Considerable evidence suggests that dialogical interaction in the classroom promotes students' scientific knowledge building and reasoning. Hence, scientific argumentation is recognized as a central component of the Next Generation Science Standards. A focus on argumentation, however, requires teachers to adopt instructional practices that…

This article reports on changes in science discourse practices of four teachers who participated in an extended professional development (PD) program. Teachers were selected for their different patterns of improvement in the quality of their classroom discourse during their participation in the program. Analyses of their practices to support…

There is international concern over persistent low rates of participation in postcompulsory science--especially the physical sciences--within which there is a notable underrepresentation of girls/women. This paper draws on data collected from a survey of more than 9,000 10/11-year-old pupils and 170 interviews (with 92 children and 78 parents)…

Internationally, there is widespread concern about the need to increase participation in the sciences (particularly the physical sciences), especially among girls/women. This paper draws on data from a five-year, longitudinal study of 10-14-year-old children's science aspirations and career choice to explore the reasons why, even from a young age,…

The concern about students' engagement with school science and the numbers pursuing the further study of science is an international phenomenon and a matter of considerable concern among policy makers. Research has demonstrated that the majority of young children have positive attitudes to science at age 10 but that this interest then declines…

Low participation rates in the study of science, technology, engineering, and mathematics (STEM) post-16 are a matter of international concern. Existing evidence suggests children's science aspirations are largely formed within the critical 10 to 14 age period. This article reports on survey data from over 9,000 elementary school children in…

Students' engagement with science and the numbers pursuing further study of science continue to be a concern among policy-makers, particularly in Western countries. Previous research reflects that most children have positive attitudes to science at age 10 but that, by age 14, attitudes towards and interest in further pursuit of science have…

One issue of interest to practitioners and researchers in science centres concerns what meanings visitors are making from their interactions with exhibits and how they make sense of these experiences. The research reported in this study is an exploratory attempt, therefore, to investigate this process by using video clips and still photographs of…
