Drawing on the variation theory to enhance students’ learning of Chinese characters     

Ho Cheong Lam  Bik May Amy Tsui 《Instructional Science》2013,41(5):955-974

The variation theory of Ference Marton and his collaborators has widely been used as a framework for explaining what can possibly be learned in a particular classroom and what cannot. This paper reports on an experiment that put this theory to test in the context of students’ learning of the orthographic structures of Chinese characters. The experiment was carried out in the classrooms of two primary schools in Hong Kong. In each of the schools, two classes of students were taught differently, as informed by the theory, about the significance of the location of a component in the orthographic structure of a character in relation to whether the component provided a clue to the meaning of the character (called the part–part relations). The results of the experiment are consistent with the prediction of the theory that those students who were given the possibility to experience variation in the locations of components in the orthographic structures significantly outperformed those who were not. The results of the experiment demonstrate the power of the theory in guiding the design of teaching that affords students’ learning to happen.  相似文献   

An analysis of continuous teacher development in Hong Kong     

Ho Ming Ng 《教育政策杂志》2013,28(6):657-672

Education in Hong Kong has developed rapidly since the 70s in parallel with the economic boom. To support such development, the government has invested heavily in initial teacher education and will soon impose professional training and graduate qualifications as prerequisites for entering the profession. Continuous teacher education (CTE), generally regarded as equally important as initial teacher education if not more so, is not given comparable emphasis. This paper aims to study CTE in Hong Kong, including its policy, practice and provision at the system level. Some special features of the system are identified and scrutinized, including ad hoc, policy led, and competence based. The centrally provided CTE is also closely examined in terms of its relevance to the profession, impact on schools, and cost‐effectiveness. The paper ends with a close look at its latest developments, obstacles encountered and prospects.  相似文献   

Research output among the three faculties of business, education, humanities & social sciences in six Hong Kong universities     

Kwok Keung Ho 《Higher Education》1998,36(2):195-208

Academics in Hong Kong universities are urged to increase their research output. This article investigates the measurement of publication outputs among the three faculties of business, education, humanities & social sciences in the six universities of Hong Kong. Data were collected from the 1990–95 annual reports of research and publication outputs of each university. In order to have a fair comparison of publication outputs of each academic, rank, faculty and university, a framework was developed from practical experience and from literature to investigate the problem. Results indicate that the publication outputs of academics in Hong Kong were about the same as other countries in many aspects. Pressing academics for more research publications may raise the figure in the start, but would not necessarily increase the output in the long run.  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   

A Web-Based Virtual Microscopy Platform for Improving Academic Performance in Histology and Pathology Laboratory Courses: A Pilot Study     

Bai-Chin Lee  Sung-Tsang Hsieh  Yih-Leong Chang  Fen-Yu Tseng  Yu-Jung Lin  Yuh-Lien Chen  Shu-Huei Wang  Yu-Fong Chang  Yi-Lwun Ho  Yen-Hsuan Ni  Shan-Chwen Chang 《Anatomical sciences education》2020,13(6):743-758

Virtual microscopy (VM) has been utilized to improve students' learning experience in microscope laboratory sessions, but minimal attention has been given to determining how to use VM more effectively. The study examined the influence of VM on academic performance and teacher and student perceptions and compared laboratory test scores before and after VM incorporation. A total of 662 third-year students studying histology and 651 fourth-year students studying pathology were divided into two groups. The light microscopy (LM) group used a light microscope in 2014 and 2015, while the LM + VM group used the VM platform and a light microscope in 2016 and 2017. Four factors positively predict laboratory scores (R square, 0.323; P < 0.001): (i) the pathology course and test-enhanced learning, (ii) the VM platform and experience, (iii) medical students and lecture scores, and (iv) female students. The LM + VM group exhibited less score variability on laboratory examinations relative to their mean than the LM group. The LM + VM group was also associated with fewer failing grades (F grade; odds ratio, 0.336; P < 0.001) and higher scores (A grade; odds ratio, 2.084; P < 0.001) after controlling for sex, school, course, and lecture grades. The positive effect of the VM platform on laboratory test grades was associated with prior experience using the VM platform and was synergistic with more interim tests. Both teachers and students agreed that the VM platform enhanced laboratory learning. The incorporation of the VM platform in the context of test-enhanced learning may help more students to master microscopic laboratory content.  相似文献   

Mixed Methods Research – Nonverbal Observations of Cultural Convergence in Online and Offline Contexts: Testing Hall’s Low- Vs. High-Context Framework     

Chia-Ling Lynn Ho  Chad Whittle  Michael H. Eaves 《Journal of Intercultural Communication Research》2020,49(4):301-312

ABSTRACT

Extending the existing low- and high-context culture theoretical framework, the current research examined the extent to which globalization has shaped low- and high-context cultures in relation to nonverbal communication. The current study employed an exploratory sequential design mixed research method. The first phase of the study observed cultural convergence evident in people’s nonverbal communication in real life and reported the observations qualitatively. In the second phase of the study, a quantitative content analysis was carried out. The content analysis, namely sentiment analysis, examined the occurrences of people of diverse nationalities expressing their emotions when they provide reviews of airlines on a travel website and empirically test the relevance of low- and high-context theoretical framework in the era of globalization. A total of 85,228 reviews of 592 airlines available on a travel website were downloaded using a web crawler. The qualified records used for analysis included records from the following regions: Africa, Asia, Australia, Latin America, Northwestern Europe, Southern Europe, and United States. An analysis of variance on the number of words people used in writing travel reviews online yielded significant variations among the seven regions. This data also sheds light on cultural convergence.  相似文献   

Automated calibration of 3D-printed microfluidic devices based on computer vision     

Junchao Wang  Kaicong Liang  Naiyin Zhang  Hailong Yao  Tsung-Yi Ho  Lingling Sun 《Biomicrofluidics》2021,15(2)

With the development of 3D printing techniques, the application of it in microfluidic/Lab-on-a-Chip (LoC) fabrication is becoming more and more attractive. However, to achieve a satisfying printing quality of the target devices, researchers usually require quite an amount of work in calibration trials even for high-end 3D printers. To increase the calibration efficiency of the average priced printers and promote the application of 3D printing technology in the microfluidic community, this work has presented a computer vision (CV)-based method for rapid and precise 3D printing calibration with examples on cylindrical hole/post diameters of 0.2–2.4 mm and rectangular hole/post widths of 0.2–1.0 mm by a stereolithography-based 3D printer. Our method is fully automated, which contains five steps and only needs a camera at hand to provide photos for convolutional neural network recognition. The experimental results showed that our CV-based method could provide calibrated dimensions with just one print of the specific calibration ruler to meet user desire. The higher resolution of the photo provides a higher precision in calibration. Subsequently, only one more print for the target device is needed after the calibration process. Overall, this work has provided a quick and precise calibration tool for researchers to apply 3D printing in the fabrication of their microfluidic/LoC devices with average price printers. Besides, with our open source calibration software and calibration ruler design file, researchers can modify the specific setting based on customized needs and conduct calibration on any type of 3D printer.  相似文献   

Preventive Conservation: People,Objects, Place and Time in the Philippines     

Nicole Tse  Ana Maria Theresa Labrador  Marcelle Scott  Roberto Balarbar 《文物保护研究》2018,63(5):274-281

ABSTRACT

Preventive conservation, with its origins grounded in the material fabric of cultural material, is in a period of transformation, with numerous practitioners, in and outside of the field of conservation, considering its broader and holistic objectives. The conventional tools for the assertion of preventive conservation principles, namely the assessment and management of risks to cultural material from the ‘ten agents of deterioration’, have a central focus on the primacy of physical materials and degradation, with less clear relationships with people, place, and time in their modelling. With a case study focus on collections in the Philippines, this paper argues for a practice of preventive conservation that incorporates a balanced assessment and broader thinking around the contexts of objects, people, place, and time. The case studies of ecclesiastical Church collections, and museum environments in the Philippines, demonstrate how the interdependency of objects, people, place and time forms a holistic and conceptual preventive conservation framework. Through a cyclic renegotiation of these four parameters, this paper speculates on the gaps and opportunities for an inclusive view of preventive conservation that is current and more sustainable.  相似文献   

Communication,cognitive processing,and public knowledge about climate change     

Shirley S. Ho  Xiaodong Yang 《亚洲交流杂志》2018,28(5):449-467

This study advances the cognitive mediation model (CMM) by examining the factors behind acquiring knowledge about climate change. Based on a nationally representative survey of Singaporeans (N?=?1,083), this study supported the original CMM. The extended CMM showed that surveillance gratification was positively associated with traditional and online media attention, while social utility was positively associated with online media attention. While attentions to traditional and online media were positively associated with elaboration, online media attention was positively associated with selective scanning. Elaboration was positively associated with knowledge. Implications for theory and practice were discussed.  相似文献
