Background: The home learning environment (HLE), along with center-based early childhood education (ECE) programs, plays an essential role in promoting early childhood development (ECD). HLE can become more or less stimulating over time due to caregivers' tendency to adapt HLE in response to preschoolers' evolving developmental status, of which…

This study is the first to explore microdevelopment in sociolinguistic evaluative judgments of standard German and Austro-Bavarian dialect by adult second language learners of German by using dense time serial measurements. Intensive longitudinal data (10 observations per participant) were collected from four learners at approximately weekly…

The relation between reading and mathematics achievement is an active area of research, and evidence in the extant literature suggests they are closely related. However, there is a lack of understanding about how their relation develops over time. Indeed, traditional longitudinal analyses have focused on investigating each domain independently,…

Studying abroad entails international students' identity (trans)formation and social network development, but individuals' decisions and choices while engaging in these processes remain underexplored. Informed by the notion of agency in second language socialization theory, this longitudinal case study examined the interplay of identity and social…

The study of the process of becoming a student is currently a key issue in educational science and psychology research. However, there is no consensus on its definition. Based on a redefinition of the concept from a psychodevelopmental and contextual perspective (Bronfenbrenner, 2005; Malrieu, 1973), the aim of this study is to document the inter-…

This study introduces a longitudinal diagnostic classification model, called the LTA+HDCM, which is a fusion of latent transition analysis (LTA; Collins & Flaherty, 2002; Collins & Wugalter, 1992) and the hierarchical diagnostic classification model (HDCM; Templin & Bradshaw, 2014). The primary goals in this study are (1) to evaluate…

Understanding math and the ability to use math in various situations can greatly contribute to a successful life. Different math skills are of importance for understanding and supporting math ability. In addition, math interest may influence math ability. We investigated the relationship between math conceptual and procedural skills, their…

Multilingual learners (MLs) represent an increasing proportion of public school students. Although much attention has been given to their academic performance in English language arts and math, less research has addressed their academic performance in science, particularly in elementary school. This study leveraged nationally representative data…

Students struggle to acquire the needed energy understanding to meaningfully participate in the energy discourse about socially relevant topics, such as energy transformation or climate change. Identifying students on differing learning trajectories, as well as differences in knowledge used, is essential to help students achieve the needed energy…

Longitudinal analyses have revealed informative patterns about health, mental health, adaptive skills, autism symptoms, and social skills during the transition to adulthood for autistic individuals. This study expands on these findings by investigating the trajectories of positive affect from age 15 to 30 years using a heterogeneous cohort (n =…

This mixed methods study investigated the change types and the underlying mechanisms of Chinese undergraduates' deep learning approach at a research-oriented university in eastern China. In Study 1, the deep learning approach of 273 freshmen was assessed using R-SPQ-2F at the beginning and end of a semester. The changes were categorized into three…

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…

In this report, we perform an analysis of kindergarten readiness in Illinois and relate it to students' third grade academic achievement. We study two cohorts of Illinois kindergarteners and follow them into third grade using data provided by the Illinois State Board of Education (ISBE). We summarize our key findings below: (1) Disparities appear…

While achievement gaps have been widely studied, less attention has been given to how these gaps relate to students' patterns of "academic mobility"-- that is, how students' relative academic standing changes from early to later grades. Using rich administrative data from Washington state, we apply an academic mobility framework to…

Grade retention, the practice of holding a student back in the same grade, has been a controversial topic in the United States for decades. English learners, a growing population in US schools, are consistently identified for grade retention more often than their English-only counterparts. The purpose of this study is to test the impact of grade…
