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.  相似文献   

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow     

Jeonghun Nam  Justin Kok Soon Tan  Bee Luan Khoo  Bumseok Namgung  Hwa Liang Leo  Chwee Teck Lim  Sangho Kim 《Biomicrofluidics》2015,9(6)

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.  相似文献   

Cultural Trends of Audience Online Interaction with Vocal Talent Shows: A Comparative Study between China and the US     

Yafei Zhang  Andrea M. Weare  Heungseok Koh  Li Chen 《Journal of Intercultural Communication Research》2016,45(3):196-213

This study examined cultural reflections online of audience comments on social network sites regarding vocal talent shows in China and the United States. The study applied dimensions of cross culture to investigate audience comments on the official social networking sites of The Voice of China and The Voice. Findings reflect Hofstede’s dimensions as applied to social media and illustrate how individuals alter their “local” cultural norms in the new media environment. The study specifically enhances the exploration of cultural manifestations in cyberspace, which fewer cross-cultural studies have researched.  相似文献   

Imagining the Singapore “Nation” and “Identity”: The role of the media and National Education     

Aaron Koh Faculty of Education 《Asia Pacific Journal of Education》2005,25(1):75-91

This article presents an analysis of two state ideological apparatuses in Singapore to understand how the city-state constructs its sense of nationhood and national identity. The analysis shows how Singapore uses the media to represent its impoverished national identity, and through a state-led curriculum intervention, uses National Education to re-mediate its lack of a national identity. The conclusion points to the difficulties and paradoxes of Singapore's national project of constructing a preferred (national) identity over other identities.  相似文献   

Examining Chinese vocabulary knowledge in Taiwanese first- and second graders using confirmatory factor analysis     

Koh  Poh Wee  Ku  Yu-Min  Chen  Xi 《Reading and writing》2020,33(2):293-312

How the construct of vocabulary is defined remains unclear although multiple theories have been put forth. In light of the lack of empirical work investigating the dimensionality of vocabulary knowledge in Chinese, the present study investigated the factor structure of Chinese print vocabulary in a sample of 111 Taiwanese children in Grades 1 and 2. Participants completed six written measures designed to assess breadth and depth of vocabulary knowledge in receptive or expressive formats. Three hypothesized models corresponding to (1) a unidimensional model on which all six measures loaded onto, (2) a 2-factor model comprising breadth and depth dimensions, and (3) a 2-factor model consisting of receptive and expressive dimensions, were compared using confirmatory factor analyses. Results indicated that the unidimensional model was preferred over two dimensional models, indicating that it is useful to view Chinese vocabulary as a holistic construct rather than as comprising separable dimensions among young Taiwanese children.

Art and Design Education in the Ecology of Care     

Michael Koon Boon Tan 《The International Journal of Art & Design Education》2019,38(4):878-886

In the light of challenges arising from contemporary issues such as inclusivity, sustainability and justice, the connections between art, design and caring appears to be pertinent. What role can artists and designers play in the ecology of care? How can we lead art and design students to connect and lend their creative skills to care needs? Drawing on the ethics of care and a relational view on health this article highlights the various teaching approaches and initiatives introduced at Nanyang Technological University, Singapore, to support and guide students to realise various art and design for health and wellbeing projects that provide opportunities for students to part take in ecology of care using their creative skills. Although creative explorations at the intersection of art, design and caring is still at an early stage, outcomes from this ongoing effort have been encouraging in response to the shifting social needs to create a more inclusive and flourishing society in Singapore.  相似文献   

Stakeholders’ perceptions and recommendations of a high school leadership development programme for athletes in Singapore     

Koon Teck Koh  Leong Seng Morris Koh  Gordon A. Bloom  Todd M. Loughead 《Asia Pacific Journal of Education》2020,40(2):197-211

ABSTRACT

This study examined the perceptions of key stakeholders of a high school athlete leadership development training programme. Participants included 36 athletes (males = 23, females = 13) from two team sports (rugby n = 11 and volleyball n = 6) and two individual sports (bowling n = 8 and table tennis n = 11), as well as four coaches representing each of these sports and four teachers. Individual interviews were conducted for coaches, teachers, and athlete leaders, while athletes took part in focus group interviews. Inductive thematic analysis was used to analyse all data sets. Results showed that the athlete leadership programme developed qualities such as responsibility, role modelling, motivation, communication, perseverance, and team unity that would help athlete leaders perform their roles and responsibilities. The results also highlighted some limitations including earlier involvement from key stakeholders, tailored training for athlete leaders, and a more effective transfer of learning.  相似文献

Measures of Teachers' Workload     

Ong Hoon Liang  Tan Yoke Yin  Koh Yong Guan 《Asia Pacific Journal of Education》1985,7(1):72-74

The measurement of teachers' workload has till now been subjective. Teachers feel that they have a great responsibility to their pupils and to society and their workload heavy, while non-teachers may have different views. This debate occurs even amongst teachers teaching different subjects and levels in a school as well as amongst teachers in different schools. A comparison of teachers' workload in different countries is also particularly difficult because of different class sizes, curriculum time, etc. It is therefore essential to provide a quantitative and objective measure for evaluating teachers' workload. This measure can then be used as a reference by school principals when allocating extra duties to teachers. It is also useful to education authorities when deploying teachers to various schools in centralized education systems.  相似文献   

Effects of Practical Experience and Sequential Skills in Map Reading     

Liaw Beng Teck 《Asia Pacific Journal of Education》1989,10(1):55-59

The study was carried out to examine the effects of practical experience and sequential skills on achievement in map reading among secondary one pupils in Singapore. A total of 144 pupils in four secondary one (Express) classes participated in the study. Each class ws randomly assigned to one of the four treatment groups, where two teaching methods, i.e. practical learning and direct-teaching, and two types of curriculum structure, i.e. hierarchical sequence and non-hierachical sequence, were compared. The experiment consisted of eight weeks of teaching after which a post-test and a delayed post-test were administered to establish the effects of each treatment. Findings showed that practical experience and sequential skills in map reading would have a positive effect on pupil performance and retention of the acquired skills.  相似文献
