<< Objectives >>At the most general level, the objectives of the project are to meet the needs of educators to support learners towards cultivating sustainable behaviours and values. At a more specific level, the objectives are to promote tinkering as a method in education in the field of sustainability. At a concrete level, the objectives are to train a group of educators, in formal and informal settings, to use tinkering to engage learners in projects dealing with issues of sustainability.<< Implementation >>The main activity in the project is the implementation of tinkering in various educational settings, in each participating country. The implementation stretches over 8 months and builds on previous activities which concern both knowledge gathering and training of participants. The implementation will be guided by the Tinkering Toolkit which helps focus the work on sustainability with a clear STEAM relevance.<< Results >>Outcomes take a tangible form as knowledge reports and a Tinkering Toolkit, and an intangible form as training of educators and implementation of tinkering. Concerning the former, results will be national reports mapping the field of potential use and methods and guidelines developed into a Tinkering Toolkit. Concerning the latter, results consist of training for the participants in the project, national training activities for educators and sustained implementation activities in each country.
