This study analysed the schemata which are requisite to understand and prove examples of mathematical induction, and examined students' construction of the schemata. We verified that the construction of implication-valued function schema and modus ponens schema needs function schema and proposition-valued function schema, and needs synthetic coordination for successive mathematical induction schema. Given this background, we establish $1{\sim}4$ levels for students' understanding of the mathematical induction. Further, we analysed cognitive difficulties of students who studying mathematical induction in connection with these understanding levels.

The mathematics curriculum revision is currently underway based on the general curriculum revised in 2009. Two of the controversial issues in mathematics curriculum revision are 'grade band' and 'mathematical process'. To consider the introduction of those two aspects in mathematics curriculum, this study compares and analyzes international mathematics curricula focusing on grade band and mathematical process. As a result, grade band is judged to be not necessary, but mathematical process has a potential to provide practical implication for betterment of mathematics textbook and lesson.

There is a close interaction between the linguistic-syntactic representation system and the affective representation system that appear in the mathematical process. On the other hand, since the mathematical conceptual system is fundamentally metaphoric, the analysis of the mathematical concept structure through linguistic representation can help to identify the source of cognitive and affective obstacles that interfere with mathematics learning. In this study, we analyzed the problem-solving protocols of mathematical gifted children from the perspective of cognitive language and meta-affect to identify the relationship between the functional characteristics of the text and metaphor they use and the functional characteristics of meta-affect. As a result, the behavior of the cognitive and affective characteristics of mathematically gifted children differed according to the success of problem solving. In the case of unsuccessful problem-solving, the use of metaphor as an internal representation system was relatively more frequent than in the successful case. In addition, while the cognitive linguistic aspects of metaphors play an important role in problem-solving, meta-affective attributes are closely related to the external representation of metaphors.

The purpose of this study was to examine and analyze the mathematical tasks in the high school textbooks. In particular, it aimed to reveal the overall picture of the level of cognitive demand of the mathematical tasks in the textbooks. We adopted the framework for mathematical task analysis suggested by Smith & Stein (1998) and analyzed the mathematical tasks accordingly. The findings from the analysis showed that 95 percent of the mathematical tasks were at low level and the rest at high level in terms of cognitive demand. Most of the mathematical tasks in the textbooks were algorithmic and focused on producing correct answers by using procedures.

The purpose of this study is to analyze the mathematical beliefs of students and teachers by Latent Class Analysis(LCA). This study surveyed 60 teachers about beliefs of 'nature of mathematics', 'mathematic teaching', 'mathematical ability' and also asked 1850 students about beliefs of 'school mathematics', 'mathematic problem solving', 'mathematic learning' and 'mathematical self-concept'. Also, this study classified each student and teacher into a class that are in a similar response, analyzed the belief systems and built a profile of the classes. As a result, teachers were classified into three types of belief classes about 'nature of mathematics' and two types of belief classes about 'teaching mathematics' and 'mathematical ability' respectively. Also, students were classfied into three types of belief classes about 'self concept' and two types of classes about 'School Mathematics', 'Mathematics Problem Solving' and 'Mathematics Learning' respectively. This study classified the mathematics belief systems in which students were categorized into 9 categories and teachers into 7 categories by LCA. The belief categories analyzed through these inductive observations were found to have statistical validity. The latent class analysis(LCA) used in this study is a new way of inductively categorizing the mathematical beliefs of teachers and students. The belief analysis method(LCA) used in this study may be the basis for statistically analyzing the relationship between teachers' and students' beliefs.

The current study investigated the relationships between mathematical knowledge for teaching and the mathematical quality in instruction in order to gain insight about teacher education for secondary teachers in South Korea. We collected and analyzed twelve high school teachers' scores of the multiple-choice assessment for mathematical knowledge for teaching developed by the Measures of Effective Teaching project. Their instruction was video recorded and analyzed with the mathematical quality in instruction developed by the Learning Mathematics for Teaching project. We also interviewed the teachers about how they planned and assessed their instruction by themselves in order to gain information about their intention and interpretation about instruction. There was a statistically significant and positive association between the levels of mathematical knowledge for teaching and the mathematical quality in instruction. Among three dimensions of the mathematical quality in instruction, mathematical richness seemed most relevant to mathematical knowledge for teaching because subject matter knowledge plays an important role in mathematical knowledge for teaching. Furthermore, working with students and mathematics as well as students participation were critical to decide the quality of instruction. Based on these findings, the current study discussed offering opportunities to learn mathematical knowledge for teaching and philosophy about how teachers need to consider students in high schools particularly in terms of constructivism.

This study is to help to understand the influence of exchange writing activity in the elementary mathematics on students' mathematical communication skill. Various technical activities had been implemented during the classes and the ideas from those activities had been interpreted into writings in the final stage of the classes. Those writings, then, were distributed to other students or teachers in order to devise a teaching model for exchange writing, which is to be applied to the 3rd grade classes and to identify the influence on the in mathematical communication skill. From this study, we could get such conclusions as follows: First, there was considerable difference between experimental group practicing exchange writing and control group engaging in normal learning activities in the progress of their mathematical communication skill (group discussion), writing skill and expressivity when examining their average communication skill using t-method. Similar trend had been witnessed when self-evaluating their mathematical communication skill. Second, when it comes to the mathematical tendency, experimental group showed a higher tendency in positiveness compared to the control group. Therefore, we might conclude that the exchange writing has a positive influence on the students' mathematical tendency, especially on their curiosity or interest in teaming, willingness to study and their comprehension of its importance.

본 연구는 학교 교육과정 가운데 특히 수학과 교육과정에 초점을 맞추고, 미국과 한국을 중심으로 수학과 교육과정의 변화를 초래한 근본적인 원인을 분석하고, 두 나라의 중학교 수학과 교육과정의 체제와 내용을 비교해 보고자 시도하였다. 이러한 비교는 교육과정의 공통성과 차이성을 찾아서 한국 교육과정의 사회적 및 개인적 적합성을 평가하고, 이후 한국의 교육과정 개선을 위한 방안들을 모색하기 위한 것이다. 이미 미국의 경우 1980 년대 들어 서면서 정보화 사회에 적응할 수 있는 수학과 교육과정의 개발 작업에 노력해 왔으며, 한국도 1980 년대 후반부터 제 6 차 교육과정의 개발을 위한 연구를 시작하였다. 그 결과, 미국은 NCTM (미국 수학교사협회)을 중심으로 새로운 수학교육의 표준을 설정하고, 향후 수학교육이 지향할 방향과 전략을 설정한 바 있다. 또한 한국은 제 6 차 교육과정 개정 작업을 통하여 1992 년에 새로운 교육과정을 고시하였다. 물론 양국의 수학과 교육과정을 비교 분석하기 위해서는 그 범위와 대상을 폭 넓게 정할 수도 있겠지만, 본 연구에서는 분석의 대상을 최근 미국의 수학과 교육과정의 근간을 이루고 있는 NCTM 의 일련의 교육 표준화 관련 연구들과 한국의 제 6 차 교육과정에 나타난 수학과 교육과정으로 제한하였다. 본 연구에서는 양국의 수학교육을 이해하기 위하여 1) 양국의 수학과 교육과정에 나타난 수학교육의 일반적 성격, 기본 방향 교육 목표를 비교 분석하였고, 2) 양국의 중학교 수학 교육과정에 나타난 교육 내용을 비교해 보았다. 이를 위해서, 본 연구는 NCTM 의 교육과정 안에 명시된 중학교 과정의 수학과 교육 목표 및 내용을 준거로 하여 한국 교육과정의 관련 내용을 분석하고 비교학적으로 해석하는 방식을 취하였다. 물론 한 국가의 교육과정 체제를 목표 및 내용 요소의 비교만으로 파악할 수 없다고 본다. 향후 미국과 한국의 교육과정을 이해하기 위한 연구들은 내용의 조직, 방법, 평가, 그리고 운영계획 등에 관한 분석으로 확대되어 시도되어야 할 것으로 본다.
