Publisher's description: Offering a new perspective on developing curriculum and instruction, the parallel curriculum model is meant for use in both heterogeneous and homogeneous classroom settings. Whether students are working at a basic level of skill and understanding or at the highest ability ready for more complex learning, teachers can use this model with confidence. The parallel curriculum model offers four parallel approaches to curriculum development to ensure rich curriculum for all learners, and illustrates ascending intellectual demand as a means of extending the intensity of challenge as students develop along a continuum toward expertise in learning. Clearly, education benefits from a variety of models from which teachers and schools can select to most appropriately address the learning needs of students. Here, the authors illustrate how use of the parallels shape curriculum for students--and the ongoing professional growth of educators themselves.
