晚自修上的停电事件     

KK 《初中生学习》2006,(9)

一节很普通的晚自修,因为两次停电事件而变得与众｛不同,但我心里仍然暗存着一种遐想:再来一次,好吗?在一节很普通的晚自修上,我正在看最有益的小说——历史教科书。突然,眼前一片漆黑,所有的光芒浓缩成一个小点瞬间消失,同时我们还听见了班里只用来收看C CTV新闻联播的电视机关机时发出的轻而有力的“卟”声——停电了!顷刻间,惊慌中又夹杂着幸灾乐祸的“噢”异口同声地蹦出来。伸手不见五指,我感到一股恐惧涌上心头,然而这时,一些同学的脸却突然变亮。聪明的他们在第一时间光明正大地拿出手机,查看信息也好,玩游戏也好,毕竟都为我们带来…  相似文献   

Exploring high school students' and teachers' preferences toward the constructivist Internet‐based learning environments in Taiwan     

Min‐Hsien Lee & Chin‐Chung Tsai 《Educational studies》2005,31(2):149-167

This paper explores high school students' and teachers' preferences towards constructivist Internet‐based learning environments. The study proposes a framework, including two dimensions and five aspects, to illustrate the features of the Internet‐based learning environments. Based upon this framework, the Constructivist Internet‐based learning environment survey improvement (CILESI) was developed, which includes the scales of ease of use, multiple sources, student negotiation, reflective thinking, critical judgement and epistemological awareness. Questionnaire responses gathered from 630 high school students in Taiwan suggested that the CILESI showed adequate reliability in assessing students' preferences. Male students placed more emphasis on the student negotiation, critical judgement and epistemological awareness enhanced by the Internet‐based learning environments than female students did. In addition, the teachers of the sampled students (n?=?78) were also surveyed by CILESI. The teachers tended to express stronger preferences on the ease of use of the Internet‐based learning environments than did their students. However, students, when compared with their teachers, seemed to express more preferences towards the features of student negotiation, reflective thinking, critical judgement and epistemological awareness of Internet‐based learning environments.  相似文献

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
