Theoretical models have suggested that teachers' motivational beliefs relate to various student academic outcomes through particular teaching practices, and that teachers' motivational beliefs and teaching practices are reciprocally interrelated. However, these relations have rarely been tested in longitudinal work. We extend previous research by…

Previous research has documented reliable effects of teachers' judgments or expectations, respectively, on their students' school performance. However, the importance of those effects has been controversially discussed because of their limited effect size. The impact of teacher judgments on students' lives might have been underestimated due to a…

We examine the relevance of task exposure specificity in the development of self-efficacy evaluations among 15-year-old students in Organisation for Economic Co-operation and Development (OECD) countries. We use data from the 2012 edition of the Programme for International Student Assessment (PISA) to assess if students' self-efficacy evaluations…

This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

Some children struggle with mathematics. Among these children, some of them may be learners with mathematical difficulties. While research has revealed multiple deficits as candidate causes for mathematical difficulties and probable subtypes, the cognitive profiles of these subtypes are not fully understood. Moreover, we have yet to discover…

The relation between prior knowledge and learning has been investigated in many studies. However, a recent meta-analysis showed that most of these studies suffered from serious methodological shortcomings, as they failed to account for knowledge growth over time, possible ceiling effects for learners with high prior knowledge, moderating effects…

Self-concept in mathematics (MSC) and interest in mathematics are important predictors of whether a student will choose to major in a science, technology, engineering, or mathematics (STEM) field at university. Research on the big-fish-little-pond effect (BFLPE) has shown that both predictors are affected by the achievement composition of students…

Teacher judgments impact on students' academic development, yet studies have revealed only modest judgment accuracy. Identifying biases hampering judgment accuracy is crucial. The present study scrutinized one such bias, namely reference group effects on teacher judgments (i.e., systematic relations between class-average ability and teacher…

The purpose of this meta-analysis was to determine the relation between mathematics and working memory (WM) and to identify possible moderators of this relation including domains of WM, types of mathematics skills, and sample type. A meta-analysis of 110 studies with 829 effect sizes found a significant medium correlation of mathematics and WM, r…

The proliferation of information and divergent viewpoints in the 21st century requires an educated citizenry with the ability to critically evaluate information and make informed decisions. To meet this demand, adaptive epistemic understandings and beliefs about the nature of knowledge are needed, such as believing that scientific knowledge is…

Many adolescent learners have difficulty understanding the relevance of mathematics for their lives. This problem is particularly pernicious among Black and Latino adolescents who often face cultural stigma that can affect their perceived value of mathematics. The present study used concurrent nested mixed methods to explore this issue in 419…

Academic self-concept (ASC) is characterized by the dual nature of stability and change. That is, students strive for consistency in their self-concept but also receive achievement feedback that leads to changes in ASC. Only a few previous studies have scrutinized the stability of ASC. The STARTS model (Stable, AutoRegressive Trait, and State)…

Several studies have shown that rapid automatized naming (RAN) is a significant predictor of mathematics, but the nature of their relationship remains elusive. Thus, the purpose of this meta-analysis was to estimate the size of their relationship and determine the conditions under which they correlate. We used a random-effects model analysis of…

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…

The purposes of this study were to investigate the effects of an intervention designed to improve at-risk 4th graders' understanding of fractions and to examine the processes by which effects occurred. The intervention focused more on the measurement interpretation of fractions; the control condition focused more on the part-whole interpretation…
