Motivation is known to fluctuate, often declining, over time. Research on how motivation changes across school years is ubiquitous, yet little research examines changes in motivation within one school year. In this study, we model how third- through fifth-grade students' mathematics motivation (i.e., expectancies and values) changes over two years…

Aim: This study adopted a three-wave random intercept cross-lagged panel model to explore the longitudinal reciprocal relationships between (a) the teacher-student relationship (TSR) quality and (b) the parent-child relationship (PCR) quality and positive affect among Chinese primary school students. Samples: Two primary school student samples,…

In this meta-analysis of 54 longitudinal studies with over 58,000 students in kindergarten through 12th grade, we examined the predictive nature of early numeracy measured at or before the first year of formal schooling in relation to later mathematics. Results showed that early numeracy significantly predicted mathematics measured after 6 months…

This paper analyses the longitudinal use of electronic portfolios (hereafter ePortfolios) in craft studies across six years (2013-18). Eight comprehensive school students participated in the study, tracing their craft process activities via photos, narratives, and tapings from the third to the ninth grade. The data involved self-assessment by the…

This study examines the association between class size, teacher characteristics and five non-cognitive student outcomes (i.e., self-control, interpersonal skills, approaches to learning, externalizing and internalizing problem behaviors) in grades K-3. Individual fixed-effects, that control for observed and unobserved time-invariant factors,…

The present study tested the postulation that "knowledge begets reading, which begets knowledge." Using Random Intercepts Cross-Lagged Panel Models (RI-CLPM), we analyzed a U.S. nationally representative data set to examine the directionality and magnitude of the longitudinal relation between domain knowledge (operationalized as science…

In recent decades, an increasing number of students have pursued alternative educational options, including charter schools, as school choice has continued to expand. This trend was accelerated by the COVID-19 pandemic. While it is well established that students experienced widespread learning loss during the pandemic, it remains unclear whether…

As outlined by Benjamin Bloom, students working within a mastery learning framework must demonstrate mastery of the core prerequisite material before learning any subsequent material. Since many learning systems in use today adhere to these principles, an important component of such systems is the set of rules or algorithms that determine when a…

The Learning Through Play (LTP) at School Research Study Ukraine was a four-year intervention study funded by the LEGO Foundation and implemented by the Australian Council for Educational Research (ACER) and the Ukrainian Educational Research Association (UERA). The intervention was a two-year professional learning program that blended online, and…

Metacognition refers to the capacity to reflect upon our own cognitive processes. Its contribution to reading development, when children start building their orthographic lexicon, still remains unknown. Here, we evaluate the metacognitive efficiency of children aged between 6 and 7 years old (N = 60) in 5 experimental tasks; four linguistic tasks…

The present study tested the postulation that "knowledge begets reading, which begets knowledge." Using Random Intercepts Cross-Lagged Panel Models (RI-CLPM), we analyzed a U.S. nationally representative data set to examine the directionality and magnitude of the longitudinal relation between domain knowledge (operationalized as science…

While interdisciplinary approaches in the STEM subjects are widely advocated there are concerns that disciplinary learning can be compromised, especially in mathematics. The Interdisciplinary Mathematics and Science (IMS) project is a three-year longitudinal study in four Victorian primary schools that has developed a pedagogical approach to…

The Learning Through Play at School Research Study Ukraine was a four-year longitudinal intervention study funded by the LEGO Foundation and implemented by the Australian Council for Educational Research (ACER) and the Ukrainian Educational Research Association (UERA). The study was implemented between 2019 and 2024, during COVID-19 and the…

As a causal attribution, attributing academic success to giftedness might influence students' academic achievement. According to previous studies, students' self-regulated learning and negative learning emotions may mediate the association between achievement attribution and academic achievement. Therefore, the present study employed structural…

When teachers, researchers, and students describe productively responding to moments of failure in the learning process, what might this mean? Blending prior theoretical and empirical research on the relationship between failure and learning, and empirical results from four data sets that are part of a larger design-based research project, we…
