We have managed to train as many as 1,500 teachers of early childhood education as part of the “Code to the Future” project carried out in eleven regions in the country, despite the lack of funding and the coronavirus pandemic. Everyone uses our training platform available at https://polanski.edu.pl. As part of this project, teachers learn how to teach children to program in grades I-III using ScratchJr and Lego WeDo 2.0 blocks. Both technologies are very friendly and do not require IT education. And they allow you to quickly learn the basics of learning programming and make lessons much more attractive.
