Addressing the inclusion of sustainability in the training of teachers is essential if we want to enable the mobilization of capacities necessary to face the existing planetary emergency. The main goal of the present research is to analyse the effectiveness of collaborative work actions and of collective and individual evaluation of teaching guides and educational actions in relation to the inclusion of sustainability in the Master´s Degree in Secondary Education Teaching. Two subjects from Physics and Chemistry specialisation and other two from Biology and Geology specialisation have been analysed. Working groups have been created in order to identify the different sections of the teaching guides with possible links to ESD and Sustainability, highlighting those occasions in which the inclusion of sustainability can be encouraged. As part of this process, teachers from the Master´s Degree will also make proposals of research topics related to ESD could be included in Master's Final Projects. This study is part of a larger research project entitled "(Re) orienting teaching practice towards Sustainability: virtual and face-to-face environments for the training of Secondary Education teachers” with an ultimate goal of catalysing the process of curriculum change towards sustainability
