This study is to identify and analyze the realities and the problems of the open education in mathematics, and suggest the directions of the open education in mathematics. I have examined 104 primary school teachers using the questionnaire, observed and analyzed two open instructions. The advocates for open education should try to establish its identities. I claim that the open education in mathematics should be opening children's thinking. And I propose some suggestions for such instruction.

The study aimed to provide a proposed conception of technical solutions to address the educational loss in mathematics in the fifth grade of primary school, and the study adopted the descriptive approach. male and female teachers, and to achieve the study objective, the researcher built a tool for the study, a "questionnaire", in which he used the comprehensive inventory method, and the results of the study showed: identifying the learning outcomes that represent an educational loss, and identifying the learning outcomes that are considered essential in teaching and learning mathematics for the fifth grade of primary school. In the event that it is not achieved by students, it is considered an educational loss that may affect the future of students' education and learning. Because it is a basis for later experiences in mathematics in other classes, and the study also found the effectiveness of the proposed visualization of technical solutions provided to address the educational loss in mathematics for the fifth grade: (short electronic tests, YouTube channel, homework, educational platform, electronic worksheets, and communication channels).

The purposes of this study were to investigate the practice of performance assessment in elementary mathematics classes especially focused on 4th grade. To achieve this, three research questions were posed as follow: First, What do they prepare for performance assessment? Second, What kinds of tests do they use in mathematics performance assessment? Third, What kinds of difficulties do they have for performance assessment and what should be changed for a successful performance assessment in mathematics? To Answer the research questions, three 4th grade classes were selected from three different elementary schools in seoul and three teachers were interviewed. From the data analysis, several conclusion were drawn. First, a plan for mathematics performance assessment was not set by the class teacher who are in charge of the class. The main reason was lack of time. Second, in most of the assessment, written tests were used and the items in the tests were skill-oriented. Third, teachers thought that performance assessment was needed in mathematics. But lack of their time, knowledge and competency, it is difficult to do performance assessment in mathematics.

Mathematical Problem solving has been the focus of a considerable amount of research over past 30 years. But nowadays problem solving is being beginning to be of less interest to mathematics education researchers. Moreover, mathematics teachers have an urgent need to be provided with well-documented informations about "teaching of(expecially, via) problem solving" though following research issues ：ⅰ) the role of the teacher in a problem-centered classroom, ⅱ) what actually takes place in problem-centered classrooms, and iii) groups and whole classes' problem solving rather than individuals. This paper intends to give some informations about practice of teaching mathematical problem solving in elementary school.ry school.

이 연구는 2년차 신임 교사의 사례 연구를 통해 수학수업에 대한 신임교사의 발문 유형의 특성을 분석하고 그에 따른 대안을 탐색하기 위한 것이다. 연구 결과, 확인을 위한 발문이 가장 많았으며(69%), 이해를 위한 발문(25%), 성찰을 위한 발문(6%) 순이었고, 창의성 신장을 위한 발문은 하지 않는 것을 알 수 있었다. 더불어 기존 연구를 바탕으로 신임교사의 발문과 관련된 대안적인 창의성 신장을 위한 발문을 제안해 보았다.

본 연구에서는 예비교사와 경력교사가 수학 수업지도안을 읽고 이해하는 과정을 시선 추적(Eye-tracking)을 통해 분석하였다. 두 그룹의 시선 데이터를 분석한 결과, 예비 교사들은 수학 수업지도안을 경력교사에 비해 어렵게 느끼고 있었으며 선조적인 방식으로 수학 수업지도안을 읽고 이해하였다. 반면, 경력교사들은 수학 수업지도안의 흐름을 파악하기 위해 핵심 주제어들을 찾아 연결성을 만들어가는 하이퍼텍스트 읽기 전략을 활용하였으며 수학 수업모형의 핵심 영역을 방문하는 시간이 유의미하게 길었다. 이러한 결과를 바탕으로 예비교사들이 수학 수업지도안을 읽고 이해하는 역량을 지도할 때 숙고해야할 여러 시사점들을 도출하였다.

본 연구의 목적은 초등교사의 수학수업의 질, 수학 교수효능감, 학생의 수학흥미와 수학성취도 사이의 구조적 관계를 살펴보는 것이다. 이를 위해 TIMSS 2015 한국자료를 다층구조방정식을 적용해 분석하였다. 분석 결과, 학생수준에서 학생이 평가한 수학수업의 질은 학생의 수학 흥미에 정적인 영향을 미치며 수학흥미는 수학성취도에 정적인 영향을 미치는 것으로 나타났다. 또한 수학수업의 질이 수학성취도에 미치는 직접효과는 통계적으로 유의미하지 않았으나 수학흥미의 매개를 통한 총효과는 유의미한 것으로 나타났다. 학교수준에서 평균적 수학수업의 질, 수학 교수효능감은 학생의 수학흥미에 정적인 영향을 미치는 것으로 드러났다. 그러나 수학수업의 질, 수학 교수효능감, 학생의 수학흥미가 학교의 평균적 수학성취도에 미치는 직접효과는 통계적으로 유의미하지 않았으며, 수학수업의 질과 수학 교수효능감이 수학흥미의 매개 효과를 통해 학생의 수학성취도에 미치는 총효과는 유의미한 것으로 나타났다. 이상의 결과를 바탕으로 교육적 시사점을 제시하였다.

Education emphasizes problem-solving skills based on convergent thinking power in an era of rising uncertainty and rapid progress. This paper proactively designed e-Learning team teaching convergence liberal arts courses for prospective teachers by these social needs. It analyzed the empirical effects on the operation of the subjects to foster future talent who can converge and apply knowledge in various fields. The curriculum consisted of professors of mathematics, practical Arts, computer, and education, and was operated to convey convergent knowledge of information technology and humanities, and consisted of 15 liberal arts courses at J University. Besides, textbooks and teaching materials were also developed by the faculty. As a result of the primary research, prospective teachers who took the course generally showed high satisfaction with the class, especially for the faculty. The students' overall convergent thinking ability has increased to a statistically significant level (p<.01), and the students' major has been found to be irrelevant. On the other hand, it can be seen that communication, content convergence, and caring factors, excluding creativity factor, have all risen to a significant level.

Open-ended problems can foster deeper understanding of mathematical ideas, generating creative thinking and communication in students. High-order thinking tasks such as open-ended problems involve more ambiguity and higher level of personal risks for students than they are normally exposed to in routine problems. To explore the classroom-based factors that could support or inhibit such higher-order processes, this paper also describes two cases of Singapore primary school teachers who have successfully or unsuccessfully implemented an open-ended problem in their mathematics lessons.
