Enhancing Undergraduate Research Experience Through a Food Science Research Project     

Yee Ming Lee  Donna Burnett 《Journal of Food Science Education》2019,18(1):11-20

Engaging undergraduate students in research has become increasingly important due to its potential benefits (for example, increased intention to pursue postgraduate study and enhanced understanding of theoretical knowledge). This study investigated whether a comprehensive food science research project that was incorporated into the laboratory component of an Experimental Study of Foods course would enhance student knowledge, confidence, and interest in research. A total of 84 students participated in two sections of the laboratory (2016, n = 39; 2017, n = 45). Scores for pre and posttests and questionnaires were used to determine if the differences in knowledge scores and ratings for confidence in doing research were significant. Knowledge scores indicated that participants were knowledgeable about research at baseline (2016, 7.31 ± 1.15; 2017, 6.89 ± 0.1.21; maximum of 10 points). Results of the t‐tests showed that the change in knowledge scores before and after the project was not statistically significant; however, the level of confidence in performing various research skills (for example, identify research questions, formulate hypotheses, design an experiment) significantly increased upon project completion. In general, students demonstrated favorable attitudes toward the research project at the end of this project. Qualitative responses were organized into three themes that related to the “input” (elements that made the project successful), “process” (how the project was conducted), and “outcomes” (reported gains or benefits) of the project. Recommendations were made in terms of mentorship, research guidelines and topics, and group culture to improve future projects.  相似文献   

Enhancing orthographic knowledge helps spelling production in eight-year-old Chinese children at risk for dyslexia     

Leong CK  Loh KY  Ki WW  Tse SK 《Annals of dyslexia》2011,61(1):136-160

We investigated the effects of enhancing orthographic knowledge on the spelling of Chinese characters and words in 131 eight-year-old Chinese children at risk for dyslexia. The traditional approach (37 children) emphasizing memory and repeated writing was the control condition. The analytic and synthetic approach (ASA, 33 children) stressed insight into character structure. The integrated analytic and synthetic approach added to ASA self-correction and metacognitive activities (INA, 61 children). The children were first asked to write down as many words as possible associated with pictures of home, school, and community; the correctly written words formed the baseline information. The children were then instructed by their classroom teachers in six especially designed short texts and assessed in eight measurable bujian or radical tasks subserving three constructs: morpheme completion, bujian analysis and synthesis and bujian compounding. Multivariate analyses of variance showed that the children in the INA condition outperformed those in the other conditions in three of the measurable bujian tasks. A confirmatory factor analysis verified the stability of the eight tasks and their clustering into three constructs. From these results, we tentatively propose a “bujian sensitivity hypothesis” as a means of helping young Chinese children at risk for spelling disorders.  相似文献   

Identifying affective domains that correlate and predict mathematics performance in high-performing students in Singapore     

Siew Yee Lim  Elaine Chapman 《教育心理学》2015,35(6):747-764

Past studies have shown that distinct yet highly correlated sub-constructs of three broad mathematics affective variables: (a) motivation, (b) attitudes and (c) anxiety, have varying degree of correlation with mathematics achievement. The sub-constructs of these three affective constructs are as follows: (a) (i) amotivation, (ii) external regulation, (iii) introjection, (iv) identification, (v) intrinsic motivation; (b) (i) enjoyment of mathematics, (ii) self-confidence in mathematics, (iii) perceived value of mathematics; (c) (i) anxiety with mathematics and (ii) ease with mathematics. This study identifies, both within and across these three affective variables, the key sub-constructs that educators should focus upon when selecting learning process variables for mathematics achievement. Results were analysed using a series of stepwise regression analyses using data from 1018 Grade 12 students enrolled in a top pre-tertiary institution in Singapore, both for concurrent and predictive relationships, and also for both genders. Results of this study showed that after taking into account self-confidence in mathematics and ease with mathematics, all other sub-constructs of mathematics motivation, attitudes and anxiety were not significantly correlated with mathematics achievement. This is true for both concurrent and predictive relationships, and for both genders. Implications of the results of this study are twofold. First, results of this study provide educators with priority affective variables to focus upon in their efforts to enhance performance in mathematics via the affective domain. Second, in situations where administration time is limited, it may be possible to consider only self-confidence and ease with mathematics when investigating relationships between affect and mathematics achievement.  相似文献   

Globalisation and localisation enmeshed—towards a framework for the development of guidance curriculum in Hong Kong     

Pattie Yuk Yee Luk‐Fong 《Globalisation, Societies & Education》2005,3(1):83-100

Hong Kong’s 150 years of colonisation by the British is a classic example of how globalisation comes into direct contact with a local Chinese culture and creates cultural hybridities. The paper presents a framework for developing a hybrid guidance curriculum, drawing together western traditions of developmental contextualism in guidance and Chinese traditions of Confucian humanism in moral education. The core of the framework is a hybrid self, integrating the individualist and the embedded self. The paper highlights the importance of culture and context in considering school guidance and the ‘fluid’ and dynamic nature of ‘glocalisation’ working towards integration.  相似文献   

The development of personal,intercultural and professional competence in international field experience in initial teacher education     

Tang  Sylvia Yee Fan  Choi  Pik Lin 《Asia Pacific Education Review》2004,5(1):50-63

This paper reports a qualitative case study of four preservice student teachers’ professional learning experiences in an international field experience programme situated in the language and cultural immersion component of a PGDE(Primary) Programme in Hong Kong. Two of the student teachers undertook the international field experience in Australia and Canada. The other two had their “non-local” field experience in mainland China1. The findings reveal student teachers' development in personal and intercultural competence in cross-cultural experiences. Their professional learning experiences in the action context, socio-professional context, and supervisory context of the cross-cultural school settings, and their reflection upon these experiences constituted the development of their professional competence. Suggestions for improvement of the international field experience programme and implications for future research are discussed.  相似文献   

When Do Honors Programs Make the Grade? Conditional Effects on College Satisfaction,Achievement, Retention,and Graduation     

Nicholas A. Bowman  KC Culver 《Research in higher education》2018,59(3):249-272

Many people within and outside of higher education view honors programs as providing meaningful academic experiences that promote learning and growth for high-achieving students. To date, the research exploring the link between honors participation and college grades and retention has obtained mixed results; some of the seemingly conflicting findings may stem from the presence of methodological limitations, including the difficulty with adequately accounting for selection into honors programs. In addition, virtually no research has explored the conditions under which honors programs are most strongly related to desired outcomes. To provide a rigorous examination of the potential impact of this experience, this study conducted propensity score analyses with a large, multi-institutional, longitudinal sample of undergraduates at 4-year institutions. In the full sample, honors participation predicts greater college GPA and 4-year graduation, while it is unrelated to college satisfaction and retention. However, these results differ notably by institutional selectivity: Honors participation is associated with greater college GPA, retention to the third and fourth years of college, and 4-year graduation at less selective institutions, but it is significantly related only to GPA at more selective institutions. These relationships are also sometimes larger among students from historically underrepresented groups.  相似文献   

Assessment of the phase synchronization effect in modal testing during operation     

Zhi Chao Ong  Hong Cheet Lim  Shin Yee Khoo  Zubaidah Ismail  Keen Kuan Kong  Abdul Ghaffar Abdul Rahman 《浙江大学学报(A卷英文版)》2017,18(2):92-105

The impact-synchronous modal analysis (ISMA), which uses impact-synchronous time averaging (ISTA), allows modal testing to be performed during operation. ISTA is effective in filtering out the non-synchronous cyclic load component, its harmonics, and noises. However, it was found that at operating speeds that coincide with the natural modes, ISMA would require a high number of impacts to determine the dynamic characteristics of the system. This finding has subsequently reduced the effectiveness and practicality of ISMA. Preservation of signatures during ISTA depends on the consistency of their phase angles on every time block but not necessarily on their frequencies. Thus, the effect of phase angles with respect to impact is seen to be a very important parameter when performing ISMA on structures with dominant periodic responses due to cyclic load and ambient excitation. The responses from unaccounted forces that contain even the same frequency as that contained in the response due to impact are diminished with the least number of impacts when the phase of the periodic responses is not consistent with the impact signature for every impact applied. The assessment showed that a small number of averages are sufficient to eliminate the non-synchronous components with 98.48% improvement on simulation and 95.22% improvement on experimental modal testing when the phase angles with respect to impact are not consistent for every impact applied.  相似文献   

Women teachers in Hong Kong: stories of changing gendered identities     

Yuk Yee Pattie Luk-Fong  Marie Brennan 《Asia Pacific Journal of Education》2010,30(2):213-229

In a time of mass schooling in most parts of the world, the discourse of the “woman primary teacher” is often the subject of discourse. Yet most stories of these women teachers emerge from other (Western) contexts, with little known about how changing education processes affect the gendered identities of women in other cultural settings. This paper explores how women teachers negotiate their gendered identities in Hong Kong, where modernization has already mingled with the indigenous Chinese culture. It provides the stories of four Chinese women teachers as they engage in ongoing construction and negotiations of gendered identities over their life histories in Hong Kong. All are ethnically Chinese, of different ages and at different stages of their personal and professional lives, and all have grown up in Hong Kong. A framework of post-colonial concepts of hybridity and border crossing helps to suggest how identity resources develop in relation to a range of contemporary practices which are experienced as both pressures and opportunities. These Chinese women teachers' identities are seen to be complex, fluid and multi-faceted, continually under construction in their daily lives, with changes experienced in both work and family settings.  相似文献

Direction dependence of displacement time for two-fluid electroosmotic flow     

Lim CY  Lam YC 《Biomicrofluidics》2012,6(1):12816-1281617

Electroosmotic flow that involves one fluid displacing another fluid is commonly encountered in various microfludic applications and experiments, for example, current monitoring technique to determine zeta potential of microchannel. There is experimentally observed anomaly in such flow, namely, the displacement time is flow direction dependent, i.e., it depends if it is a high concentration fluid displacing a low concentration fluid, or vice versa. Thus, this investigation focuses on the displacement flow of two fluids with various concentration differences. The displacement time was determined experimentally with current monitoring method. It is concluded that the time required for a high concentration solution to displace a low concentration solution is smaller than the time required for a low concentration solution to displace a high concentration solution. The percentage displacement time difference increases with increasing concentration difference and independent of the length or width of the channel and the voltage applied. Hitherto, no theoretical analysis or numerical simulation has been conducted to explain this phenomenon. A numerical model based on finite element method was developed to explain the experimental observations. Simulations showed that the velocity profile and ion distribution deviate significantly from a single fluid electroosmotic flow. The distortion of ion distribution near the electrical double layer is responsible for the displacement time difference for the two different flow directions. The trends obtained from simulations agree with the experimental findings.  相似文献
