Nowadays, open education is popular in Korea. Various open education methods such as open time, open space, open curriculum, team teaching, small group learning are actively introduced into mathematics education. Current 'open education in mathematics' in Korea can be characterized as the application general education reform movement (open education movement) to mathematics education. This movement is interested in teaching methods rather than contents. In this article, I discussed with the limits and the problems of this application and argued that not the method-centered open general education reform movement but the content-centered mathematics education's own reform movement is necessary for the true mathematics education reform.

Many schools of the secondary level have been recently carrying out 'differentiated class'based on ability grouping between classed(DC). They are usually consisted of three levels; high level available to enriched course, middle level, and low level available to supplemental course. Phrhaps, almost all of the schools might nave executed DC before 2000 year. To do this, a lots of teachers have to develop differentiated teaching and learning materials for themselves. But, these mateirals are usually consisted of differentiated mathematics not on 'content'but on 'items'. So, for the successful 7th differentiated curriculum, the issues such as teaching and learning methods, materials, and evaluation system should be considered in depth focused on DC. .Decide issues related to DC(for example, mathematical contents, methods, activities, class speed,extra)based not on teachers or experts but on students. .Differentiate teaching and learning mateirals according to DC and develop the materials(including guidelines, supplementary books, multimedia, extra) based not on mathematical items but on mathematical contents. .Introduce new mathematical concepts or laws using not only not only definition and explanation but also concrete examples or problems. .Suggest differentiated diverse projects related to mathematical subjects suitable to enhance students` thinking ability to each class. .Have students to develop projects successfully by collecting, representing, analyzing, and interpreting data through communications in a cooperative learning environment.

This work aims to investigate mathematics teachers' knowledge and belief on the high school probability and statistics. For this aim, two research questions are estabilished as follows. (1) How is mathematics teachers' knowledge on the main contents of the high school probability and statistics in the 7th mathematics curriculum? (2) What is mathematics teachers' belief on the high school probability and statistics? Survey and interviews were carried out to answer the above research questions. Subjects of the survey were 2 7mathematics teachers who were answered to questionnaire. Among them, 3 volunteers were chosen by provinces for in-depth interview. Research findings in mathematics teacher's knowledge are as follows. Firstly, mathematics teachers do not have much of mathematical knowledge on the newly added and changed contents of the high school probability and statistics in the 7th mathematics curriculum. Secondly, mathematics teachers do not change their teaching-learning method for probability and statistics. Thirdly, many teachers think that the use of technology and reconstruction of the textbooks are required in teaching and learning of the high school probability and statistics. But, they stick on their own way. Research findings in mathematics teachers' belief are as follows. Firstly, many mathematics teachers view the nature of statistics as a branch of the applied mathematics and put the value of high school probability and statistics on the practical usefulness, Secondly, many mathematics teachers think that understanding concepts and improving problem solving ability are the best method of the teaching and learning. Thirdly, many mathematics teachers think that high school probability and statistics textbooks should cause motivations and interests in order not to give up studying probability and statistics. It is expected that the above findings can be used to change teachers' teaching and learning methods and to improve teachers training program.

지금까지의 수학 교구에 대한 연구의 대부분은 연구에서 제시한 교구의 활용을 통하여 나타난 학업성취도의 변화나 수학에 대한 자신감과 태도 등에서 긍정적인 변화에 대한 연구였다. 이에 본 연구에서는 수학 교구 활용에 대한 변화 내용 보다는, 교육과정에서 제시한 성취기준 중에서 교구의 활용에 적합한 성취기준을 조사하여, 그 성취기준에 알맞은 교구의 제시하고, 현재 초등학교 1-2학년군 수학교과서에 제시된 교구를 조사하고 비교하여 앞으로 교구의 활용에 도움이 되도록 하였다. 성취기준에 알맞은 교구는 한국과학창의재단(2017)에서 수학 수업용 교구 표준안에 제시한 교구를 기준으로 앞으로 수학 수업에서 교구의 효과적인 활용에 도움을 주고자 하였다.

현재의 최신 교육과정은 창의적인 인재를 육성하는데 중점을 두고 있다. 하지만 학교에서 실제로 진행되고 있는 수학 교육은 창의성과 거리가 먼 주입식 교육으로 진행되어, 수학을 어렵게 여기는 학생들이 늘어나고 있다. 정부는 이러한 상황을 극복하기 위해 '스토리텔링을 활용한 수학 교육'을 제안하였으며, 이에 게임을 활용한 수학 교육이 다방면에서 연구 개발되고 있다. 그러나 현재 대부분의 교육용 기능성게임들은 연역적 체계를 중시하는 현재의 수학 교육을 탈피하지 못하여, 창의성을 기른다는 목표를 이루지 못하고 있다. 이는 기존의 수학 교육용 기능성 게임들이 수학과목에 대한 목표와 수학 교수 학습이론을 깊이 고찰하지 않았기 때문이다. 따라서 본 연구는 기존의 수학교육이 지닌 주입식 교육의 한계를 넘어서기 위해 수학 교수 학습이론인 RME를 기반이론으로 하여 게임 요소를 활용한 수학적 직관 향상을 위한 초등 기하 교육용 게임 콘텐츠를 개발하는 방법론을 제시하고자 한다.

The purpose of the study is to develop effective teaching methods to strengthen the major learning capabilities of electronic engineering learners through inquiry learning using computing thinking ability. To this end, first, in the electronic engineering curriculum, we performed teaching-learning through an inquiry and learning model related to mathematics, probability, and statistics under the theme of various majors in electronic engineering, focusing on understanding computing thinking skills. Second, an efficient electronic engineering subject inquiry class operation using computing thinking ability was conducted, and electronic engineering-linked education contents based on the components of computer thinking were presented. Third, by conducting a case study on inquiry-style teaching using computing thinking skills in the electronic engineering curriculum, we identified the validity of the teaching method to strengthen major competency. In order to prepare for the 4th Industrial Revolution, by implementing mathematics, probability, statistics-related linkage, and convergence education to foster convergent talent, we tried to present effective electronic engineering major competency enhancement measures and cope with innovative technological changes.

Variable concept plays a crucial role in understanding not only algebra itself but also school mathematics which is algebra-oriented. It solves as an essential means in applying mathematics to the real world because il enables us to describe varying phenomena in the real world. In this study, we examined some matters related to the learning of variable concept in school mathematics. In Particular, we discussed on the teaching of variable concept in the [7-first] stage of the 7th Mathematics Curriculum. We analysed the textbooks in the [7-first] stage and attempted to explain concretely the contents and teaching methods of variable concept which be taught in school mathematics. After reconsidering the practices on variable concept teaching, we pointed out the problems of formalistic teaching method and then proposed the direction in which variable concept teaching should go.

Until now, There have been few studies to investigate a degree of abilities or interesting about mathematical problem-posing of first and second grades in elementary school. This is due to the fact that this students(1st and 2nd grades) have a limited amount of study time and their minds are not fully developed, and are lacking in their representation of ability to use the national language. This being the case, it is difficult to investigate their Mathematical problem-posing in a practical manner. However, our 7th elementary school Mathematics curriculum emphasizes the teaching and learning of Mathematical problem-posing from a basic level of first and second grade with emphasis on activity in teaming Mathematics. Through this study, having analysed the problems those children posed, I have found out they improved in numbers and correctness of their posed problems. And I too could found out showing to their much interesting and confidence to mathematical problem-posing and could confirmed for the children to admit themselves its merits through analyzing some questions to ask their opinions to it. I expect that this study can help to develop the teaching and learning materials for mathematical problem-posing and also to improve its methods of elementary school mathematics. The next study task is, I think, that it is necessary to accumulate the studies to investigate and analyse the practical learning activities of children for problem-posing contents of mathematics text books.

수학 수업에서 요구되는 교사 지식을 '교과 내용 지식', '학습자 이해 지식', '교수 학습 방법 및 평가 지식', '수업 상황 지식'으로 상정하고, 수업 평가 및 교사 지식과 관련된 여러 선행 연구들에 의거하여 본 연구자는 교사 지식 요소 각각에 대한 수업 평가 영역 및 기준 마련을 위한 연구를 수행해 왔다. 본고에서는 지금껏 본인에 의해 수차례 수행된 연구 결과들을 신중히 재검토하여 보다 일관성 있고 체계적으로 수정 보완하고자 하였다. 이때, 각각의 교사 지식에 대한 교사 자신의 자기평가 방법에 따라 측정 용이한, 즉 실제적 활용 가치를 신중히 고려함은 물론, 특히 '수업전', '수업 중', '수업 후'의 상황을 모두 반영한 수학 수업 평가 기준을 새로이 마련하고자 하는데 중점을 두었다. 이처럼, 본고의 연구 결과를 활용하는데 있어서 교사는 수업 전, 수업 중, 수업 후 상황에 국면하게 되고, 교사 지식은 이러한 상황 모두에 요구되나, 실제의 수업 상황에서 모든 교사 지식에 대한 수업 평가 기준을 '동시에' 모두 고려하여 평가, 진단하는 것은 쉽지 않을 일이다. 이에 따라, 교사 자신 및 동료들이 해당 수업에 따라 요구되는 특정의 교사 지식 및 특정의 수업 진행 상황(수업 전, 수업 중, 또는 수업 후)을 선정하여 이에 국한, 집중하여 평가하도록 해야 할 것이다.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through survey data and focus group interview on structures of textbooks. First, We collect online survey results which 2333 elementary school teachers participated. Next, We interview focus group(8 teachers) about shapes of textbooks, quantity of learning contents, activities and problems for evaluation in the mathematics lessons. Storytelling is especially issued in the 2009 revised mathematics curriculum. We intensively discuss learning and teaching methods with application of storytelling textbooks; interests of students, role of storytelling textbooks etc. As results of analysis, the positive rate to use the 2009 revised textbooks is relatively high about shapes and activities of textbooks. But there is more considered about storytelling method. Storytelling may be positive on improvement of learning interests and participation of students. In order to develop these advantages, studies in relation of storytelling are more proceeded and teaching materials for teachers are required effectively in order to applicate to the elementary school.
