Despite the importance of pattern learning for elementary school students, few studies have investigated in detail the understanding of patterns of lower-grade students. This study aimed to analyze the understanding of patterns of second-grade elementary school students. Since the patterns in the second grade are taught through the unit called Finding Rules, students' understanding of patterns was compared and contrasted before and after they learned the unit. To this end, a written instrument to measure students' understanding of patterns was developed on the basis of previous studies on pattern learning for lower-grade students. A total of 189 students were analyzed. As a result of the study, the overall correct answer rates in the post-test were higher in most items than those in the pre-test, illustrating the positive effect of the specific unit. However, students found it difficult to find rules in which two components would change simultaneously either in geometric or numeric patterns, find patterns that would be similar in structure, represent geometric patterns into numeric patterns, find empty terms in increasing patterns, and reason the specific terms in patterns that can be differently interpreted. Based on these research results, this study sheds light on students' understanding of patterns and suggests implications to improve their understanding.

The purpose of this study was to investigate the elementary school student's recognition of informal science education program : 'Korea Junior Engineering Achievement (KJEA)'case. The subjects were 807, 4th, 5th, 6th grade elementary school students who participated KJEA program. We developed questionnaires and explored the students' preference and the reason to KJEA (compared with school science lesson), attitude on informal elements of KJEA (non-school teachers and non-curricular content), interest in the each KJEA program, outcome of the KJEA. The result of this study showed that the students' recognition of the informal science education program was strongly affirmative. Students preferred KJEA program to school science lessons for that reason why they could make and do by themselves and the KJEA program had novelty. They expected more teaming opportunities by non-school teachers on non-curricular content. Though KJEA had little effect on career interests, students showed willingness to continue to participate. We could get implication for informal science education that the quality of the program is the most important factors than others. The novelty and the doing by oneselves were also important factors for students.

The purpose of this study were to investigate 1) present condition of children's usage of computer game, 2) difference in extent of immersing in computer game according to grade, and 3) difference in extent of immersing in computer game according to conditions of computer game usage. A total of 239 children from 1st to 3rd grade in an elementary school in Busan were surveyed with two kinds of questionnaires about usage of and immersion in computer game. The collected data were analyzed using SPSS 12.0 program. It was revealed that the 1st graders showed higher scores on experience of computer game, frequency of computer game per week, and amount of time for each computer game than the 3rd graders. However, there were no significant differences in extent of immersing in computer game according to grade and to conditions of computer game usage. The findings of this study implies that the age of using computer game is going down rapidly. Discussions and suggestions for further study were provided.

The purpose of this study is to analyze connection of the field on 'Nutrition and Food' among grades in the Practical Arts and Home Economics. The subject of analysis is 'Practical Arts' textbook in elementary school and 'Home Economics' textbook in middle school and high school. The Practical Arts textbook of 5th, 6th grade and 5 Home Economics textbooks middle school 1st, 3rd and high school. First of all, it is arranged the aim and contents, used analysis connection frame. The following contents are to summarize the result. First, 'Nutrition and Food' unit is presented nutrition, food, meals management in textbook. Second, aim in curriculum is agreed with contents in curriculum, but how to description in textbook is needed agreements. Third, contents in elementary school and secondary school is connection to develope, but contents in middle and high school are repetition. With the results analyzing connection among text contents, it is concluded that contents' connection has more developed and repeated. Specially, contents of Nutrition are mostly developmental contents, contents of Food are that one part is developmental contents and the other part is repeated contents.

To analyze the design education of elementary school in the united states, the content of Discover art, one of the popular art textbooks for elementary school student, has been examined. Focusing on the developmental stage and sequential curriculum across all grades, design principles, color and criteria of design are investigated. The subjects studied are as follows: an introduction of new word or concept of design principles and color, repetition of the learning, the number of color taught, looking at products of design and making design at each grade level. The curriculum of design principles is well composed, but line, shape and form parts are redundant throughout all grades. The learning order of the color at one grade is well organized but the repetition is too much. The portion of design part is too small. It is adequate that the history of design is introduced at grade 5 where children start to learn history. However, it should be more strengthened for the continuous development of design ability. Looking at product design is introduced before grade 4, and making product design is taught just once at grade 4, although sequential learning is necessary in late elementary grades.

This study analyzed the 2009 revised curriculum 6th grade math geometric domain and developed virtual operation tool contents based RME theory. These materials were examine to find out how to effect on the spatial sense and mathematical attitudes by applying it to teach the 6th grade students. The results were as follows. First, it is more effective for improving spatial sense to study mathematics based RME theory with virtual operation tool contents than normal one. This means that mathematics study based RME theory with virtual operation contents overcomes the limitations of flat learning environment. And it is great educational and effective method for students to improve their spatial sense. Second, it is more effective for improving mathematical attitudes to study mathematics based RME theory with virtual operation tool contents than normal one. This means that Mathematics study based RME theory with virtual operation contents makes student more participate learning actively. It helps the students who have passive learning habits to have self-directed learning habits, ability to cooperation and communicate. The results of this study suggest that mathematics study based RME theory is very helpful for student to improve their spatial sense and have positive effect on self-concept in mathematics, attitudes toward mathematics and improving study habits in mathematical attitudes.

The purpose of this study was to analyze the introduced contents and the nature of science on the history of science in elementary school science textbooks according to the 2009 revised curriculum. For this purpose, first of all, the frequency of contents of history of science in 8 kinds of science textbooks in elementary school is analyzed by grade cluster and content part. Analysis framework for analyzing the introduced contents on the history of science was characterized with three-dimensional combination of the context, the role and the types(Park, Lee, & Lee, 2011). Analysis framework for the nature of science on the history of science was developed by Leite(2002) and revised by Choi (2005) and Kim(2010) and complemented under one expert in science education. The results of this study are as follows: First, the frequency of contents of history of science in textbook is 26 and it were not equally distributed into science textbooks in elementary school as a result of the analysis by grade cluster and content part. Second, with three-dimensional combination framework only 13 kinds were used in all 48 different types through analyzing the textbooks. It implies that ways of introducing contents of history of science into textbooks were limited to certain types. Third, the nature elements of science were not equally distributed on the history of science in elementary school science textbooks. In conclusion, in order to understand the nature of science through the history of science and to foster scientific literacy ultimately, it implicates that it is need to present various kinds of the history of science for one theme in consideration about the grade cluster and content part. Also more multilateral approach is need to introduce equally distributed into textbooks to reflect the elements of the nature of science.

The aim of this study was to analyze the cultural contents represented in elementary school English textbooks for grades 3 and 4 based on the 2015 revised Korean national curriculum. An analysis of cultural contents was conducted on the basis of Morgan(2001)'s five category criteria. Among the five aspects of culture, 'practices' relevant to daily life were presented most frequently in the textbooks followed by 'products'. English textbooks showed a relatively low frequency in 'perspectives' and 'communities' areas of culture. 'Persons' did not appear at all in all eight textbooks. It revealed that there was a serious imbalance in the representation of textbook about cultural contents. In conclusion, there should be balanced cultural contents for the students to have a balanced cultural awareness and to accept cultural diversity and differences. In addition, textbooks should include more various cultural materials and activities for the students to develop four key competencies suggested on the 2015 revised Korean national curriculum.
