This longitudinal study (2001-09) of two Hong Kong secondary schools highlights six issues with an integrated arts curriculum: first, integration of knowledge and skills negatively precedes the integration of learners' construction of meaning; second, integration is perceived as challenging the profession's status; third, teachers are unaccustomed to co-teaching; fourth, teachers have little prior experience conceptualizing cross-discipline teaching and learning; fifth, Hong Kong's current systemwide education reform places arts integration as a relatively low priority; and sixth, because integrated arts curriculum implementation is not mandatory, the vagaries of individual school management create a plethora of integration approaches that confound the task of forging a common definition. Remedial recommendations include cascading "seed projects" to broaden teachers' views of integrated arts and teaching, facilitating supportive school timetabling, and sharing integrated learning outcomes in the individual schools.[Copyright of Arts Education Policy Review is the property of Routledge.
