The main goal of the multiplier event was to spread the word about new, internationally developed curricula for secondary school programming courses to Croatian institutions outside our project. We showcased the project’s results and the materials we created. The event was split into two parts: a presentation of the project and its outcomes, and some sample object-oriented programming lessons. Participants from our partner school, Srednja škola Ivanec, shared their experiences of implementing the project’s findings in their classrooms. We also had representatives from several Croatian IT companies. In total, 31 people attended in person and 7 joined us online.
