This document covers the information and instructions that educators need to use the MILEAGE tools and provide the MILEAGE learning program to the target group. Educators must know what is relevant to seniors and how to use the proposed tools. They also need a clear vision of the challenges seniors face today and guidance on supporting them to overcome both barriers and risks. The handbook offers suggestions to make sure younger seniors are motivated to support older seniors and that educators are aware of how to foster good peer-learning opportunities and socialization possibilities. Educators and senior peers can use the handbook to get inspiration for adapting their communication style and pedagogy.
