In sharing their excitement over this "real treat, real privilege," the teachers invited the children to find out more about playgrounds and, in particular, their new…

Advances in statistics provide new methods for analyzing practice data. These advances include person-centered methods (PCMs) that identify subgroups of research participants with similar characteristics. PCMs derive from a frame of reference that is similar to the risk factor perspective in practice. In practice, the delivery of services is often…

This preliminary study investigates the current situation of school library support of K-12 health education in China. A survey of 42 school librarians and 115 K-12 teachers from selected schools was conducted to find out their views about school library's role in school health education and their current practice of library use in health…
