The purpose of the study were to analyze teaching models of arithmetic operations of integers in Korean middle school mathematics textbooks of the first grade and Americans', from which we compare and analyze standards for choice of models of middle school teachers and preservice mathematics teachers. We also analyze the effect of the choice of teaching models for students to understand and appreciate number systems as a coherent body of knowledge. On the basis of that, we would like to find the best model to help students understand and reason the process of formulate the arithmetic operations of natural numbers and integers into the operation of the real number system. Furthermore, we help these series of the study to be applied effectively in the middle school mathematics class in Korea.

The purpose of this paper was to discuss critical issues of 30% reduction and introduction of the contents for new Mathematics Curriculum at middle school in Japan in 2002. This paper consisted of three part: (1) The contents of the new mathematics curriculum in middle school in japan. (2) Discussion about critical issues of 30% reduction of the contents for new Mathematics Curriculum. (3) Proposal of the point of view about 2000 mathematics curriculum in Korea. The authors pointed out that the reduction of the mathematics curriculum in Korea should be considered of a true reduction more carefully.

This study aimed to investigate and compare perceptions of middle and high school mathematics teachers on assessment. For the purpose, we developed and used a survey consisting of two parts(importance/performance on assessment and general opinion on process-based assessment). We gathered data from 188 middle school and 125 high school mathematics teachers in Incheon area. An Importance-Performance Analysis(IPA) method was used for data analysis. As results, middle school mathematics teachers showed higher perception on both importance and performance in almost all area on assessment than high school teachers. In addition, research results based on teaching experience indicated that mathematics teachers having more teaching experience seemed to perceive high importance-high performance and low importance-low performance tasks more than mathematics teachers having less experience. In particular, middle school teachers recognized many low importance-high performance tasks according to their teaching experience. The IPA gave us different results depending on the school size. The larger the school, the more diverse opinions appeared tasks in low importance-high performance. From the general opinion on process-based assessment, the middle school mathematics teachers also seemed to have more positive perspectives and to be more active in assessment than high school mathematics teachers. Finally, we discuss implications for future policy formulation and implementation on process-based assessment.

This study is to explore the ways in which the affective characteristics of Korean middle school students have been developed and the ways in which they have an effect on their mathematics achievements by using TIMSS (the Trends in International Mathematics and Science Study) data of 1995, 1999, and 2003. In addition, this study investigates the differences in affective variables between boys and girls toward mathematics. The result of the study indicates that the affective characteristics of Korean middle school students have changed a little, but that its effect on mathematics achievement increased a lot from 1995 to 2003. This study also shows that the Korean students study mathematics to get a job than to enter a university. However, girls have come to study it harder before going to college and it seems to have an impact on their mathematics scores; this happened in 1999. So we can infer from it that the decreasing in the difference between boys and girls in mathematics achievement may have been influenced by the girls' learning motivation to go to college. Lastly, it should be said that another analysis is needed to find out the reason for the devaluation of the importance of mathematics among the Korean middle school students.

This study examines whether there is discrepancy between elementary and middle school mathematics teachers' beliefs and practices in constructed-response assessment and how their beliefs and practices are interrelated. Analyzing the responses of 212 elementary teachers and 189 middle school mathematics teachers to the questionnaire, we found that there is lack of consistency among elementary and middle school teachers' beliefs, practices, and expected benefits regarding constructed-response assessment. In addition, there was a weak correlation between each group of teachers' beliefs and expected benefits about constructed-response assessment. The results from this study imply that such inconsistency in elementary and middle school teachers' beliefs and practices regarding assessments may determine the effects of constructed-response assessment.

Investigating mathematics teachers in middle schools by questionnaire and interview, we find some problems of internal professional structure of mathematics teachers in middle schools. These are reflected in five aspects: professional theory, professional knowledge, professional ability, professional morality, reflection and innovative consciousness.

In order to educate future leaders of the new age, we should help students to increase their basic knowledge, thinking and problem solving ability. It is necessary that we should use multi-media, computer as well as old teaching-learning material to improve students' basic knowledge and to motivate their interest in mathematics in the small-sized Middle School situated on the agricultural and fishery village. In solving this problem, it is ultimately necessary that we should utilize CAI program on the learning achievement in mathematics for the students to understand basic concept, principle, law and to promote teaching-learning process considered on individual different abilities. Therefore, this study is on the effect of students' interest and learning achievement in mathematics when we develop CAI program focusing on the lesson statistics in the 3rd Grade Middle School Mathematics Textbook and explain the concept and principle of statistics through using exact and various techniques of computers

Mathematics is among the most important subjects in the middle school curriculum, yet the most hated subjects by students. The present study investigated the role of perceived executive functioning on the middle school student's mathematics achievement, after controlling for other psychological factors. Results showed that the students levels of executive functioning was predictive of their mathematics achievement test scores, even after motivational and attitude variables were controlled. The impact of the executive functioning was especially noticeable for the low achievers. On the other hand, for those whose scores were high, biological variables were the only significant predictors of their scores. The results of the present study imply that the intervention programs for improving mathematics achievement of middle school students should consider the different effect of cognitive and psychological factors on their achievements.

Since the center of mass of mathematics curriculum in middle school is dealt with only on triangle and it is defined as just an intersection point of median lines without any physical experiments, students sometimes have misconception of the centroid as well as it is difficult to promote divergent thinking that enables students to think the centroids of various figures. To overcome these problems and to instruct effectively the centroid unit in middle school mathematics classroom, this study suggests a teaching and learning method for the unit which uses physical experiments, drawing, and calculation methods sequentially based on the investigation of students' understanding on the centroid of triangle and the analysis of the mathematics textbooks.
