The purpose of this study is to search for the direction of informal science education research by analyzing them from the educational perspectives of informal science education. For this purpose, this study analyzed 144 journals related to informal science education that have been issued in the last six years in terms of educational perspectives. As a result, this study found a tendency for studies to be biased towards a few educational perspectives such as scientific practice participation, emotional enhancement, and understanding of knowledge, while studies on the understanding of nature of science have been conducted in a few cases. This tendency was also found in the analysis of the detailed media in each field, however, the biased educational perspectives varied from media to media. Therefore, in order to understand various aspects of informal science education itself, which is not a subsidy of formal school education, and to deeply understand what each media is trying to pursue, it should be done with various educational perspectives in each media study.

CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.

There have been a number of lesson analysis studies, yet not many studies address the issue of the perspective of students who play a key role in the lesson along with the teacher. The purpose of this study is to investigate how the teacher and the students interpret the mathematics lesson they experienced, and to find out the potential discrepancy between the teacher and the students in their perceptions of mathematics lesson. To pursue this purpose, 10 consecutive lessons were videotaped in the 8th grade mathematics classroom, and the video-stimulated post-lesson interviews were also conducted with the teacher and the students. Based on the lesson videos and the interview data, six discrepancies between the teacher and the students in their perceptions of mathematics lesson were dentified: the discrepancy between the teacher's intention and students' interest in the lesson; different interpretation and response to the teacher's mistake; formal abidance; topaze effect; different recognition of the students' preference among the topics; teacher's insufficient response to students' needs. These six discrepancies were further categorized and some implications were drawn.

This study is about the Data which is one of Euclid's writing. It dealt with the organization of contents, formal system and mathematical meaning. First, we investigated the organization of contents of the Data. Second, on the basis of this investigation, we analyzed the formal system of the Data. It contains the analysis of described method of definition, proposition, proof and the meaning of 'given'. Third, we explored the mathematical meaning of the Data which can be classified as algebraic point of view, geometric point of view and the opposite point of view to 'The Elements'.

조합논리는 기본적으로 정해진 해석이 없는 순수한 형태만을 가지고 추상적으로 연산하는 관점에 관한 논리로서, 논리학을 기호학적 관점에서 볼 수 있는 토대를 제공해 준다. 조합논리의 특징은 연산자가 피연산자도 될 수 있다는 사실에 있으며 그래서 동일한 연산자가 그 자신의 피연산자도 될 수 있다. 이 논문에서 우리는 기본연산자들의 직관적 개념과 형식적 개념을 소개하고 연산자 대수에 내해 검토하고 나서 조합논리와 $\lambda$-연산의 번역가능성에 다해 알아보겠다. 조합논리에 유형의 개념을 추가하면 자연언어 분석에서 아주 효율적인데 기본유형인 대상자 명제 이외의 어떤 요소라도 함수자로 나타낼 수 있는데 이들은 조합자의 특수한 경우로서 파생유형들이다.

According to prior research studies, comparison of two data sets promote informal and formal statistical reasoning, which may mediate descriptive and inferential statistics. However, there has been relatively little attention given to the mediation of both descriptive and inferential statistics. We attempted to identify which statistical concepts or factors students used and how they applied concepts or factors to make decisions when they compared data sets. We also investigated the characteristics and changes of the view of concepts and factors. As a result, we identified that students paid attention to data value, center, spread, and sample, which are important factors of inferential statistics. Students' understanding of each factors were sometimes appropriate for inferential statistics, but sometimes not. From the results, we suggest instructional ideas for a task which can connect descriptive and inferential statistics.

이 논문은 영어와 한국어에서 나타나는 완수동사(Accomplishment Verb)와 지속부사구(durative adverbial)의 상호작용에 대해서 논한다. Smith(1991)에 의하면 완수동사가 지속부사구와 결합하면, 동사와 부사구의 의미적 자질의 충돌을 피하기 위해서 완수동사의 상변환(Apsect Shift)이 일어난다. 본 논문은 이 상변환이 영어와 한국어에서 어떻게 실현되는가를 보이고, 이를 형식의미론에서 어떻게 기술할 수 있는가를 논한다. 완수동사가 지속부사구와 결합할 때, 영어와 한국어 모두에서 닫힌 완료 관점(closed perfective viewpoint)에서 열린 관점(open viewpoint)으로 관점 변환(viewpoint shift)이 일어난다. 그러나, 한국어의 상변환과 영어의 상변환이 완전히 일치하는 것은 아니다. 한국어의 관점변환은 완료관점도 아니고 미완료 관점도 아닌, 중립관점(neutral viewpoint)으로의 변환인 반면, 영어의 관점변환은 단순히 미완료 관점으로의 변환임이 논의된다. 이 주장은 한국어의 관점변환 구문은 이질적인 다수 사건의 연속 해석(heterogeneous sequential reading of multiple events)을 허용하는 반면, 영어의 관점변환구문은 오직 동질적인 단일 사건의 동시 해석 (homogeneous simultaneous reading of a single event)만을 허용한다는 사실에 의해서 지지 된다. 본 논문은 완수동사가 지속부사구와 결합할 때 일어나는 상변환에 대한 형식의 미론 분석을 Heim ＆ Kratzer (1998)의 틀에서 제시한다. 닫힌 관점에서 열린 관점으로의 상변환은 비가시적 시제 서법 운용자(covert temporal-modal operator)인 IMP를 지속부사구의 논항으로 설정하여 설명한다. IMP는 Dowty (1979)에서 미완료상의 모순(imperfective paradox)을 해결하기 위해서 설정한 PROG를 Heim ＆ Kratzer (1998)의 틀에 맞게 수정한 것이다. IMP는 평가 세계 (evaluation world)를 현실 세계(actual world)에서 가상 관성 세계(possible inertia would)로 변화시켜서, 완수동사의 종결점(ending point)을 현실세계에서 가상의 미래 세계로 움직이는 역할을 한다. 결과적으로, IMP는 완수동사의 닫힌 완료 관점을 현실세계에서는 열린 미완료 관점으로 변환시키되, 가상 관성 세계에서는 그대로 닫힌 관점으로 유지 시키는 효과를 가진다. 한국어와 영어의 관점 변환 구문의 차이는 각 언어의 지속부사구의 어휘 목록의 전제(presupposition)의 차이로 설명된다. 본 논문은 영어의 지속부사구는 논항의 하위간격

The study tries to differentiate the levels of mathematical reasoning from inductive reasoning to formal reasoning for teaching gradually. Because the formal point of view without the relation to objects has limitations in the creation of a new knowledge, our mathematics education needs consider the such characteristics. We propose an intuitive level of proof related in concrete operations and perceptual experiences as an intermediating step between inductive and formal reasoning. The key activity of the intuitive level is having insight on the generality of reasoning. The details of the process should pursuit the direction for going away from objects and near to formal reasoning. We need teach the mathematical reasoning gradually according to the appropriate level of reasoning more differentiated.

In this paper, we deal with the teaching of algebra based on patterns and generalization. The past algebra curriculum starts with letters(variables), algebraic expressions, and equations, but these formal approaching method has many difficulties in the school algebra. Therefore we insist the new algebraic approaches should be needed. In order to develop these instructions, we firstly investigate the relationship of patterns and algebra, the relationship of generalization and algebra, the steps of generalization from patterns and levels of difficulties. Next we look into the algebra instructions based arithmetic patterns, visual patterns and functional situations. We expect that these approaches help students learn algebra when they begin school algebra.

This writing presents a structural methodology that conceptualize' Fransis Ford Coppola's perspective and adaptation style of his screenplay derived from the author Mario Puzo's original novel "The Godfather". This paper is divided into two different stages: The first stage, namely the "formal stage", encapsulates the analysis of narration and exploring the effects of structural transformations, such as deleting, creating and modifying from the novel to the screenplay. The second stage, entitled "semantic stage", is concerned with ascertaining the difference between the structure itself and the adapter's perspective on the original novel. The opening sequence of will be used as a case study to explore these issues in examining its adaptation style specifically while also offering a template for adapting a screenplay from a novel.
