According to the online learning environment, learning activities using mobile technology have emerged as a major concern. The features of mobile technology show potential supporting the emergence of learners' agencies in science education. In this study, 22 research literature on mobile activities in science teaching and learning published in Korea from 2011 to April 2020 were selected. First, the framework of Suarez et al. (2018) was revised and the types of mobile activities were categorized and investigated. Second, the emergence of agencies was examined in the context of science teaching and learning. And also, the relevance of mobile activity types ('Access to content', 'Data collection', 'Peer-to-peer communication', 'Contextual support') to support learners' agency dimension ('goals', 'content', 'action', 'strategy', 'reflection', 'monitoring') was analyzed. The first analysis show that science teaching and learning through mobile activities are changing from traditional to student-centered. Through these activities, students become more involved in learning and get the opportunity to become agents of learning. As a result of the second analysis, it has been confirmed that the emergence of learners' agencies has been supported and strengthened through mobile activities. Whereas, it needs to look upon the relationship between learners' agency and mobile activities in the overall context of science class. This consideration led to implications for the use of mobile technology in future science education and the transition to student-centered education.

부산은 자연적 지리적 인문적 조건은 물론 도시적 위상으로 볼 때, 한국 최고의 해양관광지임에 분명하다. 특히 다대포에서 송도와 남항 북항, 광안리, 동백섬, 해운대를 거쳐 미포와 청사포 그리고 송정, 일광에 이르기까지 부산의 해안선은 모두 강력한 배후도시의 인프라를 갖춘 상태이다. 때문에 도시의 첨단 활동과 바닷가에서 할 수 있는 다양한 레저활동이 어우러진 해양관광 1번지로 자리매김하고 있다. 하지만 이러한 외견적인 특성에도 불구하고, 보다 다양한 해양레저를 하기에는 여러 가지 측면에서 미흡한 것도 사실이다. 만일 해상, 해중에서 가능한 다양한 레저활동을 가능하게 해주는 각종 제반시설과 제도가 운영된다면 부산은 진정한 의미에서 입체적인 해양관광수도가 될 것이다. 이러한 맥락에서 부산에 존재하는 수십 개의 무인도서는 청정한 해양생태환경 속에서 해양레저활동을 향유할 수 있도록 해주는 천연의 자원이 된다.

The purpose of this study is to identify the effects of entrepreneurship experience and education on entrepreneurship intention, and to test the moderating effect of gender on these relationships. To test the hypothesis, we used GETR(Global Entrepreneurship Trend Report) data that was collected by Korea Entrepreneurship Foundation and was consisted of 40,388 data collected from 2,000 people in 20 countries. First, entrepreneurship experience and entrepreneurship education have significant influence on entrepreneurship intention. Second, gender moderating effects on these relationships were found to have a significant effect on the relationship between entrepreneurship education and entrepreneurship intention. Specifically, the positive effect of entrepreneurship education on entrepreneurial intention was found to be stronger for women than for men. Finally, the analysis of the three-way interaction effect of the social protection confirmed that the positive relationship between entrepreneurial experience and entrepreneurial intention was stronger for women than for men, and this effect was found to be higher in the high social protection group. In other words, women with entrepreneurial experience are more likely to increase their entrepreneurial intentions when they are more aware of social protection than men.

사람들은 인터넷을 통해 이메일, 커뮤니케이션, 쇼핑 등 다양한 활동을 즐기고 있다. 인터넷을 통해 의료정보를 접하게 되는 것도 이런 맥락에서 하나의 분야일 뿐이다. 이미 생활의 중요한 축이 되어버린 인터넷이 제공하는 정보 그 중에서도 의료 서비스나 신의료기술 등에 관련된 정보를 어떻게 활용하는 것이 좋을지 생각해 보자.

30년대 후반 이후 민족해방통일전선의 이론적 맥락과 그 구체적 활동을 세세히 추적하고 있는 이 책에서 강교수는, 이념적 노선에 있어서는 상대적으로 좌파를 대표하지만 이들의 통일전선의 궁극적 성격은 계급노선이 아닌 민족노선으로 파악해야 한다고 주장한다.

The purpose of this study is to review how to introduce a division algorithm in mathematics textbooks which were applied 2009 revised curriculum. As a result, the textbooks do not introduce the algorithm in the context of division by equal part. The standardized division algorithm was introduced apart from the stepwise division algorithms and there is no explanation in between them. And there is a lack connectivity between activities and algorithms. This study is expected to help new curriculum and textbook to introduce division algorithm in proper way.

This study aimed to derive pedagogical implications by comparing and analyzing how the concept of pi is taught in 10 different elementary mathematics textbooks, which are scheduled to be applied from 2023. We developed a textbook analysis framework by previous studies on the concept of pi and the teaching of pi, and analyzed in terms of three instructional elements (i.e. inferring conceptsof pi, understanding properties of pi, and applying relationships). We derived the need to emphasize various contexts for estimation of pi, presentation of problem situations that provide motivation to actually measure diameters and circumferences, providing an opportunity to explore the properties of measurement, and an experience the flexibility of selecting an approximate value of pi. Based on the above conclusions and pedagogical implications through the research results., we suggested ways to teach the concept of pi in elementary mathematics and improvement points for developing textbooks focusing on the context of introduction of pi and the use of technological tools.

This study investigated the differences in time use patterns and psychological states across daily activity contexts and interpersonal contexts, depending on the levels of school maladjustment among elementary school students. Using the Experience Sampling Method (ESM), 107 elementary school 6th grade students' daily time use patterns and psychological states across daily contexts were measured six times a day over a period of 4 days. Using the school maladjustment scale, an internal problem based school maladjusted group and an external problem based school maladjusted group were identified and selected. The daily time use patterns and psychological states of both school maladjusted groups were compared to those of the adjusted groups. The principle findings are as follows: first, the school maladjusted group students' daily time use patterns across daily activity contexts or interpersonal contexts did not differ from those of the students from the school adjusted group. Second, the school maladjusted group students experienced more negative emotions, lower concentration levels, and lower motivation levels across daily contexts than the school adjusted group students. These differences in motivation between the external problem school maladjusted group and adjusted group, however, were greater in the schoolwork context compared to the other daily activity contexts. The findings were discussed in the contexts of the daily experiences of child school maladjustment.

There have been raised the question that students have been of no interst in mathematcs and incompetent for solving real world problem because students have been recognized mathematcs as abstract knowldege. We research whether students' modeles developed in modeling activity can mediate between concrete and abstract. The analysis of our case study revealed that students' modeles aren't decontextualized abstraction but is located in situated abstraction that is a network connecting between concrete and abstract. Thus, these modeles are a tool mediating between concrete and abstract. Also, students' modeling activities can provide students with the opportunity of being competent for solving real world problem.

The purpose of this study is to find out whether the current mathematics textbooks are structured so as to cultivate students' statistical literacy. To do this, we analyzed the problems of the statistics units of 9 kinds of middle school 3rd grade mathematics textbook according to 2009 revised mathematics curriculum based on four types of context and statistical problem solving process. As a result of the analysis, among the four types of context, the problems that correspond to the type of personal context was the highest in 67% and among statistical problem solving process, the data analysis process was the highest in 72.85%. According to the results of this study, it is necessary to include the problems that can recognize the necessity of statistics through the use of various contexts and that can develop the statistical literacy through the activities that from the process of collecting data to guessing reasonable conclusions from the presented data.
