Executive function (EF) training has shown promise for remedying general EF deficiencies faced by students with mathematics difficulty (MD) and for improving their performance. However, latest research also suggests that the instant and sustained effects of EF training remain inconsistent. In this study, 32 Chinese students with MD, age 7 to 10…

Fraction arithmetic facility is fundamental to learning more advanced math topics. However, attaining the ability to add and subtract fractions is hard for many students. The present longitudinal study examined students' growth on simple addition and subtraction word problems between fourth and sixth grades (N = 536). Latent class growth analyses…

Poor comprehenders are a significant subgroup of poor readers who, due to their ability to read aloud accurately, are often difficult to identify. This study aimed to determine whether assessment using two oral language tasks, mapped onto the two components of the Simple View of Reading, would provide an efficient approach to identification.…

This study examined the contribution of three writing enabling skills (i.e., feedback perception, self-efficacy, and self-regulation) on writing performance among Hispanic students. Participants were 261 students in grades 3-5. Approximately 60% of students were Emerging Bilingual (EB) enrolled in dual language programming. Students completed…

Student motivation to write is a pivotal factor influencing their writing achievement. However, individual motivation to write is not independent of the learning environment. It also is crucial for teachers to develop their own efficacy, knowledge, and ability in writing and writing instruction to help them utilize effective instructional methods…

The purpose of this study was to examine whether group-based differences exist in word- and text-level reading in a clinical sample of students with dyslexia, and to shed light on the cognitive processes supporting these essential skills. Second- through seventh-grade students were administered a battery of standardized measures of cognitive…

Current mathematics curricula and assessments emphasize students' ability to communicate mathematical reasoning in writing. Limited research exists, however, on what mathematics writing (MW) is and how to assess the quality of MW. Therefore, based on our definition of MW construct, we explored 4 approaches to scoring MW: (a) holistic rubric…

According to the RAND model framework, reading comprehension test performance is influenced by readers' reading skills or reader characteristics, test properties, and their interactions. However, little empirical research has systematically compared the impacts of reader characteristics, test properties, and reader-test interactions across…

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.…

This article reports the results from a study investigating the effects of a discipline-specific reading and writing intervention (I3C/PROVE IT!) with fourth and fifth graders. Participants included 237 students with writing difficulties (WD) from an initial pool of 608 upper elementary school students in a larger study. Teachers and students were…

We investigated 2 hypotheses of a recently proposed integrative theoretical model of reading, the direct and indirect effects model of reading (DIER; Kim, 2017b, 2019): (a) hierarchical relations and (b) dynamic relations (or differential relations) of skills to reading comprehension. Students were assessed on reading comprehension, word reading,…

Dysgraphia, a specific learning disability, impairs legible and automatic letter production by hand, which can interfere with written composing. The goal of the current study was not to investigate effective methods for teaching self-regulated writing to students with dysgraphia, but rather to investigate their self that is involved in their…

The purpose of this dissertation was to investigate the extent to which the Test of Everyday Attention for Children (TEA-Ch) in isolation and in combination with parent ratings of inattention predicted performance on reading comprehension assessments presented in various formats (question and answer, cloze, and recall) among a non-clinical sample…
