Description
Frequency effects favoring high print-frequency words have been observed in frequency judgment memory tasks. Healthy young adults performed frequency judgment tasks; one group performed a single task while another group did the same task while alternating their attention to a secondary task (mathematical equations). Performance was assessed by correct and error responses, reaction times, and accuracy. Accuracy and reaction times were analyzed in terms of memory load (task condition), number of repetitions, effect of high vs. low print-frequency, and correlations with working memory span. Multinomial tree analyses were also completed to investigate source vs. item memory and revealed a mirror effect in episodic memory experiments (source memory), but a frequency advantage in span tasks (item memory). Interestingly enough, we did not observe an advantage for high working memory span individuals in frequency judgments, even when participants split their attention during the dual task (similar to a complex span task). However, we concluded that both the amount of attentional resources allocated and prior experience with an item affect how it is stored in memory.

Description
Everyday speech communication typically takes place face-to-face. Accordingly, the task of perceiving speech is a multisensory phenomenon involving both auditory and visual information. The current investigation examines how visual information influences recognition of dysarthric speech. It also explores where the influence of visual information is dependent upon age. Forty adults participated in the study that measured intelligibility (percent words correct) of dysarthric speech in auditory versus audiovisual conditions. Participants were then separated into two groups: older adults (age range 47 to 68) and young adults (age range 19 to 36) to examine the influence of age. Findings revealed that all participants, regardless of age, improved their ability to recognize dysarthric speech when visual speech was added to the auditory signal. The magnitude of this benefit, however, was greater for older adults when compared with younger adults. These results inform our understanding of how visual speech information influences understanding of dysarthric speech.

Description
Language and music are fundamentally entwined within human culture. The two domains share similar properties including rhythm, acoustic complexity, and hierarchical structure. Although language and music have commonalities, abilities in these two domains have been found to dissociate after brain damage, leaving unanswered questions about their interconnectedness, including can one domain support the other when damage occurs? Evidence supporting this question exists for speech production. Musical pitch and rhythm are employed in Melodic Intonation Therapy to improve expressive language recovery, but little is known about the effects of music on the recovery of speech perception and receptive language. This research is one of the first to address the effects of music on speech perception. Two groups of participants, an older adult group (n=24; M = 71.63 yrs) and a younger adult group (n=50; M = 21.88 yrs) took part in the study. A native female speaker of Standard American English created four different types of stimuli including pseudoword sentences of normal speech, simultaneous music-speech, rhythmic speech, and music-primed speech. The stimuli were presented binaurally and participants were instructed to repeat what they heard following a 15 second time delay. Results were analyzed using standard parametric techniques. It was found that musical priming of speech, but not simultaneous synchronized music and speech, facilitated speech perception in both the younger adult and older adult groups. This effect may be driven by rhythmic information. The younger adults outperformed the older adults in all conditions. The speech perception task relied heavily on working memory, and there is a known working memory decline associated with aging. Thus, participants completed a working memory task to be used as a covariate in analyses of differences across stimulus types and age groups. Working memory ability was found to correlate with speech perception performance, but that the age-related performance differences are still significant once working memory differences are taken into account. These results provide new avenues for facilitating speech perception in stroke patients and sheds light upon the underlying mechanisms of Melodic Intonation Therapy for speech production.

Description
The current study employs item difficulty modeling procedures to evaluate the feasibility of potential generative item features for nonword repetition. Specifically, the extent to which the manipulated item features affect the theoretical mechanisms that underlie nonword repetition accuracy was estimated. Generative item features were based on the phonological loop component of Baddelely's model of working memory which addresses phonological short-term memory (Baddeley, 2000, 2003; Baddeley & Hitch, 1974). Using researcher developed software, nonwords were generated to adhere to the phonological constraints of Spanish. Thirty-six nonwords were chosen based on the set item features identified by the proposed cognitive processing model. Using a planned missing data design, two-hundred fifteen Spanish-English bilingual children were administered 24 of the 36 generated nonwords. Multiple regression and explanatory item response modeling techniques (e.g., linear logistic test model, LLTM; Fischer, 1973) were used to estimate the impact of item features on item difficulty. The final LLTM included three item radicals and two item incidentals. Results indicated that the LLTM predicted item difficulties were highly correlated with the Rasch item difficulties (r = .89) and accounted for a substantial amount of the variance in item difficulty (R2 = .79). The findings are discussed in terms of validity evidence in support of using the phonological loop component of Baddeley's model (2000) as a cognitive processing model for nonword repetition items and the feasibility of using the proposed radical structure as an item blueprint for the future generation of nonword repetition items.

Description
The purpose of this study was to explore and report on the impact of coaching as an embedded part of professional development has on teacher learning and practice in the context of educating English Language Learners (ELLs). A close examination was made of what teachers, coaches and principals believe to be effective professional development and how the relationship between a coach and teacher affects understanding of and classroom practice with a specific population of students. The research questions were (a) How can coaching support implementation of professional development goals over traditional development activities as reported by the teacher, coach and administrator? (b) What is the relationship between the coach and teacher? (c) How does the coaching process relate to self- reported coach and teacher knowledge of instruction and practice in the ELL context? I used a qualitative approach to gather data through classroom observations and in-depth interviews. The 17 participants came from Title 1 elementary schools with high ELL populations located in the central and west valley of Phoenix, Arizona. I analyzed the data deductively then coded and categorized participant responses in relation to the literature on professional development and coaching. The findings indicated that those involved perceived embedded coaching as an effective component of professional development. What I have now termed based on my study as Professional Development Praxis (PPD). They agreed that with a structured system of coaching in place, both teachers and coaches increased their knowledge of how to best instruct ELLs as well as enhanced their ability to put research-based strategies into classroom practice. The recommendation of this study is that districts, schools and professional developers provide training and support for educators in a meaningful, effective and student centered way. Professional development were educators are provided knowledge about ELLs, opportunities for practice of what they are learning in and out of training sessions and on-going collaboration and support as they work with their students. It is the job of everyone involved in the system to better prepare educators to meet the critical needs of students who come to school with specific linguistic and academic needs.

Effective professional development has been shown to improve instruction and increase student academic achievement. The Train the Trainer professional development model is often chosen by the state Department of Education for its efficiency and cost effectiveness of delivering training to schools and districts widely distributed throughout the state. This is a study of the Train the Trainer component of an innovative K12 professional development model designed to meet the needs of the state's lowest performing schools that served some of the state's most marginalized students. Pursuing a Vygotzkian social constructivist framework, the model was developed and informed by its stakeholders, providing training that was collaborative, job-embedded, ongoing, and continuously adapted to meet the needs of the School Improvement Grant participants. Schools in the multi-case study were awarded the federal ARRA School Improvement Grant in 2010. Focus questions include: What influence does the Train the Trainer component have on classroom instruction specifically as it relates to formative assessment? and To what extent does the trainer support the implementation of the Train the Trainer professional development at the classroom level? The action research study took place from August 2011 to February 2012 and used a mixed-methods research design.

Description
Identification of primary language impairment (PLI) in sequential bilingual children is challenging because of the interaction between PLI and second language (L2) proficiency. An important step in improving the accurate diagnosis of PLI in bilingual children is to investigate how differences in L2 performance are affected by a length of L2 exposure and how L2 assessment contributes to differentiation between children with and without PLI at different L2 proficiency levels. Sixty one children with typical language development (TD) ages 5;3-8 years and 12 children with PLI ages 5;5-7;8 years participated. Results revealed that bilingual children with and without PLI, who had between 1 and 3 years of L2 exposure, did not differ in mean length of utterance (MLU), number of different words, percent of maze words, and performance on expressive and receptive grammatical tasks in L2. Performance on a grammaticality judgment task by children with and without PLI demonstrated the largest effect size, indicating that it may potentially contribute to identification of PLI in bilingual populations. In addition, children with PLI did not demonstrate any association between the length of exposure and L2 proficiency, suggesting that they do not develop their L2 proficiency in relation to length of exposure in the same manner as children with TD. Results also indicated that comprehension of grammatical structures and expressive grammatical task in L2 may contribute to differentiation between the language ability groups at the low and intermediate-high proficiency levels. The discriminant analysis with the entire sample of bilingual children with and without PLI revealed that among L2 measures, only MLU contributed to the discrimination between the language ability groups. However, poor classification accuracy suggested that MLU alone is not a sufficient predictor of PLI. There were significant differences among L2 proficiency levels in children with TD in MLU, number of different words, and performance on the expressive and receptive grammatical tasks in L2, indicating that L2 proficiency level may potentially impact the differentiation between language difficulties due to typical L2 acquisition processes and PLI.

ABSTRACT
This study investigated the effects of a family literacy program for Latino parents' language practices at home and their children's oral language skills. Specifically, the study examined the extent to which: (a) the program called Family Reading Intervention for Language and Literacy in Spanish (FRILLS) was effective at teaching low-education, low-income Latino parents three language strategies (i.e., comments, high-level questions and recasts) as measured by parent implementation, (b) parents maintained implementation of the three language strategies two weeks following the program, and (c) parent implementation of such practices positively impacted children's oral language skills as measured by number of inferences, conversational turns, number of different words, and the Mean Length of Utterance in words (MLU-w).
Five Latino mothers and their Spanish-speaking preschool children participated in a multiple baseline single-subject design across participants. After stable baseline data, each mother was randomly selected to initiate the intervention. Program initiation was staggered across the five mothers. The mothers engaged in seven individual intervention sessions. Data on parent and child outcomes were collected across three experimental conditions: baseline, intervention, and follow-up. This study employed visual analysis of the data to determine the program effects on parent and child outcome variables.
Results indicated that the program was effective in increasing the mothers' use of comments and high-level questions, but not recasts, when reading to their children. The program had a positive effect on the children's number of inferences, different words, and conversational turns, but not on the mean length of utterances. Findings indicate that FRILLS may be effective at extending and enriching the language environment that low-income children who are culturally and linguistically diverse experience at home. Three results with important implications for those who implement, develop, or examine family literacy programs are discussed.

ABSTRACT
This mixed methods study examined how a high-poverty urban school district implemented four initiatives to support special education teachers and increase student achievement. The initiatives that were implemented consisted of direct instruction teaching methods, the use of a district-approved curriculum, monitoring program fidelity with walkthroughs, and increased professional development opportunities.
Quantitatively, the study compared walkthrough data and student achievement scores. The walkthrough data was collected from 52 special education teachers employed at the 19 schools making up the district while teaching reading and math. Student achievement scores were collected from the students taught by the 52 special education teachers. The walkthrough data compared the percentage of students making academic growth on district assessments with the percentage of teachers implementing the district initiatives with a high level of fidelity. Data was collected and analyzed between the first and third quarters of the 2013–2014 school year.
Qualitatively, six special education teachers were interviewed to examine their thoughts on the change process and to determine their needs to be successful as they continued to implement the district initiatives.
The results of the quantitative data indicated that students demonstrated growth as walkthrough scores increased in 16 out of 19 schools, specifically in the area of math. Fidelity to the initiatives increased throughout the year as teachers began to use and implement the initiatives.
The results of the qualitative data indicated that special education teachers positively responded to the support they received through the Special Services
ii
Department and the district’s initiatives. Using grounded theory, it was determined that teachers need opportunities for collaboration, feedback, and time to practice in order to be successful.
Lastly, the epilogue discusses the next steps that are being taken by the district to support all students with their learning needs.

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.
