To effectively and efficiently implement blended science and technology education, teachers should be able to find educational resources that suit their need, fit with their curricula, and that can be easily exploited in their classroom. The European Union has supported the FP7 Go-Lab Integrated Project (2012- 2016) and then the H2020 Next-Lab Innovation Action (2017- 2019) to develop and disseminate inquiry learning spaces as open educational resources integrating online labs. This paper presents the technical ecosystem supporting these initiatives and combining loosely-coupled cloud services and platforms. The golabz.eu sharing platform is a repository offering online labs, scaffolding apps, and inquiry learning spaces created by teachers for teachers. The graasp.eu authoring platform is a social media enabling collaborative creation, agile personalization and secure exploitation at school, as well as exchange of best practices between teachers.
