Trautwein, Ulrich; Ludtke, Oliver; Kastens, Claudia; Koller, Olaf – Child Development, 2006
In 2 studies, an expectancy-value framework was applied to investigate effort expended on mathematics homework. In Study 1 (2,712 students in grades 5, 7, and 9; mean age=13.37 years), lower homework effort was found in higher grades. The effects of intrinsic value on homework effort were higher in the older cohorts, whereas the effects of the…

Boone, Erin M.; Leadbeater, Bonnie J. – Journal of Research on Adolescence, 2006
While research shows that low levels of social acceptance and elevated body dissatisfaction increase risks for depressive symptoms among both girls and boys, little is known about protective factors that can mediate these risks. We test the hypothesis that positive team sports involvement mediates the effects of these risks on depression in a…

Stein, Martin; Burchartz, Birgit – Mathematical Thinking & Learning: An International Journal, 2006
The Invisible Wall Project analyzes problem-solving processes of children in Grades 3 and 4 and Grades 8 and 9. The central idea of the research is to use sets of tasks that are all unsolvable, which means they have a goal that cannot be reached. The unsolvability, however, is of a kind that can be understood even by younger children. In our case,…

Kliewer, Wendy; Sullivan, Terri N. – Journal of Clinical Child and Adolescent Psychology, 2008
Validity data are presented for a new measure of threat appraisals in response to community violence. Adolescents (N = 358; 45% male; 91% African American, M = 12.10 years, SD = 1.63) and their maternal caregivers participated in two waves of a longitudinal interview study focused on the consequences of exposure to community violence. Structural…

Shepardson, Daniel P. – Journal of Environmental Education, 2005
The author investigated students' ideas about what defines an environment and how these ideas change across grade level and educational experience. A total of 81 students were sampled: 18 seventh graders, 20 eighth graders, and 24 ninth graders from general biology, and 19 ninth graders from college preparatory biology. The environments task was a…

Alvermann, Donna E.; Hagood, Margaret C.; Heron-Hruby, Alison; Hughes, Preston; Williams, Kevin B.; Yoon, Jun-Chae – Reading Psychology, 2007
The purpose of this study was to explore whether or not adolescents who are deemed underachievers and who struggle to read school-assigned textbooks will engage with popular culture texts of their own choosing (e.g., magazines, comics, TV, video games, music CDs, graffiti, e-mail, and other Internet-mediated texts). The 60 student participants,…

Dodge, Kenneth A.; Greenberg, Mark T.; Malone, Patrick S. – Child Development, 2008
A dynamic cascade model of development of serious adolescent violence was proposed and tested through prospective inquiry with 754 children (50% male; 43% African American) from 27 schools at 4 geographic sites followed annually from kindergarten through Grade 11 (ages 5-18). Self, parent, teacher, peer, observer, and administrative reports…

Franklin, Bobby J.; Crain-Dorough, Mindy – Education Working Paper Archive, 2006
The National Governors' Association is urging states to develop a standardized cohort graduation rate definition and to develop data systems with quality data that can in turn be used to produce a reliable indicator. This paper is an examination of one state's graduation rate using the cohort method. The statistics generated are compared to a…

Kamii, Constance; Kysh, Judith – Journal of Mathematical Behavior, 2006
In individual interviews, 220 students in grades 4, 6, 8, and 9 were given one task, and 72 eighth graders were given three tasks to answer two questions: (a) Is a square the unit of measurement for an area for students in grades 4-8? and (b) Does a square have a space-covering characteristic for students in grade 8? The answers to both questions…

Johansson, Olof; Davis, Anna; Geijer, Luule – School Leadership & Management, 2007
This study presents policy and theory as they apply to diversity, equality and equity in Swedish social and educational policy. All education in Sweden should, according to the curriculum (Lpo 94, 1994, p. 5) be of equivalent value, irrespective of where in the country it is provided and education should be adapted to each pupil's circumstances…

Zimmer, Ron; Gill, Brian; Booker, Kevin; Lavertu, Stephane; Sass, Tim R.; Witte, John – RAND Corporation, 2009
The first U.S. charter school opened in 1992, and the scale of the charter movement has since grown to 4,000 schools and more than a million students in 40 states plus the District of Columbia. With this growth has also come a contentious debate about the effects of the schools on their own students and on students in nearby traditional public…

Pawley, Duncan; Ayres, Paul; Cooper, Martin; Sweller, John – Educational Psychology, 2005
The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a…
