Scientific research shows that:
it is easier for a child to become bi/plurilingual when all their languages are valued and when making connections between languages is encouraged;
it is important that parents keep using their family language(s) with their children and that teachers use family languages to help children establish connections between the language(s) of their environment;
it is easier for children to engage in the languages that are taught at school when their own languages are recognised, because these languages are practised in the family environment and by the children;
valuing children's different languages and cultural backgrounds boosts the self-confidence and self-esteem that are necessary for educational and professional success;
parents' participation in school activities establishes a relationship of mutual confidence between schools and families, and helps children to dedicate themselves to their schooling.
