This paper describes an online learning resource for rheumatology that was designed for a wide constituency of users including primarily undergraduate medical students and health professionals. Although the online resources afford an informal learning environment, the site was pedagogically designed to comply with the general recommendations of the Standing Committee on Training and Education of EULAR (European League Against Rheumatism) for a rheumatology core curriculum. Any Internet user may freely browse the site content with optional registration providing access to adaptive features that personalize the user's view, for example, providing a reading history and targeted support based on scores from completed case studies. The site has now been available since early 2003, and an online survey of site registrants indicates that well structured pedagogical materials that reflect a learners' dominant ‘community of practice’ appear to be a successful aid to informal learning.  相似文献

This study investigated the relationships of students’ incremental beliefs of math ability to their achievement emotions, classroom engagement and math achievement. A sample of 273 secondary students in Singapore were administered measures of incremental beliefs of math ability, math enjoyment, pride, boredom and anxiety, as well as math classroom attention and disruption. In addition, students’ end-of-year math achievement scores were collected from school records. The hypothesised mediation model was supported in structural equation modelling analysis. Incremental beliefs of math ability were associated positively with math enjoyment and pride, and negatively with math boredom and anxiety. Achievement emotions fully mediated the relationships of incremental beliefs of math ability to classroom engagement and math achievement. Incremental beliefs of math ability were associated positively with classroom attention through math enjoyment and pride, negatively with classroom disruption through math anxiety and positively with math achievement through the two outcome-related emotions, math pride and anxiety. The findings and implications are discussed in the academic context of Singapore.  相似文献

The fundamental concepts of ethics: value, obligation and responsibility are what many of us use in our everyday decision‐making on issues that affect our lives. Students in the coursework unit ‘Science and technology in contemporary society’ learn about these concepts in relation to science and technological research and development. The learning takes place in small teams within an online learning environment. This research study reports on a case study that investigated the nature of the collaboration by virtual team members undertaking semi‐structured online tasks to develop an understanding of the topic on ethics in the coursework unit. Students’ perceptions of the usefulness of this type of learning, the types of collaboration that took place between virtual team members and an analysis of the quality of the completed tasks resulting from the virtual teamwork are presented in this paper. Factors affecting the success of the learning experience are also discussed.  相似文献

Background : The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries.

Purpose : This study explored the relationship between positive affect towards science and mathematics and achievement in science and mathematics among Malaysian and Singaporean Grade 8 students.

Sample : In total, 4466 Malaysia students and 4599 Singaporean students from Grade 8 who participated in TIMSS 2007 were involved in this study.

Design and method : Students’ achievement scores on eight items in the survey instrument that were reported in TIMSS 2007 were used as the dependent variable in the analysis. Students’ scores on four items in the TIMSS 2007 survey instrument pertaining to students’ affect towards science and mathematics together with students’ gender, language spoken at home and parental education were used as the independent variables.

Results : Positive affect towards science and mathematics indicated statistically significant predictive effects on achievement in the two subjects for both Malaysian and Singaporean Grade 8 students. There were statistically significant predictive effects on mathematics achievement for the students’ gender, language spoken at home and parental education for both Malaysian and Singaporean students, with R 2 = 0.18 and 0.21, respectively. However, only parental education showed statistically significant predictive effects on science achievement for both countries. For Singapore, language spoken at home also demonstrated statistically significant predictive effects on science achievement, whereas gender did not. For Malaysia, neither gender nor language spoken at home had statistically significant predictive effects on science achievement.

Conclusions : It is important for educators to consider implementing self-concept enhancement intervention programmes by incorporating ‘affect’ components of academic self-concept in order to develop students’ talents and promote academic excellence in science and mathematics.  相似文献

In general, this essay explores the theoretical and practical political problems associated with being an Olympic anthropologist. In particular, it examines the practical attitude that an anthropological relativist should adopt toward universal humanism in pluricultural contexts. As such, this essay serves as a critique not only of the dominant Olympic ideology itself but also of the Olympic leaders who embrace the universalist claims of Olympism and the scientists of sport who reinforce the European versions of universal humanism by which those same Olympic officials typically comprehend the world.  相似文献

Animation has an inherent advantage over static graphics when presenting dynamic content because it provides a more accurate and realistic depiction. Simultaneously, animation has an inherent disadvantage because most animated information is perceptually transient. In this quasi-experimental study, cognitive load theory was used to investigate the extent to which animation’s transience could be ameliorated with the incorporation of a pause/play feature or a tracing feature that lets previous information remain visually available on screen instead of disappearing after a brief display. Continuous animation, animation with pause/play and their equivalent static graphics, each designed with either a trace or no trace, were used to instruct 228 post-secondary technical education students on how an electrical circuit works. All formats were accompanied with the same on-screen text. The pattern of results, especially the interactions, indicated that animation with a pause/play format obtained the highest efficiency in the no tracing condition, while the continuous animation format obtained the highest efficiency in the tracing condition. These results suggest that by restructuring the dynamic information, the negative instructional consequences of the transient nature of animation can be counteracted to make it more efficient for learning than static graphics.  相似文献

Solving ill-structured problems is regarded as an important learning outcome in education as it allows learners to apply theories learnt into real practice. An asynchronous online discussion, with extended time for reflection, is an appropriate learning environment to engage learners in solving ill-structured problems. However, scaffolds may be needed to support learners in the online discussions. This study explores the effect of online scaffolds in supporting a group of graduate students' ill-structured problem-solving processes in asynchronous online discussions. The results of this study showed that the use of the online scaffolds did not lead to a significant difference in the number of ill-structured problem-solving processes. Further analysis revealed that wrong selection of message labels and under-usage of sentence openers affected the results of this study. Improvements for online scaffolds include having more precise message labels and sentence openers based on Socratic questioning approach.  相似文献

This article examines the determinants of eco-friendly electronic good consumption among students at a large Australian university who have been exposed to a marketing campaign, Mobile Muster. Empirical research generally shows younger consumers to be less concerned about the environment. Similar studies demonstrate that peer pressure has a large role to play. Accordingly, using the theories of reasoned action and planned behavior, this study examines subjective norms, attitudes, perceived control, environmental concern, altruism, risk aversion, price consciousness, involvement, branding, environmental knowledge, and their relationship with purchase intentions. It is the first study to examine these effects on the purchase of eco-friendly phones, a product of high personal relevance to these consumers. Mediation effects were also assessed. Results showed that subjective norms (friends/experts) can increase intentions and mediate the relationship between information and intentions. Involvement emerged as a significant influencer on intentions, presenting new findings for the literature. Moreover, higher levels of objective knowledge increased intentions. This supported the significant role of the Mobile Muster scheme in dispersing knowledge. These findings are of practical value to educators, allowing them to determine factors that influence consumer knowledge and norms with the aim of enabling students to form more ecological relevant purchase intentions.  相似文献
