High School Students’ Motivation to Learn Mathematics: The Role of Multiple Goals     

Chi-hung Clarence Ng 《International Journal of Science and Mathematics Education》2018,16(2):357-375

Using a sample of 310 Year 10 Chinese students from Hong Kong, this survey study examined the effects of multiple goals in learning mathematics. Independent variables were mastery, performance-approach, performance-avoidance, and pro-social goals. Dependent variables included perceived classroom goal structures, teacher’s support, learning motives and strategies, attitudes, and grade aspiration. Based on regression and cluster analyses, this study found convergent evidence supporting the benefits of adopting additional adaptive goals alongside mastery goals. Regression analyses located significant interaction between pro-social goals and mastery goals in predicting higher levels of positive learning attitudes and lower levels of surface learning motives. Cluster analyses confirmed that students endorsing pro-social goals, performance-approach goals and mastery goals in their goal profiles had an adaptive pattern of perceptions, use of strategies, learning motives and grade aspiration in mathematics.  相似文献   

Reimagining Christian Higher Education in China Today     

Peter Tze Ming Ng 《Christian Higher Education》2018,17(4):185-197

This article focuses on the history of Christian higher education in China as a case study, building upon the work of scholars who have been seeking to better understand the identity and distinguishing marks of Christian higher education in a variety of settings worldwide. Although there had been 13 Christian colleges and universities in China before the Communist rule in 1949, such institutions had totally disappeared from China during the early 1950s, only to be revived to a limited extent three decades later due to a resurgence of the study of the history of Christian colleges in the 1980s. As one manifestation of the renewed interest in Christian higher education, in 2014 Yenching University Alumni Association celebrated the 95th anniversary of the founding of Yenching University in Beijing. This indication of interest reflects a new form of Christian presence in higher education in China that is quite different from elsewhere. In this article, the author describes some of the activities taking place over the past three decades in China that merit scholarly attention more broadly.  相似文献   

Low-cost,disposable microfluidics device for blood plasma extraction using continuously alternating paramagnetic and diamagnetic capture modes     

Pilkee Kim  Eng Hui Ong  King Ho Holden Li  Yong-Jin Yoon  Sum Huan Gary Ng  Khuntontong Puttachat 《Biomicrofluidics》2016,10(2)

Blood plasma contains biomarkers and substances that indicate the physiological state of an organism, and it can be used to diagnose various diseases or body condition. To improve the accuracy of diagnostic test, it is required to obtain the high purity of blood plasma. This paper presents a low-cost, disposable microfluidics device for blood plasma extraction using magnetophoretic behaviors of blood cells. This device uses alternating magnetophoretic capture modes to trap and separate paramagnetic and diamagnetic cells away from blood plasma. The device system is composed of two parts, a disposable microfluidics chip and a non-disposable (reusable) magnetic field source. Such modularized device helps the structure of the disposable part dramatically simplified, which is beneficial for low-cost mass production. A series of numerical simulation and parametric study have been performed to describe the mechanism of blood cell separation in the microchannel, and the results are discussed. Furthermore, experimental feasibility test has been carried out in order to demonstrate the blood plasma extraction process of the proposed device. In this experiment, pure blood plasma has been successfully extracted with yield of 21.933% from 75 μl 1:10 dilution of deoxygenated blood.  相似文献   

Provision of early field experiences for teacher candidates in Singapore and how it can contribute to teacher resilience and retention     

Pak Tee Ng  Kam Ming Lim  Ee Ling Low  Chenri Hui 《Teacher Development》2018,22(5):632-650

While teacher retention is a pressing issue for many jurisdictions, Singapore has a relatively low teacher attrition rate. Drawing on the experiences of student teachers from the sole institute for pre-service teacher education in Singapore, this article argues that it is important to expose teacher candidates to a substantial period of school experience as part of the teacher recruitment process. Before they are officially enrolled into pre-service teacher education, the Ministry of Education in Singapore requires all teacher candidates in the Postgraduate Diploma of Education program to go through a compulsory school stint. The authors' research findings show that this exposure to the realities and complexities of teaching can be an important contributor to teacher retention in terms of assessing and promoting teacher candidates’ resilient qualities, such as passion for teaching, self-efficacy beliefs, and positive emotion. In other words, early field experiences can help teacher candidates understand themselves as teachers and assess their own suitability for a teaching career. This study sheds new light on the policies and practices of teacher retention and teacher recruitment strategies.  相似文献   

Retrieval Practice Enhances Analogical Problem Solving     

Sarah Shi Hui Wong  Gavin Jun Peng Ng  Tobias Tempel 《Journal of Experimental Education》2019,87(1):128-138

The impact of retrieval practice on analogical-problem-solving performance was investigated using a complex, educationally relevant task. Participants studied a statistical hypothesis testing scenario and practiced recalling the material or repeatedly studied it. Participants then completed a final test either 5 minutes or 1 week later involving a novel hypothesis-testing scenario that shared an intermediate procedural strategy and superficial and structural similarity with the study scenario but that differed at a specific procedure level. When the final test was given after 5 minutes, no differences in performance were observed across conditions (d = 0.01). Crucially, on the delayed test, retrieval practice produced superior performance than did repeated studying (d = 0.81), whereby participants were better at applying learned knowledge to solve a novel problem.  相似文献   

Effect of suction change on water content and total volume of an expansive clay   总被引：2，自引：0，他引：2  

ZHAN Liang-tong CHEN Ping NG C.W.W. 《浙江大学学报(A卷英文版)》2007,8(5):699-706

A laboratory study was carried out on both natural and compacted specimens to investigate the complex soil-water interaction in an unsaturated expansive clay. The laboratory study includes the measurement of soil-water characteristic curves, 1D free swelling tests, measurement of swelling pressure and shrinkage tests. The test results revealed that the air-entry value of the natural specimen was quite low due to cracks and fissures present. The hydraulic hysteresis of the natural specimen was relatively insignificant as compared with the compacted specimen. Within a suction range 0 to 500 kPa, a bilinear relationship between free swelling strain (or swelling pressure) and initial soil suction was observed for both the natural and compacted specimens. As a result of over-consolidation and secondary structures such as cementation and cracks, the natural specimens exhibited significant lower swelling (or swelling pressure) than the compacted specimen. The change of matric suction exerts a more significant effect on the water phase than on the soil skeleton for this expansive clay.  相似文献   

Mothers’ Goals Influence Their Responses to Children’s Performance: An Experimental Study in the United States and Hong Kong     

Janice Ng  Florrie F. Ng  Eva M. Pomerantz 《Child development》2021,92(6):2317-2334

This research examined the role of mothers’ self-worth and self-improvement goals in their responses to children’s performance in the United States (80% European American) and Hong Kong (100% Chinese). Mothers (N = 330) were induced to prioritize self-worth or self-improvement among children (M_age = 10.24 years; 48% girls) . Mothers induced to prioritize self-worth (vs. self-improvement) used more success-oriented responses in both regions (ds = 0.53 and 0.35). Mothers induced to prioritize self-improvement (vs. self-worth) used more failure-oriented responses only in the United States (d = 0.29). Mothers’ success-oriented responses predicted more positive beliefs and affect in a cognitive task among children (βs = .10–.18). Taken together, the findings support the importance of parents’ goals in the socialization process.  相似文献   

The attitude of civil engineering students towards health and safety risk management: a case study     

A. K. Petersen  J. H. Reynolds  L. W.T. Ng 《European Journal of Engineering Education》2008,33(5-6):499-510

The highest rate of accidents and injuries in British industries has been reported by the construction industry during the past decade. Since then stakeholders have recognised that a possible solution would be to inculcate a good attitude towards health and safety risk management in undergraduate civil engineering students and construction professionals. Consequently, the four accreditation bodies that accredit construction degrees have improved coverage of health and safety risk management. The key issue has now shifted to ensure that Higher Education Centres deliver these requirements. This paper demonstrates innovative assessment methods that have been used to inculcate a safety conscious attitude into undergraduate civil engineering students, and to improve their knowledge of health and safety risk management. Surveys were administered to the students before and after they were subjected to innovative assessment techniques over two semesters in the construction management units. The analyses of the results of the surveys are provided to demonstrate the degree of improvement in the attitude of the students towards, and their knowledge of, health and safety risk management.  相似文献   

Development and Field Test of an Employment Selection Instrument for Teachers in Urban School Districts     

Howard Ebmeier  Jennifer Ng 《Journal of Personnel Evaluation in Education》2005,18(3):201-218

Employment interviews are widely used in the selection of quality teachers, and indeed research confirms administrators’ belief in the validity of the procedure. However, many key recommendations for improving the general reliability of interviews including selecting questions that are job-related and research grounded, including well designed scoring rubrics, and incorporating adaptive variable-length interview designs are generally not well implemented in currently available instruments. Furthermore, emerging research suggests the need for specially tailored interviews that assess attitudes and pre-dispositions deemed essential to teachers’ effectiveness in certain high attrition environments like urban schools. This study describes the development and initial field-test results of a computer based, adaptive interview with an additional domain included for teachers in urban areas. The instrument is based on careful analysis of the suggestions from the extant literature base about effective employment interview techniques, effective general teaching practices, and sound teaching strategies in urban schools. By comparing the interview scores of 30 teachers with varying effectiveness ratings provided by administrators in one urban district, significant correlations were found. Regression analysis indicated a significant amount of variance in teachers’ effectiveness ratings could be predicted from their scores on the interview instrument.

Experiences of Counselor Education Doctoral Student Mothers With Young Children     

Brooke Lundquist  Deborah Rubel  Kok-Mun Ng 《Counselor Education & Supervision》2020,59(4):267-282

We explored the mothering experiences of 11 counselor education doctoral student mothers who have at least one young child under the age of 5. Six themes emerged from the study, including ambivalence, increased use of coping mechanisms, striving for balance, “superwoman syndrome,” indistinguishable roles, and leading by example.  相似文献
