  • 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.

  • The purpose of this study is to explore ways to change high school earth science elective courses with the introduction of the high school credit system in 2025, and ways to restructure them in preparation for the next curriculum revision. For this purpose, Delphi surveys with earth science education experts, a survey with in-service earth science teachers, and in-depth interviews with experts were conducted. According to the results, we need to consider four keywords such as cultivation of earth science literacy, connection with student career paths, emphasis on the fun of earth science itself, and student selection rate and college entrance exam in restructuring Earth science electives. Based on this direction, we composed four subjects: Earth System Science emphasizing earth science literacy, and three such subjects reinforcing career connection as Solid Earth Science, Atmospheric and Ocean Science, and Space Science. To resolve concerns about falling selection rate of earth science courses with the introduction of the high school credit system, it is necessary to re-establish the status of the earth science subjects including enhancing the career connection of the earth science electives. Follow-up studies are necessary to elaborate and publicize the titles and core concepts of Earth science electives.
