Following a structured, multi-phase instructional design model grounded in the DigComp framework and supported by Open Educational Resources (OERs), the course was delivered over three training cycles via a MOODLE-based platform. The research employed pre- and post-course competence tests to assess the course\u2019s impact, as well as post-course surveys with both quantitative and qualitative elements to assess participant experiences.
