Earticle

This study investigated that internalized images of earth scientist's work of 110 high school students who complete a course in Earth Science Ⅰ through drawing. As a result that reflected the character of earth science as a school subject, it is shown that nearly half of the students believe that earth scientist's working place is outside. An object of study is limited to such areas as astronomy and geology, it says that students has little understanding of areas of atmospheric and oceanic sciences. There are lots of answers that tools for working are telescope or microscope, it reveals a huge difference between the results of advanced research that analyzed the typical experimental devices, and students realized that working is not invention but survey. We should try students to recognize earth scientist as a job with relation to their future.

The education should adapt learners well to any changes and have them create something for such a era. Form the point of this view. question sheet was developed for middle school students to improve their scientific creativity. For this study, 146 item questions, which was from chapter 7 about solar system movement in the 3rd grade textbook for middle school students, was developed. For 5 weeks, 142 third graders in middle school were chosen and observed. They were divided into an experimental group and a control group. The teaching model using question sheet was applied to the experimental group, while the traditional teaching model, to the control group. This study compared two groups based on scientific creativity and academic achievement. In both scientific creativity and academic achievement, the group using question sheet showed meaningful differences. This result of the analysis indicated that teaching model using question sheet stimulated student's creative thinking and helped them to achieve a goal of lesson. The teaching model using question sheet can be used as an effective way to increase students' creativity.

본 연구는 우리나라의 과학과 교육과정 중 과학 적 소양이 교육의 목표로 제시된 7차 교육과정부터 2015 개정 교육과정까지 ‘과학’ 과목의 지구과학 영역 내용 변화를 과학적 소양의 측면에서 알아보 기 위해 실시되었다. 지구과학 영역을 천문, 지질, 기상, 해양 내용으로 구분하여 과학적 소양의 요소 중에서 STS적인 요소에 초점을 두고 내용을 분석 하였다. 천문과 기상 내용 영역에서는 7차부터 2015 개정 교육과정까지 모든 시기에서 과학적 소 양의 측면이 나타났으며, 지질 영역에서는 2007 개 정 교육과정, 해양 영역에서는 7차 교육과정을 제 외하고 모든 시기에서 과학적 소양의 측면이 나타 났다. 천문 내용 영역에서는 과학과 기술의 유용성 이 강조되었고, 지질과 기상 내용 영역에서는 일상 생활에서의 과학의 이용이 강조되었다. 해양 내용 영역에서는 자원부족과 환경오염 등 과학관련 사 회적 이슈가 강조됨을 알 수 있었다. 이 연구는 우 리나라 과학과 교육과정을 과학적 소양이라는 새 로운 측면에서 살펴보려는 시도로 차후 지구과학 의 다른 영역 및 물리, 화학, 생물 과목으로 확대하 여 내용을 살펴볼 수 있을 것이며, 더 나아가 기존 의 물리, 화학, 생물, 지구과학이라는 과목의 테두 리에서 벗어나 통합된 학문의 관점에서 과학적 소 양을 알아볼 것을 제안한다.

This study is conducted to search about changing earth science contents influenced by the scientific literacy from the 7th curriculum to the 2015 revised curriculum. Earth science area is divided into astronomy, geology, meteorology and oceanography contents. Among the elements of scientific literacy, the contents were analyzed focusing on STS elements. In the astronomical and meteorological content areas, there were aspects of scientific literacy in all periods from the 7th to the 2015 revised curriculum. Except for the 2007 revised curriculum in the geological area and the 7th curriculum in the oceanographic content area, the aspects of scientific literacy appeared at all times. It is emphasized the usefulness of science and technology in the astronomical content area and the use of science in everyday life in geological and meteorological content area. In the oceanographic content area, it is emphasized that content of science related social issue such as resource shortage and environmental pollution. This study can be extended to the fields of physics, chemistry and life science, we suggest to inquire the scientific literacy as a integrated science.

This study is to develop a valid and reliable instrument for measuring students’ creative engineering problem solving propensity. The creative engineering problem solving is operationally defined in this study as a creative problem solving skill in an engineering context. To develop the instrument, first we define seven common constructs between engineering problem solving skill and creative problem solving skill through an intensive literature review; motivation, context, personal character, engineering design, engienering habits of mind, understandings of engineering and engineers, communication skill, and collaboration skill. Based on the seven constructs and the face validity test conducted by two in-service science teachers and 4 experts in science education research, 40 preliminary items were developed. Then the preliminary instrument was implemented in a science gifted highschool to measure the reliability of the instrument. From the 40 items, 34 items were selected through the initial reliability test by Cronbach’s α (>.75). Finally through the three times of factor analysis process, 28 items in five construct categories were selected; motivation (3 items), engineering design (6 items), engineering habits of mind (9 items), understandings of engineering and engineers (4 items), communication and collaboration skill (6 items). The factor analysis result showed that the reliability of each construct category was between .733 to .892., meaning that the instrument is reliable in terms of the higher structural validity (each item is categorized in an appropriate construct category). We expect that the creative engineering problem solving propensity instrument developed in this study can be used in various contexts for STEAM education research as a reliable and valid instrument

이 연구의 목적은 탐구과정이 강조된 킬링 곡선 활동 중심의 프로그램을 개발하여 적용해 봄으로 써 초등학생의 기후소양에 어떠한 변화가 있는지 확인해 보고자 한 것이다. 대부분의 학생들은 최근 100년간의 기온 상승의 폭이 얼마나 심각한 현상인 지 제대로 이해하지 못하고 단순히 지식으로만 받 아들이고 있고 이로 인해 실질적인 기후변화 관련 태도의 변화를 이끌어 내는데 한계가 있었다. 그래 서 개발한 프로그램에서는 과거의 기후변동 자료 와 비교해 볼 수 있도록 다양한 질문과 탐구 전략 을 적용하였다. 연구 결과, 실험집단의 46명의 학생 들은 인지적 영역, 정의적 영역의 비판적 사고력, 실천적 영역에서 통계적으로 유의미한 효과가 있 음을 알 수 있었다. 또한 교사들의 수업 관점표 분 석과 학생들의 인터뷰 내용 결과, 개발한 수업이 학생들의 기후소양 향상에 도움이 될 수 있다는 연 구자의 의견을 지지하였다.

The purpose of this study was to find out the effects of climate change education program focused on the keeling curve activities highlighting inquiry process on elementary students’ climate literacy. Most of the students have not been able to correctly understand just how serious phenomenon that the temperature rise of the last 100 years is. As a result, there is educational limitations in order to bring about a substantial change in the attitudes toward climate change. So the development program was applied to various questions and explored strategies in order to compare with past climate change data. The results described that 46 students in the experimental group had statistically significant effects on cognitive domain, critical thinking of affective domain and practical domain. In addition, as a result of the analysis of teachers' instructional perspectives and students interview, they supported the researcher's opinion that the developed program could help students improve the climate literacy.

This study was conducted to investigate the effect of science based on question-centered Havruta learning on the logical thinking and the science related attitude of elementary students. The number of participants were 93, 4 classes of 4th graders in G elementary school in C city. The experimental group, 2 classes including 46 participants, took science lessons based on question centered Havruta learning while the comparative group, 2 classes including 47 participants, took teacher-driven lessons using teacher’s guidebook. Pre and post tests were done before and after executing lessons to assess the changing in each group’s logical thinking and the science related attitude. And targeting experimental group, a perception survey toward Havruta learning was carried out and the results were arranged. The results of this study can be summarized as follows: First, the pre and post test results of logical thinking revealed that the experimental group showed higher improvement compared to the comparative group and the difference was meaningful. This implies that question centered Havruta classe has the effect of improving students’ logical thinking. Second, from the pre and post test results of the science related attitude, we saw that the experimental group showed higher improvement compared to the comparative group and the difference was meaningful. This confirms that question centered Havruta class has the effect of improving students’ science related attitude. Third, the survey regarding perspectives of experimental group students toward Havruta learning showed that students had a high satisfaction level.

The purpose of this study is to investigate the effect of observing material on the phase change of moon considering the orbits of earth and moon for elementary school students. For this study, the material which shows the orbit of moon tilted at 5 ° with the orbit of earth is developed. 110 6th grade students in an elementary school are sampled. They are divided into the experimental group and the control group. The lessons using the material developed in this study are implemented to the experimental group, and the lessons using the material proposed in ordinary textbook are implemented to the control group. The pre, post, delayed concept tests on the phase change of moon are administered to the students of the experimental group and the control group, and semi-structured interviews are conducted for each concept level. According to students' responses, the concept levels are divided into 'Phase recognition', 'Space viewpoint', 'Earth viewpoint', and 'No recognition'. The experimental group and the control group are homogeneous in the pre-test. The result of this study shows that the experimental group gains significantly more scores than the control group in the post and delayed tests. Also, in the post and delayed tests, more students of the experimental group are in the highest level 'Phase recognition' than the control group. Finally, students of the experimental group who were in the 'Phase recognition' and 'Space viewpoint' explain more scientifically than the students of the control group. Therefore the results of this study show that the observing material on the phase change of moon considering the orbits of earth and moon is effective.

The purpose of this study is to investigate the effects of pre-service teachers of elementary school who take courses in 'Science and Textbook Research' on science teaching efficacy and science knowledge after experimental treatment. For this purpose, this study was aimed at intensive course four classes (118 students) enrolled in the 'Science and Textbook Research' course and experimented from the beginning of September to the end of November. The experiment was about teaching textbooks and teaching methods for one semester, and the pre- service teachers of elementary school made the demonstration of science cooperation classes by group. The results and analysis of the study were analyzed by the corresponding sample test in before and after the group test. The conclusion of the study is as follows. First, after taking this class the pre - service teachers of elementary school were effective in science teaching efficacy. Second, after taking this course, pre-service teachers of elementary school were effective in acquiring science knowledge.

The purpose of this study is to investigate the effect of elementary pre-service teacher’s science concept level on teaching difficulty, teaching satisfaction, and class evaluation. This study was conducted for 117 first grade students who are studying at P National University of Education. For this study, 117 students were divided into two groups according to the science concept level, and teaching difficulty, teaching satisfaction, and class evaluation score of the two groups were analyzed. The conclusion of this study is as follows. First, the elementary pre - service teacher group with a higher level of science concept showed significantly lower teaching difficulties than those with lower levels. This shows us that if primary pre-service teachers who have high science concept level, they can teach primary school science more effectively. Second, the elementary pre - service teacher group with high level of science concept got higher score on teaching satisfaction than the group with lower level of science concept, but it did not show statistically significant. Third, the elementary pre - service teachers with higher science concept level showed significantly higher scores on class evaluation than those with lower concept.
