This study examined difficulties middle school students have in learning mathematics and proposed a flipped classroom consisting of Khan Academy activities, small-group problem solving, and mathematical modeling to help improve their learning. A mixed-method approach was used to identify difficulties students have in learning mathematics, explore how the flipped classroom helped them reduce the learning difficulties identified, and examine if there were differences in students' mathematics achievement and their affective characteristics after participating in the flipped classroom. Qualitative analyses showed that students had difficulties in understanding mathematical concepts and finding effective ways to learn as well as negative views towards learning mathematics. This study also found that each activity of the flipped classroom had a different impact on student learning. Before class, the Khan Academy activities were most likely to help students understand mathematical concepts. In class, small-group problem solving activities were most helpful for students who had trouble finding effective learning methods and environments. Mathematical modeling activities were most likely effective in changing students' negative views towards mathematics. A quantitative analysis showed that the flipped classroom not only significantly improved the students' mathematics achievement, but also positively affected their confidence and motivation and how much they valued learning mathematics.

Recently, for solving a math problem, and I reflect back, so much emphasis on activities which reflect the activities conducted in schools is necessary to look for. In this study, the 7th Mathematics Curriculum textbooks (10 - a, b) and 7th in mathematics and modification of curriculum textbooks (math) in the reflection type of activities that explore the resulting problems and the measures we discuss are. Therefore, textbooks reflect the type of activities were analyzed before and thinking strategies, and we will examine various types of reflective activities.

제7차 수학과 교육과정은 학습자의 능동적이고 구체적인 조작 활동을 통한 학습을 강조하고 이를 교과서에 ‘활동’이라는 형식을 도입함으로써 가시화하였다. 제7차 교육과정의 특징이라 할 수 있는 이 ‘활동’ 형식에 대하여 어떤 유형으로 분류될 수 있는지, 영역 또는 학년에 따라 어떠한 특징이 있는지, 활동 형식의 전반적인 특성에 대해 분석하였다.

본 연구에서는 사범대학 수학교육과의 '수학문제해결방법론' 강좌 시간을 이용하여 학교 수학의 효과적인 교수-학습을 위한 교육 활동을 실행하였다. 예비 수학 교사들을 대상으로 수학의 내용 이해와 지도에 도움을 줄 수 있는 시각적 자료를 탐구하도록 하고, 조별로 동료 학생들에게 그 내용을 지도하는 발표 수업을 진행하였다. 본 연구의 실행 과정을 통해 예비 수학 교사들은 자신의 수학 학습에 대한 인지적, 정의적 측면의 긍정적인 변화를 경험하였고, 수학 학습에 대한 인식의 변화, 자신의 수학 학습에 대한 반성, 교사로서 준비해야 할 점 등에 대해 깊이 생각해 보는 학습의 기회를 가지게 되었다. 본 연구에서 실행한 바와 같은 지도 사례는 학교 수학의 문제 해결 지도를 위한 예비 수학 교사들의 실천 지향적인 활동을 통해 그들의 교수 내용 지식의 성장을 도울 수 있다. 또한 직관이나 구체적인 조작 활동에 바탕을 둔 통찰 등의 수학적 경험을 제공해야 한다는 2007 개정 교육과정의 교수-학습 제안을 예비 수학 교사들이 실제 수업의 현장에서 구체화하는 데에도 도움을 줄 수 있다.

The present study examined the 7th national elementary school mathematics curriculum from a perspective of mathematical creativity. The study investigated to what extent the activities in the Pattern and Function lessons in the national elementary school mathematics textbooks promoted the development of mathematical creativity. The results indicated that the current elementary school mathematics curriculum was limited in many ways to promote the development of mathematical creativity. Regarding the activities in Pattern lessons, for example, most activities presented closed tasks involving finding and extending patterns. The lesson provided little opportunities to explore the relationships among various patterns, apply patterns to different situations, or create ones own patterns. In regard to the Function lessons, the majority of activities were about computing the rate. This showed that the function was taught from an operational perspective, not a relational perspective. It was unlikely that students would develop the basic understanding of function through the activities involving the computing the rate. Further, the lessons had students use exclusively the numbers in representing the function. Students were provided little opportunities to use various representation methods involving pictures or graphs, explore the strengths and limitations of various representation methods, or to choose more effective representation methods in particular contexts. In conclusion, the lesson activities in the current elementary school mathematics textbooks were unlikely to promote the development of mathematical creativity.

The present study explored whether the implementation of focused activities (intervention programme) can enhance 22 pre-service mathematics teachers' proficiency in solid geometry thinking level as well as change for the better their feelings in this discipline. Over a period of 6 weeks the pre-service teachers participated in activities and diversified experiences with 3D shapes, using illustration aids and actual experience of building 3D shapes in relation to the various spatial thinking levels. The research objectives were to investigate whether the intervention programme, comprising task-oriented activities of solid geometry, enhance mathematics pre-service teachers' mastery of their geometric thinking levels as well as examine their feelings towards this discipline before and after the intervention programme. The findings illustrate that learners' levels of geometric thinking can be promoted, entailing control on higher thinking levels as well as a more positive attitude towards this field.

Students experience many problem solving activities in school mathematics. These activities have focused on finding the solution whose existence was known, and then again conjecture about existence of solution or posing of problems has been neglected. It needs to put more emphasis on conjecture and problem posing activities in school mathematics. To do this, a model and examples of designing mathematical activities centered on conjecture and problem posing are needed. In this article, we introduce some examples of designing such activities (from the pythagorean theorem, the determination condition of triangle, and existing solved-problems in textbook) and examine suggestions for mathematics education. Our examples can be used as instructional materials for mathematically able students at middle school.

The purpose of this study was to examine contents and activities of patterns and functions in the 7th national curriculum for elementary school mathematics and textbooks developed based on it. Through examination, several conclusions were drawn as follow. First, pattern need to be introduced as a way of doing mathematics not as a subject of mathematics. Finding patterns is one of the most important mean to do mathematics. Second, activities for patterns and functions must be organized coherently. Coherent means that mathematical ideas are linked to and build on one another so that students' understanding and knowledge deepens and their ability to apply mathematics expands. Third, independent lessons for patterns and functions are needed. In these lessons, various activities need finding patterns can be introduced to help students understand mathematics. Fourth, the linkage between patterns and functions should be strengthened.

이 연구에서 초등학교 3학년을 대상으로 재구성할 Skemp 놀이활동이 학생들의 연산능력 신장과 정의적 영역에 어떠한 영향을 미치는지를 알아보았다. 덧셈ㆍ뺄셈 영역의 학업은 상대적으로 향상되었으나 실험집단과 비교집단의 평균간에 통계적으로 유의미한 차가 없었고 곱셈ㆍ나눗셈의 경우는 유의미한 차가 있었다. 우리는 Skemp 놀이활동 학습이 놀이수행에 필요한 암산 기회의 증가로 연산에 소요되는 시간이 짧아지고, 곱셈과 나눗셈의 연산능력도 상당히 향상된다는 것을 알 수 있었다. 또한 놀이활동에 끈기 있게 임하는 태도와 자신감이 크게 증가되었으며, 수학에 대한 태도가 긍정적으로 변화되었다.

본 연구는 학습자 스스로 수학적 오류를 분석하고 반성적 문제 만들기 활동을 하도록 한 것이 문제해결력과 수학적 태도에 미치는 영향을 알아보기 위한 것이다. 본 연구를 위하여 서울특별시 강서구에 소재한 초등학교 5학년 2개 반(62명)을 대상으로 실험집단과 비교집단을 선정하였다. 연구 결과 반성적 문제 만들기 활동은 학생들로 하여금 구하고자 하는 것을 파악하는 능력과 문제를 해결하는데 필요한 조건을 선별하여 활용하는 능력을 향상시켜 학생들의 문제해결력 향상에 효과적이었다. 또한, 학습자가 가지고 있었던 수학적 오개념을 수정하고 올바른 수학적 개념을 정립하는데 도움을 주었다. 그리고 반성적 문제 만들기 활동은 학생들의 수학적 의지를 향상시키고 반성적 사고를 촉진시키며, 반성의 과정에서 자연스럽게 스스로 자신의 문제를 풀이 과정을 점검하는 습관을 갖도록 하는데 도움을 주었다. 학습자는 반성적 문제가 올바르게 만들어졌는지 점검하고 이것을 바르게 해결하기 위해, 토의 활동에서 타인과의 수학적 의사소통에 적극적으로 참여하는 모습과 함께 끝까지 스스로 문제를 해결하고자 하는 과제집착력을 강하게 나타냈다.
