According to the Lexical Restructuring Model (Metsala & Walley, 1998), 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) 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. 相似文献

Relevant aspects of the example provided by Raykov and Marcoulides (2001) are emphasized, specifically the distinctiveness of infinitely many members of its sequence of equivalent structural equation models. This emphasis appears to be needed in light of recent statements by Markus (2002), whose intended counterexamples do not present a disconfirmation of any of the developments of Raykov and Marcoulides (2001). Issues pertaining to differentiation between equivalent models are also discussed. 相似文献

Almost half of students who enter college require some sort of remedial coursework. Further, states are increasingly moving the responsibility of postsecondary remediation away from four-year campuses to two-year institutions. Scholars and policymakers have grappled with best practice for successfully filling in academic gaps and moving students forward, and there is variation both within and between states as to the ways in which remediation is defined, determined, and administered (Perin, 2006). Using a regression discontinuity design, this study seeks to answer the following question on one community college campus: How does placement into remedial services affect student outcomes, in particular, successful completion of an introductory college-level English course? Although this study focuses on a single community college system, the findings have bearing on a wider sector as the developmental placement practices of Harper Community College District are not unlike those implemented by two- and four-year campuses across the country. 相似文献

The design research methodology as it has currently developed centers on the creation of existence proofs, an important first step. What is needed then are the next steps of expanding the methodology to address the design problems of practical implementation prior to the steps involved in scaling up these designs. This article contributes to such an expansion through developing a systematic approach to learning from teachers' enactments of educational models. Design research focused on practical implementations by teachers can create knowledge regarding critical change processes, thus helping to create a theory of trajectories of change, or “implementation paths” (Bielaczyc & Collins, 2006a Collins, Joseph, & Bielaczyc, 2004). Here I propose using the Social Infrastructure Framework (Bielaczyc, 2006) to analyze the design of classroom social structures by developers and teachers in order to better understand their implications for constructing implementation paths. The analytic technique is exemplified through a case study involving a particular team of teachers who worked over the course of several years to adopt a knowledge-building communities approach (Bereiter, 2002; Scardamalia, 2002; Scardamalia & Bereiter, 1991 1994). The results are used to discuss implications for the methodology of design research. 相似文献

The purpose of this study was to examine persistence in school among students with Foetal Alcohol Spectrum Disorder (FASD) from the perspectives of the students themselves and their parents. Tinto’s (1975, 1997) Student Integration Model (SIM) provided the theoretical framework for this research. This model involves an interplay between (1) background characteristics and attributes affecting the level of goal commitment, (2) level of academic integration, and (3) level of social integration into the institution that determine whether or not a student will graduate. The findings showed limited support for Tinto’s SIM and that parental advocacy is strongly linked with persistence among adolescents with FASD. A new model showing the parents’ role in encouraging persistence through their actions at home and advocacy at the schools is presented. 相似文献

Social-psychological research conducted over the past 15 years provides compelling evidence that pervasive psychological threats are present in common academic environments—especially threats that originate in negative intellectual stereotypes—and that these threats undermine the real-world academic performance of non-Asian ethnic minority students and of women in math and science. As a consequence, common measures of academic performance, including both grades and test scores, systematically underestimate the intellectual ability of ethnic minority students and of women in quantitative fields (Walton & Spencer, 2009). We review evidence for these psychological threats, discuss their implications for the meaning and interpretation of common performance measures used in important admissions decisions, and address their implications for the efforts of colleges and universities to create positive academic environments that allow all students to thrive. 相似文献

We highlight critical conceptual and statistical issues and how to resolve them in conducting Satorra–Bentler (SB) scaled difference chi-square tests. Concerning the original (Satorra & Bentler, 2001) and new (Satorra & Bentler, 2010) scaled difference tests, a fundamental difference exists in how to compute properly a model's scaling correction factor (c), depending on the particular structural equation modeling software used. Because of how LISREL 8 defines the SB scaled chi-square, LISREL users should compute c for each model by dividing the model's normal theory weighted least-squares (NTWLS) chi-square by its SB chi-square, to recover c accurately with both tests. EQS and Mplus users, in contrast, should divide the model's maximum likelihood (ML) chi-square by its SB chi-square to recover c. Because ML estimation does not minimize the NTWLS chi-square, however, it can produce a negative difference in nested NTWLS chi-square values. Thus, we recommend the standard practice of testing the scaled difference in ML chi-square values for models M 1 and M 0 (after properly recovering c for each model), to avoid an inadmissible test numerator. We illustrate the difference in computations across software programs for the original and new scaled tests and provide LISREL, EQS, and Mplus syntax in both single- and multiple-group form for specifying the model M 10 that is involved in the new test. 相似文献

Compared to parametric models, nonparametric and semiparametric approaches to modeling nonlinearity between latent variables have the advantage of recovering global relationships of unknown functional form. Bauer (2005) proposed an indirect application of finite mixtures of structural equation models where latent components are estimated in the service of more flexibly recovering characteristics of the latent aggregate regression function. This article develops and evaluates delta method and parametric bootstrap approaches for obtaining approximate confidence intervals for Bauer's semiparametric approach to modeling latent nonlinear functions. Coverage rates of these approximate point-wise confidence intervals or nonsimultaneous confidence bands are evaluated by Monte Carlo and recommendations for their use are suggested. 相似文献

The continually rising percentage of the elderly population and the demand for geriatric nursing care are dramatically related. While it is true that most undergraduate programs prepare nurses for the care of geriatric patients, most receive limited academic preparation in the nursing curriculum (Williams & Mezey, 2000). This is particularly true in the Philippines where there is no stand-alone geriatric nursing course. This phenomenological study purports to capture the lived experiences of Filipino nursing students' dilemmas in geriatric care. Five Filipino senior nursing students and three clinical faculty from a comprehensive university in the Philippines were purposely chosen for the study. A two-part instrumentation was used. The first is the robotfoto, a Dutch term which means a cartographic sketch of the subject (Kelchtermans & Ballet, 2002). The second was a semi-structured face-to-face interview that was recorded with the consent of the participants. The full texts were phenomenologically reduced using a repertory grid to observe both cool and warm analyses, which facilitates the identification of unique conceptual clusters. Findings of this study have described the elements that define student dilemmas in geriatric care. The emerged Students' Dilemmas in Geriatrics Causality Quadrant (SDGCQ), which consists of (a) Foundational Deficit, (b) Psychological Deficit, (c) Relational-Attitudinal Deficit, and (d) Occupational Deficit, are valuable discussion points for needed reforms in the present-day nursing curriculum. 相似文献

It is difficult for busy health care providers to perform routine screening for older women's posttraumatic stress symptomatology. This difficulty is due, at least partially, to a paucity of instruments specifically tested on such a population. To address this issue, in this preliminary study we tested an abbreviated screen from the set of 20 items comprising the Distressing Event Questionnaire (DEQ; Kubany, Leisen, Kaplan, & Kelly, 2000a) on a convenience sample of 94 ethnically diverse older women (age 52–105). This new five-item derivation, named Brief Posttraumatic Stress Screening Scale (BPSSS), assesses posttraumatic stress based on the Diagnostic and Statistical Manual of Mental Disorders (DSM–IV; American Psychiatric Association, 1994). Its conciseness reduces the likelihood that older women would become fatigued during assessment, making it ideal for use in busy health care settings. In view of the hypothesized cohesiveness of the tool's five items, we expected the screen to be reliable. Because the BPSSS has only five items, a single factor was hypothesized to account for a large proportion of the variance in its items. We also expected that scores on the screen would correlate (to a certain extent) with those on measures of depression and perceived stress of a nontraumatic and nonmedical nature. A standardized alpha of .86 demonstrated high internal consistency of the BPSSS, and the exploratory factor analysis showed that one factor accounted for 58% of the five items' variance. Moreover, the correlations of BPSSS scores with scores on nontraumatic stress and depression were moderate yet significant (r = .37, p < .01 and r = .50, p < .01, respectively). 相似文献

Reynolds and Wheldall reviewed research relating to Reading Recovery (RR) and concluded that “RR has provided an excellent model in demonstrating how to plan, promote, and implement an intervention across an educational system and how to design a professional development programme” (2007, p. 218). They balanced this praise with concerns about the research base for RR, its effectiveness for the lowest‐performing first‐grade students, long‐term change in literacy achievement for RR students and RR’s cost‐effectiveness. This response aims to address these concerns by discussing four central issues of evidence‐based practice from their review: evidence of effectiveness; sustained gains; programme evaluation data from a response to intervention perspective; and cost‐effectiveness versus cost‐benefit. 相似文献

This article offers a critical analysis of discourses and power structures and the ways they operate in two instructors’ adult education and ESOL classrooms. The instructors defined learner experience in specific ways and subsequently used those definitions and drew on their learners’ experiences to define their curricula and pedagogy. They conceptualized learner experiences in ways that potentially empowered or emancipated learners from existing power structures. The data presented are part of a two‐year study of different lifelong learning and adult education contexts in the north‐eastern and mid‐western USA. Data sources included survey, interview, artifact collection, and observation methods. Data analysis was guided by a sociocultural theory of literacy development (The New London Group 1996, Gee 1996, 2003, Barton and Hamilton 1998), Holland et al.'s (1998) theories of figured worlds and identity development, Bakhtin’s (1963, 1975, 1979, 1986) theory of dialogism, and Foucault’s (1963, 1980) conceptualization of power. One instructor offered her learners a chance to empower themselves, that is, to find gratification by learning to appropriate mainstream ways of acting, thinking, believing, and using text. The discourse that promotes such instructional efforts is predominant in lifelong learning and adult education. In this discourse, referred to at the outset as one of coherence, learner experience, as a resource for language and literacy development, is essentialized as dispositional, meaning that correct or proper attitudes and beliefs are necessary for empowerment. The other instructor practised a reverse discourse, or what Gee (1996) referred to as a liberatory literacy. She positioned learners to critique the Discourses they encountered, including those they participated in, as movement toward emancipation, toward communicative competence or a critical stance in the world. In effect, learners reversed the panoptic framework and turned the gaze back upon existing power structures. In this case, learner experience was valued for the experiential positioning it offered learners. 相似文献

A study was conducted to estimate the reliability of oral examinations at the College of Medicine, The University of Iowa. In this paper, a part of the study is presented to provide the reader with an example of the applicability of a Balanced Incomplete Block Design (BIBD). This type of design is used when only fewer than all participating examiners can rate each examinee. Such a design was proposed originally by Yates in 1936.(1) The methods for analysing data obtained by BIBD were presented by Fleiss.(2) The reliability coefficient of the oral examination was .71, higher than some experts would anticipate in a similar situation. When some of the sources of error were eliminated by evaluating students' performances on audio‐tape, the reliability coefficient increased to .88. 相似文献

This qualitative study highlighted student perspectives on barriers to success at a community college located in a south Texas city. The study examined barriers to student success, the knowledge that successful students possess to overcome the barriers, and the actions that successful students undertake to overcome the barriers. Padilla's (2004) theoretical framework and methods for modeling student success provided the conceptual framework for the study. The data analysis resulted in the development of a local student success model and an implementation model for student services at the subject campus. 相似文献

The Peter Effect (Applegate & Applegate, 2004) claimed that one cannot be expected to give what one does not possess. We applied this notion to reading teacher preparation and hypothesized that teacher educators who do not possess an understanding of basic language constructs would not prepare teacher candidates with an understanding of these constructs considered essential for early reading success. Results from a survey of basic language constructs revealed similar patterns in performance between teacher educators and their respective teacher candidates, which served as initial validation of the Peter Effect in reading teacher preparation. 相似文献

This commentary on Zins and Illback's (1995) article, Consultation to Facilitate Planned Organizational Change in Schools, argues that the authors provided a solid foundation for well-planned, proactive, sustainable, internally-driven systemic change in schools that has yet to be widely realized. Their school organizational change model and more recent change models provide guidance for realizing a change from an individual, remedial focus to a population-based and preventative practice. 相似文献

School policy on teaching and the school learning environment (SLE) are the main school factors of the dynamic model of educational effectiveness (Creemers & Kyriakides, 2008). A longitudinal study in which 50 primary schools, 108 classes, and 2369 students participated generated evidence supporting the validity of the dynamic model. This article reports the results of a re-analysis of the data of this study in order to search for direct and indirect effects of school factors included in the model. Using multilevel structural equation modelling techniques, indirect effects of school policy on teaching and SLE upon achievement in mathematics and Greek language are demonstrated. Implications of findings are drawn. Comparing the results of the multilevel direct and indirect effect model with those from using a multilevel regression model, we demonstrate the importance of choosing appropriate conceptual models and using relevant methodological approaches to understand the dynamic nature of educational effectiveness. 相似文献

The current article represents a methodological proposal. It seeks to address the question of how one might recognize a discovery as a discovery without knowing in advance what is available to be discovered. We propose a solution and demonstrate it using data from a study previously reported by J. Roschelle (1992). Roschelle investigated 2 students' developing understandings of certain abstract features of Newtonian mechanics while working within a computer-based microworld, the Envisioning Machine. We employ an approach we term discovery as occasioned production to reexamine his data. Such an approach proceeds stepwise from the identification of some matter discovered, working backward to see just where that matter entered the conversation and then, finally, tracing from that point forward to illuminate how the proposal for a possible discovery was ultimately transformed into a discovery achieved. The notion of “evident vagueness,” borrowed from H. Garfinkel, M. Lynch, and D. Livingston's (1981) account of the discovery of an optical pulsar, emerges as an important feature of our analysis. Following H. Garfinkel (2002), we present our findings as a “tutorial problem” and offer a suggestion for how a program of practice studies in the learning sciences might be pursued. 相似文献

This study examines the values and practice in relation to assessment of a sample of 220 trainee teachers studying for a Postgraduate Certificate in Education, an initial teacher training and education (ITET) course, at the University of Cambridge, UK. The survey instrument was drawn from James and Pedder (2006), and was composed of questionnaire items that sought to elicit how trainees valued different classroom assessment practices, and the extent to which their own teaching complied with such values. The study draws additionally on the findings of James and Pedder (2006) to compare and contrast results with those for qualified teachers. Item and factor analyses revealed three dimensions that underpin trainees' classroom practice and values (promoting learning autonomy, performance orientation, making learning explicit). Values-practice gaps were greatest on promoting learning autonomy and performance orientation. Trainees valued practices associated with the former more than they implemented them in their teaching, while they implemented practices associated with the latter more than predicted by their values. Values-practice gaps suggested that trainees were constrained from implementing their values to a greater extent than qualified teachers, particularly with respect to these two factors. 相似文献
