We Have to Talk About Something: Why NOT Talk About the Curriculum? A Guide to Embedding Language Interventions in Curricular Content.

PURPOSE: Children with developmental language disorder frequently have difficulty with both academic success and language learning and use. This clinical focus article describes core principles derived from a larger program of research (National Science Foundation 1748298) on language intervention combined with science instruction for preschoolers. It serves as an illustration of a model for integrating language intervention with curricular content delivery. METHOD: We present a five-step model for a speech-language pathologist and other school professionals to follow to (a) understand the grade-level core curriculum objectives; (b) align intervention targets with the curriculum; (c) select a therapy approach that aligns with both goals and curricular content, and (d) methods for implementing the intervention; and (e) verify that both the intervention and the curriculum have been provided in accordance with best practices. We apply this model to the Next Generation Science Standards, a science curriculum popular in the United States, and to grammar and vocabulary interventions, two areas of difficulty for children with developmental language disorders, though it would be possible to extend the steps to other curricular areas and intervention targets. CONCLUSIONS: We conclude by discussing the barriers and benefits to adopting this model. We recognize that both speech-language pathologists and teachers may have limited time to implement language intervention within a general education curriculum, but we suggest that the long-term benefits outweigh the barriers.

Preparing Student Clinicians to Provide Recast Therapy on Complement Clauses: A Training Program.

PURPOSE: This study reports on a program to train student clinicians to provide recast therapy on complement clauses to children with developmental language disorder (DLD). To determine the efficacy of the program, we conducted secondary data analysis based on Owen Van Horne et al. (2023) and examined student clinicians' recasts after training and children's progress after treatment. METHOD: Three student clinicians received a two-stage training, followed by a real intervention program targeting complement clauses in six children with DLD. A third of the intervention sessions were coded for the total number and number of unique verbs in complement clauses provided by the student clinicians. An elicited production task was completed to test children's knowledge of the target structure. RESULTS: On average, student clinicians provided 30 targeted recasts to each child during each intervention session. They provided a greater number of and more variable input for that compared to WH complements. Children demonstrated significant improvement only in WH, but not in that, complements. CONCLUSIONS: A targeted training program could strengthen clinicians' ability to provide recast therapy on complex syntax; however, future refinements should shorten and broaden training to include more targets. A mismatch between input patterns and learning patterns was observed. WH complement input is more stable than that input, given the less variable complement-taking verbs provided by the student clinicians and the overtness of the WH word as a stable complementizer, which may have facilitated the identification and extraction of the target syntactic structure.

Adapting Curricula for Children With Language Comprehension Deficits.

PURPOSE: We will describe how a multisite research team adapted a language-focused curriculum to be used in a scale-up project. Specifically, we identified underlying principles to modify a Tier 1 whole-classroom language comprehension-focused curriculum to be used as a Tier 2 small-group curriculum with children identified as at risk for low language comprehension, including children with developmental language disorder (DLD). METHOD: We discuss how researchers used the following five guiding principles to adapt a curriculum for children at risk for low language comprehension, including children with DLD: (a) increased and ongoing professional development, (b) simplification of language input, (c) increased scaffolding, (d) attention to distributed practice, and (e) materials to support diversity and inclusion. RESULTS: We used these guiding principles to modify a popular language-based curriculum used in schools across the country. CONCLUSION: This clinical focus article showcases how guiding principles and frameworks for adaptation, within implementation science, can serve as a guidepost for speech-language pathologists and other educators who are adapting or scaling up a curriculum or intervention that was not designed for their target population.

Teaching little kids big sentences: A randomized controlled trial showing that children with DLD respond to complex syntax intervention embedded within the context of preschool/kindergarten science instruction.

BACKGROUND: The language of the science curriculum is complex, even in the early grades. To communicate their scientific observations, children must produce complex syntax, particularly complement clauses (e.g., I think it will float; We noticed that it vibrates). Complex syntax is often challenging for children with developmental language disorder (DLD), and thus their learning and communication of science may be compromised. AIMS: We asked whether recast therapy delivered in the context of a science curriculum led to gains in complement clause use and scientific content knowledge. To understand the efficacy of recast therapy, we compared changes in science and language knowledge in children who received treatment for complement clauses embedded in a first-grade science curriculum to two active control conditions (vocabulary + science, phonological awareness + science). METHODS & PROCEDURES: This 2-year single-site three-arm parallel randomized controlled trial was conducted in Delaware, USA. Children with DLD, not yet in first grade and with low accuracy on complement clauses, were eligible. Thirty-three 4-7-year-old children participated in the summers of 2018 and 2019 (2020 was cancelled due to COVID-19). We assigned participants to arms using 1:1:1 pseudo-random allocation (avoiding placing siblings together). The intervention consisted of 39 small-group sessions of recast therapy, robust vocabulary instruction or phonological awareness intervention during eight science units over 4 weeks, followed by two science units (1 week) taught without language intervention. Pre-/post-measures were collected 3 weeks before and after camp by unmasked assessors. OUTCOMES & RESULTS: Primary outcome measures were accuracy on a 20-item probe of complement clause production and performance on ten 10-item unit tests (eight science + language, two science only). Complete data were available for 31 children (10 grammar, 21 active control); two others were lost to follow-up. Both groups made similar gains on science unit tests for science + language content (pre versus post, d = 2.9, p < 0.0001; group, p = 0.24). The grammar group performed significantly better at post-test than the active control group (d = 2.5, p = 0.049) on complement clause probes and marginally better on science-only unit tests (d = 2.5, p = 0.051). CONCLUSIONS & IMPLICATIONS: Children with DLD can benefit from language intervention embedded in curricular content and learn both language and science targets taught simultaneously. Tentative findings suggest that treatment for grammar targets may improve academic outcomes. WHAT THIS PAPER ADDS: What is already known on the subject We know that recast therapy focused on morphology is effective but very time consuming. Treatment for complex syntax in young children has preliminary efficacy data available. Prior research provides mixed evidence as to children's ability to learn language targets in conjunction with other information. What this study adds This study provides additional data supporting the efficacy of intensive complex syntax recast therapy for children ages 4-7 with Developmental Language Disorder. It also provides data that children can learn language targets and science curricular content simultaneously. What are the clinical implications of this work? As SLPs, we have to talk about something to deliver language therapy; we should consider talking about curricular content. Recast therapy focused on syntactic frames is effective with young children.

Classification accuracy of the Quick Interactive Language Screener for preschool children with and without developmental language disorder.

INTRODUCTION: This research examined the classification accuracy of the Quick Interactive Language Screener (QUILS) for identifying preschool-aged children (3;0 to 6;9) with developmental language disorder (DLD). We present data from two independent samples that varied in prevalence and diagnostic reference standard. METHODS: Study 1 included a clinical sample of children (54 with DLD; 13 without) who completed the QUILS and a standardized assessment of expressive grammar (Syntax subtest from the Diagnostic Evaluation of Language Variation-Norm Referenced; Structured Photographic Expressive Language Test-Preschool 2nd Edition; or Structured Photographic Expressive Language Test-3 rd Edition). Study 2 included a community sample of children (25 with DLD; 101 without) who completed the QUILS and the Auditory Comprehension subtest of the Preschool Language Scales-5th Edition (PLS-5; Zimmerman et al., 2011). Discriminant analyses were conducted to compare classification accuracy (i.e., sensitivity and specificity) using the normreferenced cut score (< 25th percentile) with empirically derived cut scores. RESULTS: In Study 1, the QUILS led to low fail rates (i.e., high specificity) in children without impairment and statistically significant group differences as a function of children's clinical status; however, only 65% of children with DLD were accurately identified using the norm-referenced cutoff. In Study 2, 76% of children with DLD were accurately identified at the 25th percentile cutoff and accuracy improved to 84% when an empirically derived cutoff (<32nd percentile) was applied. CONCLUSIONS: Findings support the clinical application of the QUILS as a component of the screening process for identifying the presence or absence of DLD in community samples of preschool-aged children.

Building Sustainable Models of Research-Practice Partnerships Within Educational Systems.

PURPOSE: To describe the 9-year journey of a group of language and literacy researchers in establishing and cultivating Research-Practice Partnerships (RPPs). Those interested in incorporating implementation science frameworks in their research may benefit from reading our exploration into this type of work and our lessons learned. METHOD: We showcase how a group of researchers, who are committed to collaboration with school practitioners, navigated building and scaling RPPs within educational systems necessary for our long-term implementation work. We provide details and illustrative examples for three, distinct, mutually beneficial, and sustainable partnerships. RESULTS: Three different practice organizations are represented: (1) a single metropolitan school, (2) a small metropolitan school district, and (3) a large metropolitan school district, highlighting specific priorities and needs depending on the type of practice organization. Each partnership has distinct research and practice goals related to improving language and literacy outcomes in children. We describe how the researchers assisted with meeting the partner practice organizations' goals and engaged in capacity building while producing rigorous scientific knowledge to inform clinical and educational practice. Additionally, we discuss how research priorities and strategies were pivoted in the past year due to the COVID-19 pandemic, illustrating our commitment to the partnerships and how to respond to challenges to guarantee long-term sustainability. CONCLUSION: By discussing three distinctive partnerships, we demonstrate the various ways researchers can approach RPPs and grow them into mutually beneficial collaborations and support implementation goals.

Less Is More: Implementing the Minimal Intervention Needed for Change Approach to Increase Contextual Fit of Speech-Language Interventions.

PURPOSE: Speech-language pathologists (SLPs) and researchers face difficulties in moving evidence-based practices from clinical research into widespread practice, in part due to a mismatch between the design of typical intervention research studies and the realities of clinical settings. SLPs must adapt interventions from the literature or established programs to fit the needs of specific clients and settings. Researchers must design studies that better reflect clinical practice. METHOD: Here, we provide an overview of the Minimal Intervention Needed for Change (MINC) approach, a systematic approach to developing and adapting interventions that focuses on achieving meaningful outcomes within specific contexts. We outline the principles of MINC and illustrate this process through the use of a case study. RESULTS: MINC can support systematic development and adaptation of interventions in clinical and research settings, particularly settings with resource limitations. CONCLUSIONS: Researchers should work to align research intervention work with typical clinical settings. This involves both targeting outcomes that are functional and clinically significant and acknowledging resource limitations. SLPs should adapt evidence-based interventions systematically and carefully to meet the needs of clients and settings while retaining the core components of intervention that result in meaningful change for clients.

The Challenge of Rich Vocabulary Instruction for Children With Developmental Language Disorder.

Purpose The aims of the study were to explore responses of children with developmental language disorder (DLD) to rich vocabulary instruction and to identify potential factors that contribute to outcomes. Method Children with DLD participated in a language intervention embedded within a science camp. Using parent and clinician reports, standardized tests, probes, notes, and video, we derived descriptions of seven of the campers who received a vocabulary intervention that incorporated principles of rich instruction. We present them here as a case series. Results Five cases responded to the intervention with modest gains in Tier 2 science vocabulary and science knowledge. One case demonstrated no response, and another was unable to complete the intervention. The latter two cases presented with triple risks: DLD, executive function deficits, and stressors associated with poverty. In comparison, the best responder also lived in poverty and had DLD, but he had intact executive function, strengths in extant vocabulary, stronger knowledge of science, better engagement in the science and language intervention activities, and was older. Other factors that seemed to contribute to outcomes included the complexity of the word forms and dosage. Conclusions Translating research on rich instruction to clinical practice is challenging. This case series motivated hypotheses about the nature of the challenge and what to do about it, the primary one being that the modest success of rich vocabulary instruction for children with DLD is not a limitation of the approach itself but rather a reflection of the difficulty of delivering the intervention while tailoring the targets, approach, and dosage to the needs of individual children with DLD.

Complex Sentences in an Elementary Science Curriculum: A Research Note.

Purpose Elementary school students are expected to participate in science learning settings that place high demands on skill with certain types of grammatical structures, including complex sentences. This research note aims to clarify the types of complex sentences that are evident in a general education science curriculum across the elementary school years in order to assist clinicians and others in better understanding the specific language demands of science learning in the classroom. Method I analyzed all sentences within children's texts and suggested teacher scripting from the first-, third-, and fifth-grade science units of a commonly used general education curriculum aligned to the Next Generation Science Standards. We determined the frequency and type of complex sentences that were present for each type of material (text, teacher scripts) and grade level. Results Complex sentences are evident in both children's texts and suggested scripting provided to teachers at all grade levels. The rate of complex sentences in children's readings is higher in third- and fifth-grade texts than in first-grade texts. Complement clauses are common throughout, and adverbial and relative clauses are more frequent in third- and fifth-grade texts than in first-grade texts. Conclusions Children are expected to read and listen to complex sentences across the elementary school years. Speech-language pathologists should be aware of the language demands that general education science curricula may pose to students at different ages.

Use of Recast Intervention to Teach Causal Adverbials to Young Children With Developmental Language Disorder Within a Science Curriculum: A Single Case Design Study.

Purpose Language serves as an essential resource to learn about cause and effect throughout childhood. Causal adverbial sentences use causal conjunctions (e.g., because, so) to join 2 clauses to express cause-effect relationships ( Diessel & Hetterle, 2011 ). Causal adverbial sentences are frequently used to explain causal relationships in academic contexts, such as elementary school science and social studies classes ( Kinzie et al., 2014 ; J. Williams et al., 2014 ). Children with developmental language disorder (DLD) are at risk for failure in these academically relevant language skills. Here, we investigated the effect of language intervention focused on causal adverbials on both causal adverbials and acquisition of science content in young children with DLD. Method A multiple-probe design was used to examine the effect of language intervention using recasts on production of causal adverbials and acquisition of science content for 7 preschool/kindergarten children with DLD. Child production of causal adverbials and an untreated control structure were analyzed. Results Six of 7 participants exhibited gains in production of causal adverbials containing because, with effect sizes ranging from small to large. Performances on daily probes of science content learning and science unit tests indicate that participants are able to learn science content, but the magnitude of gains may not relate to skill in causal adverbial production. Conclusion Language intervention for young children with DLD can effectively treat complex syntactic targets such as causal adverbials in the context of science instruction, but it is unclear whether this can affect science content learning.

Using Propensity Score Matching to Address Clinical Questions: The Impact of Remote Microphone Systems on Language Outcomes in Children Who Are Hard of Hearing.

Purpose Children who are hard of hearing (CHH) have restricted access to acoustic and linguistic information. Increased audibility provided by hearing aids influences language outcomes, but the benefits of hearing aids are often limited by acoustic factors and distance. Remote microphone (RM) systems further increase auditory access by reducing the negative consequences of these factors. The purpose of this article was to identify factors that influence likelihood of RM system receipt and to investigate the effects of RM systems in home settings on later language outcomes. We used propensity score matching to compare language outcomes between children with and without access to personal RM systems in home settings. This article provides a description of how and why to perform propensity score-matching analyses with clinical populations. Method Participants were 132 CHH. Through parent report, we identified children who received RM systems for home use by 4 years of age. Logistic regression was used to determine factors that predict likelihood of RM system receipt in home settings. Propensity score matching was conducted on a subgroup of 104 participants. Performance on language measures at age 5 years was compared across propensity-matched children who did and did not receive RMs for personal use. Results Likelihood of RM receipt was associated with degree of hearing loss, maternal education, and location (recruitment site). Comparisons between matched pairs of children with and without RM systems in early childhood indicated significantly better discourse skills for children whose families owned RM systems, but no significant differences for vocabulary or morphosyntax. Conclusion Results provide preliminary evidence that the provision of personal RM systems for preschool-age CHH enhances higher-level language skills. The propensity score-matching technique enabled us to use an observational, longitudinal data set to examine a question of clinical interest.

Remote microphone systems for preschool-age children who are hard of hearing: access and utilization.

OBJECTIVES: Children who are hard of hearing (CHH) have restricted access to auditory-linguistic information. Remote-microphone (RM) systems reduce the negative consequences of limited auditory access. The purpose of this study was to characterise receipt and use of RM systems in young CHH in home and school settings. DESIGN: Through a combination of parent, teacher, and audiologist report, we identified children who received RM systems for home and/or school use by 4 years of age or younger. With cross-sectional surveys, parents estimated the amount of time the child used RM systems at home and school per day. STUDY SAMPLE: The participants included 217 CHH. RESULTS: Thirty-six percent of the children had personal RMs for home use and 50% had RM systems for school. Approximately, half of the parents reported that their children used RM systems for home use for 1-2 hours per use and RM systems for school use for 2-4 hours per day. CONCLUSIONS: Results indicated that the majority of the CHH in the current study did not receive RM systems for home use in early childhood, but half had access to RM technology in the educational setting. High-quality research studies are needed to determine ways in which RM systems benefit pre-school-age CHH.

Effects of a Complexity-Based Approach on Generalization of Past Tense -ed and Related Morphemes.

Purpose: In a previous article, we reported that beginning treatment for regular past tense -ed with certain types of verbs led to greater generalization in children with developmental language disorder than beginning treatment with other types of verbs. This article provides updated data from that study, including the addition of data from 3 children, results from naturalistic language samples, and data from a third time point. Method: Twenty 4- to 9-year-old children with developmental language disorder (10 per condition) were randomly assigned to receive language intervention in which the verbs used to teach regular past tense -ed were manipulated. Half received easy first intervention, beginning with highly frequent, telic, phonologically simple verbs, and half received hard first intervention, beginning with less frequent, atelic, and phonologically complex verbs. The design used a train-to-criterion approach, with children receiving up to 36 visits. Performance was assessed using elicited production probes and language samples before intervention, immediately following intervention and 6-8 weeks later. Results: Children in the hard first group showed greater gains on the use of regular past tense -ed in both structured probes (at immediate post only) and in language samples (at both immediate and delayed post). Gains attributable to therapy were not observed in untreated morphemes. Conclusions: This study suggests that the choice of therapy materials, with an eye on the role that treatment stimuli play in generalization, is important for treatment efficacy. Clinicians should consider early selection of atelic, lower-frequency, phonologically complex verbs when teaching children to use regular past tense -ed. Further work expanding this to other morphemes and a larger population is needed to confirm this finding.

Do the Hard Things First: A Randomized Controlled Trial Testing the Effects of Exemplar Selection on Generalization Following Therapy for Grammatical Morphology.

Purpose: Complexity-based approaches to treatment have been gaining popularity in domains such as phonology and aphasia but have not yet been tested in child morphological acquisition. In this study, we examined whether beginning treatment with easier-to-inflect (easy first) or harder-to-inflect (hard first) verbs led to greater progress in the production of regular past-tense -ed by children with developmental language disorder. Method: Eighteen children with developmental language disorder (ages 4-10) participated in a randomized controlled trial (easy first, N = 10, hard first, N = 8). Verbs were selected on the basis of frequency, phonological complexity, and telicity (i.e., the completedness of the event). Progress was measured by the duration of therapy, number of verb lists trained to criterion, and pre/post gains in accuracy for trained and untrained verbs on structured probes. Results: The hard-first group made greater gains in accuracy on both trained and untrained verbs but did not have fewer therapy visits or train to criterion on more verb lists than the easy-first group. Treatment fidelity, average recasts per session, and verbs learned did not differ across conditions. Conclusion: When targeting grammatical morphemes, it may be most efficient for clinicians to select harder rather than easier exemplars of the target.

Preschool Children's Memory for Word Forms Remains Stable Over Several Days, but Gradually Decreases after 6 Months.

Research on word learning has focused on children's ability to identify a target object when given the word form after a minimal number of exposures to novel word-object pairings. However, relatively little research has focused on children's ability to retrieve the word form when given the target object. The exceptions involve asking children to recall and produce forms, and children typically perform near floor on these measures. In the current study, 3- to 5-year-old children were administered a novel test of word form that allowed for recognition memory and manual responses. Specifically, when asked to label a previously trained object, children were given three forms to choose from: the target, a minimally different form, and a maximally different form. Children demonstrated memory for word forms at three post-training delays: 10 mins (short-term), 2-3 days (long-term), and 6 months to 1 year (very long-term). However, children performed worse at the very long-term delay than the other time points, and the length of the very long-term delay was negatively related to performance. When in error, children were no more likely to select the minimally different form than the maximally different form at all time points. Overall, these results suggest that children remember word forms that are linked to objects over extended post-training intervals, but that their memory for the forms gradually decreases over time without further exposures. Furthermore, memory traces for word forms do not become less phonologically specific over time; rather children either identify the correct form, or they perform at chance.

The efficacy of recasts in language intervention: a systematic review and meta-analysis.

PURPOSE: This systematic review and meta-analysis critically evaluated the research evidence on the effectiveness of conversational recasts in grammatical development for children with language impairments. METHOD: Two different but complementary reviews were conducted and then integrated. Systematic searches of the literature resulted in 35 articles for the systematic review. Studies that employed a wide variety of study designs were involved, but all examined interventions where recasts were the key component. The meta-analysis only included studies that allowed the calculation of effect sizes, but it did include package interventions in which recasts were a major part. Fourteen studies were included, 7 of which were also in the systematic review. Studies were grouped according to research phase and were rated for quality. RESULTS: Study quality and thus strength of evidence varied substantially. Nevertheless, across all phases, the vast majority of studies provided support for the use of recasts. Meta-analyses found average effect sizes of .96 for proximal measures and .76 for distal measures, reflecting a positive benefit of about 0.75 to 1.00 standard deviation. CONCLUSION: The available evidence is limited, but it is supportive of the use of recasts in grammatical intervention. Critical features of recasts in grammatical interventions are discussed.

Laughter and communicative engagement in interaction.

We examined if and how laughter functioned communicatively as an indicator of engagement in group interactions involving adults with traumatic brain injury (TBI). Engagement refers to the intensity and manner of interpersonal involvement displayed by participants in social situations, and it reflects the extent to which they are mutually engrossed in, and alive to, the unfolding interaction. Analysis revealed that laughter functioned communicatively to support the "face," or public self-image, of those with TBI and to foster rapport and social closeness. The distribution of laughables, or verbal and nonverbal behaviors that occasion laughter, between participants was also examined and compared with data collected by Simmons-Mackie and Schultz in their analysis of humor during traditional aphasia therapy. Results revealed that laughter and laughables are sensitive to how individuals engage one another in interaction. Implications are considered with respect to more recent models of intervention that seek to promote more discourse equality between participants.
