This study examined who among the 526 fourth to sixth graders are nominated as among the coolest kids in their class. There were two questions: (1) Are popular-aggressive (tough) children nominated as cool by a broad spectrum of their peers, or only by a select few? (2) Does variability in children's cool nominations more closely follow their…

One source of potential difficulty for struggling readers is the variability of texts across grade levels. This article explores the use of automatic natural language processing techniques to identify dimensions of variation within a corpus of school-appropriate texts. Specifically, we asked: Are there identifiable dimensions of lexical and…

The authors administered measures of loneliness, generalized trust beliefs in peers, and trust beliefs in specific familiar peers (i.e., opposite-gender peers, same-gender peers, close same-gender peers) to a sample of 63 children (33 girls, 30 boys) from 4th and 5th grades (M age = 10 years, 6 months). They assessed children's trusting behavior…

This paper introduces a study aimed at ascertaining students' beliefs about mathematics and mathematical learning, as well as developing those beliefs and related variables by changing the classroom learning environment. Eighty-six fifth graders were involved, divided in two groups: one in the innovative learning environment (N=46) and the other…

The study analyses the effects of training primary school children in the use of a linguistic tool called "Exploratory Talk" (ET) on their capacity for argumentation. ET allows for reasoned confrontation and negotiation of points of view, making the reasoning visible in the talk. Eighty-eight Mexican children from the 5th and 6th grades…

This study examined the effects of a multifaceted, metacognitive vocabulary intervention on the reading comprehension and vocabulary achievement of fifth-grade children in one of California's lowest performing Title I schools. Instruction was comprehensive, designed to facilitate encoding of student-selected words, mastery of clarifying…

This article examines ethnic segregation, defined as segregation among racial groups as well as between native-born and immigrant students, across elementary school classrooms in New York City.

This study examined the relationship between oral reading fluency and performance on a statewide reading test across Grades 3, 4, and 5. A curriculum-based measure of oral reading fluency was administered to 3rd, 4th, and 5th graders who participated in the reading test from the Colorado Student Assessment Program (CSAP). A cross-sectional design…

This study investigated the psychometric properties of the Loneliness and Social Dissatisfaction Scale (LSDS) in a sample of African-American and Hispanic-American children. Participants were a non-clinical sample (N = 186) of children ages 11 to 13 in the fifth and sixth grades in a school in the Metropolitan New York area. Confirmatory factor…

In this paper, we analyze an investigative situation proposed to a class of 5th graders in a primary school. The situation is based on the following task: In a sale with group rates on a sliding scale, the students must find the lowest possible purchase price for a given number of tickets. A study of students' arguments made it possible to…

Two studies investigated children's metacognition about everyday reasoning, assessing how they distinguish reasoning from nonreasoning and "good" reasoning from "bad." In Study 1, 80 1st graders (6-7 years), 3rd graders (8-9 years), 5th graders (10-11 years), and adults (18+ years) evaluated scenarios where people (a) used reasoning, (b) solved…

Four fifth-grade classrooms embarked on a modified ubiquitous computing initiative in the fall of 2003. Two 15-computer wireless laptop carts were shared among the four classrooms in an effort to integrate technology across the curriculum and affect change in student learning and teacher pedagogy. This initiative--in contrast to other one-to-one…

This study investigated teachers' beliefs and practices of cooperative learning, and strove to determine whether their observed teaching practices reflected their stated beliefs.
