Curriculum integration is a hallmark of middle level education. This approach to education involves blending topics across content areas as a way of studying topics and problems of interest to young adolescents. Approaches to curriculum integration and interdisciplinary curriculum overlap with concepts like democratic education, place-based learning, student agency, and student-designed curriculum. Here, two teacher educators report on a recent initiative in which we co-designed integrated curriculum along with middle level teacher candidates. We drew on place-based instruction and models of collaboration to develop this project. Candidates then developed integrated units appropriate for middle school classrooms.
