The purpose of this study is to examine the perceptions and needs of the 2015 revised curriculum for elementary school teachers and to draw implications for the application of the 2015 revised mathematics curriculum. For this, the major changes in the 2015 revised mathematics curriculum were examined. Major changes in the 2015 revised mathematics curriculum are as follows: 1) Introduce and emphasize mathematical competencies, 2) Restructure the content system, 3) Reduce mathematics contents to teach, 4) Emphasize the learner's affective domain, 5) Emphasize the use of technology, 6) Improve teaching and learning methods and evaluation methods. Also, a survey was conducted for elementary school teachers to analyze the perceptions and demands of the 2015 Revised Mathematics Curriculum. The contents of the survey are consisted of contents of the teachers' awareness of the main changes of the 2015 Revised Curriculum and their demands to implement the 2015 Revised Curriculum in schools. Finally, conclusions and suggestions were drawn based on the survey results. The conclusions and suggestions are as follows: 1) there is a lack of teachers' awareness of the 2015 Revised Curriculum, 2) Support for mathematics curriculum competencies is needed, 3) A variety of teaching and learning materials are needed for emphasizing the learner's affective domain, using the technology, and improving teaching and learning methods and evaluation methods.

본 연구는 2009개정 교육과정과 2015개정 교육과정을 반영한 교과서에서 연속확률분포를 정의하고 도입하는 방법에 대해 비교 분석하였다. 2015개정 교육과정을 반영한 확률과 통계 교과서는 연속확률변수를 가부번집합인 확률변수로 정의하기보다는 특정 범위의 모든 실숫값을 가지는 확률변수로 정의하였다. 또한 연속확률분포를 도입함에 있어 균등분포를 이용한 방법과 상대도수밀도를 이용한 방법을 사용하였다.

The Korean mathematical curriculum has been changed three times during the resent five years. It led to changes in textbook system. In the 2007 revised mathematics curriculum, workbook was developed focusing on student's self-oriented learning, effective practice in differentiated classroom, and mathematics problem solving considering individual difference. This paper examines the characteristics of the tasks and the way the tasks are organized in the textbooks and the workbook in accordance with the 2007 revised mathematics curriculum; comparing with the function section before and after the amendment. Researchers examine whether the textbook and workbook were accomplished the purpose with "cognitive expectation", "level of cognitive demand", "and "response types". Researchers revised framework of [Son, J. W. & Senk, S. (2010). How reform curricula in the USA and Korea present multiplication and division of fraction. Educ. Stud. Math 74(2), 117-142] to make them suitable for the function section at the seventh grade.

This study investigates the perceptions toward prospective elementary teachers regarding the revised 2015 elementary mathematics curriculum. The aim is to understand the importance and implementation of the revised curriculum and provide implications for curriculum improvement in elementary teacher education institutions, using Interpretative Phenomenological Analysis (IPA). The research findings are as follows: Firstly, prospective elementary teachers perceived that the areas of the revised 2015 elementary mathematics curriculum that require particular focus are number and operations and data and probability. Secondly, they identified the specific elements within these areas that demand dedicated attention as follows: numbers up to four digits in number and operations, mixed calculations with natural numbers, shapes of solid figures, spatial sense of solid figures, comparison of quantities in measurement, etc. These findings can inform the improvement of the curriculum in elementary teacher education institutions.

The study conducted a survey on mathematics teachers' perception about the mathematics curriculum and carried out a field survey of schools' compliance of the 2009 revised mathematics curriculum. The questionnaires were distributed to and collected from 36 mathematics teachers in 22 middle and high schools. According to the results of the study, it was found that most mathematics teachers had low interest in and did not feel the necessity and importance of revising the mathematic curriculum. This was because that the necessity and direction of the curriculum revision was not well understood by secondary school teachers, thanks to a hasty revamping. In addition, schools are organizing and operating their own educational programs with the focus on the college entrance exams, regardless of the guidelines of the current revised curriculum.

본 연구는 유치원 교육과정과 초등 교육과정의 연계성을 강조하는 2015 개정 교육과정 개발 연구가 진행되고 있는 현 시점에서 3~5세 연령별 누리과정과 2009 개정 교육과정에 따른 초등학교 수학과 교육과정의 내용 연계성을 분석하고, 그 결과에 기초하여 연계가 미흡한 내용에 대한 연계성 확보 방안을 제안하는 것을 목적으로 한다. 이를 위해 누리과정 내에서 '수학적 탐구하기'의 위상을 고찰하고, 수학적 내용측면에서 내용 영역의 범주 및 3~5세 누리과정의 수학적 탐구하기의 세부 내용과 초등학교 수학과 교육과정의 1~2학년군 성취기준을 비교 분석하였다. 분석 결과, 각 내용 영역에서 역연계 및 비연계 요소가 파악되었으며, 그에 따른 논의로부터 유치원 교육과정과 초등수학 교육과정의 내용 연계성을 확보하기 위한 시사점을 제안하였다.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through focus group's investigations on the elementary mathematics teacher's guide books. First, We survey previous studies on the teacher's guide books to make the frame of investigation. Next, We compose focus group(8 teachers) for 3~4th grades, and analyze the teacher's guide books according to ready-made frame: compliance of curriculum, accuracy and fairness of contents, selection and organization of contents. As results of investigation, system of organization of the teacher's guide books is needed. Goal, contents, teaching methods, and evaluations have to be consistent in describing mathematical terms. And errors in mathematics and mathematics education are examined more carefully. The teacher's guide books afford teachers many materials and informations to teach mathematics through classroom lessons. So more study on the teacher's guide books and developmental study for the model guidebooks is needed along with the revised curriculum and new textbooks.

Textbooks play a very important role as a medium for implementing curriculum in the school. This study aims to analyze tasks for mathematical competencies in the high school 'mathematics' textbooks based on the 2015 revised mathematics curriculum emphasizing competencies. And our study is based on the following two research question. 1. What is the relationship between core competencies and mathematical competencies? 2. What is the distribution of competencies of tasks for mathematical competencies presented in the textbooks? 3. How does the tasks for mathematical competencies reflect the meaning of the mathematical competencies? For this study, the tasks, marked mathematical competencies, were analyzed by elements of each mathematical competencies based on those concept proposed by basic research for the development of the latest mathematics curriculum. The implications of the study are as follows. First, it is necessary to make efforts to strengthen the connection with core competencies while making the most of characteristics of subject(mathematics). Second, it needs to refine the textbook authorization standards, and it should be utilized as an opportunity to improve the textbook. Third, in order to realize competencies-centered education in the school, there should be development of teaching and learning materials that can be used directly.

Maximum and minimum have a historical background in mathematics and occupy an important part of the differential unit in school mathematics. As the curriculum is revised, there are changes and problems in the way definition introduced. Therefore, this study analyzes the changes in the method of introducing maximum and minimum definitions following the reorganization of the 2007 and 2009 revised mathematics curriculum, and analyzes the differences in maximum and minimum definition methods compared to the nine mathematics II textbooks in the 2015 revised mathematics curriculum and three real analysis. In addition, methods to improve the terms used in relation to the maximum and minimum values are presented.
