We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades. Multivariate growth mixture modeling yielded four classes of combined reading and mathematics trajectories for students with LD. The largest class of students with LD (Class 2, 54.3%) showed mean T-scores for both achievement domains that averaged about 1 SD below the mean, with modest decline over time. Almost a quarter of the sample (Class 1, 22.3%) displayed mean T-scores in both achievement areas near the peer-normed average; these students were mostly White, from higher socioeconomic status (SES) backgrounds, and had experienced earlier identification as having an LD as well as shorter duration of LD service. Classifying heterogeneity in longitudinal trajectories of both achievement areas shows promise to better understand the educational needs of students identified with an LD.

The purpose of the study was to validate a writing motivation questionnaire that consists of four scales for first-year college writers-students with low writing skills in basic writing classes and students in typical first-year composition (FYC)-to investigate differences between these two groups and to examine the relationship of motivational constructs with writing quality. Participants were 371 college students (142 in basic writing classes and 229 in FYC). Students completed a 49-item motivation questionnaire with scales for goal-orientation, self-efficacy, beliefs, and affect about writing and wrote an argumentative essay. Confirmatory factor analysis provided evidence for the structural construct validity of all scales for both groups. Statistically significant differences between basic writers and FYC students were found on self-efficacy for grammar and strategies and on beliefs about the importance of substance and mechanics. Structural equation modeling found statistically significant positive relationships of essay quality with all three self-efficacy scales and belief about the importance of substance to good writing, as well as negative relationships with avoidance goal orientation and belief in the importance of mechanics. Limitations and implications for motivation and instruction of basic writing students and of adults with learning disabilities are discussed.

Stuttering is a disorder that affects about 1% of the population and manifests as speech disfluencies. Reading difficulties and disabilities are commonly found in this population. Nonetheless, speech disfluencies have not been explored in adult struggling readers (ASRs). In the current study, we examined the rate of stuttering in ASRs as well as the relationships between their speech fluency and reading skills. A total of 120 participants were interviewed about their experiences with reading and administered standardized reading and reading-related assessments. Speech fluency and the criterion for stuttering were based on the interview. About 18.3% of the sample met the criterion for stuttering. ASRs who stutter (ASRs-S) and ASRs who do not stutter (ASRs-NS) did not differ in their reading and reading-related skills. ASRs-S had higher rates of negative correlations between reading and reading-related skills compared with ASRs-NS. Correlation patterns between performance on standardized assessments point to higher rates of uneven skills or dissociations in ASRs-S. These findings may have implications for the assessment and instruction for ASRs.

There is a range of reasons why college students may be underprepared to read, but one possibility is that some college students are below a threshold of proficiency in the component skills of reading. The presence of thresholds means that when students fall below that threshold, their proficiency in that component skill of reading is not sufficient for there to be a relationship with comprehension performance. The present study assessed (a) whether there were thresholds in proficiencies in foundational skills, (b) whether students falling below the thresholds were disproportionately in developmental literary programs (i.e., institutionally designated as underprepared), and (c) the implications of being below the thresholds on engaging in strategic processing during reading. College students were administered assessments of foundational literacy skills, text comprehension, and strategic processing of texts. The sample included students who were enrolled in developmental literacy programs and students who were not. Thresholds were found in the foundational skills associated with word-, sentence-, and discourse-level processing. Participants below these thresholds were represented disproportionately by students determined to be underprepared for college and assigned to developmental literacy programs. Finally, students falling below the thresholds demonstrated lower reading strategy scores than students above the threshold.

The purpose of this special series five articles is to highlight issues regarding decoding, comprehension, oral language fluency, and writing for adults with low literacy skills. Our authors' samples include adults attending adult literacy programs, as well as those who are attending postsecondary programs who may or may not have official learning disability diagnoses. The authors address issues that are not often covered in adult literacy scholarship. Through this special series, we hope to highlight the importance of, and directions for, future research on adults with low literacy skills, including individuals with specific learning disabilities.

As access to higher education increases, it is important to monitor students with special needs to facilitate the provision of appropriate resources and support. Although metrics such as the "reading readiness" ACT (formerly American College Testing) of provide insight into how many students may need such resources, they do not specify why a student may need support or how to provide that support. Increasingly, students are bringing reading comprehension struggles to college. Multiple-choice Online Causal Comprehension Assessment-College (MOCCA-College) is a new diagnostic reading comprehension assessment designed to identify who is a poor comprehender and also diagnose why they are a poor comprehender. Using reliability coefficients, receiver-operating characteristic curve analysis, and correlations, this study reports findings from the first year of a 3-year study to validate the assessment with 988 postsecondary students who took MOCCA-College, a subset of whom also provided data on other reading assessments (i.e., ACT, n = 377; Scholastic Aptitude Test [SAT], n = 192; and Nelson-Denny Reading Test [NDRT], n = 78). Despite some limitations (e.g., the sample is predominantly females from 4-year institutions), results indicate that MOCCA-College has good internal reliability, and scores are correlated with other reading assessments. Through a series of analyses of variance (ANOVAs), we also report how students identified by MOCCA-College as good and poor comprehenders differ in terms of demographics, cognitive processes used while reading, overall comprehension ability, and scores on admissions tests. Findings are discussed in terms of using MOCCA-College to help gauge which students may be at risk of reading comprehension difficulties, identify why they may be struggling, and inform directions in actionable instructional changes based on comprehension processing data.

Comprehension monitoring is a meta-cognitive skill that is defined as the ability to self-evaluate one's comprehension of text. Although it is known that struggling adult readers are poor at monitoring their comprehension, additional research is needed to understand the mechanisms underlying comprehension monitoring and their role in reading comprehension in this population. This study used a comprehension monitoring task with struggling adult readers, which included online eye movements (reread and regression path durations) and an offline verbal protocol (oral explanations of key information). We examined whether eye movements predicted accuracy on the passages' reading comprehension questions, a norm-referenced reading assessment, and an offline verbal protocol after controlling for age and traditional component skills (i.e., decoding, oral language, working memory). Regression path duration uniquely predicted accuracy on the questions; however, decoding and oral vocabulary were the most salient predictors of the norm-referenced reading comprehension measure. Regression path duration also predicted the offline verbal protocol, such that those who exhibited longer regression path duration were also better at explaining key information. These results contribute to the literature regarding struggling adults' reading component skills, eye movement behaviors involved in processing connected text, and future considerations in assessing comprehension monitoring.

The purpose of this study was threefold: to examine unique and shared risk factors of comorbidity for reading comprehension and word-problem solving difficulties, to explore whether language minority (LM) learners are at increased risk of what we refer to as higher order comorbidity (reading comprehension and word-problem solving difficulties), and to examine the profiles of at-risk LM learners compared with at-risk non-LM learners. At-risk (LM n = 70; non-LM n = 89) and not-at-risk (LM n = 44; non-LM n = 114) students were evaluated on foundational academic (word reading, calculation), behavioral (behavioral attention), cognitive (working memory, processing speed, nonverbal reasoning), and language (vocabulary, listening comprehension) measures in English. Results indicated listening comprehension was the only shared risk factor for higher order comorbidity. Furthermore, LM learners were 3 times more likely to be identified as at risk compared with non-LM learners. Finally, among at-risk learners, no differences were found on cognitive dimensions by language status, but LM learners had lower reading and listening comprehension skills than non-LM learners, with a relative advantage in behavioral attention. Results have implications for understanding higher order comorbidity and for developing methods to identify and intervene with higher order comorbidity among the growing population of LM learners.

This article presents the application of the interactive dynamic literacy (IDL) model (Kim, 2020b) toward understanding difficulties in learning to read and write. According to the IDL model, reading and writing are part of communicative acts that draw on largely shared processes and skills as well as unique processes and skills. As such, reading and writing are dissociable but interdependent systems that have hierarchical, interactive, and dynamic relations. These key tenets of the IDL model are applied to the disruption of reading and writing development to explain co-occurrence of reading-writing difficulties using a single framework. The following hypotheses are presented: (a) co-occurrence between word reading and spelling and handwriting difficulties; (b) co-occurrence of dyslexia with written composition difficulties; (c) co-occurrence between reading comprehension and written composition difficulties; (d) co-occurrence of language difficulties with reading difficulties and writing difficulties; (e) co-occurrence of reading, writing, and language difficulties with weak domain-general skills or executive functions such as working memory and attentional control (including attention-deficit/ hyperactivity disorder [ADHD]); and (f) multiple pathways for reading and writing difficulties. Implications are discussed.

The present study investigated the phonological and semantic aspects of written word learning among children with dyslexia, taking into account their use of phonetic and semantic cues embedded in words. Fifty-three Mandarin-speaking fifth graders were taught the pronunciations and meanings of 24 Chinese single-character pseudowords (children with dyslexia: n = 27; age-matched peers: n = 26). The regularity of phonetic cues and the transparency of semantic cues embedded in the characters were experimentally manipulated. Children's learning outcomes in orthography-to-pronunciation associations (learning the pronunciations of novel characters) and orthography-to-meaning associations (learning the meanings of novel characters) were examined separately. Results indicated that children with dyslexia performed more poorly than did their peers only in the learning stage of orthography-to-pronunciation learning. Otherwise, children with dyslexia demonstrated comparable performance in orthography-to-meaning learning, in the use of embedded pronunciation and meaning cues, and in retention of learning in comparison with their peers. Children applied phonetic and semantic cues jointly in the learning stage. For the 1-week retention, phonetic cues supported children's performance on the task of orthography-to-pronunciation associations, whereas semantic cues aided in that of orthography-to-meaning associations. These findings expand our knowledge of children with dyslexia and provide insights for future reading interventions.
