The purpose of this review is to establish what research is available on the effect of modes of travel on children's mental health and cognitive and social development, and the potential for further research. This systematic review was published by EPPI-Centre in 2001 .Systematic reviews aim to find as much as possible of the research relevant to the particular research questions, and use explicit methods to identify what can reliably be said on the basis of these studies.
The policy framework for citizenship education identifies three broad educational aims: the moral and social development of students, political literacy and community involvement. The review aims to inform the way in which citizenship education is implemented in schools, particularly in relation to curriculum content, pedagogy, leadership and management, school ethos and community relations. This systematic review was published by EPPI-Centre in 2004.
