The COVID-19 pandemic disrupted school, work, and daily life on a global scale. In the wake of this unprecedented health crisis, schools across the United States were forced to abruptly adapt their educational delivery models. Understanding how student learning trajectories shifted throughout the ongoing pandemic is critical for equipping…

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,…

The goal of this longitudinal study was to examine developmental trajectories of emotional school engagement among Chinese elementary school children. In addition, we sought to explore the role of early peer relationships and academic achievement as predictors of these trajectories. Participants at the outset of the study were N =…

A design experiment where students in Grade 5 (11-12 years old) play the Color Run game constitutes the context for investigating how students can be introduced to informal hypothesis testing. The result outlines a three-step hypothetical learning trajectory on informal hypothesis testing. In the first step, students came to favor sample space…

Background/Context: Developing strong number sense and additive reasoning in the early grades is a critical foundation for success in school and beyond. Longitudinal studies show that early competence with number and operations predicts later math achievement, reading achievement, high school retention rates, and employability and wages in…

Studies have shown how family (typically parents) and formal institutions (specifically schools and universities) shape individuals' dispositions--or "habitus." However, other sites of academic socialisation, such as tutoring centres and coaching institutions (collectively forming a shadow education system), are seldom scrutinised for…

Recent research suggests the benefits of supporting a progressive understanding of concepts of inference prior to the teaching of procedures and formal calculations through the study of informal statistical inference (ISI). To contribute to the growing knowledge about the early learning and teaching of statistics, particularly regarding the…

Understanding how young learners come to construct viable mathematical arguments about general claims is a critical objective in early algebra research. The study reported here characterizes empirically developed progressions in Grades K-1 students' thinking about arguments concerning sums of evens and odds. Data are drawn from classroom lessons…

This study described the growth trajectories of 105 children (n = 55 boys) who had just started primary school in New Zealand (NZ). Children were assessed every fourth school week around 1.5 months after starting school, for five sessions on Dynamic Indicators of Basic Early Literacy Skills first sound fluency (FSF), AIMSweb letter sound fluency…

In 2020, two teachers and seven students participated in an action research project that sought to improve the teaching and learning of fractions in a New Zealand primary school. This research revealed that the collaborative creation of hypothetical learning trajectories was beneficial to the teachers' practice, content knowledge, and confidence,…

There is little empirical research related to how elementary students develop computational thinking (CT) and how they apply CT in problem-solving. To address this gap in knowledge, this study made use of learning trajectories (LTs; hypothesized learning goals, progressions, and activities) in CT concept areas such as sequence, repetition,…

Educators are concerned that children make progress in their learning. While there are both policy and professional debates about how progress should be monitored and assessed, the views of children are rarely considered. Grounded in the 'voiced' research tradition, this paper reports on 158 focus group interviews with upper primary school…

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…

The present study examined the production of inalienable possession with body parts in Spanish among 20 school-age children of Mexican-born parents born and raised in the United States. The results were compared to those of 20 first-generation immigrant parents (main input providers), 27 Spanish-dominant children of similar age, and 12 Spanish…
