The goal of this study was to derive implications for the design of teacher training programs related to boxplots by examining the statistical reasoning patterns of mathematics teachers in group comparison tasks using boxplots. For this purpose, 48 secondary mathematics teachers who participated in a teacher statistics camp at a local office of education were selected as participants. Four sessions of teacher training were then conducted, including basic statistical concepts related to boxplots and group comparison activities using them. Afterwards, surveys with group comparison questions using boxplots and online interviews were conducted. The collected data were analyzed with a focus on the research questions. As a result, most participants relied on summary and spread elements to reason when comparing two groups using boxplots. On the other hand, participants paid little attention to shift and signal elements, and no responses using sampling elements were identified. Additionally, the overall comparative reasoning level of the participants was primarily at level 1 with the highest frequency (44%), and no responses reached level 3. Based on these research results, this paper derives implications for the design of teacher training programs related to boxplots and provides suggestions for follow-up research.

The purpose of this study was to investigate the educational needs targeted at city dwellers with hope of migration to mountain areas. 80 city dwellers participating in the education program operated by Korea Forestry Promotion Institute were selected. Results showed that city dwellers had higher preference for the education including medium scale(20-40 persons)and the type of camp with field experience. Real experiences and knowledge and understanding of migration to rural area are the most important element of the qualifications of the program teachers. In the contents of education, city dwellers wanted the teaching programs about 'how to have forest land', 'how to produce the forest products', 'field experience' and 'forest tourism' and so on. In other words, city dwellers who wanted to move to mountain areas were interested in basic things for living. In addition, it will need to investigate people who have real experiences migrating to mountain areas and then it is necessary to discuss educational needs and supporting system helping people can settle in mountain areas.

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exorcist habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

In this paper, to find out the direction of interest related to the SW education, SW education news data were gathered and its contents were analyzed. The topic analysis of SW education news was performed by collecting the data of July 23, 2013 to October 19, 2015. By analyzing the relationship among the most mentioned top 20 words with the web crawling using R, the result indicated that the 20 words are the closely relevant data as the thickness of the node size of the 20 words was balancing each other in the co-occurrence matrix graph focusing on the 'SW education' word. Moreover, our analysis revealed that the data were mainly composed of the topics about SW talent, SW support Program, SW educational mandate, SW camp, SW industry and the job creation. This could be used for big data analysis to find out the thoughts and interests of such people in the SW education.

This study presents an out-of-school problem-solving lesson we designed for American Indian students using a culturally relevant STEM topic. The lesson was titled "Shelter Design for Severe Weather Conditions." This shelter design lesson was developed based on an engineering design allowing us to integrate STEM topics within a traditional indigenous house-building context. This problem context was used to encourage students to apply their prior knowledge, experience, and community/cultural practice to solve problems. We implemented the lesson at a summer program on an American Indian reservation. Using the lesson, this study explores how American Indian students use cultural knowledge and experience to solve a STEM problem. We collected student data through pre- and post-STEM content knowledge tests, drawings and explanations of shelter models on the students' group worksheets, and classroom observations. We used interpretive and inductive methods to analyze the data. This study demonstrates that our culturally relevant, STEM problem-solving lesson helped the American Indian students solve a complex, real-world problem. This study examines how students' prior experiences and cultural knowledge affect their problem-solving strategies. Our findings have implications for further research on designing problem-solving lessons with culturally relevant STEM topics for students from historically marginalized populations.

The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.

Astronomy is the subject that can easily draw students' interest in studying science, therefore plays an important role in developing scientific core competence. However, it is difficult to develop spatial thinking that is required in understanding astronomical concepts through the classroom lessons. Planetarium, along with the science museum, is one of the most representative informal educational institution where astronomical concepts can be taught beyond time and space constraints. In this study, we developed the astronomy education program that is operated in the planetarium and applied the program to the elementary, middle and high-school students to investigate the effects of the planetarium lesson compared to the classroom lesson. The duration of this research was about 8 months, and the number of the students involved is 761, including participants of the 1 night and 2 days camps in the Daegu National Science Museum. The newly developed planetarium lesson is comparable to the previous classroom lesson of which topics are cardinal points, constellation, and the rotation of the earth. Test items were developed to evaluate the understanding of the astronomical concepts. The study was conducted based on the pre- and post-test with non-equivalent groups design comparing classroom and planetarium lessons. The results of this study are as follows. First, planetarium lesson is more effective for understanding astronomical concepts such as the cardinal points, earth's rotation, and the constellation than classroom lesson. Second, planetarium has a positive effect irrespective of gender and previous knowledge. Third, planetarium for high school students has the same effect as additional observation activities followed by the classroom instruction. Therefore, planetarium can be used as an alternative, effective tool when night observation is not available. In summary, planetarium is an effective tool that helps students to understand the astronomical concepts.

In modern society, private securities have developed their capabilities continuously. However, despite the fact that not only security industries have been considerably expanded in quantity, but also plenty of scholars published diverse papers relating to security problems, qualitative growths of private securities have not accomplished fully. Especially, securing the President would not be guaranteed only by PSS(Presidential Security Service). In order to secure the President successfully, it is necessary for all the social parts to strive to protect the President. In this respect, improving private securities, including academic fields, might be critical so as to succeed in securing the President. Without the supports from private securities, there might be lots of security problems in national context. Therefore, this study proposes several policy suggestions for the cooperation among PSS, private security industries and academic fields: (1) Providing a lot of practical knowledge from PSS to college students, (2) Personnel exchange between academic parts and PSS to promote the efficiency of securing the President, (3) Furnishing diverse information and knowledge about security to private securities, (4) Formulating security-searching standards, (5) Expanding educational institutions under PSS.
