INTRODUCTION Recent techniques based on oligonucleotide or cDNA microarrays allow the expression level of thousands of genes to be monitored in parallel (Golub et al., 1999). A critically important factor for cancer diagnosis and treatment is the reliable prediction of tumor progression. A remarkable advance for mo- lecular biology and for cancer research is cDNA mi- croarray technology. cDNA microarray datasets havea high dimensionality corresponding to the large number of genes monit…  相似文献   

Comparing state hegemonies: Chinese universities in postwar Singapore and Hong Kong     

Ting-Hong Wong 《British Journal of Sociology of Education》2005,26(2):199-218

After World War II, Chinese residents of Singapore demanded the establishment of local Chinese universities. The ruling regime, however, which was under the shadow of the neighboring Malay‐dominated Malay Peninsula, was forced to suppress the development of such schools. In Hong Kong, the British needed to install a Chinese university to counter Beijing’s and Taiwan’s campaigns for recruiting students from the colony. As Hong Kong was a monoracial Chinese society, the government, not having to worry about the reaction of other indigenous groups, met this challenge by founding a fully recognized Chinese university. This research demonstrates that under diverse backgrounds of racial politics, state authorities have unequal latitudes to accommodate the educational institutions of subordinated racial groups. It also reveals that state education policies in small and dependent settings, unlike those in big and sovereign nations, are more susceptible to pressures from external powers and influences from the metropolis. These findings urge scholars to pay more attention to the factor of race and use comparative methods when employing the theories of state and hegemony to investigate education and power.  相似文献   

To click or not to click: Effectiveness of rating classroom behaviors on academic achievement with tablets     

Weiyun Chen  Xiaoqing Gu  Lung-Hsiang Wong 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(1):440-455

Due to the time constraint and lack of concise contextualized classroom behavior indicators, current typical primary school classroom behavior management practices are ad-hoc and lack historical data support. To circumvent these problems, we designed a tablet-based classroom behavior management system (CBMS) for a primary school setting. The CBMS aids teachers in establishing concise and consistent behavioral expectations based on teaching experience and expertise, thus allowing them to conveniently provide timely feedback on pupils’ performance and log ratings on a daily basis. We conducted a 1.5 years field study in a primary school Chinese course in East China, in which 124 pupils in the first grade and four Chinese teachers participated. The analysis of recorded data indicates that teachers’ daily behavioral ratings are positively correlated with their pupils’ academic achievements. The behavior rating strategy and indicators in CBMS can act as a substitute in promoting pupil's academic achievements. Our proposed system shows the feasibility and potential of handheld computer-based assessment strategy in implementing cost-effective classroom organization practices for low grade-level primary school pupils.  相似文献   

The learning community narrative: An essential first step in creating and sustaining program identity     

Emilly Borthwick‐Wong  Janna Jones 《About Campus》2012,17(2):9-14

As individuals, we often come to understand our identity through our stories. Emilly Borthwick‐Wong and Janna Jones argue that the same is true for educational programs; a successful, long‐term educational program must be able to communicate its purpose and importance in an easily told narrative.  相似文献

Is there creativity in design? From a perspective of school design and technology in Hong Kong     

Yi Lin Wong  Kin Wai Michael Siu 《Asia Pacific Education Review》2012,13(3):465-474

As creativity is likely to become a crucial aspect of living in the future, it is important for educators to teach students to think creatively when solving constantly evolving and increasingly complex problems. Supported by the idea that creativity can be taught and learnt, elements of creativity are now embedded in secondary school education. Among all school subjects, design and technology (D&T) is one of the best examples for fostering and cultivating students?? creativity, as the subject offers creative activities that enable students to realize their ideas in the context of the real world. This paper analyzes the creative elements in the D&T curriculum in Hong Kong as seen in the exemplar projects on the Education Bureau website. Some problems and difficulties encountered in fostering creativity in the context of Hong Kong are identified, based on the current teaching environment. The paper also draws attention to East Asian beliefs and implicit theories, which greatly influence teachers?? underlying assumptions about learning and teaching, and at the same time notes that these beliefs may be detrimental to the development of creativity among students. The paper then identifies the problems and inadequacies in fostering creativity in design at the secondary school level and expects to raise awareness of the importance of creativity in D&T.  相似文献   

The capstone experience: student and academic perspectives     

Keith Thomas  Kin-chi Wong  Yi-ching Li 《高等教育研究与发展》2014,33(3):580-594

A principal consideration in recent cross-sector educational reforms in Hong Kong is ensuring that undergraduate programmes prepare students for the future workplace, a factor that has made the capstone a central feature of the new four-year curriculum. This paper discusses a study that explored the final-year student experience based on a final-year project (FYP). Both recent graduate and final-year student feedbacks reveal some uncertainty and a lack of confidence over successful transition that graduates attribute to an overtly research focus in the current design of FYPs. Inviting comment from senior academics allows a fuller picture of the rationale behind, and administrative considerations in, conducting a capstone experience. This formative study highlights specific features in designing a capstone experience and the need for academic engagement in order to support the desired outcome of graduate employability.  相似文献   

Teachers’ perceptions of and responses to student evaluation of teaching: purposes and uses in clinical education     

Wai Yee Wong  Karen Moni 《Assessment & Evaluation in Higher Education》2014,39(4):397-411

Student evaluation of teaching (SET) only becomes an effective tool for improving teaching and learning when the relevant stakeholders seriously consider and plan appropriate actions according to student feedback. It is common practice in medical education to provide clinical teachers with student feedback. However, there is limited evidence about how teachers in higher education, and medical education in particular, systematically apply student feedback to improve the quality of their teaching practice. The focus of this case study was to examine clinical teachers’ perceptions of and responses to SET with respect to its purposes and uses for enhancing their teaching. An explanatory sequential mixed methods approach was employed to collect both quantitative and qualitative data from the clinical coaches. These clinical coaches perceived the main purpose of student evaluation as quality assurance, and were moderately receptive to student feedback. Four key factors enabling or inhibiting their responses were revealed: institutional requirements, operational practices, personal biases and provision of support. Future research should further explore the interrelationships among the above factors as the core mechanism in influencing clinical teachers’ perceptions of and responses to student evaluation.  相似文献   

Technical boys and creative girls: the career aspirations of digitally skilled youths     

Billy Wong  Peter E. J. Kemp 《Cambridge Journal of Education》2018,48(3):301-316

Digital technology is increasingly central to our lives, particularly among young people. However, there remains a concern from government and businesses of a digital skills gap because many youths, especially girls, tend to be consumers rather than creators of technology. Drawing on 32 semi-structured interviews with digitally skilled teenagers (aged 13–19), this article investigates their digital career aspirations and examines how identities and discourses of gender can interact with the type of digital careers that are of interest to these youths. While it was found that digitally skilled young people still articulate traditional gendered discourses of digital competence, especially around technical abilities, the growing importance of creativity as a career pathway into digital technology is highlighted. Implications of the findings are discussed in relation to the new computing curriculum in England, which prioritises technical computing skills, and the discontinuation of Information and Communications Technology (ICT), which facilitates a broader usage of software and digital productivity.  相似文献   

Reliability and Validity of a Chinese Version of the Career Decision-Making Difficulties Questionnaire     

Peter A. Creed  Wong Oi Yin 《International Journal for Educational and Vocational Guidance》2006,6(1):47-63

This study tested the applicability of the 34-item CDDQ (Gati &; Saka, 2001) for use with adolescents from the Peoples Republic of China. The study devised a Chinese version of the scale using translation and back-translation, administered it to a sample of 514 Chinese adolescents, tested the psychometric properties of the scale in terms of factor structure and reliability, and examined its validity by testing associations with demographic variables (age, gender, paid work experience, socioeconomic status, and academic achievement) and scales tapping career decision-making self-efficacy and barriers. Results identified two stable factors for the CDDQ, namely Lack of Information and Inconsistent Information, but failed to confirm the third CDDQ factor of Readiness to make a career decision. Factor structure and reliability for the two identified factors were sound, and these factors related in the expected directions to demographic variables and the other career scales. Implications for use of the CDDQ in China are highlighted, and recommendations are made for the revision of the Readiness dimension.  相似文献
