"Robo-Code" is a STEM project which focuses on hand-on activities aiming at the creation of robot-like objects which the learners will put together using cheap, everyday, crafted material, and they will program them to complete a number of simple tasks. To achieve the project goal, Primary School children from Poland and Greece will be guided by Vocational School students from Greece who, through properly-made visual material, will show the young children how to make the different parts of the robot-like object and how to program it using EdScratch. Embedding the flipped classroom approach, the Vocational School students will create and post videos on YouTube listing the materials and featuring the tasks for the Primary School children to imitate. The latter will work in transnational groups with VS students acting as their facilitators. To communicate with the facilitators and their international peers in each group, learners will use TwinSpace FORUMS.
