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 Perin , D. ( 2006 ). Can community colleges protect both access and standards? The problem of remediation . Teachers College Record 108 ( 3 ), 339373 .[Crossref], [Web of Science ®] [Google Scholar]). 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

Nearly a decade ago, Smith, Street, and Olivarez (2002 Smith , A. B. , Street , M. A. , & Olivarez , A. ( 2002 ). Early, regular, and late registration and community college student success: A case study . Community College Journal of Research and Practice , 26 ( 3 ), 261273 .[Taylor & Francis Online] [Google Scholar]) discussed the impact of a late registration policy on students at a community college in Texas. Their study revealed that the policy was detrimental to student success and should be discontinued. There are still colleges, however, that continue the policy of late registration, and this study examines the impact on student success at one community college in Florida. The results reflect that students who register on or after the first day of class are not as successful academically when compared to students who registered early.  相似文献

This mixed-methods study develops, operationalizes, and tests a new conceptual model of community college student engagement. Themes emerging from participant observations and semistructured interviews with 30 adult students enrolled at a Large Best Practices Community College (LBPCC) over the 2005–2006 academic year are used to guide selection of Self-Determination Theory (Deci & Ryan, 1985 Deci , E. L. & Ryan , R. M. ( 1985 ). Intrinsic motivation and self-direction behavior . New York : Plenum .[Crossref] [Google Scholar], 2000 Deci , E. L. & Ryan , R. M. ( 2000 ). Intrinsic and extrinsic motivations: Classic definitions and new directions . Contemporary Educational Psychology , 25 , 5467 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar], 2002 Deci , E. L. & Ryan , R. M. ( 2002 ). Handbook of self-determination research . Rochester , NY : University of Rochester . [Google Scholar]) to frame the new conceptual model. Structural equation modeling techniques confirm that variables and relationships proposed by the new model represent a good fit with data from over 1,000 students surveyed in the Community College Survey of Student Engagement. Findings from this study suggest that community college engagement and related outcomes can be fostered by tuning campus policies, practices, and climates to promote students' senses of belonging, competence, and autonomy.  相似文献

There is limited research demonstrating direct instruction (DI) as an effective language intervention for students with autism spectrum disorders (ASD) and developmental disabilities (DD). Existing research has shown that instruction using partial implementation of DI programs resulted in student learning (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and instruction using whole lessons resulted in positive instructional effects for students with ASD and DD (Ganz, 2007 Ganz, M. L. (2007). The lifetime distribution of the incremental societal costs of autism. Archives of Pediatrics & Adolescent Medicine, 161, 343&349.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). However, it is not known whether DI is more effective than other language interventions. The purpose of this study was to compare DI to an established intervention, discrete trial teaching. Thirteen students with ASD or participated in the study and data were collected using curriculum-based assessment. An independent samples t-test indicated that there was a statistically significant difference in student performance for the group who received DI. Results and their implications will be discussed.  相似文献

The purpose of this study was to examine the psychometric properties of the Compassionate Love for Close Others and for Strangers and Humanity Scale (Sprecher & Fehr, 2005 Sprecher , S. , & Fehr , B. ( 2005 ). Compassionate love for close others and humanity . Journal of Social and Personal Relationships , 22 , 629651 .[Crossref], [Web of Science ®] [Google Scholar]) among older people. The psychometric properties of the two versions of the scale were analyzed by means of factor analysis, internal consistency, and criterion-related validity methods. The exploratory factor analysis supported a one-dimensional structure of the scale. The Compassionate Love for Close Others and for Strangers and Humanity Scale presented good psychometric properties, with satisfactory levels of internal consistency. The criterion-related validity of the scale was established by correlating compassionate love for others and for humanity with forgiveness, gratitude, and religiosity. Those who experience high levels of compassionate love for close others and strangers/humanity were more likely to report unconditional forgiveness, gratitude, and religiosity. The Portuguese version of the Compassionate Love for Close Others and for Strangers and Humanity Scale seems to be reliable and valid. The significance and limitations of the results are discussed.  相似文献

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. 89120. 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: 329. [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.  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, L. A., Dalrymple, N. J. and McGrew, J. H. 2010. The effects of consultation on Individualized Education Program outcomes for young children with autism: The collaborative model for promoting competence and success. Journal of Early Intervention, 32: 286301. doi:10.1177/1053815110382973[Crossref], [PubMed] [Google Scholar]; Ruble, McGrew, & Toland, 2011 Ruble, L., McGrew, J. and Toland, M. Randomized controlled study of teacher training in autism. Poster session presented at the meeting of the American Psychological Association. Washington, DC. August.  [Google Scholar]). 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 Leaper, C. 1991. Influence and involvement in children's discourse: Age, gender, and partner effects. Child Development, 62: 797811. doi:10.1111/j.1467-8624.1991.tb01570.x[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) 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

Abstract

Much debate centers on the most necessary elements of teacher preparation programs, with many focusing on practice of core instructional tasks (Forzani 2014 Forzani, F. M. 2014. Understanding “Core Practices” and “Practice-Based” teacher education learning from the past. Journal of Teacher Education 65 (4):35768. doi: 10.1177/0022487114533800.[Crossref], [Web of Science ®] [Google Scholar]; Kennedy 2016 Kennedy, M. 2016. Parsing the practice of teaching. Journal of Teacher Education 67 (1):617. doi: 10.1177/0022487115614617.[Crossref], [Web of Science ®] [Google Scholar]), which may be diluted in alternative preparation programs (Forzani 2014 Forzani, F. M. 2014. Understanding “Core Practices” and “Practice-Based” teacher education learning from the past. Journal of Teacher Education 65 (4):35768. doi: 10.1177/0022487114533800.[Crossref], [Web of Science ®] [Google Scholar]). Teachers prepared in alternative programs tend to have greater difficulties with classroom management, instructional planning, and differentiated instruction (Darling-Hammond 2009 Darling-Hammond, L. 2009. Educational opportunity and alternative certification: New evidence and new questions. Policy Brief (1). Stanford, CA: Stanford Center for Opportunity Policy in Education. [Google Scholar]; Wilson 2011 Wilson, S. 2011. Effective STEM teacher preparation, induction, and professional development. In National Research Council’s Workshop on Successful STEM Education in K–12 Schools. Washington, DC. http://sites.nationalacademies.org/dbasse/bose/dbasse_080128#.UgEMEFPkDDn. [Google Scholar]); however, few studies have examined alternatively prepared STEM teachers’ beliefs and expectations about teaching and learning (Tigchelaar et al. 2010 Tigchelaar, A., N. Brouwer, and J. Vermunt. 2010. Tailor-made: Towards a pedagogy for educating second-career teachers. Educational Research Review 5 (2):16483.[Crossref], [Web of Science ®] [Google Scholar]; Good et al. 2006 Good, T., M. McCaslin, H. Tsang, J. Zhang, C. Wiley, A. Rabidue Bozack, and W. Hester. 2006. How well do 1st-year teachers teach: Does type of preparation make a difference? Journal of Teacher Education 57 (4):41030.[Crossref], [Web of Science ®] [Google Scholar]), and fewer still have examined their beliefs about non-instructional responsibilities associated with the profession (LeTendre et al. 2001 LeTendre, G.K., D.P. Baker, M. Akiba, B. Goesling, and A. Wiseman. 2001. Teachers' work: Institutional isomorphism and cultural variation in the U.S., Germany, and Japan. Educational Researcher 30 (6):3–15. doi: 10.3102/0013189X030006003.[Crossref] [Google Scholar]; Ovando 2001 Ovando, M. N. 2001. Teachers' perceptions of a learner-centered teacher evaluation system. Journal of Personnel Evaluation in Education 15 (3):213–231. [Google Scholar]; Scriven 1994 Scriven, M. 1994. Duties of the teacher. Journal of Personnel Evaluation in Education 8 (2):15184. doi: 10.1007/BF00972261.[Crossref] [Google Scholar]). 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 Higgins, E. T. 1987. Self-discrepancy: A theory relating self and affect. Psychological Review 94 (3):31940.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) 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

This article reviews Check-In, Check-Out (CICO; Hawken & Horner, 2003 Hawken, L., & Horner, R. (2003). Evaluation of targeted intervention within a schoolwide system of behavior support. Journal of Behavioral Education, 12, 225240.[Crossref] [Google Scholar]) 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 Campbell, A., & Anderson, C. M. (2011). Check-In/Check-Out: A systematic evaluation and component analysis. Journal of Applied Behavior Analysis, 4, 315326.[Crossref], [Web of Science ®] [Google Scholar]; Hawken & Horner, 2003 Hawken, L., & Horner, R. (2003). Evaluation of targeted intervention within a schoolwide system of behavior support. Journal of Behavioral Education, 12, 225240.[Crossref] [Google Scholar]), 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

The purpose of this study was to examine relationships among memory aging knowledge and memory self-appraisal in college students and community-dwelling older adults. Participants completed the Knowledge of Memory Aging Questionnaire ([KMAQ] Cherry, Brigman, Hawley, & Reese, 2003 Cherry , K. E. , Brigman , S. , Hawley , K. S. , & Reese , C. M. ( 2003 ). The knowledge of memory aging questionnaire: Effects of adding a ‘don't know’ response option . Educational Gerontology , 29 , 427446 . doi: 10.1080/713844360 [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) and the Memory Functioning Questionnaire ([MFQ] Gilewski, Zelinski, & Schaie, 1990 Gilewski , M. J. , Zelinski , E. M. , & Schaie , K. ( 1990 ). The memory functioning questionnaire for assessment of memory complaints in adulthood and old age . Psychology and Aging , 5 , 482490 . doi: 10.1037/0882-7974.5.4.482 [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). We hypothesized that poorer performance on the KMAQ stereotype scale, suggesting an ageist response bias, would be associated with more negative self-appraisals of memory. Results confirmed that responses on the KMAQ stereotype scale were significantly associated with responses on the MFQ Frequency of Forgetting scale and two shorter scales derived from the full MFQ, the memory self-efficacy scale (Zelinski & Gilewski, 2004 Zelinski , E. M. , & Gilewski , M. J. ( 2004 ). A 10-item Rasch modeled memory self-efficacy scale . Aging & Mental Health , 8 , 293306 . doi: 10.1080/13607860410001709665 [Taylor & Francis Online], [Web of Science ®] [Google Scholar]), and a revised Seriousness of Forgetting scale after controlling for age and educational level. Implications of these findings for the development of instructional materials to improve memory aging knowledge and memory self-appraisal in adulthood are discussed.  相似文献

Paul Fain (2011 Fain , P. ( 2011 , September 26 ). Questioning assumptions. Inside Higher Ed. Retrieved from http://www.insidehighered.com/  [Google Scholar]), cited community college leaders who overwhelmingly voted at the Reimagining Community Colleges invitation-only conference held September 23, 2011 in New York City, for team teaching and other innovations as the most important fix for remedial education in community colleges. Team teaching is not common in postsecondary education and is difficult to do well. This paper presents the argument that it is the contextualized material that leads to team teaching success. Contextualized learning has not been rigorously researched, and it is far from having enough research for most community colleges to learn from and adapt. Although Perin (2011 Perin , D. ( 2011 ). Facilitating student learning through contextualization: A review of evidence . Community College Review , 39 ( 3 ), 268295 .[Crossref] [Google Scholar]) found that contextualized learning had been used in various ways in educational literature, this paper focuses on the integration of remedial education materials into a community college career technical skills coursework.  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 Maxwell, A. J. and Sullivan, N. 1980. Attitudes toward the geriatric patient among family practice residents. Journal of the American Geriatric Society, 2(8): 341345.  [Google Scholar]; Rosencranz & McNevin, 1969 Rosencranz, H. A. and McNevin, T. E. 1969. A factor analysis of attitudes towards the aged. Gerontologist, 9: 5559. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) and geriatric competencies (Robinson, Barry, Renick, et al., 2001 Robinson, B. E., Barry, P. P., Renick, N., Bergen, M. R. and Stratos, G. A. 2001. Physician confidence and interest in learning more about common geriatric topics: A needs assessment. Journal of the American Geriatric Society, 49: 963967. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). 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

Andrew Elby (this issue) argues that researchers in the field of personal epistemology should beware insistence on a narrow definition of epistemology to guide this work. His argument is a response to suggestions (Hofer & Pintrich, 1997 Hofer, B. K. and Pintrich, P. R. 1997. The development of epistemological theories: Beliefs about knowledge and knowing and their relation to learning.. Review of Educational Research, 67(1): 88140. [Crossref], [Web of Science ®] [Google Scholar]; Sandoval, 2005 Sandoval, W. A. 2005. Understanding students' practical epistemologies and their influence on learning through inquiry.. Science Education, 89: 634656. [Crossref], [Web of Science ®] [Google Scholar]) that the study of personal epistemology should focus on people's views about knowledge and knowing and not conflate those with views about learning. His main concern is that learners' views about knowledge and their views about learning may, in fact, be conflated and that an insistence on definitional clarity could lead to a mischaracterization of cognitive structures. In this response I argue that clarity in the definition of theoretical constructs does not imply exclusion of views about learning from the study of personal epistemology. Furthermore, given the history of this area of research, failing to more clearly define our constructs makes real theoretical progress difficult.  相似文献

Nearly a decade ago, Sullivan presented her interpretation of the four generations of community college leaders by describing them as “the founding fathers, the good managers, the collaborators, and the millennium generation” (Sullivan, 2001 Sullivan , L. G. ( 2001 ). Four generations of community college leadership . Community College Journal of Research and Practice , 25 , 559571 .[Taylor & Francis Online] [Google Scholar], p. 559). She predicted a shift to frames utilizing the Four-Frame Model of Leadership by Bolman and Deal (1991 Bolman , L. G. , & Deal , T. E. (1991). Leadership and management effectiveness: A multi-frame, multi-sector analysis. Human Resource Management , 30, 509534.[Crossref], [Web of Science ®] [Google Scholar]). This article provides a discussion of the research that has been published using the Bolman and Deal model and a synopsis of the current leadership challenges faced by community college leaders. And finally, a new prediction is made of the values, skills, and frames needed for these leaders.  相似文献

Research on learning to teach repeatedly cites the disjuncture in teaching practices promoted across universities and K–12 schools. Much of the literature that is focused on this “two-worlds pitfall” (Feiman-Nemser & Buchmann, 1985 Feiman-Nemser, S. and Buchmann, M. 1985. Pitfalls of experience in teacher preparation. Teachers College Record, 87(1): 5365. [Web of Science ®] [Google Scholar]) describes the influence of cooperating teachers' more traditional teaching practices on teacher candidates' developing practice. This article, however, provides a case study of a student teacher whose commitment to social constructivist practices was reinforced by the intersection of competing views of teaching and mentoring that collided during her student teaching. We highlight the significant impact of the cooperating teacher's approach to mentoring—more so than teaching—on a student teacher's developing practice. We conclude with recommendations for supporting student and cooperating teachers to develop shared understandings of the purpose of student teaching and mentoring and to engage in educative dialogues about teaching that support the cross-institutional negotiations inherent in mentoring and learning to teach.  相似文献

The press for implementing technology based instructional delivery systems in community and technical colleges is well documented. Yet faculty face numerous challenges in integrating technology into instruction (AL-Bataineh & Brooks, 2003 AL-Bataineh , A. & Brooks , L. ( 2003 ). Challenges, advantages, and disadvantages of instructional technology in the community college classroom . Community College Journal of Research and Practice , 27 , 473484 .[Taylor & Francis Online] [Google Scholar]; Groves & Zemel, 2000 Groves , M. & Zemel , P. ( 2000 ). Instructional technology adoption in higher education: An action research case study . International Journal of Instructional Media , 27 ( 1 ), 5766 . [Google Scholar]; Khoury, 1997 Khoury , R. M. ( 1997 ). The unkept promise . Community College Week , 10 ( 1 ), 46 . [Google Scholar]). Stimulating faculty ownership in technology, diffusion of technology use throughout institutions, and linking technology use to the faculty reward system are key concerns addressed in this proposed tool for evaluating faculty technology integration performance. The tool is based on research on faculty development (Howery, 1997 Howery , C. B. ( 1997 ). Recognizing and rewarding the professional and scholarly work of sociologists . Unpublished report to the Council of the American Sociological Association . [Google Scholar]) and the technology adoption process (Hall, Loucks, Rutherford, & Newlove, 1975 Hall , G. E. , Loucks , S. F. , Rutherford , W. L. , & Newlove , B. W. ( 1975 ). Levels of use of the innovation: A framework for analyzing innovation adoption . The Journal of Teacher Education , 26 ( 1 ), 5256 .[Crossref], [Web of Science ®] [Google Scholar]). Stimulating development of faculty expertise linked to technology goals is the goal of applying the tool.  相似文献

Tanzania, like many other African countries, has experienced a rapid expansion of its secondary education sector. This has resulted in large numbers of secondary school graduates struggling to build a future through continuing education or finding employment. 1 1. During the past decade, secondary education enrolment in Tanzania has increased rapidly, net enrolment in secondary education in 2009 being 31.3% (URT 2009 United Republic of Tanzania (URT). 2009. Basic education statistics in Tanzania. National data. Dar es Salaam: The Ministry of Education and Vocational Training. http://216.15.191.173/statistics.html.  [Google Scholar]). Still, transition rates from primary to secondary education are among the lowest in Sub-Saharan Africa. Although almost equal in lower years of primary education, the proportion and performance of girls decrease while moving to the upper secondary education. For a recent review on gender and education in Tanzania, see Okkolin, Lehtomäki, and Bhalalusesa (2010 Okkolin, M.-A., Lehtomäki, E. and Bhalalusesa, E. 2010. Successes and challenges in the education sector development in Tanzania: Focus on gender and inclusive education. Gender and Education, 22(1): 6371. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]). Students are faced with the difficult task of assessing their opportunities in the face of various challenges and making plans to build a better life. The presented research uses empathy-based stories to identify which elements were considered to be important by students in determining their success in education. The analysis of narrative data represents a shared cultural meaning on the social and cultural support available to students. The findings suggest that using empathy-based stories as a methodological tool can provide valuable insights for culture-sensitive and intercultural research through its ability to widen the context of discovery.  相似文献

Relevant aspects of the example provided by Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142149. [Taylor & Francis Online], [Web of Science ®] [Google Scholar] 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) Markus, K. A. 2002. Statistical equivalence, semantic equivalence, eliminative induction and the Raykov–Marcoulides proof of infinite equivalence. Structural Equation Modeling, 9: 503522. [Taylor & Francis Online], [Web of Science ®] [Google Scholar], whose intended counterexamples do not present a disconfirmation of any of the developments of Raykov and Marcoulides (2001) Raykov, T. and Marcoulides, G. A. 2001. Can there be infinitely many models equivalent to a given covariance structure model?. Structural Equation Modeling, 8: 142149. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]. Issues pertaining to differentiation between equivalent models are also discussed.  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 Marsh, H. W., Wen, Z. and Hau, K. T. 2004. Structural equation models of latent interactions: Evaluation of alternative estimation strategies and indicator construction.. Psychological Methods, 9: 275300. [Taylor & Francis Online], [Web of Science ®] [Google Scholar], 2006 Marsh, H. W., Wen, Z. and Hau, K. T. 2006. “Structural equation models of latent interaction and quadratic effects”. In A second course in structural equation modeling Edited by: Hancock, G. and Mueller, R. 225265. Greenwich, CT: Information Age.  [Google Scholar]) and the orthogonalizing strategy (Little, Bovaird, & Widaman, 2006 Little, T. D., Bovaird, J. A. and Widaman, K. F. 2006. On the merits of orthogonalizing powered and product term: Implications for modeling interactions among latent variables.. Structural Equation Modeling, 13: 497519. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]; Marsh et al., 2007 Marsh, H. W., Wen, Z., Hau, K. T., Little, T. D., Bovaird, J. A. and Widaman, K. F. 2007. Unconstrained structural equation models of latent interactions: Contrasting residual- and mean-centered approaches.. Structural Equation Modeling, 14: 570580. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]). 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

[Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Weingartner & Klin, 2005 Weingartner, K. M. and Klin, C. M. 2005. Perspective taking during reading: An on-line investigation of the illusory transparency of intention.. Memory & Cognition, 33: 4858. [Crossref] [Google Scholar]) have shown that readers are not always accurate at taking a story character's perspective. When readers evaluated a character's understanding of a written message, they mistakenly took into account information that was inaccessible to that character. The results from the three experiments reported here demonstrate that this “illusory transparency of intention” is not dependent on the message readers' communicative role: Even when the message was composed for one character but read by another, readers assumed that the message was understood as it was intended. The results are discussed in the context of two theoretical accounts for these perspective-taking errors: the “knowledge projection hypothesis,” which appeals to readers’ expectations about cooperative behavior during communication, and “construal,” which attributes the illusory transparency of intention to a general cognitive bias that occurs during the perception of ambiguous stimuli.  相似文献
