A sample of 144 s- and 150 fourth-grade Chinese children was recruited to investigate the influence of body-object interactions (BOIs) on word recognition, i.e., how easily they could interact physically with each word's referent. The moderation on this relationship of children's screen time for entertainment purposes (i.e., the viewing or use of…

Background: Upper elementary grade students encounter increasingly complex texts with abundant morphologically complex words. Despite the positive effects of morphology-based vocabulary instruction, emergent bilinguals with limited word reading skills may need additional support. Methods: This study investigated the effects of morphological…

The purpose of this feasibility study was to examine the potential impact of reading digital interactive e-books, Word Knowledge e-books (WKe-Books), on essential skills that support reading comprehension with third-fifth grade students. Students (N= 425) read two WKe-Books, that taught word learning and comprehension monitoring strategies in the…

There is now considerable evidence regarding the types of interventions that are effective at remediating reading disabilities on average. It is generally unclear, however, what predicts the magnitude of individual-level change following a given intervention. We examine new predictors of intervention gains that are theoretically grounded in…

The present study was conducted to explore how the relationships between reading comprehension constructs change according to word reading accuracy, as measured in a large convenience sample (n = 857) of school-aged students (Years 3-6) with reading difficulties. Multiple regression analyses containing interaction variables were conducted, to…

Background: Although the reading of science texts has been reported for high school learners, there is not much research on how younger learners engage with expository texts and how they develop academic language skills. In the instance of this study, the topic came from the curriculum content about animal reproduction. Aim: The study from which…

Word semantic knowledge (WSK) is crucial to the development of one's reading comprehension ability. A total of 608 students (208 poor readers in the experimental group and 200 poor readers in the control group one, and 200 typical readers in control group 2) from grade 4 participated in this study. Selected reading ability assessments were…

This article summarizes findings from a two-year randomized control trial, focusing on a subset of 194 fourth graders with reading comprehension scores at or below the 15th percentile. Students in the treatment condition received an average of 94 daily 30-min sessions of small group intervention implemented with fidelity by well-trained research…

Attention is correlated with reading, but the extent to which behavioral ratings and sustained attention relate to reading skills is unclear. We assessed 245 fourth and fifth grade struggling readers (mean age = 10.3 years) on behavioral ratings of attention, sustained attention, and reading over a school year. Contributions of behavioral ratings…

This article summarizes findings from a two-year randomized control trial, focusing on a subset of 194 fourth graders with reading comprehension scores at or below the 15th percentile. Students in the treatment condition received an average of 94 daily 30-min sessions of small group intervention implemented with fidelity by well-trained research…

Academic language has been identified as an important focus for instructing students about the quality of written composition they need to be successful in college and career. However, the role of academic language in written composition achievement is not well understood. This study explores the role of academic language skills in students'…

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,…

Orthographic processing -- the ability to perceive, access, differentiate, and manipulate orthographic knowledge -- is essential when learning to recognize words. Despite its critical importance in literacy acquisition, the field lacks a tool to assess this essential cognitive ability. The goal of this study was to design a computer-based…

Students were assessed on reading comprehension, word reading,…

The developmental trajectory of the use of morphemes is still unclear. We investigated the emergence of morphological effects on visual word recognition in German in a large sample across the complete course of reading acquisition in elementary school. To this end, we analyzed lexical decision data on a total of 1,152 words and pseudowords from a…
