Research in teachers' knowledge for teaching mathematics (KTM) has been gradually growing for the past several years. With various conceptualizations about what teachers need to teach mathematics, there have been studies to find out the relationship between teachers' KTM and their students' achievement. In this paper, I reviewed various conceptualizations of teacher's mathematical knowledge for teaching, and existing qualitative and quantitative studies about this relationship. Based on the review, I identified the challenges to studying this relationship mainly focusing on the existence of a phase-teaching practice-between teachers' KTM and students' learning. Considering the challenges that have been identified in the literature review, I proposed topics for future studies that would contribute to our understanding how the teachers' KTMare related to their students' achievement, and investigate further about whether and how teacher-student interaction in classroom is related to changes in teachers' KTM.

Reflection in teacher education is one reform effort that has taken hold in many teacher preparation programs. However, how to define it and how to foster it in a teacher's education are problematic issues. In this study, on the basis of literature review, science teachers' reflective thinking is defined as a process of thinking that deliberates on alternatives to solve conflict between one's previous knowledge/belief/practice and internal/external factors in science teaching context. Based on this definition, three types of science teachers' reflective thinking (i.e. technical reflection, professional reflection and critical reflection) were proposed. In addition, a framework of classifying the reflective thinking's types was also developed. To investigate science teachers' reflective thinking, two pre-service science teachers who majored in physics education participated in this study. The participants presented the monthly report on reflective practice, pre/post questionnaire, and education practicum journals. Individual interviews with them were conducted before and after their teaching activities. From the analysis of the data, it was possible to categorize the reflective thinking of the participants into three types. The major type of their reflective thinking was the technical reflection. However, it was difficult to find examples of the critical reflection.

이 논문은 수학적 개념의 뜻과 과 중요성을 살펴본 다음, 연구자가 소속되어 있는 한국의 대학생과 연구자가 연구년 동안 강의한 바 있는 미국의 대학생이 갖고 있는 수학적 개념의 수준에 대하여 조사하여 보고, 그 차이점을 비교하여 수학교육의 개선을 위한 시사점을 찾아보고자 하였다. 본 연구는 수학적 개념을 수학적 지식의 구성, 수학적 지식의 구조, 수학적 지식의 현상, 수학을 행하기, 수학적 아이디어의 가치 인식, 구성으로서의 학습, 유용한 노력으로서의 수학으로 분류하고 각 개념에 대한 양국 학생들의 인식 정도를 설문조사 방식으로 조사하였다. 본 연구에서 한국 학생들은 수학적 개념에 대한 7개의 영역 중에서 '수학적 지시의 현상', '수학을 행하기'를 제외한 5개의 영역에서 더 높은 수준을 보였다. 앞으로 한국의 수학교육은 수학을 실제로 행하는 활동을 더욱 강조하여야 할 것이다.

As observing the learning of middle school mathematics students for three years, I examined the relationship between students' procedural knowledge and their conceptual knowledge as they develop those knowledges in the rational number domain. In particular, I explored the implications of an unbalanced development in a student's conceptual knowledge and procedural knowledge by considering two conditions: (a) the case of a student who has relatively strong conceptual knowledge and weak procedural knowledge, and (b) the case of a student who has relatively weak conceptual knowledge and strong procedural knowledge. Results suggest that conceptual knowledge and procedural knowledge are most productive when they develop in a balanced fashion (i.e., closely iterative or simultaneously), which calls into question the assumption that one has primacy over the other.

간호학에서 간호업무를 이끌어갈 간호이론이(지식체) 필요하다는 생각은 20세기가 되면서부터 시작되었다. 하지만 아직도 간호학은 간호학 특유의 지식체가 부족하다는 지적을 받고 있다. 주된 이유는 간호 업무가 재대로 확인되지 않았고 간호업무를 이끌어갈 간호학 특유의 간호이론이 확실히 정립되지 않았기 때문이다. 따라서 간호가 독자적 학문으로서 인정받고 발전하기 위해서는 간호업무에 적용이 쉽고, 간호 업무에 바탕을 둔 간호이론의 개발이 필수적이다. 왜냐하면 간호 이론이 간호업무에 쉽게 적용됨으로서 간호학의 지식체가 발전할 뿐 아니라 환자 간호도 더욱 증진 될 수 있기 때문이다. 이 논문에서는 간호지식의 발전 단계를 시대적 순서와 배경을 덧붙여 고찰하였고 간호학에서 간호 분류체계가 발전하게 된 동기, 그리고 간호 분류체계가 환자 간호와 간호학의 이론개발과 발전에 어떻게 활용되는 가에 대해 서술하였다. 그리고 간호분류체계가 가지는 특성으로는 먼저 간호실무를 체계적으로 명명하고 분류함으로서 간호학에서 필요한 연구영역을 확인하게 하게 하고 간호학 고유의 지식체의 발전에 공헌하는 것 뿐 아니라 간호정보화 시스템의 개발, 다른 의료전문가들과의 효과적인 커뮤니케이션 수단 제공, 간호의 지속성을 유지, 그리고 간호의 효과성 연구에의 활용 등이 있다.

수학 교육에서 수학 지식의 추상적 특성으로 인하여 수학 학습에 중요한 발생적 측면으로서 “concrete“ 에 대한 학습론적인 연구가 부족하였다. 또한 구체적 감각 조작 단계에서 형식적 추상적 조작 단계로의 아동의 인지 발달을 강조하다보니 ”concrete“와 ”abstract“의 통상적인 의미가 이분화 됨으로서 수학 학습에서 모든 연령과 수준에 무관한 상보적이고 상호 작용하는 가치를 수학 교육 연구에서 잊고 있었다. 본 논문은 발생적인 그리고 구성주의적 수학 학습에서 ”concrete”가 가져야 할 새로운 의미를 제안하였다. 새로운 의미의 “concrete“는 다양한 경험과 사물 그리고 지식과의 관계 맺음을 의미하는 ”connected“와 같은 맥락을 갖는다고 보고 몇 가지 수학교육에 관련된 의의와 중요성을 제시하였다.

The purpose of this study is to find the point for improvement through the comparative analysis of the 2007 & 2009 revised science curriculum, and the NGSS of the United States with Bloom's revised taxonomy. The results of the analysis confirmed that the revised curriculum in 2009 compared to the revised curriculum in 2007 has expanded the type of cognitive process and knowledge, which promote a higher level thinking. However, the revised curriculum in 2009 has been biased to the type of specific cognitive process and knowledge in cognitive process dimension and knowledge dimension as compared to the NGSS of the United States. In the revised curriculum in 2009, the type of cognitive process such as 'analyze,' 'evaluate,' 'create,' and the type of knowledge such as 'meta-cognitive knowledge' have been treated inattentively. In addition, through comparative analysis, it was identified that the type of cognitive process and knowledge that were neglected in achievement standards were not dealt with in the learning objective of teachers' guides, either. The revised curriculum should consist of achievement standards in comparison to the previous curriculum to reflect better the goals of science education. Therefore, it is necessary to create an achievement standards including various types of cognitive processes and knowledge by improving the method of statement of achievement standards of science curriculum.

The purpose of this study was to examine the influence of educare teachers' science education knowledge and attitudes towards science on science teaching anxiety. 259 teachers of young children were recruited from 19 daycare centers and the data were analyzed through frequency, percentage, Pearson's correlations using PASW 18.0 and structure equation modeling using AMOS 7.0. The findings are as follows. First, educare teachers showed more than median scores in all science education knowledge, attitude towards science and science teaching anxiety. Second, in total 57% of the variance in teachers' science teaching anxiety was accounted for by teachers' science education knowledge and attitude towards science. This result implied that teachers' science education knowledge and attitude towards science should be improved in order to reduce teachers' science teaching anxiety.

The aim of the study presented in this paper was to explore South Korean elementary teachers' knowledge regarding educational theory in mathematics. An independent t-test and ANOVA are applied to examine elementary teachers' knowledge regarding educational theory in mathematics. Findings of this study suggest that there is a negative correlation between the teachers' knowledge regarding educational theory in mathematics and their teaching experiences as well as the teacher certification level. However, there is a little affect of the teachers' gender and educational backgrounds on the teachers' knowledge regarding educational theory in mathematics. The results of this quantitative study may broaden our understanding of the South Korean elementary teachers' knowledge for teaching mathematics, which have a deep impact on their teaching practice.

This study examined prevailing parents' knowledge of eye health for young children. 139 mothers responded to a questionnaire developed by the researchers. Mothers had general eye health knowledges regardless of their age, education level, and job, but they had less knowledges about children's eye health in some items. Therefore there is a need to develop education programs and materials for eye health as well as a need to provided for young children's parents.
