“The most important aspects of quality in preschool education are stimulating and supportive interactions between teachers and children and effective use of curricula. Children benefit most when teachers engage in stimulating interactions that support learning and are emotionally supportive. Interactions that help children acquire new knowledge and skills provide input to children, elicit verbal responses and reactions from them, and foster engagement in and enjoyment of learning. Recent evaluations tell us that
effective use of curricula focused on such specific aspects of learning as language and literacy, math, or socio-emotional development provide a substantial boost to children’s learning. ” (Yoshykawa, H. et al., (2013, October). Investing in Our Future: The Evidence Base on Preschool Education.).
