According to the IB

According to the IB:

Concepts are big ideas that have relevance within specific disciplines and across subject areas. Students use concepts as a vehicle to inquire into issues and ideas of personal, local and global significance and examine knowledge holistically.

• Concept-based inquiry is a powerful vehicle for learning that promotes meaning and understanding, and challenges students to engage with significant ideas

• Concepts are powerful, broad and abstract organizing ideas that may be transdisciplinary or subject-based.

• Concepts help to build understandings across, between and beyond subjects.

• Key concepts provide a lens for conceptual understandings within a transdisciplinary unit of inquiry; related concepts provide a lens for conceptual understandings within a specific subject.
