abstract: The current study analyzed existing data, collected under a previous U.S. Department of Education Reading First grant, to investigate the strength of the relationship between scores on the first- through third-grade Dynamic Indicators of Basic Early Literacy Skills - Oral Reading Fluency (DIBELS-ORF) test and scores on a reading comprehension test (TerraNova-Reading) administered at the conclusion of second- and third-grade. Participants were sixty-five English Language Learners (ELLs) learning to read in a school district adjacent to the U.S.-Mexico border. DIBELS-ORF and TerraNova-Reading scores were provided by the school district, which administers the assessments in accordance with state and federal mandates to monitor early literacy skill development. Bivariate correlation results indicate moderate-to-strong positive correlations between DIBELS-ORF scores and TerraNova-Reading performance that strengthened between grades one and three. Results suggest that the concurrent relationship between oral reading fluency scores and performance on standardized and high-stakes measures of reading comprehension may be different among ELLs as compared to non-ELLs during first- and second-grade. However, by third-grade the correlations approximate those reported in previous non-ELL studies. This study also examined whether the Peabody Picture Vocabulary Test (PPVT), a receptive vocabulary measure, could explain any additional variance on second- and third-grade TerraNova-Reading performance beyond that explained by the DIBELS-ORF. The PPVT was individually administered by researchers collecting data under a Reading First research grant prior to the current study. Receptive vocabulary was found to be a strong predictor of reading comprehension among ELLs, and largely overshadowed the predictive ability of the DIBELS-ORF during first-grade. Results suggest that receptive vocabulary scores, used in conjunction with the DIBELS-ORF, may be useful for identifying beginning ELL readers who are at risk for third-grade reading failure as early as first-grade. / Dissertation/Thesis / Ph.D. Educational Psychology 2011

The purpose of this study was to analyze the relationship between oral reading fluency (ORF) and Maze, two common Curriculum-Based Measures (CBMs), and the statewide large-scale assessment of reading in Oregon, the Oregon Assessment of Knowledge and Skills- Reading (OAKS-R). A sample of three cohorts of eighth-grade students in an Oregon school district was used to examine concurrent validity, predictive validity, and the relation between demographic characteristics, disability status, and socio-economic status and the ability to predict performance on the OAKS-R. Findings of the concurrent validity analysis revealed a moderately strong positive correlation between the OAKS-R and both ORF and Maze measures, with ORF demonstrating a slightly stronger correlation with the OAKS-R. Multiple regression analyses were used to analyze the predictive relationship between ORF and Maze and scores on the eighth-grade OAKS-R. Both ORF and Maze were statistically significant predictors of OAKS-R, demonstrating moderately positive relationships with scores on the state reading test. Although no interaction effect was found between disability classification or eligibility for free or reduced-price meals and the different CBMs, in relation to the OAKS-R, student disability status was negatively related to performance on the OAKS-R. The relationship between OAKS-R performance and low socio-economic status, as measured by eligibility for free or reduced-price lunch status, was not consistent across the cohorts. This finding is promising, as it indicates that there may be factors that schools can take advantage of to ameliorate the relationship between poverty and reading outcome measures for eighth-grade students. In light of study results, suggestions for future research, as well as implications for the field, are discussed. This study adds to the research literature documenting that ORF and Maze assessments provide schools with valuable information to predict student performance on statewide large-scale assessments of reading. With CBM data available early in the school year, schools can provide additional intervention as needed, potentially leading to improved end-of-year student performance on the OAKS-R.

The complexity of text has a number of implications for educators in the areas of instruction and assessment. Text complexity is particularly important in formative assessments, which utilize repeated, alternate, equivalent forms to capture student growth towards a general outcome. A key assumption of such tools is that alternate forms of the assessment are of equal complexity. Consequently, there is a need to better understand what variables contribute to text complexity and how they impact student performance. This study was designed to evaluate features of text that are not typically included in readability estimates but may contribute to the text complexity: text cohesion and genre. Currently, text complexity of oral reading fluency measures is often quantified using readability estimates. It is hypothesized that a factor generally excluded from readability estimates, text cohesion&mdashthe extent to which the text functions as a cohesive, meaningful whole&mdashcontributes to text variability and variability in student performance. This research evaluated the role of a type of text cohesion (referential cohesion) in text complexity by manipulating the cohesion of passages otherwise assumed to be of equal difficulty. Genre was also considered, as research suggests that genre may impact complexity ratings of texts. Passages were strategically selecting to capture four conditions&mdash1) informational text/low cohesion, 2) informational text/high cohesion, 3) narrative text/low cohesion, and 4) narrative text/high cohesion. Data were collected on reading rate, accuracy, and passage-specific reading comprehension Results were analyzed using two-way, univariate ANOVA with dependent observations. Results indicate effects for each of the dependent variables included in the design. For rate and accuracy, results indicate significant interactions between genre and referential cohesion; scores were significantly higher for high cohesion narrative text than low cohesion narrative text and high cohesion informational text. There was a significant main effect of genre on comprehension, with students performing significantly better on the comprehension measure for narrative texts than informational texts. Altogether, these results indicate direct effects of genre and referential cohesion on student reading performance and provide evidence that text cohesion may be a meaningful component of text complexity. / 2015-10-10

A fala espontânea, também nomeada como discurso espontâneo, compõe a investigação de várias pesquisas nas áreas da fonética e da fonologia. Pesquisas relevantes na área podem ser observadas no Journal of the International Phonetic Association (JIPA), referência base para a nossa pesquisa e publicação onde constam estudos que investigam diferentes línguas nos aspectos fonético- acústicos da fala espontânea. O objetivo geral desta pesquisa é investigar aspectos fonético-acústicos da fala espontânea no português do Brasil e comparar a leitura oral tendo como justificativa principal o desafio que este estudo propõe diante da escassez de pesquisas em relação à fala espontânea com o português do Brasil. Nossas hipóteses basearam-se em estudos de alguns autores que estudaram a fala espontânea em diferentes línguas, como Barry e Andreeva; Shriberg (2001) e que chegaram a algumas definições para fala espontânea. Segundo esses autores, a fala espontânea se opõe ao discurso lido por ser uma fala despreparada e não treinada, além de apresentar duração de discurso mais longa e maior ocorrência de disfluência do que a leitura oral. Barry e Andreeva (2001) destacam também mudanças na prosódia, já que a função das palavras é diferente em cada uma dessas modalidades de fala. A partir destes trabalhos, surge o objetivo específico da pesquisa: verificar os aspectos estudados nos trabalhos acima citados no português do Brasil e caracterizar cada modalidade de fala (fala espontânea e a leitura oral) por meio da identificação de possíveis similaridades ou possíveis diferenças nos aspectos de: duração das frases, pausas (duração e número de ocorrências), freqüência fundamental (F0 inicial e F0 final e F0 máxima e F0 mínima) e medidas de Voice Onset Time (VOT) de consoantes oclusivas surdas. A coleta das amostras de fala espontânea e de leitura oral foi realizada a partir da observação dos métodos sugeridos por Local e Walker (2005) e da aplicação de provas semi-dirigidas por meio da gravação de diálogos quase-espontâneos, observadas em Nicolaidis (2001) e Andreeva e Barry (2001) em pesquisas com a fala espontânea. O corpus constitui a participação de quatro homens com idade média de trinta e seis anos. Os critérios para a seleção dos sujeitos foram: sujeitos do sexo masculino, falantes do português do Brasil, monolíngues, com nível superior (completo ou incompleto), bons leitores, não profissionais da voz, sem queixa e/ou alteração de fala e voz e que não fizessem uso de drogas. Na pesquisa consta a avaliação de 48 (quarenta e oito) frases de todos os sujeitos, sendo 12 (doze) de cada sujeito, 6 (seis) frases de fala espontânea e 6 (seis) de leitura oral do mesmo texto. Além destes dados, para as medidas de Voice Onset Time VOT, foram realizadas medidas de 60 (sessenta) consoantes oclusivas surdas, 10 (dez) de cada tipo de oclusiva (velar, alveolar e bilabial, com medidas na modalidade espontânea e na versão lida. As consoantes oclusivas analisadas foram retiradas das frases selecionadas e também colhidas de forma aleatória de outras frases do discurso. O programa para gravação e medidas acústicas foi o Winpitch Prow 1.0. Os resultados mostraram algumas particularidades de cada tipo de fala, porém vale ressaltar os aspectos obtivemos dados com significância estatística: maior ocorrência e durações mais longas de pausas na fala espontânea, F0 inicial mais alta do que e F0 final na leitura oral, F0 final mais alta em fala espontânea e medidas de VOT mais longas em leitura oral. / Spontaneous speech, also known as spontaneous speech constitutes the investigation of research in the fields of Phonetics and Phonology. The relevant research in the field has been published in the Journal of the International Phonetic Association (JIPA) and is reference of our research. The main objective of this study is to investigate the phonetic acoustic aspects of Brazilian Portuguese speech and to compare it to oral reading. The major challenge of this study is the lack of research related to the spontaneous speech in Brazilian Portuguese language. Our hypothesizes are based on the works of some authors who have studied the spontaneous speech in different languages. Barry, Andreeva and Shriberg (2001) and developed some definitions of spontaneous speech. According to these authors, spontaneous speech is much different than oral reading because it is unprepared and unrehearsed. Spontaneous speech typically results in a longer discourse duration and has a greater occurrence of disfluency than oral reading. Barry and Andreeva(2001), also studied the prosody changes, since the function of words is different in each of these speech modalities. From these studies is born the specific objective of this research; to examine the aspects studied in the research above as it relates to Brazilian Portuguese and to characterize each speech modality (spontaneous speech and oral reading) through the identification of possible similarities or possible differences in the following aspects: duration of the sentences, pauses (duration and number of occurrences), fundamental frequencies (F0 initial and F0 final and F0 maximum and F0 minimum) and Voice Onset Time (VOT) measurements of unvoiced occlusive consonants. The collection of spontaneous speech and oral reading samples was carried out through the observation of methods suggested by Local and Walker (2005) and the application of semi-directed proofs, through the record of nearly spontaneous dialogs, observed by Nicolaidis (2001), Andreeva and Barry(2001) in their research on spontaneous speech. The corpus was conducted with the participation of four men all 36 years old. The criteria used to select the subjects were that they be male individuals; Brazilian, monolingual, Portuguese speakers; graduation (complete or incomplete); good readers; amateur speakers; have no speech or voice alteration and non drug users. The study consists of the valuation of 48 sentences in total. Twelve sentences from each individual consisting of six spontaneous sentences and six oral readings of the same texts. In conjunction with these data Voice Onset Time measurements - Vot, were carried out in measurements of 60 unvoiced occlusive consonants, 10 of each kind of occlusive (velar, alveolar, and bilabial) along with measurements in the spontaneous modality and reading versions. The occlusive consonants analyzed were obtained from the selected sentences and also obtained in an aleatory way from another sentences of the discourse. The program used to record and acoustic measurements was Winpitch Prow 1.0. The results show some particularities of each kind of speech. It is striking we obtained significant the results aspects : pauses bigger (duration and number of occurrences) in the spontaneous speech, F0 initial increase than F0 final of the oral reading; F0 final increase in spontaneous speech and VOT measurements of longer duration than occurred in the oral readings.

This study investigated oral reading fluency development among Hispanic high school English-language learners. Participants included 11 males and 9 females from first-year, second-year, and third-year English language arts classes. The pre-post experimental study, which was conducted during a four-week ESL summer program, included a treatment and a control group. The treatment group received a combination of components, including modified repeated reading with self-voice listening and oral dictation output from a speech recognition program. Each day, students performed a series of tasks, including dictation of part of the previous day’s passage; listening to and silently reading a new passage; dictating and correcting individual sentences from the new passage in the speech recognition environment; dictating the new passage as a whole without making corrections; and finally, listening to their own voice from their recorded dictation. This sequence was repeated in the subsequent sessions. Thus, this intervention was a technology-enhanced variation of repeated reading with a pronunciation dictation segment. Research questions focused on improvements in oral reading accuracy and rate, facility with the application, student perceptions toward the technology for reading, and the reliability of the speech recognition program. The treatment group improved oral reading accuracy by 50%, retained and transferred pronunciation of 55% of new vocabulary, and increased oral reading rate 16 words-correct-per-minute. Students used the intervention independently after three sessions. This independence may have contributed to students’ self-efficacy as they perceived improvements in their pronunciation, reading in general, and reported an increased liking of school. Students initially had a very positive perception toward using the technology for reading, but this perception decreased over the four weeks from 2.7 to 2.4 on a 3 point scale. The speech recognition program was reliable 94% of the time. The combination of the summer school program and intervention component stacking supported students’ gains in oral reading fluency, suggesting that further study into applications of the intervention is warranted. Acceleration of oral reading skills and vocabulary acquisition for ELLs contributes to closing the reading gap between ELLs and native-English speakers. Fluent oral reading is strongly correlated with reading comprehension, and reading comprehension is essential for ELLs to be successful in school. Literacy support tools such as this intervention can play a role in ameliorating English acquisition faster than the rate attained through traditional practices.
