Certain themes cannot be integrated. It may not prepare students for standardized testing.
Strengths of interdisciplinary
Teaching both perspectives are mutually dependent meaning sometimes you can make connections and sometimes you cannot but both are important.
Teachers need to work together. Talking to each other about what works and what doesn't integrates teachers.
Designing the curriculum
Divide the disciplines and put them in a time framed discipline field base. Separate disciplines.
Parallel disciplines- certain discipline teacher, for example the history teacher, should teach WWII while the english teacher teaches The Diary of Anne Frank.
Multi-disciplinary- not all but two or three disciplines that compliment each other and are taught together.
Interdisciplinary- focuses on a theme of importance combing disciplines in a joint focus.
Integrated day- focuses on the students' questions and interests. Needs careful planning and teamwork
