  • The purpose of this study was to analyze trends in conceptual change research in the field of Earth Science education conducted in Korea and to provide them as basic data of future concept change research. The trends of conceptual change research were analyzed in terms of keywords, year of publication, source of research, purpose of research, subject, area of research, and research method. This study was carried out on a total of 126 conceptual change papers of Earth Science education published from 1989 to July 2017. This study showed the following conclusions: First, the conceptual change research papers used more the term 'conceptual change' than 'misconceptions' and 'preconceptions'. Second, the conceptual change paper has achieved a large amount of growth in the 2000s. Third, conceptual change research tended to proceed to the subject of master's dissertation. Fourth, there were a lot of researches to find out the misconceptions and change them into the right concept, the conceptual change paper used free response test for misconceptions, and cognitive conflict instruction model and CAI (Computer Assisted Instruction) teaching strategy for misconceptions. Fifth, elementary school students were studied the most. Sixth, the study of conceptual changes in the field of Earth Science was high in the astronomical and atmospheric areas. Finally, although quantitative analysis methods were used in the early days of research, in the 2010s, qualitative analysis methods were widely used. In this paper, we proposed research on conceptual change for pre- and in-service teachers, expansion of research on conceptual changes in various fields such as geology, oceanography, atmosphere in Earth Science, investigation of causes of misconception in Earth Science and research on individual's affective factors, and so on.

  • Study courses using cognitive conflict strategy about geological stratum were performed on the 6th grade elementary students and their conceptual changes were investigated. Some misconceptions about geological stratum that the students have are as follows: (1) stratum was formed due to volcanic eruption, (2) gneiss composes the geological stratum, (3) folds in the stratum were formed due to vertical pressure from the top. The classes had positive effects on the changes of some the misconceptions: (1) the places where the stratum is filmed, (2) the kind of rock in the stratum, and (3) the reason for folding. However, there were no significant changes in the following items: (1) the reason that every layer consists of different sizes of grains. It shows that some misconceptions can be changed easily by cognitive conflict strategy, while others can not. We checked the students who didn't change their misconceptions after the test. These students have very strong misconceptions that most of the natural phenomena on the earth's surface are due to the internal heat pressure, and volcanic activity. Another affecting the students' misconceptions are the role of teachers in class and mass media, such as TV.

  • The purpose of this study is to classify types of preconception on the seasonal change to middle school students and to find out how the developed multimedia material changes their conception in the seasonal change. The questionnaire about the variation of season consisted of 10 items. Questions are given to 80 ninth graders. Control and experimental group was 23 and 57 students, respectively and they were instructed for two class periods. A learning method using multimedia was applied to the experimental group. On the other hand, traditional teaching-learning method was used for the control group. A learning method using multimedia in this study had an effect on the conceptual changes (p$<$0.01). Data in this study was divided into six levels to classify the changes of concepts in detail. As a result, it showed that a learning method using multimedia was effective for students to make progress from unscientific to scientific concepts, to build up scientific concepts, to build up scientific concepts, and to elaborate scientific concepts as compared with traditional method.

  • Preconceptions of middle school students related to chemical change the students are surveyed. The students are divided into experimental group that are learned by concept change theory teaching model, and control group that are learned by traditional teaching method based on science textbooks. After the planned classes, the tendencies of concept change of the two groups according to students learning motivations are analyzed. New teaching methods, which based on concept change learning model and students learning motivations, developed by this research. And the effects of the new teaching method are testified. As a result, it is proved that most of the students have a lot of preconceptions, and persist the wrong conceptions after the classes. This tendency is same in the control group and in the experimental group.

  • In science education, the research on students' conceptions has been started in early 1970. From the early 1980, the research on students' conceptions stimulated the research on conceptual change. Recently, mental model has been a theoretical background in concrete arguments on "how students' conceptions are constructed or created?" Mental model has been studied early in cognitive psychology, and several researchers have studied it partially in science education area. In this study, we compared different theories that explained students' conceptions in, mainly, physics. Further we discussed the possibility of mental model as a theory that could integrate different explanations about students' conceptions from different theory.

  • Cognitive conflict plays a very important role towards conceptual change in science education. Many research were conducted on the topic, but they were limited and failed to determine the effectiveness of cognitive conflict strategies for conceptual change on science instruction. It is worth noting that the levels of cognitive conflict varied the same given situation. Besides, the conceptual change resulted in different forms, despite the same level of cognitive conflict. Assuming that one explanation could be found in the learners' characteristics, this study investigated the cognitive conflict and scientific conceptual change by learners' characteristics of middle school students. A proper understanding of the cognitive conflict will help science teachers to apply effectively the strategies towards science conceptual instruction. In this study, learners' characteristics are 'intelligence', 'cognitive level', 'general grade of science subject', 'cognitive style', 'personality', and 'attitudes related to science'. The results says; the intensity of cognitive conflict correlated with students' personality (reflectiveness) and attitudes related to science, and conceptual change correlated with intelligence and cognitive level.

  • The purpose of this study is to investigate the effects of problem-solving inquiry teaching using concept sketches on conceptual changes about plate tectonics and science-related attitudes. The subjects of this study were two classes of second-year students of K high school located at Anseong in Gyeonggi Province. Before instruction, a conceptual test was conducted to survey student's preconceptions about plate tectonics. The control group took a traditional lesson, while the experimental group was applied to problem-solving inquiry teaching using concept sketches. After the inquiry instruction, TOSRA (Test of Science-Related Attitudes) was administered to find out changes in science-related attitudes of the two groups. The results of this study are as follows. The experimental group understood concepts of plate tectonics better than the control group, which means that problem-solving inquiry teaching using concept sketches was more effective in students' conceptual understanding. Science-related attitudes of the experimental group showed a significant change in the categories of 'normality of scientists', 'pleasure of science lessons', and 'interests on science as a hobby'. In conclusion, the instruction of problem-solving inquiry using concept sketches produced students' positive changes in conceptual understanding about plate tectonics and science-related attitudes.

  • This study was conducted on the alternative concept of elementary school pre-service teachers to seasonal changes. From May 2021 to June 2022, it was conducted with 60 pre-primary teachers at P National University of Education. The conclusion of this study is as follows. First, pre-primary teachers explained the cause of seasonal changes, and out of 60 pre-primary teachers, only 22 (36%) had scientific concepts, and the remaining 38 (64%) students had alternative concepts. Second, in explaining how the inclination of the Earth's axis of rotation is related to seasonal changes, only 16 (27%) of the 60 pre-primary teachers had a scientific concept, and the remaining 44 (73%) had alternative concepts. Third, pre-primary teachers explained the relationship between the change in the solar altitude and the seasonal change. Among 60 pre-primary teachers, 12 (20%) had a scientific concept, and the remaining 48 (80%) had alternative concepts. Fourth, looking at the comprehensive types of alternative concepts for seasonal changes, the aS-bS-cS type, which is classified as a type that explains the causes of seasonal changes using scientific concepts as a whole, was 8(13%) out of 60 pre-primary teachers. and the remaining 52 (87%) had at least one alternative concept to explain seasonal changes.

  • This study was designed to analyze the types of concepts about earth science related to seasonal changes, so as to develop a generative learning model focused on dissolving cognitive conflicts between the aforementioned concepts through debates and using said debates to find out how effectively the model works. There are 100 types of earth science concepts concering seasonal changes, 66 of which are unscientific in nature, including misconceptions. Through a second field trial and a research and development (R&D) process, a test on these concepts was developed, consisting of 14 items. For the experimental group, a four-phase generative learning strategy that reflects the types of earth science concepts and cognitive conflicts between such concepts was developed through pre-analysis and discussion, respectively. On the other hand, a traditional teaching and teaming strategy was used for the control group. A meaningful statistic gap found between the two groups through a covariance analysis, the significance level of which was 0.05. This result may be interpreted to mean that the generative teaming strategy is a possible alternative for correcting misconceptions about scientific concepts of seasonal changes.
