Does big-fish–little-pond effect always exist? Investigation of goal orientations as moderators in the Hong Kong context     

Rebecca Wing-yi Cheng  Dennis M. McInerney  Magdalena Mo Ching Mok 《教育心理学》2014,34(5):561-580

The big-fish–little-pond effect (BFLPE) posits that students with the same ability will have higher academic self-concepts when they are in low-ability classes than in high-ability classes. Our research puts the BFLPE under scrutiny by examining goal orientations as the moderators that may affect the size of the BFLPE. We collected data on mathematics self-concept, mathematics ability and goal orientation from 7334 Hong Kong junior secondary school students in 201 classes. We hypothesised that the BFLPE would be exacerbated for students who endorsed high extrinsic goals while the BFLPE would be attenuated for students who endorsed high intrinsic goals. However, the results did not fully support the hypothesis. We found that students who were highly motivated in general (both intrinsic and extrinsic) experienced stronger BFLPE. The implications of the findings are discussed.  相似文献   

Assessing South China (Guangzhou) High School Students’ Views on Nature of Science: A Validation Study     

Feng Deng  Ching Sing Chai  Chin-Chung Tsai  Tzung-Jin Lin 《Science & Education》2014,23(4):843-863

Research on students’ views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students’ VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely “Accumulative-Empirical Source” and “Pragmatic Justification” which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.  相似文献   

Periodontal status and associated risk factors among childbearing age women in Cixi City of China     

Yan-min WU  Jia LIU  Wei-lian SUN  Li-li CHEN  Li-guo CHAI  Xiang XIAO  Zheng CAO 《Journal of Zhejiang University. Science. B》2013,14(3):231-239

Objective:To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health.Methods:The study was conducted on childbearing age women in Cixi,a city in Zhejiang Province in the southeast of China.A total of 754 women participated in periodontal examination while receiving prenatal care.Data of the women were collected from the Cixi Family Planning Commission and during an interview.Clinical periodontal indices,such as bleeding on probing(BOP),probing depth(PD),and clinical attachment level(CAL) were measured during the examination.Statistical analysis on subject-based data was performed.Results:The prevalence of periodontal disease among childbearing age women in Cixi was high(84.7%).A significant association was found between the disease and educational level,pregnancy,taking oral contraceptives,stress,alcohol consumption,overweight,dental visit,and teeth brushing(P<0.05).Women who suffered periodontal disease showed deep PD,obvious BOP,and clinical attachment loss.Among this population,pregnancy was closely associated with higher BOP percentage;teeth brushing no more than once per day or brushing for less than 1 min(P<0.001) after adjusting for age and stress.Conclusions:The periodontal status of childbearing age women in Cixi needs to be improved urgently.Attention towards the periodontal health should be warranted,especially for those in special statuses and with poor awareness.  相似文献   

Political bias in the news coverage of Taiwan's first presidential election: A comparative analysis of broadcast TV and cable TV news     

Ven‐hwei Lo  Pu‐tsung King  Ching‐ho Chen  Hwei‐lin Huang 《亚洲交流杂志》2013,23(2):43-64

This research examines how TV reported the campaign and the candidates during Taiwan's first‐ever presidential election in 1996.

A content analysis of evening news coverage of six TV stations indicated that the state‐owned broadcast TV stations were far more likely than the privately owned cable TV stations to give a greater amount of coverage and soundbites to the ruling party presidential and vice presidential candidates, using the ruling party officials as principal news sources. The TV Stations’ coverage also contained more news favourable to the ruling party candidates than to other candidates.

The future may well see a turning point in TV election coverage as well as in general news coverage in Taiwan. The three state‐owned broadcast TV stations face competition from privately owned cable TV stations and may soon be confronted with the loss of public trust and audience, unless they can provide fair and balanced news free from government control.  相似文献   

Exploring the Structural Relationships between High School Students’ Scientific Epistemological Views and their Utilization of Information Commitments toward Online Science Information     

Chia‐Ching Lin 《International Journal of Science Education》2013,35(15):2001-2022

The main purpose of this study was to examine the structural relationships between scientific epistemological views (SEVs) and information commitments (ICs) of high school students in Taiwan. Data were collected from 486 Taiwanese high school students via two self‐reporting instruments: one was the SEV questionnaire, including five scales for representing students’ views toward scientific knowledge; and the other was the ICs survey, involving six scales for exploring their evaluative standards and searching strategies of online science information. Structural equation modelling analysis was used to examine the relationships between the aspects of SEVs and ICs. The results of the measurement model confirmed that both the SEVs and ICs instruments had highly satisfactory validity and reliability. The structural equation modelling analysis further indicated that students’ SEVs guided their evaluative standards and searching strategy when dealing with Web‐based science information. For example, students who viewed scientific knowledge as more changeable and tentative significantly tended to adopt a more sophisticated evaluative standard, such as carefully inspecting the content of web sites for judging the usefulness. The findings in general suggested that students with more constructivist‐oriented SEVs might develop more advanced standards and searching strategy toward online scientific information to derive great benefit from Web‐based environments. Consequently, the role of SEVs should be highlighted as increasingly metacognitive engagement with online science information.  相似文献   

“感觉”的运用实现了科学歌唱发声状态培养的简化     

柴伦党 《桂林师范高等专科学校学报》2013,27(1):139-141

一切的声乐技能都是靠自己的意识来控制发声器官的,按照意识预定要求进行动作结果的。发声的各个器官的互相搭配其实也是人的一种本能的意识反应,建立科学发声状态是通过自身感觉的调控,使复杂的肌肉运动准确化、歌唱运用共鸣和呼吸合理化、技巧的掌握简单化,最后实现演唱的自动化。  相似文献

High school students’ scientific epistemological beliefs,motivation in learning science,and their relationships: A comparative study within the Chinese culture   总被引：1，自引：0，他引：1  

Tzung-Jin Lin  Feng Deng  Ching Sing Chai  Chin-Chung Tsai 《International Journal of Educational Development》2013

This study explored the differences in high school students’ scientific epistemological beliefs (SEBs), motivation in learning science (MLS), and the different relationships between them in Taiwan and China. 310 Taiwanese and 302 Chinese high school students’ SEBs and MLS were assessed quantitatively. Taiwanese students generally were more prone to believe that scientific reality is invented, the development of scientific knowledge is culture-dependent, and scientific knowledge is always changing and its status is tentative than the Chinese students were. Yet, the Taiwanese students perceived higher test anxiety in science than the Chinese students did. Moreover, Chinese students who have a stronger belief that science knowledge is changing and tentative are more likely to perceive themselves as having higher test anxiety in science. The results suggest that the role of culture might have an impact on students’ SEBs and their MLS.  相似文献
