Although many people have recognized the importance of history of mathematics in mathematics education, there are few studies that history and mathematics educations are connected. In this paper, we present and discuss the ways of introducing the instruction with mathematics machines. This instruction use the history of mathematics as part of a class not as a tool to stimulate students' interest but as a goal that it can be targeted mathematical itself. To do this, we first analyze the characteristics of applying history of mathematics in mathematical education, second, describe the meaning and the educational value of mathematical machines, and finally explained the way of applying history of mathematics with mathematics machines. The Instruction of history of mathematics with mathematics machines has advantages that practice (manipulation and experiment) and theory (elaboration of definition, production of conjectures and constructions of proofs) are interlaced within a historic-cultural perspective.

콘텐츠 산업의 발전과 인터넷 네트워크의 전 세계적인 확산 및 지속적인 발달로 대학에서의 사이버 수업이 빠르게 확대되고 있다. 따라서, 사이버강의를 형태별로 구분하여 학습자들의 만족도와 환경을 분석하고 효과 측정 및 활성화하기 위한 방안의 연구가 요구된다. 본 연구에서는, 사이버 강의를 강의시수의 일부분만을 사이버로 하는 부분 강의와 강의시수의 모두를 사이버로 하는 완전사이버로 명명하고 구분하여 학습자 만족도 조사를 실시하였으며, 각 사이버 형태의 문제점을 분석하고 이를 활성화하는 방안을 제안하였다.

We define injective and projective representations of a quiver $Q={\bullet}{\rightarrow}{\bullet}{\rightarrow}{\bullet}$. Then we show that a representation $M_1\longrightarrow[50]^{f1}M_2\longrightarrow[50]^{f2}M_3$ of a quiver $Q={\bullet}{\rightarrow}{\bullet}{\rightarrow}{\bullet}$ is projective if and only if each $M_1,\;M_2,\;M_3$ is projective left R-module and $f_1(M_1)$ is a summand of $M_2$ and $f_2(M_2)$ is a summand of $M_3$. And we show that a representation $M_1\longrightarrow[50]^{f1}M_2\longrightarrow[50]^{f2}M_3$ of a quiver $Q={\bullet}{\rightarrow}{\bullet}{\rightarrow}{\bullet}$ is injective if and only if each $M_1,\;M_2,\;M_3$ is injective left R-module and $ker(f_1)$ is a summand of $M_1$ and $ker(f_2)$ is a summand of $M_2$.

The present study examined the cultural competence of university students on migrants and multicultural society in Korea. A total of 11 university students living in Seoul, Gyeonggido and Chungcheondo, were selected for the interview. The participants provided their cultural cognition, cultural knowledge and cultural skill on a variety of issues related to migrants and multicultural society in Korea. Interview results indicated that participants perceived negative and positive affects to Korean society and prejudice about immigrants, thaught economic support as a emergent policy, and didn't experience multicultural society. They wanted to take a trip and learning foreign language. On the cultural skill participants had progressive perspectives about immigrants' right, discrimination and evaluation and had a multiculturism based on assimilation.

This paper concerns with the application of e-based education methodology for people with disabilities targeting to empower them. Instead of the classic educational support such as extended time to take exams, a reader and/or scribe to assist with exams and note taking services, we suggest the use of new pedagogy-the science of educations integrating the state-of-the art. In this paper, we introduce the definition of disabilities for the people who does not fully understand what they means, first, and then possible implementing tools which can empower them with accomplishments. Most of the research in the field of pedagogy has tended to concentrate on the behavioral aspects of instructional sciences. Therefore we would like to point out that we concentrate on the aspects of instructional science particularly related with people with disabilities.

Purpose: The purpose of this study was to identify the latest evidence for interventions involving adolescent newlyweds, and the feasibility of premarital coaching (PMC). Methods: A narrative literature review design carried out through related studies was used for the present literature review. A diverse search from several databases was performed to create a critical appraisal and to develop a more integrated model for the PMC program. Studies that empirical, written in English, peer-reviewed, and published during 2008~2017 were included. Results: Six articles were selected for the review. The principal findings identified three major themes including underage period as a high-risk for marriage, development tasks of the newly married spouse, parenting self-efficacy and the psycho-educational approach of PMC to enhance parenting knowledge, skills, and readiness. Conclusion: It was found that content of PMC as the preparation of underage married couples were formulated based on coaching technic, various spouse and parenting educations, and adjusted based on couples's preferences. Rigorous studies with measurement of long-term retentions are needed.
