This study used statistical simulation to calculate differential statistical power in dynamic structural equation models with groups (as in McArdle & Prindle, 2008). Patterns of between-group differences were simulated to provide insight into how model parameters influence power approximations. Chi-square and root mean square error of approximation (RMSEA) power approximation procedures were used to compare the effects of parameter manipulations and how researchers should interpret findings. The chi-square power of perfect fit calls for at least 270 individuals to detect moderate differences, whereas the RMSEA procedure of close fit seems to require as many as 1,450 participants. It is shown that parameters that provide input into the change score that the transfer leads to affect power versus indirect pathways. A discussion of differences in approximation values and future research directions follows. 相似文献

The purpose of this investigation is to compare a new (double-mean-centering) strategy to estimating latent interactions in structural equation models with the (single) mean-centering strategy (Marsh, Wen, & Hau, 2004, 2006) and the orthogonalizing strategy (Little, Bovaird, & Widaman, 2006; Marsh et al., 2007). A key benefit of the orthogonalizing strategy is that it eliminated the need to estimate a mean structure as required by the mean-centering strategy, but required a potentially cumbersome 2-step estimation procedure. In contrast, the double-mean-centering strategy eliminates both the need for the mean structure and the cumbersome 2-stage estimation procedure. Furthermore, although the orthogonalizing and double-mean-centering strategies are equivalent when all indicators are normally distributed, the double-mean-centering strategy is superior when this normality assumption is violated. In summary, we recommend that applied researchers wanting to estimate latent interaction effects use the double-mean-centering strategy instead of either the single-mean-centering or orthogonalizing strategies, thus allowing them to ignore the cumbersome mean structure. 相似文献

Administrative job satisfaction in higher education is influenced by intrinsic and interpersonal factors (Volkwein & Zhou, 2002, 2003). Pioneers of the “affect as information” hypothesis of emotion postulate that emotions provide value-laden information regarding whether goals, standards, and attitudes are impacted positively or negatively by events, agents, or objects (Clore, 1992, 1994; Clore & Ortony, 1988; Ortony, Clore, & Collins, 1988; Schwarz & Clore, 1988). This study explored the relationship between emotion and job satisfaction among community college administrators. Elevated satisfaction scores were associated with positive emotional temperaments and elevated emotional intelligence. Optimistic administrators in good moods were more satisfied than pessimistic administrators in bad moods. 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

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

In this article, I specify a conceptual framework for test validity research on content assessments taken by English language learners (ELLs) in U.S. schools in grades K–12. This framework is modeled after one previously delineated by Willingham et al. (1988), which was developed to guide research on students with disabilities. In this framework for research on ELLs, there are eight indicators of test comparability. Five of these indicators are measures of score comparability, while three indicators are measures of task comparability. To date, research has been conducted on six of the indicators of test comparability for content assessments taken by ELLs. For these indicators, findings from representative studies are summarized. For the remaining two indicators of test comparability for which no published research currently exists, I describe the types of research studies that are necessary to gather evidence to evaluate the comparability of content assessments for ELLs. 相似文献

Systematic-phonics instruction appears to be more effective than nonsystematic phonics instruction for teaching reading (Ehri, Nunes, Stahl, & Willows, 2001). In the present study, a systematic phonics approach was directly compared with a nonsystematic phonics approach for kindergarten children. Both approaches were delivered using computer programs teaching the same Dutch grapheme–phoneme correspondences. Both phonics-trained groups progressed to the same extent on productive letter-sound knowledge compared to the control group. However, on measures of phonemic awareness, spelling, and reading, the systematic phonics group made more progress than the nonsystematic phonics group and the control group. 相似文献

Oshima, Raju, Flowers, and Slinde (1998) described procedures for identifying sources of differential functioning for dichotomous data using differential bundle functioning (DBF) derived from the differential functioning of items and test (DFIT) framework (Raju, van der Linden, & Fleer, 1995). The purpose of this study was to extend the procedures for dichotomous DBF to the polytomous case and to illustrate how DBF analysis can be conducted with polytomous scoring, common to psychological and educational rating scales. The data set used was parent and teacher ratings of child problem behaviors. Three group contrasts (teacher vs. parent, boy vs. girl, and random groups) and two bundle organizing principles (subscale designation and random selection) were used for the DBF analysis. Interpretations of bundle indexes in the context of child problem behaviors were presented. 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

The significant increase in the numbers of students with autism combined with the need for better trained teachers (National Research Council, 2001) call for research on the effectiveness of alternative methods, such as consultation, that have the potential to improve service delivery. Data from 2 randomized controlled single-blind trials indicate that an autism-specific consultation planning framework known as the collaborative model for promoting competence and success (COMPASS) is effective in increasing child Individual Education Programs (IEP) outcomes (Ruble, Dalrymple, & McGrew, 2010; Ruble, McGrew, & Toland, 2011). In this study, we describe the verbal interactions, defined as speech acts and speech act exchanges that take place during COMPASS consultation, and examine the associations between speech exchanges and child outcomes. We applied the Psychosocial Processes Coding Scheme (Leaper, 1991) to code speech acts. Speech act exchanges were overwhelmingly affiliative, failed to show statistically significant relationships with child IEP outcomes and teacher adherence, but did correlate positively with IEP quality. 相似文献

AbstractMuch debate centers on the most necessary elements of teacher preparation programs, with many focusing on practice of core instructional tasks (Forzani 2014; Kennedy 2016), which may be diluted in alternative preparation programs (Forzani 2014). Teachers prepared in alternative programs tend to have greater difficulties with classroom management, instructional planning, and differentiated instruction (Darling-Hammond 2009; Wilson 2011); however, few studies have examined alternatively prepared STEM teachers’ beliefs and expectations about teaching and learning (Tigchelaar et al. 2010; Good et al. 2006), and fewer still have examined their beliefs about non-instructional responsibilities associated with the profession (LeTendre et al. 2001; Ovando 2001; Scriven 1994). This inquiry examines the expectations of a cohort of STEM practitioners transitioning into STEM teaching positions from an abbreviated alternative certification program; during their first year of teaching and concurrent final internship, the paid interns exhibited heightened emotional responses (i.e. crying, not eating, not sleeping) documented by university supervisors. Researchers utilized Self-Discrepancy Theory (Higgins 1987) to provide an understanding of how expectations can produce negative affect, such as anxiety or depression. Findings suggest this cohort of paid interns had expectations about both personal and non-instructional time, planning, school resources, and legal responsibilities incongruent with the realities of the job. Researchers call for further research on STEM practitioners’ beliefs and expectations of non-instructional tasks as they transition from accelerated M.A.T. programs into teaching. 相似文献

General practitioners (GPs) need advanced skills in geriatric assessment to be competent to treat the increasing number of elderly patients. Continuing medical education in geriatrics for GPs is heterogeneous, and not assessed for effectiveness. In this study we compared the educational effects of three geriatric post-graduate training methods on GPs. GPs in the health district of the Nijmegen University Medical Centre (The Netherlands) were offered a variety of training options in geriatric assessment: (1) a formal one-day teacher centered conference (TCC), (2) an interactive GP-centered day of workshops (GCW), and (3) participation in a project of knowledge translation, linked to a research project of geriatric intermediate care (GKT). Pre-post measures were taken of the attitudes of GPs towards the elderly (Aging Semantic Differential, 1969), attitudes towards geriatric patients (Maxwell & Sullivan, 1980; Rosencranz & McNevin, 1969) and geriatric competencies (Robinson, Barry, Renick, et al., 2001). After training, neither the attitudes towards the elderly nor geriatric patients changed in any of the three groups. The TCC did not show a significant change in perceived competencies, while the GCW and GKT group improved. A formal large group conference is ineffective in improving GPs' geriatric assessment skills, while small interactive workshops and participation in a project of knowledge translation are equally effective. None of the three training methods improved or worsened attitudes toward the elderly in general or the geriatric patients in particular. 相似文献

In structural equation modeling, Monte Carlo simulations have been used increasingly over the last two decades, as an inventory from the journal Structural Equation Modeling illustrates. Reaching out to a broad audience, this article provides guidelines for reporting Monte Carlo studies in that field. The framework of discourse is set by a number of steps to be taken in such research, matching outlines of experimental design by Paxton, Curran, Bollen, Kirby, and Chen (2001) and Skrondal (2000). Throughout the article, reference is made to exemplary publications and, occasionally, to imperfect reporting. 相似文献

Service-learning provides community service as well as authentic, curriculum-driven learning experiences (Furco &; Root, 2010) and has been an effective component of teacher education courses (García, Arias, Murri, &; Surna, 2010; Mitton-Kukner, Nelson, &; Descrochers, 2010; Spencer, Cox-Petersen, &; Crawford, 2005). With these authentic experiences, teachers construct conceptions of literacy learning as broader than classroom teaching and learning. This study investigates how 54 preservice elementary teachers (hereafter called teachers) learned about literacy development and cultural responsivity by engaging in a service-learning experience. 相似文献

Robust corrections to standard errors and test statistics have wide applications in structural equation modeling (SEM). The original SEM development, due to Satorra and Bentler (1988, 1994), was to account for the effect of nonnormality. Muthén (1993) proposed corrections to accompany certain categorical data estimators, such as cat-LS or cat-DWLS. Other applications of robust corrections exist. Despite the diversity of applications, all robust corrections are constructed using the same underlying rationale: They correct for inefficiency of the chosen estimator. The goal of this article is to make the formulas behind all types of robust corrections more intuitive. This is accomplished by building an analogy with similar equations in linear regression and then by reformulating the SEM model as a nonlinear regression model. 相似文献

This article responds to an article by A. Gupta, D. Hammer, and E. F. Redish (2010) that asserts that M. T. H. Chi's (1992, 2005) hypothesis of an “ontological commitment” in conceptual development is fundamentally flawed. In this article, I argue that Chi's theoretical perspective is still very much intact and that the critique offered by Gupta et al. is itself based on a flawed interpretation of Chi's theory. The purpose of this article is to address that misconception of Chi's work and to clarify her overall theoretical perspective. I begin by reviewing Chi's theory of ontological commitments, making an important comment about her position on the nature of expert conceptualizations. I review the methodological approaches used by J. D. Slotta and M. T. H. Chi (2006) to measure ontological commitments and comment on the instructional implications of Chi's theory. I then address the misconception held by Gupta et al. about Chi's work and call for more empirical research to tease apart the differences between Chi's view of “parallel ontologies” and Gupta et al.'s view of “flexible ontologies.” 相似文献

Through the use of in-depth interviews, this study investigated how gifted high-school students scoring high on at least one measure of perfectionism (self-oriented, socially prescribed, or other-oriented) perceived their perfectionism as developing. Findings suggested support for three family history models outlined by Flett, Hewitt, Oliver, and Macdonald (2002). Lack of challenge in their early academic experiences was also indicated as an influence. Findings are discussed within the context of the current literature on perfectionism in gifted students, and avenues for future research are suggested. 相似文献

In a national evaluation of environmental literacy in Israel, (Negev, Sagy, Garb, Salzberg, & Tal, 2008), the authors included both multiple choice questions and open questions. In this article the authors describe the qualitative analysis of the answers to an open question regarding a local environmental problem. Most participants specified solid waste, open spaces, or air pollution as the main issues. The perceived solutions were generally at the governmental level, including planning, infrastructure, legislation, and enforcement. The authors describe relations in these responses between the problems, their causes and solutions, and between the quality of these answers and the general environmental literacy of the participants. The authors end with a discussion of the special contributions and potential of open-ended questions for environmental education research. 相似文献

Our article focuses on using portfolio assessment to craft quality teaching. Extant research literature on portfolio assessment suggests that the primary purpose of assessment is to serve learning, and portfolio assessments facilitate the process of making linkages among assessment, curriculum, and student learning (Asp, 2000; Bergeron, Wermuth, & Hammar, 1997; Cohen & Wiener, 2003; Neill & Mitchell, 1995; O'Malley & Pierce, 1996; Smith & Ylvisaker, 1993; Yancey, 1996). Because a learning portfolio is a collection of student work samples over time, it provides teachers with opportunities to understand the process of student learning. This is especially important in the current educational context where teachers are expected to teach all students, including English language learners, to develop high-level thinking and content knowledge aligned with Common Core State Standards. To support teachers to provide quality teaching that meets Common Core State Standards for diverse English language learners, we begin our article with 3 important reasons for using portfolio assessment. We then describe procedures for implementing portfolio assessment in individual classrooms. 相似文献
