This article analyzes the distribution of mathematics achievement among class, school, municipality, and state in Argentina. Data from the Year 2000, 6th-grade Primary School Census from the Minister of Education are analyzed using multilevel methodology. The results indicate that all levels of the education system are relevant and must be…

Teachers and researchers have long recognized that students tend to misunderstand the equal sign as an operator; that is, a signal for "doing something" rather than a relational symbol of equivalence or quantity sameness. Students' equal sign misconception has been researched for more than thirty years (Weaver, 1971, 1973) with little…

Trends in International Mathematics and Science Study raised the concern that the United States (US) mathematics teachers place less emphasis on topics and teach a variety of content strands (Goldsmith, Mark & Kantrov, 2000; Kerachsky, 2008). The overall pattern in the US mathematics classrooms today is that primary and upper elementary…

Purpose: This study set out to investigate pupils' evaluations of their academic abilities in different school subjects and their ratings of their potential for improving their performance in those school subjects. Sample: Twenty-eight pupils from the third grade (approximately age nine) and 30 pupils from the sixth grade (approximately age 12) in…

Developing national identity is a goal of schools around the world. Historically this goal has been especially important for nations coming out of colonization as new governments seek to unify their nations and promote national identities. From 1842 to 1997, Hong Kong was a British colony whose excellent harbor made it a linchpin of British…

This article articulates how a "grasp of practice" serves as a reasoning resource for inquiry and citizenship abilities associated with nature of science (NOS) understanding. Theoretically, this resource is elaborated through an overlapping concern with "practice" in two literatures, science studies and psychology of learning, bringing attention…

The purpose of this study was to investigate the effect of cognitive behavioral therapy and cognitive behavioral therapy plus media on the reduction of bullying and victimization and the increase in empathy and bystander response in a bully prevention program for urban sixth-graders. Sixty-eight students participated. Because one of the…

Project BudBurst is a national program intended to get students and other "citizen scientists" to participate in a real study about plants, the environment, and climate change. It also provides an excellent opportunity for students to build data-analysis skills. A collaboration of several agencies and universities, the program began last year and…

This study examined the relationships between trait anxiety and anxiety sensitivity and the outcome variables posttraumatic stress disorder (PTSD) symptoms and somatic complaints following a major hurricane. Sixth and seventh graders in the New Orleans area (N=302) were surveyed 5 to 8 months following Hurricane Katrina. As expected, hurricane…

The vision of K-12 standards-based mathematics reform embraces a greater emphasis on students' ability to communicate their understandings of mathematics by utilizing adaptive reasoning (i.e., reflection, explanation, and justification of thinking) through mathematics discourse. However, recent studies suggest that many students lack the…

Background: To achieve high participation rates and a representative sample, active parent consent procedures require a significant investment of study resources. The purpose of this article is to describe processes and outcomes of utilizing active parent consent procedures with sixth-grade students from urban, ethnically diverse, economically…

This article examines the role of gesture in the shared meaning-making processes of 6th-grade students studying plate tectonics using a data visualization tool; specifically, a geographic information system. Students' verbal and gestural characterizations of key concepts of plate motions (i.e., "subduction", "rift", and "buckling") were…

Not too long ago, on a visit to two sixth-grade classrooms, the author saw very clearly the challenge teachers have before them when they try to differentiate reading. In both classrooms, 11-year-olds who read like fourth graders shared tables with classmates who read like the average ninth grader--a five-year span. How teachers approach this…

The purpose of this study was to describe and understand the range of outcomes of class visits to natural history museums. The theoretical framework is based on the multifaceted process of learning in free choice learning environments, and emphasizes the unique and individual learning experience in museum settings. The study's significance is in…

Fourth graders with learning disabilities in transcription (handwriting and spelling), LD-TD, and without LD-TD (non-LD), were compared on three writing tasks (letters, sentences, and essays), which differed by level of language, when writing by pen and by keyboard. The two groups did not differ significantly in Verbal IQ but did in handwriting,…
