This presentation examines approaches taken to addressing K-12 education reform in three different countries from the perspective of a consultant and advisor. Specific studies entail the design and co-development of syllabuses, appropriate teacher support materials, assessment and reporting practices, high impact pedagogical strategies and professional learning opportunities; the creation of a global online curriculum resource as part of a blended teaching and learning model; the design and development of a first ever national curriculum with content and standards deployed on a digital curriculum website; and an overhaul of senior secondary courses with content, standards and draft examinations. The learnings from these have implications for successful implementation of educational reform and practice across contexts and include well-managed and staged implementation, sufficient teacher resourcing, comprehensive stakeholder engagement and consultation, capacity building, teacher support, and strategies for co-development and localisation.
