This study sampled 6,535 grade 11 or 12 students in South Korea using a stratified random sampling method in order to identify the differences in the perception of students on what a good mathematics class is by school class and region. The results showed that four elements of a good mathematics class were significantly different among school classes and regions.

The purpose of this study was to research and compare teachers' preferences for 'Great Math Class' by region and gender. The research was conducted on 261 high school math teachers by using non-probability sampling. As the results of the study, regional preference had no statistically significant difference in all four factors of 'Great Math Class' while gender preference had statistically significant difference only in the factor of teaching (methods) and learning methods. Both region and gender had statistically significant positive (+) relationship with preference for all four factors. This implies that it is necessary to consider socio-cultural factors rather than teachers' perception on class for regional differences in academic achievements in mathematics.

Recently a new type of educational method through the internet, distance education, has been developed with technology development. To find out any complement between distance education and traditional in-class education, a series of study with junior high school mathematics were conducted. Both distance education and in-class education have merits and shortcomings. Some advantages with distance education shown from the study can be used for complement to in-class education depending on the contents and subjects. Distance education in mathematics education can be a good turning point for future education.

본 연구는 수학학습부진아의 노트쓰기 활동에 관한 사례연구로서 개별적인 노트쓰기 지도의 효과가 수학 학습부진아의 학습태도에 미치는 영향에 대한 사례를 탐구해 보는 것이다. 충남에 소재한 고등학교의 3학년 학생을 대상 중 학습부진아를 선택하여 연구하였고, 특별한 학생에게 맞춤으로 새롭게 구성한 수학노트를 활용하여 수업을 진행하였다. 매 수업시간이나 그 이후의 시간을 이용하여 스스로 노트를 정리하게 하였고, 일정기간마다 노트를 제출하여 교사의 피드백을 받을 수 있게 하였다. 본 연구의 결론으로서 학생의 개별화 지도를 위하여 개인적으로 수학노트 쓰기를 활용한 수업은 수학학습부진아들의 학습 태도와 흥미 변화에 긍정적인 영향을 미치고 있는 것으로 나타났다.

이 연구는 좋은 수학 수업에 대한 고등학생의 인식을 분석하고 선행연구와 비교를 통하여 수학 수업에서 교사와 학생들 간의 인식 차이로 발생하는 수업의 갈등 해소를 위한 시사점을 제시하고자 했다. 이를 위하여 설문조사 결과를 중심으로 학생들을 학년 과정별, 등급별, 성차별로 분류하여 그들 사이의 인식을 분석하고 비교하였다. 학생들은 집단 분류에 관계없이 그들이 갖고 있는 오개념을 파악하여 수정해주는 수업에 대한 선호도가 가장 높았다. 인문사회과정 학생, 중위권 학생, 여학생들은 그들의 수준을 고려한 수업과 평가 및 수업 중 다룬 내용을 평가하는 수업에 대한 선호도가 높으며, 하위권 학생들은 그들의 사고과정을 이해하고 의사소통이 잘 이루어지는 수업에 대한 선호도가 다른 등급 학생들보다 높았다. 이로부터 인문사회과정 학생, 등급이 하위권인 학생들은 수학에 대한 자신감, 흥미, 가치인식이 향상되고 수학 수업이 긍정적인 경험이 될 수 있는 수업분위기에서 지도가 필요함을 시사하고 있다.

This paper shows how the social tradition and belief of korea on education affects teachers and students and learning. 1 Interview with teacher. During surveying this teacher's class, we knowed that the teacher have accentuated algorism loaming and preparation fur external examination in math class. Teacher's beliefs about mathematics have a strong effect on the method of class and the performance of problem solving 2. Interview with students and short test. 1) Students usually had fine ability of calculation for number. But Many pupils didn't know the meaning of the operations. 2) The most of pupils are good at routine math problem solving but when the question whose the condition don't meet was given, they experienced difficulties.3.Korean sociocultural specialty on education: The korean place high emphasis on education and think of education as the means of success. This emphasis can be traced to the Confucian view. 1) tradition on examination culture. 2) the traditional convention of the learning method. Korean sociocultural specialty on education play role of strengthen role learning and algorism class. The important things to education reformation are getting a balance between practice and understanding. we should make changes not only in national dimension but also in math class.

A good amount of work has been done on degree of approximation of functions belonging to Lip${\alpha}$, Lip($\xi$(t),r) and W($L_r,\xi(t)$) and classes using Ces$\`{a}$ro, N$\"{o}$rlund and generalised N$\"{o}$rlund single summability methods by a number of researchers ([1], [10], [8], [6], [7], [2], [3], [4], [9]). But till now, nothing seems to have been done so far to obtain the degree of approximation of functions using (N,$p_n$)(C, 1) product summability method. Therefore the purpose of present paper is to establish two quite new theorems on degree of approximation of function $f\;\in\;Lip({\alpha},r)$ class and $f\;\in\;W(L_r,\;\xi(t))$ class by (N, $p_n$)(C, 1) product summability means of its Fourier series.

As students have been familiar to Internet or media which has big visual effects rather than letters, they preferred the class in computer lab to theoretical class. The class in computer lab showed all the students good reactions in concern and interest. Statistics achievements of high level students in 2008 became better than that in 2007 but those of low level students became worse than that in 2007. I analyze the reason why the achievements of low level students have become worse. The purpose of this study is to supplement of the trouble of the class in computer lab and find out a better teaching and develop mathematics education's satisfaction and qualification.

This study analyzed the quality of mathematics classes with observations using the instrument, MQI(Mathematical Quality of Instruction). Class recordings and interviews were conducted on 2 pre-service teachers and 4 in-service teachers. This study recorded and analyzed 3 or 4 classes for each mathematics teacher by using revised MQI. There were a total of 8 raters: 2 or 3 raters analyzed each class. MQI has four dimensions: Richness of the Mathematics, Working with Students and Mathematic, Errors and Imprecision, Student Participation in Meaning-Making and Reasoning. In the dimension of 'Richness of Mathematics', all teachers had good scores of 'explanations of teacher' but had lower scores of 'linking and connections', 'multiple procedures or solution methods' and 'developing mathematical generalizations.' In the dimension of 'Working with Students and Mathematics', two in-service teachers who have worked and having more experience had higher scores than others. In the dimension of 'Errors and Imprecision', all teachers had high scores. In the dimension of 'Student Participation in Meaning-Making and Reasoning', two pre-service teachers had contrast and also two in-service teachers who hadn't worked not long had contrast. Implications were deducted from finding to improving quality of mathematics classes.

This study is on the use of mathematics program for School Mathematics Education. According to the ‘technology principle’ by NCTM and teaching-learning methods by the 7th curriculum, we developed mathematics learning activities with mathematics program. This activity is to construct designs with graphs by using mathematics program(GrafEq.). In this study, we practiced these learning activities with pre-service mathematics teachers. The mathematics educational effects of these learning activities in this study are analyzed as follows; active & spontaneous search for mathematical knowledge, the experience of problem solving, affirmative view-point of mathematics, understanding of practical use of mathematics, acquisition an interest & motivation of learning mathematics etc. When students learn graphs of function, the concept of inequality in secondary school mathematics class., mathematics teachers can make a good use of constructing designs by mathematics program(GrafEq.). This will help to practice of teaching-learning methods by the 7th curriculum.
