This paper describes an approach to evaluating the usefulness of an Animated Program Tracer (APT) in communicating run-time information to novice Prolo programmers. The method used in the evaluation consists of a set of programs which have been specially designed to elicit how novices think Prolog programs are executed, and thus to reveal how accurate their model of program execution is. Two experiments are reported. The first determines the misconceptions that novices hold about the runtime actions of the Prolog interpreter, and produces six different categories of misconception. The second experiment investigates the ability of APT to communicate run-time information to novice Prolog programmers. A scoring technique was used to interpret subjects' answers, and shows that there was a significant improvement in the scores of the group who saw programs traced by APT when compared with a control group who saw no trace. 相似文献
The aim of this explorative study was to develop and test a pedagogy aimed at promoting students’ ability to perform historical contextualization. Teaching historical contextualization was conceptualized in terms of four pedagogical design principles: (1) making students aware of the consequences of a present-oriented perspective when examining the past, (2) enhancing the reconstruction of a historical context, (3) enhancing the use of the historical context to explain historical phenomena and (4) enhancing historical empathy. The effectiveness of these principles was explored in a lesson unit focusing on the seventeenth and eighteenth centuries. In a quasi-experimental pre-test–post-test design with experimental and control conditions, the effects of the pedagogy on 15- and 16-year-old students’ ability to perform historical contextualization were examined (n = 131). The results indicated that students in the experimental condition significantly improved their ability to perform historical contextualization compared to students in the control condition. These findings could be used to help teachers and other educational professionals design and implement historical contextualization tasks and instructions. 相似文献
The main purpose of this study is to unravel the impact of the Big Five personality factors on academic performance. We propose a theoretical model with conditional indirect effects of the Big Five personality factors on academic performance through their impact upon academic motivation. To clarify the mixed results of previous studies concerning the impact of neuroticism, we suggest a moderating role of self-efficacy. Hierarchical, moderated mediation and mediated moderation regression analyses were performed on longitudinal data collected from 375 students of a University college in Belgium. The findings revealed a positive indirect effect of neuroticism on academic performance at higher levels of self-efficacy, complemented by a positive direct effect of neuroticism at lower levels of self-efficacy. Finally, this study showed that conscientiousness positively affected academic performance indirectly through academic motivation, but also that it is a condition for the indirect impact of extraversion, neuroticism, and conscientiousness. 相似文献
Jonathan Boston provides an insightful analysis of the emergence and persistence of child poverty in New Zealand (Boston, 2014, Educational Philosophy and Theory). His remarks on why child poverty matters are brief but, as he reports, “[t]here is a large and robust body of research on the harmful consequences of child poverty” (Boston 2014, pp. 10–11). One cost he does not explicitly mention is the increased risk of maltreatment faced by children living in poverty. Given the clear correlation between risk of abuse and poverty, Boston’s recommendations might be expected to go some way to addressing New Zealand’s appalling child maltreatment statistics. However, Boston himself identifies both fiscal and political barriers to the implementation of his proposed strategy. “Fundamentally”, he observes, “without adequate multi-party agreement, it will be hard to reduce child poverty on a durable basis” and “[c]urrently, such agreement is lacking” (Boston, 2014, p. 21). Even if we accept Boston’s strategies for child-poverty reduction, then, it is prudent to consider other responses to the consequences of child poverty. Significant and controversial aspects of New Zealand’s 2013 White Paper for Vulnerable Children can be read in this light, and one of them – the proposal to use predictive risk modeling (PRM) to identify children at risk of maltreatment – is the focus of this commentary. 相似文献
Recent research suggests that Muslim boys have become the ‘New Folk Devils’ of British education, who are characterised by resistance to formal education, especially at secondary level, and under-achievement. Since the 1990s, British Muslim boys would appear to have become increasingly alienated from compulsory schooling, especially in the humanities subjects which lack obvious instrumental value.
This mixed-methods study of the performance of 295 secondary school British Muslim boys in their compulsory school history provides evidence which interrupts this narrative of the academic under-achievement and educational dis-engagement of Muslim boys, especially in the humanities subjects. When viewed through the prism of a laminated, non-reductive model of educational success, this indicative sample of British Muslim boys could be considered to have had significant success at a traditional humanities subject such as history intellectually, spiritually, emotionally, instrumentally and civically.
This paper therefore proposes that history can provide a vital meaning-making tool to generate the success of Muslim boys in a variety of significant dimensions both in and out of school. It suggests how history can be more fully and effectively harnessed by teachers, parents and policy-planners to encourage internal integration and external social engagement in British Muslim pupils. 相似文献
This paper describes the user-focused approach to information skills at MMU Library. It covers the following cycle: identifying training needs at three levels (organisation, group and individual); developing a training strategy and materials; marketing information skills within MMU. Specifically, it describes how we went about discovering what our users wanted, creating and delivering what they needed, and how we ‘sold’ it back to them. 相似文献
The diffusion of international television programs has been an important area of international communication research. In this article, we use theoretical constructs from country-of-origin and cultural proximity literatures and develop a model to explain audience's attitudes toward and willingness to watch imported television programs from China. Our study used a questionnaire survey method to collect data from 553 respondents in Taiwan. We examined television programs imported from China, a country that has tried to invade Taiwan to destroy its democracy in the past decades. Regression analyses found that, whereas cultural proximity was an important predictor, animosity turned out to be a more powerful predictor of Taiwanese audience's attitudes toward television programs from China. The results also demonstrated that if the Taiwanese audience perceived China as holding less animosity and more cultural proximity, they had more positive attitudes and were more willing to watch television programs imported from China. 相似文献
This article explores the possibility of journalists acting as custodians of critical engagement, drawing on Rancière's conception of dissensus as organized disagreement over the conditions of understanding. It begins by assessing the status that worthiness and naiveté have as negative symbolic capital in the journalistic field, before asking whether journalists' ambivalent detachment from the objects of their inquiry hinders their ability to engage critically with experts in other fields. It argues that journalism's role in marshaling dissensus amounts to making clear the limits and absences of intelligibility in journalism and other fields, in distinction to disseminating knowledge as such. 相似文献
