Software education is drawing attention as an education for fostering future talents who will lead the 4th industrial revolution. The purpose of software education for everyone from kinder to adults is not simply to develop programming skills, but to develop "Computational Thinking," a problem-solving ability that effectively solves real-world problems based on computing. Therefore, how to cultivate and evaluate computational thinking is a very important issue. This paper proposed a method of applying a process-based performance evaluation method to evaluate computational thinking ability in the process of solving learners' problems. The developed contents were revised and supplemented through two Delphi surveys by a group of experts consisting of five university professors and five incumbent information teachers majoring in computer science and computer education to verify the effectiveness of the final model. I hope This paper can contribute to the study of evaluating computer thinking ability from the perspective of problem solving.

The purpose of this study is to obtain implications for the improvement direction of astronomical education methods and development of educational materials or software. In connection with the 5th grade 1st semester elementary science 'Solar System and Stars' unit, elementary pre-service teachers were given a reorganization task to compare the relative distances from the sun to the planets, and then this was analyzed. Pre-service teachers are 11 male and 19 female students in the second year of the music education department at the elementary school teacher training university in B city. The implications of the study results are as follows. First, the 'distance comparison activity using a roll of tissue paper' is suitable for simply comparing the distances from the sun to the planet, but it has limitations in allowing students to experience the vastness of the solar system or inducing student participation-centered classes. Second, it is necessary to develop software materials for elementary school students that can simultaneously reflect the size of the planet and the distance to the planet that can be applied indoors, and also experience the vastness of the solar system, as well as a wide learning space. Third, textbook materials for students have an important influence on the class design of pre-service teachers.

The purpose of this study is to identify the types and characteristics of elementary school pre-service teachers revealed in the process of resolving the change of lunar phases, which emphasizes the context of actual observation, and to provide suggestions for areas to be considered in the elementary school teacher training program. To this end, we analyzed the 30 pre-service teachers' explaining the observable lunar phases, and the main research results are as follows. First, the phase change of the moon was often explained by introducing the timetable for each phase of the moon rather than based on observation of the phenomenon and scientific reasoning. Second, an alternative concept of the type that the moon is invisible when the sun rises or that the moon can always be observed has been identified. Third, there was a case of explaining that the time and orientation for observing the moon can be observed regardless of the position of the sun or when observing the sun. Also, the date of observing the moon was assumed to be approached by assuming the lunar calendar. Based on the above results, pedagogical implications were discussed.

The purpose of this study is to critically examine science content and science education from the 'essential-holistic' perspective, in particular, among the core disciplines constituting the teacher education curriculum. In this study, we first, analyzed the definition of the 'essential-holistic' perspective, the philosophical background, and the relationship with the practices in-depth, and then, from the 'essential-holistic' perspective, conducted an inquiry into the essence of science content and science education. The results of this study are as follows: first, according to the 'essential-holistic' perspective, science content is a study that explores the science practices and systematizes the results of that inquiry. Major activities of science content include the establishment and implementation of 'science for teachers' and participation in the development of science curriculum (textbook). Second, science education according to the 'essential-holistic' perspective is a study about in-depth exploration of essential problems in science education phenomena rooted in the science practices and the practice of good teaching. More specifically, science education is a field that carries out work related to inviting, participating, and guiding students to grow into science practices (i.e. initiating into practices). The main activities of science education related to this include activities ranging from the development of the science curriculum (textbook) to teaching and evaluation (recording). In this study, we discussed important tasks to be carried out in the future based on the results of the study.

우리들은 초 중등교육을 통해 암석의 종류와 특징, 지질형태와 퇴적구조, 그리고 화석에 대해 지속적으로 교육 받아왔다. 그러나 암석이나 노두를 보고 학교에서 배운 지식을 바르게 적용할 수 있는 학생은 매우 드물다. 또한 아름다운 경관을 보며 지질학적으로 형성과정을 해석할 수 있는 사람도 매우 드물 것이다. 여기서는 지질경관에 대한 정보를 어떻게 제공하고 있는가에 대한 연구 성과를 정리해보고 문제점을 도출하고자 한다. 현재까지 지질경관을 알려주는 연구 성과를 크게 나누면 3종류가 있다. 첫째, 지질학습장의 개발 및 활용에 관한 연구이다. 이 부류의 수집된 자료는 학위논문(29편)과 전문학술지(27편)로 현재 56편이나 검색에 따라 더 늘어날 것이다. 이들은 야외 노두에 대한 효과적인 지질학습을 위한 자료개발을 위주로 하고 있다. 이러한 내용들은 전문가 양성에는 대단히 좋은 프로그램이지만 청소년이나 일반대중들에게 너무 어려운 내용으로 구성되어 있다. 또한 교육청에서 주관하는 탐방계획으로 "경기도 지구과학교사 연구회"가 있는데, 주로 경기도 한탄강유역을 대상으로 하고 있다. 이 연구회 자료에서는 지역의 특성을 살린 야외지질학습장을 개발하고 현장에 적용하기 위한 노력을 볼 수가 있다. 두 번째로 과학전람회 자료로서 현장교사와 학생들의 야외학습에 대한 인식이 잘 나타나 있다. 수집된 자료는 총 55편으로 야외지질조사를 통해 관찰 자체에 중점을 두었는데, 최근에는 노두관찰에 덧붙여 탐구학습 태도와 창의성을 함양하는 쪽으로 옮겨가고 있다. 세 번째 자료는 일반대중을 위한 서적이다. 이 서적들은 저자들의 전공에 따라 그 내용이 다소 다르다. 즉 일반여행안내 책자는 노두나 암석은 소개하고 있으나 지질학적 설명이 전혀없으며(예, 남도해안 2000리), 지리학자들의 저술에는 지형의 형성을 지질학적으로 설명하려 애쓴 흔적이 보인다(예, 한국지리이야기). 다음으로 지구과학들의 저술은 전형적인 지질답사 안내서에 가까워 내용 자체는 좋으나 흥미가 다소 떨어진다(예, 가족이 함께 떠나는 지질여행, 제주도 지질여행). 지질학과 흥미를 적절히 혼합한 책으로 '우리 땅 과학 답사기'정도가 있다. 최근 한국암석학회에서는 "우리의 명산"을 지질과 경관의 관점에서 해석하려는 심포지엄을 2차례 가졌다. 그러나 그 내용면에서는 경관지질이라는 개념을 정립했다고 보기에는 다소 미흡 하나, 황상구 교수의 주왕산에 관한 내용은 앞으로 경관지질 연구에 대한 발전의 여지를 보여주었다. 앞으로 지질경관에 대하여 지질학적 야외답사나 과학지식 습득에 국한시키지 말고, 그 지역의 특성을 살린 관광 또는 민속과 연계하여 지구과학적 학습효과와 더불어 인성교육에 도움이 되는 학습 콘텐츠를 개발하도록 노력해야 할 것이다. 일반 대중이 우리나라의 빼어난 지질 경관을 손쉽게 이해하고 즐기게 되면, 세계자연유산이나 세계지질공원을 지정 받는 과정도 더 쉬워질 것이다.

The purpose of this study was to investigate the current status of pre-service curriculums for child care teachers at universities and colleges in Korea. To accomplish this, a survey was implemented to gather the lists of courses from each department training pre-service child care teachers. A total of 225 departments at universities and colleges across Korea participated in the survey. The results showed that the 37 different courses offered for child-care teacher licensure were different by school type (university or college) and major. Departments in colleges with specific majors such as early childhood education and social welfare offer courses that are also required for other certificates, including kindergarten teachers or social workers, so pre-service child care teachers may not have the opportunity to take courses specifically designed for their specific teaching needs or interests. Accordingly, there may be a restricted number of courses from which to choose during pre-service training periods. Based on the findings from this study, several political implications for improving child-care teacher professionalism were suggested.

The purpose of the study is to reflect on 'myself' as a teacher educator of college of education in depth and to improve my instruction through self-study with three critical collaborators. 17 pre-service science teachers and I have participated in this study of a teacher educator's course since March 2016 after the preliminary practice in 2015. The video recorded the course for 11 weeks with about 40 hours of lessons. The data source also included teacher educator's reflective journals, lecture evaluations, online boards and so on. Questionnaires were distributed and answered both at the beginning and at the end of the course and pre-service teachers wrote their reflective journals. Four of them were in the focus group interviews. During the course, the weekly group meeting of critical collaborators analyzed the emerging issues based on the lesson clips and teacher educator's reflective journals with discussion for the course innovation. Four phases were revealed in the process and for the purpose of the course such as exploration, conflicts, challenges, and changes. The results showed that first, we identified tensions among the teacher educator's multiple identities as a lecturer, a faculty member, and a researcher. Second, there were differences between goals of teacher educator and pre-service teachers in the course, and this obstructed the success of the course sometimes. Third, these practices led to explore balanced alternative views and interpretations of the problem by critical views and to expand and improve our teaching practice and thinking. In addition, the self-study with critical collaborators helped to bring conflicts and issues below my practice to light for collaborative reflection and it gave a chance to understand ourselves as teacher educators in different ways.

The purpose of this study is to explore whether pre-service teachers majoring in earth science improve their perception of computational thinking through STEAM classes focused on engineering-based wave power plants. The STEAM class involved designing the most efficient wave power plant model. The survey on computational thinking practices, developed from previous research, was administered to 15 Earth science pre-service teachers to gauge their understanding of computational thinking. Each group developed an efficient wave power plant model based on the scientific principal of turbine operation using waves. The activities included problem recognition (problem solving), coding (coding and programming), creating a wave power plant model using a 3D printer (design and create model), and evaluating the output to correct errors (debugging). The pre-service teachers showed a high level of recognition of computational thinking practices, particularly in "logical thinking," with the top five practices out of 14 averaging five points each. However, participants lacked a clear understanding of certain computational thinking practices such as abstraction, problem decomposition, and using bid data, with their comprehension of these decreasing after the STEAM lesson. Although there was a significant reduction in the misconception that computational thinking is "playing online games" (from 4.06 to 0.86), some participants still equated it with "thinking like a computer" and "using a computer to do calculations". The study found slight improvements in "problem solving" (3.73 to 4.33), "pattern recognition" (3.53 to 3.66), and "best tool selection" (4.26 to 4.66). To enhance computational thinking skills, a practice-oriented curriculum should be offered. Additional STEAM classes on diverse topics could lead to a significant improvement in computational thinking practices. Therefore, establishing an educational curriculum for multisituational learning is essential.

This study attempted to propose a theoretical model for STEAM education, entitled to the Ewha-STEAM education model, which could provide more concrete guidelines for science educators and curriculum developers to execute STEAM ideas. We identified key knowledge and key competencies to nurture future creative/convergent human resources. Key knowledge included an understanding of core ideas cutting across traditional disciplinary boundaries as well as the nature of different disciplines. And additionally, key competencies implied such abilities as to explore the scientific world, to resolve problems, and to communicate and collaborate with others. We also added creativity and character as an essential part of key competencies. In order to provide more specific guidelines when developing, implementing, and evaluating STEAM curriculum, we suggested three elements of convergence to consider: 1) unit of convergence (i.e. concept/skills, problem/phenomenon, activity), 2) degree of convergence (i.e. multi-disciplinary, inter-disciplinary, extra-disciplinary), and 3) context of convergence (i.e. personal, societal, global). It is expected that the Ewha-STEAM education model would contribute towards diverse education communities understanding the direction of STEAM education and its educational potentials.

The purpose of this study is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.
