    ABSTRACT: This study examined gains in written language as assessed by targeted curriculum-based measures (CBMs), and explored how these gains were affected by moderator variables of specific cognitive functions and student subgroups. The sample included 68 second grade students who were at risk for writing disabilities. Handwritten compositions were collected throughout a written language intervention at baseline, sessions 3, 5, 10, 13, 15, 20, 22, and termination. Specific CBM variables included Total Number of Words Written, Words Spelled Correctly, Correct Word Sequences, and Percentage of Correct Word Sequences. Using latent growth curve analysis, models were estimated for each of the CBMs, but the data showed poor model fit. Latent class groupings using cognitive variables and student subgroups significantly moderated the growth rate for written language assessed by specific CBMs. Although these latter findings reflected potential moderators of change in written language, the lack of model fit raised questions around the use of these CBM variables in monitoring writing progress for second grade students at risk for writing disabilities. Findings from this investigation revealed the measurement complexities that likely remain hidden from teachers and other professionals engaged in routine progress monitoring using CBM variables.

    ABSTRACT: In a randomized controlled trial, 205 students were followed from grades 1 to 3 with a focus on changes in their writing trajectories following an evidence-based intervention during the spring of second grade. Students were identified as being at-risk (n = 138), and then randomized into treatment (n = 68) versus business-as-usual conditions (n = 70). A typical group also was included (n = 67). The writing intervention comprised Lesson Sets 4 and 7 from the Process Assessment of the Learner (PAL), and was conducted via small groups (three to six students) twice a week for 12 weeks in accordance with a response-to-intervention Tier 2 model. The primary outcome was the Wechsler Individual Achievement Test-II Written Expression Scale. Results indicated modest support for the PAL lesson plans, with an accelerated rate of growth in writing skills following treatment. There were no significant moderator effects, although there was evidence that the most globally impaired students demonstrated a more rapid rate of growth following treatment. These findings suggest the need for ongoing examination of evidence-based treatments in writing for young elementary students.

    ABSTRACT: The primary purpose of this study was to examine several key questions related to the neuropsychological contributors to early written language. First, can we develop an empirical measurement model that encompasses many of the neuropsychological components that have been deemed as important to the development of written language? Second, once derived, will the neuropsychological components of this model remain stable over first and second grades or will the model change in its composition? Third, will the strength of the relationships between neuropsychological components and writing outcomes be constant over time, or will the strength of the relationships change over time? Finally, will the derived empirical model show significant concurrent and predictive relationships with written expression? The sample included 205 first grade students recruited from a single school district who were followed into the second grade via two cohorts: Measures were aligned with major neuropsychological components as extracted from theoretical models of written expression and available empirical findings examining the neuropsychological contributors to writing in children. These domains included fine-motor speed, language, short-term memory, long-term memory, and various attention/executive functions including working memory. Confirmatory factor analyses (CFAs) and longitudinal structural equation modeling (SEM) methods documented that three core latent traits were present and stable at both grades 1 and 2: Fine-Motor, Language, and Attention/Executive Functions. The overall model was highly related to written expression and spelling at both grades 1 and 2, with the first grade latent traits accounting for 52 and 55% of the variance in second grade written expression and spelling, respectively. At both grades, the Language and Attention/Executive Functions latent traits were more highly associated with written expression and spelling than the Fine-Motor latent trait.
