This study investigated the perception and utilization about computer of beginning secondary mathematics teachers by utilization frequency of computer. To increase utilization frequency of computer in school mathematics, our finding shows that beginning secondary mathematics teachers should have an interest in computer utilization and perceive computers as an important tool for mathematics learning. In addition, they are likely to use more frequently computer under the condition that computers have sufficient class materials and supplement their shortcomings that have derived less usage in math classes. Therefore, future studies have to investigate not only how to develope textbooks and run after-school classes but also how to make creative discretional activities by computer, which makes computers more useful for teacher training. In sum, the results of case studies for computer usability should be released to motivate computer utilization and increase mathematical thinking ability.

본 연구에서는 수학성취도에서의 불평등도를 모색하였다. 구체적으로 경제적인 불평등도로서 널리 사용하는 지니계수를 활용하여 학업성취에서의 불평등도를 계산하였고, 불평등성에 대한 언어적 해석의 기준을 마련하였다. 자료 분석 결과는 농촌지역보다는 중소도시, 중소도시보다는 대도시, 대도시의 일반고 보다는 과학 고등학교에서의 불평등도가 약하게 나타났다.

This study aimed to investigate and compare perceptions of middle and high school mathematics teachers on assessment. For the purpose, we developed and used a survey consisting of two parts(importance/performance on assessment and general opinion on process-based assessment). We gathered data from 188 middle school and 125 high school mathematics teachers in Incheon area. An Importance-Performance Analysis(IPA) method was used for data analysis. As results, middle school mathematics teachers showed higher perception on both importance and performance in almost all area on assessment than high school teachers. In addition, research results based on teaching experience indicated that mathematics teachers having more teaching experience seemed to perceive high importance-high performance and low importance-low performance tasks more than mathematics teachers having less experience. In particular, middle school teachers recognized many low importance-high performance tasks according to their teaching experience. The IPA gave us different results depending on the school size. The larger the school, the more diverse opinions appeared tasks in low importance-high performance. From the general opinion on process-based assessment, the middle school mathematics teachers also seemed to have more positive perspectives and to be more active in assessment than high school mathematics teachers. Finally, we discuss implications for future policy formulation and implementation on process-based assessment.

According to TIMSS, secondary math teachers in Korea has lower confidence compare to other countries, despite the fact that teachers' confidence of teaching is an important variable. This not only influences the student's improvement but, also the quality improvement of teachers' career. Therefore, this study explores the effect of secondary math teachers' confidence according to the context variables such as teaching years, teaching preparation, collaboration with other teachers, and teaching limitation. Additionally, these context variables' $R^2$ toward the change of teaching confidence is also included. Results indicate that teaching preparation, collaboration with other teachers, and teaching limitation contribute in the confidence of teaching. $R^2$ of the change of teaching confidence shows large contribution to teaching preparation which does not accomplish with other variables.

The purposes of this study are to confirm the standard of ethical judgement ability of the mathematically gifted students and examine which factor makes on the ethical judgement ability among the mathematically behavior characteristics. For it, correlation analysis and regression analysis between the two things were conducted with SPSS 12.0 based on the results of mathematically behavior characteristic inspection and ethical judgement ability inspection. Also, the interview was conducted for students whose KDIT score is the highest and the results were intended to apply the results as the material supporting the results of qualitative test results. The interview with students examined which mathematically behavior characteristic factor made an effect on his own ethical judgement ability through the structural questionnaires.

수학사는 수학적 사실이나 수학자에 대한 연대기적 나열만을 의미하는 것은 아니다. 수학사에서는 수학적 개념들, 정리들, 연구 방법의 발생, 축적, 그리고 발전에 대한 폭넓은 견해를 접할 수 있다. 특히, 수학사에서 접할 수 있는 수학 문제해결의 다양한 방법은 수학 교수-학습 과정에서 교사의 올바른 교수학적 선택을 위한 중요한 기초 자료가 될 수 있다. 본 연구에서는 그리스의 수학자 아르키메데스가 구의 부피를 구하기 위해 사용했던 공학적 문제해결 방법을 살펴보고, 공학적 방법의 활용에 관련된 수학적 기초를 살펴보고, 공학적 문제해결 방법을 중등학교 수학 영재교육에 활용할 수 있는 가능성을 모색할 것이다.

In this paper, we examine how secondary school mathematics textbooks on calculus introduce the history of calculus. In order to identify the problem, we consider the Babylonian integration by trapezoidal rule, which was made to calculate the location of Jupiter in 350-50 B.C., and the integration by the method of the rotating plate of ibn al-Haytham in Egypt, about 1000 years. In conclusion, our secondary school mathematics textbooks describe Newton and Leibniz as inventing calculus and place their roots in ancient Greece. The origin of the calculus is in Babylonia and the Faṭimah Dynasty (909-1171) (Egypt) and it is desirable that the calculus is developed in Europe after the development of the power series in India, and that the value of Asia Africa is introduced in the textbooks.

The east-asian mathematics is highly evaluated in mathematics education. In this paper, we search the geometric problems of east-asian mathematics in high school textbooks and various examinations and investigate how to use such problems. We also confirm that the geometric problems of east-asian mathematics can be widely used as real life materials for introducing new mathematical topics, real life applications for mathematical topics, and valuable source for mathematical discourse.

This study aims at what is required knowledge and ability to pre-service math teachers in teacher certificate examination. First, the items are analyzed and among questions of discipline of mathematics education in the last five years are analyzed and classified. Second, an analytical framework suitable for item analysis is examined and the items are analysed by the analytical framework. Finally, helpful implications for discipline of mathematics education assessment can be drawn from this study. It is found that the discipline of mathematics education assessment has the following characteristics: 1) It assesses specific content of the assessment component; 2) It assesses a teacher's theoretical knowledge, practical knowledge and creative knowledge in terms of teaching ability; 3) There are six cognitive assessments; 4) There is an item for difficulty adjustment.

The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.
