This project taps into the stimulants provided by green environments for facilitating non-formal learning. We will collect and peer review good practices that use parks, nature and woods as green learning environments, and more specific for the target group of children between 8 and 14 years with mental and/or mixed impairments and/or learning disorders. Research suggests this target group takes even more advantage of the green environment for non-formal learning and basic and transversal skill development. The aims of the project are (1) to increase the awareness on the stimulants in nature to facilitate non-formal learning, (2) to collect and review existing practices for non-formal learning in Green Learning Environments with the target group, and (3) developing, testing and disseminating a toolbox.Our multinational, interdisciplinary project team comprises four green partners experienced in education in green areas, and six specialised schools for children with special needs, from Slovenia, the UK and Belgium. Through exchanging and peer reviewing existing practices within the participating organisations and other organisations within and beyond the project countries, we will build a database of and report on good practices for Green Learning Environments (Output O1). Based on this review, we will develop 12 educational materials, methods and tools to be included in the Green Learning Environments Toolbox (Output O2). Three country teams will develop the Toolbox, each team including a green partner and the specialised schools. The materials will be tested in one of the other schools involved in the project, and reviewed by the project team. The joint work on the Good Practices Database & Report and the Green Learning Environments Toolbox will lead to joint capacity building with the project partners. Finally, we will compile a Policy Brief (Output O3), stating the advantages of Green Learning Environments for children in general and our target group more specific. The Policy Brief will also include a brief summary of the project and will introduce the materials and outputs developed.The project will involve 125 children with special needs from 6 schools, and 175 staff members from these schools. We will communicate widely and give a lot of attention towards disseminating the results and tools provided by the project through social media, newsletters, articles in local and specialised press, conferences, mailing lists, ... (expected audience: at least 2000). The project will be closed by a Concluding Seminar, which will be held concurrently in the three countries involved (expected attendance: 55 national participants and 15 international participants each) (Multiplier Events E1, E2 & E3). To stimulate interaction between the 3 concurring seminars, we will set up video-conferencing; online streaming (and recording) the conferences makes it possible to expand the audience to people attending online during, or after the conferences. The Policy Brief will be sent out to relevant local, regional, national and European administrations, authorities, expert networks, umbrella organisations, politicians and policy-makers (over 125 addressees expected). In total we will reach over 2600 people.Apart from the results during the project, we aim at leaving a legacy trough the Green Learning Environments Toolbox, which will be widely promoted and will be freely available online, also after the end of the project, and trough the Policy Brief. We are assured that the project will lead to an increased awareness on the advantages of green areas for formal and non-formal learning. We are assured the Toolbox will stimulate schools and organisations to go outdoors for learning, leading to increased learning outcomes, and eventually to a better inclusion of the target group in society.
