Early academic skills and behavioral characteristics in students are predictive of later school achievement, but academics and behavior are commonly compartmentalized in research and practice. This study investigated to what extent first-grade early numeracy (EN), literacy, and behavior ratings predicted fourth-grade mathematics achievement. In…

Background: Oral language has long been acknowledged as a prominent influence on children's reading development. Here, we examine the intersecting contribution of two prominent aspects of oral language - phonology and morphology. We explore this interface by examining contributions from the two dimensions of phonology - phonemic and prosodic - of…

Relationships with parents and teachers are crucial to a child's socialization. However, little is known about the transactional processes between parent-child and teachers-student relationships and their mediating mechanisms. This short-term longitudinal study examined bidirectional relations between positive parent-child and teachers-student…

Previous studies uncover that vocabulary knowledge may be related to compound structure awareness (the awareness of relational structure embedded in compound words), and they both contribute to reading comprehension. Yet, limited studies have examined the dynamic relationship between vocabulary knowledge and compound structure awareness, or their…

This research aims at exploring in an irregular orthographic system like French, if spelling is related to written composition. French spelling is particularly interesting because it includes phonographic irregularities (i.e., inconsistencies), lexical difficulties and numerous morphological silent marks (e.g., plural noun, adjective, and verb…

The current study examined the potentially changing relations of vocabulary knowledge and attentional control with word reading and spelling from Grade 2 to Grade 4. Spelling was scored using a conventional correctness score and an alternative nonbinary scoring method that reflects the degree of correctness (i.e., text distance). A total of 165…

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…

Purpose: This longitudinal study examined the contribution of preschool morphological awareness to word reading skills and reading comprehension, as well as to the developmental change of reading ability beyond other well-established oral language and cognitive predictors. A distinction was made between the domains of inflectional and derivational…

Engagement and academic achievement are generally correlated among elementary school students without learning disabilities (LDs). However, it is unclear if this pattern holds for students with LDs, who have lower achievement and engagement than their peers. This study examined whether links between achievement and student-reported behavioral…

Ethnolinguistic minority students may have lower levels of metacognitive knowledge and English vocabulary knowledge than non-minority students. Nevertheless, few longitudinal studies have examined their growth trajectories of metacognitive knowledge and English vocabulary knowledge over time. Drawing upon a latent growth curve model, the present…

Background: Learning is a self-regulated loop where learning strategies and achievements are interrelated. In reading, although some studies have explored the relationship between different learning strategies (memorization, elaboration and control) and reading achievement, little is known about how they interact over time. Even though the…

This study aims to understand individual differences between children in metacognitive monitoring and control processes and the developmental trajectories of metacognition over one year. Three indicators of procedural metacognition were used: monitoring accuracy (discrimination of confidence judgments between correct and incorrect test responses),…

Engagement and academic achievement are generally correlated among elementary school students without learning disabilities (LDs). However, it is unclear if this pattern holds for students with LDs, who have lower achievement and engagement than their peers. This study examined whether links between achievement and student-reported behavioral…

To examine developmental processes, intervention effects, or both, longitudinal studies often aim to include measurement intervals that are equally spaced for all participants. In reality, however, this goal is hardly ever met. Although different approaches have been proposed to deal with this issue, few studies have investigated the potential…

In order to investigate the influence of separation of grade distributions and ratio of common items on the precision of vertical scaling, this simulation study chooses common item design and first grade as base grade. There are four grades with 1,000 students each to take part in a test which has 100 items. Monte Carlo simulation method is used…
