  • The purpose of this study was to investigate the correlation among science gifted students' self-reported knowledge and self-perceived importance about Earth systems, and their science motivation. Ninety three seventh graders participated in this study who enrolled at Science Gifted Institute of K university. The correlation was measured by a validated Earth systems survey and Science Motivation Questionnaire (SMQ). The data were analyzed at the margin of error probability 0.05 using correlation and regression analysis. The result of reliability for items turned out high because the Cronbach's alphas were .896~.937. Results indicated that the correlation between self-reported knowledge on Earth systems and science motivation showed a correlation coefficient .656, whereas the correlation between importance on Earth systems and science motivation was .387, which was regarded as low. On the other hands, the result of regression analysis depicted that non-std. coefficients between students' self-reported knowledge about Earth systems and science motivation were .548 (.077), which lead to the conclusion that students' knowledge on Earth systems explained 43% of science motive-variation. It implied that Earth systems education program could impact the increased motivation of science gifted-students. Therefore, this study suggests that the various Earth systems education programs could be developed and implemented in order to increase students' motivation on studying science in general and Earth science in specific.

  • This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

  • In this study, we investigated the philosophical background and progress of the 2022 revised curriculum development in the high school earth science field. Research that was not covered in the research report includes the relevance of the transformative competency of OECD Education 2030, and that core ideas and achievement standards are organized around knowledge understanding, process functions, and value attitudes that constitute the learning compass needle. In addition, the composition of core ideas and Earth science electives in light of the understanding-centered curriculum, and IB type inquiry-based teaching and learning. Main research results include that the 2022 revised Earth science curriculum emphasized the student agency to foster the transformative competency and scientific literacy, and the curriculum document system in the field of earth science uses a learning compass needle. In addition, based on the understanding-centered curriculum, core ideas of Earth science were derived, and elective courses were organized to help students reach these core ideas. Also, IB-type inquiry-based teaching and learning was emphasized to foster student agency with knowledge construction competency. Based on the research results, slimming of the national and general level curriculum, the need to develop process-centered assessment methods for value and attitudes, the need for curriculum backward design, and ways to develop student agency through inquiry-based teaching and learning were suggested.

  • The purpose of this study was to analyze the questions of earth science knowledge presented in elementary science textbooks. In group activities, The questions were created by preservice elementary teachers assuming that they were teaching the earth science knowledge in science education classes at university of education. Types, frequencies, and sources of the cognitive background knowledge of the questions were analyzed. The results demonstrated the followings. First, types, concentrations, and sources of the cognitive background knowledge of the questions were different depending on the domains of earth science. Specifically, in astronomy domain, the frequencies and concentrations of the questions showed different trends compared with other domains in its individual lessons. It suggests that instructional strategies that reflected the difference found in each lessons be appropriately designed and used. Second, it was found that 'schools' was the most dominant sources of the cognitive background. 'Friends' were also found to be very important sources, thus promoting students' interaction with their peers would become an important strategy in science teaching. It was also found that mass media such as 'internet' and 'TV' were roughly rated the same as 'schools' which illustrated that mass media could be utilized in science instruction. Third, since types, concentrations, and frequencies of the questions were diverse in the lessons of units, it is suggested that diverse instruction strategies also be taken into account as an educational approach in teaching the subjects in teacher education.

  • Pedagogical content knowledge (PCK) has been regarded as an indication of science teachers' professionalism. The purpose of this study was to analyze topic-specific PCK of pre-service and in-service science teachers, comparatively. For this purpose, we developed an analytic framework for explicitly documenting science teacher' PCK and applied the framework for analyzing the difference within the same topic and with two different topics. Findings are as follows: (1) With the same topic, there was considerable difference between pre-service and in-service teachers in the components of PCK, not to mention individual difference. (2) In case of two different topics, we did not recognize a tendency of change in PCK, but remarkable differences in PCK were identified between two different topics. This study affirmed the topic specificity of PCK, and discussed a possibility of employing PCK analytic framework and its profile as one of the tools that could be used to develop and assess teachers' professionalism.

  • The purpose of this study is to develop a project-based learning program utilizing Earth science data and to evaluate its effects on students' knowledge-information processing competency and communication and collaboration competency. To achieve this, the ADDIE instructional design model was employed to create the program, which was then implemented with 75 second-year middle school students. The program's effectiveness was assessed using paired sample t-tests on the results of tests measuring knowledge-information processing competency and communication and collaboration competency. Additionally, reflection journals were analyzed to identify students' interest in and difficulties with the program. The study's conclusions are as follows: first, the Earth science data-based project learning program comprises three themes: 'Journey through the Planets of the Solar System,' 'I am a Marine Expert,' and 'Planning a Tidal Flat Experience Program.' Second, following the program's implementation, there was a significant improvement in the overall students' knowledge-information processing competency. Third, the program also led to a significant enhancement in students' communication and collaboration competency. Based on these findings, the study suggests the need for specific and continuous teacher support to provide students with successful experiences through the program, overcoming challenges in program implementation through collaboration with the information subject, and conducting research that microscopically analyzes students' interactions.
