Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated: (1) whether…

A longitudinal study was conducted to identify unique sources of individual differences in later understanding of the equal sign as a relational symbol of equivalence (i.e., formal understanding of mathematical equivalence). The sample included 141 children from a mid-sized city in the Midwestern United States (M[subscript age] = 6 years, 2 months…

Prior research supports the need for elementary-aged students with reading difficulties (RDs) to receive explicit systematic small-group evidence-based reading instruction. Yet for many students, simply receiving evidence-based reading instruction in a small-group setting is insufficient to reach the progress milestones needed to meet grade-level…

Background: Writing involves multiple processes, drawing on a number of language, cognitive, and print-related skills, and knowledge. According to the Direct and Indirect Effects model of Writing (DIEW; Kim & Park, 2019, "Reading and Writing," 32, 1319), these multiple factors have hierarchical, interactive, and dynamic relations.…

Developmental language disorder (DLD) and developmental dyslexia (DD) are two prevalent subtypes of Specific Learning Disabilities (SLDs; "Diagnostic and Statistical Manual of Mental Disorders" [5th ed.; DSM-5]). Yet, little information is available regarding the distinct challenges faced by adults with DLD and/or DD in college. The…

Although many studies have investigated links between maternal employment and children's wellbeing, less research has considered whether the stability of maternal employment is linked with child outcomes. Using unique employment calendar data from the Fragile Families and Child Wellbeing Study (N=2,011), an urban birth cohort study of largely…

Using a case study design, our research explored question generation as a reading comprehension strategy, focusing on the types of questions 4th- and 5th-grade students posed before, during, and after reading narrative text. The authors aimed to determine whether their participants are ready to pose the higher-level questions expected of them by…

The present study examined whether and how socioeconomic status (SES) predicts school achievement in science, technology, engineering, and math (STEM) using structural equation modeling and data from the National Institute of Child Health and Human Development Study of Child Care and Youth Development. The present inquiry addresses gaps in…

This study addresses the current debate about the beneficial effects of text processing software on students with different working memory (WM) during the process of academic writing, especially with regard to the ability to display higher-level conceptual thinking. A total of 54 graduate students (15 male, 39 female) wrote one essay by hand and…

Background: Although people with Williams syndrome (WS) are often characterized as friendly and sociable with relatively good general language abilities, there is emerging evidence of pragmatic difficulties and trouble comprehending aspects of non-literal language. Aims: The main aim was to investigate the comprehension of sarcasm, metaphor and…

Students with mild intellectual disability generally garner less individual attention in research, as they are often aggregated with students with moderate and severe intellectual disability or students with other high incidence disabilities. This study used the National Longitudinal Transition Study-2 (NLTS2) to look at the personal…

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that…
