IB Env. Systems & Socs


Introduction: Each WRL data set was linked to the appropriate part of the IB ES framework which we thought could be a relevant place in which to use a particular case study.  The IB ES course codes were then noted and linked to the reference code for WRL.  Whilst some links are more directly applicable to the data set than others, they might be a valuable example to use and include in a scheme of work. We also realise that some of our matching may be more ‘on target’ than others (I suppose you can only do this accurately if you actually teach it!) so we welcome any feedback from teachers and how they have or might use this resource. Click on the WRL dataset module codes in the table below for an overview of the relevant case study.
