Understanding social, emotional and behavioural development is the foundation for creating a successful learning environment in educational settings. In order to teach and offer differentiated learning, the teacher needs to consider ages and stages of emotional and behaviour development, thus understanding how children learn and why they behave the way they do. Studies have also researched the subject of child development in the frame of developmental milestones and in addition take into consideration, not only individual family circumstances, but also various cultural factors that influence how education is viewed worldwide.
