IB MYP Sciences: Course Models and eAssessment Content Scope — Revision Notes

The full syllabus guide confirms schools choose between discrete, modular and integrated course models, but the course model does not decide what the eAssessment examines: its topics span biology, chemistry and physics, and which of them a student’s examination covers is set by the eAssessment option entered, not by the model their school used. These notes cover that structural distinction, alongside the assessment revision notes and investigation skills exam preparation already on the site.

The three course models

• Discrete — biology, chemistry and physics (or other disciplines such as environmental or life sciences) taught as genuinely separate subjects.
• Modular — two or more discrete sciences taught in rotation across the year.
• Integrated — disciplines blended together rather than taught as separate strands.

This is a school-level choice, not a fixed feature of the subject — confirm which model your own school actually uses before assuming a description written for a different structure applies to you.

Why the model matters for revision organisation

A student on a modular timetable organising revision as if their course were fully integrated (or vice versa) risks structuring study time around the wrong unit boundaries — the underlying content overlaps substantially, but how it was sequenced and taught differs by model, which affects how efficiently you can organise a revision timetable around it.

eAssessment scope is set by the option, not the course model

The on-screen examination is available in biology, chemistry, physics and integrated sciences, and the examinations can draw on topics including atomic structure and bonding, cells, cycles, electromagnetism, evolution, interactions between organisms, forces, states and properties of matter, metabolism, organisms, and waves — spanning all three underlying disciplines. Which of those topics your own examination draws on depends on the option you are entered for, not on how your school’s timetable was structured.

Worked example: organising revision across a modular timetable

A student on a modular course studied biology in Term 1, chemistry in Term 2, and physics in Term 3.

Risk:            revising only the most recently taught module
                 (physics) because it feels freshest, assuming
                 earlier modules are "done"
Correct
approach:        build a revision schedule that revisits ALL modules
                 taught across the year that fall within your
                 eAssessment option's scope (for integrated sciences,
                 all three) -- not just the most recent one
Practical step:  create one summary sheet per module taught, reviewed
                 on a rotating basis in the weeks before the
                 examination, rather than a single pass through
                 content in teaching order

Common mistakes

Assuming eAssessment content is limited to whichever single science was taught most recently on a modular timetable. Confusing which course model your own school uses, leading to revision material organised around the wrong unit boundaries. Treating “integrated sciences” content as somehow lighter or less rigorous than discrete-subject content, when the same underlying framework and assessment criteria apply regardless of model.

Quick revision checklist

• Confirm with your teacher which course model (discrete, modular, integrated) your school actually uses.
• Build a revision schedule that revisits every science module within your eAssessment option’s scope, not just the most recent one.
• Check which specific eAssessment option (biology, chemistry, physics, integrated sciences) applies to you.
• Treat all covered disciplines as equally examinable, regardless of teaching sequence.

Why the framework allows this flexibility

The MYP’s key concepts for sciences — change, relationships and systems — and its emphasis on inquiry as the working practice of the subject are deliberately designed to transfer across whichever course model a school chooses. This is why the same investigation-skills task (worth half the eAssessment’s marks) applies identically whether a student’s course was taught as three discrete sciences, a rotating modular sequence, or a fully blended integrated course — the practical skill of designing, running and evaluating an investigation does not depend on how the underlying content was packaged.

Weighting revision time correctly

Because the investigation-skills task (criteria B and C) carries fully half the available marks (50 of 100), fluency in designing, running and evaluating investigations deserves proportionately more revision time than content recall alone. A student who knows the facts across all their taught modules but has not practised formulating a testable hypothesis and interpreting imperfect real data under exam conditions is under-prepared for where most of the marks actually sit, regardless of which course model they were taught under.

Key and related concepts still apply across all models

Regardless of course model, MYP Sciences is organised around the key concepts of change, relationships and systems, explored through related concepts such as energy, movement, transformation and models. These concepts, and the six MYP global contexts, provide a consistent conceptual thread across whatever specific content your school’s model happens to cover — useful to keep in mind when connecting content from different modules or disciplines during revision.

Self-test

1. Name the three course models schools can choose between for MYP Sciences.
2. Is the choice of course model a student-level or school-level decision?
3. Which four eAssessment options does the on-screen examination offer?
4. Why is it risky to revise only the most recently taught module on a modular timetable?
5. Does an integrated sciences course follow a different underlying assessment framework from a discrete one?

Answers: 1. Discrete, modular, integrated. 2. School-level. 3. Biology, chemistry, physics, and integrated sciences. 4. Because the eAssessment can draw on any content within the scope of the option entered, whenever in the year it was taught, not just the most recent module, so neglecting earlier modules leaves genuine content gaps. 5. No — the same four assessment criteria and overall framework apply regardless of course model; only how the content was sequenced and taught differs.
