This paper shows that mathematics and statistics are not only a necessity but a strategic element in contributing for the competitiveness of field of S/W and H/W. First, a survey was conducted to investigate the perceived importance of mathematics and statistics to the specialists of the field. Second, computer programming was implemented in university mathematics courses to understand the educational effect related to problem solving ability. Third, a educational case in which mathematics and statistics in S/W and H/W subject were combined was analyzed. Lastly, an effective plan for mathematics and statistics education in the field of S/W and H/W will be presented.

In this study, we want to being helpful to improvement of ability to solve mathematical problem, that is grafted on the subjects being able to occur in real life, of students in teaching materials and results studied and developed in the university. For increasing ability to solve ingenious problem and growing in the learning ability of oneself leading of students. The goal of this study is to make possible open research as a result of that students look for problem around real life by one's own efforts and take interest in them through learning mathematics of parents of students, they are the most important fact of educational environment in the mathematics education - earlier than students. In particular, the goal of this study is that students have an positive attitude of mind for mathematics and maximize ability of practical application by the analytic thinking learned through experience of their parents, they survey, analyze and solve problems taken from real life in the method transmitting one's knowledge to others. This study is divided into 2 categories: education of students and education of their parents. By these, we want to disseminate advanced knowledge and theory through students improve the powers of thought, logic and inference, develop ability to solve mathematical problem, stir up motivation of learning and learn knowledge of mathematics become familiar with real life.

This research analyses spatial and temporal characteristics of the academic performances of high school students by using all 2,065,166 SAT scores for 3 years. The spatial inequalities in Seoul are analysed by DBMS and GIS. Based on three-year raw data of Korean SAT scores, the spatial and temporal characteristics of academic performances are scrutinized: 868,029 SAT scores cases of 2000 academic year on Novemver 17, 1999, 609,258 cases in 2005 academic year on November 17, 2004 and 587,890 cases in 2009 on November 13. The result shows that there are significant spatial disparities of the level of academic performance in Seoul by Gu level, also indicating that the disparities are getting wider over the course of time. The widening disparities by Gu level means that educational spatial inequality is intensified in spite of the increasing overall trend of academic performance of Seoul. It is also notable that disparities between regions are distinctive, while those in regions are not significant and sustained constant as time flows.

대학에서 학습효과를 높이기 위해 신입생들을 대상으로 기초학습능력검사를 실시하고 있다. 대학별 수시 비율이 높아짐에 따라 특성화고등학교 학생들이 입학의 기회 폭이 증가하였다. 이과와 문과의 계열성을 떠나 수학, 영어 등의 기본 교육과정이 다르기 때문에 대학에 진학해서 그동안 배우지 않은 전공 교과목에 많은 어려움을 느끼고 있다. 이에 본 연구는 보건계열 치위생과에 입학한 학생들의 가장 기본 전공과목인 치위생학개론 수업 전 구강에 관련된 지식을 다 각도에 따라 분석하여 이를 기초한 교수 학습 방법 및 학습자의 능동적인 수업 참여와 함께 동기 유발이 될 수 있도록 함에 있다.

The purpose of this study is to analyze of the effect in Mathematics Teachers beliefs on their students beliefs by Latent Class Regression Model (LCRM). For this analysis, the study used the findings and surveys of Kang, Hong (2020) who developed a belief profile by analyzing the mathematical beliefs of 60 high school teachers and 1,850 second-year high school students learning from them through the Latent Class Analysis (LCA). As a result It was observed that 'Nature of Mathematics', 'Mathematic Teaching' and 'Mathematical Ability' of mathematics teachers beliefs influence the mathematical beliefs of students. The teacher's belief of 'Nature of Mathematics' statistically significant effects on students' beliefs in 'School Mathematics', 'Problem Solving', 'Mathematics Learning'. The teacher's belief of 'Teaching Mathematics', 'Mathematical Ability' statistically significant effects on students' beliefs in 'School Mathematics', 'Problem Solving', 'Self-Concept'. The results of this study can give a preview of the phenomenon in which teacher's mathematical beliefs are reproduced into student's mathematical beliefs. In addition, the results of observation of this study can be used to the contents that can achieve the purpose of reorientation for mathematics teachers.

This study investigated the trends in the number of applicants and mean score and applicants’ responses on the test items of Earth Science in the College Scholastic Ability Test (CSAT) implemented for 3 years (1999-2001). The percentage of applicants of science track were 43.14% in 1995, but reduced through 29.5% in 2001 to 26.92% in 2002 CSAT For elective subject, about 22% of science track students applied to Earth Science II which ranked third to Biology II and Chemistry II. In 1999, test items were developed to have the expected difficulty 40 ${\sim}$ 59% (6 items) to 60 ${\sim}$ 79% (10 items). But in 2001 every 16 items were developed to have difficulty 60 ${\sim}$ 79%, which was caused by the policy of so called ‘easy CSAT’. Thus the mean score of ‘Earth Science II’ was increased from 50.26 in 1999 through 64.47 in 2000, to 67.58 in 2001. Applicants were generally very good at solving test items focusing on process skills only and familar items but poor at solving test items related to the motion of the earth and planets and sea wave, especially items calling two or more concepts. Thus special measures to cope with the decrease in applicants of science track should be provided. And it is recommended to develop test items with wider range of difficulty and to reduce test items calling process skills only. And special consideration should be given to teaching the content area with poor achievement and high actual difficulty compared to the expected.

지난해 11월 대입수학능력시험이 치러지고 대입전형이 시작되면서 다양한 입시 관련 정보를 제공하는 사이트들의 트래픽이 대폭 상승했다. 전에 비해 신입생 전형제도가 복잡해지면서 다양한 입시 관련 사이트들이 자세한 입시정보 서비스와 채점 서비스, 지원대학 정보등의 각종 부가 서비스를 제공 하고 있어 수험생과 학부모의 큰 인기를 끌었던것으로 분석된다. 디지털대성학원은 순방문자수가 10월 36만명에서 11월 90만명으로 2배이상 증가했으며, 전체 순위도 10월 823위에서 11월 425위로 400위 이상 큰 폭으로 상승했다. 이밖에도 씨스쿨, 에듀피아가 각각 전월대비 46만명, 36만명이 증가한 99만명, 105만명을 기록했다.

현행 대학수학능력시험에서는 영역별로 선택과목제가 본격적으로 도입되어 시행되고 있으며, 과목별 난이도의 차이를 사후적으로 보정하기 위하여 표준점수제를 도입하여 운영하고 있다. 그러나 표준점수제를 실제 운영해본 결과 적지 않은 문제점들이 드러난바 있다. 이 연구에서는 이러한 표준점수제의 문제점을 집중 분석해 보고, 이에 대한 대안으로 가산점수제를 제안하여 지난 2005 수능 결과에 적용해 보았다. 그 결과 제안된 가산점수제는 기존의 표준점수제가 갖고 있던 여러 가지 문제점들을 크게 완화하거나 해소하는 것으로 나타났다.

The purpose of this study was to investigate the cohesion-related text factors that affected the correct answer rate of the English reading section in the Korean CSAT. To this end, reading passages of the 2014-2018 CSAT and CSAT mock test were collected and analyzed in terms of cohesion. And then, correlation analysis was implemented between the results regarding cohesion and item difficulty. The conclusions were as follows. First, the correct answer rate tended to increase as the linguistic burden of learners was reduced, when specific arguments between sentences were repeated. Second, there was no statistically significant correlation between the 8 sub-area of latent semantic analysis and the correct answer rate. Finally, the pedagogical implications of this study and suggestions for further study were discussed.

본 논문에서는 서술형 수학 문제 풀이 모델의 숫자 대소관계 파악을 위한 명시적 자질추출방식 Explicit Feature Extraction(EFE) Reasoner 모델을 제안한다. 서술형 수학 문제는 자연현상이나 일상에서 벌어지는 사건을 수학적으로 기술한 문제이다. 서술형 수학 문제 풀이를 위해서는 인공지능 모델이 문장에 함축된 논리를 파악하여 수식 또는 답을 도출해야 한다. 때문에 서술형 수학 문제 데이터셋은 인공지능 모델의 언어 이해 및 추론 능력을 평가하는 지표로 활용되고 있다. 기존 연구에서는 문제를 이해할 때 숫자의 대소관계를 파악하지 않고 문제에 등장하는 변수의 논리적인 관계만을 사용하여 수식을 도출한다는 한계점이 존재했다. 본 논문에서는 자연어 이해계열 모델 중 SVAMP 데이터셋에서 가장 높은 성능을 내고 있는 Deductive-Reasoner 모델에 숫자의 대소관계를 파악할 수 있는 방법론인 EFE 를 적용했을 때 RoBERTa-base 에서 1.1%, RoBERTa-large 에서 2.8%의 성능 향상을 얻었다. 이 결과를 통해 자연어 이해 모델이 숫자의 대소관계를 이해하는 것이 정답률 향상에 기여할 수 있음을 확인한다.
