Curriculum integration is a tenet of middle level education. "This We Believe," the position paper of the Association for Middle Level Education, advocates for curriculum that is exploratory, relevant, integrative, and meaningful for young adolescents. Teachers can integrate curriculum across content areas by anchoring units of study in issues and themes that are determined along with students. Researchers have studied curriculum integration in different capacities, and further research can continue to explore the impact of this approach to curriculum.
