‘Building community across generations through media literacy’ – small grants for intergenerational media literacy learning projects

Closed

Code: 39163 | Programme name: 17855 | Start submission calls: 12/12/2025 | End submission calls: 06/02/2026

The overall objective of this call is to build a sense of community and intergenerational trust through creative projects that promote media literacy, with a focus on people living in rural areas and small to medium towns. This is a pilot programme, with the aim of generating insights and ideas that can be employed in other Member States beyond the pilot period.

The specific objectives are to:

1. Build a sense of community and intergenerational trust – Foster dialogue, solidarity, and collaboration across age groups to reduce isolation, challenge stereotypes, and increase participation in community life. Approaches that encourage active participation are encouraged.
2. Increase media literacy and critical thinking – Equip the target groups with skills to critically navigate digital and traditional media, to be aware of responsible media use, and to recognise online scams and disinformation.
3. Encourage the use of trusted local spaces – Project must take place in a setting within a community where community members feel safe and respected and are comfortable meeting, engaging with each other, and discussing different topics. This may be publicly accessible (e.g. library or community centre), or semi-public (e.g. care home, school) provided that the trusted local space can facilitate the building of trust and social connection among its participants.

Next-generation AI agents are autonomous systems powered by large AI language models (e.g., large language models or large multimodal models), that can plan, utilize tools and perform actions autonomously to achieve specified goals based on high-level instructions.

The large AI model acts as the agent’s “brain,” capable of interpreting instructions, generating plans, and using tools. This capability enables agents to autonomously plan and adapt behaviour in real-time to accomplish complex, multi-step tasks.

AI Agents hold significant promise in numerous applications areas such as data analytics and coding.
