This study investigated the influences of Vee diagram and regulative metacognitive learning strategies upon 6th-graders' achievement, difficulty toward science lesson, self-efficacy, and learning approach. The Vee diagram and regulative metacognitive learning strategies were modified in a pilot study. Before instruction, an achievement test was administered, and its score was used as a blocking variable. A previous science grade was used as a covariate for post-achievement. Tests of difficulty toward science lesson, self-efficacy, and learning approach were also administered, and the test scores were used as covariates. After instruction, a researcher-made achievement test and post-tests of the above variables were administrated. Two-way ANCOVA results revealed that although there were no significant differences in the achievement test scores, the application subtest scores of the two treatment groups were significantly higher than those of the control group. There were no significant differences in the difficulty toward science lesson and learning approach, but self-efficacy scores for the students with Vee diagram and regulative metacognitive learning strategies were significantly higher than those of the other groups. The perceptions of the students using Vee diagram were also analyzed.

의미 모호성 해소는 문맥상의 한 단어의 올바른 의미를 밝히는 것으로, 대부분의 자연언어처리 응용에서 가장 중요한 문제 중 하나이다. 말뭉치로부터 얻어진 예제로부터 의미 모호성 해소 방법을 학습하기 위해서는 답이 알려져 있는 대량의 학습 예제가 필요하지만, 답이 알려져 있는 예제를 구하는 일은 사람의 간섭을 필요로 하므로 매우 비싼 작업이다. 본 논문에서는 답이 알려져 있는 학습 예제로 어느 정도 학습한 수, 답이 알려져 있지 않은 예제로 학습을 보충하는 방법을 통해 사람의 간섭을 최소화하였다. 결정트리 학습을 통한 한국어 명사에 대한 의미 결정 실험 결과, 본 논문에서 제안한 방법은 가장 많은 분포를 보이는 의미를 선택하는 경우보다 평균적으로 33.6%의 성능 향상을 보이며, 이는 전체 학습 예제의 답이 모두 알려져 있는 경우와 거의 비슷한 결과이다. 따라서, 한국어와 같이 신뢰할 만한 의미 부착 말뭉치가 없는 경우에 본 논문에서 제시된 방법은 매우 효율적이다.

IT강국의 선진한국으로 도약하고 있는 우리나라는 현재 웹을 이용한 학습을 넘어 휴대인터넷 (WiBro)과 UMPC (Ultra Mobile PC)를 비롯한 모바일 환경에서의 학습도 활발해지고 있다. 더불어 요즘 세대의 학생들은 일방적인 주입식 교육 보다는 상호작용하며 즉각적인 피드백을 받을 수 있는 게임적 요소에 큰 관심을 보인다. 본 연구에서는 학습자의 특성을 고려하여 모바일 학습에서 학습자의 학습동기를 유발, 지속시키기 위한 방안으로써 Keller의 동기 유발 이론에 기초한 게임 전략을 접목시킨 새로운 동기 모형을 제시하고자 한다. 본 동기 모형의 특징은 다음과 같다. 첫째, 주제에 맞는 장르 및 형태를 기획분석 단계에서부터 결정하여 개발 효율성을 추구하였다. 둘째, 에듀테인먼트 요소를 콘덴츠 제작 절차에 삽입함으로써 학습활동에 대한 능동적 반응과 흥미를 얻도록 하였다. 셋째, 체계적인 모바일 교육용 게임 설계를 위해 게임 시놉시스, 시나리오 작성 단계를 삽입하였으며 궁극적으로는 모바일 동기전략과의 통합을 추구하였다. 넷째, 개발된 콘텐츠를 수업안에 바로 적용시킴으로써 자연스러운 수업이 될 수 있도록 구성하였다.

일본의 국립공원정책을 참고하고 본 연구의 결과를 통하여 세 가지 측면에서 나타나는 문제점에 대한 개선방안을 제시해보면 첫 번째 보전적인 측면은 용도지구 및 공원구역의 전면적인 재조정, 두 번째 이용적인 측면은 교통, 주차시설의 확충 및 도로체계의 재조정, 자연학습공간의 설치 및 환경교육(해설) 프로그램의 개발, 세 번째 관리적인 측면으로 도립공원 재원확보, 관리 인력의 증원 및 전문 인력의 배치 등을 들 수 있다. 나아가 공원구역의 전면적인 재조정으로부터 지역주민들의 의견수렴을 충분히 거친 후 자연보존지구에 대한 보존대책을 수립한 다음 도립공원 해제방안도 적극적으로 고려하여야 할 것이다. 그러나 보다 중요한 것은 일본의 환경정책을 예로 들었듯이, 환경보전적 측면에서 오히려 역행하고 있는 현행 우리나라 자연공원 정책이 전환되어야 한다는 것이다. 이에 환경보전적 측면을 중시한 자연공원법의 조속한 개정과 생물다양성을 관점으로 한 자연공원정책이 전개되어야 할 것이다.

In this study, the effects of grouping by extraversion and introversion in POE learning applied to elementary science class on students' achievement, the perception of learning environment and the attitude toward science instruction were investigated. Ninety-five 5th graders were assigned to the control group and the experimental groups, and taught about acid and base for 9 class hours. In the experimental groups, the homogeneous small group was composed of four introverts or four extroverts, and the heterogeneous small group was composed of two introverts and two extroverts. Two-way ANCOVA results revealed that the homogeneous group performed better than the control group in the application subtest of the achievement test. Significant difference in learning difficulty was found between the heterogeneous group and the control group. In the attitude toward science class, significant interaction effect was found between the instruction and the extraversion/introversion.

Big data analysis for disaster have been recently started especially to text data such as social media. Social data usually supports for the final two stages of disaster management, which consists of four stages: prevention, preparation, response and recovery. Otherwise, big data analysis for meteorologic data can contribute to the prevention and preparation. This motivated us to review big data technologies dealing with non-text data rather than text in natural disaster area. To this end, we first explain the main keywords, big data, data mining and machine learning in sec. 2. Then we introduce the state-of-the-art machine learning techniques in meteorology-related field sec. 3. We show how the traditional machine learning techniques have been adapted for climatic data by taking into account the domain specificity. The application of these techniques in natural disaster response are then introduced (sec. 4), and we finally conclude with several future research directions.

This study was conducted to present an alternative instructional model through natural experience activities by developing a natural experience activity program that can learn and feel how to recognize and act on nature based on flow learning. In order to achieve the purpose of the study, a nature experience program, which consists of four stages of meeting nature, exploring nature, playing with nature and sharing emotions, was developed based on the main procedures of each stage of the ADDlE instructional design model. Through the research process, activities and precautions for each stage of the nature experience activity program were presented, and major educational implications were discussed based on the developed program. The nature experience program developed through the study can provide teachers with a basic direction for nature experience activities along with changing their perception of how to do nature experience activities, and infants are expected to become learners who freely feel, experience nature and make up their own knowledge through the nature experience program.

The study, executed with Hallasan National Park, which deserves to be a typical ecotourism destination, aims to provide basic information on park management for early establishment of ecotourism in a national park by assessing its visitors' behavior and satisfaction with a nature trail established as a series of an environmental interpretation program. The questionnaire survey was conducted at Eorimok Square in the weekday and on the weekend for two months of August and September in 2006, and finally 144 valid samples were used for the analysis. As a result of the research, it revealed that the demographic characteristics of the visitors to Hallasan National Park tended to coincide with those of the visitors to other national parks In Korea. On the whole, it showed their low recognition level of nature trails built up in national parks and less experience in using them. However, the visitors' satisfaction level and intention of re-visit, and recommendation to others were comparatively higher after actually using the nature trail at the site of Hallasan National Park, which hints at the possibility of national parks' much weightier role as the ground for ecology education and the functional expansion of the environmental interpretation-related facilities and programs. As for the attributes having effects on users' satisfaction with a nature trail, substantial aspects such as accessibility, safety, uniqueness and interest in environmental interpretation, and educational quality as well as physical facility management were revealed to have equal effects on users' satisfaction level, so there still remain a lot of pending issues over the reality of national parks in the initial stage of ecotourism staying at the level of the introduction and establishment of the facilities for environmental interpretation. This research had surveyed visitors to Hallasan National Park and limited to the nature trail only. For more systematic and practical ecological management of a national park, the in-depth understanding of the attributes affecting satisfaction of ecotourists, including nature trails and other environmental interpretation programs, and more sophisticated measuring tools are needed.

We designed and applied team project based learning for effective computer programming education and analyzed the effect on learning effect. Throughout simplified traditional theories and practices, teamed up with random lottery, divided role & responsibility, and conducted problem solving projects in a competitive way for a given task. When after completion of the course, we conducted questionnaires on learners in order to grasp the influence factors on the learning effect. As a result of the structural equation model analysis, it was shown that Team Project had a direct effect on the learning effect. The learning effect based on the relationships among the factors derived through exploratory factor analysis. Based on this analysis, we propose a more effective computer programming education way.
