European Day of Languages 2022
Mon, Nov 7, 2022 12:00 AM

The students  that participate in the eTwinning project "CODE RACE @SDGs" participate with their partners in the European Day of Languages 2022. They follow a shared lesson plan and each student creates a project in scratch, where phrases-concepts of the project are translated in European Languages. They use the translate extension and the text to speech extension in Scratch and they discover how their commands work.

This is one of the very first projects the students create in scratch, so one of the goals is for them to get familiar with the use of the environment, to understand and use two Events commands and realize the difference in the user's interaction, to use backdrops, to modify the operands in the commands, to find the errors and debug their projects

All students' productions are gathered in a shared studio https://scratch.mit.edu/studios/32232807 and also in a padlet https://padlet.com/etwpetroupoli/coderaceedl
