Eight Concepts of Curriculum Construction Although a model for curriculum improvement may show us a process, it does not reveal the whole picture. It does not show us, for example, how we go about choosing from competing content, what we do about conflicting philosophies, how we assure articula- tion between levels, how we learn to live with change, how dependent we are upon ef- fective leadership, what incentives motivate people to try out new ideas, how to go about finding the information we need to make intelligent decisions, and how we release human and material resources to do the job.
