이 연구에서는 2015 개정 교육과정에 따른 초등학교 1~2학년 수학 교과서 어휘를 등급 및 유형에 따라 분석하였다. 어휘 유형은 학습 도구어, 수학 교과 특수 개념어, 수학 교과 일반 개념어로 구분하여 분석하였다. 어휘 등급별 분석 결과, 1~2학년 수학 교과서에서는 1등급과 2등급 어휘가 대부분을 차지하고 있었다. 어휘 유형별 분석 결과, 학습 도구어 중 일부 어휘가 3등급 어휘로 나타났으며, 수학 교과 특수 개념어의 경우 미등록어이거나 1등급 어휘인 경우들이 많았다. 수학 교과 일반 개념어는 2학년 교과서에서의 빈도수가 1학년 교과서에 비해 크게 증가하였다. 이러한 결과를 기반으로 수학 교과서 어휘 지도를 위한 시사점을 제시하였다.

The purpose of this study was to examine the effects of career identity on learning persistence and academic achievement, and mediating effect of utility value. To examine the effect of mediating role of utility value, we divided utility value into two types, utility value of daily matters and utility value of career. This study was conducted on 228 senior students in high school, to investigate relations among career identity, utility value, learning persistence and academic achievement in mathematics, by using the structural equation model. The results are as follows. First, career identity positively predicted learning persistence in mathematics. Second, career identity positively predicted the utility value of daily matters and career. Third, both type of utility value in mathematics positively predicted learning persistence in mathematics. Fourth, the utility value of daily matters and career, in mathematics subjects, showed differential predictability toward learning persistence and academic achievement. Both type of utility value in mathematics positively predicted learning persistence, but showed differential predictability toward learning academic achievement. Specifically, the utility value of daily matters in the near future did not predict the academic achievement, but the utility value of career in the distant future positively predicted the academic achievement. Fifth, the utility value was found to play a mediating role in the relationship between career identity and learning persistence. Based on the results of this study, implications for mathematics education were discussed.

The Korean government initiated an educational policy regulating academic acceleration in schools (e.g., regulating teaching or assessing above-grade-level content) in order to normalize public education and prevent the growth of private tutoring. To analyze whether the policy is achieving its intended goals, this study examined how high school mathematics teachers responded to the policy. The findings indicate four distinct teacher responses: the teachers would teach above-grade-level lessons in classes, but not assess them on a test; the teachers sought academic acceleration to prevent excessive private tutoring, although the policymakers thought that teachers' academic acceleration results in an excessive demand for private tutoring; the teachers were willing to teach above-grade-level content for students, but they were reluctant to teach below-grade-level content due to the time constraints; and the teachers recognized that the policy limited their curricular autonomy, even though it was intended to ensure their autonomy. Implications for mathematics teacher educators and policymakers are discussed.

본 연구는 한국교육종단연구2013의 초등학교 6학년부터 중학교 3학년까지의 학생 데이터들을 활용하여 수학 학업성취도의 종단적인 변화양상에 따른 학업적 자아개념 및 교사와 부모의 학업적 지원이 수학 학업성취도에 미치는 직·간접적인 영향력을 종단적으로 살펴보았다. 분석결과, 그룹별 학업적 자아개념은 수학 학업성취도에 긍정적인 영향력을 미치는 것으로 나타났으며, 교사와 부모의 학업적 지원은 학업적 자아개념을 매개로 하여 수학 학업성취도에 긍정적인 영향력을 미치는 것으로 나타났다. 또한, 학업적 자아개념과 수학 수직척도점수에 미치는 직·간접적인 영향력은 부모의 학업적 지원 보다 교사의 학업적 지원이 더 많은 영향력을 미치는 것으로 나타났다. 이러한 점에 따른 교육적인 함의점을 논의하였다.

본 연구는 개인별 지도에 초점을 둔 코칭(Coaching)학습법을 대학수학에 적용하여 학습능력과 성취도에서의 효과를 검증하였다. 대학수학에서 코칭학습법에 참여한 집단은 비참여 집단보다 학업성취도에서 유의미한 효과가 있었다. 또한, 학습부진 집단이 우수 집단보다, 여학생이 남학생보다 학업성취도에서 더 많이 향상되었다. 본 연구는 제한된 인원과 시간으로 인해 대학수학에서 코칭학습법의 효과에 대해 성급한 일반적 결론을 이끌어 내기에는 부족함이 있다. 하지만 대학수학에서 코칭학습법이 처음 적용되었다는 점과 수학교과에서 새로운 교수법으로서 토대를 마련했다는 것에 의미가 있다.

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.

In this study, we proposed a learning-centered DIY mathematics instruction for students to actively design instructions and developed important competencies. The research problems of this study were as follows. First, how did learning-centered DIY mathematics instruction affect math academic achievement? Second, how did learning-centered DIY mathematics instruction affect the affective domain? Third, what was the reaction of students to the implementation of the learning-centered DIY mathematics instruction? For this purpose, this study was conducted with 58 students in 2 classes of 2nd grade of 00 High School located in 00 Metropolitan City. As a result of the study, first, it could be seen that the study group that taught the learning-centered DIY mathematics instruction was very helpful in the change of mathematics academic achievement compared to the comparative group who taught the explanatory instruction based on traditional textbooks. Second, the research group showed a significant improvement in the affective domain compared to the comparison group. Third, the responses of the students in the research group through the learning-centered DIY mathematics instruction improved in a positive direction, and there were some negative responses.

학업성취도에 영향을 미치는 요인은 다양하며, 요인들이 미치는 영향 또한 복합적으로 일어난다. 학업성취도에 영향을 미치는 요인들은 끊임없이 변화하기 때문에 성장을 예측·분석하는 종단연구가 필요하다. 본 연구는 서울교육종단 연구의 2014년도(중학교 2학년)부터 2017년(고등학교 2학년)까지의 종단자료를 활용하여 수학 학업성취도의 종단적인 변화양상이 유사한 그룹으로 나누고 그룹별 수학수업 태도, 분위기, 만족도의 변화양상과 영향을 살펴보았다. 연구결과, 1그룹(1456명, 68.3%)과 2그룹(677명, 31.7%) 학생들의 수학 학업성취도는 수학수업 태도가 직접적인 영향을 미치는 것으로 나타났으며, 수학수업 분위기와 만족도는 직접적인 영향을 미치지 못하는 것으로 나타났다. 또한, 수학수업 태도가 수학 학업성취도에 미치는 영향력은 그룹에 따라서도 다르게 나타났으며, 수학 학업성취도가 높은 2그룹의 학생들은 1그룹의 학생들보다 수학수업 태도, 분위기, 만족도가 높은 것으로 나타났다. 그리고 수학수업 태도와 분위기, 만족도는 중학교 2학년부터 고등학교 2학년기간 동안 지속적으로 변화하는 것으로 나타났으며, 그 변화의 폭은 적은 것으로 나타났다.

There are concepts in calculus which are difficult to teach and learn. One of these concepts is integration. However, problem posing has not yet received the attention it deserves from the mathematics education community. There is no systematic study that deals with teaching of calculus concepts by problem posing oriented teaching strategy. In this respect this study investigated the effect of problem posing on students' (prospective teachers') academic success when problem posing oriented approach is used to teach the integral concept in Calculus-II (Mathematics-II) course to first grade prospective teachers who are enrolled to the Primary Science Teaching Program of Education Faculty. The study used intervention-posttest experimental design. Quantitative research techniques were employed to gather, analyze and interpret the data. The sample comprised 79 elementary prospective science teachers. The results indicate that problem posing approach effects academic success in a positive way and at significant level.
