The purpose of this research is to examine the current state of inserting illustrations in science textbooks under the 7th Revised Educational Curriculum which is currently enforced in all grades of elementary schools, and to compare and analyze the external and internal differences in illustrations in science textbooks of elementary schools in Singapore and Korea and to present desirable direction of producing illustrations. There are not only some differences in rate of the kinds and role of the illustrations in grades, but also in both countries. For example, in the case of illustrations for motivation, in both Korea and Singapore, interesting photos related to overall contents with regard to the contents of the unit are used. But in the 3rd and 4th grade class in Singapore, story types of cartoons related to learning subjects are presented to draw students' interest and attention. These need to be considered when developing textbook illustrations in the future.

The ultimate goal of environment education plays an important role in forming knowledge, skill, attitude and a point of value along with sustainable development in the regions. Recently, however, environment education is comparatively despised due to college-entrance-exam-focused education policy. Ironically, environment education is more actively implemented at informal institutes rather than formal ones. Environment education at schools is based on the school curriculum, but at informal educational institutes enjoy much more freedom in choosing learners, places and programs. Among them, the place is one of the most important factors of environment education. Therefore, in order to maximize the goal of environment education in this study, a specified program was developed and applied to a certain place to investigate its features and effects. Also the program was checked if it reflexes the environment education goal by using environment education program analysis frame. The results are as follows; according to the analysis of the program, the program was most effective for the two goals of offering hands-on experience and presenting motivations. The second most effective result of the program lied in the goal of knowledge, functions, value and attitude. And the teachers who used this program concluded that, when the program was applied to unmanned islands, offered stronger motivation due to their natural surroundings. Furthermore, direct experience is recommended because it can give us better conditions to collect data and to enhance interpretation ability.

The purpose of this study was to explore $6^{th}$ graders learning progression for lunar phase change focusing astronomical systems thinking. By analyzing the results of previous studies, we developed the constructed-response items, set up the hypothetical learning progressions, and developed the item analysis framework based on the hypothetical learning progressions. Before and after the instruction on the lunar phase change, we collected test data using the constructed-response items. The results of the assessment were used to validate the hypothetical learning progression. Through this, we were able to explore the learning progression of the earth-moon system in a bottom-up. As a result of the study, elementary students seemed to have difficulty in the transformation between the earth-based perspective and the space-based perspective. In addition, based on the elementary school students' learning progression on lunar phase change, we concluded that the concept of the lunar phase change was a bit difficult for elementary students to learn in elementary science curriculum.

The declination is an important concept because it is the underlying concept to understand the plate tectonics and also is used to decide one's location by using the compass and the map in real life. So this study surveys the description of declination being used in six of the seventh curriculum earth science II textbooks followed by the investigation of the possible of misconceptions that the highschool students might have. Utilizing an inventory of key concept, this study examines the actual misconceptions of highschool students, and investigates the relationship between misconceptions and textbooks. As a result, highschool students possess some misconceptions particularly with respect to the magnetic north pole which is caused by a lack of explanation about declination and by a wrong illustration. Therefore we suggest that detailed explanations of declination with non-dipole effect and precise illustrations be provided in the textbook for students th have a better understanding about declination.

The purpose of this study was to analyze the characteristics of students' academic achievement of middle school science curriculum achievement standards in the 2009 revised national curriculum and to generate implications for curriculum improvement. Based on the results of the 2015-2018 National Assessment of Educational Achievement (NAEA), we analyzed middle school students' mastery of 84 curriculum achievement standards. In the analysis, we used representative item information by achievement level and correct answer rate and checked the validity of the determination of mastery. According to the results of the analysis, 15 of the 84 achievement standards could not determine the degree of achievement. In science, many achievement standards could be mastered only by above-average group students. By achievement level, there were six achievement standards that advanced achievement-level students did not achieve, 38 achievement standards judged to represent mastery by advanced achievement-level students, 23 achievement standards judged to represent mastery by proficient achievement-level students, and two achievement standards judged to represent mastery by basic achievement-level students. By content area, the number of achievement standards corresponding to advanced and proficient levels was similar in the areas of motion and energy and earth and space domains. In the material and life domains, there were more achievement standards corresponding to advanced levels. Accordingly, it is necessary to reinforce customized teaching and learning activities in relation to achievement standards that were under-achieved.
