  • The purpose of this study is to investigate both theoretically and empirically the roles of models in abductive reasoning for scientific problem solving. The context of the study is design-based research the goal of which is to develop inquiry learning programs in the domain of earth science, and the current article dealt with an early process of redesigning an abductive inquiry activity in geology. In the theoretical study, an extensive review was conducted with the literature addressing abduction and modeling together as research methods characterizing earth science. The result led to a tentative scheme for modeling-based abductive inference, which represented relationships among evidence, resource models, and explanatory models. This scheme was improved by the empirical study in which experts' reasoning for solving a geological problem was analyzed. The new scheme included the roles of critical evidence, critical resource models, and a scientifically sound explanatory model. Pedagogical implications for the support of student reasoning in modeling-based abductive inquiry in earth science was discussed.

  • The purposes of the study are to investigate the experiences of major stakeholders (i.e. science teachers, program instructors, local experts, etc.) who participated in implementing Community-Based Socioscientific Issues Programs (SSI-COMM) and to provide educational implications for further implementation. SSI-COMM dealt with three issues (i.e. abandoned pets, fine dust, and recycling) that students often encountered in their local community. Each program, lasting over 16 class periods in a free semester, included in-school and out-of-school activities in order to promote their interest and participation in community. Four teachers, four program instructors, and six local experts joined the interviews to explain their experience of participating in the programs. As a result, school teachers, program instructors, and local experts positively appreciated their experiences of the program implementation and perceived educational potentials of SSI-COMM. All the stakeholders mentioned that they became more interested in local socioscientific issues and strongly perceived the need for the implementation of such programs linked to their own community. The science teachers appreciated the opportunities to identify students' potentials through SSI-COMM and believed that SSI-COMM would contribute to reducing the gap between learning and practice. The program instructors, observed that out-of-school activities contributed to enhancing students' self-confidence and fulfillment in learning. Finally, the local experts obtained a sense of belonging to their community and were very satisfied with their contribution. The SSI-COMM programs are expected to be one of the educational models that will help to encourage the participation of students and stakeholders in facilitating educational activities in relation to the community.

  • Students experience a variety of achievement-related emotions during the process of learning the science curriculum. The purpose of this study is to develop an achievement emotions questionnaire for Korean middle school science curriculum to measure the achievement emotions that middle school students experience during study of this curriculum, and verified its validity. The Achievement Emotions Questionnaire-Korean Middle School Science is based on the English version of the Achievement Emotions Questionnaire, developed with reference to Korean middle school science curriculum and the characteristics of science study, from the perspective of the control-value theory of achievement. It has 232 questions, configured to measure nine achievement emotions across three types of academic settings. The questionnaire results can be treated with a high degree of confidence according to the result of our validation, which also verified that the achievement emotions of these students are configured with four internal criteria (learning strategy, achievement motivation and course grade), as suggested by the control-value theory; this in turn verifies that the nine achievement emotions are sufficiently distinctive across study situations. Last, it was verified that the questionnaire has sufficient external validity based on a comprehensive examination of the relation between science achievement emotions and the four criterion variables for each student. This suggests that through the development and implementation of this quantitative questionnaire, basic ground was provided to understand the achievement emotions experienced by middle school students learning the science curriculum.

  • The purpose of this study was to analyze the process of scientists' science knowledge generation by employing four creative scientists as participants. Raw protocols were collected by an intensive interview method and then analyzed by a psychological modelling procedure. The present study showed that the process of knowledge generation divided into the processes of inductive, abductive, and deductive thinking. Furthermore, the inductive process in simple and operative observation was involved in the processes of generating a question, conjecture/prediction, designing an operational method, operation, and simple observation. Also, the abductive process had two components; question generation, and hypothesis generation which consisted of analyzing questions, searching explicans, and constructing hypothesis. Finally, the deductive process involved inventing abstract test methods, inventing abstract criteria, inventing concrete test methods, inventing concrete criteria, collecting results, and evaluating hypotheses and stating conclusions.

  • The purpose of this study is to compare junior high school students' conceptual changes about force and motion and their interest in science between a group with the instruction including sports experiential learning activities and a group with traditional instruction. In addition, for a group with sports experiential learning activities, students' conceptual changes and interest were examined according to the degree of their sports-experience before the instruction.The subject was 7th-grade students(N=82), and they were divided into two groups: experimental group and control group. The conceptual changes were positive in both groups. In the multiple choice questions the experimental group students(20.0%) were more positively changed than the control group students(17.2%). The number of students who responded with the right explanation increased 26.7% in the experimental group and 10.4% in the control group. The interest of the control group was significantly increased in the topic dimension(p<0.05). The interest of the experimental group was significantly increased in the experiential activity and the communicative activity(p<0.05). Students who had much sports-experience showed the most positive changes. Moreover the interest of these students was especially increased in internal motive, receptive activity, experiential activity, and communicative activity.

  • The premise of the study is that teacher communities or teacher interest groups are one of the representative examples of Communities of Practice (CoP) formed by teachers who engage in the process of collective learning regarding science teaching. Based on the theory of CoP, we investigated and interpreted the process of identity development of six science teachers who have been actively involved in teacher communities. We conducted 2-3 individual interviews with the teachers in order to explore their narratives and personal experiences of being involved in the communities over the years. Results indicated that a teacher community is a place where the teachers not only generated and shared repertories of ideas, documents on teaching and learning, or routines (i.e. practices), but also formulated a set of relationships through social participation. Teacher communities actively provide the teachers a sense of joint enterprise and identity, and where the teachers have an opportunity to develop themselves personally and professionally as science teachers playing major roles in their communities.

  • In this study, we explored the meaning of astronomical observation activities of five earth science teachers through in-depth interviews. Semi-structured interviews were conducted after providing a questionnaire based on Seidman's three-step process of interview. By analyzing the interview transcript, the educational implications inherent in astronomical observation activities were extracted. Teachers have constructed systematic basis of observation and astronomy in the observational astronomy and laboratory class during their course in the teacher education institute. After they became in-service teachers, practical know-hows of astronomical observation activities in schools were developed with the help of colleagues. By designing and executing astronomical observation activities for students, teachers notice positive changes in the cognitive domain, affective domain, and career perception of the students. Hence, teachers consider that astronomical observation activities have great educational effects. In addition, astronomical activities appear to be very rewarding and satisfying experiences to teachers, by providing opportunities for having pride as an earth science teacher. However, teachers tend to find difficulties in operating astronomical observation activities in fields, due to both internal and external obstacles. It is found that the removal of internal obstacles is more important for teachers to attempt or to continue astronomical observation activities. In this sense, it is necessary to support teachers by providing timely training courses with related content, as well as opportunities to share their experiences within a peer group such as teachers' research society.

  • This study was to identify factors related to the experience of violence damage, focusing on health risk behavior of multi-cultural and general adolescents in Korea. Data from the 15th online survey of youth health behavior (2019) was used to analyze 35,574 adolescents. The data were analyzed using complex sample analysis by using SPSS/Win 22.0. The multi-cultural adolescents had significantly higher experience of smoking and habitual drug use and violence damage than those ordinary adolescents. In both multi-cultural and general adolescents, the more they did not live with their family, the more they had smoking experience and habitual drug use experience, the higher they experienced violence. The experience of violence victimization of general youth was significantly related to gender, school, economic status, and drinking experience. To prevent the violence victimization of adolescents, social support for adolescents who do not live with their families is required, and careful attention is needed to adolescents who have smoking and drug use experience. In addition, since multi-cultural youth are more vulnerable to health risk behaviors and violence damage than general youth, educational programs are needed to induce multi-cultural youth to practice correct health behaviors and prevent experiences of violence.

  • This study was conducted to examine the practical and educational implications of teachers' operation of the curriculum through science and online classes based on data collected for 4 months from 4 teachers who had experience in science subject online classes among homeroom teachers in the 3rd to 6th grades of elementary school in D city. This study was conducted through narrative inquiry. As a result of conducting interviews and in-depth interviews based on the online class experiences of the Earth Science Unit of the study subjects, and conducting field classes with related documents such as online class-related materials and teacher journals, teachers were more likely to take online classes compared to traditional face-to-face classes. They spent more time preparing and showed difficulties in the process of adapting to the new medium used in online classes. In addition, they demanded the provision of scientific materials produced in a pandemic situation and a teaching platform for smooth class operation. In particular, in the case of experimental classes, there is a burden of completing the planned curriculum, and in a pandemic situation, students felt the need for individual experimental tools for intensive science classes. As a result, it is necessary to introduce a blended learning learning system that combines the advantages of face-to-face and online classes as a new class form for the transition to future education in preparation for the pandemic. Continuous teacher research on the format and online class experience is required.

  • Researchers in science education have recently focused on service learning as an important educational approach to address environmental challenges including climate change. However, there are a limited number of studies focused on service learning in science education in Korea. In this study, based on existing related literature, the theoretical background of service learning is introduced and a conceptual framework that can be applied in the science education environment in Korea as a new approach to address environmental challenges is proposed. Given this, 112 relevant academic documents collected by searching a global database were analyzed. As a result, the theoretical background of service learning rooted in Dewey's experiential learning is introduced. Specifically, service learning is defined as a form of experiential learning that supports students in helping communities with structured services related to learning content, while at the same time fostering their in-depth understanding of content and engaging in civic and social responsibility as members of their community. In addition, a conceptual framework for service learning to address environmental challenges that can be applied to the science education environment in Korea is proposed. The proposed framework classifies the members of service learning into schools, students, and communities, and presents knowledge, experience, and learning through critical reflection as its core elements. It is important to actively implement service learning in science education to address various environmental challenges including climate change, biodiversity loss, air pollution, and deforestation, as just a few pressing challenges. Therefore, based on the proposed conceptual framework for service learning, studies that apply and verify diverse forms of educational approaches to addressing environmental challenges in local communities at school sites are needed.
