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

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

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

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

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

The primary purposes of the present study were to examine age differences in adaptive decision making and to evaluate the role of numeracy in mediating the relationship between age and adaptive decision making. Adaptive decision making was assessed by the Cups task (Levin, Weller, Pederson, & Harshman, 2007 Levin , I. P. , Weller , J. A. , Pederson , A. A. , & Harshman , L. A. ( 2007 ). Age-related differences in adaptive decision making: Sensitivity to expect value in risky choice . Judgement and Decision Making , 2 ( 4 ), 225233 .[Web of Science ®] [Google Scholar]). Forty-six younger (18 to 24 years old) and 37 older adults (61 to 89 years old) completed the Cups task. In addition, the Numeracy Scale (Lipkus, Samsa, & Rimer, 2001 Lipkus , I. M ., Samsa , G. , & Rimer , B. K. ( 2001 ). General performance on a numeracy scale among highly educated samples . Medical Decision Making , 21 ( 1 ), 3744 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) was used to measure individual numeric ability. Adaptive decision making was operationalized by the Expected Value sensitivity (i.e., the product of probability and outcome magnitudes) across the gain and the loss domains. Older adults had significantly lower Expected Value sensitivity than young adults. In addition, older adults demonstrated significantly lower numeracy than younger adults. Finally, numeracy partially mediated the relationship between age and adaptive decision making. It is suggested that older adults’ declined decision making may be partially due to their declined numeric abilities. Implications were discussed in numeracy education and public policies concerning older adults.  相似文献

Tasks of word reading in Chinese and English; nonverbal IQ; speeded naming; and units of syllable onset (a phoneme measure), syllable, and tone detection awareness were administered to 211 Hong Kong Chinese children ages 4 and 5. In separate regression equations, syllable awareness was equally associated with Chinese and English word recognition. In contrast, syllable onset awareness was uniquely associated with English reading only, whereas tone detection was uniquely associated with Chinese reading only. Results underscore both the universality of first-language phonological transfer to second-language reading and the importance of different psycholinguistic units (Ziegler & 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(1): 329. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) for understanding reading acquisition: Tone units are integral to Chinese character recognition, whereas phonemes are more strongly associated with English word recognition, even within the same children.  相似文献

Oshima, Raju, Flowers, and Slinde (1998) Oshima, T. C., Raju, N. S., Flowers, C. P. and Slinde, J. A. 1998. Differential bundle functioning using the DFIT framework: Procedures for identifying possible sources of differential functioning. Applied Measurement in Education, 11: 353369. [Taylor & Francis Online], [Web of Science ®] [Google Scholar] 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 Raju, N. S., van der Linden, W. J. and Fleer, P. F. 1995. IRT-based internal measures of differential functioning of items and tests. Applied Psychological Measurement, 19: 353368. [Crossref], [Web of Science ®] [Google Scholar]). 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

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.

In a national evaluation of environmental literacy in Israel, (Negev, Sagy, Garb, Salzberg, & Tal, 2008 Negev, M., Sagy, G., Garb, Y., Salzberg, A. and Tal, A. 2008. Evaluating the environmental literacy of Israeli elementary and high school students. Journal of Environmental Education, 39(2): 320. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]), 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

Human beings have a fundamental need to belong, for ongoing positive interactions with others who provide companionship and caring (Baumeister & Leary, 1995 Baumeister, R. F., & Leary, M. R. (1995). The need to belong: Desire for interpersonal attachments as a fundamental human motivation. Psychological Bulletin, 117, 497529. doi: 10.1037/0033-2909.117.3.497.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). Children may hit, exclude, or harass others electronically because when their own needs for belongingness are threatened, or when they want to enhance their own status, they lash out and hurt others in the way they think will be most painful, by engaging in behaviors that undermine the target's sense of belongingness. For reasons discussed herein, children and adolescents might be especially vulnerable to desperate needs for belongingness. Viewing bullying as motivated by the need to belong has profound implications for prevention and intervention programs to reduce bullying.  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 Walton, G. M. and Spencer, S. J. 2009. Latent ability: Grades and test scores systematically underestimate the intellectual ability of negatively stereotyped students. Psychological Science,, 20,: 11321139. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]). 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

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

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

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

This rejoinder provides comment on issues raised by Schwartz, Hobsbaum, Briggs and Scull (2009 Schwartz, R. M., Hobsbaum, A., Briggs, C. and Scull, J. 2009. Reading Recovery and evidence‐based practice: A response to Reynolds and Wheldall (2007). International Journal of Disability, Development and Education, 56(1): 515. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) in their article about evidence‐based practice and Reading Recovery (RR), written in response to Reynolds and Wheldall (2007 Reynolds, M. and Wheldall, K. 2007. Reading Recovery twenty years down the track: Looking forward, looking back. International Journal of Disability, Development and Education, 54: 199223. [Taylor & Francis Online] [Google Scholar]). 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

Bandura's Social Learning Theory purports that early exposure to this social information may have an impact on children's schema development (e.g., Bandura, 2001 Bandura , A. ( 2001 ). Social cognitive theory: An agentic perspective . Annual Review of Psychology , 52 , 126 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), which may influence how children and later adults think about what it means to age and get older (e.g., what it means to be an aging woman in society). By extension, if the portrayal of aging women characters in picture books contains both ageist and sexist attitudes, then the concern is that learned double jeopardy social schemas may influence both children's and the broader society's reactions to this aging sub-population (Chappell & Havens, 1980 Chappell , N. L. , & Havens , B. ( 1980 ). Old and women: Testing the double jeopardy hypothesis . The Sociological Quarterly , 21 ( 2 ), 157171 .[Crossref], [Web of Science ®] [Google Scholar]) and personal self-efficacy toward aging (Bandura, 2011 Bandura , A. ( 2011 , September). On the functional properties of perceived self-efficacy revisited. Journal of Management pp. 1–37. doi:10.1177/0149206311410606  [Google Scholar]). For the purpose of the current research, a possible double jeopardy portrayal was examined for older women characters in children's picture books. Using a stratified random sampling of 90 children's picture books, results found that older book characters were depicted in only about one-third of the sampled books, and older women portrayals were generally more negative (e.g., “hag”). The current study analyzed the biased aging portrayals in children's picture books, and found evidence for double jeopardy (e.g., both ageist and sexist attitudes combined) in how aging women characters were presented in both text and imagery. Implications toward future research and education interventions that convey more positive messages about aging and being a woman aging in society will be discussed.  相似文献

This article responds to an article by A. Gupta, D. Hammer, and E. F. Redish (2010 Gupta, A., Hammer, D. and Redish, E. F. 2010. The case for dynamic models of learners' ontologies in physics. Journal of the Learning Sciences, 19: 285321. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) that asserts that M. T. H. Chi's (1992 Chi, M. T. H. 1992. “Conceptual change within and across ontological categories: Examples from learning and discovery in science”. In Cognitive models of science: Minnesota studies in the philosophy of science, Edited by: Giere, R. 129186. Minneapolis: University of Minnesota Press.  [Google Scholar], 2005 Chi, M. T. H. 2005. Common sense conceptions of emergent processes: Why some misconceptions are robust. Journal of the Learning Sciences, 14: 161199. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) 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 Slotta, J. D. and Chi, M. T. H. 2006. The impact of ontology training on conceptual change: Helping students understand the challenging topics in science. Cognition and Instruction, 24: 261289. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) 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

Recent findings (Keysar, 1994 Keysar, B. 1994. The illusory transparency of intention: Linguistic perspective taking in text.. Cognitive Psychology, 26: 165208. [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

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 Satorra, A. and Bentler, P. M. 2001. A scaled difference chi-square test statistic for moment structure analysis. Psychometrika, 66: 507514. [Crossref], [Web of Science ®] [Google Scholar]) and new (Satorra & Bentler, 2010 Satorra, A. and Bentler, P. M. 2010. Ensuring positiveness of the scaled chi-square test statistic. Psychometrika, 75: 243248. [Crossref], [Web of Science ®] [Google Scholar]) 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
