An educational model centred on an approach to solving environmental proble
ms may promote among student teachers the development of cognitive skills a
nd skills that may lead to environmental action. However, the testing of th
is model has not shown that other skills related to this type of problem re
solution have also resulted, specifically, the ability to look critically a
t their own attitudes and behaviours and the ability to analyse the nature
of their interrelations with others. We attribute this to the fact that the
se skills, which are more introspective probably require a more complex lev
el of reasoning in order to develop.
