Best Practices for English Language Learners in Massachusetts: Five Years After The Question 2 Mandate

Educating English language learners (ELLs) presents a challenge for teachers and policy makers; the population of ELLs increases, yet their achievement trails that of their native English-speaking peers. In November 2002, Massachusetts voters supported a law that mandated Sheltered English Immersion (SEI) as the primary means of instruction for ELLs, effectively ending transitional bilingual education. This report examines key considerations in educating ELLs, and in implementing SEI in Massachusetts schools. It also presents case studies of three schools making significant strides with ELLs through innovative programming built around SEI methods yet maintaining important bilingual education practices that promote educational equity. Cross-case analysis identified themes about strategic data use, staff recruitment, and supports for students and families.     

The surprising viability of a simple alternate estimation procedure for construction of large‐scale structural equation measurement models

As part of developing a comprehensive strategy for structural equation model building and assessment, a large‐scale Monte Carlo study of 7,200 covariance matrices sampled from 36 population models was conducted. This study compared maximum likelihood with the much simpler centroid method for the confirmatory factor analysis of multiple‐indicator measurement models. Surprisingly, the contribution of maximum likelihood to model analysis is limited to formal evaluation of the model. No statistically discernible differences were obtained for the bias, standard errors, or mean squared error (MSE) of the estimated factor correlations, and empirically obtained maximum likelihood standard errors for the pattern coefficients were only slightly smaller than their centroid counterparts. Further supporting the recommendations of Anderson and Gerbing (1982), the considerably faster centroid method may have a useful role in the analysis of these models, particularly for the analysis of large models with 50 or more input variables. These results encourage the further development of a comprehensive research paradigm that exploits the relative strengths of both centroid and maximum likelihood as complementary estimation procedures along an integrated exploratory‐confirmatory continuum of model specification, revision, and formal evaluation.     

Models and Strategies for Factor Mixture Analysis: An Example Concerning the Structure Underlying Psychological Disorders

The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models.     

The Growth of Phonological Awareness by Children With Reading Disabilities: A Result of Semantic Knowledge or Knowledge of Grapheme-Phoneme Correspondences?

According to the Lexical Restructuring Model (Metsala & Walley, 1998 Metsala, J. L. and Walley, A. C. 1998. “Spoken vocabulary growth and the segmental restructuring of lexical representation: Precursors to phonemic awareness and early reading ability”. In Word recognition in beginning literacy, Edited by: Metsala, J. L. and Ehri, L. C. 89–120. Mahwah, NJ: Lawrence Erlbaum Associates, Inc.  [Google Scholar]), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) Ziegler, J. C. and Goswami, U. 2005. Reading acquisition, developmental dyslexia, and skilled reading across languages: A psycholinguistic grain size theory.. Psychological Bulletin, 131: 3–29. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness.     

Creating Inclusive,Literacy-Embedded Play Centers in a Children's Museum: Connecting Theory to Practice

Preservice teachers enrolled in an early literacy or developmental preschool course collaborated in order to create inclusive, literacy-embedded play centers at a local children's museum. Using a grounded theory approach, theoretical questions were generated after analyzing multiple data sources. The focus of this paper is how preservice teachers connected theory to practice in an authentic setting. The importance of connecting theory to practice, the place of play in assessment, and the viability of children's museums as alternative field placements are discussed. Implications for preservice teacher education are presented.     

The Choice of Response Probability in Bookmark Standard Setting: An Experimental Study

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the resulting judgments. This article presents the results of an experiment in which content experts were randomly assigned to one of two response probability conditions: .67 and .80. If the standard-setting judgments collected with the bookmark procedure are internally consistent, both conditions should produce highly similar cut scores. The results showed substantially different cut scores for the two conditions; this calls into question whether content experts can produce the type of internally consistent judgments that are required using the bookmark procedure.     

Improving the reading skills of young people with Duchenne muscular dystrophy in preparation for adulthood

Duchenne muscular dystrophy (DMD) is a progressive genetic condition that affects both muscle and brain. Children with DMD are at risk of psycho‐social difficulties such as poor academic achievement and behavioural and socio‐emotional problems. This article by Janet Hoskin and Angela Fawcett, both from the University of Swansea, describes how 34 participants with DMD took part in a 36‐week online literacy intervention which was delivered in partnership between home and school. The key objective was to improve reading skill. Participants were re‐tested at 36 weeks for single word and text level reading, comprehension, fluency, processing and timed single word reading. Pre and post results indicated that children who followed the intervention for 36 weeks made significant improvement in their single word reading (p = <0.0001), timed single word reading (p = <0.0001) and text level reading (p = <0.004). They also made significant improvement in their fluency and comprehension scores. The results showed that children with DMD and related literacy difficulties benefit from a regular, structured and systematic synthetic phonics programme. With young people with DMD increasingly living into adulthood, early literacy intervention is particularly important to ensure optimum career and training opportunities.
