According to the result of PISA and TIMSS, it was reported that interest for Math and Science was far lower compared to high achievement of Them. The purpose of this study is to investigate effects of robot based STEAM education on elementary school students' Math learning behavior and Science motivation. Robot based STEAM education integrated science, mathematics and art with a theme of 'Energy' was practiced for test group and For control group, those three subjects were taught separately in order to achieve this purpose. Curriculum of fourth grade second semester's science, mathematics and art was analysed to teach a robot based STEAM class and STEAM class Model with the theme 'Energy was designed and applied to elementary students. In science class, heat transfer experiment was conducted with robots and the result was related to drawing polygonal lines in mathematics. In art class, robot components were used to describe the heat energy in shapes and colors. The research shows that students' Math learning behavior and Science motivation were improved more with robot based STEAM education than with traditional lessons(p<.05). It proves that robot based STEAM class can be effective for improving interest in elementary Math and Science.

The objective of this study is to analyze the cases related to the lingual and non-lingual metaphors used in the math class at elementary school and consider the values of metaphors as a teaching method for the subject of mathematics. Throughout this study, teachers' gestures are analyzed as lingual and non-lingual metaphors shown between teachers and students in the class for the topic of the inverse proportion in quartic equations for direct and inverse proportions in Chapter 7 for the first semester of the 6th grade at elementary school in terms of the amended curriculum for the year of 2007. According to the results of the analysis, it can be concluded that there are mechanical and hypothetical movement metaphors in the mathematical metaphors observed in this study. Also, in terms of gestures, iconic, metaphoric and deixis gestures are found. Such metaphors seem to be evenly distributed throughout the math class and expressed in various forms. Based on the results of the analysis, the educational meaning given by the utilization of metaphors is considered for the math class.

PISA 2012 showed that while Korean students achieved high-level math achievement in mathematics their levels are relatively lower in math self-efficacy. Students from Singapore, on the other hand, achieved high scores both in math achievement and in math self-efficacy. The results of the two countries differed although both countries has been sharing the same East Asian cultural sphere. This study analyzed the input and the process variables on the student- and school-level concerning math self-efficacy. The results were as follows. In Korea, math interest, instrumental motivation, elaboration strategies, applied and pure math tasks were the student-level variables that affected math self-efficacy. In Singapore, math interest, control strategies, elaboration strategies, applied and pure math tasks were the student-level variables that affected mathematics self-efficacy. Math club, teachers' low expectations were the school-level variables that affected math self-efficacy. For a higher-level of math self-efficacy in Korea, it is important to encourage students not only to use control strategies, but to participate in math clubs. It is equally important for teachers to have higher expectations towards students.

Even though fractions make up one of the most important concepts in the domain of numbers in elementary math, it is difficult to teach or learn them due to their different quantity concepts and notation methods from natural numbers and their various concepts. The didactic transposition of fractions is thus important, and there is a need to examine the didactic concepts of fractions used in the South Korean textbooks for its research. This study compared elementary math textbooks among South Korea, Taiwan, and China and investigated differences in the instructional time and order of fraction concepts in the textbooks according to their didactic concepts and also differences in the instructional methods according to quantitative concepts.

In this paper, the real state of using terms 'product', 'place value', 'nine-nine', and 'numeral' incorrectly or inconsistently in the area in Korean elementary school 1-2 grade math textbooks/workbooks are analyzed. Based on this analysis, the following four conclusions are presented. First, 'Product' should be defined in the ${\ll}$Math 3${\gg}$ textbook like 'sum' and 'difference'. Multiplication is introduced in the ${\ll}$Math 3${\gg}$ textbook/workbook, however, the result of that calculation is not referred to 'product'. Second, there is a need to reconsider the using the term 'place value' in 2nd elementary mathematics. In the ${\ll}$Math 3${\gg}$ and the ${\ll}$Math 4${\gg}$ textbooks/workbooks are not using the term 'place value' clearly. Third, the word 'addition nine-nine table' and 'subtraction nine-nine table' should not be used in the ${\ll}$Math 2${\gg}$ and the ${\ll}$Math 4${\gg}$ textbooks. Using the term 'multiplication nine-nine' and 'multiplication nine-nine table' in elementary school mathematics textbooks/workbooks instead of using the term 'nine-nine' and 'nine-nine table' respectively would be the possible cause of these inaccurate derivatives. Fourth, in 1st and 2nd elementary mathematics 'numeral' and 'number' should be used discriminately. There is a need to reconsider the using the term 'number' uniformly if possible.

The purpose of this study is to understand the public education system in Korea, that features many pre-taught students, and to figure out how elementary school teachers teach them. To accomplish this study, 204 elementary school teachers in Seoul participated in a survey and the frequency and percentage were made. In addition, to add more depth to this study 5 elementary school teachers had several interviews. We obtained the following results. First, elementary school teachers generally think that the situation with many pre-taught students have had a bad effect on public education and pre-taught students are drilled but cannot understand what they have learnt. They also answered that they have low morale when teaching pre-taught students. Second, a large number of elementary school teachers think the situation with many of the pre-taught students does not help the public math education system, which influences the teachers' teaching style. Teachers who answered negative on pre-taught students are running their math classes focusing on understanding math concepts and activities. On the other hand, few teachers who answered positive on pre-taught students did not care about the situation with many pre-taught students.

At the point when textbooks based on storytelling have been used in math classes for elementary first and second grades, this research analyzed any changes in perspectives of in-service teachers towards storytelling education, to promote further application for teaching and learning math by storytelling in the future. 30 in service teachers who have used math textbooks based on storytelling were surveyed in March and in July, 2013. For the better understanding of the survey results, four of the subjects were selected and interviewed. Consequently, teachers' perspectives towards the appropriateness and efficiency of the storytelling education did not change significantly. It also suggested that the most suitable area for storytelling is measurement, the least suitable area is geometry, and storytelling by real-life applications is effective in teaching elementary math.

The purpose of this study were to develop a M-STEAM program for first grades in elementary school and investigate the effects of the program on their learning motivation for the math subject and creative personality. For those purpose, this study set the following research questions. Research Question 1 : How will a M-STEAM program be devised applicable to first grades in elementary school? Research Question 2 : What kind of effect does a M-STEAM program have on the learning motivation and creative personality of students? The findings were as follows: First, lesson contents were reorganized by keeping the Unit 3 in the second semester of first grade in the current math curriculum under the convergence theme of "Build an environment friendly future city" to which the STEAM elements were added. Developed program promoted mathematical thinking ability for problem solving in the process of operating the number of blocks. Through the M-STEAM program, convergence thinking was created from a new perspective by exerting creativity in such process. Second, the STEAM program had effects on the learning motivation and creative personality of first graders in math subject. The t-test results show that the STEAM program developed in this study increased the fun and interest of students, helped with their concentration, and promoted their understanding of mathematical concepts. Therefore the M-STEAM program had positive impacts on the learning motivation and creative personality of first graders in math learning.
