Open educational resources or platforms Challenges of the Public University in a context of growing technological mediation

The word platform, widely used in everyday speech to name all types of online services, has, however, a precise definition: it is a service (generally commercial) that collects and processes data from its users within the framework of competitive dynamics. Its widespread use with a broader meaning hides the differences between public and private infrastructure, between resources and exploitations. In the case of educational platforms, making these differences invisible contributes to the processes of commodification and privatization of education. The outbreak of the COVID-19 pandemic made it necessary to cling to any tool that would allow educational continuity to be guaranteed, once the period of restrictions has been overcome and face-to-face education is back, it is necessary to recover a critical approach that preserves autonomy, promotes significant uses of technology, and secures the rights of teachers and students.
