In this document we are suggesting that the specialist subjectcentered curriculum needs to be balanced by an approach that gives priority to every child learning the fundamental strategies of thinking and problemsolving. We believe this necessitates an explicit thrust as a core area of the educational development of every child through the methodologies and techniques we have defined as an interdisciplinary approach.ampampnbsp The interdisciplinary nature of thinking is recognized by the inventor as well as the designer as a frame of mind. For schools to develop this frame of mind in students requires a truly interdisciplinary approach to learning that complements the traditional subjectbased intradisciplinary curriculum.
