Metaphor is the main representations of teachers' practical knowledge, which can help students to understand mathematics better. Through the recording and quantitative analysis of video cases of expert teachers in mathematics classroom, there are some results after analysis: 1) Teachers use many metaphors in the classroom and most of that are structural-ontological metaphors, which takes a certain period of time. 2) Teachers use the metaphors mainly in the teaching process of introduce and explore by the form of question-answer. 3) During the process of concept teaching, the metaphors from the real-world examples can promote the students have more motivation to study. During the process of procedure teaching, the metaphors from similar materials can promote the students to understand the operational skill better.

The purpose of this paper is twofold. On the one hand it takes issue with Engstrom's claim that conceptual metaphors are propositional; on the other, it aims to demonstrate that the mathematical term 'mapping' is inappropriate for the analysis of metaphors. To my mind, the propositional analysis of metaphors, a wrong analysis for that matter, originates in the notion 'mapping' I argue that partial 'mapping' between propositional meanings and metaphorical meanings is either mental or psychological, with no concomitant 'truth' value. When concept metaphors represent propositionality, they lose metaphoricity; when they obtain metaphoricity, they are free of propositionality. The mathematical terms 'mapping' and 'proposition,' it is stressed, should be avoided in the analysis of concept metaphors like 'A is B' because they are confusing when applied to linguistic expression. 1 suggest that the term 'mapping' be replaced by phrases such as 'interaction between two domains,' projection from source-domain to target domain,' or 'understanding the properties of two domains between A and B,' etc. This would amount to proposing a pragmatic or cognitive theory of metaphor.

본 연구의 목적은 초등 수학 수업에서 사용되는 언어적 은유와 제스처 사용에 대한 사례를 분석하여 수학학습 지도 방안으로서의 은유 및 제스처의 가치를 재고해 보고자 하는데 그 목적이 있다. 본 연구에서는 2007 개정 교육과정 초등학교 6학년 1학기 7단원 정비례와 반비례 중 4차시 반비례 알아보기 단원을 주제로 한 수업에서 교사에게서 나타난 언어적 은유와 제스처를 분석하였다. 분석 결과 본 연구에서 관찰된 수학적 은유에는 기계은유와 가상적 이동은유가 있으며 제스처는 형상적 제스처, 은유적 제스처, 지시적 제스처의 형태로 관찰되었다. 이러한 은유들은 수학 수업 전반에 걸쳐 고르게 분포하여 다양한 형태로 표현되었으며 분석 결과를 토대로 수학 수업에 있어서 은유 활용의 교육적 의의를 재고해 보았다.

The purpose of this study was to investigate the nature of pre-service elementary teachers' metaphors on mathematics textbooks. Their metaphors describe individual and collective patterns of thinking and action on mathematics teaching and learning. To analyze their metaphors, qualitative analysis method based on Lakoff and Johnson's theory of metaphor (1980) was adopted. Metaphors on mathematics textbooks were elicited from 161 pre-service elementary school teachers through writing prompts. The writing prompt responses revealed three types and thirteen categories: As Type I, there were (1) 'Principles', (2) 'Summary', (3) 'Manual', (4) 'Encyclopedia', (5) 'Code', (6) 'Guidelines', and (7) 'Example'. As TypeII, there were (9) 'Assistant', (10) 'Friend', (11) 'Scale', and (12) 'Ongoing'. As TypeIII, there was (13) 'Trap'. Among these categories, 'Guidelines', 'Assistant', and 'Ongoing' were the most frequently revealed. These results indicate that the relations of mathematics curriculum, textbooks, and classrooms are not a unilateral way but should communicate with each other.

본 연구의 목적은 학생들의 흥미와 동기를 유발할 수 있는 수학적 은유를 활용하여 수업 참여에 도움을 줄 수 있는 교사의 담론 구조를 분석하는 것이다. 이러한 목적 달성을 위해 학생들의 경험과 수학적 개념을 연결하여 설명하는 교수법을 실행하는 경력 교사의 한 학기 수업을 관찰하였다. 연구 대상 교사가 한 학기 동안 수학적 개념과 문제 해결 과정에서 다양하게 활용한 은유 중에서, 일상생활과 수학적 내용을 단순히 연결하는 상황을 제외하고 은유를 활용하는 교수법 개발에 도움을 줄 수 있는 대표적인 수업 사례 2개 차시를 추출하였다. 대표적으로 선택된 2개 차시 수업은 은유를 활용하는 수업 사례 1개 차시와 은유를 활용하고 문제를 확장·적용하는 수업 사례 1개 차시이다. 분석 결과 학생들과의 소통을 기반으로 수학적 은유를 활용하는 교사의 담론 구조는 수학 교육회복을 위한 교수법 개발에 시사점을 제공할 수 있을 것이다.

Metaphors were conceived of as a figure of speech whose role consisted in merely ornamenting the language. However, with their seminal book Metaphors we live by (1980), Lakoff and Johnson have revolutionized the conception of metaphors by placing them as central to human language, thought and action. Cognitive linguists argue that humans tend to conceptualize abstract concepts, such as time, through more experiential and tangible concepts. For instance, it has been observed that the abstract concept of time is conceptualized as space in several unrelated languages. According to the Conceptual Metaphor Theory (CMT), TIME AS SPACE metaphor covers two more specific metaphors: (1) The MOVING TIME metaphor wherein the observer is conceived as a stationary entity, as in The end of the academic year is getting closer; and (2) The TIME AS A LOCATION metaphor wherein times are conceived as stationary points and the observer is conceived as moving relative to these locations, as in We are first approaching the end of the year. This paper aims at probing the validity of the CMT representations of time on the basis of an analysis of time metaphors in two languages: English and French. This analysis is conducted within the framework of CMT. The results corroborate the CMT representations of time, suggesting that in both languages the abstract concept of time is expressed in spatial terms. In English, as in French, time is conceptualized as a moving entity and as having extension in space. In both languages, time can be seen as bounded; therefore, one can perform actions within defined limits of time.

This Study takes Peirce' abduction which is Phenomenology' first reasoning mode, as a part of mathematical reasoning with deduction and induction. Abduction(retroduction, hypothesis, presumption, and originary argument) leads a case through a result and a rule, while deduction leads a result through a rule and a case and induction leads a rule through a case and a result. Polya(1954) involved generalization, specialization, and analogy within induction, but this paper contain analogy in abduction. And metaphors and metonymies are also contained in abduction, in which metaphors are contained in analogy. Metaphors and metonymies are applied to semiosis i.e. the signification of mathematical signs. Semiotic analysis for a student's problem solving showed the semiosis with metaphors and metonimies. Thus, abductions should be regarded as a mathematical reasoning, and we must utilize abductions in mathematical teaming since abductions are thought as a natural reasoning by students.

Teacher's practical knowledge is potentially relevant to the teaching practice in his/her classroom. The research explored early childhood teachers' practical knowledge of 'curriculum' via conceptual metaphors. The participants (N=348) completed a prompt, "Curriculum is like A because B" and then the metaphors were analyzed according to the procedure proposed by Moser (2000). The analysis found that 8 themes (i.e. 'educational basis', 'learning opportunity', 'educational material', 'difficulty', 'change', 'pre-determination', 'discordance', and 'reconstruction') were the underlying conceptions signified in those metaphors. The implications regarding early childhood teachers' practical knowledge were discussed on the perspective of post-modern curriculum. Moreover, it recommended the practical knowledge based approach for early childhood teacher education, and transformation of current policy for program evaluation relevant to curriculum conceptualization.

This study has two main purposes: to establish a list of source domains in the metaphors for Middle East respiratory syndrome (MERS) and to uncover ideological meanings embedded in them in Korean news reports from KBS and JTBC. The first part of this study presents metaphors such as [MERS IS WAR], [MERS IS WAVE], [MERS IS A LIVING THING], and [MERS IS A THING], which were found in the data. The latter part of this study deals with how the two broadcasting companies use these metaphors differently according to their ideologies. In the metaphor of [MERS IS WAR], KBS tends to show less of the agents who controls the war since the war against MERS has failed which casts responsibility to the controlling agents, the government and big hospitals. In this, KBS tries to present less of the information of the responsible agents that presented in JTBC. Through the metaphor of [MERS IS WAVE], KBS presents the aftermath of MERS as something not serious. Compared to JTBC, KBS tends to suggest that the aftermath of MERS is predominantly an economic effects by metaphorically suggesting that predominantly the economic sector got hit by MERS.
