Effects of Diagrams on Mathematics Performance     

Lily Yee-Sheung Wong  Loh Mei Yoke  Ng Lay Pheng  Mak Wai Han 《Asia Pacific Journal of Education》1992,12(2):26-34

Research on the facilitative effect of diagrams on solving mathematics problems is both inconsistent and inconclusive. This study investigates the effects of diagrams on 124 Singaporean pupils in three classes: Primary One and three, and Secondary One. Pupils' performance was measured with the use of teacher-written mathematics problems in the form of worksheets. Number of errors made on problems accompanied with and without diagrams were compared. Whether or not pupils benefit from diagrams was estimated by their patterns of errors made in the presence or absence of diagrams. Results both confirm and disconfirm previous findings and shed further light on the use of diagrams in mathematics.  相似文献   

Academic motivations of Yi youths in China: Classmate support and ethnic identity     

Angel Hor Yan Lai  Kin-Yu Wong  Cecilia Lai Wan Chan 《The Journal of educational research》2019,112(4):550-563

To enhance the academic achievements of Yi ethnic minority youths in rural school settings, the authors examined the effect of classmate support and the meditating role of ethnic identity in promoting their academic motivation. Cross-sectional survey data were collected from Yi youths sponsored by a philanthropic organization to attend local schools in Liangshan, rural China (n?=?657; 7–12 years old; 52% boys). Results of structural equation modelling showed that classmate support positively affected ethnic identity-commitment and ethnic identity-exploration, which then had positive impacts on three academic motivation outcomes: intrinsic motivation, extrinsic motivation-external and identified regulation, and extrinsic motivation-introjected regulation. The mediating effects of ethnic identity-exploration and ethnic identity-commitment were statistically significant, except for the pathway from classmate support to extrinsic motivation-introjected regulation via ethnic identity-commitment. The authors found that ethnic identity can be facilitated through building supportive classroom environment for positive academic motivations in Yi youths. Cross-cultural significance of this study is also discussed.  相似文献

Effect of Twinning on Chinese and English Vocabulary Knowledge     

Simpson W.L. Wong  Him Cheung  Mo Zheng  Xiujie Yang  Catherine McBride  Connie Suk-Han Ho  Judy Sze-Man Leung  Bonnie Wing-Yin Chow  Mary Miu Yee Waye 《Child development》2020,91(6):1886-1897

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.  相似文献   

The role of school leadership in Singapore's future-ready school reform     

David Foo Seong Ng  Choun Pei Wong 《European Journal of Education》2020,55(2):183-199

In this paper, we propose that successful education needs to fulfil three purposes while being cognisant of time and context: (a) learning, (b) lifework and (c) well-being. An education system is successful if it can develop future-ready individuals who will continue to learn beyond graduation, take on future lifework, and thrive in a changing society and environment. The future is context-situated and context-dependent. We have chosen to examine the economic, social and environmental context of Singapore to provide insight on the values, skills and knowledge that are required of future-ready learners according to the three purposes. We have compared the trajectories of other high-income nations with those of Singapore. Traditional teaching and learning practices no longer serve us well in the new realities that emerge. Education practices need to evolve in tandem to meet the demands of the 21st century. The roles that school leaders play include creating teaching and learning environments where these practices can be implemented. In our review of leadership practices and concepts, we have found that it is important for school leaders to question existing assumptions of teaching, learning and leadership practices in order to advance the development of 21st century skills, knowledge, values, and habits in learners.  相似文献   

Thermal mixing of two miscible fluids in a T-shaped microchannel     

Xu B  Wong TN  Nguyen NT  Che Z  Chai JC 《Biomicrofluidics》2010,4(4):44102

In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing channel. In the experiments, de-ionized water was employed as the working fluid. Laser induced fluorescence method was used to measure the fluid temperature field in the microchannel. Different combinations of flow rate ratios were studied to investigate the thermal mixing characteristics in the microchannel. At the T-junction, thermal diffusion is found to be dominant in this area due to the striation in the temperature contours. In the mixing channel, heat transfer processes are found to be controlled by thermal diffusion and convection. Measured temperature profiles at the T-junction and mixing channel are compared with analytical model and numerical simulation, respectively.  相似文献   

Targeting HSPA1A in ARID2-deficient lung adenocarcinoma

Somatic mutations of the chromatin remodeling gene ARID2 are observed in ∼7% of human lung adenocarcinomas (LUADs). However, the role of ARID2 in the pathogenesis of LUADs remains largely unknown. Here we find that ARID2 expression is decreased during the malignant progression of both human and mice LUADs. Using two Kras^G12D-based genetically engineered murine models, we demonstrate that ARID2 knockout significantly promotes lung cancer malignant progression and shortens overall survival. Consistently, ARID2 knockdown significantly promotes cell proliferation in human and mice lung cancer cells. Through integrative analyses of ChIP-Seq and RNA-Seq data, we find that Hspa1a is up-regulated by Arid2 loss. Knockdown of Hspa1a specifically inhibits malignant progression of Arid2-deficient but not Arid2-wt lung cancers in both cell lines as well as animal models. Treatment with an HSPA1A inhibitor could significantly inhibit the malignant progression of lung cancer with ARID2 deficiency. Together, our findings establish ARID2 as an important tumor suppressor in LUADs with novel mechanistic insights, and further identify HSPA1A as a potential therapeutic target in ARID2-deficient LUADs.  相似文献   

When marketisation and privatisation clash with socialist ideals: Educational inequality in Urban China     

Ka Ho Mok  Yu Cheung Wong  Xiulan Zhang 《International Journal of Educational Development》2009

In the last two decades, China's education has experienced significant transformations and restructuring on account of privatization and marketization. Unlike the Mao era when the state assumed the major responsibilities in financing and providing education, individuals and families have now to bear increasing financial burdens in paying for education. The marketization and privatization of education has undoubtedly intensified educational inequalities and widened regional disparities between the economically developed areas in the eastern coast and the less economically developed areas in the middle and north-western parts of the country. The growing inequalities in education and the increasing financial burdens presented by education have been a source of social discontentment, which have in turn prompted the central government to revisit its approaches to educational development. This article sets out to examine, how in this wider policy context, China's education has been transformed following the adoption of more pro-competition and market-oriented reform measures. This article is based on intensive secondary data analysis, fieldwork observations, and findings from a household survey conducted in eight different Chinese cities about people's perceived education hardship. The article concludes by considering how the Chinese government has attempted to address the problems of educational inequalities that have intensified on account of two decades of education marketization.  相似文献   

Career decision-making, career barriers and occupational aspirations in Chinese adolescents     

Peter A. Creed  Oi Yin Wong  Michelle Hood 《International Journal for Educational and Vocational Guidance》2009,9(3):189-203

The study tested the relationship between occupational aspirations/expectations (type and status) and decision-making difficulties, efficacy and career barriers in 498 Chinese high school students. Males aspired to investigative and enterprising types, but expected realistic and enterprising ones; females aspired to enterprising and conventional types, but expected conventional and social ones. Students with aspirations/expectations type discrepancies were more likely to be higher achieving females; those with aspirations/expectations status discrepancies had poorer academic achievement, less confidence and perceived more barriers.  相似文献
