The purpose of this study was to investigate the measurement equivalence and to suggest application ways in teaching aptitude and personality test results for pre-service mathematics teachers between a graduate school of education and a college of education. This study analyzed the scores of the teaching aptitude and personality test of 36 pre-service mathematics teachers enrolled in a graduate school of education and 111 pre-service mathematics teachers in a college of education by performing a multivariate generalizability analysis. The main results were as follows. First, graduate's pre-service mathematics teachers had a higher level of teaching aptitude and personality than that of college's pre-service mathematics teachers based on the total scores. In addition, graduate's pre-service mathematics teachers had higher levels of teaching aptitude and personality than those of college's pre-service mathematics teachers except for a creativity application domain based on the sub-domain scores. Second, cognitive domains were measured more precisely but affective domains were measured less precisely for graduate's pre-service mathematics teachers than for college's pre-service mathematics teachers. Third, regardless of school levels, Cronbach's ${\alpha}$ values, which might be overestimated by applying the classical test theory, were higher than dependability coefficients. Fourth, this study showed a somewhat negative result in ensuring the measurement equivalence for a problem solving exploration domain. However, regardless of school levels, this study indicated that the overall measurement was generally reliable on composite scores. Based on these results, it was confirmed that multivariate generalizability methodologies' approach can be useful for exploring the measurement equivalence issues. Finally, this study suggests how to utilize the results of the test, how to apply a multivariate generalizability analysis for detecting the measurement equivalence, and how to develop future research based on limitations.

The purpose of this study was to examine mathematics teachers' perceptions of multicultural education. To achieve this goal, the study explored how 10 elementary mathematics teachers noticed multicultural content in a mathematics textbook. Building upon noticing framework (Jacobs, Lamb, & Philipp, 2010), we first examined teachers' attention toward multicultural content in a mathematics textbook. Then, we examined teachers' interpretation of the content. We employed a content analysis approach to examine the collected data. The results indicated that most mathematics teachers held a content integration perspective. Their view was that "multicultural education" referred to learning about the diverse cultures of different countries. Moreover, although they noticed some multicultural content in the textbook, they wanted to discuss them in superficially descriptive ways and avoid talking about social justice issues. Additionally, some teachers believed that mathematics is a culture-free subject. They argued that multicultural content should not be presented in mathematics textbooks. We also discussed uncommon themes, which were reported by only a few mathematics teachers.

최근 들어, 우리나라에서도 수학 교사의 전문성 신장을 위한 여러 가지 교사 재교육에 관한 관심이 점차 고조되고 구체적인 프로그램의 안이 모색되고 있다. 이에 따라 보다 근원적으로 전문성 있는 예비 교사 양성을 위한 효과적인 교원 양성 체제를 위한 연구 및 개선 방안이 모색되어야 할 것으로 사료된다. 이러한 취지하에, 본 연구에서는 30명의 중등 수학 교사들을 대상으로 설문 조사 방법을 이용하여 사범대학 수학교육과 재학 당시 어떠한 교육 내용이 다뤄졌는지, 또 그러한 교육 내용이 실제 현장에서의 수학 수업과 연관되어 활용되고 있는지 살펴보고자 한다. 그리고 향후 예비 교사 양성을 위하여 사범대학 수학교육과 교육과정에 어떠한 교육 내용이 필요한지를 살펴보고자 한다.

We would like to celebrate the birth of a journal on college mathematics education. We make wishes and hopes on the way of the growth and developments of the journal. We especially emphasize that the journal may provide the streams of knowledges from scholars to students for better accomplishments of college mathematics educations and the development and prosperity of our country, and a storage bank for our own (mathematical) knowledges for the creation of Korea's own mathematical traditions. Best wishes for the journal.

In this paper we give some new characterizations of the intra-regular ordered semigroups in terms of bi-ideals and quasi-ideals, bi-ideals and left ideals, bi-ideals and right ideals of ordered semigroups.

In the present paper, some general convergence principles are established in metric spaces and then theses principles are applied to the convergence of the iterative sequences for approximating fixed points of certain classes of mappings. By virtue of our principles, most of the latest results obtained by several authors can be deduced easily.
