Many educational reforms have as one of their key goals the promotion of scientific literacy and they encourage engagement with science in the news as one aspect of this. The research indicates teachers using the news do so for a variety of reasons, sometimes with tangential links to the promotion of scientific literacy. Demonstrating the relevance of science to the world beyond the classroom or making links to socio-scientific issues and promoting discussion on ethical dilemmas are all seen as potential reasons for engaging with science–related news. However, media related issues are often not addressed. Increasingly the need for a more comprehensive approach, including, for example, teaching about media awareness in the context of science reporting, is highlighted. The steady growth of literature describing the use of science-related news along with research studies charting students’ responses to science news media has stimulated discussion and study of pedagogical issues and prompted this review. Key literature relevant to students’ engagement with science-related news reports has been contextualised and reviewed to identify core issues for teachers, teacher educators and curriculum planners. These are listed under the headings of curriculum, pedagogy and assessment, the implications are considered and directions for further research suggested.

In many environmental valuation applications standard sample sizes for choice modelling surveys are impractical to achieve. One can improve data quality using more in-depth surveys administered to fewer respondents. We report on a study using high quality rank-ordered data elicited with the best-worst approach. The resulting "exploded logit" choice model, estimated on 64 responses per person, was used to study the willingness to pay for external benefits by visitors for policies which maintain the cultural heritage of alpine grazing commons. We find evidence supporting this approach and reasonable estimates of mean WTP, which appear theoretically valid and policy informative. © The Author (2011).
