Oral language and early literacy skills are theorized to provide the foundation for reading acquisition. To understand these relations, methods are needed that depict dynamic skill development in the context of reading acquisition. We modeled contributions of school-entry skills and early skill trajectories to later reading with 105 5-year-old…

Practitioners are encouraged to apply theories of reading development to psychoeducational test interpretation. Orthographic mapping provides an explanation of the acquisition of sight words. Although many test batteries provide tasks for practitioners to assess reading components associated with orthographic mapping, the relationship among…

While there is some evidence of a gap in English writing achievement between children with English as an additional language (EAL) compared to their monolingual English-speaking (EL1) peers, the source of this gap remains unclear. This study examines whether writing presents a specific challenge for children with EAL beyond their oral language and…

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…

Purpose: We conducted a randomized control trial of an instructional program, SRSD Plus, which integrates reading for writing to inform, writing, oral language, spelling and handwriting for students in Grades 1 and 2. Method: A total of 10 teachers and their 248 students in Grade 1 (n = 121) and Grade 2 (n = 127) in the southwestern part of the US…

Purpose: This study focused on factors that contributed to writing quality in adults who were pursuing a General Educational Development (GED) diploma through an adult basic education program and university students who were pursuing a college degree. We explored the role of transcription (handwriting and spelling), working memory, oral language,…

Background: Many individuals with autism spectrum disorders (ASD) exhibit social cognitive impairments in the development of theory of mind (ToM), or the ability to attribute mental states to oneself and others. ToM has been shown to relate to reading comprehension for children and adolescents with typical development (TD) and with ASD. This study…

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.…

We investigated the contributions of multiple strands of factors--individual characteristics (struggling reader status, working memory, vocabulary, grammatical knowledge, knowledge-based inference, theory of mind, comprehension monitoring), a text feature (narrative vs. expository genre), and question types (literal and inferential)--to one's…

The present study investigated the identification of end of first grade (n = 125) and end of third grade (n = 77) reading comprehension difficulties using beginning of first grade decoding-related and language-related predictors. Reading comprehension was defined using a composite of three standardized reading comprehension measures. Students at…

Nonmainstream American English, or dialect, among children may have important implications for reading research and practice. However, much of the research involving relations between dialect and literacy has analyzed dialect use in only one context and has omitted students with speech, language, and learning disabilities. Consequently, we…

By the end of primary school, students are confronted with expository texts known for their high proportion of domain-specific academic vocabulary words. These words usually comprise Greek or Latin roots in their internal structure. Recent findings showed that knowledge of Greek and Latin roots is related to reading comprehension. However, no…
