The purpose of OPENING DOORS is to co-develop an interdisciplinary, intersectoral, & international educational offering for post-graduate researchers. Our goal is to shape more innovative, socially aware, integrative and employable research graduates, ready to meet the challenges of the future. This will be accomplished through a challenge-based, open online educational course on open science. The focus of the course is on cultivating valued skills that can contribute meaningfully to the quadruple-helix model of open innovation. This model recognises four major actors in the innovation system: the scientific enterprise, policy, industry, and society. The Covid-19 pandemic has transformed technology-enabled university teaching overnight. An adaptation process that often takes years has been greatly accelerated, disrupting many cultural barriers to using digital learning environments. The OPENING DOORS virtual learning environment will be underpinned by connectivism as the pedagogical approach. Connectivism reflects the networked innovation environments of the future. The specific objectives of OPENING DOORS are to: 1) identify the graduate skills that are valued in open innovation systems through interviews with employers, PhD graduates and educators in those systems 2) co-design an educational course for PhD and postdoctoral researchers in collaboration with industry, government, community, university stakeholders including PhD students, that uses real-world challenges as the basis of collaborative learning opportunities 3) enable students to manage interdisciplinary, intersectoral and international connectivity through an open, online learning environment; reflexivity, interdisciplinary team communication processes, intercultural sensitivity, digital skills and career development will underpin the learning process This work is vital in an era where open science practices are becoming the currency in many intersectoral innovation networks
