The aims of this research were to analyze and compare verbs in the contents of the 7th, 2007, and 2009 revised national curriculum for elementary and middle school science. After the investigation of 1383 verbs in description of achievement standards and inquiry, we found that 'to know'(15.0 %) in elementary school and 'to understand'(24.2 %) in middle school were the most frequently used ones, totally in these three curriculums. In the 7th national curriculum, frequently used verbs in elementary school were ones related with inquiry such as observation, investigation and so on though 'to understand' had the most common verbs. Secondly, 'to explain' ranked top among verbs in the 2007 revised national curriculum. It showed some possibility of influences of the discussion-oriented situation at that time. Finally, however, in 2009 revised national curriculum, 'to know' and 'to understand' occupied the first and second portion of the verb distribution. In addition, 'to understand' and 'to observe' were used evenly through three curriculums but the portions of 'to know' increased through curriculum revisions. Some implications and discussions were also added with suggestions for further researches.

Increasing the problem solving power in school mathematics is the most important task of mathematics education. It is the ultimate goal of mathematics education to help students develop their thinking and creativity and help solve problems that arise in the real world. In this study, we investigated the contents of problem solving according to mathematics curriculum goals from the first curriculum to current curriculum in Korea. This study analyzed the problem-solving contents of the mathematics textbooks reflecting the achievement criteria of the revised curriculum in 2015. As a result, it was the first curriculum to use the terminology of problem solving in the mathematics goal of Korea's curriculum. Interest in problem solving was most actively pursued in the 6th and 7th curriculum and the 2006 revision curriculum. After that, it was neglected to be reflected in textbooks since the 2009 revision curriculum, We have identified the problems of this problem-solving instruction and suggested improvement direction.

The purpose of this study was to deduct implications for national curriculum and textbook by analysing the duplicated contents and sequence between science and technology home economics subjects of the 2009 revised middle school curriculum. For duplication analysis, overlapped achievement standards and themes were examined by comparing the science and technology home economics curricular. Next, analysis of duplicated concepts is performed by comparing science and technology home economics textbooks through the concept map. The result of analyses of the achievement standards showed 4 standards related with 'digestion', 'energy' were duplicated. The other results of studying duplicated contents in textbooks suggested overlapped concepts(terms) were existed as following: digestion(22 contents), Energy(9 contents). In science textbook, the duplicated concept is usually described in detail. In contrast, the technology home economics textbook explain the duplicated concept briefly with providing various type of examples and cases. There are differences of using terminology between two subject textbooks. The findings of this study may provide educational insights into teaching of the duplicated contents between science and technology home economics.

In recent years, astronomy has been snowballing: including Higgs particle discovery, black hole imaging, extraterrestrial exploration, and deep space observation. Students are also largely interested in astronomy. The purpose of this study is to discover what needs to be improved in the current astronomy curriculum in light of recent scientists' researches and discoveries. We collected keywords from all papers published from 2011 to 2020 in four selected journals-ApJ, ApJL, A&A, and MNRAS- by R package to examine research trends. The curriculum contents were extracted by synthesizing the in-service teachers' coding results in the 2015 revised curriculum document of six subjects (Science, Integrated Science, Earth Science I, Earth Science II, Physics II, Convergence Science). The research results are as follows: first, keywords that appear steadily in astronomy are 'galaxies: formation, galaxy: active, star: formation, accretion, method: numerical.' Second, astronomy curriculum includes all areas except the 'High Energy Astrophysical Phenomena' area within the common science curriculum learned by all students. Third, it is necessary to review the placement of content elements by subject and grade and to consider introducing new concepts based on astronomy research keywords. This is an exploratory study to compare curriculum and the field of scientific research that forms the basis of the subject. We expect to provide implications for a future revision of the astronomy curriculum as a primary ground investigation.

CRESST(the National Center for Research on Evaluation, Standards, and Student Testing at UCLA) is now carrying out the research, which was scheduled for a five year period from 2007 to 2011. This research aimed at testing the effectiveness of the formative assessment program by continuously conducting the program on the target group and steadily applying the recurring feedback, in order to reform the teachers' teaching and to facilitate students' learning. To do this, CRESST has set out to develop the material for 7th graders since January 2007, and KICE(Korea Institute of Curriculum and Evaluation) have been running a collaborated research since July 2007, while sharing the instructional materials developed by CRESST. In 2008, the pre-test was conducted prior to this study in 2009. Especially, this paper deals with the Korean 8th graders' scholastic achievements in algebra domain measured by PowerSource(c). In addition, this study would examine the responses of teachers and students on its application.

The purpose of this study is to develop and apply assessment standards for the reflection of science museum exhibitions in science curriculum. Assesment standards were developed based on the national achievement standards for earth science in elementary school. The researchers measured the reflection level and evaluation scale by applying the developed assesment standards to exhibitions in the National Science Museum. The results of this study showed that the reflection level and evaluation scale of science curriculum far elementary school in the National Science Museum were measured as 52% and 3.53 respectively. Especially, the level of the reflection of science curriculum in the National Science Museum was found to be at the high level in Geologic field and Astronomic field. These results indicate that the National Science Museum as an informal education institute is comparatively well connected to science education of elementary school. Science museum should be connected with school education and it should start after a substantial reflection on the curriculum. For this, science museum need to develop standards that reflect science curriculum. From this point of view, the results of this study can be used as basic data that evaluate the level of connection between science museum and school education and that guide the direction of development of science curriculum.

The purpose of this study is to examine the previous literature in home economics and contents and achievement standards of 2009 revised curruculum in relation to character education. To achieve this purpose 1) the literature review in human development and family, self-management and consumption life, food, clothing, and housing life area is critically discussed in relation to character education, and 2) curriculum contents and achievement standards are analysed in relation to the six pillars(trustworthiness, respect, responsibility, fairness, caring, and citizenship) of character education proposed by Josephson Institute. The results of analysis are verified by five experts in home economics content areas. Specific results of relation between home economics contents/achievement standards and six elements of character education are as follows. Human development and family area is most closely related with all elements of character education among other content areas. In Self-management and consumption life areas, self-management sub-area is very closely related with responsibility element; and consumption life sub-area is very closely related with citizenship element. In food area, health diet and eating sub-area is very closely related with trustworthiness, respect, and responsibility elements; and eco-frendly diet and food sub-area is very closely related with all six elements. In clothing area, clothing and self-expression sub-area is very closely related with trustworthiness, caring, and citizenship elements; and eco-friendly clothing and clothing reform sub-area is very closely related with responsibility, caring, and citizenship elements. In hosing area, housing and living environment sub-area is very closely related with responsibility and caring elements; and sustainable living and decorating living space sub-area is very closed related with trustworthiness, fairness, and citizenship elements.

A study on comprehension level of mathematical basic knowledge(MBK) of gifted students in middle school. The interest in mathematics gifted education is very high. However, in reality, there has been a shortage of the analysis of students' achievement result since mathematics gifted education began through the institute of gifted education in the education office in 2003. On this study, MBK is subdivided into definition, property and procedure and then examination questions arc developed on the basis of national level achievement standard. With these examination tools, total inspection was conducted in on metropolitan city and the result was analyzed. First, in a basic definition, relatively low achievement result was seen except the basic concept related operation. Second, in a basic property, very low achievement result was seen in the questions of basic property without basic definition and as a whole, the result was similar with the basic definition. Third, in basic procedure, the achievement result was very remarkable. This result shows we need tn increase the comprehension ability of MBK. To do this, the systematic alternative development of the questions of selecting gifted students and the contents of gifted education is required. This study proposes the meaningful implication to the selection question development related to the MBK and the improvement of gifted education contents. And it is expected to provide the positive change for mathematics gifted education.

This research aims to have some implications for revision of curriculum and textbooks by analysing connections between the 2009 revised national curriculum and its textbooks in elementary school mathematics. The results of analyses for 3~4 grades can be summarized in four aspects: Firstly, we noticed that the reconstructed achievement criteria were reflected properly in the textbooks except for use of calculators in 'Numbers and Operations'. Secondly, the analysis of connections between unit objectives of textbooks and the reconstructed achievement criteria suggests that 10 units must receive attention. Especially, the range of decimal numbers for adding and subtracting needs to be corrected. Thirdly, mathematical terms and symbols excluding 'unit fraction' were found in the textbooks. Finally, mathematical processes were also fully reflected in the textbooks. However 'simplifying' as a strategy for problem solving was only missing. This result shows good or poor connections between the curriculum and its textbooks, therefore it is expected to be used effectively to revise the national curriculum for mathematics and its textbooks.

The purpose of this study was to analyze the contents of middle school technology and home economics textbooks(family life area) that reflect the school career education goals and achievement standards in the 2015 revision of the Technology and Home Economics curriculum. Five different textbooks on middle school technology and home economics written based on the 2015 curriculum were selected and the school career education goals and achievement standards developed by the Korea Research Institute for Vocational Education and Training (2021) were used as a framework for textbook analysis. The results are as follows. First, the units that cover career education contents the most were 'life design and career choice(n=87)', 'developmental characteristics of adolescents(n=36)', and 'low birth rate, aging society, and work and family balance(n=31)'. The major contents of career education covered in technology and home economics textbooks(family life area) were 'search for various professionals(24.30%)', 'exploration of the changes in the future society(22.74%)', and 'exploration of the changes in the job world(18.66%)'. Thus it was found that the goals and achievement standards of school career education are evenly reflected in the middle school technology and home economics textbooks(family life area) based on the 2015 curriculum.
