As proposed by social constructive theorists, meaningful learning and individual development were achieved through social interaction. To foster social interaction among students, this study formed an online learning community in which they played multiple roles as writers, editors and commentators. In playing different roles, they read peers' texts, edited peers' errors, evaluated peer editors' corrections and finally reconstructed their own texts. Results of this study showed that the multiple roles they played allowed them to have opportunities to view their own texts from others' perspectives. Based on these perspectives, they were more willing to acquire information from and contribute information to peers. All of this extensive information acquisition and contribution resulted in meaning construction of texts as active students improved their final drafts in both local revision (grammatical correction) and global revision (the style, organisation and development of a text) after receiving and evaluating feedback from peer editors. Their final drafts were very different from those of passive students whose first and final drafts were almost the same despite some grammatical revisions. This study suggests that, rather than relying only on an examination of students' final drafts, there may be benefits in teachers encouraging students to actively participate in social interaction by reading peers' texts, editing peers' errors and evaluating peer editors' corrections during text revisions. 相似文献

Student contribution in asynchronous online discussion: a review of the research and empirical exploration 总被引:1,自引:0,他引:1
The increasingly prevalent use of Internet in schools and homes has resulted in asynchronous online discussion becoming an
increasingly common means to facilitate dialogue between instructors and students, as well as students and students beyond
the boundaries of their physical classrooms. This article is organized into two main sections. In the first section, we review
50 empirical studies in order to identify the factors leading to limited student contribution. Limited student contribution
is defined as students making few or no postings, or students exhibiting surface-level thinking or low-level knowledge construction
in online discussions. We then identify the various empirically based guidelines to address the factors. In the second section,
we discuss three potential guideline dilemmas that educators may encounter: (a) use of grades, (b) use of number of posting
guideline, and (c) instructor-facilitation. These are guidelines where previous empirical research shows mixed results when
they are implemented. Acknowledging the dilemmas is essential for educators and researchers to make informed decisions about
the discussion guidelines they are considering implementing. Finally, we report two exploratory case studies on student-facilitation
that we conducted. Using students as facilitators may be an alternative solution to educators who wish to avoid the instructor-facilitation
guideline dilemma. 相似文献

Though lattice-based information representation has the advantage of providing efficient visual interface over textual display, the complexity of a lattice may grow rapidly with the size of the database. In this paper we formally draw the analogy between Vector Space Model and Concept Lattice, from which we introduce the notion of Term-Document Lattice as a model for information retrieval. We then propose to use the idea of quotient lattice to reduce the complexity of a Term-Document Lattice. The equivalence relation required to construct the quotient lattice is obtained by performing a Singular Value Decomposition on the original term-document matrix. 相似文献

The purpose of this study was to examine friendship developments of 153 Vietnamese immigrant adolescents who resided in an East Coast metropolitan area of the United States. We examined the influences of school diversity and acculturation on the quantity and quality of cross-and same-race friendships. Surprisingly, students who came from schools that are more diverse reported fewer cross-race friendships and lower levels of social support from their cross-race friends. American acculturation predicted greater levels of social support from cross-race friends. For same-race friendships, students who went to schools with higher percentage of Asian students reported more same-race friendships; however, percentage of Asian students was not a significant predictor of social support from same-race friends. Students who reported greater levels of Vietnamese acculturation reported greater levels of social support from their same-race friends. This study has implications for understanding the impact of school diversity and acculturation on friendship development of Vietnamese immigrants. Also, suggestions on how to better conceptualize and measure diversity are discussed. 相似文献

The Social Stratification of Cultural Consumption: Some Policy Implications of a Research Project 总被引:1,自引:0,他引:1
The paper briefly describes a recently completed research project on the social stratification of cultural consumption, presents some major findings from this project, and considers their implications for public policy in relation to the arts. A central theme is the inadequacy of the ‘homology’ argument, claiming that social hierarchies and cultural hierarchies map closely onto each other. This argument is shown to be empirically unsound and to underestimate the complexity of the relationship between social stratification and cultural consumption, as this is determined by the combined effects of income, education and social status. One question that then arises is what policy response, if any, is required by the fact that many individuals do not participate extensively in the arts even though they have the economic and cultural resources required to do so (self-exclusion rather than social exclusion). And a second is that of how far, in attempts at increasing participation, status-linked motivations might be exploited. 相似文献

This study aimed to understand the environmental knowledge (EK) of the residents of Hong Kong. A territory-wide survey was administered to investigate the subjective and objective EK of the respondents as well as their means of receiving information about the environment. The results indicated that Hong Kong’s residents have a comparatively low level of EK, with a mean environmental knowledge score of 3.35 out of 8. The youngster (15–24?years old), students, and employed individuals reported more extensive EK than the older and unemployed respondents, thus suggesting that the younger generation and employed individuals have increased opportunities to receive EK through various channels. A weak positive correlation was identified between subjective and objective EK, thus implying that the residents of Hong Kong could not accurately evaluate their own level of EK. The results indicate that traditional media plays a significant role in disseminating EK. Digital media, such as websites and digital social networks, were also determined to be influencing factors in disseminating environmental messages to the younger generation. 相似文献

As digital technologies form an inextricable part of young people's everyday lives, some commentators claim that the current generation of learners think and learn differently from their predecessors. This study investigated the validity of this claim by surveying 799 undergraduate and 81 postgraduate students at a large research‐intensive university in New Zealand to document their use of digital technologies on university and social activities and comparing three age groups of students (under 20, 20–30 and over 30) to see whether there were any differences in their learning characteristics. The findings of the study showed that while students spent a large amount of time on digital technologies, the range of digital technologies they used was rather limited. There were also no practical generational differences in the technology use pattern and learning characteristics found in this study. The results of this study suggest that generation is not a determining factor in students' use of digital technologies for learning nor has generation had a radical impact on learning characteristics of higher education students. 相似文献

Excessive foot pronation is a risk factor of running injuries and motion control footwear is designed to control foot pronation. With the movement transfer between foot pronation and tibial rotation, motion control footwear may not only be confined to controlling foot pronation. In view of the controversies in the literature on effectiveness of motion control footwear, this paper reviewed the efficacy of motion control footwear functions as reported in the literature. Eligible studies were identified from seven electronic databases. Two independent authors extracted the data and assessed the methodological qualities using the Jadad Scale. A total of 14 quasi randomised controlled trials were included. Even though the included studies were rated as "low quality" according to the Jadad Scale, the data were pooled and analysed. Results revealed that motion control footwear was effective in reducing the amount of foot pronation and the peak vertical impact during landing. There is no evidence that suggests motion control footwear for controlling kinematics of the proximal segments. 相似文献
