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

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

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

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

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

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

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

This article reviews Check-In, Check-Out (CICO; Hawken & Horner, 2003) as an intervention within a multitiered system of support. Although literature has emerged demonstrating successful intervention outcomes for a wide range of students (e.g., Campbell & Anderson, 2011; Hawken & Horner, 2003), insufficient attention has focused on the administrative and organizational systems needed for high-fidelity, sustained adoption of these practices to maximize student outcomes. We address this need by demonstrating how to explicitly and systematically embed CICO into the multitiered system of supports by reviewing data, systems, and practices needed to sustain high-quality Tier 2 interventions such as CICO. One school district's systems implementation data and student outcome data are shared highlighting lessons learned during training, initial implementation, and follow-up related to CICO systems in schools. The article emphasizes the roles of school psychologists as well as the importance of collaboration with other educators in CICO implementation. 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

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 study investigates the ongoing debate in the conceptual change literature between unitary and elemental perspectives on students' knowledge structure coherence. More specifically, the current study explores two potential explanations for the conflicting results reported by Ioannides and Vosniadou (2002)and diSessa, Gillespie, and Esterly (2004) in terms of differences in coding schemes and differences in student populations. The current study addresses these questions by applying the coding schemes from both studies to interviews with 201 students drawn from the United States, the Philippines, Turkey, China, and Mexico. The analyses focus first on the coding schemes, suggesting that differences in coding schemes seem unlikely to account for the differences in the original studies. The analyses then focus on potential differences between student populations, suggesting that some differences exist in terms of consistency and meanings that might result from language, culture, or educational systems, but that these differences are too small to account for the radical differences in the findings of the original studies. Two additional explanations are then proposed and explored involving the instruments and the epistemological stances invoked for the students. Overall, the results align more closely with the findings of diSessa, Gillespie, and Esterly (2004). [Supplemental materials are available for this article.

This article describes a computerized adaptive test (CAT) based on the uniform item exposure multi-form structure (uMFS). The uMFS is a specialization of the multi-form structure (MFS) idea described by Armstrong, Jones, Berliner, and Pashley (1998). In an MFS CAT, the examinee first responds to a small fixed block of items. The items comprising that block may be unrelated to each other, or they may comprise a testlet (Wainer and Kiely, 1987) After the first block of items has been administered, adaptation takes place in the choice of the next block to be administered and subsequent blocks. The uMFS design integrates item exposure control, as well as content balancing and other test development needs, into the design of the CAT, instead of placing those activities in the online implementation. We show that it is possible to implement item exposure control, in a very thorough way, in the psychometric specifications of the item blocks. 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

This rejoinder provides comment on issues raised by Schwartz, Hobsbaum, Briggs and Scull (2009) in their article about evidence‐based practice and Reading Recovery (RR), written in response to Reynolds and Wheldall (2007). Particular attention is paid to the processes and findings of the What Works Clearinghouse evaluation of RR. The suggestion that this evaluation is flawed casts doubt about some of its findings. The authors maintain their earlier stance that RR is effective for many students but do not accept that there is evidence that initial gains are sustained through the primary grades, that RR is an efficient tier two intervention in a response to intervention approach and that significant cost benefits have been demonstrated in education systems. It is concluded that research into alternative interventions that could be implemented at lower cost is warranted. 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

We surveyed business students in the U. S. (n = 256) and Chile (n = 310). The survey included measures drawn from studies of pro-environmental behavior using Schwartz's norm activation theory (Schwartz, 1977), the theory of reasoned action (Ajzen & Fishbein, 1980), and a values-beliefs-norms model created by Stern, Dietz, Abel, Guagnano, and Kalof (1999). Our results show Chilean business students are more altruistic than business students in the United States and Chilean students felt stronger pressures from their peers to engage in pro-environmental behaviors. Chilean business students also expressed higher levels of awareness of environmental problems, a greater sense of obligation to protect the environment, a stronger willingness to limit property rights, and stronger intentions to engage in pro-environmental behavior. 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

This study compared the affordances of 4 multimedia learning environments for specific learning processes. The environments covered the same domain but used different instructional approaches: (a) hypermedia learning, (b) observational learning, (c) self-explanation-based learning, and (d) inquiry learning. Although they all promote an active attitude, they differ in the specific learning processes they intend to foster. In earlier research (Eysink et al., 2009), we found that learners involved in self-explanation-based or inquiry learning had the highest learning outcomes. In these approaches learners were required to generate (parts of) the subject matter, from which we concluded that they presumably stimulated learners to elaborate. Therefore, in the present study we expected that learners involved in self-explanation-based or inquiry learning would engage in more learning processes connected to elaboration than would learners involved in hypermedia or observational learning. Forty participants worked through the learning environments while thinking aloud; their protocols were coded using a generic learning processes scheme. Results showed that self-explanation-based learning and inquiry learning led to greater engagement in learning processes in general and more elaborative processes in particular. The results suggest that elaboration is indeed the key process explaining differences in learning across different instructional approaches within multimedia learning environments. 相似文献
