이 논문은 수학 교사의 신념과 지식이 수학 수업에 어떻게 표현되는 지 미국 중학교 수학 교사의 수업 분석을 통한 사례연구 보고서이다. 미국 중학교 수학 교실에서 이루어지는 수업에 대한 정보를 제공할 뿐만 아니라, 수학교사의 신념과 지식이 수업에 어떻게 반영되고 적용되는지 상세하게 분석 설명한다. 사례 분석 연구 결과는 참여 수학 교사의 수학 교수학습에 대한 신념체계가 수업에 일정 정도 일관성 있게 표현됨을 보여 준다. 특히, 그 교사의 신념체계가 수학 수업을 조직하고 구성하는데 큰 영향을 미치는 것으로 나타났다.

이 연구의 목적은 중학교 교수내용지식이 수업을 통하여 어떻게 나타나는지 다양한 형태의 교사 지식을 분류하고 분석하는 것이다. 연구 결과, 연구에 참여한 두 명의 수학 교사의 지식은 유사하면서도 다른 구조의 형태를 띠고 있었다. 한 교사는 수학 내용 지식과 학생에 대한 지식을 더 많이 사용하는 것으로, 다른 교사는 교수적인 전략과 수학내용 지식을 더 많이 활용하는 것으로 나타났다.

In the 2015 revised mathematics curriculum, the system of equations is first introduced in 'Variables and Expressions' of [Middle School Grades 1-3]. Then, It is constructed that after learning the linear function in 'Functions', the relationship between the graphs of two linear functions and the systems of linear equations are learned so that students could improve the geometric representation of the systems of equations. However, in of Elective-Centered Curriculum Common Courses, Instruction is limited to algebraic manipulation when teaching and learning systems of quadratic equations. This paper presented the teaching and learning method that can improve students' mathematical connection through various representations by providing geometric representations in parallel using GeoGebra, a mathematics learning software, with algebraic solutions in the teaching and learning situation of simultaneous quadratic equations.

Over the last three decades, there has been an increasingly strong emphasis on group-centered approaches to mathematics teaching. One primary responsibility for teachers who use group-centered instruction is to "check in", or intervene, with groups to monitor group learning and provide mathematical support when necessary. While prior research has contributed valuable insight for successful teacher interventions in mathematics group work, there is a need for more fine-grained analyses of interactions between teachers and students. In this study, we co-conducted research with an exemplary middle grade teacher (Ms. Green) to learn about fine-grained details of her intervention practices, hoping to generate knowledge about successful teacher interventions that can be expanded, replicated, and/or contradicted in other contexts. Analyzing Ms. Green's practices as an exemplary case, we found that she used exceptionally short interventions (35 seconds on average), provided space for student dialogue, and applied four distinct strategies to support groups to make mathematical progress: (1) observing/listening before speaking; (2) using a combination of social and analytic scaffolds; (3) redirecting students to task instructions; (4) abruptly walking away. These findings imply that successful interventions may be characterized by brevity, shared dialogue between the teacher and students, and distinct (and sometimes unnatural) teaching moves.

This thesis is to see if the classes using problem posing is effective to improve the students' grades in math. So I set up research subjects as follow. 1. Do the classes focused on problem posing have any influence on the students' achievement\ulcorner 2. Do the classes focused on problem posing have any different influence on the students' achievement according to their levels\ulcorner 3. Do the classes focused on problem posing have any different influence on the students' achievement according to the categories in math\ulcorner I close four classes in the first grade of K middle school in Kangnung, Kangwon province for this thesis. First I divided them into two groups. Each group consisted of two classes. One is the experimental group. The other is the comparative group. The experimental group was taken classes using problem posing. The comparative group was taken classes by the traditional teaching method. And then I analyzed the difference of the achievement between two groups. As a result of this research, I came to the conclusion as follow. First, the classes focused on problem posing is more effective than traditional teaching method for the improvement of the students` achievement Second, both the classes using problem posing and the traditional teaching method doesn`t affect to the advanced students. Third, the classes using problem posing is more effective to the intermediate students and lower level students than the traditional teaching method. Especially it is very effective in teaching the students the linear equation.

The purpose of this study is to consider students′ scholastic relationship in mathematics between elementary school and middle school from the 3rd grade in elementary school to the 2nd and the 3rd grades in middle school. The following are the results: 1. CONCLUSIONS 1. Students′ present scores are most closely related to those of their previous grade. The data are based on the two groups of the 3rd grade middle school students - one is honhappan(mixed students from different elementary school) and the other shinaepan(the students from the same elementary school in kong ju city). This close relation between present and previous scores in mathematics may well be reasonable since mathematics is systemized hierarchically. Among the score data in elementary school, the scores in the 5th grade are meaningfully related to present score data in mathematics. 2. Two pans (as I mentioned above, honhap and shinae) are divided into groups and their scores are traced from the 3rd grade in elementary school and the data show that the high-levelled students have little changes in their scores, but low-levelled students have dropped radically in their scores from the first grade in middle school. 3. In terms of students′ interests, students who answered, "I′m very interested in mathematics." have no distinguished characteristics in their scores while those who answered, "I have little interest in mathematics" shows a decrease in their scores. 4. Among the reasons for their lack of interests, the replies are "because of exams," "because of teaching methods," and "because of the textbooks." II. Suggestion To compensate the limitation and difficiency of this study, the foll owing is suggested for the following studies related to this one. 1. This study was limited to gathering students′ score data from female students in a small city. For a more accurate statistic a bigger population is needed as well as varied geographical and social economical area is suggested. A good idea is to study homogeneous sex groups as well as heterogeneous sex groups 2. It is easy to find out what grade is closely related to the present scores by statistical analysis, but the reasons for their relationship have to be found out through the following studies 3. There are many studies on cognitive domain in math but it is expected to have more studies on affective domain as well.

본 연구는 스토리텔링 수학 수업을 통하여 중학교 3학년 수학학습부진학생들의 수학적 태도를 긍정적으로 변화시켜 수학에 대한 흥미를 가지게 하는데 그 목적이 있다. 이를 위하여 수학 성적이 하위 20% 이하인 학생 5명을 선정하여 함수 단원의 스토리텔링 학습자료를 구성하여 18주동안 36시간의 수업을 진행한 후, 수학적 태도에 관한 사전 사후 설문과 인터뷰를 실시하였다. 연구 결과, 사전 사후 설문의 평균이 증가하였고, SPSS 대응표본 t-검정도 통계적으로 유의미한 결과를 얻었다. 특히 수학적 태도의 여러 세부 항목들을 각각 분석한 결과 '학습 기술 적용'에서 가장 큰 변화를 보였으며, 다음으로는 '흥미도', '자율 학습' 순으로 긍정적인 변화를 확인할 수 있었다. 그러므로 스토리텔링 수업이 중학교 3학년 수학학습부진학생의 수학적 태도에 긍정적인 효과를 미침을 확인할 수 있었다.

During the recent years at a middle level Engineering School located at the local areas in Korea, more than 20 percent of freshmen had failed at their first College Mathematics. In consequence, many of them had hard time to survive at their major curriculums. The purpose of this study is to look for the main reasons of their failure and suggest an alternation of the present curriculum. Using the responses to the questionnaires and placement test scores, we studied the characteristics of the students' Mathematical abilities and analyzed how they were related to their grades of the First College Mathematics at the end of the first semester. The mathematical ability of the students at the middle level Engineering School turned out to range from bottom to top even though most of them revealed their interests towards Mathematics. The students with low scores at the placement test were more likely to fail at their first College Mathematics. Thus we suggest that the school should open a new preparation course ahead of the First College Mathematics for those who achieve low scores at the placement test and also professors should write proper books and develop ways of teaching.

본 연구에서는 중학교 3학년 학생들에게 닮은 삼각형의 대응변 사이에 성립하는 비례적 성질에 기초하여 역동적 기하환경에서 이차방정식 $x^2-ax+b^2=0$의 해를 작도할 수 있는 기회를 제공하였다. 이 예비연구를 통해 이차방정식의 해에 대한 학생들의 기하학적 직관을 촉진시키고 $a$와 $b$의 값에 따라 이차방정식의 해가 어떻게 달라지는지 시각적으로 확인해 보게 하였다. 또한, 이 과정에서 학생들이 이차방정식의 해를 구하기 위해서 어떤 전략을 사용하는지 분석하여 이차방정식 지도 방법의 새로운 가능성을 살펴보고자 하였다.
