In the history of elementary school mathematics education in Korea, the period led by the Government-General of Joseon during the Japanese colonial period cannot be omitted. As a way to grasp the real state of elementary school mathematics education at that time, there is a method of analyzing elementary school mathematics textbooks published by the Government-General of Joseon. However, the actual state of the publication of them was not sufficiently known. For this reason, this study surveys the actual state of the publication of those textbooks. To this end, real information on textbooks owned currently by various institutions and information on the publication of those textbooks in the official gazette and documents of the Government-General of Joseon were checked and organized.

The purpose of this study is to analyse the effects on the academic achievement and learning motive in mathematics class by use of Cornell-note method at an elementary school. Thus, Cornell-mathematic note is designed for the experiment in order to recognize the effects how the Cornell-note influences students' mathematics academic achievement and learning motive. This experiment was carried out for 13 weeks and the target was 28 students. The group was consisted of 6rd grade students in elementary school located in Busan. To see the effects of Cornell-note method after experiment, post-test was carried out about mathematics academic achievement and learning motive. The results of this study are as follows: There was meaningful difference before and after test about mathematics academic achievement and learning motive. The academic achievement and learning motive in mathematics were improved after Cornell-note applied. Improvement of learning motive caused progress of academic achievement in mathematics class. The Cornell-note way is not appropriate, however, to reinforce mathematical communication ability and to attract students' interest. Therefore, systematic symbol is necessary and consider about adoption of story-telling way.

The purpose of this study was to investigation the elementary school teachers' perception in STEAM(Science, Technology, Engineering, Arts, Mathematics) Education. For this study, 93 elementary school teachers who have taught mathematics/science in gifted class were selected and a fifteen items questionnaire designed to elicit teachers' perception of steam education was to administered to them. The major findings are as follows: First, the ratio of teachers who understood a steam education exactly is very low. But teachers have positive thoughts about the need of steam education. Second, teachers thought that steam education has a good effect on elementary education. Third, teachers thought that steam education will be an alternative teaching and learning method. Fourth, teachers have negative thoughts to participate in class work related on steam education. To improve negative attitudes on steam education, incentives for teachers seems to be required. In order to spread steam education among the elementary school teachers successfully, the expansion of school facilities, administrators and staff in mind, improving financial support, strengthening education through the development of content and teaching strategies were analyzed as a challenge.

Open education is carried out and studied in both phases of theory and practice in Korean elementary schools in these days. 1 introduced three open teaching and learning methods which we can use practically in elementary school mathematics education. They are the teaching and learning by open-end-approach, From problems to problems and Problem posing. First, I illustrate each meaning of three teaching and learning methods. Next, I presented the concrete plans of each teaching and learning method, and exhibited some examples of students' own works.

We study on intuitive verification and rigor proof which are in geometry of Korean and Russian $7\~8$ grade's mathematics textbooks. We compare contents of mathematics textbooks of Korea and Russia laying stress on geometry. We extract 4 proposition explained in Korean mathematics textbooks by intuitive verification, analyze these verification method, and compare these with rigor proof in Russian mathematics textbooks.

In this paper, we present a new extended Jacobi method for computing eigenvalues and eigenvectors of Hermitian matrices which does not use any complex arithmetics. This method can be readily applied to skew-Hermitian and real skew-symmetric matrices as well. An example illustrating its computational efficiency is given.

In this paper we present a method of circular arc approximation by quartic B$\acute{e}$zier curve. Our quartic approximation method has a smaller error than previous quartic approximation methods due to the alternation of the error function of our quartic approximation. Our method yields a closed form of error so that subdivision algorithm is available, and curvature-continuous quartic spline under the subdivision of circular arc with equal-length until error is less than tolerance. We illustrate our method by some numerical examples.

We obtained sufficient conditions for $\phi$(t)-stability and uniform $\phi$(t)-stability of the trivial solution of comparison differential system. we also investigated the corresponding stability concepts of the trivial solution of the differential system using the thoery of differential inequlities through cones and the method of conevalued Lyapunov functions.

This study examined the effect of coaching based on private tutoring on students' learning ability and academic achievement in university mathematics education. Those in the coaching group showed statistical significance in academic achievement compared to those in the non-coaching group. In addition, the coaching was found to be more effective for those with poor academic performance or women than those with excellent academic performance or men respectively. Due to limitations on survey time and number of respondents, it is difficult to draw a general conclusion about the effect of coaching in university mathematics education. Still, it is significant that the study applies coaching as a method to teach students university mathematics for the first time and the results are in consistent with those of previous studies on other subjects.

In this paper we briefly survey recent works on training of mathematics teacher at universities of some countries. The main purpose of this work is to propose a desirable direction of curriculum and teaching/learning paradigm for training mathematics teachers at universities.
