In order to make a dramatic change in the way teachers approach science writing, the authors found it necessary to address both science instruction as a whole and the use of writing during various stages. To guide them in this endeavor and communicate a concrete idea of an ideal foundation for highly effective science writing to teachers, the authors turned to the CORE Model of Instruction. The CORE Model on instruction, which was originally developed as a representation of the manner in which reading and writing can be linked and reinforcing to each other, is described in this article. The CORE Model incorporates four elements: Connect, Organize, Reflect, and Extend.
