The authority of the nation states and their capacity to govern their education policy has been reconfigured by the processes of globalisation. This paper examines recent education policy in Pakistan in order to reveal the nature of national authority in education policy-making in a challenging context. The central piece of analysis is the pre-policy text issued by the Ministry of Education, Pakistan — the White Paper. This analysis is further supported through interviews with senior policy actors and other significant policy texts. The paper identifies several tensions caused by the interaction of global and national education policy priorities and explores how the national government of Pakistan seeks to expand its SoA through ‘soft’ governance approaches despite the material and financial constraints within which it operates. 相似文献

Many institutions encourage formative computer‐based assessment (CBA), yet competing priorities mean that learners are necessarily selective about what they engage in. So how can we motivate them to engage? Can we facilitate learners to take more control of shaping their learning experience? To explore this, the Learning with Interactive Assessment (LINA) project, a small‐scale study, trialed a selection of online, interactive question features designed to increase motivation, particularly of work‐based learners, and to enhance learners' ability to self‐regulate their own learning experience. We present initial findings on learner perceptions of: (1) a confidence indicator tool—for learners to indicate their confidence that their answer will be correct before answering a question; (2) a learning log—for learners to insert reflections or view system‐recorded information about their learning pathway; and (3) question feedback—for displaying a range of author comments. Themes emerged relating to motivational, behavioural and cognitive factors, including risk taking and skills in self‐assessment. A serendipitous finding highlights learners' frequently not reading onscreen feedback and presents perceptions on when feedback becomes most useful. Motivators and barriers to engagement and self‐regulation are discussed in relation to principles of best feedback practice. 相似文献

In this paper, we aim to contribute to the discussion of the role of the human body and of the concrete artefacts and signs created by humankind in the constitution of meanings for mathematical practices. We argue that cognition is both embodied and situated in the activities through which it occurs and that mathematics learning involves the appropriation of practices associated with the sets of artefacts that have historically come to represent the body of knowledge we call mathematics. This process of appropriation involves a coordination of a variety of the semiotic resources??spoken and written languages, mathematical representation systems, drawings, gestures and the like??through which mathematical objects and relationships might be experienced and expressed. To highlight the connections between perceptual activities and cultural concepts in the meanings associated with this process, we concentrate on learners who do not have access to the visual field. More specifically, we present three examples of gesture use in the practices of blind mathematics students??all involving the exploration of geometrical objects and relationships. On the basis of our analysis of these examples, we argue that gestures are illustrative of imagined reenactions of previously experienced activities and that they emerge in instructional situations as embodied abstractions, serving a central role in the sense-making practices associated with the appropriation of mathematical meanings. 相似文献

A cross‐cultural examination of the impact of social,organisational and individual factors on educational technology acceptance between British and Lebanese university students 下载免费PDF全文

This paper examines the social, organisational and individual factors that may affect students' acceptance of e‐learning systems in higher education in a cross‐cultural context. A questionnaire was developed based on an extended technology acceptance model (TAM). A total sample of 1173 university students from two private universities in Lebanon and one university in England participated in this study. After performing the satisfactory reliability and validity checks, the hypothesised model was estimated using structural equation modeling. The findings of this study revealed that perceived usefulness (PU), perceived ease of use (PEOU), social norms (SNs), perceived quality of work life (QWL), computer self‐efficacy (SE) and facilitating conditions (FC) are significant determinants of behavioural intentions (BIs) and usage of e‐learning system for the Lebanese and British students. QWL, the newly added variable, was found the most important construct in explaining the causal process in the model for both samples. Differences were found between Lebanese and British students with regard to PEOU, SN, QWL, FC, SE and actual usage; however, no differences were detected in terms of PU and BI. Overall, the proposed model achieves acceptable fit and explains for 69% of the British sample and 57% of the Lebanese sample of its variance which is higher than that of the original TAM. Our findings suggest that individual, social and organisational factors are important to consider in explaining students' BI and usage of e‐learning environments. 相似文献

Chemotherapy drugs, used for prevention of uncontrolled cell proliferation in certain tissues as well as inducing apoptosis in tumor cells, are important candidates for treatment of cancer. The synthesized 2-amino-4H-chromene-3-carbonitrile derivatives effective on cancerous cells resistant to other drugs such as Paclitaxel were used due to their ability in induction of apoptosis. The growth inhibitory and inducing apoptosis activities were determined. In order to make it target-oriented, the best compound was conjugated with gold nanoparticles (NPs) by aspartic acid with chemical reduction method. Cytotoxicity effect of 2-amino-4H-chromene-3-carbonitrile derivatives against the T47D breast cancer cell line was determined by MTT assay. The synthesis of gold NPs was confirmed by transmission electron microscopy, UV–Vis and dynamic light scattering. To assess the effects of compounds on the process of apoptosis, staining methods with acridine orange–ethidium bromide and Hoechst staining by fluorescence microscopy and DNA fragmentation by the diphenylamine method were used. The synthesized compounds containing two NH2 groups on benzene rings, demonstrated more cytotoxicity effect. The effect of conjugation with gold NPs and the induction of apoptosis were studied with the best compound. The cytotoxicity effects of the synthesized 2-amino-4H-chromene-3-carbonitrile compounds were changed by replacement of NO2 group on thiol ring with different chemical groups on the benzene ring. Analyses of treated cell lines by conjugated and non-conjugated forms of compounds verified their ability in inducing apoptosis while conjugated form demonstrated higher apoptosis. 相似文献

While theories and recommendations continue to proliferate in the educational research literature on what it means to teach towards social justice and to prepare teachers for such teaching, so do concerns that these theories and recommendations fail to account for the ways that the contexts of teaching—cultural contexts, national contexts, political contexts—always affect teaching in idiosyncratic, unpredictable and even contradictory ways. Given that much educational research fails to trouble the US‐centric nature of prevailing conceptions of social justice and teacher education, it is important to learn about the unique as well as shared challenges facing teacher educators around the globe. In this article, teacher educators from Asia, Africa, North America and South America offer a sampling of initiatives in anti‐oppressive teacher education; that is, initiatives to prepare teachers to teach various subject matters to various age groups, addressing various forms of oppression in various cultural and community contexts. 相似文献

One of the main applications of citation is to find articles that are relevant to a particular article. However, not all citations are equally relevant to the target article. This paper presents an approach to identify the most relevant citation(s). To this end, the Normalized Similarity Index (NSI) is proposed to quantify the similarity between the source and target of a citation base on the co-citations and references shared by them. To validate the method, NSI was calculated for five citation networks and was compared with the peer review grades for the relevancy between the source and the target articles. The results showed a significant correlation between the NSI ranks and those of peer review. Also, combined linkage (CL) and weighted direct citation (WDC) were calculated from the same data. According to the results of comparison between the NSI with other similarity measures, in most cases, NSI did better than others at reproducing the peer rankings. Our principal conclusion is that the NSI can be used to prioritize the citations of given highly cited article, and represent knowledge flow from the target article. 相似文献

The primary purpose of this study was to investigate the combined and partial effects of the Integrated Reading/Study Strategy
and Conceptual Physics Approach on ninth grade private high school students’ achievement in and attitudes toward optics. The
Integrated Reading/Study Strategy is a new strategy which was developed by integrating previously existing reading strategies
of the KWL and SQ3R with classroom lecturing. The Conceptual Physics Approach is an instructional strategy developed on the
basis of Conceptual Physics suggested by Paul G. Hewitt. To investigate the partial and combined effects of methods, factorial
design was used. The study was conducted with 124 students from two private high schools in the ?ankaya district region of
Ankara, Turkey. Various teaching/learning materials were developed and used for the study. Two measuring tools, Achievement
Test about Optics and Attitude Scale about Optics were used as pre and post tests before and after instruction. The study
continued for a two-month treatment period. The results of the study showed that the combined effect of the Integrated Reading/Study
Strategy and Conceptual Physics Approach improved students’ achievement significantly compared to the separate individual
methods. Although the product of the Integrated Reading/Study Strategy and Conceptual Physics Approach increased students’
attitudes more compared to the remaining methods, the result is not statistically significant. 相似文献
