Having looked at the course description, I wonder why Holistische Pedagogiek was not chosen as the title in Dutch. It is true that Holistics usually has a more medical connotation but at least that connotation brings to bear a focus on the individual person in relation to the whole, with the whole being more than the sum of its parts. In contrast, Ecological brings to mind waste products, soil cultivation, "clean" fuel, ozone layers and a host of other considerations which are focussed on the environment but not necessarily on the individual.
