The project “Preventing illiteracy through pedagogical innovation and cooperation with families” led by the GIP FORINVAL Amiens (France) in association with the DSDEN de l'Oise (France) brings together the University of BASILICATA (Italy) around the problem of illiteracy, the USR of Piedmont (Italy) and the School Inspections of KONYA in Turkey and BRAILA in Romania to provide innovative and transferable responses in the countries involved.The objectives were to question the teaching of understanding, to pool effective tools and to reflect on actions that would strengthen collaboration with parents.After a diagnosis of the situation of illiteracy in Europe, the learning activities enabled the work teams to share intellectual outputs: the ROLL (tool based on differentiated instruction) for the DSDEN de l'Oise, a training course for students and teacher trainees on the didactics of understanding for the University of Basilicata, the JIGSAW (tool based on cooperative work) for Turkey, the DICOVOC (based on lexical anticipation) for Romania and an e-book that integrates all these productions for the USR Piedmont. The collaborative work of the partners has enabled the adaptation of these tools to broad audiences ranging from kindergarten to adult education.Indeed, the expertise of the Turin partner in adult education has encouraged the French, Turkish and Italian partners from the south to initiate new actions for this target. In addition, these outputs intended initially for the teaching of the native language have been adapted to the teaching of modern languages, to other disciplines and to allophone audiences. The formation of teams (inter-degrees, multi-categories) was a major asset as it enabled the creation of new local working networks by boosting cooperation between schools and institutions. At the transnational meetings, regulations were made to adjust the actions carried out and organize the calendar so that each return of mobility, training paths were created by each partner and allowed the deployment of intellectual outputs in the territories of the partners. Questionnaires were used to assess the level of satisfaction of trained staff and the effectiveness of the tools deployed; scientific evaluations conducted in France and Italy on control and pilot classes show real progress among students. In terms of impact, the partners observed:-increased abilities in mastering key skills for both students and adults in illiteracy situations-strengthening links within educational communities: teachers, trainers, school heads, inspectors, academic directors-continued collaboration with parents, their representatives and associations-an answer to the training needs of teachers who welcome intellectual outputs in which each student engages and which differ from lecture courses-creation of training pathways that are now integrated into curricula-a positive effect on the class atmosphere-a willingness of partners to continue to collaborate on new projectsThe pandemic has significantly changed the way institutions operate, but the project has been able to meet its commitments thanks to the adaptation of partners: two mobilities have been carried out remotely, as well as three of the multiplier events out of the five. This did not prevent the dissemination of project results at local, regional and international level. The on-line training and tutorial capsules were part of the dissemination activities; they will also ensure the sustainability of the outputs. The website of the project www.erasmus-illettrisme.fr will maintain the link with the school communities of the 5 delegations but above all, offer access to intellectual productions, news, training, articles, and renewed resources. The quality of the collaborative work and the results obtained confirm the determination and willingness of the partners to continue to carry out European projects in order to seek solutions to the decisive challenges of tomorrow.
