The eTwinning Code4Kids project is an international collaborative initiative involving students and teachers from different countries to promote the teaching of coding to children. The project focuses on the use of block-based programming tools to facilitate the learning of basic programming concepts, using platforms such as Arduino, Micro Bit and Lego NXT, among other educational devices. The main aims of the project: To teach programming in an accessible way, using block tools that make the process more intuitive for children. To develop computational thinking, problem solving and creativity through the construction of practical, interactive projects. To use educational technology such as Arduino and Micro Bit boards and Lego NXT robots to bring programming concepts to life and allow students to program physical devices. Project activities: Programming challenges where students work together to program devices such as the Arduino and Micro Bit. Robot creation with Lego NXT, allowing students to create interactive and dynamic robotics projects. Workshops and tutorials to learn how to use different block-based programming platforms and languages such as PictoBlox or MakeCode. Exploring internet safety, where students learn about safe online practices and the importance of digital privacy. Intercultural engagement: Sharing cultural experiences: As well as learning to code, students have the opportunity to learn more about the participating countries, promoting intercultural understanding. Each country shares information about its culture, traditions and history, enriching the overall experience of the project. Ultimately, Code4Kids not only helps students develop basic technological skills, but also fosters international collaboration, creativity and digital awareness.
