A few years ago I spent a great deal of time putting together an interactive package and a book (both called 'Models and Theories in Geography') aimed at those studying or teaching A level or IB geography. The following is a brief list of the models and theories I dealt with in that work, it may help you compile a more complete coverage for your own course. If there are any other models or theories that you feel should be included here please mail me.
