In this thesis, we designed a experimental learning-teaching plan of 'decimal fraction concept' at the 4-th grade level. We rest our plan on two basic premises. One is the fact that a essential concept of decimal fraction is 'polynomial of which indeterminate is 10', and another is the fact that the origin of decimal fraction is successive measurement activities which improving accuracy through decimal partition of measuring unit. The main features of our experimental learning-teaching plan is as follows. Firstly, students can experience a operation which generate decimal unit system through decimal partitioning of measuring unit. Secondly, the decimal fraction expansion will be initially introduced and the complete representation of decimal fraction according to positional notation will follow. Thirdly, such various interpretations of decimal fraction as 3.751m, 3m+7dm+5cm+1mm, $(3+\frac{7}{10}+\frac{5}{100}+\frac{1}{1000})m$ and $\frac{3751}{1000}m$ will be handled. Fourthly, decimal fraction will not be introduced with 'unit decimal fraction' such as 0.1, 0.01, 0.001, ${\cdots}$ but with 'natural number+decimal fraction' such as 2.345. Fifthly, we arranged a numeration activity ruled by random unit system previous to formal representation ruled by decimal positional notation. A experimental learning-teaching plan which presented in this thesis must be examined through teaching experiment. It is necessary to successive research for this task.

This study analyzed the TV documentary titled on early childhood English education through narrative structure analysis (Chatman, 2003). It performed syntagmatic analysis to clarify the story structure with a focus on the development of events, and paradigmatic analysis to understand the semantic structure hidden in the text by binary opposition analysis. The documentary was constructed in the frame of 'balance-confusion-rebalance', and it was explicitly delivered that the English immersion education prohibited in the private elementary schools has stimulated the market of private English education. However, the government's and students' voices were missing, and the group of parents, private elementary school officials, and people involved in private English institutes played as main agents to lead the discourse of English immersion and early childhood English education in the documentary.

The purpose of this study was to analyze future student competency based elementary Korean language classes to examine how they can be combined with current classes based on achievement criterion. Focus Group Interviews (FGI) were conducted with elementary teachers to find current lesson plans and design strategies, and to analyze their perception of future student competency proposed by Ministry of Education. After competency based lesson design was combined with regular class and implemented, teachers were finally interviewed for feedback of the classes. This study found problem issues such as conception of core competencies, gap between student achievement and competency accomplishment, student evaluation system as well as administrative support for execution. This study concluded that teacher training and systematic support should be enforced to ensure teachers competencies before demanding strategically.

This research is about storytelling in middle school geometry. This study is basic research about actualizing mathematical teaching and learning based on storytelling that is raised for reforming school mathematics education. In order to develop the mathematics textbook model, development of procedures and methods were extracted from the literature. And mathematics textbook model were developed in accordance with the process and methods. Examples are presented in terms of the development of material with 'story as a communication tool', 'familiar story as a script' 'universality of the world or simulation of life as a story', 'story as a means to foster creativity: story making'. Through the results of this study, we are also able to check the possibility of storytelling in mathematics class. And this study will be the foundation for teaching and learning using storytelling.

The processes of mathematics development and the results of it are always those of making a conquest of the circumscription by historical inevitability within the historical circumscription. It is in this article that I try to show this processes through the history of calculus. This article develops on the basis of the dialectical materialism. It views the change and development as the facts that take place not by individual subjective judgments but by social-historical material conditions as the first conditions. The dialectical materialism is appropriate for explaining calculus treated in full-scale during the 17th century, passing over ahistorical vacuum after Archimedes about B.C. 4th century. It is also appropriate for explaining such facts as frequent simultaneous discoveries observed in the process of the development of calculus. 1 try to show that mathematics is social-historical products, neither the development of the logically formal symbols nor the invention by subjectivity. By this, I hope to furnish philosophical bases on the discussion that mathematics teaching-learning must start from the real world.

In education, evaluation is an important element because instructor can judge the growth and development of students, it has been to bring about quality improvement in education. Performance assessment has emerged to overcome traditional evaluation such as paper test, multiple choice test. Performance assessment is an approach to measuring a student's status based on the way the student completes a specified task. Information literacy instruction is aimed at cultivating information literacy. Performance assessment suitable for measurement to status of Information literacy. In order to performance assessment, task should have the first. However, instructor is difficult to develop a good performance task to meet the assessment needs. Therefore, this research aims at suggesting the developmental tool of performance task applicable to Information literacy instruction. The proposed tool is a template type, consists of 4 steps, educational goals and learning objectives, knowledge and capabilities, task types, measurement and scoring criteria.

by A.C. Clairaut was written based on the historico-genetic principle such as his . In this paper, by analyzing his we can induce six principles that Clairaut adopted to teach algebra: necessity and curiosity as a motive of studying algebra, harmony of discovery and proof, complementarity of generalization and specialization, connection of knowledge to be learned with already known facts, semantic approaches to procedural knowledge of mathematics, reversible approach. These can be considered as strategies for teaching algebra accorded with beginner's mind. Some of them correspond with characteristics of , but the others are unique in the domain of algebra. And by comparing Clairaut's approaches with school algebra, we discuss about some mathematical subjects: setting equations in relation to problem situations, operations and signs of letters, rule of signs in multiplication, solving quadratic equations, and general relationship between roots and coefficients of equations.

The purpose of this study was to examine the Pedagogical Content Knowledge(PCK) of teachers and their educational practice in the category of plane figure, to make a comparative analysis of their PCK and educational practice, and to discuss the relationship between their PCK and the characteristics of their instruction. Instruction of four selected elementary school teachers was analyzed to find out their educational practice. In conclusion, the characteristics of the PCK and actual instruction of the teachers could be listed as below: First, as a result of comparing their PCK and educational practice on plane figure by applying selected analysis criteria, there was a close correlation between their PCK and actual instruction. Second, the teachers had various levels of PCK on different areas. Especially, there was a large disparity in mathematical content knowledge and knowledge of teaching methods. Third, the teachers who had plenty of PCK were more excellent in textbook reconstructing, and those who fell behind in terms of PCK were more reliant on textbooks as if the textbooks had been the Bible.

중등 교육의 질을 확보하기 위한 가장 핵심적인 변인은 교사이며 교사의 자질 향상과 전문성 개발은 교육에 있어 중요한 화두이다. 교사의 전문성은 무엇보다도 교사의 가르치는 능력에서 확보되어야 하며 교과 내용 지식의 확보가 이를 위한 첫걸음이라고 할 수 있다. 본 연구에서는 수업과 심층면담에서 드러나는 초임 교사의 내용 지식(knowledge), 실천 행위(practice), 의미 이해 전략(sense-making strategy)을 분석하여 교사의 과학 내용에 대한 전문성을 파악하는 것을 목적으로 한다. 이를 위해 수도권의 중등학교에서 근무하는 여섯 명의 중등 초임 과학교사를 대상으로 각각 두 차례의 수업 관찰과 구조화된 면담, 한 차례의 우선순위 면담을 실시하였으며, 미시건 주립대학의 Knowles팀에서 개발한 분석틀을 사용하여 질적으로 분석하였다. 본 연구의 결과는 다음과 같다. 첫째, 초임 교사들은 그들이 지향하는 교사상에 따라 과학 교수 활동에 대해 다양한 의도를 가지고 있었으며 비전공 교과의 과학 내용 지식에 대해서는 다소 어려움을 표현하고 있었다. 둘째, 연구에 참여한 교사들은 대체로 교과서에 의존하여 교육과정에서 제시한 내용과 교과서에 제시된 지도 방법에 크게 의존하여 수업을 진행하고 있었으며 교과서 수준의 개념을 중심으로 나열하는 방식을 주로 사용하였다. 다만, 교사가 스스로 재구성한 내용을 바탕으로 자신의 내러티브로 이끌어가려는 시도가 드러나기도 하였다. 셋째, 학생들의 내용 이해를 돕기 위하여 중요한 과학적 개념을 강조하고 그러한 개념을 반복하는 전략을 주로 사용하였다. 그러나 일부 초임 교사의 사례에서는 적절한 비유와 예시를 도입하려는 시도가 발견되기도 하였다. 한편, 연구에 참여한 초임 교사들은 모두 전문성 개발을 위한 노력이 필요하다고 인식하였으며 교사 양성 과정에서 교직과 관련하여 실제적인 도움을 줄 수 있는 프로그램 개발의 필요성을 주장하였다.주로 나타났으며 우리나라 교육과정수업에서는 DC-DP DP-AD맥락의 반성적 탐구가 나타났다. 정리활동에서 우리나라 교육과정은 반성적 교육과정보다 자료 맥락의 영역개념을 더 자주 이용하고 다양한 맥락의 반성적 탐구가 나오고 있으며, 이는 우리나라 교육과정의 학습지의 활동이나 문제는 학생들에게 익숙하고, 자료 패턴을 가지고 행동결정으로 연결짓는 활동이 명확히 제시되었기 때문이라고 판단된다. 두 그룹의 상호작용 특징에 따른 반성적 탐구의 성향의 차이는 도입단계에서 그룹의 특징과 상관없이 A-AD, AD-SR맥락의 반성적 탐구가 나왔으며 전개와 정리단계에서는 N그룹에서는 DP와 관련된 의미 있는 반성적 탐구가 나오는 반면 M그룹에서는 이러한 맥락의 반성적 탐구는 아주 드물게 나타나며, GN과 관련된 행동결정이 자주 보이고 있었다. 정리활동시 주로 하는 기록 활동에서 N그룹에서는 다양한 맥락에서 반성적 탐구를 하고 있는 것에 비해 비교 그룹에서는 서로 견제하고 확인하는 상호작용의 특징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.지역산업 발전을 위한 기술역량이 강화될 것이다.정 ${\rightarrow}$ 분배 ${\rightarrow}$ 최대다수의 최
