정동빈,Jeong, Dong Bin 한국데이터정보과학회 2014 한국데이터정보과학회지 Vol.25 No.6

국내 28개 국공립대학교를 대상으로 대학정보공시제에 근거하여 제시된 교육지표 중 연구성과에 관련된 4개의 양적평가 우량성속성 (1인당 연구비 수혜금액, 1인당 연구재단등재지 (KCI) 실적, 1인당 SCI/SCOUP급 실적, 1인당 저역서 실적)에 대해, 유사한 속성을 지닌 대학들을 유사성있는 군집끼리 분류 및 세분화하고 다차원 공간상에 시각적으로 배치시켰다. 이를 통해서 국내 28개 국공립대학은 4개 군집으로 유형화가 가능하며, 각 군집간 또는 군집내에 속한 대학들 간의 유형 및 특성을 평가할 수 있다. Based on the 4 principal research-performance criteria in 28 national universities in Korea, both cluster analysis and multidimensional scaling are performed in this paper. We can classify and/or specialize the initially unknown groups into a group of relatively homogeneous universities and then create new groupings without any preconceived notion of what clusters may arise. Furthermore, the level of similarity of individual universities can be visualized on the multidimensional space so that each university is then assigned coordinates in each of the 2 dimensions. Both types and characteristics of each university can be relatively evaluated and be practically exploited for the policy of the university authority through these results.

정동빈,Jeong, Dong Bin 한국데이터정보과학회 2015 한국데이터정보과학회지 Vol.26 No.4

본 연구에서 국내 13개 업종과 16개 행정구역을 대상으로 전자상거래 구매동기와 관련된 다섯 개의 양적평가속성 (거래과정단순화, 구매비용절감, 공급자와 직접접촉, 업무추진속도향상, 기타)에 대해, 유사한 속성을 지닌 업종/행정구역들을 유사성 있는 군집끼리 분류 및 세분화하고 다차원 공간상에 시각적으로 배치시켰다. 정보화통계조사 (국가통계포털, www.kosis.kr)의 일환으로 전자상거래 경험이 있는 사업체를 대상으로 자료를 조사하였다. 구매동기 평가속성을 중심으로 유사성이 강한 업종과 행정구역을 분류한 결과 각각 4개와 2개로 유형화가 가능함을 알 수 있었다. 더 나아가 다차원 척도법을 사용하여 각 군집에 속한 업종 및 행정구역의 포지셔닝을 실시한 결과, 구매과정단순화, 구매비용절감 및 공급자와 직접접촉 속성에 대해서, 업종의 도 소매업, 기타 및 제조업이, 행정구역의 서울과 경기가 우위에, 제주는 가장 열세한 위치에 놓여있다. 반면에 업무추진속도향상과 기타속성에 대해서, 업종의 기타와 단체수리 기타 개인서비스업이, 행정구역의 충북과 경남이 각각 우위에 있으며, 도 소매업, 숙박 음식점업과 대구 및 경기는 열등한 점수를 갖는 것을 알 수 있다. Thirteen types of business and sixteen administrative districts in Korea are categorized and segmented based on their similarities and visually plotted on multidimensional space. The similarities are determined by five characteristics of quantitative evaluation (simplified process of trading, reduced price, direct contact with supplier, faster process of trading, et cetera). Hence, domestic types of business and administrative districts can be categorized into certain clusters. Also, forms and characteristics of types of business and administrative districts can be evaluated between and within the clusters.

수준별 조기영어 몰입수업에서 형태초점 교수전략 효과 연구

정동빈(Jeong Dong-Bin),김지숙(Ghymn Jisook) 팬코리아영어교육학회(구 영남영어교육학회) 2008 영어교육연구 Vol.20 No.3

The purpose of the present study is to analyze the effect of differentiated groups learning in early elementary English immersion education. 34 elementary school students participated in the research. They were divided into two groups such as a below-level and an on-level. Subjects’ data samples were collected from the 1st graders of Seoul M Elementary School. This study used both class observation and recording. In the course of research, a focus-on-form teaching method was applied to obtain as much uptake as subjects could get in accordance to teachers‘ corrective feedback strategies(eg. Q/S(Question/Student) strategy) in the differentiated groups. This study suggests that differentiated teaching for the 1st graders in the English immersion classroom is insignificant because students are believed to possess LAD even in L2 stage. This study also suggests that teachers should consider the gap in differentiated groups, not as a variation in learning competence, but as the need to provide diversified teaching strategies, methods and lesson plans, by recognizing the difference in the students’ previous exposure to English.

The purpose of this study was to examine the effects of culture teaching and using web sites as a method of culture teaching in college English education. To achieve these purposes, a web-based culture teaching-learning model was developed and applied in English classes. Then, the effects were compared with those of a culture teaching method which were based on the traditional verbal explanation. As the tools for this study, two test sheets were used to measure language proficiency and American cultural knowledge. Focusing on the study results, the conclusions were summed up as follows: First, for enhancing the American cultural knowledge, using the web was found to be more effective than traditional verbal explanations. Second, for English language enhancement through web-based culture teaching, it is necessary to do it for each level of English proficiency or develop web sites which fit well with students' interests or levels.

정동빈(Jeong Dong Bin) 한국경영교육학회 2012 한국경영교육학회 학술발표대회논문집 Vol.2012 No.12

본 연구는 학생 수 1만 명 미만의 국내 14개 국립대학교를 대상으로 교육과학기술부에서 제시한 주요 8개의 교육지표를 사용하여 다차원척도법을 분석하였다. 이 분석법은 각 대학들 사이의 유사성과 비유사성을 평가하는데 사용될 수 있는 교육지표에 근거하여 각 지표에 대해 각 대학을 다차원 공간상에 시각적으로 표현할 수 있다. 더 나아가 다차원척도법과 함께 대학들간의 상이성 거리행렬을 사용함으로 써 각 대학간의 유사성과 상이성을 분석할 수 있으며, 8개의 주요 교육지표 중 어느 지표에 더 주안점을 두고 정책을 세워야 할지를 예상할 수 있다. The analysis of multidimensional scaling (MDS) performed in this paper is based on the eight common education criteria in fourteen national universities in Korea. All national universities considered here will be ones less than 10,000 students and the applied criteria are derived from those of ministry of Education Science and Technology in Korea.The MDS statistical technique exploited in this paper can obtain visual representation for exploring the pattern of proximities among 14 universities. Furthermore, similarities and dissimilarities among universities can be analyzed by using distance matrix along with MDS and thus which criterion is supposed to be focused on among eight educational criteria for each university. Based on these results university authority will carry out policy or perform policy switch to the competitive direction.

정동빈(Jeong Dong Bin) 한국경영교육학회 2014 한국경영교육학회 학술발표대회논문집 Vol.2014 No.6

본 연구는 국내 28개 국공립대학교를 대상으로 대학정보공시제에 근거하여 제시한 교육지표(교육여건부문과 교육성과 및 학사관리부문)에 관련된 14개의 평가항목변수를 사용하여 군집분석을 실시하였다. 군집분석기법을 사용하여 각 대학들 사이의 유사성과 비유사성의 정도를 측정하여 대학들을 가까운 순서대로 군집화한다. 또한 두 부문에 해당하는 각각의 7개 평가항목에 나타나는 군집들의 특징과 성격을 파악할 수 있다. 교육지표에 대한 분석결과, 국내 국공립대학은 5개 군집으로 유형화 가능하며 각 군집유형간에 현저한 특징을 발견할 수 있다. Cluster analysis performed in this paper is based on the 14 common education criteria in 28 national universities in Korea. We maximize the similarity of universities within each cluster while maximizing the dissimilarity between groups that are initially unknown by using cluster analysis and then create new groupings without any preconceived notion of what clusters may arise. In this case, the cluster can be a group of relatively homogeneous universities base on the education indices so that the comparative evaluation can be made between groups, to which each university belong. Based on these results university authority will carry out policy or perform policy switch to the competitive direction.
