Effects of variation in teacher organization on classroom functioning

This study examined effects of variation in teacher organization on how time is spent in classrooms, focusing on time spent in transitions and instruction, including child skill by teacher organization interactions. Forty-four first-grade classrooms were observed three times over the school year. Timed narratives of each activity were recorded. “Orient-organize” referred to time teachers spent orienting students to classroom procedures or organizing the class for specific assignments, and included instructional clarity, where teachers described objectives of activities to students. Using hierarchical linear modeling, substantial variation across teachers in orient-organize was observed. Overall, classrooms spent less time in organization as the school year progressed. In addition, spending more time in organization was related to less time spent in transition. Students in classrooms that spent more time in organization in the fall also experienced greater amounts of time in child-managed activities in the spring. There was also an interaction between child vocabulary and amount of orient-organize in the winter. Students with lower vocabulary scores were more likely to be in classrooms that spent more time in spring child-managed activities if they continued to receive substantial amounts of orient-organize in the winter. The opposite was the case for students with high vocabulary skills.     

Examining the core: Relations among reading curricula, poverty, and first through third grade reading achievement

Policy changes at the federal and state level are endeavoring to improve student achievement at schools serving children from lower-SES homes. One important strategy is the focus on using evidence-based core reading curricula to provide a consistent framework for instruction across schools. However, rarely have these curricula undergone rigorous comparative testing. Therefore, the purpose of this study was to compare the effects of six core reading curricula on oral reading fluency growth, while appraising whether these effects differ by grade level and for children living in lower socioeconomic (SES) households. Over 30,000 students in first through third grade Florida Reading First classrooms comprise this academically and economically diverse cross-sectional. Hierarchical Linear Modeling was used to model latent growth curves for students' reading fluency scores over the school year. Growth curves revealed differences across curricula as well as between students of lower and higher SES, suggesting that reading fluency growth trajectories for curricula varied depending on student SES and grade level. Findings indicate that while there are similarities among curricula, they sometimes differ in their ability to promote reading skill growth. Differences by grade level and SES were also detected. However, many of these differences were small. Implications for the use of curriculum as a conduit for improving reading instruction are discussed.     

School profiles of at-risk student concentration: Differential growth in oral reading fluency

The present study provides a data-driven approach to identifying groups of schools based on the concentration of at-risk students the school serves. The percentage of English language learners, minority students, and students eligible for free or reduced priced lunch were used as indicators in a latent profile analysis of 569 schools. The goal of the present study was to determine whether school-level average student reading performance varied as a function of the groups identified in the latent profile analysis. To do so, groups extracted by the latent profile analysis were used as school-level predictors of growth in oral reading fluency, which was modeled at the within-student level of a three-level hierarchical growth curve model. Oral reading fluency was measured at four points during the year in a large cross-sectional sample of first-, second-, and third-grade students. Results indicated that schools were able to be classified into four distinct groups based on their concentrations and types of at-risk students. Further, in all three grades, there were significant differences between the four identified groups observed in average reading fluency scores at the beginning of the year, the end of the year, and growth during the year indicating that groups based on school-concentration of at-risk students were significantly related to average student achievement in reading ability.     

Teaching practices and the promotion of achievement and adjustment in first grade

The effects of teacher practices in promoting student academic achievement, behavioral adjustment, and feelings of competence were investigated in a prospective study of 257 children in 14 first grade classrooms. Using hierarchical linear modeling and regression techniques, observed teaching practices in the fall were explored as predictors of mean levels of student achievement, behavior, and self-perceived competence, as well as the percentage of students who met academic standards as measured in the spring. After controlling for child characteristics at school entry, in classrooms where teachers were observed to offer more instructional and social-emotional support (i.e., attending to students' interest and initiative, providing appropriately challenging learning opportunities, and creating positive social relationships), children on average acquired more math skills, made greater behavioral gains, and had more positive perceptions of their academic abilities. Further, a higher percentage of students in such classrooms met academic standards (two reading, one math). Implications for future research and educational practice are discussed.     

The quality of teacher-student interactions: associations with first graders' academic and behavioral outcomes

The associations between the quality of teacher-student interactions and first grade academic and adaptive behavior outcomes were examined in a study of 106 Portuguese students in 64 first grade classrooms. Students' vocabulary, print concepts, math, and adaptive skills were assessed both at the end of preschool and in first grade. Classrooms were observed in the spring of first grade. After taking into account family risk factors and preschool skills, the quality of teacher-student interactions, particularly in terms of classroom organization, was positively associated with students' first grade vocabulary and print concepts. In addition, classroom quality predicted number identification outcomes differently depending on student skills prior to school entry. Students with lower preschool math skills seemed to benefit from higher quality teacher-student interactions. These findings provide further support for the unique contribution of the quality of teacher-student interactions in first grade and suggest that it may be an important mechanism to improve academic skills.     

Teacher qualifications, classroom practices, family characteristics, and preschool experience: Complex effects on first graders' vocabulary and early reading outcomes

Using an ecological model, this study explored the effects of distal and proximal sources of influence on students' learning. We first examined three markers of teacher qualification — elementary education credential, years of education, and years of experience — on observed classroom practices across three dimensions — warmth/responsivity, control/discipline, and time spent on academic activities — as they related to children's vocabulary and early reading skills. We then examined the impact of this core system embedded in a larger system that included children's vocabulary and word recognition skills prior to school entry, their home and preschool learning environments, and family SES. Results, using structural equation modeling, revealed that students whose teachers were more warm and responsive and who spent more time in academic activities demonstrated stronger vocabulary and decoding skills at the end of first grade. Teachers with more years of education interacted with students more responsively but, surprisingly, their students had weaker early reading skills. Overall, students' language and letter-word recognition scores when they were 54 months of age, their home learning environment and family SES accounted for most of the variability in vocabulary and early reading scores at the end of first grade. Implications of the multiple and concurrent sources of influence on students' language and literacy development are discussed.     

Class size effects on literacy skills and literacy interest in first grade: A large-scale investigation

This article examines the impact of class size on literacy skills and on literacy interest in beginning readers from zones with specific educational needs in France. The data came from an experiment involving first graders in which teachers and pupils were randomly assigned to the different class types (small classes of 10-12 pupils vs. regular classes of 20-25 pupils).Globally, the findings reveal that class size has a (small) impact on the two basic literacy skills, reading (word recognition task) and spelling (word production task). Children with high literacy interest made more progress than children with low literacy interest. The analysis also explores the effect of four factors - early schooling, age, first language and socio-economic status - on the same type of literacy skills as above. Smaller classes most specifically improved performances in two types of population: children whose first language is French and children from intermediate and average socio-economic brackets. This means, in contrast, that neither the children from the most disadvantaged backgrounds nor the children whose first language was not French benefited from the use of smaller first grade classes. Data in this experiment are examined in the light of studies on the connections between class size, classroom procedures and pupils' engagement.

The use of probabilistic lexicality cues for word segmentation in Chinese reading

In an eye-tracking experiment we examined whether Chinese readers were sensitive to information concerning how often a Chinese character appears as a single-character word versus the first character in a two-character word, and whether readers use this information to segment words and adjust the amount of parafoveal processing of subsequent characters during reading. Participants read sentences containing a two-character target word with its first character more or less likely to be a single-character word. The boundary paradigm was used. The boundary appeared between the first character and the second character of the target word, and we manipulated whether readers saw an identity or a pseudocharacter preview of the second character of the target. Linear mixed-effects models revealed reduced preview benefit from the second character when the first character was more likely to be a single-character word. This suggests that Chinese readers use probabilistic combinatorial information about the likelihood of a Chinese character being single-character word or a two-character word online to modulate the extent of parafoveal processing.     

Reading First kindergarten classroom instruction and students' growth in phonological awareness and letter naming–decoding fluency

This study investigated the role of the amount, content, and implementation of reading instruction provided by 17 kindergarten teachers in eight Reading First elementary schools as it related to students' progress (n = 286 students) on early reading assessments of phonological awareness and letter naming–decoding fluency. Children's phonological awareness and letter naming–decoding fluency grew significantly from fall to spring. On average, across the three 60 min observations, teachers provided over 30 min a day of phonological awareness and phonics instruction and 15 min a day of vocabulary and comprehension instruction. Global ratings of instructional quality revealed two implementation factors: explicit and individualized implementation and meaningful interactions around text. Hierarchical linear modeling revealed that the amounts of specific instructional content, as well as how this instruction was implemented, was related to students' letter knowledge and phonological awareness skill growth.     

Comparing the Effects of Unknown-Known Ratios on Word Reading Learning Versus Learning Rates

An extension of G. L. Cates et al. (2003) investigation was conducted to determine if students’ cumulative learning rates would be superior for words read under a traditional drill and practice condition (as they were for spelling in the previous study) than under interspersal conditions of varying ratios of unknown to known words. Participants consisted of three intermediate grade students who were delayed readers. They received a less challenging ratio of unknown to known word (High-P sequencing) interspersal procedure, a more challenging ratio of unknown to known word interspersal training procedure, and a traditional drill and practice procedure in an alternating fashion across several tutoring sessions. Cumulative words read with mastery and cumulative rates of words read with mastery were measured across sessions for each participant under each instructional condition. Findings were consistent with the Cates et al., study revealing that children learn more words per minute of instructional time under the traditional drill and practice condition. These results further support examining instructional efficiency as well as effectiveness when making decisions about selecting and implementing interventions.     

The influence of word shading and word length on eye movements during reading

In three experiments rats were given short or long preexposure (4 or 10 sessions) to two compound flavours, AX and BX, according to an intermixed or a blocked schedule. Following preexposure, aversion conditioning trials were given with AX as the conditioned stimulus (CS). In Experiments 1 and 2, retardation and summation tests were then carried out to assess the inhibitory properties of B (an Espinet procedure). In Experiment 3, test trials evaluated generalization from AX to BX (the standard perceptual learning procedure). The results showed that B performed as an inhibitor of the unconditioned stimulus (US; an Espinet effect) only after long intermixed preexposure, whereas a reliable perceptual learning effect was observed both after short and after long preeexposure. The observation that B had no detectable inhibitory properties after short preexposure casts doubt on the suggestion that inhibitory learning is responsible for perceptual learning after brief exposure to AX and BX.     

Examining classroom influences on student perceptions of school climate: The role of classroom management and exclusionary discipline strategies

There is growing emphasis on the use of positive behavior supports rather than exclusionary discipline strategies to promote a positive classroom environment. Yet, there has been limited research examining the association between these two different approaches to classroom management and students' perceptions of school climate. Data from 1902 students within 93 classrooms that were nested within 37 elementary schools were examined using multilevel structural equation modeling procedures to investigate the association between two different classroom management strategies (i.e., exclusionary discipline strategies and the use of positive behavior supports) and student ratings of school climate (i.e., fairness, order and discipline, student–teacher relationship, and academic motivation). The analyses indicated that greater use of exclusionary discipline strategies was associated with lower order and discipline scores, whereas greater use of classroom-based positive behavior supports was associated with higher scores on order and discipline, fairness, and student–teacher relationship. These findings suggest that pre-service training and professional development activities should promote teachers' use of positive behavior support strategies and encourage reduced reliance on exclusionary discipline strategies in order to enhance the school climate and conditions for learning.     

Hierarchical organization of a reference system in newborn spontaneous movements

In this paper, we studied spontaneous newborn movements regarding the coordination of the four limbs, arms and legs, from a dynamic perspective. We used the method of recurrence plots to analyse the kinematic data from audiovisual recordings of neonates. We identified temporal and spatial synchronization of the four limbs that resulted in high recurrence patterns of biomechanical reference configurations. Furthermore, we identified transitions between linear and nonlinear epochs in the movement behavior of newborns on different time scales by means of recurrence quantification analysis. Results are discussed in the context of the concept of a structural hierarchy, in which different time scales correspond to hierarchical levels of organization.     

Relations between enabling skills and reading comprehension: a follow-up study of Latvian students from first to second grade

In order to examine the relationships among various phonological skills and reading comprehension, Latvian children were followed from grade 1 to grade 2 and were tested with a battery of phonological, word reading, and reading comprehension tasks. A principal component analysis of the phonological tasks revealed three salient factors: a phonemic awareness factor, a rapid naming factor, and a short-term memory factor. In order to analyze the relationship between various phonological skills and reading comprehension, a structural modeling analysis was performed. Phonemic awareness and rapid naming explained approximately the same amount of unique variance in reading comprehension, but phonemic awareness had most predictive power indirectly via word decoding. Only rapid naming had a significant direct impact on reading comprehension.     

Influence of consonantal context on the reading of vowels: evidence from children

When college students pronounce nonwords, their vowel pronunciations may be affected not only by the consonant that follows the vowel, the coda, but also by the preceding consonant, the onset. We presented the nonwords used by Treiman and colleagues in their 2003 study to a total of 94 first graders, third graders, fifth graders, and high school students to determine when these context influences emerge. According to some theories of reading development, early decoding is characterized by context-free links from graphemes to phonemes. However, we found that even children reading at the first-grade level (6-year-olds) were influenced to some extent by a vowel's context. The effect of context on vowel pronunciation increased in strength up to around the fifth-grade reading level (8- and 9-year-olds), and sensitivity to coda-to-vowel associations emerged no earlier than did sensitivity to onset-to-vowel associations. A connectionist model of reading reproduced this general pattern of increasing context effects as a function of training.     

词频与阅读方式对词跨行呈现效应的影响

通过使用眼动追踪技术,采用2（呈现条件：同行呈现、跨行呈现）×2（词频：高频、低频）×2（阅读方式：朗读、默读）的被试内实验设计,探讨了词频和阅读方式对词跨行呈现效应的影响。结果发现,呈现条件、词频和阅读方式的主效应显著,跨行呈现、低频和朗读的凝视时间和总注视时间更长、总注视次数更多;呈现条件之间在凝视时间上的差异,高频词大于低频词;呈现条件之间在凝视时间和总注视次数上的差异,朗读大于默读。结果表明,词跨行呈现干扰了阅读,且这种干扰作用受词频和阅读方式的影响。     

Genetic and environmental influences on individual differences in printed word recognition

The genetic and environmental etiologies of individual differences in printed word recognition and related skills were explored in 440 identical and fraternal twin pairs between 8 and 18 years of age. A theoretically driven measurement model identified five latent variables: IQ, phoneme awareness, word recognition, phonological decoding, and orthographic coding. Cholesky decomposition models on these five latent constructs revealed the existence of both common and independent genetic effects, as well as non-shared environmental influences. There was evidence for moderate genetic influences common between IQ, phoneme awareness, and word-reading skills, and for stronger IQ-independent genetic influences that were common between phoneme awareness and word-reading skills, particularly phonological decoding. Phonological and orthographic coding skills in word recognition had both significant common and significant independent genetic influences, with implications for "dual-route" and "connectionist" reading models, subtypes of reading disabilities, and the remediation of reading disabilities.     

Estimating the effect of word predictability on eye movements in Chinese reading using latent semantic analysis and transitional probability

Latent semantic analysis (LSA) and transitional probability (TP), two computational methods used to reflect lexical semantic representation from large text corpora, were employed to examine the effects of word predictability on Chinese reading. Participants' eye movements were monitored, and the influence of word complexity (number of strokes), word frequency, and word predictability on different eye movement measures (first-fixation duration, gaze duration, and total time) were examined. We found influences of TP on first-fixation duration and gaze duration and of LSA on total time. The results suggest that TP reflects an early stage of lexical processing while LSA reflects a later stage.
