본 연구는 수학적 과정을 고려한 측정 활동의 구성을 통해 측정 영역에서 추구하는 목표에 도달할 수 있다는 가정 아래 초등학교 4학년 학급에 측정 오차를 활용한 삼각형의 내각의 합 지도 방안을 적용하고 결과를 분석하였다. 연구 결과 첫째, 학생들은 측정 오차를 활용하여 삼각형의 내각의 합을 학습함으로써 측정 오차의 발생 가능성을 인식할 수 있었다. 둘째, 측정 오차에 기반한 토론 과정은 학생들이 수학적 정당화를 시도할 수 있는 바탕이 되었다. 셋째, 반원을 활용한 조작 활동은 학생들에게 자연스럽고 직관적인 수학적 정당화의 방법으로 인식되었고 일반화를 이끌었다. 넷째, 측정 오차를 활용한 삼각형의 내각의 합 지도 방안은 학생들의 수학적 의사소통 능력과 수학에 대한 긍정적인 태도의 함양에 기여하였다.

In this paper, we introduced that the differences and reasons about oriental and western consciousness structure by borrowing from Dr. Richard E. Nisbett who is a professor of Michigan University of USA and writer of . And then, we introduced two survey results about likeness, dislikeness and aesthetic sence on mathematics. In their surveys, we researched the differences and attitudes between Korean male students and female students. Furthermore, we present a new educational curriculum to promote university students' various culture consciousness on mathematics.

There arc numerous techniques available to appraise pupil achievement in elementary school mathematics. The teacher must utilize a variety of approaches to assess pupil growth in the mathematics curriculum. Each evaluation technique has its strengths as well as weaknesses. Thus, a specific evaluation technique may be utilized as a check on other approaches to appraisal. Pupil achievement must be assessed in terms of stated relevant understandings. skills, and attitudinal objectives. It is not adequate to appraise pupil growth in terms of understandings objectives only. Pupils must also be assessed in terms of skills objectives. The understandings acquired by learners must be utilized; thus, skills objectives need to be stressed adequately in ongoing units of study in elementary school mathematics. Adequate emphasis also needs to be placed upon pupils achieving attitudinal goals. Desireable attitudes on the part of learners aid in achieving understandings and skills objectives. A defensible program of evaluation would then stress that pupil achievement be adequately appraised in terms of understandings, skills, and attitudinal objectives.

This study basically investigates the meaning and properties of performance task applicable to mathematics classroom and it finds out how to run effectively performance task activities included in the present mathematics textbooks. To accomplish this, this study deals with twelves kinds of mathematics textbooks for ninth graders and is proceeded on the basis of textbook analysis and teacher interview. Considering a situation that in future mathematics textbook would be developed, according to the analytic results of this study, common understanding of performance task and qualified performance task are needed, a variety of tasks classified by differentiated level are needed. In addition, each task should be dealt with the contents related to curious and interesting real-life situations. Furthermore, fairness of checking and recording should be established and teachers' positive attitudes to applying performance tasks to math class are needed.

Utilizing the quantitative analysis methodology of questionnaire, the study explores the differences in the factors of achievement motivation, learning mathematics attitude and learning mathematics self-confidence and also the relationship between mathematics academic achievement and these factors in three areas in China. The following conclusions are drawn: 1. The subjects from different development level areas have significant differences in motivation, attitude and self-confidence in mathematics; 2. The subjects from different areas who possess the same ethnic group have significant differences. But the subjects from same area who possess different nationalities have little difference. It can be concluded that that the differences in these factors can be contributed to regional differences, rather than to ethnic differences; 3. The subjects from undeveloped areas have significant gender differences, and the levels of males are higher than those of female.

The History of Mathematics (HOM) was integrated in teaching the Cartesian Coordinate Plane (CCP) to Grade Seven learners of Moonwalk National High School using Lesson Study. After the lesson was taught, there were three valuable issues emerged: (1) HOM is a Springboard and/or a Medium of Motivation in Teaching CCP; (2) The History of CCP Opened a Wider Perspective about Its Real-life Application in the Modern World (3) Integration of History Developed a Sense of Purpose and an Appreciation of Mathematics Among Learners. Feedbacks solicited from the learners showed that they have understanding of the importance of studying Mathematics after they learned the life and contributions of Rene Descartes to Mathematics. Hence, integration of history plays a vital role in developing positive attitudes among learners towards Math.

Through quantitative video analysis of four algebra classes and statistical analysis of various types of teacher evaluation behavior in the classroom teaching, we get: (1) Teacher evaluation behavior in classroom is close to take 1/5 of the total time of the classroom teaching, and it appears most frequently in class exercises and take the longest time; (2) There are many forms of teacher evaluation behavior in classroom, and most of the behaviors are positive assessment; (3) Recognition evaluation is relatively conservative in a single form without losing fairness; (4) Classroom assessments of teachers' behaviors are primarily concerned about students' knowledge and skills mastery, and it is less involved in student feelings, attitudes and behaviors; (5) The correct teacher evaluation behavior in classroom will inspire students to create internal motivations; and (6) The correct teacher evaluation behavior in classroom can stimulate the potential of students.

This research is a laboratory study for the improvement of differential equation class, and the aim of this study is to propose the possibilities of applicable writing activities for differential equation courses in university. We analyzed how the writing activities can affect the improvement of abilities of the students' affective domain and cognitive domain. Although the results from the two areas did not show a big numerical improvements it proved that the writing activities have positive effects, especially for the group of lower level students. The students felt interested and became more confident with differential equation studies. Their understanding of the study has been increased further by acquiring new learning methods, including writing activities. Therefore, we conclude that teaching and learning method designed systematically to adopt writing activities improve the students' learning attitudes and achievements.

The purpose of this study to analyze correlation for the tendency of mathematics anxiety, traits according to the factors of mathematics anxiety and mathematics attitude depending on the teacher variable through a survey of mathematics anxiety and attitude toward mathematics on teaching mathematics of elementary school teachers. To solve the questions above, sampled 250 elementary school teachers in Daegu province. As a result of the study, mathematics anxiety on teaching is not actually formed a lot. However, the more training experience with mathematics, previous academic career, education career were, the lower mathematics anxiety was. The results showed that mathematics anxiety is affected by previous academic career, training experience with mathematics in particular. In addition, we found that mathematics anxiety is affected by mathematics anxiety in their school, recognition of the ability to explain mathematics contents and attitudes toward mathematics.

This study sought to examine preservice teachers' beliefs about their intent to use computers and Internet resources in mathematics classrooms. Also, web-based instruction on topics in elementary school mathematics was used to foster teachers' confidence and competence in using instructional technology, thereby promoting positive attitudes toward use of computers and Internet resources in the mathematics classroom. The results indicated that students who participated in the web-based instructions exhibited a significantly (p < 0.05) better attitude toward using computers and web-based resources in teaching mathematics than did students in the control group.
