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.

This study explored teachers (n = 219) from northern, central, southern and eastern Taiwan concerning their views about children's learning difficulties, mathematical instruction and school mathematics curricular. Results showed that teachers' mathematics knowledge or their instruction methods had no significant influence on their views of children's learning difficulties. Even though teachers indicated that understanding of abstract mathematical concepts was the most prominent difficulty for children, they tended to employ direct instruction rather than constructive and cooperative problem solving in their teaching. However, teachers' views of children's learning difficulties did influence their instructional practice. Results from in-dept interviews revealed that there were some obstacles that prevented teachers from putting constructiveism perspectives of instruction into teaching practice. Further investigation is needed to develop a better understanding of epistemology and teaming psychology as well as to help teachers create constructive learning situations.

This paper analyzes the difficulties with the learning of sequence and series of the second-year students who participated in a year long whole class at the university level. The research was carried out at the end of students' third semester. These students were randomly selected. They were applied to one paper and pencil test containing eight task items on sequence and series. In this study, qualitative method (case study design) was used to explore students' difficulties and misunderstandings in learning sequence and series. Students' responses to the questions were divided into three categories: These were "correct", "partial correct" and "false or no responses". Students' responses to the paper and pencil test were evaluated. The results show that students had difficulties and misunderstandings in series and sequence.

본 연구에서는 중학교 3학년 수학학습부진아가 함수 분야에서 나타나는 어려움과 이에 대한 지도방안에 대해 알아보고자 하는 목적으로 좀 더 심층적인 학습 부진 요인을 알아보기 위해 설문지, 인터뷰, 녹음과 관찰 등을 통한 사례연구를 하였다. 그 결과 수학학습부진아는 일반 학생들이 겪고 있는 어려움과 유사한 어려움을 겪고 있었다. 다음으로 수학학습부진아는 일반 학생들이 겪고 있는 어려움과 차이를 보이는 어려움으로 문제를 이해하는 데 어려움, 선수 학습 결손으로 인한 어려움, 형식화하여 답을 찾으려고 하는 어려움, 대수 기호의 구분을 정확히 하지 못함으로써 겪는 어려움 그리고 두 점을 지나는 직선의 기울기를 구하는데 있어 어려움을 겪는 것으로 나타났다.

Mathematics textbook plays a significant role in shaping students' learning of mathematics. Logic, rigor and abstraction as typical features of the formalization of mathematics, dominate mathematics textbooks around the world, which is regarded as one of the important origins of students' learning difficulties in mathematics. An innovative series of Chinese mathematic textbooks is presented in this paper. Supported by the supplementary materials excerpts from the textbooks, it gives a comprehensive theoretical analysis of the principles of design and implementation of this series of mathematics textbooks. The effectiveness of this series of textbooks is demonstrated by student achievement and secondary research data. It shows that series of Chinese mathematic textbooks has largely decreased students' learning difficulties in mathematics and enhance classroom teaching efficiency. It suggests that prioritizing the essence of mathematics and reducing abstraction is an important notion for mathematics textbook design and implementation.

본 연구는 예비 수학교사들이 이산수학 학습에서 겪는 어려움의 원인과 배경을 조사·분석하여 교사 교육 개선에 도움을 주고자 함이다. 이를 위해 예비교사를 대상으로 이산수학 교과목에 대한 설문과 지필평가를 실시하고 여기서 얻은 자료를 분석하였다. 그 결과 첫째, 이산수학 교육의 필요성에 대한 예비교사들의 가치 인식 공유가 요구된다. 둘째, 이산수학 내용요소의 적정성 및 이수 시수의 검토가 필요하다. 셋째, 예비 수학교사들이 갖는 학습 곤란의 발생 원인을 학습요인 이외의 측면에서 살펴볼 필요가 있다. 그리고 중등 학교수학과 대학의 이산수학 교육과정 연속성 측면에서 내용요소의 체계성, 계열성 연구가 필요하다는 것과 중등임용에서의 이산수학 출제 비율 조정에 대한 신중한 고려가 요구된다는 시사점을 도출하였다.

시대적 흐름과 정부의 정책 시행 노력에도 불구하고 수학학습에 어려움을 호소하는 학생들이 많이 늘어나고 있다. 이를 반영하여 수학교육에서 수학학습부진아와 관련된 연구가 많이 시행되었다. 하지만 이러한 연구들의 대부분은 수학학습부진아의 원인을 밝혀내거나 교수학적 처치를 시행하고 그 효과를 알아보는 실험연구가 대부분이었다. 따라서 본 연구에서는 학위논문 및 학술지 논문 49편을 메타분석하여 수학학습부진에 대한 교수학적 처치가 학업성취도 향상에 얼마나 큰 효과크기를 갖는지 분석하였다. 이러한 분석의 결과 수학학습부진아에게 교수학적 처치는 전반적으로 중간 정도의 효과크기를 갖는다는 것을 알게 되었다. 또한 여러 중재요인을 분석하여 어떠한 환경에서 가장 큰 효과를 거둘 수 있는지에 대한 제안점도 얻을 수 있었다.

The purpose of this study is to investigate the recognition fur mathematics subject in the 5th and 6th graders elementary students. To carry out this study, the 5th and 6th graders recognition as learning mathematics subject was investigated by questionaire. The questionaire was analysed by using frequency and percentage. The 5th and 6th graders had difficulties in the hierarchical problem because mathematics is very systematic and hierarchical, and other had difficulties in studying mathematics because the explanation of the problem solving process in the textbook was not detailed. Others had difficulties in studying mathematics because of quick loaming progress, in applying the formulas and property of mathematics.

본 연구에서는 중학교 2학년 도형의 성질 단원의 증명학습을 세 단계로 나누어 설문을 통하여 학생들이 증명학습에서 겪는 어려움을 조사하였다. 설문 분석 결과 학생들은 증명학습에서 증명의 의미를 이해하지 못해 명제의 참을 판단하는 정도의 간단한 추론도 하지 못할 뿐만 아니라 제시된 증명을 읽고 그것이 증명하려는 명제의 가정과 결론을 파악하지 못한다. 이는 학생들이 명제의 가정과 결론의 의미와 역할을 명확히 이해하지 못하는데서 비롯된다. 따라서 학생들에게 명제의 가정과 결론의 의미와 역할에 대한 지도에 좀 더 역점을 두는것이 필요하다.

Problem solving is an important aspect of learning mathematics and has been extensively researched into by mathematics educators. In this paper we analyze the difficulties students encounter in various steps involved in solving problems involving physical and geometrical applications of mathematical concepts. Our research shows that, generally students, in spite of possessing adequate theoretical knowledge, have difficulties in identifying the hidden data present in the problems which are crucial links to their successful resolutions. Our research also shows that students have difficulties in solving problems involving constructions and use of symmetry.
