본 연구는 교사양성 대학에 적합한 현대대수학 강좌운영의 실례를 소개하고자 한다. 이를 위하여 군, 환, 벡터공간 내용을 적절히 재구성한다. 갈로아 정리는 고차방정식 근의 가해성과 밀접한 관련이 있으므로 중 ${\cdot}$ 고등학교육과정과도 관련지을 수 있다. 그러나 근론과 환룐, 벡터공간의 이론적 배경을 바탕으로 체론의 갈로아 정리로 나아가는 과정에서 많은 학생들이 어려움을 토로하는 것이 현실이다. 이처럼 그 내용의 중요성에 비해 실질적인 접근의 어려움으로 인하여 체론을 아예 배우지 않거나 배우더라도 그 본질을 이해하지 못하는 경우가 많다. 따라서 본 연구에서는, 교사양성 대학의 학생들의 갈로아 정리의 핵심과 본질을 보다 쉽게 이해할 수 있도록 함에 초점을 두고자 한다.

In this study, we identified the effects of Self-Reflective Note(SRN) strategy, which used on 'college mathematics' courses, operated as a liberal arts curriculum course in university. For this purpose, we used SRN strategy on 'college mathematics' 3 classes, 'college mathematicsII' 1 class enrolled 95 students, and then analyzed the data. For identifying a change of students' learning, we conducted surveys related to the affective domain, core competencies, satisfaction. From this, we identified the followings. First, the interest, self-confidence, future expectation of students who attended classes in which SRN strategy is used are positively changed. Second, core competencies(self-directed ability, communication ability) of students who attended classes in which SRN strategy is used are improved. Third, the students who attended classes in which SRN strategy is used evaluated such as mathematics learning using the strategy help their mathematics study. Fourth, the students who attended classes in which SRN strategy is used evaluated such as the strategy improved their learning habit, supplemented their weakness, and activate realistic communication between professor and them.

Despite the recent increased attention to mathematics teacher education there have been lack of empirical studies on how to teach teachers. A study of mathematics instruction for prospective teachers can be conducted either by a teacher educator's critical reflection on her teaching or by observation of others' teaching practices. This paper was from the author's observation of a mathematics instruction course for future elementary teachers at the University of California at Irvine. As such this paper described in detail how the course was implemented throughout the quarter and drew implications for a teacher preparation program in Korea. As the course had a specific purpose of promoting future teachers' expertise in mathematics instruction and employed various strategies that were different from a typical university course, this paper is expected to provide teacher educators with the insight of an alternative teaching style and to provoke discussion of how to connect theory to practice for effective teacher education.

Inventive mathematical thinking, original mathematical problem solving ability, mathematical invention and so on are core concepts, which must be emphasized in all branches of mathematical education. In particular, Polya(1981) insisted that inventive thinking must be emphasized in a suitable level of university mathematical courses. In this paper, the author considered two cases of inventive problem solving ability shown by his many students via real analysis courses. The first case is about the proof of the problem "what is the derived set of the integers Z?" Nearly all books on mathematical analysis sent the question without the proof but some books said that the answer is "empty". Only one book written by Noh, Y. S.(2006) showed the proof by using the definition of accumulation points. But the proof process has some mistakes. But our student Kang, D. S. showed the perfect proof by using The Completeness Axiom, which is very useful in mathematical analysis. The second case is to show the infinite countability of NxN, which is shown by informal proof in many mathematical analysis books with formal proofs. Some students who argued the informal proof as an unreasonable proof were asked to join with us in finding the one-to-one correspondences between NxN and N. Many students worked hard and find two singled-valued mappings and one set-valued mapping covering eight diagrams in the paper. The problems are not easy and the proofs are a little complicated. All the proofs shown in this paper are original and right, so the proofs are deserving of inventive mathematical thoughts, original mathematical problem solving abilities and mathematical inventions. From the inventive proofs of his students, the author confirmed that any students can develope their mathematical abilities by their professors' encouragements.

한국의 대학수학 교육에 대한 여러 종류의 관심이 다양한 현실적 필요성에서 대학의 수학 교수들 사이에서 일고 있다. 대학수학 교육의 어떤 연구 주제를 누가 어디에서 어떻게 연구하여야 연구로서 가치, 타당성 그리고 연구 결과를 유용하게 활용할 수 있는지 등 연구의 방향, 목표, 그리고 결과의 활용에 대한 적절한 합리적 준거틀에 대한 논의가 부족한 실정이다. 일반적으로 수학교육에 대한 연구 결과는 실제 수학 수업을 수행하는 교수, 교사 또는 교육행정가에게 유용한 정보, 지식 그리고 수업 수행 방법(기술) 등을 제공하여 그들의 의사결정 문제를 결정하도록 적절한 도움을 줄 수 있는 유용성을 가져야 한다. 학교수학 교육은 국가적 교육과정을 갖고 있다 이에 비하여 대학수학 교육은 각 대학마다 다른 교육 환경과 목표를 반영한 대학교육과정에 대학수학 관련 교과(강좌) 또는 수학전공 교과들이 포함되어있다. 다양한 대학교육 환경과 시스템에 놓여있는 대학수학 교육의 상황 또는 현상을 개선하기 위한 연구의 수행 원칙과 질적 기준들 무엇인가?를 논하였다.

The main purpose of this work is to suggest a new approach to teaching general topology to undergraduate students. First, we change the order of contents. Usually, we introduce definitions, examples, theorems, and problems in this order. But, showing familiar examples of some concept of topology prior to the definition of one is the best method so far as I know from teaching experience of topology, which students feel very hard because of its abstractness. For more efficiency, mathematics-clubs each consisting of three or four students in topology course are established. This makes students very positive in topology class.

The main purpose of this work is to propose programs of calculus for the department of mathematics education of teacher training universities. There is a description of the characteristics, goal and contents of calculus course for pre-service teacher, followed by principles for teaching the subject. We suggest the constituents and something being kept in mind for each part in calculus.
