Dynamic Measurement Modeling (DMM) is a recently-developed measurement framework for gauging developing constructs (e.g., learning capacity) that conventional single-timepoint tests cannot assess. The current project developed a person-specific DMM Trajectory Deviance Index (TDI) that captures the aberrance of an individual's growth from the…

Mathematics growth trajectory plays a significant role to predict future outcomes and careers. We examined the existence of different growth trajectories in mathematics during the late elementary-school period (from Grades 4 to 6) and the relationship between the trajectory group classification and later mathematics achievement (Grade 8). Then,…

In today's world, technology and digital media are no longer separate, "other" than "natural" human and social life. Technology has become pervasive, transparent, reaching a "stable" form, no longer revolutionary. A new concept, "the post-digital," is emerging and gradually taking hold in a wide range of…

This study examined Cho's dynamic system model of creative problem-solving ability in a sample of 112 gifted and non-gifted students. The cluster analysis and t-test results indicated that students should be categorized into high and low performance groups. Students who scored three points or more across all attributes also had a higher likelihood…

Since 2016, third to fifth-grade students at a Title I elementary school have not met adequate yearly progress because 70% of students have not scored proficient on the end-of-grade mathematics assessment. The purpose of this qualitative case study was to explore the instructional approaches that elementary school teachers use to teach mathematics…

I investigated the relationships between mathematics achievement on the Iowa Assessments and the mastery of four epistemic actions: selecting, analyzing, computing, and representing. These epistemic actions play a crucial role in characterizing mathematical reasoning and are essential for solving mathematics problems in the Iowa Assessments across…

Elementary school teachers are increasingly being asked to teach computer science (CS)--a subject area with which they often have little familiarity. To address this gap, teacher professional development (PD) is a common approach for helping teachers become familiar with CS content. This paper describes a collaborative PD designed to accompany a…

We investigate fifth-grade students' identity work and science learning at the margins of a science classroom. By "margins" we refer to activities unrelated to formal classroom instructional content and practices, and which unfold across many settings and contexts, including the classroom itself, but also multi-party, social group…

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in…

Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

The role of children's receptive vocabulary knowledge in word and nonword reading (decoding) in an orthographically transparent language is debated. Moreover, we have little understanding of how the role of vocabulary might differ between monolingual children and bilingual children from immigrant families (or language minority bilingual children…

In this study, we examined the relations between perceived social-class discrimination, attachment, and behavior problems in a sample of Chinese migrant children in Beijing (age [X-bar] = 11.48, SD = 1.12; n = 179). Data were collected from two migrant schools in Beijing. The participants completed measures of perceived social-class…

This paper examines the effects of a morphological awareness intervention on the word reading and spelling skills of Grades 4 to 6 children with dyslexia. Sixteen children in eastern Ontario, Canada, received 20 hours of morphologically oriented instruction spread over 6 weeks and eight served as controls, and all received a battery of reading and…

Social media apps are being increasingly used by primary school children and this has influenced how they connect and communicate with others. Child use of social media has raised societal concerns about its impact on early development. To gain a deeper understanding of children's experiences with social media, children in grade 5 (N = 28; girls:…

This action research study sought to examine ways to narrow the racial discipline gap in South Carolina's elementary schools. Employing both the Critical Race Theory and BlackCrit in schools as the theoretical frameworks, the research delved into the narratives of teachers in grades 3rd through 5th, exploring their encounters with school-based…
