The project “Interventions for Improving Language Skills in Three to Six-Year-Old Children in Day-Care Facilities in German-Speaking Countries: A Systematic Review ” aimed to give an overview over which interventions exist for improving language skills in the children’s first language and national language of instruction in German-speaking countries. Moreover, it was reviewed the current knowledge regarding which language intervention approaches will (or can) deliver which effects in the context of specific institutional and individual conditions.

Language competencies are among the prerequisites for individual success in education. In Germany, children with delays in language development or children with an immigrant background whose native tongue is not the language of instruction bear a significantly higher risk of experiencing poorer school and vocational progress than might be expected given their general cognitive skills. Consequently, unrestrained participation in society is endangered owing to delays in the cognitive, emotional and social development of the children concerned.

Policy makers in Germany have recognised that society needs to foster educationally relevant language competencies even in very young children, a need that has recently gained in urgency by the arrival and likely stay of large groups of refugees from war zones in Asia and Africa. As yet, it remains an open question, however, how to best proceed: Which language intervention approaches will (or can) deliver which effects in the context of specific institutional and individual conditions?

The proposed project aimed to remedy the situation and to systematically document and integrate the available information about successfully tried and tested language interventions.
