From September 25-29, 2023, a manual testing training was held as part of the “Vector World” project. The goal of this training was for 20 teachers from partner schools from Croatia, Serbia, Slovenia and Portugal to test the manual that they would apply in class and give their opinion for improvement and changes. The Digital Manual is the final result of the Erasmus+ project “Vector world”, and it was created with the aim of improving the teaching of graphic design.
