The purpose of this study is to research seasonal constellation experiments and to find out what are effective seasonal constellation experiments according to school salary. we organized seasonal constellation experiments with 24 elementary preparatory teachers and asked them to what effective experiments are for each school class. As a result, constellation learning through direct experience activities through role play is the most effective in elementary school, and in middle and high schools, using the stellarium program to realistically observe and reason about seasonal changes in constellations was selected as an effective experiment. Pre-service teachers recognized that experiments in which direct experience and specific manipulation activities were emphasized in elementary school, and experiments in which observation of realistic natural phenomena and reasoning activities were emphasized were effective in middle and high schools.

To learn the Earth's shape is a very important achievement standard in the earth science education. The purpose of this study is for helping school experiments by investigating effective experiments of the Earth's shape of each stage of school. Researchers suggest various experiment methods to learn the Earth's shape and investigated appropriate experiments to stage of elementary school, secondary school, high school and university for 26 pre-service teachers. As a result, there is difference between schools in effective experiments of the Earth's shape. Pre-service teachers thought that to observe a sail of ship to come back to a harbour is effective for elementary school students. And they responded that to compare the altitude of the polar star by latitudes is good for the secondary and high school students and to compare difference of sight according to height of the ground is effective for university students. They thought that level of the experiment method, abstract thinking and depth of background knowledge should be considered when teachers choose an effective experiment of the Earth's shape.

This study is to find out experiments of Earth's revolution and which experiment is effective by school level. Researcher investigated and developed eight experiments for students to learn Earth's revolution. Twenty six pre-service teachers did these experiments, discuss about them, chose an effective experiment of Earth's revolution and wrote the reason why. As a result, they thought that an experiment of seasonal constellations is effective for elementary school students, an experiment of seasonal star's spectrum is effective for secondary school students and an experiment of the superior planets' retrograde motion is effective for university students. Pre-service teachers gave reasons such as hands-on experience, connection with textbooks, background knowledge and higher-level thinking.

The purpose of this study is to assist school science class by investigating effective Earth's rotation experiments of districts by school level. The researcher investigated or developed nine experiments for learning Earth's rotation, and conducted and discussed these experiments with 26 elementary school teachers. Each teachers chose an effective Earth's rotation experiment for the district and wrote the reason. As a result, elementary school teachers chose the experiment that is easy to prepare and to do. And elementary school students are interested in the experiments by conducting them on their own. Middle and high school teachers chose more difficult experiments that could be connected with other concepts. University teachers chose effective experiments based on application of knowledge, active exploration, computer literacy, and difficulty.

To maximize educational effect with new educational methods in the 4th Industrial Revolution era, immersive education has become the core type of education and virtual reality (VR) is at the center of realistic content. VR education is increasing in school, but researches on VR production education are insufficient. Our study has proposed a school-level curriculum for students to create their own VR content. The output and the survey results were analyzed to find out the learner characteristics of elementary school students, middle school students, and pre-service teachers at each school level. As a result, there were some noticeable differences in concentration, content subject, and production time according to school level. Primary school students focused on their subjects, middle school students related to learning, and pre-service teachers put top priority on contents useful for primary education.

This study examines trends by school level, region, subject, and type centered on elementary schools when private education is perceived as a social problem due to the overheating of private education and its over-dependence. This study aims to provide a direction to ease the school mathematics education and meet the expectations of school mathematics education. As a result of this study, in mathematics subjects, the graph of private education expenses for mathematics subjects was not affected by the period and showed a somewhat consistent linear trend. In other words, we found that the private education cost of the mathematics subject was solid compared to other factors, and was not significantly affected by external variables, and was consistent. It is meaningful to examine the trends of private education costs in mathematics subjects with a comparison between the past and present and to grasp what factors and how they have changed and developed.

The purpose of this study was to compare the 5 OEs of Korean gifted elementary and middle school students and non-gifted, and to find out the gender differences and level of school differences to clarify the possibility of identification instrument of giftedness based on the 5 OEs as the affective factor of giftedness. Total subjects were 270 in this study. Among them, gifted group were 74, and non-gifted group were 196. Boys were 202, and girls were 168. Elementary students were 34, middle school students were 40 within the gifted group. OEQII (Kim, 2008) were modified and used for elementary students. The result of this study were as follows. First, the level of 5 OEs of gifted students was significantly higher than non-gifted students. Second, gender differences were found. Total OEs and sensory OE and emotional OE of girls were significantly higher than boys'. Third, there were significant interaction effects among gifted and non-gifted and gender factor in total OEs and psychomotor OE and sensory OE. Fourth, there was no significantly differences of 5 OEs between elementary and middle school gifted students, which may be interpreted that OEs were consistent affective factors of giftedness. OEs were discussed as the possibility of identification instrument of giftedness.

In this study, the direction for hierarchical curriculum organization about software education in Korea was suggested in terms of overall execution of software education. The international case studies especially was conducted in order to suggest the propel educational programming language for level of students in the programming activity. In terms of the international case studies, the type of programming language was examined, which is suggested to each school level as a part of required regular curriculum. Then, the direction was supposed to suggest the instructional system organization of software education for Korea through the result of case studies. The results of case studies indicated that elementary school use the block based programming language, and text based programming languages are used from middle school.

The Internet is one of the most infrastructure for information technology in school education. Providing the Internet with a proper bandwidth is an important element for efficient school education for information technology, especially because several instructional models based on new Internet technologies are under development. To support these instructional models, it is important for the schools to provide the proper Internet bandwidth wherever necessary. In this paper, the amount and pattern of internet usage in school were analyzed. Based on this analysis, we propose how to figure out a proper bandwidth for a different ladder of schools.
