Understanding of NOS (nature of science) appears as a prerequisite of a scientifically literate person. Promoting adequate understanding of NOS in pre-service physics teachers is, therefore, an important task of science educators. Before doing that, science educators must have information concerning their pre-service teachers' conceptions of NOS.…

Pundits, politicians, and business leaders continually make claims for what standardized tests can do, and those claims go largely unchallenged because they are in line with popular assumptions about what these tests can do, what the scores mean, and the psychology of human motivation. But what most of what these opinion leaders say--and the…

The aim of this study was to determine the effectiveness of teaching based on conceptual change overcome misconceptions of 9th grade high school students about the subject of air pressure. The sampling of the study was formed with two classes of 9th grade students from a general high school in the city-center of Trabzon. A quasi-experimental…

Along with inquiry-based teaching, exploring the elements of art can guide students to view and represent objects realistically. Understanding line, shape, color, value, form, space, and texture helps bridge the gap between what students actually observe and what their preconceived ideas about the object may be. This type of explicit instruction…

Identities are not only shaped by self-perception, but are influenced by others' perceptions of self as well. More pointedly, one's physicality or bodily self can be perceived differently depending upon the viewer. To that end, Turner (2002) notes, "faculty women of color experience multiple marginality, characterized by lived contradiction…

Current evidence is equivocal as to whether adolescent's perception of weight status is linked to both healthy and risky behaviors. This study examined the association between accurate and inaccurate perception of weight and self-reported health and risk behaviors among a diverse sample of obese, urban adolescents. Data were analyzed from 1,180…

Testing strategies centered around open-ended assessments are generally thought to result in deeper learning compared with close-ended questioning. However, the time requirements involved in grading open-ended assessments on exams often limit the feasibility of using such assessments. This article presents an index card questioning strategy…

In a German out-of-school laboratory, 293 medium-achieving 10th-grade students participated in a lesson unit about gene technology. They were divided into two groups (I-1, I-2), both of which followed the same hands-on lesson procedure. Students within I-2 were additionally confronted with alternative conceptions to central issues of the specific…

The social norms approach to health promotion has become remarkably popular in the last 20 years, particularly in the American college system. It is an alternative to traditional fear-based approaches of health education, which a growing body of research demonstrates is often ineffective in reducing alcohol and drug misuse. The social norms…

Background: The incidence of psychological, physical, and sexual violence in intimate dating relationships has a significant impact on young people. These issues are of great concern to researchers, educators, and administrators who strive to help youth be happy and healthy. This review focused on prevention and intervention efforts implemented in…

Given that A is longer than B, and that B is longer than C, even 5-year-old children can infer that A is longer than C. Theories of reasoning based on formal rules of inference invoke simple axioms ("meaning postulates") to capture such transitive inferences. An alternative theory proposes instead that reasoners construct mental models of the…

In this paper we argue that attempts to distinguish between categories of "dyslexia" and "poor reader" or "reading disabled" are scientifically unsupportable, arbitrary and thus potentially discriminatory. We do not seek to veto scientific curiosity in examining underlying factors in reading disability, for seeking greater understanding of the…

This paper examines the relationship between altruism and positive illusion, as formulated by Taylor and Brown (1988). It was predicted that, compared to the non-exemplary, general population, exemplary altruists would exhibit a higher level of positive illusion, which, in turn, suggests a higher level of mental health. Forty exemplary altruists…

This article points out an unexpected but common misconception by students dealing with the exponential distribution.

Groups are ubiquitous in outdoor education and while there is a lot of literature on groups, there is limited examination of the assumptions made about groups and the effects these assumptions have on the practices of outdoor education. I utilise some of Michel Foucault's (1992) tools to investigate literature on outdoor education groups.…
