After the training program (O3) was completed, participating secondary school in-service teachers from each partner school formed interdisciplinary groups. Together, they planned, designed, and developed educational scenarios for the STEAM curriculum. These scenarios were formulated based on the methodological guidelines outlined in O1 and incorporated the prototype games produced through the ImTech43D project (O4).

The educational scenarios they crafted weren’t just standard lesson plans corresponding to a brief teaching interval (1-2 teaching hours). Instead, they were comprehensive descriptions of all the educational activities that took place, highlighting how they were backed and executed through contemporary pedagogical theories. This was done after considering possible educational challenges that might emerge. Each scenario spanned multiple teaching hours and included a sequence of educational activities.
