Broadening access to the curriculum through using technology to link home and school: a critical analysis of reforms intended to improve students' educational attainment

This article reports on a UK study identifying innovative practice in the use of ICT to link home and school and its potential for enhancing learning. It is set in the context of recent political tensions and the mismatch between ICT use in the home and traditional educational systems. The theoretical framework draws upon curriculum theories and reviews what is already known about home use of ICT. A survey was administered to schools identified for innovative models of practice in both teaching and learning, and management and administration. From the 115 responses, eight contrasting case-study schools were selected. Three exemplars highlight a shift in practices: a move towards self-directed learning; greater flexibility and autonomy for students; and improved communication between home and school. We argue that technology could support a broader access to the curriculum, but that policy-makers should be aware of the digital divide issues. Young people's home use of technology suggests a rich experience involving exploratory activities, access to knowledge and the opportunity to publish their views. Curriculum reform is essential in order to maximize the potential of technology. It demands a shift away from current curriculum and pedagogy towards critical thinking and knowledge construction.

武术传统技术体系和训练体系的形成

武术在技术上具有技击特点，在文化特征上具有民族特点。其技击特点的保存和发展，与中国哲学的知行合一思想有密切的联系。武术的套路练习和对抗性练习，以及围绕它们而存在的功法构成了武术传统技术体系；而一系列由套路至单势散用，切合实用的训练过程构成了武术传统训练体系。     

老年人生命意义与成功老化

目的：探讨老年人生命意义与成功老化间的关系。方法：采用中文生命意义量问卷、成功老化问卷。通过向福建省内各地区65岁以上老人发放问卷（有专员协助）得到有效问卷228份。结果：①生命意义及其各维度与成功老化呈显著正相关;②男性比女性更易实现成功老化,群居的老年人比独居的老年人实现成功老化的可能性更大。结论：老年人生命意义对成功老化有直接的影响,这一结果对提出老年人生命质量的相关干预策略具有重要的理论依据和现实意义。

Instructional leadership practices in Singapore

This paper presents a review of the literature on principal instructional leadership in Singapore. The authors investigated the dimensions of instructional leadership in the practices of Singapore principals and highlighted the strategies these leaders adopt to enact their instructional roles. Singapore principals were found to play an active role in defining the school vision and promoting the school climate. However, in the areas of curriculum implementation and classroom instruction, the middle management team in the school played more active roles as compared to principals. Five broad conclusions were discussed to provide perspectives on instructional leadership practices in Singapore. This paper also highlighted limitations on current instructional leadership research in Singapore and pointed to areas of future research.     

Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.
