The paper reports a study that investigated the relationship between students’ self-predicted and actual General Certificate of Secondary Education results in order to establish the extent of over- and under-prediction and whether this varies by subject and across genders and socio-economic groupings. It also considered the relationship between actual and predicted attainment and attitudes towards going to university. The sample consisted of 109 young people in two schools being followed up from an earlier study. Just over 50% of predictions were accurate and students were much more likely to over-predict than to under-predict. Most errors of prediction were only one grade out and may reflect examination unreliability as well as student misperceptions. Girls were slightly less likely than boys to over-predict but there were no differences associated with social background. Higher levels of attainment, both actual and predicted, were strongly associated with positive attitudes to university. Differences between predictions and results are likely to reflect examination errors as well as pupil errors. There is no evidence that students from more advantaged social backgrounds over-estimate themselves compared with other students, although boys over-estimate themselves compared with girls. 相似文献

University‐level courses in science that contain a substantial practicum or laboratory component have always been a problem to deliver through distance education. Because of the potential hazards inherent in the equipment and chemicals commonly used, chemistry is among the more challenging disciplines to teach at a distance. Athabasca University (AU) ‐ Canada's Open University ‐ has been successfully running chemistry courses for over two decades. The development and delivery of AU chemistry courses are described and the approaches that have been developed to meet the challenges of a North American distance‐education university, including the use of new technologies, are discussed. The problems associated with providing distance students with appropriate laboratory experience are also examined. The first‐year general chemistry courses are compared to an equivalent course at a neighbouring traditional university and an analysis of student performance in AU chemistry courses is presented. 相似文献

The present study evaluated the students' psychological well-being, experiences, performance, and perception of learning regional anatomy remotely. A regional anatomy remote learning curriculum was designed and learning materials were delivered virtually to 120 undergraduate medical students at Jinan University, China. All the students consented and voluntarily participated in this study by completing self-administered online questionnaires including the Zung's Self-Rating Anxiety and Depression Scales at the beginning and end of the learning session. A subset participated in focus group discussions. Most of the students (90.0%) positively evaluated the current distance learning model. More than 80% were satisfied with the content arrangement and coverage. Many students preferred virtual lectures (68.2%) and videos showing dissections (70.6%) during the distance learning sessions. However, writing laboratory reports and case-based learning were the least preferred modes of learning as they were only preferred by 23.2% and 14.1% of the students, respectively. There was no significant lockdown-related anxiety or depression reported by students using depression and anxiety scales as well as feedback from focus group discussions. The surveyed students' confidence scores in distance learning were significantly higher after 5 weeks than at the beginning of the session (3.05 ± 0.83 vs. 3.70 ± 0.71, P < 0.05). Furthermore, the present results showed no significant differences between the current group's academic performance in the unit tests as well as the final overall evaluation for different parts of the course compared to that of the previous year's cohort. The findings above were congruent with focus group discussion data that the use of the online teaching platform for regional anatomy significantly improved the students' confidence in virtual and self-directed learning and did not negatively affect their academic performance. 相似文献

This paper analyzes the productivity development in the German public theater sector for the seasons 1991/1992 to 2005/2006.
Using a stochastic distance frontier approach that allows decomposing total factor productivity change into different sources,
we examine (a) whether Baumol’s cost-disease hypothesis is valid in this sector and (b) if so, whether any negative influence
of the cost-disease effect on productivity can be compensated by efficiency gains. The findings indicate an increase in real
unit labor cost as a result of rising wage rates and thus do support the cost-disease hypothesis. Further, increasing returns
to scale are observed for the majority of the theaters, implying that significant efficiency gains can be realized by the
exploitation of scale economies. However, because of the increasing unit labor cost and an increasing scale inefficiency,
we find an overall decrease in average productivity of about 8% within the sample period. 相似文献

In recent years the economic performance of public non-profit sectors such as cultural services has become an interesting
economic issue. This is due to the high dependence of cultural institutions on public funding on the one hand and the increasing
cost-pressure on public budgets on the other hand. In order to achieve an efficient, cost-minimizing resource allocation public
authorities who decide on the distribution of public budgets need reliable performance indicators. Against this background,
this paper analyzes the efficiency of German public theaters for the seasons 1991/1992–2005/2006. Using a stochastic frontier
analysis approach, we test whether the assumption of cost-minimizing behavior is reliable in this sector. Moreover, several
panel data models that differ in their ability to account for unobserved heterogeneity are applied to evaluate the impact
of unobserved heterogeneity on the efficiency estimates. The results indicate that the cost-minimizing assumption cannot be
maintained. Consequently, an efficiency analysis based on a cost function approach seems inappropriate in the case of German
public theaters. Further, we find a considerable unobserved heterogeneity across the theaters, which causes a significant
variation in the models’ efficiency estimates. This implies that failing to account for unobserved heterogeneity leads to
biased efficiency values. Overall, our results suggest that there is still space for improvement in the employment of resources
in the sector. 相似文献

THE STRUCTURE AND IMPLICATIONS OF CHILDREN'S ATTITUDES TO SCHOOL 总被引：1，自引：0，他引：1

ABSTRACT: The paper reports a study of children's attitudes to school based on a questionnaire survey of 845 pupils in their first year of secondary school in England, together with interviews with a sample of the children. A clearly structured set of attitudes emerged from a factor analysis which showed a distinction between instrumental and affective aspects of attitudes but also dimensions within these, including a sense of teacher commitment and school as a difficult environment. Virtually all children had a strong sense of the importance of doing well at school. However, a substantial minority were not sure that they would stay on after 16. There were few differences between boys and girls or between children from different socio-economic backgrounds but children planning to leave at 16 enjoyed school less and were less sure that it had anything to offer them. There was an almost universal commitment to the value of education but, for a minority, an ambivalence about the experience and relevance of schooling for them. 相似文献

The increasing trend of cross-border globalization and acculturation requires text summarization techniques to work equally well for multiple languages. However, only some of the automated summarization methods can be defined as “language-independent,” i.e., not based on any language-specific knowledge. Such methods can be used for multilingual summarization, defined in Mani (Automatic summarization. Natural language processing. John Benjamins Publishing Company, Amsterdam, 2001) as “processing several languages, with a summary in the same language as input”, but, their performance is usually unsatisfactory due to the exclusion of language-specific knowledge. Moreover, supervised machine learning approaches need training corpora in multiple languages that are usually unavailable for rare languages, and their creation is a very expensive and labor-intensive process. In this article, we describe cross-lingual methods for training an extractive single-document text summarizer called MUSE (MUltilingual Sentence Extractor)—a supervised approach, based on the linear optimization of a rich set of sentence ranking measures using a Genetic Algorithm. We evaluated MUSE’s performance on documents in three different languages: English, Hebrew, and Arabic using several training scenarios. The summarization quality was measured using ROUGE-1 and ROUGE-2 Recall metrics. The results of the extensive comparative analysis showed that the performance of MUSE was better than that of the best known multilingual approach (TextRank) in all three languages. Moreover, our experimental results suggest that using the same sentence ranking model across languages results in a reasonable summarization quality, while saving considerable annotation efforts for the end-user. On the other hand, using parallel corpora generated by machine translation tools may improve the performance of a MUSE model trained on a foreign language. Comparative evaluation of an alternative optimization technique—Multiple Linear Regression—justifies the use of a Genetic Algorithm. 相似文献
