MYP does not believe in teaching subjects in isolation; it encourages students to see the connections between subjects and the real world. Learning through concepts and global contexts promotes interdisciplinary and holistic understanding. At OIS two or more different subject teachers plan a unit together which is known as an interdisciplinary unit. There is at least one interdisciplinary unit at each year level. As students realize that most real world issues require insights gained from a variety of disciplines, they are encouraged to draw on the many different approaches to acquiring knowledge.
