The largest change of the three — from teaching a syllabus to teaching a framework.
IB is inquiry-led with criterion-referenced assessment, and asks the teacher to design units rather than deliver them. Subject knowledge transfers; almost nothing about planning and marking does.
MYP and DP structure, and where an ICSE teacher fits
Unit planning: key concepts, related concepts, global context
Criterion-referenced assessment, and why it is not percentages
Approaches to Learning woven through a unit rather than bolted on
Internal assessment, moderation and the IB's own standards
Theory of Knowledge, the Extended Essay, and what a subject teacher owes them
Academic honesty as taught practice, not a policy document
Subject knowledge transfers. Planning and
marking mostly do not. That is the whole reason this path exists as its own thing
rather than a chapter in an induction pack.
