在华人社会,道德教育一直以来都是教育最基本的组成部分,因为培养有道德的人是教育的首要任务。道德教育的实施,其实是培植那些反映道德标准的价值观。然而,信息时代的出现及充斥在互联网上的大量信息,已改变了教育的方式,并向传统的道德教育发出挑战。在这一背景下,我们建议中国的教育工作者应寻求实践道德教育的新途径,以迎接网络世界的出现。崇高空洞的道德标准应让位给简洁易懂的观念,比如“尊重”。我们应该积极的去探索“网络世界”中的信息和观念,而不是一味的避免。有启发性和适切的道德教育应建基于儿童和青少年的发展需要和真正兴趣之上。华人社会的德育工作者,包括学校教师,家长,非正式教育的组织者,都应共同努力去了解虚拟的网络世界,并设计出可行的方法来适应新形势下的教育需要。 相似文献

Dyslexia is a developmental disability affecting the acquisition of reading and writing skills, and its developmental nature makes longitudinal research of great importance. This study therefore investigated the cognitive-linguistic profiles of the typical-functioning dyslexics and high-functioning dyslexics with longitudinal cohorts of Chinese-speaking adolescents diagnosed with childhood dyslexia. These two dyslexic groups of fifty students (with 25 typical-functioning dyslexics) were assessed in Grade 2 (Time 1) and in Grade 8 (Time 2), whereas 25 typically developing controls were assessed at Time 2. Students were administered measures of phonological awareness, morphological skills, visual-orthographic knowledge, rapid naming, verbal working memory, and literacy skills. Results showed that, at Time 2, both dyslexic groups performed less well than the control group on most of the measures. Deficits in rapid naming were particularly salient in both dyslexic groups. Comparing the two dyslexic groups, the typical-functioning dyslexics had more multiple deficits than the high-functioning dyslexics. Findings highlight the importance of rapid naming deficits as potential universal causes of dyslexia and the utility of targeting visual-orthographic knowledge and morphological skills in supporting the development of dyslexic adolescents. 相似文献

Identification of individual learning style is important when developing adaptive educational hypermedia systems. Current systems ask learners to complete questionnaires to identify their learning styles, which might not be appropriate in some contexts. The goal of this research is to identify the learner's learning style by simply observing his/her browsing behaviour without asking the learner to answer any questions or filling out any form. It is implemented through a multi‐layer feed forward neural network (MLFF). Browsing behaviour, in this research, includes three factors, the use of embedded support devices (ESDs), the selection of link types, and the navigation between visited/unvisited nodes. The experiment results showed the proposed model performed well in identifying learning styles. Link type is the dominant factor and Time shift may not be a major factor in the identification of learning styles. Because of the fast execution property of neural networks and identification of learning styles online, it is possible to incorporate learning styles into online adaptive educational web‐based systems. 相似文献

ABSTRACTA national survey of academic librarians was conducted to examine relationships among reference service staffing changes, reference service innovations, adoption of reference technology, library type and size, and service quality. Analysis of the 606 response sets reveals trends toward reduced use of librarians and increased use of student staff at in-person service points, widespread increases in appointment-based and self-service reference, intensive efforts to reduce demand for reference by improving library instruction, and general improvements in reference service quality. Factors strongly associated with decreases or increases in quality are discussed in detail and implications for reference managers are provided. 相似文献

This article examines the use of pornographic media by Taiwanese high school students, and explores the effects of exposure to such on their attitudes and behaviour in terms of sexual permissiveness. The results of this research indicate that more than 90 per cent of the students interviewed had at least some exposure to a variety of pornography, with males reporting significantly higher exposure frequencies than females. The results also show that exposure to pornographic media has significant effects on high school students’ sexual permissiveness and nonexclusive sexual attitudes and behaviour. 相似文献

The focus of this work is the wood polychrome model of the church of S. Maria della Consolazione in Todi, an artefact whose author and historical events are not completely known except a general reference to the construction period of the church (1508–1607 AD). In this study, original and additional materials were examined in order to provide a deeper understanding of the painting and assembly techniques, and a greater awareness of how well preserved the object is, as well as an analysis of previous preservation and conservation interventions. The samples from the painted surfaces were examined by means of micro-Raman spectroscopy, fourier transform infrared (FTIR) spectrometry and internal microstratigraphic analysis. Thin sections of the wood samples were examined under an optical transmission light microscope in order to identify the botanical species. The results shown in this paper suggest the possibility that the original painted layers are made of calcium carbonate white, red ochre and indigo and they were applied by protein binder without any ground layer. Some non-original pigments were found on the model surface like Prussian blue and chrome yellow. Concerning wood components, poplar was characterized both in the original and non-original parts of the model whereas pine species were detected only in the restoration elements. 相似文献

Mining direct antagonistic communities in signed social networks 总被引:1,自引:1,他引:0

Social networks provide a wealth of data to study relationship dynamics among people. Most social networks such as Epinions and Facebook allow users to declare trusts or friendships with other users. Some of them also allow users to declare distrusts or negative relationships. When both positive and negative links co-exist in a network, some interesting community structures can be studied. In this work, we mine Direct Antagonistic Communities (DACs) within such signed networks. Each DAC consists of two sub-communities with positive relationships among members of each sub-community, and negative relationships among members of the other sub-community. Identifying direct antagonistic communities is an important step to understand the nature of the formation, dissolution, and evolution of such communities. Knowledge about antagonistic communities allows us to better understand and explain behaviors of users in the communities. 相似文献

AbstractElite-standard rowers tend to use a fast-start strategy followed by an inverted parabolic-shaped speed profile in 2000-m races. This strategy is probably the best to manage energy resources during the race and maximise performance. This study investigated the use of virtual reality (VR) with novice rowers as a means to learn about energy management. Participants from an avatar group (n = 7) were instructed to track a virtual boat on a screen, whose speed was set individually to follow the appropriate to-be-learned speed profile. A control group (n = 8) followed an indoor training programme. In spite of similar physiological characteristics in the groups, the avatar group learned and maintained the required profile, resulting in an improved performance (i.e. a decrease in race duration), whereas the control group did not. These results suggest that VR is a means to learn an energy-related skill and improve performance. 相似文献

This study aimed at identifying important skills for reading comprehension in Chinese dyslexic children and their typically
developing counterparts matched on age (CA controls) or reading level (RL controls). The children were assessed on Chinese
reading comprehension, cognitive, and reading-related skills. Results showed that the dyslexic children performed significantly
less well than the CA controls but similarly to RL controls in most measures. Results of multiple regression analyses showed
that word-level reading-related skills like oral vocabulary and word semantics were found to be strong predictors of reading
comprehension among typically developing junior graders and dyslexic readers of senior grades, whereas morphosyntax, a text-level
skill, was most predictive for typically developing senior graders. It was concluded that discourse and morphosyntax skills
are particularly important for reading comprehension in the non-inflectional and topic-prominent Chinese system. 相似文献

ABSTRACTTheoretically, organisational culture, instructor training, and learning space design influence how faculty teach STEM courses. Previous studies have used classroom observation protocols to characterise the range of teaching practices in mostly teacher-centered, traditional STEM classrooms. In this study, we examined the classroom behaviour of 13 STEM faculty teaching biology courses in a reformed undergraduate STEM learning environment. Our findings indicate that instructors teaching in this reformed environment guided student learning (58.4?±?1.9%) almost three times more than they presented information (20.0?±?2.2%). Students worked individually or in groups and talked to the whole class (57.1?±?1.8%) 1.5 times more than they received information (35.5?±?1.9%). We found significant positive correlation between ‘instructor presenting’ and ‘students receiving’ information (r?=?0.743, p?=?1.4?×?10?4) and ‘instructor guiding’ and ‘student working and talking’ in class (r?=?0.605, p?=?7.2?×?10?5), suggesting that instructors can change their own classroom behaviours and expect concurrent change in their students’ behaviours. Finally, sequencing teaching practices in high active-engagement classrooms showed instructors move and guide student group work and lead whole class discussions before lecturing to students, which could lead to deeper learning of conceptual knowledge. We discuss insights from these findings that have implications for acculturating evidence-based teaching practices in STEM departments. 相似文献
