Traditional research on collaborative learning employs a "black box" approach that makes it difficult to gain a deeper understanding of the differential effects of collaborative learning. To make the black box transparent, researchers have studied the process of collaboration, in order to establish which interaction features are likely to make…

Improving reading rate can be difficult for poor readers. In this experiment, we investigated the impact of improvement in reading rate on other aspects of reading, including word recognition, decoding, vocabulary, and comprehension. Poor readers in Grades 2 or 4 (N = 123) were randomly assigned to 1 of 3 conditions: practice reading text at their…

This study capitalizes on recent advances in the reliable and valid measurement of classroom-level social processes known to influence children's social-emotional and academic development and addresses a number of limitations in our current understanding of teacher- and intervention-related impacts on elementary school classroom processes. A…

Students (n = 797) from 36 4th-grade classrooms were taught the control of variables strategy for designing experiments. In the instruct condition, classes were taught in an interactive lecture format. In the manipulate condition, students worked in groups to design and run experiments to determine the effects of four variables. In the both…

Although there is increasing awareness of the overrepresentation of ethic minority students--particularly Black students--in disciplinary actions, the extant research has rarely empirically examined potential factors that may contribute to these disparities. The current study used a multilevel modeling approach to examine factors at the child…

The purposes of this study were (a) to identify measures that when added to a base 1st-grade screening battery help eliminate false positives and (b) to investigate gains in efficiency associated with a 2-stage gated screening procedure. We tested 355 children in the fall of 1st grade and assessed for reading difficulty at the end of 2nd grade.…

This study examined how literal symbols affect students' understanding of algebraic expressions. Middle school students (N = 322) were randomly assigned to 1 of 3 conditions in which they were asked to interpret an expression (e.g., 4c + 3b) in a story problem. Each literal symbol represented the price of an item. In the c-and-b condition, the…

This study tested the efficacy of supplemental phonics instruction for 84 low-skilled language minority (LM) kindergarteners and 64 non-LM kindergarteners at 10 urban public schools. Paraeducators were trained to provide the 18-week (January-May) intervention. Students performing in the bottom half of their classroom language group (LM and non-LM)…

Results from a 2-year longitudinal study of 181 children from 4th through 5th grade are reported. Levels of growth in children's computation, word problem, and estimation skills by means of common fractions were predicted by working memory, attentive classroom behavior, conceptual knowledge about fractions, and simple arithmetic fluency.…

Two studies were conducted to investigate the construct validity of a measure of teachers' achievement goals. The first study involved 143 teachers. Factor analysis of responses to the measure revealed three factors assessing mastery, performance approach, and performance avoidance goals. In the second study, a nationally representative sample of…

The aim of the present study was to test the hypotheses that parents' academic expectations, their perception of children's cognitive ability, and their degree of involvement at home and school would predict children's academic achievement, and that there would be important differences in this achievement as a consequence of differences in…

This paper explores how the interaction between cognitive style, gender, and type of task predicts task outcome, particularly when presentation speed is varied. A sample of 91 11-year-old pupils completed the Cognitive Style Analysis. Pupils were assigned to one of two groups balanced for gender and cognitive style. Group 1 listened to a recording…

The self-worth theory of achievement motivation holds that in situations in which poor performance is likely to reveal low ability, certain students (known as self-worth protective students) intentionally withdraw effort in order to avoid the negative implications of poor performance in terms of damage to self-worth. In this study, evidence of…

Students with differing profiles of epistemological beliefs--their beliefs about personal epistemology, intelligence, and learning--vary in thinking, reasoning, motivation, and use of strategies while working on academic tasks, each of which affect learning. This study examined students' epistemological beliefs according to gender, school…

This article reviews theoretical and empirical work on the relations between child and adolescent peer experiences and high school graduation. First, the different developmental models that guide research in this domain will be explained. Then, descriptions of peer experiences at the group level (peer acceptance/rejection, victimisation, and crowd…
