본 연구의 목적은 활동 이론의 관점에서 초등학교 예비교사인 김교사가 실시한 수학 수업을 탐색하는 것이다. 본 연구에서는 $Engestr{\ddot{o}}m$이 제안한 활동 이론(Activity theory)과 활동체계(Activity system)의 주요 개념인 주체, 목표, 도구, 공동체, 분업, 규칙의 측면에서 수학 수업과 수학 수업에서 나타난 현상을 살펴보았다. 본 연구의 결과로서, 활동체계로서의 김교사의 수학 수업에서 목표와 도구의 동요, 목표-규칙-결과-학생 주체 사이에서 발생하는 '다층-목소리'와 갈등, 분업-공동체-규칙 사이에 내재하는 불협화음 등의 현상이 발생함을 논의하였다. 또한, 본 연구에서는 김교사의 수업에서 수학과 교육과정의 강조점인 조작 교구를 활용한 수학 원리의 이해가 활동체계의 규칙으로 작용함을 확인했으며, 이러한 규칙이 수학 수업에서 구현되기 위해서는 공동체의 노력과 정책적 지원이 필요함을 제안하였다.

This paper presents an approach for using right-truncated exponentially distributed random variables to model activity times in stochastic activity networks. The advantages of using the right-truncated exponential distribution are discussed. The moments of a project completion time using the proposed distribution are derived and compared with other estimated moments in literature.

본 논문에서는 제7차 교육과정의 특색중의 하나인 교과재량활동시간의 효율적 운영에 관하여 연구하였다. 교과재량 활동시간에 '함께가자! 우리' 프로그램의 운영을 통하여 다양한 수학에 대한 경험, 실생활을 소재로 한 수학문제, 수준별 협동학습 수학에 대한 흥미를 유발시켰으며, 1:1 맞춤학습에 의한 부담 없는 질문과 학습의 분위기 조성 등이 학생들의 자기주도적 학습력을 향상시키는데 많은 도움을 주었음을 알 수 있다.

School Math Field Trips(SMFT) for School Mathematics can be defined as teaching and learning activity of mathematics going into the field of Korean history, culture, science and technology. This is a literature analysis study to systemize teaching and learning method of mathematics based on literature analysis and real SMFT activity. First, SMFT was introduced to improve cognitive affective and cultural-mathematical teaching and learning method of mathematics. Second, SMFT has three purposes of cognitive, affective and cultural-mathematical. Third, to conduct mathematical education activity the direction of teaching was set. Forth, the progressing way of developing material and SMFT was researched. Fifth, developing the evaluation standard of SMFT and evaluation method was suggested.

After entering an elementary school, in fact, a number of children regard mathematics as one of very difficult subjects because of its abstractiveness. This is caused by the fact that their basic thinking power is not yet formed or they can not understand the special quality of mathematics. So this article emphasizes the need to build up the higher logical thought and a basic mathematical concept at the lower grade elementary school stage in which the loaming activity on mathematics begins in earnest, that is, at the stage before having an experience on the calculating activity using numbers. But at present the lower grade elementary school students in our country do not understand the special quality of mathematics composed of a various symbolic system and lay stress upon mathematics learning attached to the calculative activity. In order to make the right mathematical concept of the lower grade elementary school, the basic knowledge and ability as follows is sure to be formed. 1) the foundational logical manipulation activity and knowledge 2) the using ability of the sign and symbolic system At the stage on which mathematics learning activity begins, it is a very important task to make the right concept of the abstractive math and nurse the capability for finding mathematical relations covered under the sign system through the continuos loaming activity on . Through the basic logical manipulation activity and the game activity of sign for lower grade elementary school students mentioned in this article, they can not only foster the higher level logical thinking power and the foundational calculative ability but also bring up the interest on the activity of establishing a new problem solving strategy.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.
