Given its important role in mathematics as well as its role as a gatekeeper to future educational and employment opportunities, algebra has become a focal point of both reform and research efforts in mathematics education. Understanding and using algebra is dependent on understanding a number of fundamental concepts, one of which is the concept of…

This study was designed to examine the relationship between preservice teachers' perceived body sizes and confidence in their ability to teach. One hundred two participants completed a questionnaire that included 1) providing height and weight information, 2) completing The Teaching Anxiety Scale (TCHAS), 3) selecting body images best representing…

The effects of class size on academic achievement have been studied for decades. Although the results of small-scale, randomized experiments and large-scale, econometric studies point to positive effects of small classes, some scholars see the evidence as ambiguous. Recent analyses from a 4-year, large-scale, randomized experiment on the effects…

Effective regulatory skills are essential in busy preschool classroom environments where children must maintain some control over their emotions and behavior to interact effectively with peers and teachers. Regulatory abilities can play a crucial role in a child's successful adjustment to preschool. We investigated whether individual differences…

The data obtained from high-school seniors for the Third International Mathematics and Science Study (TIMSS) for the country of Cyprus appear to be contradictory. Although Cypriot students did not perform well in mathematics in elementary school, middle school, and in the non-advanced sectors of high school, students in advanced mathematics…

School attachment is a robust predictor of adjustment in children and youth. Previous research has demonstrated effects of school context on student attachment, but individual-level contributions have not been explored. Our study examined the role of affiliative orientation in school attachment and aggressive behavior in children and youth from…

As adult Latina/Latino students advanced from a community college to a four-year college, a transition course and mentoring program engaged students and educators in a reciprocal process of change. (Contains 1 figure.)

The implications of the policy choices made in setting up a phased retirement system are demonstrated by its variety of outcomes. (Contains 5 tables.)

This chapter addresses how critical choices in the math and science pipeline can be traced back to adolescents' self-concepts of abilities and values at the beginning of high school. (Contains 3 figures.)

This study explored the gender differences in sexual self-concept, personal resources for sexual health, safe sex behaviors, and risky sexual behaviors among homeless adolescents with and without histories of sexual abuse. Data for this secondary analysis were collected in 2003 to 2004 in the first phase of a larger repeated-measures sexual health…

Because the National Science Education Standards (1996) outline specific things K-8 students should know about plants, and previous data indicated that elementary students had difficulty understanding some major ideas about plants and plant growth, the authors of this article thought it appropriate to initiate an investigation to determine the…

Background: Family quality of life (FQOL), as a family outcome measure of early intervention and other services, has increasingly drawn attention of researchers, policymakers and service providers. Developing an index of "family" QOL requires a measure suitable for use with multiple family members. The purpose of this study was to test whether…

This article analyzes the effects of the number of siblings, their sex composition, and other individualization indicators intertwined with the development of a beanpole-type kin structure on exchanges among generations in Spain. The effects of this development vary depending on the point of view adopted: that of the parents or that of the adult…

The social/behavioral characteristics of 63 preschool children with low and high language abilities were observed for 60 min during teacher-directed structured activities and 60 min during child-directed unstructured activities in Head Start classrooms. Children with low language were observed to have significantly higher rates of disruptive…

The article discusses selected findings of a narrative review, funded by the Institute of Physics, in response to the continuing decline in the number of girls studying physics post-16 in England; 177 selected sources, of national and international research literature about girls' participation in physics, were reviewed. In the article, we argue…
