"<< Background >>To act on a massive and collective basis in order to achieve the necessary social and ecological transition, the education system must continue its transformation by increasingly integrating education to the environment and to changes in field practices. The goal of our PACTE project (Sharing, Learning, Understanding for the Ecological Transition) is to deploy effective, free and widely accessible educational resources in order to allow school audiences (and not exclusively) to understand and to begin to act individually and collectively against climate change and more generally environmental degradation.According to the survey ""The exercise of the profession of school teachers through the prism of the work context and life courses"", out of the thousands of professionals questioned, barely 1 in 2 declares that they have ""sufficient and appropriate educational means"". According to the School Education Gateway ""Curriculum Redesign"" survey, in 71% of cases ""environmental sustainability"" is considered ""not at all"" to ""moderately"" taught in schools. The purpose of this ""PACTE"" project is to enable the Loire Education League, LEEP and Le Mille e una Notte to contribute to strengthening environmental education and sustainable development actions at school. This reinforcement is in our opinion essential to consolidate the ecological and social transition and overcome the current social and environmental challenges. The survey on ""Climate education"" indicates that ""Lack of training and resources are the main obstacle preventing teachers from including the subject in their lessons"". At the primary level, according to the survey ""The exercise of the profession of school teachers through the prism of work contexts and life courses"", out of the thousands of professionals questioned, barely 1 in 2 declares that they have ""sufficient material. and adapted "".<< Objectives >>To supply key resources to the educational community resources for the educational community, the aim of our project, will allow us to meet the needs of teachers and schools and thus make it possible to achieve environmental education and sustainable development extended to the largest number. By developing this project, we also wish to establish a link between the fields of school and popular education with scientific circles and local expertise in ecological and social transition to which we will testify.<< Implementation >>Through planning over 3 years, we will carry out partnership work with different educational and scientific players to develop 3 major educational resources. Their development will involve research related in particular to a diagnosis of territorial initiatives to be promoted because they stimulate positiv activities, a work of pedagogical construction of educational sequences and supports, graphic work and adaptation to cultural contexts. in our countries, a major testing plan with partner students and teachers, as well as editing of materials to facilitate deployment.This sequence will be accompanied by a permanent work of information on the project and finalize by the massive dissemination of our productions to the educational actors of our countries. Everything will be organized within the framework of an evaluation and continuous dissemination plan.<< Results >>In the end, during this project we will create 180 (60 per country) educational trunks including 6 key topics: Climate, water, biodiversity, responsible consumption and production, health and environment and eco-citizenship (including the social dimensions of the sustainable development objectives of ONU). Each trunk will be made up of our three major productions, which will be thematic animations and educational means for the class, online resources for webinars and / or distance work, as well as thematic educational posters for wide dissemination.During the project we will inform a thousand students and support the work of about thirty teachers. Also, this project will enhance the expertise of our staff and organizations."
