This study was conducted to identify the level of problem-solving ability, critical thinking and satisfaction level of students majoring in dental hygiene, and to identify the impact of problem-solving ability and critical thinking on major satisfaction levels. The research target collected data through a structured questionnaire for 259 students majoring in dental hygienics located in North and South Gyeongsang Province. The analysis results showed that the problem-solving ability of the study subjects was 2.56, critical accidents were 2.58, and the major satisfaction level was 2.32, and the problem-solving ability, critical thinking and major satisfaction level were positively correlated with each other. Among the lower factors of problem solving ability, solution performance and solution model were significant factors that could improve major satisfaction, and among the lower factors of critical thinking, intellectual fairness, intellectual passion/interest, and systematicness were significant factors that could improve major satisfaction. Critical thinking also significantly mediated problem solving ability and major satisfaction level (β=).2602, BCCI [.0908~.4529]). Based on the results, it is believed that dental hygiene education needs to be developed in addition to the establishment of an educational environment that can enhance the ability to solve problems and critical thinking, and that research should be continued to check its effects.

This study empirically examines the relationship between the characteristics of a company and its performance through open innovation. It was intended to accept open innovation as a strategic means to overcome various situations in which companies faced and to understand it as a process of generating corporate performance. In various situations, companies must overcome environmental and internal factors. As an environmental factor, the dynamics of the market and the dynamics of technology allow for the adoption of open innovation, which in turn becomes a strategic tool for generating results. In addition, the internal environment of the company should strengthen the organization's capacity considering the characteristics of the company. In order to reinforce entrepreneurial orientation, openness of organizational culture, delegation and R & D capabilities, which are internal characteristics of the company, open innovation has a positive effect on the performance of the company. In overcoming the environment given to the company, open innovation was found to be an important medium for generating various results for the company. For this study, we conducted a structured questionnaire survey on 176 Korean companies. This study suggests that open innovation is strategically accepted and understood as a management strategic philosophy in order to overcome the environment in which a company is faced and generate results.

Middle-aged women who have experienced the depression have been in pain for a long time. Depression in middle-aged women, which is rapidly increasing from their forties, has a problem that do not decrease in spite of various treatment methods. If the essential cause of depression in middle-aged women is due to the inability to detect the meaning of life because of the lack of the perception about the identity resulting from self-loss, a more qualitative research for a fundamental treatment method is required. The purpose of this study is to find out the essence and meaning of the experience of depression in middle-aged women and to help them to find their own selves through the process of individualization and to recover the whole health as well as to live as a self-transcendent being. Three Christian middle-aged women falling on critical and serious condition by BDI diagnosis were selected for the study. In-depth counseling and interviews were held from January to August 2018. In-depth counseling has provided detailed statements about the process of individualization of middle-aged women who have experienced depression, which applied 5 stages of Giorgi's Phenomenological Research Methodology. As a result, 261 semantic units and 11 sub-components were derived and structured by dividing them into two themes: depression experience and the process of individualization process, which are the subject group. This study has its significance in realizing essential meaning of pain by middle-aged women who experience depression and fundamentally preparing an opportunity to be cured through the process of individualization, as well as contributing for such middle-aged women to have abundant living by suggesting preventive measures to general middle-aged women who prepare for their old age.

This study compares the perceptions of elementary gifted child and science teacher in a science class for the gifted. In order to explore the research problem, students and teachers answered a written semi-structured questionnaire and participated in interviews regarding the gifted science class. The data was collected and analyzed. Science teachers recognized the characteristics of a good science class, especially in terms of educational content and teaching methodology. First, they suggested promoting inquiry skills, presenting a challenging task in atypical topic selection, student-centered curriculum, and controlling the pace of learning to recognize individual differences. Second, in terms of the science class skills and attitudes category, teachers recommended raising mutual satisfaction through vigorous interaction within a permissible atmosphere. Finally, science teachers need to strive for continued professional growth. Gifted children, meanwhile, want to investigate a wide range of topics without time constraints. Additionally, they may have to explore challenging topics further. They prefer to act like scientists in that they enjoy group activities, communication and cooperation. In particular, they want to be evaluated by others in a totally embedded assessment. Gifted children also expect teachers to understand the life circumstances and needs of the students. In addition, they asked for teachers to respect individual experiments and to show them how to safely use new equipment or research methods. As a result, gifted children and science teachers have to recognize the differences of opinion concerning a good science class for the gifted. This study can help formulate strategies to establish quality management of materials in gifted science classes.

In this case study, we analyzed the STEAM lessons conducted by secondary science teachers in the perspective of the CHAT. Two science teachers at high schools in Seoul participated in this study. All of the teaching-learning materials were collected before lessons, and their lessons were observed and videotaped. We also observed the atmospheres in both school offices and classrooms. Semi-structured interviews were conducted before and after their lessons. All the data collected were categorized according to the elements of the activity system and analyzed by using the constant comparative method. The analyses of the results revealed that both teachers did not consider the student-centered self-directed activities in their STEAM lessons, but that they differed in the subject element such as teacher's professionalism on STEAM. Various elements of the activity system such as environmental characteristics of the school and policies about the STEAM influenced the performance of their STEAM lessons. Contradictions in the elements of the activity system brought about various changes. Successful experiences of the STEAM lessons by complex effects of the elements positively influenced their performances on their STEAM lessons. Based on these results, we have made some suggestions for the establishment of the STEAM in secondary schools.

In this study, we investigated the argumentations of group and classroom discussions in socioscientific issues (SSI) discussion classes. Twenty-seven high school students participated in the SSI discussion classes on nuclear power generation. We observed and recorded the classes and also conducted semi-structured interviews. For the analyses, we revised a previous framework that was developed to analyze dialogic argumentations in the context of SSI. The analyses of the results indicated that there were more discourse schemes in the classroom discussions than the group discussions which are related to awareness and openness to multiple perspectives, evidence based reasoning, and on-going inquiry and skepticism. And there were few discourse schemes related to moral and ethical sensitivity in the group and classroom discussions. Various grounds, data, and information were presented in the classroom discussions. Students concentrated on carrying their claims and were not able to sympathize with and accept other opinions. Therefore, there were few discourse schemes to reach consensus. In addition, they perceived classroom discussions as competitive and actively rebutted other claims or grounds. The levels of argumentation were also high in the classroom discussions. The group discussions were held in relaxed atmosphere, and they asked the opponents more for clarification or additional information and evidences. However, classroom discussions were held in serious atmosphere, and they actively queried the validity of the claims or grounds. Based on the results, some suggestions to implement SSI discussion classes were discussed.

Gestures accompanied by scientific discourses play an important role in constructing mental models and making model-based inferences. According to embodied cognition literature, gestures can be a source of recognition of the mental models of students and help them in changing naive beliefs about science. This study intends to compare the gestures of scientists with that of middle school students in explaining scientific phenomena and to explore the relationship between gestures and scientific discourse. In the study, 10 scientists and 10 middle school students participated in clinical interviews and the tests of knowledge and self-efficacy. Participants engaged in one-on-one clinical interviews with semi-structured questions about three tasks regarding the molecular movement and the state change of matter. Four researchers carried out open coding and applied a constant comparison method in order to analyze video-recorded gestures. This study found four themes (feature of gesture, use of gesture, content of gesture, function of gesture) about the differences of gestures between scientists and middle school students. Scientists used more diverse and elaborate gestures systematically and frequently in the interview. Although students used gestures in their scientific talk and reasoning, the gestures of students were not well grounded on scientific knowledge and had different functions from those of scientists. The findings revealed that gestures can represent underlying cognition and strengthen scientific thinking. We should encourage students to use gestures as a tool to understand scientific concepts and make inferences.

In this study, we investigated the characteristics of pre-service science teachers' curriculum design for lessons using self-generated analogy. Three pre-service science teachers at a college of education in Seoul participated in this study. After a workshop on lessons using self-generated analogy, they planned and demonstrated lessons. All of the teaching-learning materials were collected, and their lessons were observed and videotaped. Semi-structured interviews were also conducted before and after their lessons. The characteristics of lessons using self-generated analogy were analyzed in the perspectives of PCK. The analyses of the results revealed that they used various strategies to promote students' generating analogies. They lacked understanding of the stages of the lessons and the role of teachers. Although all of them considered assessment, they used limited assessment methods and assessment dimensions. Some actively considered students' misconceptions, and specifically anticipated analogies that students could generate. They determined topics for lessons considering various aspects such as the level of self-generated analogy and the characteristics of scientific conceptions. On the bases of the results, we suggest some educational implications for pre-service science teacher education.

In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.
