This study aims to figure out the characteristics of the mathematical ability of multicultural Korean elementary school learners. This was done by analyzing the results of a mathematics diagnostic test given to multicultural Korean first and second year elementary school students. The findings of this study mainly support the following three. First, it was indicated that, regardless of whether the students are multicultural or not, more second-year students had difficulty in understanding mathematics than the first-year students. Specifically, a higher percentage of second-year students were below the reference point (cut-off point) than was the case in the first-year learners, which pattern of the overall Korean students was consistent with that of multicultural Koreans. Second, concerning the sub-fields of mathematics, higher proportion of the students fell below the cut-off point in 'numbers and arithmetics' area than in 'measure and geometry,' which pattern was again the same with the multicultural students. Third, it was implied that, in addition to mathematically more complex questions, linguistically complex sentential representations contributed to increasing the difficulty of the test items. It is suggested that care be taken to enhance linguistic processing and to employ well-defined terms.

The purpose of this study is to develop a 'Competency Model for Beginning Teachers in Home Economics'. The study was conducted in a total of 4 stages(preparation of competency model development stage, materialization stage, validity verification stage, and competency diagnosis stage), and the results of the study were as follows. First, the first tentative competency model was derived through the literature study, and the secondary tentative competency model was derived through an FGI. The validity of the secondary tentative competency model was verified by 15 experts and the competency groups, competencies, and competency definitions from this study were found to have content validity. Second, the competency diagnosis was conducted for a total of 222 beginning teachers in Home Economics. As a result, a total of 7 competencies were derived as the 'top priority competencies' that are of first priority for beginner teachers in Home Economics. The final competency model which was developed by reflecting the research results, was composed of 4 competency groups and 22 competencies and 22 competency definitions. The competencies of each competency group were presented in the order that beginning teachers thought were important. This study is meaningful in that it used an FGI and competency diagnosis to identify beginning teachers' perceptions and demands of the competencies and reflect the results on the competency model development.

In this paper, we analyzed the freshmen's achievements on general mathematics their GPA based on 'basic mathematics diagonal test score'. Also, we studied the achievements of students who were not passed the 'Basic Mathematics Diagonal Test (BMDT)' and had to take supplementary lessons to improve their mathematics abilities four times a week during the first semester of academic year 2008 in Mokpo National University. Before taking college entrance exam, high school students had to choose two types of scholastic area. One is on 'Ga' or 'Na' in mathematics and the other is on Natural Science or Social Science. According to the types, we classified the freshman-Ga or Na and NS or SS. We found some facts. First, a few of Ga and NS freshmen had low score on the BMDT. Second, Na and NS freshman got higher score than Na and SS freshmen on the BMDT. Third, Ga and NS freshmen who passed the BMDT got higher score on the general mathematics than those who failed the BMDT. Finally, there are correlations between achievements of general mathematics and a curriculum of freshmen who were passed test after taking supplementary lessons.
