Description
The purpose of this single case design study was to examine the efficacy of a graphic organizer for improving the reading comprehension of middle school Spanish-English bilingual middle school students with learning disabilities. Students included two females and one male student. Using a multiple baseline across participants design, students were taught to create a funnel map graphic organizer for 10 descriptive text passages. Students’ performance was assessed on their ability to correctly create the funnel map (criterion variable) and to comprehend the expository passages during baseline, intervention, and maintenance phases. Each participant learned to create an accurate funnel map for descriptive texts within four sessions. Reading comprehension scores began to increase within three intervention sessions for each participant. Results showed the positive effect of using the funnel map to improve reading comprehension of descriptive texts. Individual TAU effect sizes (.81 to .92) and overall TAU-U effect sizes (.86) and a Between Cases Standardized Mean Difference (BC-SMD) of 1.87 showed the intervention to be highly effective. Based on the effect sizes, the funnel map was effective for improving the reading comprehension of middle school Spanish-English bilingual students with learning disabilities.

Description
Speech sound disorders (SSDs) are the most prevalent type of communication disorder in children. Clinically, speech-language pathologists (SLPs) rely on behavioral methods for assessing and treating SSDs. Though clients typically experience improved speech outcomes as a result of therapy, there is evidence that underlying deficits may persist even in individuals who have completed treatment for surface-level speech behaviors. Advances in the field of genetics have created the opportunity to investigate the contribution of genes to human communication. Due to the heterogeneity of many communication disorders, the manner in which specific genetic changes influence neural mechanisms, and thereby behavioral phenotypes, remains largely unknown. The purpose of this study was to identify genotype-phenotype associations, along with perceptual, and motor-related biomarkers within families displaying SSDs. Five parent-child trios participated in genetic testing, and five families participated in a combination of genetic and behavioral testing to help elucidate biomarkers related to SSDs. All of the affected individuals had a history of childhood apraxia of speech (CAS) except for one family that displayed a phonological disorder. Genetic investigation yielded several genes of interest relevant for an SSD phenotype: CNTNAP2, CYFIP1, GPR56, HERC1, KIAA0556, LAMA5, LAMB1, MDGA2, MECP2, NBEA, SHANK3, TENM3, and ZNF142. All of these genes showed at least some expression in the developing brain. Gene ontology analysis yielded terms supporting a genetic influence on central nervous system development. Behavioral testing revealed evidence of a sequential processing biomarker for all individuals with CAS, with many showing deficits in sequential motor skills in addition to speech deficits. In some families, participants also showed evidence of a co-occurring perceptual processing biomarker. The family displaying a phonological phenotype showed milder sequential processing deficits compared to CAS families. Overall, this study supports the presence of a sequential processing biomarker for CAS and shows that relevant genes of interest may be influencing a CAS phenotype via sequential processing. Knowledge of these biomarkers can help strengthen precision of clinical assessment and motivate development of novel interventions for individuals with SSDs.

Description
How hard should the books be in elementary small-group reading? This study explored text difficulty for bilingual students reading below grade level in third grade. Using a convergent parallel mixed methods design, I used qualitative methods to analyze students’ engagement and discussion during small groups and single case design to evaluate students’ fluency and reading comprehension after reading and discussing texts in small groups.
Six Spanish-English bilingual students, split into two groups of three, participated in twelve, 30-minute, small-group reading sessions. Students in Group 1 read approximately one year below grade level, and students in Group 2 read approximately a year and a half below grade level. In six of the twelve sessions, students read and discussed texts matched to their reading levels, and in the other six they read and discussed texts one year ahead of their reading levels. I assigned matched and difficult texts across the twelve days by blocked randomization.
I analyzed video transcripts of each session to understand students’ engagement (focus of engagement, strategies, and interaction) and discussion (inferential vs. literal responses, instances of verbal participation). At the end of each session, students reread and retold the book the group had read and discussed that day to produce a fluency (words correct per minute) and comprehension (ideas correctly retold) score.
Findings were complex and revealed that different levels of texts have both advantages and drawbacks. Key findings included: For fluency, half of the students benefited from matched texts. The other half read difficult texts with similar fluency to matched texts. For comprehension, text difficulty did not matter for anyone except one student, and for him it only had an effect on 3 of 12 days. Group 2 engaged much more with texts and ideas in difficult books and with pictures in matched books. Group 1 had more inferential/interpretive responses with matched texts, and Group 2 had more inferential and interpretive responses with difficult texts. Most students participated evenly regardless of the difficulty of the text under discussion. However, two students talked more when discussing matched texts.
