The purpose of this study was to investigate beginning science teachers' perceptions of inquiry-based science instruction using open-ended questionnaire and semi-structured interview. Participants of this study voluntarily set up a goal of inquiry-based science instruction, planned inquiry-based science lessons, and shared and reflected their teaching experiences in their professional learning community for more than a year. Participant teachers recognized students' construction of core scientific concepts through performing scientific inquiry as a goal of science inquiry instruction. Participant teachers indicated that goals of science education such as 'learning scientific core concepts', 'improving students' interest of science', 'improving scientific thinking', and 'understanding the nature of science' can be achieved through students' active engagement in scientific inquiry. Participant teachers recognized not only the importance of teachers' role, but also what roles science teachers should play in order to enable students to perform scientific inquiry. Participant teachers emphasized teachers' roles such as 'identifying core concepts', 'reorganizing science curriculum', 'considering student ability', 'asking questions and providing feedbacks to students', 'explaining scientific concepts', and 'leading students' argumentation.'

In this study, we investigated the characteristics of planning lessons using analogies by pre-service science teachers. Eight pre-service teachers at a college of education in Seoul participated in this study. After the workshop of instructional analogies in science education, they planned lessons using analogies. We also conducted semi-structured interviews. For the analyses, we used a revised framework from a previous work which characterized the dimensions of teaching through analogies. The analyses of the results revealed that most pre-service teachers planned to use analogies in beginning or developing lesson and to present analogs before target concepts. The degree of activity allowed for students was not high. Many did not recognize the necessity of assessment and did not include assessment in planning lessons. They planned clarified mapping strategies which are teacher-centered and also not to cover unshared attributes and multiple analogies, because they thought that students could misunderstand mapping and unshared attributes could make students confused. Most planned to use figures, pictures, and videos to help students understand analogies that they presented. Educational implications of these findings are discussed.

Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

The purpose of this study was to develop practical problem-based home economics teaching.learning process plans about a unit 'the youth and consumer life' of middle school eighth-grade Technology and Home Economics by applying blended learning(BL) strategy. According to ADDIE instructional design model, this study was conducted in the following procedure: analysis, design/development, implementation, and evaluation. In the stage of design and development, the selected unit was converted into a practical problem-based unit, and practical problem-based teaching. learning process plans were designed in detail by using BL strategy. An online study room for practical problem-based home economics instruction grounded in BL strategy was prepared by using Edunet(http://community.edunet4u.net/${\sim}$consumer2). Eight-session lesson plans were mapped out, and study aids for students and materials for teachers were prepared. In the implementation stage, the first-session teaching plans that dealt with a minor question 'what preparations should be made to become a wise consumer' were utilized when instruction was provided to 115 eighth graders who were in three different province, and the other one was in a middle school in the city of Daejeon. The experimental teaching was implemented for two weeks in the following procedure: preliminary program, pre-online learning, main instruction and post- online learning. The preliminary program was carried out in a session in the classroom, and pre-online learning was provided before the main instruction was given in a session in the classroom. After the main instruction was completed, post-online learning was offered. In the evaluation stage, a survey was conducted on all the learners and teachers to find out their opinions and suggestions.

The purpose of this study is to investigate implications for future STEAM education by analyzing the surveys by the in-service teachers who participated in the Advanced STEAM Teacher Training Program(ASTTP) for raising interests and understanding of science and technology and nurturing STEAM literacy and problem-solving ability of students. ASTTP was developed for promoting 'teacher competence for STEAM.' ASTTP is a 60-hour program(4 credits), which includes offline intensive course of 38 hours, online training course of 12 hours, a course of implementation at schools for 5 hours, and a workshop for 5 hours (based on the 2014 program). For the offline intensive course, teachers take various professional development classes and activities, such as open-laboratory tours, advanced experiments, mentoring programs, and team projects as well as lectures on diverse disciplines. For the online course, teachers take online classes freely while they are encouraged to work with other teachers in groups. After taking both online and offline courses, the teachers are required to implement their STEAM lesson plans in their classrooms. Finally at the workshop, some selected teachers share how successfully they have implemented STEAM education. About 700 teachers have successfully taken the program from 2012 to 2014. Based on the surveys by the teachers, the program has been modified and improved. Our analysis shows increased professional development in STEAM education for the participating teachers. This study can provide some implication and helpful insights for people who need to develop and manage teacher training programs for STEAM education and other education programs in general.

As 'Science Inquiry Experiment' is newly introduced in the high school curriculum, where inquiry and experiment oriented education is insufficient, this study aims to analyze teacher's practice of 'Science Inquiry Experiment' in depth and identify contradictions during its process in the perspective of Cultural Historical Activity Theory. The research participant is teacher SHIN who is exclusively responsible for Science Inquiry Experiment. Starting with reflection on the practice of Science Inquiry Experiment class conducted in the first semester, interviews with participants, participatory observation and local materials were used during the 2nd semester's Science Inquiry Experiment class. A descriptive analysis of the teacher SHIN's practice of Science Inquiry Experiment was carried out and the contradictions in the activity system of the teacher SHIN were identified. The result reveals that in the overall practice of teaching Integrated Science and Science Inquiry Experiment, there were contradictions between teacher SHIN's recognition about cooperation(subject) and shared responsibility with other teachers(division of labor), and between teacher SHIN's recognition about the subjects(subject) and contrasting contents in teacher training courses(community). In the practice of teaching Science Inquiry Experiment, there were specific contradictions between teacher SHIN's recognition about the subject(subject) and time of job assignment(rule), between experimental activities(object) and experimental tools(tool), and between purpose of the subject(object) and directions about assessment(rule). These contradictions directly or indirectly influence the practice of teaching Science Inquiry Experiment. There needs to be support for constructing an activity system capable of supporting and promoting teachers' practice of Science Inquiry Experiment, and we made several suggestions to resolve the problems.
