Solving word problems is challenging for many children, but particularly for those with language difficulties. The objective was to examine the nature of the challenges experienced by children with language difficulties as they solved word problems in the context of a developmental-trajectory instructional sequence. We recruited 45 third graders…

This study examined how word-problem characteristics influenced students' learning and retention of word-problem knowledge during and after an intervention. The participants were 221 fourth-grade students (average age at pretest = 8.8 years) who experienced word-problem difficulties (WPD) and had received a word-problem intervention in third…

Our work investigated how six primary school students used a non-traditional method for adding and subtracting: the ABN method, a Spanish acronym for Open (method) Based on Numbers. Commognitive theory [Sfard, A. 2008. "Thinking as Communicating: Human Development, the Growth of Discourses, and Mathematizing." New York: Cambridge…

Elementary school students with or at risk for emotional and behavioral disorders (EBD) are likely to experience social difficulties and challenges with peer relationships (e.g., victimization, rejection, isolation, and negative peer influence). A particularly salient influence on students' classroom-based social experiences is how they are…

Understanding achievement and discipline trajectories of Latinx students is critical given disproportionate dropout/pushout rates of Latinx students from schools across the U.S. Using a Critical Race Theory framework, the current study examined longitudinal associations amongst a sample of (N = 1672) Latinx youths' school readiness at kindergarten…

Poor reading has been linked to negative outcomes on a wide range of emotional-behavioural dimensions in children. However, little is known about the time course of these associations. In this study we analyse data from a sample of Finnish children (N = 199; 106 boys) which included measures of reading fluency in grade 1 (age 7 or 8), and…

Parental knowledge is often the result of parents soliciting information from their child and their child's disclosure of that information. Although child disclosure is most closely (and negatively) associated with behavior problems in adolescence, it is not yet known whether this is also the case in childhood. The aim of this study was to examine…

The present pilot study outlines findings from a study that evaluated the efficacy of educational robots in enhancing children's cognitive skills and historical knowledge. Applying LEGO® Wedo 2.0, the study focused on typically developing nine-year-old students in a K-12 public school setting. The hypothesis posited that students using robotics…

The basic notions of combinatorics, including systematic listing and permutations, are important topics of mathematics that are recommended to be learned eventually from elementary schools. However, there is little research in mathematics education regarding elementary students' combinatorial strategies. The purpose of this research is to…

Arithmetic fluency is regarded as a foundational math skill, typically measured as a single construct with pencil-and-paper-based timed assessments. We introduce a tablet-based assessment of single-digit fluency that captures individual trial response times across several embedded experimental contrasts of interest. A large (n = 824) cohort of…

The concrete-representational-abstract (CRA) approach is an instructional framework for teaching math wherein students move from using concrete materials to solve problems to using visual representations of the materials, and finally abstract concepts. This study provides a literature synthesis and meta-analysis of the effectiveness of the CRA…

Problem-based learning (PBL) offers a powerful approach to engage students in meaningful learning experiences by connecting classroom content to real-world challenges. This Spotlight explores how PBL can be implemented across K-12 to foster critical thinking, collaboration, and problem-solving skills. From preparing students for the workforce…

This study examines the impact of constructivist methods on students' performance in mathematical problem-solving, which is a significant issue in contemporary educational research. Traditional teaching methods, which are often oriented towards rote learning and memorization, have limitations in increasing students' performance in solving…

Longitudinal study of associations between family-level emotion socialization and adolescent adjustment is limited. When American children (53.5% girls) were in second grade (N = 213; M[subscript age] = 7.98; data collected 2002-2003), mothers and fathers (79.8% of mothers and 74.2% of fathers were White) reported on their reactions to children's…

We study the peer effects of grade retention in the context of Indiana's statewide third-grade retention policy. When a retention occurs, it changes the peer group for two cohorts: rising fourth graders who lose a peer and rising third graders who gain a peer. We identify peer effects in both cohorts by leveraging plausibly exogenous variation in…
