During the current school year 2014-2015 a National Educational Scenario contest has been conducted under the Institute of Educational Policy (ΙΕΠ) with the title “School gardens and raised beds: production and disposal of agricultural products”, with the support of GreeNet. In the beginning of June 2015, eight (8) school scenarios have been selected, amongst others submitted, applying the evaluation criteria described in the contest announcement document. The schools range from kindergarten to primary and secondary, as well as one lyceum. Ten (10) teachers from these schools were selected to attend the summer school conducted at the Primary Science Laboratory in Rethymno Crete (http://efepereth.wikidot.com), during the period of 21^st-25^th of June 2015

The main objectives of the summer school have been the following:

• to bring together colleagues with relevant interests in school gardens, share educational scenarios and activities conducted during the school year 2014-2015
• to develop and share ideas for further implementation in educational contexts as a small community of practice
• to engage in activities, small project constructions, table and virtual games on gardening etc. that have already been developed and extended in several cases
• to familiarize teachers to open educational resources, repositories and authoring tools available for the development of educational scenarios
• to develop ideas for further implementations in action and forthcoming collaborations in European and national projects

At the beginning of the summer school the teachers were introduced to the history and development of school gardening in Greece and in other contexts, based on evidence from available resources (cf. http://efepereth.wikidot.com/garden-resources).

During the second and third day of the summer school the teachers got involved in several hands-on projects, activities and constructions. We started from the idea of “hot boxes” as it had been developed in the 18^th century, as a basic principle for passive solar constructions, such as greenhouses, solar dehydrators and solar cookers and then we got down to the construction of several such devices (cf. http://efepereth.wikidot.com/solar-cookers and http://efepereth.wikidot.com/solar-dehydrators for example). We also had an introduction to composting and then we simple created decomposition columns out of plastic bottles, whereas we also studied the compost chambers out in the school garden (cf. http://efepereth.wikidot.com/garden-compost). The teachers also got involved in microscope studies linked to the seminal work of Robert Hooke’s Micrographia (1665), with self made microscopes, where they examined specimens from the school garden, such as seeds (thyme, petunia), plants (leaves, flowers, roots etc.), insects (ants, bees, isopods etc.), with commitment, interest and high enthusiasm (cf. http://efepereth.wikidot.com/hipst). Furthermore, the teachers have been introduced to basic principles of biological pest control, as the beneficial action of predators, parasites, pathogens, and competitors in controlling pests and their damage in the garden plants.

During the fourth day of the summer school the teachers were involved in creating educational scenarios with ODS and ISE authoring tools, implementing metadata on their scenarios and practiced uploading them to platforms and repositories. They worked with their laptops and managed to acquire basic skills in these processes, also creating their school repository to use in the coming school year. The teachers were also introduced to “communities of practice” such as the “My school garden” community (http://portal.opendiscoveryspace.eu/community/my-school-garden-o-sholikos-moy-kipos-70514), or groups of special interest, created in social media (e.g. https://www.facebook.com/groups/1587449181539164/).

During the final day of the summer school the teachers presented their work described in the educational scenarios they have implemented in their schools, which are to be uploaded in the community page (http://portal.opendiscoveryspace.eu/community/my-school-garden-o-sholikos-moy-kipos-70514) and in the wiki of the Primary Science Laboratory (cf. http://efepereth.wikidot.com/summer-school-greenet-2015).

Overall, the teachers enjoyed the content, processes and hospitality of the summer school, making it a successful endeavor, as it is documented in the evaluation questionnaires they have filled in and in their concluding remarks.
