These will aim at testing the MIROR Platform and pedagogical material for pupils/teacher in real didactic practice contexts, and evaluating the suitability of the platform in different organisational learning contexts, that is formal, informal and non formal: for example, within a school of music, in a family setting, community, alone or in a group, with or without teacher, and so on. The protocols will be based on action-research and will involve notably members of the MERYC association. The WP6 is realised in relation to WP2 and WP5, and will produce: 1) experimental data that will be transferred in prototyping implementation by WP2, and 2) specific pedagogical materials for pupils, teachers and music-makers.
