The general public's responses to people with intellectual disabilities influence the likely success or failure of policies aimed at increasing their social inclusion. The present paper provides a review of general population based research into awareness, attitudes and beliefs regarding intellectual disability published in English between 1990…

The mathematical topic of inverse functions is an important element of algebra courses at the high school and college levels. The inverse function concept is best understood by students when it is presented in a familiar, real-world context. In this article, the authors discuss some misconceptions about inverse functions and suggest some…

This study investigated and compared the geometry knowledge and levels of pre-service elementary teachers from the United States and Taiwan. Forty pre-service teachers in Taiwan and 48 pre-service teachers in the United States at the beginning of their teacher education programs completed the Entering Geometry Test (EGT) and the van Hiele Geometry…

Global warming is one of the important environmental problems whose dangerous effects are increasing gradually. The study reported herein aimed to reveal student teachers' conceptions about global warming and the effect of biology teacher education program on their awareness of this environmental issue. An open-ended questionnaire was used to…

Behavioral scientists have struggled with units of measurement for as long as they have struggled with measurement itself. Psychology's sole attempt at an explicit unit of measurement--the Lexile Framework for Reading (Stenner, Burdick, Sanford, & Burdick, 2006)--has been and continues to be ignored by the psychometric "cognoscenti."…

This article presents Stephen Humphry's response to the commentaries for his article "The Role of the Unit in Physics and Psychometrics." The commentaries covered a range of important considerations and implications. Given that the author fully agrees with the majority of the content, attention will be confined mainly to points that call…

This study investigated the association between sex stereotypes and the sexual behaviour of Nigerian school-going adolescents. It also ascertained the effects of age and sex on adolescents' beliefs about sex stereotypes. The study sample consisted of 658 (male = 287, female = 371) adolescents from nine randomly selected secondary schools in three…

Colleen Vale makes the case for professional learning teams collaborating together to improve their teaching and hence children's achievement. In this article she describes how this may be done. Along the way the teachers explored the idea of equivalence and the common conceptions and misconceptions held by children in their classes.

The present study aims to identify the effectiveness of summer science camp experience on middle school students' content knowledge and interest towards biology. For this purpose, two instruments including reflective journal and pre-post questionnaire were developed by four researchers who are expert in science education. Besides, the instruction…

HIV, AIDS, STIs, and unwanted pregnancy continue to impact young adults in the U.S. at a disproportionate rate, particularly during the college years. Attributional style (i.e., locus of control) influences one's HIV risk. Internal locus of control indicates a lower risk of HIV infection, whereas an external locus of control signals an increased…

Despite significant investments over the past decade in the expansion and improvement of preschool programs, too many children, particularly poor children, enter kindergarten behind their peers. Because it is critical that voluntary pre-kindergarten (VPK) classrooms offer educational programs that both address the needs and developmental levels of…

This study explores the use of historical short stories as nature of science (NOS) instruction in thirteen secondary science classes. The stories focus on the development of science ideas and include statements and questions to draw students' and teachers' attention to key NOS ideas and misconceptions. This study used mixed methods to examine how…

In this article we critically examine how teachers and administrators in an urban high school identify and consider the challenges to parent involvement without either engaging in or disrupting normative constructions of the term parent involvement. It is in this unintentional misconstruction of the notion of parent involvement that school leaders…

Introduction. Missing data is a common problem in research and can produce severely misleading analyses, including biased estimates of statistical parameters, and erroneous conclusions. In its 1999 report, the APA Task Force on Statistical Inference encouraged authors to report complications such as missing data and discouraged the use of…

This study investigated the claim (e.g., Vosniadou & Brewer's, 1992) that children have naive ''mental models'' of the earth and believe, for example, that the earth is flat or hollow. It tested the proposal that children appear to have these misconceptions because they find the researchers' tasks and questions to be confusing and ambiguous.…
