The aim of the present study is twofold. One is to confirm a hypothesis that a student's rate concept influences her conceiving change of a function in the view of rate of change and the other is to build up foundations for understanding the transition process from her rate concept to the concept of rate of change when she investigates the change of concentration as an intensive quantity. We explored how three participating high school students recognized and expressed change of given functions by using their rate concept as a conceptual tool. The result indicates that a change in students' rate concept might have an effect on understanding how function values change in term of rate of change. We also expect that it could be a catalyst for further research for clarifying the relationship between students' rate concept and their development of a concept of rate of change as a foundation for learning calculus.

The purpose of this study is to develop a mobile-based math learning application and explore its application. In order to develop a learning application, the present study included literature review on math education involving mobile learning, investigation of literature related to mathematics education conducted in a digital environment, and method of use and implementation environment of existing math learning applications by type. Based on these preliminary investigation and analysis, an android version application, 'Mathematics Classroom for Middle School 3rd Graders' was developed. This application can be used for learning units such as Quadratic Functions and Graphs, Representative Value, and Variance and Standard Deviation. For the unit on Quadratic Functions and Graphs, the application was constructed so that students can draw various graphs by using the graphic mode and discuss their work with other students in the chatting room. For the unit on Representative Value, the application was constructed with the mathematical concept of representative value explained through animation along with activities of grouping data acquired after playing archery games by points or arranging them according to size so that students can study when and how to use median value, mode, and average. The application for Variance and Standard Deviation unit was also constructed in a way that allowed students to study the concept of variance and standard deviation and solve the problems on their own. The results of this study can be used as teaching & learning materials customized for individual student in math classes and will provide anyone the opportunity to engage in an interesting self-directed learning of math at anytime. Developed in the format of real life study, the application will contribute to helping students develop a positive attitude about math.

The Korean government has administered the 'AMPQ-II' to all middle school students to prevent psychological problems and make immediate interventions when necessary. On the other hand, there has been a paucity of studies of the effectiveness of this governmental policy, or the factors influencing the effectiveness of the intervention. Using the data from 48 counselees from two middle schools, the present study examined the effectiveness of the intervention programs, and whether the counselor's characteristics and the number of counseling sessions might matter in the effect. The results suggested that most students reported improvements after the interventions. The intervention effect was less pronounced when the counselors had governmental certification. The number of counseling sessions was not a significant factor for predicting the effectiveness of the interventions. Interpretations of the present study should be made cautiously because of the small sample size. The present results, however, suggest that efforts to improve the quality of the counseling teachers are necessary. In addition, increasing the number of counseling sessions is not necessarily effective.

One of the most controversial issues in contemporary research of creativity, whether a person"s creativity is domain-specific or domain-general, was investigated with 109 second grade children in the present study. The purposes of this study sere to empirically examine (1) the relationships among children's creative performances measured by three product-based assessments (story-telling, collage-making, and math word problems) in three domains, and (2) the relationships between children's general creative thinking sills, measured by two divergent thinking tests, and children's creative performances. The findings of this study support the position that creative ability in young children is rather (but not absolutely0 domain-specific. Children exhibited a range of creative ability across different domains rather than a uniform creative ability in diverse domains, indicating there is considerable intra-individual variation in creative ability by domain. Divergent thinking measures did not have great power in predicting creative performance in at least two of three, if not all, domains assessed in the study. It is implied from the study that it is not possible to reliably predict a child"s creative ability in one domain based on his/her creative ability in other domains or his/her overall divergent thinking ability. Implication of the study in connection with educational practices for gifted children is discussed.

The purpose of this study was to explore the components of the geriatric robot pet, which might be helpful in caring for elderly people in the future. Focus group interview-with two focus groups-was performed between August 2014 and December 2014. Study participants were 13 geriatric experts from nursing, medicine, social work, and physical/occupational therapy. All interview data were transcribed, followed by debriefing and a qualitative content analysis. Three main themes emerged: acknowledgment of the usefulness of geriatric robot pet, establishment of elderly-centered appearance, and the functions of the robot pet to meet the needs of elders and family members. The robot pet was considered to be useful to elders who live alone since they can benefit from companionship and care provided by the robot pet. Geriatric robot pet needs to be manageable in size and weight, like a small dog. Moreover, a function that allows for interaction with and monitoring the elderly would be beneficial. The baseline elements that could guide further development of contents for the Korean geriatric robot pet were proposed from the results of FGI. Studies that validate these elements are necessary.

In this paper, I examine how the voice of Simcheong is reproduced and the meaning of it by examining the reconstruction method and characteristics of . And I tried to explore the possibilities and directions of contents based on classical literature by exploring the way in which this text reintermediation, and recreates the narrative of . This work deals with the story of ShimChung, and sees the problematic aspects of ShimChung's sacrifice and death through the gaze of the surrounding people such as the Namkyeong merchant and Guideok's mother while excluding the central characters Shimcheong and Shimbongsa. In the process, the voice of Simcheong was discovered as a victim and social hit. And It connects this with the discourse of filial duty and virtuous woman which regulates the life of women in the patriarchal society and establishes the place of social public opinion about the life of the women of the Joseon era. In this way, is presented the possibility of a new interpretation of . Also readers and audiences of present-day have an opportunity to reconsider the 'sacrifice' of social subordinate based on deep understanding of .

In this study, we surveyed the 68 teachers from eight science high school and four science academy for the gifted through questionnaires about research ethics education and ethical research environment in Korea. First, we examined the current state of research ethics education. Half of the responding schools included research ethics education in their curriculum. Although only half of the schools have this in their curriculum, more than half of the total number of teachers surveyed personally taught research ethics in class, and almost 90% of the teachers said they taught the research ethics during students' research activity. However, 63.24% of teachers said that research ethics education was not enough still. Second, we investigated the ethical research environment. In terms of knowledge and experience, the teachers were competent, and they were creating an environment that enabled peers and self-verification. However, research ethics, regulations and verification systems are not well equipped in schools. Since the principals are highly interested in research ethics education, there seems to be enough improvement on the ethical research environment. Finally, teachers said that additional research ethics education, change in student attitude, development and continuous maintenance of the verification system, encouragement to develop ethical environment, and clear guidelines were needed for ethical research of students. The result of this research will be able to provide the following. First, it will help set up a direction for research ethics education at every gifted school. Second, it will provide insights on how schools and teachers can create an ethical research environment for the students of science-gifted students.

The purpose of this study was to develop the evaluation scales that can access hierarchically the lifelong education field training program based on relevant stakeholders. To fulfill this purpose, both qualitative and quantitative research methods were applied. First of all, four groups of stakeholders were selected such as trainees, professors, field instructors, and program inspectors. The in-depth interviews with 13 experts in the field were conducted, and as a result, the scale with hierarchy of evaluation area, evaluation section, and evaluation item for each stakeholder was developed. In order to verify the content validity of the evaluation scales, delphi surveys for each stakeholder were conducted, using 35 expert panels. After delphi survey, the scale was applied to 90 trainees, 22 professors, and 31 field instructors. SPSS program was used to analyze the descriptive statistics, validity, and reliability. Finally, the evaluation scale of the trainer was identified as 8 evaluation areas, 14 evaluation sections and 51 evaluation items. And the professor's scale consisted of 6 areas, 10 sections and 40 items. The field instructor's scale was determined as 3 areas, 7 sections and 31 items, and the program inspector's evaluation scale was confirmed as 7 areas, 15 sections, and 32 items.

Service-Learning (S-L) is an experiential learning-based teaching-learning method that connects students with curriculum and school-based community service and raises students' academic ability and social responsibility awareness through the value of 'reflection' and 'reciprocity'. This study analyzed the case of S-L course of 'History of Science and Inquire Activity' for pre-service science teachers (PSTs). The S-L lectures linked to the subjects of the History of Science were conducted in terms of three stages (Preparation-Implementation-Evaluation), and S-L classes were conducted in three schools five times. The educational effects of S-L lectures were analyzed by collecting questionnaires, class observation and self-reported reflection diary. The PSTs were able to understand the school realities and improve the teaching abilities and pedagogic content knowledge through educational service activities. The PSTs who participated in the S-L course had hard time due to excessive learning time, the difficulty of preparing the class, the fear of the class, and trial and error. Nonetheless, most of the students responded that they were very satisfied (4.68) with the S-L lecture, and that they could develop self-efficacy for their future teaching career thank to this learning experience.

This study intends to rehabilitate the memories of the social other which have been gradually forgotten in the social events overloaded with the undemocratic violence in South Korea today. This study explores a case of Yongsan Tragedy in 2009 among the most tragic events. It notes the autonomous ways in which activist artists would like to memorize the socio-historical events anew despite the emptiness of public records. In other words, this study considers the Yongsan case to be significant that a group of the public, artists, grassroots activists, religion men got together in solidarity so as to create the contested narratives countering dominant memories and thus to signify the records written by the civil society. Among others, activist artists had documented the unofficial counter-memories of socially alienated peoples in terms of planning a series of artistic events such as opening some gallery exhibitions and performance events, issuing a volume of work books, comics and photographies, online broadcasting, and directing some documentaries. Especially, this paper tends to note the documentation of on-site activist artists to record the counter-memories against social oblivion. By doing so, it finally suggests how we could document the Yongsan Tragedy both to search out the archival implications of today's art activism and to insert those artistic records into the commonly shared counter-memories in a more inclusive way.
