This study investigated whether individual differences in working memory (WM) moderate effects of 2 variations of intervention designed to improve at-risk 4th graders' fraction knowledge. We also examined the effects of each intervention condition against a business-as-usual control group and assessed whether children's measurement interpretation…

While it is hypothesized that providing instruction based on individuals' preferred learning styles improves learning (i.e., reading for visual learners and listening for auditory learners, also referred to as the "meshing hypothesis"), after a critical review of the literature Pashler, McDaniel, Rohrer, and Bjork (2008) concluded that…

Students identified by talent search programs were studied to determine whether spatial ability could uncover math-science promise. In Phase 1, interests and values of intellectually talented adolescents (617 boys, 443 girls) were compared with those of top math-science graduate students (368 men, 346 women) as a function of their standing on…

English language predictors of English and French reading development were investigated in a group of 140 children who were enrolled in French immersion programs. Children were first tested in kindergarten, and their reading achievement was tested yearly in both English and French from Grades 1 to 3, with word-level and passage-level measures that…

This article reviews progress toward the development of a cognitive theory of aptitude for learning and presents descriptive and precriptive goals for aptitude theories. Preliminary hypotheses about the nature of cognitive processes in aptitude for learning from instruction are reviewed. Twelve constituent points of the descriptive theory are…

To investigate the role expectation based rules governing formal reasoning performance, a battery of group and individual aptitude measures and formal reasoning tests were administered to 17-year-olds. Individual differences in usage of these rules were clarified by establishing an overlap between an aptitude model and formal reasoning.…

Several issues about component validity are examined by using covariance modeling to test hypotheses about the relationships between components, aptitude, and achievement. Support was found for cognitive components to model individual differences in verbal aptitude, decompose test validity, and differentially predict achievement. (Author/GK)

Graduate students completed questionnaires containing either past performance information alone or past performance information and aptitude scores for a hypothetical student. Low aptitude scores led to greater ability attributions, regardless of performance. High aptitude scores led to greater effort attributions given poor performance and to…

Evaluated the effect of listening to stories on children's vocabulary growth. Children acquired new vocabulary from listening to stories, with both frequency of exposure and teacher explanation of target words enhancing vocabulary learning. The interventions, however, were not sufficient to overcome the Matthew effect, as higher ability children…

The effects of imagery instructions on fifth-graders with differing abilities were examined through within-class analysis and analysis in which class effects were allowed to have influence. In the latter analysis there were significant Aptitude X Treatment interactions with subscores derived from paired-associate tasks. Interactions were…

Subjects were 103 ninth graders in a social science source. Neither instructional treatments varying in amount of structure and student participation nor personality alone contributed significantly to the prediction of achievement, but interactions between them did. Treatment effects depended on the student's verbal ability, manifest anxiety, and…

This study investigated the effects of learner-generated pictures on science learning relative to both a verbal strategy and a control condition, and to determine the role of individual differences. Results revealed weak effects favoring a drawing strategy for males and females, and a holistic strategy for females only. (Author/GK)

Causal modeling was used to examine how primary students' language ability interacted with pace and redundancy of instructional language during an expository science lesson to explain students' attention and learning. Language ability and pace, mediated by students' attention to the lesson, accounted for variance in learning outcomes. Higher…

An educational psychology course was taught to four classes of undergraduates according to four treatments that varied in the amount of teacher structuring and student participation. Aptitude, achievement, and attitude measures were administered. Generalized regression analysis indicated significant aptitude-treatment interactions for achievement…
