Mathematical modeling has been emphasized because it offers important opportunities for students to both apply their learning of mathematics to a situation and to explore the mathematics involved in the context of the situation. However, unlike its importance, mathematical modeling has not been grounded in typical mathematics classes because teachers do not have enough understanding of mathematical modeling and they are skeptical to implement it in their lessons. The current study analyzed the data, such as video recordings, slides, and surveys for teachers, collected in four lessons of teacher education in terms of mathematical modeling. The study reported different kinds of tasks that are authentic with regards to mathematical modeling. Furthermore, in teacher education, teachers' identities have separated a mode as learners and a mode as teachers and conflicts and intentional transition were observed. Analysis of the surveys shows what teachers think about mathematical modeling with their understanding of it. In teacher education, teachers achieved different kinds of modeling tasks and experience them which are helpful to enact mathematical modeling in their lessons. However, teacher education also needs to specifically offer what to do and how to do it for their lessons.

In this study, we suggest implications for teaching mathematical justification with analysis of 6th grade students' awareness of why they needed mathematical justification and their levels of mathematics justification in Algebra and Geometry. Also how their levels of mathematical justification were related to mathematic achievement. 96% of students thought mathematical justification was needed, the reasons were limited for checking their solutions and answers. The level of mathematical justification in Algebra was higher than in Geometry. Students who had higher mathematic achievement had higher levels of mathematical justification. In conclusion, we searched the possibility of teaching mathematical justification to students, and we found some practical methods for teaching.

This study helps infant teachers practice a constructivism-based teacher education program that supports infant mathematical inquiry activities and examines improvements in mathematical teaching knowledge, mathematical teaching initiatives, mathematical interaction, constructivism belief and mathematical teaching efficacy. Twenty two experiment group infant teachers and twenty two comparison group infant teachers were chosen at two workforce educare centers. The experiment group infant teachers participated in 18 sessions of a constructivism teacher training program for 8 weeks, but the comparison group infant teachers did not take part in the program. Pretest and post-tests were implemented for the mathematical teaching knowledge, mathematical teaching initiatives, mathematical interactions, constructivism belief and mathematical teaching efficacy in the experiment group. Independent sample t-test and ANCOVA were tested using Windows SPSS statistics 21.0. The homogeneity test for the experiment and comparison group revealed significant differences. ANCOVA was carried out after the pretest score was controlled as a co-variance. Significant differences were indicated in mathematical teaching knowledge, mathematical teaching initiative, mathematical interaction, constructivism belief and mathematical teaching efficacy. The results indicated that a constructivism-based teacher education program to support infant mathematical inquiry activities influenced improvements in mathematical teaching knowledge, mathematical teaching initiative, mathematical interaction, constructivism belief and mathematical teaching efficacy. This study proved the effects of the program based on constructivism theory content for the knowledge, skills and attitude about infant teaching of mathematical initiatives and practiced a program of exploration, investigation, application and assessment for infant teachers. The results can help infant teachers teach mathematical exploration activities and help activate infant mathematical exploration activities.

The most important aim of mathematics education is to promote mathematical thinking. In the Hong Kong primary school, mathematical thinking is usually conducted through the use of formula and working on "application problem" or "word problems". However, there are many other ways that can promote mathematical thinking, and investigation on mathematical structure by using counting is one important source for promoting mathematical thinking for primary school children, as every children can count and hence a well designed question that can be solved by counting can enable children of different abilities to work together and obtain different results.

수학 과목은 위계성이 강하기 때문에 조금씩 생긴 수학에 대한 결손은 학년이 올라갈수록 더욱 깊어지고 심화된다. 이에 수학학습 부진학생들은 수학 수업이 더 어렵게 느껴지고 흥미 는 떨어지고 있다. 교육과정도 학습자 위주의 교육을 지향하고 있지만 아직은 교사중심으로 수학수업이 이루어지며 학생과 교사 사이에 서로의 의견을 주고받을 방법이 특별히 없는 것 이 현실이다. 따라서 본 연구는 수학학습 부진 학생들의 수학적 태도를 변화시키고 수학성취 도 향상을 꾀하기 위한 방안으로써 수학일지 쓰기를 택하였다. 중학교 1학년 학생들 중 수학 성취도가 40% 미만인 학생들을 대상으로 6주간의 수학일지를 쓰기를 실시한 후 수학일지에 대한 반응, 수학성취도에 미친 영향을 분석해 보았다. 그 결과로 수학일지 쓰기가 학생들에 게 능동적이고 능률적인 학습태도와 수학에 대한 자신감을 갖게 함으로써 수학 성취도에 향상을 가져줌을 알 수 있었다.

본 연구는 수학적 모델링이 초등학생들의 수학적 문제해결력과 수학적 성향에 미치는 영향을 알아보는데 목적이 있다. 이를 위해서 초등학교 5학년 학생에게 8가지 주제로 총 16차시의 수학적 모델링 수업을 실시하였다. 그 결과, 수학적 모델링 중심의 수학 수업은 전통적인 교과서 중심의 수업에 비해서 수학적 문제해결력과 수학적 성향의 측면에서 통계적으로 유의미한 차이를 보여주었다. 또한, 수학적 모델링 활동은 학생들의 의사소통, 추론, 반성적 사고와 같이 다양한 수학적 사고를 촉진시키는 것으로 드러났으며, 학생들이 수업에 적극적으로 참여함으로써 수학에 대한 긍정적 성향을 갖게 되는 것으로 나타났다. 이와 같이 수학적 모델링 중심의 수학 수업이 초등학생들의 수학 학습에 양적 및 질적인 측면에서 유의미한 영향이 있는 것으로 나타남에 따라서 추후 초등학교에서 수학적 모델링의 적용 가능성 및 초등학교 수학과 교수 학습방법 연구에 대해 시사하는 바가 크다고 생각한다.
