The term "integrated curriculum" has many different, sometimes conflicting, meanings to educators. In this manual, integrated curriculum refers to the materials and pedagogical strategies used by "multidisciplinary" teams of teachers to organize their instruction so that students are encouraged to make meaningful connections across subject areas. English, mathematics, science, social studies, arts, world language, physical education, and career technical teachers can all collaborate to plan and present related lessons that center around a central, career-themed issue or problem. Integrating courses around career-related themes and making those themes relevant to teenagers--while also addressing state-mandated academic and technical content--requires a new model for designing instruction. This practical manual shows teachers how to create exciting and challenging curriculum units for high schools that use this integrated instructional approach. Appendices include: (1) Integrated Curriculum Unit Template; (2) Integrated Curriculum Unit Sample; (3) Student Progress Map Template; (4) Student Progress Map Sample; (5) Project Evaluation Criteria; and (6) Curriculum Integration Action Plan.
