit 2: Identity Through Literature and History
Subjects: Language and Literature and Individuals and Societies
Key Concept: Culture
Global Context: Identities and Relationships
Statement of Inquiry: Literature and history shape how societies understand identity and belonging.
Learning Experiences:
- Analyze historical documents and literary works from the same era.
- Discuss themes of identity, migration, and conflict.
- Write a reflective essay comparing historical narratives with fictional perspectives.
ATL Focus: Communication, critical thinking, and empathy.
Assessment: Collaborative presentation and comparative analysis graded through interdisciplinary criteria.
Sample Interdisciplinary Unit 3: Mathematics in Motion
Subjects: Mathematics and Physical and Health Education
Key Concept: Relationships
Global Context: Scientific and Technical Innovation
Statement of Inquiry: Mathematical models help us understand movement and improve performance.
Learning Experiences:
- Collect data on sports performance (speed, distance, accuracy).
- Use statistical tools to analyze results.
- Reflect on how mathematical understanding informs training strategies.
ATL Focus: Data analysis, organization, and reflection.
Assessment: Group report and individual reflection linking math applications to physical performance improvement.
Best Practices for Designing Interdisciplinary Units
- Start with concepts, not content. Identify shared conceptual understandings before assigning tasks.
- Plan collaboratively. Schedule joint planning sessions to align timelines and ensure balance.
- Embed reflection. Ask students to reflect on how each subject contributed to their understanding.
- Keep it authentic. Choose real-world problems that spark curiosity and require multiple perspectives.
Schools should document interdisciplinary units in their planners, including reflections for improvement after each implementation.
Frequently Asked Questions
1. How many interdisciplinary units should a school implement each year?
The IB recommends at least one IDU per year. However, many schools incorporate two or more to strengthen collaboration and transdisciplinary understanding.
2. How do teachers manage assessment in interdisciplinary units?
Both subjects assess their criteria separately, and students also receive an interdisciplinary grade using the shared IB criteria. Clear rubrics and joint planning ensure fairness.
3. What are common challenges in IDU planning?
Time coordination and workload alignment are major challenges. Consistent communication, shared documentation, and leadership support make collaboration smoother.
Conclusion
Interdisciplinary units represent the essence of the MYP — connecting learning, encouraging inquiry, and fostering real-world problem-solving. When teachers collaborate intentionally and design around shared concepts and contexts, students gain the ability to think critically across boundaries.
Well-structured interdisciplinary planning not only deepens understanding but also cultivates the curiosity, creativity, and collaboration that define lifelong learners in the IB community.
