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.

This study is to figure out the activity of individual education with the note-taking in math class and correction and supportive explanations on attitudes toward learning of underachievers in mathematics in the second-year class of high school. This study has begun on the basis of the judgement that the note-taking especially correction and supportive explanations could help the underachievers in mathematics focus in class and develop good learning habits, and besides, students make a good relationship with teacher. According to this result, Many researches and exertions need to inform every student that mathematics is open and doing mathematics is a happy object. if the students who are underachievers were given the chance to organize their learning by themselves in the class with note-taking and correction and supportive explanations in the long-term, it should be effective enough to change their attitudes toward learning.

This study would suggest to analyze the perceptions of good mathematics teaching in high school and offer the resolutions for the conflicts caused by differences in perception between teachers and students in math class through previous studies and comparative implications. To this end, Students are classified by their courses, grades, gender awarenesses and they were analyzed and compared by the survey results. Although the preference for the math class that fixs the misconception of students is highest, regardless of the kinds of students groups. Academic students, middle-ranked students, female students have high affinity for the class to evaluate the material covered in class and take into account their level of assessment and instruction, low-ranked student's preference is higher for the class that has focused on understanding communicating their thinking processes than students. From this, it is suggested that academic students, low-ranked students are needed to be taught in a way that increases their confidence, interests, values and also in atmosphere that make math class a positive experience.

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.
