This study investigated the development of visual chunking skills in the processing of Chinese characters among Hong Kong
pupils. One-hundred-seventy-nine primary school students from first, second and fourth grades were administered a character
copying task. Children as young as 6 years of age were aware of character units and were able to apply visual chunking strategies
when processing characters. Children in higher grades performed better than those in lower grades on every character type,
and the types of errors they made revealed that their chunking level was higher than that of younger children. Differences
between ability groups emerged in second grade and vanished in fourth grade, suggesting that children with a lower reading
ability are slower to develop advanced chunking skills. 相似文献

教育制度:概念的厘定 总被引：6，自引：0，他引：6
李江源 《河北师范大学学报(教育科学版)》2003,5(1):20-31
虽然要对教育制度下一个准确的、为各方所认可的定义十分困难 ,但我们认为 ,一个完整准确的教育制度定义 ,至少应当包含以下几个基本的方面 :即 ,教育制度是教育活动的规则 ;教育制度是“社会的”制度 ;教育制度具有程度不同的权威性或强制性。在此基础上 ,我们可以将“教育制度”概念大致地界定为 :教育制度是用以调整个体行动者之间以及特定教育组织内部行动者之间关系的强制性或权威性的行为规则体系 相似文献

This study explored the influence of residency status (outsider) and prior cross-cultural experiences on how the neighborhoods
of students are perceived by future teachers. The study participants consisted of 18 graduate teacher education mentors and
their 18 high school mentees. The data sources included 820 black and white photographs and 82 photo captions generated by
the study participants, mentee/mentor group discussions, and the graduate students’ weekly reflective journals, bi-weekly
facilitated discussions and peer debriefings. The study found that subconscious realities based on prior cross-cultural experiences
(or the lack thereof) are more significant factors than residency status when making value judgment about the neighborhoods
of “others.”

This paper explores trade-offs between knowledge exploitation and exploration activities. The study of exploitation and exploration activities is not new; however, rarely has past research perceived exploitation and exploration activities as two edges of one continuum. Furthermore, little evidence has been reported as to the actual trade-offs that firms face when launching either exploration or exploitation activities. This paper sets about filling this gap by addressing the following question: To what extent does an investment in one exploitation activity hinder the development of an exploration activity within the firm? A new process innovation targeting the exploitation of the firm's internal capabilities through an extensive component reuse and reconfiguration program is studied and the implications for inter-related exploration activities, such as the development of engineers' expertise is examined. To reveal the trade-offs between exploration and exploitation activities, both changes within and between these exploitation and exploration activities, over time, are studied. Based on data drawn from an in-depth study of several product development project teams in one high-tech company, we conclude that by investing in exploitation activities, a firm may limit some specific exploration activities. 相似文献

This paper analyzes ethical aspects of the new paradigm of Ambient Intelligence, which is a combination of Ubiquitous Computing
and Intelligent User Interfaces (IUI’s). After an introduction to the approach, two key ethical dimensions will be analyzed:
freedom and privacy. It is argued that Ambient Intelligence, though often designed to enhance freedom and control, has the
potential to limit freedom and autonomy as well. Ambient Intelligence also harbors great privacy risks, and these are explored
as well. 相似文献

Culture is widely acknowledged to be a critical success factor in knowledge management (KM). This paper presents the case of KM implementation at MKS, an IT consulting firm based in India. Although the KM initiative at MKS had many of the hallmarks associated with successful KM projects, the initiative failed to get off the ground due to the absence of a ‘knowledge culture’ within the organisation. Subsequent interviews with MKS staff uncovered a range of cultural themes that appeared to impede the institutionalisation of KM at MKS. These cultural themes included:

- internal competitiveness among MKS staff resulting in ‘knowledge hoarding’,
- a lack of personal reward and incentive to engage in knowledge sharing,
- concerns over job security and the ‘devaluation’ of employees,
- stigma associated with the reliance on someone else's ideas,
- preference for a face-to-face mode of knowledge sharing over a tool-supported approach and
- doubts over the quality of knowledge shared by more junior staff.

The objective of this paper is to investigate the role of knowledge management (KM) in networks participated by small firms. To achieve this objective, the literature on KM in small firms has been reviewed. A research question has been defined and addressed through a questionnaire survey conducted in a small firms network. The findings indicate that the surveyed companies perceive the strategic value of KM and adopt several systems even if its adoption is constrained by a number of barriers. The results suggest that firms investigated need to adopt advanced KM systems to manage knowledge more effectively at network level. The evidences also indicate that the surveyed firms are willing to adopt a platform supporting the sharing and exchange of knowledge in the network with a positive impact on innovation processes and the exploitation of market opportunities. The paper outlines some managerial implications as well as avenues for further research. 相似文献
