This paper is centered on creating equitable opportunities for learners in mathematics education. Through observations of teacher practice, the paper seeks to theorize how teachers enact their dispositions toward mathematics instruction. These observed propensities, in relation to teachers’ aims for students to “take up their space” in and beyond the mathematics classroom, then inform a model of equitable mathematics instruction. Teachers’ dispositions are considered in relation to Mason’s discipline of noticing and Bourdieu’s notion of the symbolic violence of dominant discourses.  相似文献

International University Education: An Australian Perspective   总被引:1,自引:1,他引:0  
This paper attempts to explore the effectiveness of UK universities' websites. The area of branding in higher education has received increasing academic investigation, but little work has researched how universities demonstrate their brand promises through their websites. The quest to differentiate through branding can be challenging in the university context, however. It is argued that those institutions that have a strong distinctive image will be in a better position to face a changing future. Employing a multistage methodology, the web pages of 20 UK universities were investigated by using a combination of content and multivariable analysis. Results indicated ‘traditional values’ such as teaching and research were often well communicated in terms of online brand but ‘emotional values’ like social responsibility and the universities' environments were less consistently communicated, despite their increased topicality. It is therefore suggested that emotional values may offer a basis for possible future online differentiation.  相似文献

Accumulating evidence suggests children enrolled in full-time child care often display afternoon elevations of the hormone cortisol, which is an indicator of stress. Recent advances in immunoassays allow for measurement of activity in the hypothalamic–pituitary–adrenal axis and the autonomic sympathetic nervous system from saliva, and measurement of both systems provides a more complete understanding of activity in the stress response system. This study is the first to examine both cortisol and alpha-amylase in children attending child care and focuses on the influences of specific indicators of classroom process quality. A diverse sample of 63 preschool children nested in 14 classrooms of varying quality participated in this study; child salivary cortisol and alpha-amylase were collected at six times over 2 days. Results indicate that children in classrooms with higher Emotional Support displayed a greater decline in cortisol from morning to afternoon. Further, children in classrooms with higher Emotional Support exhibited lower total alpha-amylase output while attending child care. Implications for professional development for early childhood teachers and measurement of classroom quality are discussed.  相似文献

This research explored the measurement characteristics of two science examinations and the potential to use access arrangements data to investigate how students requiring reading support are affected by features of exam questions. For two science examinations, traditional and Rasch analyses provided estimates of difficulty and information on item functioning. For one examination, the performance of students eligible for support from a reader in exams was compared to a ‘norm’ group. For selected items a sample of student responses were analysed. A number of factors potentially making questions easier, more difficult or potentially contributing to problems with item functioning were identified. A number of features that may particularly influence those requiring reading support were also identified.  相似文献

At a time when government funding cuts mean that public libraries face an uncertain future and need to make sure they stay relevant to young users and their families, this paper explores what counts as literacy for young children in a public library in a town in the East Midlands, UK. It is based on a study which adopted an ethnographic approach, drawing on Lefebvre's spatial theory to understand how a library space presents literacy to young children and their carers, and how this then shapes the literacy practices and events that happen in this space. The study shows that dominant discourses are bound up in what the library staff understand to be their role in promoting and supporting young children's literacy, and that, often, they organise the space and literacy events in ways that reflect these discourses. However this paper argues that it is not only the library staff that create space in the library, as carers and their children are sometimes seen to create alternative spaces which challenge and subvert the way the librarians would like the space to be used and understood.  相似文献

Multi-document discourse parsing aims to automatically identify the relations among textual spans from different texts on the same topic. Recently, with the growing amount of information and the emergence of new technologies that deal with many sources of information, more precise and efficient parsing techniques are required. The most relevant theory to multi-document relationship, Cross-document Structure Theory (CST), has been used for parsing purposes before, though the results had not been satisfactory. CST has received many critics because of its subjectivity, which may lead to low annotation agreement and, consequently, to poor parsing performance. In this work, we propose a refinement of the original CST, which consists in (i) formalizing the relationship definitions, (ii) pruning and combining some relations based on their meaning, and (iii) organizing the relations in a hierarchical structure. The hypothesis for this refinement is that it will lead to better agreement in the annotation and consequently to better parsing results. For this aim, it was built an annotated corpus according to this refinement and it was observed an improvement in the annotation agreement. Based on this corpus, a parser was developed using machine learning techniques and hand-crafted rules. Specifically, hierarchical techniques were used to capture the hierarchical organization of the relations according to the proposed refinement of CST. These two approaches were used to identify the relations among texts spans and to generate multi-document annotation structure. Results outperformed other CST parsers, showing the adequacy of the proposed refinement in the theory.  相似文献

It is important for educational assessment bodies to demonstrate how they are seeking to meet the demands of validity. The approach to validity taken here assumes a ‘consequentialist’ view where the appropriacy of the inferences made on the basis of assessment results is seen as central. This paper describes the development of a systematic approach to the collection of evidence that can support claims about validity for general qualifications. An operational framework was developed drawing on Kane (2006 Kane, M.T. 2006. “Validation”. In Educational measurement, 4th ed., Edited by: Brennan, R.L. 1764. Westport, CT: Praeger.  [Google Scholar]). The framework involves a list of inferences to be justified as indicated by a number of linked validation questions. For each question various data would be gathered to provide ‘evidence for validity’ and to identify any ‘threats to validity’. The structure is designed to be accessible for operational users. This paper describes the development of the proposed framework and the types of methods to be used to gather relevant evidence.  相似文献

Despite the increasing popularity of doctoral education, many students do not complete their studies, and very little information is available about them. Understanding why some students consider that they do not want to, or cannot, continue with their studies is essential to reduce dropout rates and to improve the overall quality of doctoral programmes. This study focuses on the motives students give for considering dropping out of their doctoral degree. Participants were 724 social sciences doctoral students from 56 Spanish universities, who responded to a questionnaire containing doctoral degree conditions questions and an open-ended question on motives for dropping out. Results showed that a third of the sample, mainly the youngest, female and part time students, stated that they had intended to drop out. The most frequent motives for considering dropping out were difficulties in achieving a balance between work, personal life and doctoral studies and problems with socialization. Overall, results offer a complex picture that has implications for the design of doctoral programmes, such as the conditions and demands of part-time doctoral studies or the implementation of educational proposals that facilitate students’ academic and personal integration into the scientific community in order to prevent the development of a culture of institutional neglect.  相似文献

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years. Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1 amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech stimuli. The early development of biologically based differences in the perception and processing of auditory information contributes to later group differences in reading proficiencies at school age.  相似文献
