Developed in collaboration with the International Baccalaureate Organization, Oxford's Course Companions provide extra support for students taking IB Diploma Programme courses. They present a whole-course approach with a wide range of resources, and encourage a deep understanding of each subject by making connections to wider issues and providing opportunites for critical thinking.rnProviding clear and inviting instruction and guidance, this Companion supports students through their Economics course. It includes cross-curricular materials and activities as well as advice and guidance for the portfolio of four commentaries. Examples, features, and case studies drawn from around the world encourage students to develop an international perspective.
