Building key competencies into an environmental education curriculum using a modified Delphi approach in South Korea     

Eunjung Seo  Jaemyong Ryu  Seyoung Hwang 《Environmental Education Research》2020,26(6):890-914

Abstract

This study adopted the modified Delphi method to build key competence indicators for the course subject ‘Environment’ in the secondary school curriculum in South Korea. 15 Delphi panelists participated, and were provided a three-stage questionnaire survey. The findings classified eight secondary school ‘environment’ curriculum key competencies into three domains: intellect-oriented, personality-oriented, and relationship-oriented. The intellect-oriented domain includes ‘critical-thinking ability,’ ‘creativity,’ and ‘problem-solving ability’; the personality-oriented domain includes ‘autonomy,’ ‘ability to reflect,’ and ‘environmental sensitivity’; and the relationship-oriented domain includes ‘communication ability’ and ‘ability to manage conflicts.’ These environmental competencies were utilized to revise the current environmental education curriculum as part of the 2015 revision of the National Curriculum and set the key competencies for environment classes. The paper concludes with the significance of developments in theorizing and implementing environmental education curriculums in Korea and abroad.  相似文献   

Crowdsourcing civility: A natural experiment examining the effects of distributed moderation in online forums     

Cliff Lampe  Paul Zube  Jusil Lee  Chul Hyun Park  Erik Johnston 《Government Information Quarterly》2014

Participation in discussions about the public interest can be enhanced by technology, but can also create an environment in which participants are overwhelmed by the quantity, quality, and diversity of information and arguments. Political participation is at a greater disadvantage than non-political activities in that participants from different parties already start out with established differences, which requires them to reach some form of common ground before progress can be made. Those seeking authentic deliberation are discouraged to participate when confronted with uncivil and inflammatory rhetoric. These issues are often exacerbated in online discussions, where lack of identity cues and low barriers to entry can lead to heightened incivility between participants, often labeled as “flaming” and “trolling”. This paper explores the extent to which moderator systems, tools online discussion forums use to manage contributions, can reduce information overload and encourage civil conversations in virtual discussion spaces. Using the popular website Slashdot as an example of sound moderation in a public discourse setting, we found that users move toward consensus about which and how comments deserve to be moderated. Using these findings, we explore how transferable these systems are for participation in public matters specifically to the unique attributes of political discussion. Slashdot's political forum provides a comparison group that allowed us to find quantitative and qualitative differences in political posting, comments, and moderation. Our results show that large scale, civil participation is possible with a distributed moderation system that enables regularly lively debates to be conducted positively because the system provides tools for people to enforce norms of civility.  相似文献   

A new perspective on in vitro assessment method for evaluating quantum dot toxicity by using microfluidics technology     

Sanjeev Kumar Mahto  Tae Hyun Yoon    Seog Woo Rhee 《Biomicrofluidics》2010,4(3)

In this study, we demonstrate a new perspective on in vitro assessment method for evaluating quantum dot (QD) toxicity by using microfluidics technology. A new biomimetic approach, based on the flow exposure condition, was applied in order to characterize the cytotoxic potential of QD. In addition, the outcomes obtained from the flow exposure condition were compared to those of the static exposure condition. An in vitro cell array system was established that used an integrated multicompartmented microfluidic device to develop a sensitive flow exposure condition. QDs modified with cetyltrimethyl ammonium bromide∕trioctylphosphine oxide were used for the cytotoxicity assessment. The results suggested noticeable differences in the number of detached and deformed cells and the viability percentages between two different exposure conditions. The intracellular production of reactive oxygen species and release of cadmium were found to be the possible causes of QD-induced cytotoxicity, irrespective of the types of exposure condition. In contrast to the static exposure, the flow exposure apparently avoided the gravitational settling of particles and probably assisted in the homogeneous distribution of nanoparticles in the culture medium during exposure time. Moreover, the flow exposure condition resembled in vivo physiological conditions very closely, and thus, the flow exposure condition can offer potential advantages for nanotoxicity research.  相似文献   

Current and potential use of fresh frozen cadaver in surgical training and anatomical education     

Yong Keun Song  Dong Hyun Jo 《Anatomical sciences education》2022,15(5):957-969

As surgical procedures continue to be more complex, the need for more effective training in anatomy has increased. The study of anatomy plays a significant role in the understanding of the human body as well as in basic and advanced clinical training. Among the different cadaver models, fresh frozen cadavers (FFCs) are known for their realistic tissue quality. The purpose of this article was to review and summarize the preparation procedures for and reported cases involving FFCs. PubMed, Scopus, Medline, and Web of Science were searched for relevant studies. The preparation procedures were divided into five steps: washing, irrigation, freezing, defrosting, and arterial infusion. Not all steps were reported to be mandatory, but omitting one or more could result in a loss of quality. FFCs were reported to be used for various purposes: undergraduate education, general surgery training, vascular surgery training, minimal access surgery (laparoscopic surgery) training, and microsurgery training. In all categories, expert opinions and statistical analyses indicated successful outcomes. The reasons for high satisfaction with FFCs included realistic texture, capability of reenacting actual operations, and accuracy of anatomical locations. The results also revealed the importance and advantages of the dissection courses in surgical training. Since the direct comparison between cadaver models is insufficient, future studies regarding this topic are deemed necessary. In addition, it would be advantageous to develop methods to improve FFC quality, or ideas to optimize this model for certain purposes.  相似文献
