This article develops a multimodal model for how claims and evidence work across linguistic, numeric, and visual modes in the professional writing of environmental scientists. I coded and analyzed two reports (Bacey &; Barry, 2008 Bacey , J. , &; Barry , T. ( 2008 ). A comparison study of the proper use of Hester-Dendy® samplers to achieve maximum diversity and population size of benthic macroinvertebrates Sacramento Valley, California (Report No. EH08-2) . Sarcramento , CA : California Environmental Protection Agency . [Google Scholar]; Levine et al., 2005 Levine , J. , Kim , D. , Goh , K. S. , Ganapathy , C. , Hsu , J. , Feng , H. , &; Lee , P. ( 2005 ). Surface and ground water monitoring of pesticides used in the Red Imported Fire Ant Control Program (Report EH05-02) . Sacramento , CA : California Environmental Protection Agency . [Google Scholar]) written by research scientists working for California's Department of Pesticide Regulation (DPR) by applying concepts from studies of argument, genre, and visual representations in science. The claim-evidence patterns show initial and summative claims as well as warrants being presented in linguistic forms; however, supporting evidence (i.e., data and backing) is found in numeric, visual, and linguistic forms. These findings highlight the need to extend Toulmin's understanding of claim-evidence relationships into a more robust multimodal model.  相似文献

Drawing from a 14-month ethnographic study at an elementary school in the US South, I examine the role that the gifted and talented (GT) program played in racial socialization at the school. I use the principle of Whiteness as property (Harris, 1995 Harris, C. I. (1995). Whiteness as property. In K. Crenshaw, N. Gotanda, G. Peller, &; K. Thomas (Eds.), Critical race theory: The key writings that formed the movement (pp. 276291). New York, NY: New Press. [Google Scholar]) to analyze space as curriculum, the physical and social spaces of a school that structure how particular student bodies are positioned in relation to power and privilege. I argue that the segregated GT structure perpetuates racial inequities that young children are taught to accept and emulate. I conclude with implications for practice and future studies about the role of GT in racial socialization.  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 Satorra, A. and Bentler, P. M. 1988. “Scaling corrections for chi-square statistics in covariance structure analysis”. In ASA 1988 Proceedings of the Business and Economic Statistics Section, 308313. Alexandria, VA: American Statistical Association.  [Google Scholar], 1994 Satorra, A. and Bentler, P. M. 1994. “Corrections to test statistics and standard errors in covariance structure analysis”. In Latent variables analysis: Applications for developmental research, Edited by: von Eye, A. and Clogg, C. C. 399419. Thousand Oaks, CA: Sage.  [Google Scholar]), was to account for the effect of nonnormality. Muthén (1993) Muthén, B. O. 1993. “Goodness of fit with categorical and other nonnormal variables”. In Testing structural equation models, Edited by: Bollen, K. A. and Long, J. S. 205234. Newbury Park, CA: Sage.  [Google Scholar] 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

ABSTRACT

Deep reading comprehension refers to the process required to succeed at tasks defined by the Common Core State Literacy Standards, as well as to achieve proficiency on the more challenging reading tasks in the Program for International Student Assessment (PISA) framework. The purpose of this study was to test the hypothesis that three skill domains not frequently attended to in instruction or in theories of reading comprehension—academic language, perspective taking, and complex reasoning—predict outcomes on an assessment of deep reading comprehension. The Global Integrated Scenario-based Assessment (GISA; O'Reilly, Weeks, Sabatini, Halderman, & Steinberg, 2014 O'Reilly T., Weeks, J., Sabatini, J., Halderman, L., & Steinberg, J. (2014). Designing reading comprehension assessments for reading interventions: How a theoretically motivated assessment can serve as an outcome measure. Educational Psychology Review, 26, 403424. doi:10.1007/s10648-014-9269-z[Crossref], [Web of Science ®] [Google Scholar]) is designed to reflect students' abilities to evaluate texts, integrate information from an array of texts, and use textual evidence to formulate a position, all features of deep reading comprehension. We tested the role of academic language, perspective taking, and complex reasoning in explaining variance in end-of-year GISA scores, controlling for beginning-of-year scores and student demographics. All three predictors explained small, but significant, amounts of additional variance. We suggest that these three skill domains deserve greater attention in theories of reading comprehension and in instruction.  相似文献

This paper reflects on the ongoing debate surrounding the usefulness (or otherwise) of multiple‐choice questions (MCQ) as an assessment instrument. The context is a graduate school of business in Australia where an experiment was conducted to investigate the use of assertion‐reason questions (ARQ), a sophisticated form of MCQ that aims to encourage higher‐order thinking on the part of the student. It builds on the work of Connelly (2004 Connelly, L. B. 2004. “Assertion‐reason assessment in formative and summative tests: results from two graduate case studies”. In Educational innovation in economics and business VIII: pedagogy, technology and innovation, Edited by: Ottewill, R., Borredon, E., Falque, L., Macfarlane, B. and Wall, A. 359378. Dordrecht: Kluwer Academic Publishers.  [Google Scholar]) which produced a quantitative analysis of the use of ARQ testing in two economics course units in a flexibly‐delivered Master of Business Administration (MBA) program. Connelly's main findings were that ARQ tests were good substitutes for the more conventional type of multiple‐choice/short‐answer type questions and, perhaps more significantly, ARQ test performance was a good predictor of student performance in essays—the assessment instrument most widely favoured as an indicator of deeper learning. The main focus of this paper is the validity of the second of these findings, analysis of questionnaire data casting some doubt over whether student performance in ARQ tests can, indeed, be looked upon as a sound indicator of deeper learning—student reactions and opinions suggesting instead that performance might have more to do with one's proficiency in the English language.  相似文献

The Progress in International Reading Literacy Study (PIRLS) 2006 findings highlighted concerns about reading literacy teaching quality in South African primary schools (Howie et al., 2007 Howie, S.J., Venter, E., Van Staden, S., Zimmerman, L., Long, C., Scherman, V. and Archer, E. 2007. Progress in International Reading Literacy Study (PIRLS) 2006 summary report. South African children's reading literacy achievement, Pretoria, South Africa: Centre for Evaluation and Assessment, University of Pretoria.  [Google Scholar]). In response, the national Department of Education (DoE, 2008a, 2008b, 2008c, 2008d) has emphasised instructional practice improvement. However, little emphasis has been placed on the role of school organisation in learners’ reading success or failure. This article presents school organisation findings from a mixed methods study that explored South African Grade 4 teachers’ instruction practices and schooling conditions for reading literacy development. The analysis considered is based on the reclassification of the PIRLS 2006 sample according to class achievement levels on the PIRLS benchmarks and instructional language profiles. Findings from the PIRLS 2006 school questionnaire data are reported together with findings from case studies to illustrate differences and similarities in school organisation for reading literacy across a range of low- and high-performing schools.  相似文献

This study compared the impact of 2 types of small-group interventions targeting below-level 3rd-grade students. The study compared WordWork decoding and spelling instruction (Calfee, Miller, Norman, Wilson, &; Trainin, 2006 Calfee, R. C., Miller, R. G., Norman, K., Wilson, K., &; Trainin, G. (2006). Learning to do educational research. In M. A. Constas &; R. J. Sterenberg (Eds.), Translating theory and research into educational practice: Developments in content domains, large scale reform, and intellectual capacity (pp. 77103). New York, NY: Routledge. [Google Scholar]; Calfee &; Patrick, 1995 Calfee, R. C., &; Patrick, C. L. (1995). Teach our children well: Bringing K–12 education into the 21st Century. Stanford, CA: Stanford Alumni Assoc. [Google Scholar]), which includes attention to articulation and metacognition, with a more traditional phonological awareness program (Torgesen &; Bryant, 1993 Torgesen, J. K., &; Bryant, B. R. (1993). Phonological awareness training for reading. Austin, TX: Pro-Ed. [Google Scholar]). University education students delivered the interventions with equal instructional time and fidelity, to both groups. Students in both intervention groups engaged in repeated readings of connected text to promote transfer. The impact of training was assessed through decoding, spelling, and oral reading fluency measures. Results indicated that WordWork produced more positive results in decoding, spelling, and fluency, and had significantly fewer treatment resisters.  相似文献

This article builds on scholarship in technical communication, medical rhetoric, and visual communication and represents a portion of a grounded study of one medical workplace setting's visualization practices. Specifically, the author explores how medical images—as technologically and rhetorically rendered artifacts—make “present” (Perelman & Olbrechts-Tyteca, 1969 Perelman , C. , & Olbrechts-Tyteca , L. ( 1969 ). The new rhetoric . Notre Dame , IN : University of Notre Dame Press . [Google Scholar]) the material characteristics of disease and thereby perceptually and argumentatively afford the construction of knowledge about future cancer-care action.  相似文献

The paper discusses the ‘value‐through‐utility’ argument as a key ingredient of environmental educators' interests in traditional ecological knowledge (TEK), and examines some of the epistemological and philosophical tensions it generates in employing TEK within the context of learning with sustainability in mind. In an earlier article (Reid et al., 2002 Reid A Teamey K Dillon J (2002) Traditional ecological knowledge for learning with sustainability in mind Trumpeter: Journal of Ecosophy 18 (1) 27 http://trumpeter.athabascau.ca/content/v18.1/  [Google Scholar]), we argued that it is important to recognize that it is outsiders rather than insiders who usually conceptualize TEK. In this paper, we develop this point further, exploring the theorization and practice of TEK‐based environmental education in the context of discourses about sustainability and environmental education.  相似文献

The authors' aim was to examine the relation between two-digit mental multiplication and working memory. In Study 1, involving 30 fifth-grade students, we used digit span backward as an abbreviated measure of working memory. In Study 2, involving 41 fourth-grade students, working memory comprised measures of phonological loop, visuospatial sketchpad, and central executive (i.e., updating) based on A. Miyake et al. (2000 Miyake, A., Friedman, N. P., Emerson, M. J., Witzki, A. H., Howerter, A., &; Wager, T. D. (2000). The unity and diversity of executive functions and their contributions to complex “frontal lobe” tasks: A latent variable analysis. Cognitive Psychology, 41, 49100.[Crossref], [PubMed], [Web of Science ®] [Google Scholar]). In Study 1, working memory measured through the use of digit span backward explained unique variance in response time. In Study 2, participants' accuracy and response time were most susceptible to phonological loop influence. The findings support the argument that multiplication facts are stored in a verbal form and the retrieval of multiplication facts relies more on verbal modality. Unique features of Chinese mathematics instruction of mental multiplication were discussed. The findings suggested that the involvement of different subcomponents of working memory in mental arithmetic may be subject to instructional, contextual, and linguistic factors.  相似文献

This study reveals the mediation process of mass and interpersonal communication between antecedent political orientation variables and the outcome response variable of political participation. It provides insight into the direct and indirect effects of political communication on political behavior using an advanced social cognitive approach. The study explores the interrelations among political orientations, communication behaviors, and political participation using the theoretical framework of the Orientation 1–Stimulus–Orientation 2–Response model (Markus &; Zajonc, 1985 Markus , H. , &; Zajonc , R. B. ( 1985 ). The cognitive perspective in social psychology . In G. Lindzey &; E. Aronson (Eds.), The handbook of social psychology , (3rd ed. , pp. 137229 ). New York , NY : Random House . [Google Scholar]; McLeod, Kosicki, &; McLeod, 2002 McLeod , J. M. , Kosicki , G. M. , &; McLeod , D. M. ( 2002 ). Resurveying the boundaries of political communication effects . In J. Bryant &; D. Zillman (Eds.), Media effects: Advances in theory and research , (2nd ed. , pp. 215267 ). Mahwah , NJ : Lawrence Elbaum Associates, Inc . [Google Scholar]). A structural equation model was built and supported by 2004 American National Election Survey data. After controlling for demographic variables, both political interest and need for cognition had direct effects on political media use, whereas political interest and need to evaluate had direct effects on interpersonal political discussion. These results suggest that need for cognition and need to evaluate—2 important personality constructs—affect political communication on 2 different levels. Meanwhile, as antecedent orientation variables, political interest, political extremity, and need to evaluate all contribute to political participation. Both political media use and interpersonal discussion directly affect political participation while they also mediate the effect of the political orientation variables on political participation. Furthermore, interpersonal political discussion mediates the effect of political media use on political participation, and political media use mediates the effect of political interest and need for cognition on interpersonal political discussion.  相似文献

I am grateful for this opportunity to reflect on the field of Social Foundations of Education (SFE), in part because it affords an opportunity to advance an historical analysis of the trajectory of the field different from what we provided when my colleagues and I sent to press the Handbook of Research the Social Foundations of Education in 2009 (Tozer, Gallegos, Henry, 2011 Tozer, S. E., & Butts, R. F. (2011). The evolution of social foundations of education. In Tozer, S., Gallegos, B., & Henry, A., (Eds), Handbook of research in the social foundations of education (pp. 114). New York: Routledge. [Google Scholar]). I also welcome the opportunity to acknowledge a particular activist tradition established by earlier generations of Social Foundations scholars who have influenced my work. To quote Stuart Hall, these men and women engaged Social Foundations “as a practice which always thinks about its intervention in a world in which it would make some difference, in which it would have some effect” (in Tozer et?al., 2011 Tozer, S., Gallegos, B., & Henry, A. (2011). (Eds.). Handbook of research in the social foundations of education (p. 11). New York, NY: Routledge. [Google Scholar], p. 11). Finally, this occasion invites a perspective on the equity work in Chicago Public Schools that we have pursued since I introduced it in my AESA Presidential Address in 2006.  相似文献

This paper reports on research on the attitudes of a differentiated sample of students to Catholic schools in general and religious education in particular. Core Catholic youth are described, following Fulton et al. (2000 Fulton, J., Abela, A., Borowik, I., Dowling, T., Marler, P. and Tomasi, L. 2000. Young Catholics at the New Millennium; the Religion and Morality of Young Adults in Western Countries, Dublin: University College Press.  [Google Scholar]: Young Catholics at the New Millennium, Dublin, University College Press), as individuals who have an existing connection with the parish community. Some results that emerge from 58 in‐depth interviews with 14‐ and 15‐year‐old core Catholics are that they value their time in Catholic schools, feel that they are in a safe environment and are not well networked with others of a similar background. Attitudes to religious education by core Catholic youth are described as weak positive. Religious education is not unpopular but is not seen as a discipline that helps resolve some of the difficulties that they experience as young Catholics. These difficulties relate to trying to reconcile what they see as the conflict between the scientific and religious view of creation and many supernatural religious claims.  相似文献

I explore the role of categories as rhetorical barriers in organizations responding to crisis (Veil, 2011 Veil, S. R. (2011). Mindful learning in crisis management. Journal of Business Communication, 48(2), 116147. doi:10.1177/0021943610382294[Crossref] [Google Scholar]). I analyze some problematic categories of the Department of Homeland Security (DHS) and the Federal Emergency Management Agency (FEMA) and the categories’ impact on the organizations’ response to Hurricane Katrina. My analysis shows that unintended and perverse consequences (Giddens, 1984 Giddens, A. (1984). The constitution of society: Outline of the theory of structuration. Cambridge, UK: Polity Press. [Google Scholar], 1987 Giddens, A. (1987). Social theory and modern sociology. Stanford, CA: Stanford University Press. [Google Scholar]) reversed the power of a key legitimated category (Orlikowski, 1995 Orlikowski, W. J. (1995). Categories: Concept, content, and context. Computer Supported Cooperative Work, 3, 7378.[Crossref] [Google Scholar]; Giddens, 1984 Giddens, A. (1984). The constitution of society: Outline of the theory of structuration. Cambridge, UK: Polity Press. [Google Scholar]) and exposed a set of reified categories (Giddens, 1984 Giddens, A. (1984). The constitution of society: Outline of the theory of structuration. Cambridge, UK: Polity Press. [Google Scholar]).  相似文献

This study investigated the effect of preschool experience (two types of preschool: Madrasa and non‐Madrasa) on the cognitive development of children in East Africa. In the three countries studied (Kenya, Uganda, and Tanzania/Zanzibar) preschool education is burgeoning and government standards are being set. This quasi experimental evaluation used four subscales (block building, verbal comprehension, early number concept, picture similarities) adapted from the British Ability Scale II (BAS II; discussed by Elliot, Smith and McCulloch in 1996 Elliot, C.D., Smith, P. and McCulloch, K. 1996. British Ability Scale (BAS), Berkshire, , UK: NFER‐NELSON.  [Google Scholar]), and three (verbal meaning, exclusion, closure) from the African Child Intelligence Test (ACIT; discussed by Drenth and colleagues in 1980 Drenth, P.J.D., Van der Vlier, H., Muinde, N.P., Otaala, B., Omari, I.M. and Opolot, J.A. 1980. Jaribio akili mtoto Afrika. [African child intelligence test.] [in Kiswahili], Amsterdam: Free University of Amsterdam.  [Google Scholar]). The development of 423 children was studied at pre‐test (entry to preschool) and at post‐test 18 months later. Hierarchical regression showed that children with both types of preschool experience performed better than the home (comparison) group; however, children attending Madrasa Resource Centre preschools achieved significantly higher scores overall.  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 Flett, G., Hewitt, P., Oliver, J. and Macdonald, S. 2002. “Perfectionism in children and their parents: A developmental analysis”. In Perfectionism: Theory, research, and treatment, Edited by: Flett, G. and Flett, P. 89132. Washington, DC: American Psychological Association. [Crossref] [Google Scholar]). 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

The authors compare three teachers' adaptations and implementation of a lunar modeling lesson to explain marked differences in student learning outcomes on a spatial-scientific lunar assessment. They used a modified version of the Practices of Science Observation Protocol (P-SOP; Forbes, Biggers, &; Zangori, 2013 Forbes C., Biggers, M., &; Zangori, L. (2013). Investigating essential characteristics of scientific practices in elementary science learning environments: The practices of science observation protocol (P-SOP). School Science and Mathematics, 113, 180190.[Crossref] [Google Scholar]) to identify ways in which features of inquiry were emphasized in each classroom. Additionally, classroom communities of practice were categorized as task-based or practice-based (Riel &; Polin, 2004 Riel, M. &; Polin, L. (2004). Learning communities: Common ground and critical differences in designing technical support. In S. Barab, R. Kling, &; J. Gray (Eds.), Designing for virtual communities in the service of learning (pp. 1652). Cambridge, MA: Cambridge University Press.[Crossref] [Google Scholar]). The authors found that student learning outcomes were related to the fidelity with which the teachers implemented the lesson. Teachers with higher P-SOP scores fostered more of a practice-based learning community than task-based one, which also paralleled greater student learning gains. Although the students' scores did not differ by teacher on the preassessment, they did differ significantly on the postassessment, indicating that the curricular choices and learning communities developed by the teachers impacted what students were able to learn.  相似文献

How does one grade an electronic portfolio? This question is one I have thought about, have enacted, and have written about, primarily in reference to ePortfolios used in writing classrooms (Yancey, McElroy, & Powers, 2013 Yancey, K. B., McElroy, S., & Powers, E. (2013). Composing, networks, and electronic portfolios: Notes toward a theory of assessing ePortfolios. In D. DeVoss & H. McKee (Eds.), Digital writing assessment and evaluation. Computers and composition. Logan, UT: Digital Press/Utah State University Press. [Google Scholar]). But what happens when the content and developmental levels are changed, in this case from an undergraduate first-year writing class to another required class, this one offered at the graduate level, Digital Revolution and Convergence Culture? Is using a scoring guide, the preferred approach in writing classes, the best approach in this new context? Or, following Moss, Girard, and Haniford (2006 Moss, P., Girard, B., & Haniford, L. (2006). Validity in educational assessment. Review of research in education 30, 109162.[Crossref], [Web of Science ®] [Google Scholar]), could one use outcomes to “stage a conversation” around a student's ePortfolio; if so, what might a staged conversation look like? Or what might happen if instead of using outcomes as a framework, students themselves set the terms for that conversation? Here, I consider these options, attending especially to the importance of making good judgments and of fostering learning.  相似文献

This study examined the beliefs of in-service teachers working in inclusive classrooms regarding developmentally appropriate practices and how those beliefs affected their attitudes toward, knowledge of, and comfort levels regarding working with children with disabilities. A mixed-method approach was utilized and data were collected through the use of three survey instruments: Teacher Belief Scale and Instructional Activities Scale (Hart et al., 1990 Hart, C., Burts, D., Charlesworth, P., Fleege, P., Ickes, M. and Durland, M. 1990. The teachers Questionnaire: Preschool version, Baton Rouge, LA: Louisiana State University, School of Human Ecology.  [Google Scholar]) and the In-service Teacher Self-Report Survey (Mitchell, 2002 Mitchell, L. C. 2002. Blending practices in regular education: A mixed method design study on course practicum and training experiences in relation to preservice teacher attitudes and knowledge about inclusion. Dissertation Abstracts International, 5: A63 (UMI No. 726467131). [Google Scholar]). Data were also collected through open-ended questions to assess Teachers' perceived level of preparation for the inclusive classroom. This study also examined whether education or experience levels had an influence on Teachers' perceptions regarding inclusive practices. Results of the study indicate that there is not a significant relationship between in-service Teachers' beliefs regarding developmentally appropriate practices and their attitudes toward, knowledge of, and comfort levels regarding inclusion. Additionally, results indicate that the Teachers' levels of education or experience do not necessarily indicate that they are prepared to meet the needs of the inclusive classroom environment. Implications regarding the preparation of and ongoing training needs of teachers are discussed.  相似文献

Senior citizens represent the fastest growing demographic worldwide. As indicated in the Year 2000 U.S. Census, there are 35 million people 65 or older in the United States (U.S.). By 2030, it is estimated that there will be about 70 million older adults in the U.S. alone (Chadwick-Dias, McNulty, & Tullis, 2003 Bean , C. & Laven M. (2003). Adapting to seniors: Computer training for older adults. Florida Libraries , 46(2). [Google Scholar]). With the older population growing rapidly and being increasingly exposed to computer technology, it is important that they become informed of what computers can do for them, (e.g., e-mail, document creation, games, and access to information via the Internet) (Shapira, Barak, & Gal, 2007 Parvate , V. & Speicher , S. ( 2004 ). Learning to communicate via the Internet: How senior citizens develop an understanding of electronic communication: A cognitive design study proposal . [Google Scholar]; White, McConnell, Clipp, Branch, Sloane et al., 2002 White , H. , McConnell , E. , Clipp , E. , Branch , L. G. , Sloane , R. , Pieper , C. , & Box , T. ( 2002 ). A randomized controlled trial of the psychosocial impact of providing Internet training and access to older adults . Aging & Mental Health , 6 , 213221 .[Taylor & Francis Online], [Web of Science ®] [Google Scholar]). The longitudinal study presented employs a mixed method data collection and analysis approach that includes the use of standardized surveys, measures of physical fitness and physiology, observations in the retirement community, and structured interviews. Drawing upon Auburn University faculty in the College of Engineering, senior citizens participated in workshops designed to develop their skills in computing. The potential significance of the project was to create a valid and reliable model for outreach to retirement and assisted living communities and other centers for senior citizens.  相似文献
