AbstractThe purpose of this study was to examine student perceptions of the learning environment in their program major and general education classrooms. The participants were 870 undergraduate students majoring in engineering, fine arts, education, economics and nursing programs at a university in Thailand. We found significant differences in the perceptions of the classroom learning environment across various disciplines. Engineering and economics students perceived the learning environment in general education classrooms as more cooperative than the learning environment in program major classrooms. Fine arts and nursing students perceived greater involvement among students in the program major classrooms than in the general education classrooms. Our findings contribute to the body of research on inter-disciplinary differences in classroom learning environments in universities and the ways in which these differences may impact student learning outcomes. 相似文献

In the whole world, the internet is exercised by millions of people every day for information retrieval. Even for a small to smaller task like fixing a fan, to cook food or even to iron clothes persons opt to search the web. To fulfill the information needs of people, there are billions of web pages, each having a different degree of relevance to the topic of interest (TOI), scattered throughout the web but this huge size makes manual information retrieval impossible. The page ranking algorithm is an integral part of search engines as it arranges web pages associated with a queried TOI in order of their relevance level. It, therefore, plays an important role in regulating the search quality and user experience for information retrieval. PageRank, HITS, and SALSA are well-known page ranking algorithm based on link structure analysis of a seed set, but ranking given by them has not yet been efficient. In this paper, we propose a variant of SALSA to give sNorm(p) for the efficient ranking of web pages. Our approach relies on a p-Norm from Vector Norm family in a novel way for the ranking of web pages as Vector Norms can reduce the impact of low authority weight in hub weight calculation in an efficient way. Our study, then compares the rankings given by PageRank, HITS, SALSA, and sNorm(p) to the same pages in the same query. The effectiveness of the proposed approach over state of the art methods has been shown using performance measurement technique, Mean Reciprocal Rank (MRR), Precision, Mean Average Precision (MAP), Discounted Cumulative Gain (DCG) and Normalized DCG (NDCG). The experimentation is performed on a dataset acquired after pre-processing of the results collected from initial few pages retrieved for a query by the Google search engine. Based on the type and amount of in-hand domain expertise 30 queries are designed. The extensive evaluation and result analysis are performed using MRR, [email protected], MAP, DCG, and NDCG as the performance measuring statistical metrics. Furthermore, results are statistically verified using a significance test. Findings show that our approach outperforms state of the art methods by attaining 0.8666 as MRR value, 0.7957 as MAP value. Thus contributing to the improvement in the ranking of web pages more efficiently as compared to its counterparts. 相似文献

Medical doctor and engineer are highly esteemed STEM professions. This study investigates academic and motivational characteristics of a sample of high school students in Thailand who aspire to become medical doctors or engineers. We used logistic regression to compare maths performance, gender typicality, gender contentedness, and maths and physics self-concepts among students with aspirations for these two professions. We found that high levels of felt gender contentedness in men had positive association with aspirations for engineering irrespective of the levels of maths or physics self-concept. We found that high levels of felt gender contentedness combined with high levels of maths or physics self-concept in women had positive associations with aspirations to become a medical doctor. These findings are evidence that student views of self are associated with uneven gendered patterns in career aspirations and have implications for the potential for future participation. 相似文献

What is the nature of the force or mechanism that moves massive continents thousands of miles across? What causes violent earthquakes to displace huge landmasses abruptly? How could great mountain ranges like Himalayas and Alps rise to such incredible heights? What makes earth's interior so restless? Answers to some of these questions may lie in understanding the Earth's interior itself. 相似文献

This study examined the level of instructional use of Internet among science teachers involved with an in-service professional development project. An instrument on Level of Use of innovation was modified for the study. A criterion sample of teachers to be interviewed via telephone was randomly selected from a pool of 347 K–12 teachers. Somers' d and contingency coefficients were determined to see whether any relationship exists between a teacher's Level of Use and the following categories: (a) amount of experience with the Internet; (b) availability of resources support and access to the Internet in classroom and at home; (c) number of teacher and student users at school, (d) gender; and (e) type of school. Results of step-wise multiple regression indicate that classroom access, instructional experience of using Internet with students, availability of resource support and number of teacher users at school are the best predictors of teacher's Level of Use. Chi square test for comparisons between groups of completers and noncompleters of On-Line West Virginia K–12 RuralNet courses also revealed that a lack of classroom access to Internet and lack of resource/technical support at school contributed significantly to lower level of use among noncompleters. 相似文献

This investigation considered how undergraduate students with different achievement goal orientation profiles view plagiarism. Thai student volunteers (N = 867) completed an achievement goal survey [Niemivirta, M. (1998). Individual differences in motivational and cognitive factors affecting self-regulated learning — A pattern-oriented approach. In P. Nenninger, R. S. Jäger, A. Frey, & M. Woznitza (Eds.), Advances in motivation (pp. 23–42). Landau, DE: Verlad Empirische Pädagogik] and a “Dimensions of Plagiarism” survey [Koul, R. (2007). Dimensions of Plagiarism. Downloaded April 8, 2008 from http://dimensions-of-plagiarism.wikispaces.com/]. Mixed analysis of variance of attitudes towards plagiarism with goal orientation and gender showed several significant findings: high performance oriented students were substantially stricter than low performance orientated students in evaluating all Dimensions of Plagiarism. Low mastery oriented students were stricter regarding the “motive” dimension of plagiarism while high mastery oriented students were stricter regarding the “source” dimension of plagiarism. Significant differences between females and males were observed across the six factors of the Dimensions of Plagiarism survey. These results are interpreted within the framework of social comparison theory in respect to competitive learning environments. 相似文献

This paper traces attempts by two ‘brand-name’ research universities to transnationalise: the US-based Johns Hopkins University,
and the University of New South Wales from Australia. Both endeavours were located in, and supported by, Singapore, a city–state
with knowledge economy aspirations. The paper explores the globalisation of the research university, and offers insights into
the regimes of value that are being assembled in, and through knowledge economies. Both institutions examined in this study
failed in their attempts ostensibly because of a lack of fit in goals and commitment. The paper also highlights the ethical
issues that frame the globalizing rationalities of research-intensive universities and developmental states seeking competitive
advantage in a neoliberalising environment. 相似文献

To maintain their global positioning, some of the world's most prominent institutions are pursuing strategic transnational alliances. In this paper I examine one such transnational alliance – that between the Massachusetts Institute of Technology and the government of Singapore. Using governmentality as a framework of analysis, the paper locates the Singapore‐MIT Alliance within the broader policy architecture that underpins Singapore's knowledge economy aspirations. The Alliance demonstrates some of the practical complexities involved in ‘leap‐frogging’ into the ‘value‐added’ realms of knowledge and service‐related production. It highlights the resistances, tensions and contradictions arising from leveraging off foreign expertise to build an education hub. The paper concludes with a discussion of the changing regimes of value arising from aspiring knowledge economies. 相似文献

This article uses Foucault’s concept of the care of the self to interrogate the accounts of ethical agency provided by professionals involved in the settlement of refugees, in a global and national context marked by fear of the stranger and the embrace of neoliberal political rationalities. An argument is made to ‘free the professional self’ by refusing an individualised, psychologised and dehistoricised approach in working with refugees and asylum seekers. In its place, a threefold ‘ethics of engagement’ for ‘international citizenship’ is proposed as a way forward to further professionalism and civic action. By understanding the refugee problem as an ‘integral part of North-South relations’ rather than as a ‘Third World’ problem, new possibilities are opened for an ethics of civility and an ethics of care. 相似文献
