用HMO理论解释卡宾的电子结构与立体结构及其反应     

蒋笃孝  宋龄瑛  邝代治 《衡阳师范学院学报》1993,(3)

卡宾的基态有单线态和三线态两种状态。本文用HMO法的近似解说明了卡宾是以单线基态还是以三线基态存在的原因,同时也比较满意地解释了卡宾弯曲空间结构的特点,以及环状共轭卡宾的亲核或亲电反应性质。本文认为,卡宾中心碳原子是SP~2杂化。卡宾的基态是单线态还是三线态取决于卡宾中心碳原子的非键P轨道与相邻原子的P轨道的相互作用以及P电子的数目。  相似文献   

The use of educational comics in learning anatomy among multiple student groups          下载免费PDF全文

Jiyoon Kim  Min Suk Chung  Hae Gwon Jang  Beom Sun Chung 《Anatomical sciences education》2017,10(1):79-86

Understanding basic human anatomy can be beneficial for all students, regardless of when, or if, they will later undertake a formal course in the subject. For students who are preparing to undertake a formal anatomy course, educational comics on basic anatomy can serve as a concise and approachable review of the material. For other students, these comics can serve as a helpful and fun introduction to the human body. The objective of the comics in this study was to promote an understanding of fundamental human anatomy through self‐learning among students. Based on the authors' previous teaching experience, these anatomy comics were produced in a simple, direct style. The comics were titled after the two main characters, “Anna” (a girl) and “Tommy” (a boy). These comics were then presented to groups of elementary school students, high school students, premedical students, and medical students to assess the comics' ability to enhance student interest and comprehension of basic anatomy. Quiz scores among high school students and premedical students were significantly higher among participants who read the educational comics, indicating a deeper comprehension of the subject. Among medical students, close reading of the comics was associated with improved course grades. These educational anatomy comics may be helpful tools to enrich a broad spectrum of different students in learning basic human anatomy.

Exploring game experiences and game leadership in massively multiplayer online role‐playing games     

YeiBeech Jang  SeoungHo Ryu 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(4):616-623

This study explored the in‐game experiences of massively multiplayer online role‐playing game (MMORPG) players focusing on game leadership and offline leadership. MMORPGs have enormous potential to provide gameplayers with rich social experiences through various interactions along with social activities such as joining a game community, team play and others. In this study, a total of 808 Korean online gameplayers participated in an online survey. Amongst them, 300 MMORPG players were used as the final sample group. The results showed that joining a game community and playing in teams may help players build their leadership experience in games. The findings also suggest that there is a significant positive relationship between in‐game leadership and offline leadership. However, there were no significant differences in gender regarding in‐game and offline leadership. This study suggests that MMORPGs offer a useful place where people can grow their leadership skills and potentially transfer them into the real world.  相似文献

"Digit anatomy": a new technique for learning anatomy using motor memory     

Oh CS  Won HS  Kim KJ  Jang DS 《Anatomical sciences education》2011,4(3):132-141

Gestural motions of the hands and fingers are powerful tools for expressing meanings and concepts, and the nervous system has the capacity to retain multiple long-term motor memories, especially including movements of the hands. We developed many sets of successive movements of both hands, referred to as "digit anatomy," and made students practice the movements which express (1) the aortic arch, subclavian, and thoracoacromial arteries and their branches, (2) the celiac trunk, superior mesenteric artery and their branches, and formation of the portal vein, (3) the heart and the coronary arteries, and (4) the brachial, lumbar, and sacral plexuses. A feedback survey showed that digit anatomy was helpful for the students not only in memorizing anatomical structures but also in understanding their functions. Out of 40 students, 34 of them who learned anatomy with the help of digit anatomy were "very satisfied" or "generally satisfied" with this new teaching method. Digit anatomy that was used to express the aortic arch, subclavian, and thoracoacromial arteries and their branches was more helpful than those representing other structures. Although the movements of digit anatomy are expected to be remembered longer than the exact meaning of each movement, invoking the motor memory of the movement may help to make relearning of the same information easier and faster in the future.  相似文献   

Pedagogy and Foreignness     

Soo Bin Jang 《Multicultural Perspectives》2018,20(2):117-121

Based on my reflections on “being a foreigner,” I explore the boundaries of citizenship education in this essay. I use my foreign identity to articulate how social justice education can perpetuate closed-mindedness in classrooms by moving too quickly to student activism. I situate my experiences and reflections on being a foreigner within previous conversations about notions of certainty and indoctrination in the field of education philosophy, and I make an argument to create a safe intellectual space for my students. Creating such space is not neglecting moral responsibility or perpetuating privilege but actually navigating through the binary between “us” and “them.”  相似文献   

Comparing the standards of one metabolic equivalent of task in accurately estimating physical activity energy expenditure based on acceleration

The purpose of the study is to analyse how the standard of resting metabolic rate (RMR) affects estimation of the metabolic equivalent of task (MET) using an accelerometer. In order to investigate the effect on estimation according to intensity of activity, comparisons were conducted between the 3.5 ml O₂ · kg^?1 · min^?1 and individually measured resting VO₂ as the standard of 1 MET. MET was estimated by linear regression equations that were derived through five-fold cross-validation using 2 types of MET values and accelerations; the accuracy of estimation was analysed through cross-validation, Bland and Altman plot, and one-way ANOVA test. There were no significant differences in the RMS error after cross-validation. However, the individual RMR-based estimations had as many as 0.5 METs of mean difference in modified Bland and Altman plots than RMR of 3.5 ml O₂ · kg^?1 · min^?1. Finally, the results of an ANOVA test indicated that the individual RMR-based estimations had less significant differences between the reference and estimated values at each intensity of activity. In conclusion, the RMR standard is a factor that affects accurate estimation of METs by acceleration; therefore, RMR requires individual specification when it is used for estimation of METs using an accelerometer.  相似文献
