Exploring the parallelism between change in students' conceptions and historical change in the concept of inertia     

Dr Jinwoong Song  Sook-Kyoung Cho  Byung-Hoon Chung 《Research in Science Education》1997,27(1):87-100

This study investigates students' conceptions of inertia and compares these conceptions with historical change in the concept. A total of 736 students from four different age groups (i.e., age 11, 13, 15 and 17) participated in the survey. Questions in the questionnaire represent problems related to the concept of inertia which have been argued by past scientists such as Aristotle, Buridan, Galileo, and Newton. The questionnaire contained three questions, each concerned with one of the following applications of inertia: natural motion, the motion of a flying spear, and the falling motion of a stone on a moving ship. The results of the survey showed that there were considerable similarities as well as dissimilarities between students' conceptions and the views of past scientists. It is suggested that this kind of comparison studies would give useful background information on change in students' conceptions. To this day every student of elementary physics has to struggle with the same errors and misconceptions which then had to be overcome, and on a reduced scale, in the teaching of this branch of knowledge in schools, history repeats itself every year.

How research data is cited in scholarly literature: A case study of HINTS     

JungWon Yoon  EunKyung Chung  Jae Yun Lee  Jihyun Kim 《Learned Publishing》2019,32(3):199-206

This study investigated how Health Information National Trends Survey (HINTS) data from the U.S. National Cancer Institute (NCI) was cited in the scholarly literature. It addressed the following research questions: (1) What patterns of citations exist among authors of research articles using HINTS data? and (2) How is the citation format of HINTS data characterized? We collected scholarly articles that used HINTS data as primary or secondary data for analysis from Web of Science databases and HINTS publications on the NCI website. Among the resulting 250 articles, we identified citations to HINTS data themselves (data citations) and those to HINTS‐related documents (data‐related citations). Among the 250 articles, 156 articles (62.4%) cited HINTS data or HINTS‐related documents; only 29 articles (11.6%) cited HINTS data, while 127 (50.8%) cited HINTS‐related documents. Both data and data‐related citations increased over time. Data citation format varied, and 13 different compositions of citation elements were identified. Author, Title, and Location (URL) were common elements. The frequent use of URLs is undesirable due to URL instability. Furthermore, the data citations showed not only various compositions of citation elements but also ill‐defined element formats. Standardized citation formats are therefore needed.  相似文献   

Browsing software of the Visible Korean data used for teaching sectional anatomy     

Shin DS  Chung MS  Park HS  Park JS  Hwang SB 《Anatomical sciences education》2011,4(6):327-332

The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for students but could be more advanced. The objective of this research was to present browsing software developed from the Visible Korean images that can be used for teaching sectional anatomy. One thousand seven hundred and two sets of MRIs, CTs, and sectioned images (intervals, one millimeter) of a whole male cadaver were prepared. Over 900 structures in the sectioned images were outlined and then filled with different colors to elaborate each structure. Software was developed where four corresponding images could be displayed simultaneously; in addition, the structures in the image data could be readily recognized with the aid of the color-filled outlines. The software, distributed free of charge, could be a valuable tool to teach medical students. For example, sectional anatomy could be taught by showing the sectioned images with real color and high resolution. Students could then review the lecture by using the sectioned and color-filled images on their own computers. Students could also be evaluated using the same software. Furthermore, other investigators would be able to replace the images for more comprehensive sectional anatomy.  相似文献   

Item Response Theory Models for Performance Decline During Testing     

Kuan‐Yu Jin  Wen‐Chung Wang 《Journal of Educational Measurement》2014,51(2):178-200

Sometimes, test‐takers may not be able to attempt all items to the best of their ability (with full effort) due to personal factors (e.g., low motivation) or testing conditions (e.g., time limit), resulting in poor performances on certain items, especially those located toward the end of a test. Standard item response theory (IRT) models fail to consider such testing behaviors. In this study, a new class of mixture IRT models was developed to account for such testing behavior in dichotomous and polytomous items, by assuming test‐takers were composed of multiple latent classes and by adding a decrement parameter to each latent class to describe performance decline. Parameter recovery, effect of model misspecification, and robustness of the linearity assumption in performance decline were evaluated using simulations. It was found that the parameters in the new models were recovered fairly well by using the freeware WinBUGS; the failure to account for such behavior by fitting standard IRT models resulted in overestimation of difficulty parameters on items located toward the end of the test and overestimation of test reliability; and the linearity assumption in performance decline was rather robust. An empirical example is provided to illustrate the applications and the implications of the new class of models.  相似文献   

Does segmenting principle counteract modality principle in instructional animation?     

Jongpil Cheon  Steven Crooks  Sungwon Chung 《British journal of educational technology : journal of the Council for Educational Technology》2014,45(1):56-64

This study investigated the segmenting and modality principles in instructional animation. Two segmentation conditions (active pause vs. passive pause) were presented in combination with two modality conditions (written text vs. spoken text). The results showed that the significant effect was found in relation to segmentation conditions, whereas the modality effect was not found. The groups with embedded questions (ie, active pause) between segments outperformed pause‐only groups (ie, passive pause) on both recall and transfer tests regardless of the mode of text. The findings of the study imply that a stimulus (eg, testing occasion) would be more effective than only pauses between segments.  相似文献   

Mentoring Within the Field of Counseling: A Preliminary Study of Multicultural Perspectives     

Rita Chi-Ying Chung  Fred Bemak  Regine M. Talleyrand 《International journal for the advancement of counseling》2007,29(1):21-32

Although the concept of mentoring is receiving increasing attention in the counseling field, the intersection between multiculturalism and mentoring has not been formally addressed. This article explores mentoring relationships between faculty and students within counselor education from a multicultural perspective. Semi-structured interviews were used to explore African American, Asian American and Latina/o American counselor education graduate students’ perspectives on mentoring. Three similar themes (trust/comfort/honesty; respect; and teacher/student/guide) emerged for all three racial/ethnic groups as important key elements in the mentoring relationship, but with some distinctive culturally relevant variations in emphasis. Also, all three groups to some degree reported that having a mentor who was culturally competent and sensitive was helpful, adding further weight to the view that cultural issues play a role in mentoring relationships. Implications of the findings are discussed.  相似文献

The (mis)use of the Finnish teacher education model: ‘policy-based evidence-making’?     

Jennifer Chung 《Educational research; a review for teachers and all concerned with progress in education》2016,58(2):207-219

Abstract

Background: International achievement studies such as the Programme for International Student Assessment (PISA) have an increasing influence on education policy worldwide. The use of such data can provide a basis for evidence-based policy-making to initiate educational reform. Finland, a high performer in PISA, is often cited as an example of both efficient and equitable education. Finland’s teachers and teacher education have not only garnered much attention for their role in the country’s PISA successes, but have also influenced education policy change in England.

Main argument: This article argues that the Finnish model of teacher education has been borrowed uncritically by UK policy-makers. Finnish and English philosophies of teacher preparation differ greatly, and the borrowing of the Finnish teacher education model does not fit within the teacher training viewpoint of England. The borrowed policies, thus, were decontextualised from the wider values and underpinnings of Finnish education. This piecemeal, ‘pick “n” mix’ approach to education policy reform ignores the fact that educational policies and ‘practices exist in ecological relationships with one another and in whole ecosystems of interrelated practices’. Thus, these borrowed teacher preparation policies will not necessarily lead to the outcomes outlined by policy-makers in the reforms.

Sources of evidence: Two teacher preparation reforms in England, the University Training Schools (outlined in the UK Government’s 2010 Schools White Paper, The Importance of Teaching) and the Master’s in Teaching and Learning (MTL), are used to illustrate the problematic nature of uncritical policy borrowing. This article juxtaposes these policies with the Finnish model of teacher education, a research-based programme where all candidates are required to complete a Master’s degree. The contradictions exposed from this analysis further highlight the divergent practices of teacher preparation in England and Finland, or the disparate ‘ecosystems’. Evidence of educational policy borrowing in other settings is also considered.

Conclusions: Both the MTL and the White Paper reforms overlook the ‘ecosystem’ surrounding Finnish teacher education. The school-based MTL contrasts with the research-based Finnish teachers’ MA. Similarly, the University Training Schools scheme, based on Finnish university-affiliated, teaching practice schools, contrasts heavily with the rest of the White Paper reforms, which contradict the philosophies and ethos behind Finnish teacher education by proposing the move of English teacher preparation away from the universities. The analysis highlights the uncritical eye through which politicians may view international survey results, looking for ‘quick fix’ options instead of utilising academic evidence for investigation on education and education reform.  相似文献   

Quality assurance of joint degree programs from the perspective of quality assurance agencies: experience in East Asia     

Yung-Chi Hou  Martin Ince  Sandy Tsai  Wayne Wang  Vicky Hung  Chung Lin Jiang 《高等教育研究与发展》2016,35(3):473-487

Joint degree programs have gained popularity in East Asia, due to the growth of transnational higher education in the region since 2000. However, the external quality assurance (QA) and accreditation of joint degree programs is a challenge for QA agencies, as it normally involves the engagement of several institutions and multiple national accreditation procedures. The purpose of this study is to explore current QA approaches to joint degree programs in Europe and East Asia from the perspectives of QA agencies. There are four major findings from the study. First, East Asian countries tend to stipulate national regulations for a joint degree program. Second, an external QA mechanism for joint degree programs has not yet been developed in East Asian nations. Third, the adoption of international accreditation as the popular approach for joint degree programs in business fields in Asia raises the serious issue of national jurisdiction over higher education. Fourth, the European Consortium for Education's (ECA) single accreditation mode is highly recommended by QA agencies.  相似文献
