The TACCLE3 coding project aims to support teachers in teaching computing to children aged 4-14 by providing resources, in-service training, and a dedicated website. Funded by the European Union's Erasmus+ program, it emphasizes the importance of introducing programming into school curricula to enhance employability and STEM skills. The project, which runs from 2015 to 2017, involves multiple educational institutions across Europe working together to equip teachers with effective coding teaching materials.
