현재 과학교육의 목표는 과학적 소양의 함양이며 이를 구현하기 위해서는 교실에서의 과학탐구의 실현을 필수로 하고 있다. 과학자들이 경험하는 과학탐구는 "실질적 과학탐구(ASI)"라고 하여 필수적인 5가지 탐구요소(문제제기, 자료수집, 설명형성, 설명평가, 발표 및 정당화)를 포함하고 있다. 현재 사용하고 있는 지구과학내용의 교과서를 이 ASI 관점으로 분석하여 5가지 탐구요소의 분포도를 분석하고 이를 이용하여 지구과학탐구를 가르치는 초임교사를 대상으로 탐구에 대한 인식 및 교수실천을 같은 ASI관점으로 분석하였다. 탐구요소 2,3,4 에 해당하는 '증거수집', '설명형성' 그리고 '설명평가'는 빈번하게 나타났으나 탐구요소 1에 해당하는 '문제제기'나 5에 해당하는 '발표 및 정당화'의 기회는 나타나지 않았다. 특히 다른 과학(화학)과목 경우에 '증거수집'이 가장 빈번한 것에 비해 지구과학의 경우에는 '설명형성'이 주를 이루는 것은 지구과학탐구의 특징이라 할 수 있겠다. 또한 교과서 탐구기능은 SAPA로 분석한 결과 일반화, 의사소통, 예상, 그래프작성, 자료해석이 주를 이루었다. 과학적 소양을 함양을 위한 실질적인 과학탐구의 실현하기 위해서는 자유탐구와 같은 부차적인 기회를 통해서 경험하지 못한 ASI의 탐구요소의 기회를 학생들에게 부여해야 할 것이다. 또한 이 연구에 참여한 지구과학 초임교사의 과학탐구 인식 및 교수실천 또한 ASI로 분석한 결과 탐구요소 2번째에 치우친 경향을 보여주고 있었다. 실질적인 과학탐구의 실현을 위해서는 교과서에서 강조되는 탐구요소뿐만 아니라 다른 탐구요소를 경험할 수 있는 자유탐구를 개발하여 실용화해야 할 것이며, 관련 초임교사연수를 통해 초임교사들의 과학탐구에 대한 인식 및 교수실천의 반영 및 이들의 새로운 형성이 추진되어야 할 것이다.

Inquiring earth science phenomena is characterized by the followings: a big scale of time and space, inaccessibility, uncontrollability, and complexity. Thus, it is very difficult or, in some cases, impossible to investigate them through the actual manipulation in laboratories. Therefore, it is necessary to provide chance for students to experience scientific inquiry without actual manipulation in earth science classes. This study is to explore the role of reasoning based on a thought experiment as a representative model without actual manipulation, and to investigate features of various inquiry models using reasoning in classes. We can make implications when applying for applying each inquiry model to earth science classes, proposing a reasoning-based inquiry model embedded in earth scientific phenomena.

The purpose of this study is to explore a learning progression for integrated process skills in Earth science inquiry. For the purpose, a hypothetical learning progression (HLP) that capture how students' integrated process skills of science become sophisticated over time is developed through the literature review. This learning progression contains four components of the integrated process skills of science: designing inquiry, collecting data, analyzing data, and forming conclusion. Three hypothetico-deductive inquiry tasks of Earth science that start from recognition of the given problem to the forming conclusion are developed in order to document students' integrated process skills. A total of 126 students from middle, high, college level students participated in this study. After conducting the Earth science inquiry tasks, the integrated process skills of individual students are assessed by element based on HLP. In addition, the validation process for HLP was administered by applying the Rasch model using the students' assessment data. Finally, based on the analyzed data, the empirical learning progression (ELP) is developed by revising and supplementing the HLP. This study can help to find scaffolding methods to effectively improve the students' integrated process skills in Earth science inquiry class by identifying the factors that affect students' development of integrated process skills. It also provide implications for improving teachers' PCK of Earth science inquiry instruction.

The purpose of this study is to analyze the field of Earth science at a science fair. For this purpose, 566 pieces of data spanning 21 years (2000 to 2020), acquired from entries in the Earth Science section on the science fair website, were analyzed using the semantic network method. As a result, geoscience topics have been actively explored in works submitted for the Earth Science section of the science fair. Fossils from the Cretaceous period of the Mesozoic Era were particularly predominant. Together with these, keywords corresponding to astronomy, space science, and atmospheric science formed a small-scale network. Astronomy and space science mainly dealt with the dynamic characteristics of asteroids, Venus, and Jupiter. Other subjects included the solar system, sunspots, and lunar phases. Atmospheric science has focused on atmospheric physics, atmospheric observation and analysis technology, atmospheric dynamics, air quality monitoring, while marine science has been limited to physical oceanography and geologic oceanography. This study, is expected to help select Earth Science topics and conduct inquiry activities in schools.

Scientific literacy has long been as one of the key goals of science education, and using scientific inquiry in school science has became an important objective to be achieved. The processes of scientific inquiry consist of proposing/developing inquiry question, designing and conducting investigation, collecting, analyzing and interpreting data, and communicating the results. However, most students experience mainly collecting and transforming data in inquiry processes in science class and they are barely exposed to the opportunities of proposing/developing inquiry questions. Middle school earth science preservice teachers participated in this study (N=36) and their abilities of developing inquiry questions were surveyed. Participants' abilities of developing inquiry questions were investigated whether they were enhanced with activities using the Inquiry Questions Development Guide (IQDG). Also, this study was interested in whether there was any relationship between abilities of developing inquiry questions and designing inquiry investigation. The results of this study were as follows; first, the level and preciseness of inquiry questions and its preciseness developed by participating teachers were enhanced after experiencing IQDG. In addition, teachers' dominating inquiry question-types were two: one is a 'relationship-inquiry question' in which students could discover the relationship between results found in the given experimental situations and the other one is a 'why-how inquiry problem' in which students could explore a cause or a process that results in the outcomes. Finally, the higher level of and preciseness the of inquiry questions were identified as an important factor the determined teachers' abilities of designing more logical investigation. A process of proposing/developing inquiry question was identified as one of the most important processes contributing to a success of scientific inquiry investigation.

The purpose of this study was to develop an inquiry analysis framework based on the features of earth science inquiry methodology and to analyze inquiry activities in the 8th grade 'Earth History and Diastrophism' unit by using this framework. The framework classified earth science methods as logical inference, hermeneutic, and historical methods, each of which was subdivided in consideration of its subordinate methods and characteristics. The analysis revealed that the logical inference method reflected in the unit as the 'abductive method' (70%) was used more frequently than the 'inductive' (23%) and 'deductive' (22%) methods. The hermeneutic method was found in terms of the 'forestructures of understanding' (92%), 'circular reasoning' (9%). and 'historical nature of human understanding' (17%). The historical method also used as the 'constructing proper taxonomy' (53%), 'adhering to the modem principle of uniformitarianism' (47%), and 'relic interpretation' (41%) were identified with ratios more fester than those for the 'place substituting for time in stage theorizing' (3%) and 'evaluating independent lines of inquiry for convergence' (3%).

The purpose of this study was to investigate the tendency of inquiry of earth science content presented in North Korean textbooks of the 2013 National curriculum using Romey's method, and to help use as basic data for better understanding earth science education in North Korea. The content of earth science in the text, figure, question, and activity index of textbooks of Natural Science 1 and 2, Chosun Geography 2 of elementary junior high school, and of Geography 1 of advanced junior high school were all analyzed using Romey's method. The results of this study were as follows: First, the atmospheric science question and the astronomy text showed the tendency of inquiry type. Second, the proportion of oceanography was relatively small. Third, there were many non-inquiry questions or excessive inquiry questions, and both types of questions needed to be balanced. Fourth, there were a tendency that did not emphasize inquiry learning. Finally, the quantitative and qualitative level of inquiry tendency should be improved. In this paper, we propose to use a qualitative method when analyzing earth science content in North Korean textbooks, and suggested that we should further study the comparative analysis of inquiry tendency of earth science content using South and North Korean textbooks.

The purpose of this study is to investigate the relationship between lunar and earth rotation, by quantitatively describing the rotation of lunar configuration which is observed during the lunar diurnal motion. Our research suggests that observation of the lunar diurnal motion could be used as a study topic in the earth science courses. The rotation of the lunar configuration is an apparent phenomenon that can be seen when an observer. standing on the ground. looks at the moon as if the lunar dark configuration rotates on the basis of horizontal line. In spite its competence as a study topic because it is observable by naked eyes, there are only few major textbooks that introduce this phenomenon with regard to the earth rotation. Therefore, this study induced the mathematical principle of the lunar rotation in detail and proposed that this could be developed as a scientific inquiry through practical observation. In addition, an analytical proof and qualitative method of explanation of the lunar reverse rotation were also presented.
