The staff training event took place at the Gymnasium am Rotenbühl, Saarbrücken, Germany. Two teachers from each participating school and six teachers from the host school took part. First, the teachers got to know each other and presented their schools as well as their roles within the schools and outlined their school system/curriculums with regard to STEM subjects, languages and ICT in order to make sure that the project started on a common ground. With this, we were able to clarify the project’s aims and processes and adapt the project calendar to new developments that have taken place since the project application. Furthermore, especially the new participants learned how to insert the mobilities into the mobility tool.
In the first place, this first staff training event lay the foundations for the entire project, i.e. the platform to work on the project collaboratively, the webinar software, evaluation tools, etc.
A workshop about the learning management system MOODLE carried out by a teacher trainer from Saarbrücken showed the participants the various opportunities of a learning management system, i.e. how a MOODLE course can help to facilitate communication between students/teachers and teachers/students of the participating schools, how communication can be organized (messages or forum discussion), how documents, videos, pictures can be shared, how evaluations can be carried out, how webinars can be scheduled via Moodle, how surveys can be created, etc. The participants were able to set up the basic structure of the Moodle course for the project within the Moodle platform of the Gymnasium am Rotenbühl and practice to create the different content possibilities that are useful for the project, e.g.the survey, providing and exchanging documents, working on the document at the same time from different places, asking for feedback, etc.
The second workshop phase was about how to carry out webinars efficiently. For this workshop, we used the software Adobe connect. The license for Adobe connect was purchased by the Gymnasium am Rotenbühl with the project management grant. This workshop included how to set up a webinar with scheduling the time, inviting participants, basic webinar rules for the participants, how to activate and deactivate microphones and cameras, how to share documents and desktops within the webinar, how to use the chat within the webinar, and how to use the white board collaboratively. The teachers carried out a webinar to test all the different activities.
In another workshop, the Erasmus plus counsellor in the German federal state Saarland, Paul Grannec, introduced etwinning and the twin space to all the participating teachers. Although the schools were mostly used to work in projects such as Erasmus+ projects, etwinning and the twin space has never been used by the schools to carry out the projects. Paul Grannec showed us the different possibilities that etwinning and the twin space provides us with, for example sharing and working on documents, saving documents such as curriculums, schedules etc., using pictures to document what we did during the meetings, carrying out surveys and asking for feedback, inserting external online tools, publishing a project page for the online community, using this platform without breaching data security of the students or teachers, carrying out webinars within etwinning. Thus, we decided together to use etwinning instead of Moodle for the project as the features were even easier to use and more effective than the features in Moodle. In retrospect this was the best decision we could take as the Moodle platform of the Gymnasium am Rotenbühl was deactivated in March 2020. 
The participants learnt how to evaluate workshops as they evaluated the different workshops taking place in Saarbrücken. Different forms of evaluations were used, for example spiderweb evaluations, surveys, fever charts, etc.

The participants benefited from this training session in multiple ways. The teachers new to the Erasmus plus program learned how to manage the Erasmus plus project in their schools and administer them with the help of the online tools. All participants improved test skills of how to manage a project with the help of the twinning and by working co-operatively together with other schools. They learned how to structure learning events on a learning management platform which they can also use in their classrooms. Furthermore, they learnt how to use webinars not only in order to communicate with teachers and students abroad, but also to exchange knowledge and skills via video conferences. This came in especially handy as they could use these experiences with the software such as Adobe connect in the times of the Corona/Covid 19 pandemic. They will also be able to use webinars during their classes in the future and improve the exchange with schools from other countries or in order to invite experts that are not able to come to school physically. Apart from that, the teachers improve the language and in the intercultural communication skills during the training sessions as I work in a transnational environment with five or even seven languages and seven different cultures by talking about a different school systems, they become aware of similarities and differences and about the present state of digitalisation in the participating schools.
