With the introduction of Internet-based education such as online learning and virtual campuses. there are increased interests and demands for electronically delivering educational contents in comparison to the traditional educational methods. Our preilminary study showed that approximately $50\%$ of virtual groups formed online for the scope of collaborative learning encountered harriers that prevented them from forming an effective learning team and making satisfactory progress toward reaching the learning objectives. In this study, we asked the undergraduate students. who were the members of the online learning team, to work on the given discussion topics through the use of emails and threaded discussion boards. Then. we investigated the roles played by two electronic communication medium during the virtual discussion with respect to the learning outcome. We also studied how information was shared amongst the virtual learning team members. The results of our study showed that the email based online learning had the advantage of individualized and friendly information transfer. However. it also caused certain difficulty in exchanging ideas due to the one-sided nature of the email-based communication. On the other hand, the threaded discussion board provided easier information sharing and broadcasting. which enabled active participation by the virtual team members. However. It also had the disadvantage of difficulty in accurate information conveyance and duplication of the posted information. In summary, our study results showed that there was a high correlation between the characteristics of the electronic communication medium and the decision that the online learners made regarding which medium to use. There was a high correlation between the type of the electronic communication medium and the online learners' experiences in using these media.

기존의 인터넷과 컴퓨터 등의 발달로 교육현장에서도 많은 WBI (Web-Based Instruct ion)들이 개발되고 사용되고 있으나 교육사이트의 컨텐츠를 살펴보면 대부분이 행동주의 심리학에 근거를 둔 프로그램 형태를 벗어나지 못하고 있어서 학습자에게 의미있는 학습을 유발시키기 보다는 제시된 정보의 기계적 재생에 그치고 있다는 비판을 받고 있다. 이러한 한계를 극복하는 대안으로는 학습자의 외형적이고 기계적인 면보다는 학습자의 인지활동을 강조하는 인지론적 접근이 필요하다고 본다. 인지심리학의 이러한 측면을 잘 반영하는 학습이론으로서 발견학습 이론을 들 수 있다. 발견학습을 적용시킨 모듈부분은 사용자의 편의에 따라 활용하지 않고 그래프의 탐색이 가능하도록 설계되므로 교사 개개인 수업의 형태에 따라 다양하게 적용할 수 있다. 따라서 온라인과 오프라인상의 모든 현장에서 교수-학습지도에 기절할 것이다.

This study is to design and to develop the educational contents to enhance artificial intelligence literacy. First, we designed artificial intelligence education contents and constructed education programs. The contents are composed of a total of 15 lectures in 8 AI domains. The contents contain the elements of knowledge-skill-attitude, and 5 learning steps. The developed contents were organized in the form of online materials and included simulations and worksheets to directly manipulate and explore the concepts and algorithms of AI. In addition, we provided evaluation questions for each content. To examine the suitability of content, we conducted a validity test for experts. As a result of the content validity test, the overall average was .71 or higher, and the CVI value of the class suitability was .82, indicating a high validity. We are expected to use the contents developed in this study as an effective program to improve AI literacy in university liberal arts education.

The purpose of this assessment was to provide the basic data for setting up education in terms of 'Hand wash' as one of the health plan & education programs for adolescents. The task analyzed the behavior of students regarding hand washing, which were ranged from middle school to high school. The SPSS 18.0 statistical program, frequency-test and cross-analysis were used for data analysis by 2011, 2012 and 2013, which were the recent 3 years, the Korea Youth Risk Behavior Web-based Survey data. In the data, the response of "Never washed" from students before having a meal accounted for 29.4% in 2011, 30.5% in 2012 and 18.5% in 2013, respectively. Unlike other subjects, these facts suggest that this kind of behavior should be considered significant under the assessment. By tracking the trend over three years, some facts were confirmed in that students living in the metropolitan and medium-sized cities were less likely to wash their hands than students in small- sized towns. In terms of gender, female students were less likely to wash their hands than male students. Regarding the type of school, more students in the public middle & high schools had a tendency to respond "Never hand wash" than the students in the special-purpose high schools. Furthermore, as the grade was increased in middle school and high school, students were less likely to wash their hands before meals in school. Therefore, Health promotion and health education for students should be conducted more carefully with more emphasis on this point.

Thepurpose of this study was to provide a basic data health plan & education program for adolescents by examining the recent 3 year Korea Youth Risk Behavior Web-based Survey data obtained in 2013, 2014 and 2015. The data was analyzed with theSPSS 18.0 statistical program using the t-test and cross-analysis. After confirming the drinking habits of teenagers in Korea, the issue was slightly lower in the issue of problem drinking. However, the first time for drinking alcohol was the 2nd grade of middle school(21.5%) and the average alcohol intake was 20 to 29 days(3.8%) and usually consisted ofmore than two bottles (12.2%)s. Also, the method of buying liquor was found to be mainly at convenience stores(32%), and the adolescents werefound not to have been trained for drinking(52%). As a result of comparing the general characteristics of these items, it was found that there was a significant difference between the coeducation type, the high school type, the trace in the residence type, and the 'middle-high level' in terms of the socio-economic level.When comparing the results of the drinking behavior during these three years, the outcome of the trend is still noteworthy, as health education for drinking alcohol is still important, and attention needs to be paid to this problem.

This study reports on the development of a dietary education program for Korean young adults in single-person households. The 7th National Health and Nutrition Survey (2016-2018) was used to compare and analyze the dietary behavior of single-person households and multi-person households, and an online survey was conducted on 350 young adults (age 19-39 years) living in Seoul. According to the analysis, single-person households had higher rates of breakfast and eating out than multi-person households, and significantly lower average intake of energy and nutrients (p<0.05). In particular, in the case of single-person households, the lower the frequency of cooking at home, the higher the rate of breakfast and the higher the frequency of eating out and delivery food (p<0.05). Based on the survey, a dietary education program for young adults single-person households was developed by applying the DESIGN six-step procedure and social cognitive theory as a conceptual model. The first session consisted of the health and economic benefits of home-cooked meals, the second session of the importance of the breakfast and the effect of exercise in life, the third session of the importance of balanced nutrition and the principles of a healthy diet, the fourth session of food safety and storage, and the fifth session of social dining. Each session was composed of a combination of theoretical lectures to motivate 'more making and eating healthy home-cooked meals' and cooking practice for improving behavioral performance.
