In the age of standardized testing, science and social studies are not given the same priority as mathematics and reading in the curriculum of United States schools. High stakes testing is viewed as having heavily biased schools toward teaching tested subjects and away from less frequently tested subjects. This paper is premised on the notion that all subjects are important and none should be neglected; and the general education classroom can be best described as a place for learning with inclusion as the focus. Essential is a model for integrating reading, science, and social studies to enhance inquiry, problem-solving, interest, critical thinking skills, and learning. To meet the standards of inclusion teachers need a model that helps to integrate the content standards, incorporates backward design philosophy, gives a standard format for lesson framework, and allows for differentiated instruction and flexible grouping to teach via inclusion of using taxonomies for adapted learning. Thus, the authors present and discuss the BDIM (Bogan Differentiated Instruction Model) which combines major teaching concepts to develop interdisciplinary teaching. This model addresses the concept of adding differentiated instruction to curriculum integration. In conclusion, a framework that ensures that the lesson objectives and essential questions are interrelated is presented. (Contains 1 figure.)
