One means of preventing the top of a pond from freezing involves running a circulating pump near the bottom to agitate the surface and expose it to air throughout the winter months. This phenomenon is similar to that of the flowing of streams in subzero temperatures and to the running of taps to prevent pipe bursts in winter. All of these cases…

This paper explores the role of sex and relationship education (SRE) in reducing teenage pregnancy rates. It critically examines some of the assumptions underlying the emphasis placed on SRE within the teenage pregnancy strategy ( SEU, 1999)--in particular, the view that ignorance of sexual matters plays a key part in teenage conception. An…

Berent, Steriade, Lennertz, and Vaknin (2007) [Berent, I., Steriade, D., Lennertz, T., & Vaknin, V. (2007). "What We Know about What We Have Never Heard: Evidence from Perceptual Illusions". Cognition, 104, 591-630] demonstrate that English speakers' perception of onsets that are unattested in their language mirrors their typological markedness.…

This brief is a companion to the policy brief entitled, "Discipline Policies, Successful Schools and Racial Justice," which reviewed the research on disciplinary exclusion from school and made several recommendations, including the following three for seeking policy change through legislation: (1) Federal and state policy should require…

This meta-synthesis of empirical and nonempirical literature analyzed 24 journal articles and book chapters that addressed the intersection of disability, [homo]sexuality, and gender identity/expression in P-12 schools, colleges and universities, supported living programs, and other educational and social contexts in Australia, Belgium, Canada,…

In this paper I reflect on perspectives presented by John Settlage as he examines the truth of the proposition that "many teacher educators harbour deficit perspectives about their pre-service teachers, presuming that their lack of exposure to economically, ethnically and linguistically diverse settings renders them deficient as future educators."…

The disappearance of traditional sex education during rites of passage in African societies has left many youth uncertain of where to look for information. Against this backcloth, the objectives of this study were to identify knowledge gaps amongst adolescents in Kenya regarding sexuality, HIV/AIDS and reproductive health. A thematic analysis was…

Object-oriented analysis and design (OOAD) is not an easy subject to learn. There are many challenges confronting students when studying OOAD. Students have particular difficulty abstracting real-world problems within the context of OOAD. They are unable to effectively build object-oriented (OO) models from the problem domain because they…

What are Turkish pre, elementary, middle, and high school students' force ideas? And, how do Turkish students' non-normative force ideas differ or be similar to the well-known force misconceptions reported in the literature? Students have false and persistent beliefs about the physical world and they struggle with challenging misconceptions based…

This is one in a series of policy briefs on key education issues prepared by the RAND Corporation for the Obama administration. Despite controversy, charter schools are increasing in numbers as alternatives to traditional public schools. Research finds that charter schools do not produce the predicted negative effects and that they have some…

Background: Trigonometry is an area of mathematics that students believe to be particularly difficult and abstract compared with the other subjects of mathematics. Trigonometry is often introduced early in year 8 with most textbooks traditionally starting with naming sides of right-angled triangles. Students need to see and understand why their…

Secondary school chemistry teachers' understanding of chemical equilibrium was investigated through interviews using the think-aloud technique. The interviews were conducted with twelve volunteer chemistry teachers in Hong Kong. Their teaching experience ranged from 3 to 18 years. They were asked to predict what would happen to the equilibrium…

This study explored the differences between eight-year elementary school pupils (before the curriculum reform) and nine-year elementary school pupils (soon after the curriculum reform) in Slovenia, as regards specific chemistry knowledge and motivation to learn chemistry. Altogether, 191 elementary school pupils participated in the study. The…

This paper discusses what chemistry students might see while working with animations found on the Internet and how these electronic illustrations can potentially interact to reinforce rather than resolve misconceptions about chemical principles that a student may possess. The Daniell voltaic cell serves as an example to illustrate the ways in…
