Teachers' written reflections on their work, which report on a change in their practice, were the object of this research. Taking teachers' articulation of their plans and actions in teacher journals as our source, this study's aim is twofold: (1) to describe how teacher reflect in a self‐initiated and non‐framed way on their own practice, and (2) to review teacher self generated reflections in reference to models of reflection. In this way, we tried to disclose what precisely teachers write (said) when reflecting on their work (did) in order to appreciate their way of describing what matters in their work; and position this in reference to models that conceptualise (“talk”) on how to actualise (‘walk’) reflection. This ‘double’ articulation of reflection is gauged in two ways, i.e., on: a) completeness, that is, whether it includes relevant components of reflection (models) to be found in the literature, and on b) recursiveness, that is, whether the written account gives evidence of an integrated cyclical, i.e., recursive process of re‐view, which appraises and looks back on what has been accomplished. The results show that teachers do not work along the lines identified in current reflection models (i.e. providing clear problem definition, searching for evidence, planning for change, and reviewing plans). Instead, many teachers use a narrative and valuing appraisal of their accomplishments; not so much cautiously reviewing their actions but prospectively commenting on plans and solutions for future action. The data lead us to be cautious about the prominence of reflection models as advocated in the literature to be applied to teachers' written accounts of their practice. 相似文献

This article describes English language proficiency and bilingual verbal ability for a sample of 209 students aged 10 to 16 from three immigrant groups—Chinese, Dominican, and Haitian. Sources of data included structured student interviews, parent interviews, and individual language assessments. On average, students' English language proficiency was far below their age and grade level with significant differences among the groups. Estimates of students' language ability improved once their skills in their first language were considered as demonstrated by the bilingual verbal ability scores. Results from this study demonstrate the need to consider both English and first language skills in assessing the language abilities of these students and in promoting educational access and equity for recent immigrants. 相似文献

This article investigates the role of autoethnographic research as the methodological tool of choice for a Chicana who positions herself along the liminal perspective. I posit that testimonios, autobiographical educational experiences, must be used as valid ethnographic research to contribute to existing knowledge around issues of educational equity. Producing autoethnographic research acknowledges and validates my Chicana presence as well as draws attention to my marginal position inside dominant structures of education. Autoethnography and critical race theory are the manners in which I think about the world and the ways I have chosen to engage in educational research. My work is derived from personal experience in Los Angeles urban schools and later in elite institutions of higher education. These distinct locations present a unique opportunity to problematize the internalized forms of class and racial structures that permeate educational institutions. Grounded in my own educational biography, testimonios frame my research perspective to interrogate the role that educational institutions play in the creation of particular ideologies in working-class students of color. 相似文献

Research in the field of attribution theory and academic achievement suggests a relationship between a student's attributional style and achievement. Theorists and researchers contend that attributions influence individual reactions to success and failure. They also report that individuals use attributions to explain and justify their performance. Studies in mathematics education identify attribution theory as the theoretical orientation most suited to explain academic performance in mathematics. This study focused on the relationship among a high risk course, low success rates, and attribution by examining the difference in the attributions passing and failing students gave for their performance in College Algebra. Students from a large urban community college in South Florida (n = 410) self-reported their performance on an in-class test by providing open-ended attribution statements to explain the cause of their performance. They then attributed their performance along the dimensions of locus of causality, stability, personal controllability, and external controllability using the Causal Dimensions Scale (CDSII). The open-ended attribution statements were coded in relation to ability, effort, task difficulty, and luck and compared using a Pearson chi- square procedure. The quantitative data compared the passing and failing groups and their attributions for performance on the test using One-way ANOVA and Pearson chi-square procedures. The results of the quantitative data comparing passing and failing groups and their attributions along the dimensions measured by the CDSII indicated statistical significance in locus of causality, stability, and personal controllability. The results comparing the open-ended attribution statements indicated statistical significance in the categories of effort and task difficulty. 相似文献

Millions of dollars are spent annually on professional development, and designers of training events recognize they must demonstrate to all stakeholders the value added by these programs. The purpose of this study was to measure the learning that occurred during professional development seminars for community college academic department chairs. The research question was the following: What increases in knowledge and skills did program participants attribute to their training experience? Using Alliger and Janak's model for levels of learning as a conceptual framework, data were collected through a preliminary questionnaire on learning needs, session and overall evaluations, and a retrospective pretest addressing 35 knowledge and skill areas. Statistical analysis of retrospective pretest results for six areas identified by participants as priorities indicated that participants felt learning had occurred as a result of the seminar (significant at .0001 level). The retrospective pretest instrument was deemed an effective tool for evaluating learning in continuing education offerings, higher education professional development events, and similar settings. 相似文献

Several investigators have interpreted method effects associated with negatively worded items in a substantive way. This research extends those studies in different ways: (a) it establishes the presence of methods effects in further populations and particular scales, and (b) it examines the possible relations between a method factor associated with negatively worded items and several covariates. Two samples were assessed: 592 high school students from Valencia (Spain), and 285 batterers from the same city. The self-esteem scales used were Rosenberg's Self-Esteem Scale, the State Self-Esteem Scale, and Self-Esteem 17. Anxiety was also assessed with the State-Trait Anxiety Inventory, and gender and educational level were taken into account. The models were conducted using a multiple indicators and multiple causes (MIMIC) model framework. The evidence in this research pointed out that method effects were present across the different measures of self-esteem. Moreover, a significant and negative effect of anxiety on method effects was present across scales and samples, whereas no effects of age or educational level where found. 相似文献

Abstract Within education, some teachers’ interpretation of professionalism emphasizes conformity to the perceived norms of collective associations. Unprofessional behaviour, often equated with ‘unethical’ behaviour, is seen by many to be that which threatens solidarity and loyalty to colleagues. Informal norms typified by casual collegial relations as well as more formal attachments to organized unions or teachers’ federations exert a significant influence on individuals’ behaviour within the group. Professional ethics, in this sense, become concerned primarily with how one relates to colleagues rather than how one fulfils moral responsibilities to students. Qualitative findings from interviews with elementary and secondary school teachers suggest that, as a result of an ethic of collegial loyalty, some teachers experience personal moral and ethical dilemmas that they find difficult to resolve. Some respondents acknowledged that this can enable serious situations to be ignored or ‘covered up’. This paper examines some of the tensions and dilemmas experienced by teachers and raises questions about the ethical adequacy of defining professionalism in terms of inter‐colleague behaviour. 相似文献

The old urban centres are marks of an historical and architectural heritage that should be protected and safeguarded. For such, it is fundamental to have a complete understanding of the genesis, regarding both building and the urban mesh. This fact is essential to the support of qualified, conscientious and sustainable rehabilitation interventions on the old building stock. The research carried out addresses the issue of the old urban centres from the perspective of the analysis and inventory of buildings features. The cataloguing process of the building typologies is presented in this work as a synthesis of the principal construction forms, with the old city centre of Seixal being used as a case study. The identification of building typologies has supported a seismic and fire vulnerability assessment of the old building stock. The assessment methodologies developed and used are based on the detailed survey and building inspection, therefore the building typology cataloguing is essential in the analysis at such a large scale. Then we discussed the strategy for the conservation actions incorporated in a broader risk management policy. 相似文献

This research investigates the stability of rock slopes in the foundations of selected medieval castles in Slovakia. In the first phase, static analysis of the 45 selected medieval castle rock slopes was performed, where more than 12,000 potentially unstable blocks were analyzed and the factor of safety in static condition was calculated using the key block theory implemented in the Kbslope module of PTworkshop software. Based on results of the static stability analysis, a pseudo-static analysis was performed adopting the seismic acceleration in accordance with Slovak Technical Standards – Seismic actions on structures. This was implemented by calculating the vectors of horizontal force acting upon shear failure in the direction of the slope face with a zero vertical component. When non-finite and tapered blocks were ignored, the results proved that 14% of the 12,217 blocks investigated under static conditions could be considered unstable. This number increased to 23% under pseudo-static conditions, when seismic acceleration was implemented in the stability calculations. A detailed stability assessment of the Gymes Castle located in western Slovakia was carried out with delineation of blocks prone to rock sliding and proper stabilization methods, based on joint sets orientation measurements performed on the 3D point cloud generated by laser scanner. 相似文献
