The purpose of this study is to examine the effects of small group discussion on elementary students' science writing. In this study, four 6th grade students were chosen from an elementary school in Seoul. Students were involved in eight science writing classes and the contents of a small group discussion and interactions were recorded and observed. Students' science works were collected and analysed based on three domains: scientific thinking, logic and originality. The result of this study showed that the contents of a small group discussion greatly affected the scientific thinking domain. A low-achieving student received lots of help from a high-achieving student. It was easy to improve in the logic domain through the science writing classes. Average students got good grades in an originality domain when the subject was related to their real life. A small group discussion would have an effect on science writing ability positively if the students acquired proper guidance on the procedure and manner of discussion. The science writing lesson would be more effective if the learning group was organized homogeneously in the aspects of intelligence achievement and interpersonal relationships.

The purpose of this study was to examine the effects of storytelling lessons using picture books on the resilience of adolescents and the parent-child relationships in the family unit of home economics subject in middle school. For this purpose, I selected picture books of five themes on family type, family relationship, family conflict, sexual violence, domestic violence, and family loss, and developed a teaching-learning process plan for 'Family class with picture book' using storytelling elements and techniques. The teaching-learning plan was applied to 194 middle school students in technology·home economics classes, and the learning effet was evaluated by comparing pre- and post-tests. As a result, the resilience level perceived by adolescents increased significantly after class, but no significant effect was found on self-expansion, which is a sub-factor of sociality. In the parent-child relationship of adolescents, the effect of instruction was shown in all areas, and the affectional bonds felt in the relationship with mother than with father showed higher increase. In the family unit of home economics, storytelling lesson through picture book seems to have a positive influence on the adolescents in their relationship with the family by bringing up the potential power in them to stand against the adversities they may face.
The purpose of this study was to develop e-learning contents and to examine how ICT-powered instruction using the developed e-learning contents affects the science achievements of students and how the students respond to that. After an experiment in the 7th class of the weather condition unit in high school earth science, e-learning contents were prepared by using the videotaped material and flash animation to teach key learning points. The selected two different classes, experimental and control groups, shows almost the same final scores in the first semester. The experimental group received ICT-powered instruction with the contents developed in the study, and the control group received a typical expository lesson. And then the achievement test was done to these two groups, separately. The major findings of the study were as follows: As for the effects of ICT-powered instruction on the academic achievement, the average scores of the experimental group is higher than that of the control group, but the difference is insignificant. When each group was subdivided into the upper and lower groups, the upper group got higher average scores and the difference was significant. But there was no significant disparity between the lower groups. Therefore, the ICT-powered instruction using the e-learning contents gives a good effect on the students whose levels are higher than the average. In the questionaike about the ICT instruction, they generally had a positive opinion about its impact on learning interest and class participation and its learning effects.
The purpose of this study was to investigate the recognition of middle school students on 'Thinking Science' activities and the influence on the understanding of the gas particles behavior concepts. For this study 125 students of four classes first grade in middle school were divided into two groups, the experimental and the control group. The SRT II test was carried out to identify the cognitive level of the students. The logical factors, needed to understand of the gas particles behavior concepts, were extracted. And the 9 'Thinking Science' activities designed to develop these factors were chosen and then implemented to the students of the experimental group. After the lesson for the gas particles behaviors, the achievement test of understanding of the gas particles behavior concepts and the survey of the students' recognition on 'Thinking Science' activities were administered. According to the results of the achievement test, there was not significant difference between the two groups on the whole. But only mature concrete operational students in the experimental group got high scores than those in the control group in analyzing the effect size. According to the results of the ANCOVA analysis, there was significant difference between the two girls' group. When students in the experimental group had a positive perceptions about 'Thinking Science' activities, they got higher achievement scores. This implied that there was a correlation between perception about 'Thinking Science' activities and their achievement in the gas particles behavior concepts. Especially, students with positive perception in mature concrete operational period got higher scores in science achievement. After the 'Thinking Science' activities, there was a high perceptions about improving in scientific thinking.
The teacher's questions presented in the problem-solving situation stimulate students' mathematical thinking and lead them to find a solution to the given problem situation. In this research, the types and functions of questions presented in chapters of Pattern area of the 2015 revised elementary school mathematics textbooks were compared and analyzed by grade cluster. Through this, it was attempted to obtain implications for teaching and learning in identifying the characteristics of questions and effectively using the questions when teaching Pattern area. As a result of this research, as grade clsuter increased, the number of questions per lesson presented in Pattern area increased. Frequency of the types of questions in textbooks was found to be high in the order of reasoning questions, factual questions, and open questions in common by grade cluster. In chapters of Pattern area, relatively many questions were presented that serve as functions to help guess, invent, and solve problems or to help mathematical reasoning in the process of finding rules. It can be inferred that these types of questions and their functions are related to the learning content by grade cluster and characteristics of grade cluster. Therefore, the results of this research can contribute to providing a reference material for devising questions when teaching Pattern area and further to the development of teaching and learning in Pattern area.

The purpose of this research is to develop a creative education program that utilizes AI education program based on big data for general education high schools, and to investigate its effectiveness. In order to achieve the purpose of the research, we developed a creative education program using artificial intelligence based on big data for first-year general high school students, and carried out on-site classes at schools and a validation process by experts. In order to measure the creative problem-solving ability and class satisfaction of high school students, a creative problem-solving ability test was conducted before and after the program application, and a class satisfaction test was conducted after the program. The results of this study are as follows. First, AI education program based on big data were statistically effective to improve the creative problem solving ability according to independent sample t test about 'problem discovery and analysis', 'idea generation', 'execution plan', 'conviction and communication', and 'innovation tendency' except 'execution', 'the difference between pre- and post-scores of male student and female student' on first year high school students. Secondly, in satisfaction conducted after classes of AI education program based on big data, the average of 'Satisfaction', 'Interest', 'Participation', 'Persistence' were 3.56 to 3.92, and the overall average was 3.78. Therefore, it was investigated that there was a lesson effect of the AI education program based on big data developed in this research.

This study aims to help elementary school teachers increase their knowledge about the changes in the positions of the sun and moon during the day and the first time the moon observation begins in the Earth and Space section of the Earth and the Moon. The survey questions were grouped into four categories, namely, textbook explanation, inquiry activities, achievement of learning goals, and other opinions. The perception of each question differed according to advanced science majors and teaching careers and experiences of this unit. In addition, understanding the diverse views of the participants using descriptive questions was possible. The study recruited 67 teachers working at an elementary school in Gyeonggi-do. The conclusion is as follows. First, the teachers exhibited similar positive and negative perceptions about the description of the textbook on the changes in the positions of the sun and moon during the day. Second, the study found that majority of teachers used alternative methods when guiding students regarding the change in the positions. This trend was not correlated with the sun and the moon, and the study observed no difference in advanced majors and teaching careers and experience of this unit. Third, the majority of teachers responded that they could achieve their learning goals through this learning. However, many teachers complained of various difficulties in guiding students about the lesson, and the majority alternative methods. The results demonstrated the perception of teachers that students can achieve learning goals through alternative methods without direct observation.
The purpose of this study was to analysis school dropout of specialized vocational high school students using phenomenological research method. The interview for the research was carried out with 10 adolescents who dropped out specialized vocational high school from December 8 to 23, 2018. According to the result of the research, 31 themes were extracted from interviews with 10 research participants. And 10 theme clusters were categorized from these. And these clusters were divided into 3 domains : 'before school dropout', 'causes & process of school dropout, feeling about school dropout', 'after school dropout' Based on the finding of the study, major conclusions of this study were as follow: First, adolescents who dropped out specialized vocational high school suffered from hard school life, disappointing lead from teachers, stereotypical lesson. And they committed misdeeds, and had psychological difficulties. Some of them kept up the good relationship with their friends, teachers, parents, some of them did not. Some of them kept up the good relationship with their friends, teachers and parents, while some of them did not. Second, they chose dropout due to various different causes. The procedures of school dropout proceeded with comparative ease. The effect of dropout prevention program is very limited. The feeling they felt at the time of school dropout varied individually. Some adolescents who dropped out specialized vocational high school were satisfied while others were stressed out, regretting their decision. Third, they lived diligently working part-time jobs or preparing General Equivalency Diploma (GED) test after dropout. They experienced positive changes in their daily lives after dropout. But sometimes they experienced various difficulties and negative changes. Most of them had their goals, and they were preparing for them. Their expectation was low that their life will succeed if they returned to school. They wanted people to understand their decision about dropout. And multiple institutions are supporting adolescents who dropped out specialized vocational high school. They need practical support : Various information, activity for career experience, counseling etc.
This study aims at investigating basic safety consciousness as preprocessing of the establishment of experience-oriented safety education center in which citizens can have positive and active experience education, based on the data for which the investigators have investigated and analyzed such citizens' safety consciousness as awareness, consciousness and feedback of national safety accident, systematic prevention of safety accident and necessity of first-aid when safety accident happens, focused on citizens in Seoul and Gyeonggi-do where more than 1/3 of the national population live, for the purpose of establishing experience-oriented education center where citizens can be taught to prevent accidents wisely, picking up experiences of large or small accidents up to now. And the findings from the study support the followings : 1) Ordinary people think that danger factors have prevailed in our entire society, and fear that the danger may come to them directly.2) Ordinary people's consciousness of safety accident is low, that is because selfishness and 'take-it-easy' manner have prevailed in our entire society. 3) Ordinary people have the dread of safety accident individually, but they don't know how to deal with safety accident when it happened. 4) Although most people have taken lessons about safety accident, they still feel the need to have systematic education about safety accident. 5) Children and survey-respondents are highly concerned with prevention of safety accident, but there were few people who sent their children to 'safety accident prevention program by outside institute', still less they didn't participate in the above program. And especially they complained a lot about safety education conducted by school. 6) Most people truly felt the need that they should have experience-oriented safety education center to be able to see, hear and experience. The considerations (or suggestions) resulting from the above findings from the study will turn out that people will need such recreation facilities, rest and play space that the family can enjoy as space for the prevention of safety accident, appliance for field lesson and space for developed program, and in light of visitors' convenience, safer and more convenient vehicle service will have to be offered.
SENKs (Students who Emigrated from North Korea to South Korea) are exposed to the general problem of Su-Po-Ja(mathematics give-uppers) as well as their own difficulty in learning mathematics. In this study, we conducted the FGI (focus group interview) in order to examine the recognition on mathematics teaching and learning in South Korea with 6 SENKs and 3 teachers who teach the SENKs. As a result, it was found that SENKs' had difficulties in understanding math because of the differences in math terminology used in South and that in North Korea, the unfamiliar problem situation used in math lesson, and the shortage of time for solving math problem. And the teachers reported that they had difficulties in teaching great deal of basic math, SENKs' weak will to learn math, and SENKs' lack of understanding about problem situation because of the inexperience about culture and society in South Korea.
