The purpose of this study was to investigate the characteristics of social interaction on cultural aspects, verbal interaction, and discussion maps in scientific modeling instruction on combustion in middle school. Revised-CLEQ (Cultural Learning Environment Questionnaire), verbal interaction framework, discussion maps analysis were implemented for this study. The results of study follow respectively. First, the characteristics on cultural aspects of middle school students showed cooperation rather than competition in terms of collectivism. Students' attitudes to learning science tended to depend on others' idea, and students were passive and reluctant to present their comments when they were modeling work. Second, for the characteristics of verbal interaction, they simply presented knowledge related to build a model. The response to comments and feedback was relatively few. Third, discussion maps showed a lot of interaction for reponses that was alternatively brought the concept of commenters, which students were depended on a specific one, and responses. There were not many interaction for elaboration, which were described to have new presented ideas, corrections, and reasons when they exchange their ideas. In this study the model type of interaction affecting the formation of the students understanding of and in our country, it makes a lot of social interactions as the basis for teaching system could be utilized.

사람들은 모국어가 아닌 다른 언어를 배울 때 대부분 단어, 문법 등에 많은 부담을 느낀다. 그리고 이런 부분이 언어를 습득하는데 흥미를 반감시키고 쉽게 포기하게 하기도 한다. 다른 언어와 마찬가지로 프로그래밍 언어 또한 문법이 복잡하면 배우는 사람이 쉽게 지치기 마련이다. 이 논문에서는 프로그래밍 언어의 어휘적, 구문적 요소를 이용해 몇 가지 프로그래밍 언어의 크기를 비교하고, 어떤 언어가 프로그래밍 언어를 처음 배우는 사람에게 적합한지 보여준다. 그리고 어떤 순서로 프로그래밍 언어를 배우는 것이 효과적인지 프로그래밍 언어의 크기 측면에서 분석한다.

This study analyzed the introduction of addition and subtraction, including the composition and decomposition of numbers in the Korean, Singaporean, American, and Japanese elementary mathematics textbooks. The analytic foci of this study included visual models and their connections with the given problem contexts, the introduction of addition/subtraction or addition/subtraction sentences and their connections with the visual models, and additional activities for students to develop a relational understanding of the equal sign. The results of the analysis demonstrated diverse connections, mainly because the problem contexts, visual models, and the introduction of addition/subtraction or addition/subtraction sentences were implemented differently for each textbook. There were differences among the textbooks in what order of problem contexts were presented. Regarding the use of visual models, two textbooks tended to use one model consistently, whereas the other textbooks used various models depending on the problem contexts. There were subtle but significant differences in introducing addition/subtraction or addition/subtraction sentences. For a relational understanding of the equal sign, all textbooks included activities emphasizing that both sides of the equal sign are equal. Based on the results of this study, this paper closes with several implications related to the problem contexts to introduce addition/subtraction and addition/subtraction sentences as well as the use of visual models, which can serve as a basis for a new unit for the subsequent textbook.

Modern society is complex and rapidly changing, and knowledge sharing is needed to acquire and create knowledge. Knowledge sharing is the act of providing information knowledge and know-how of their own in order to cooperate with or help their colleagues. This study presents a research model using social capital theory to explain the mobile knowledge sharing behavior of virtual community members. Based on previous studies, social capital theory is divided into structural, relational, and cognitive aspects. It was composed of social interaction ties as a measure of structural aspect, trust as a measure of cognitive aspect, shared language, shared vision and relational aspect. After collecting survey data, factor analysis and regression analysis were performed using SPSS 22. In this way, we examined how the detailed factors of social capital affect information sharing behavior and how the level of knowledge sharing affects community promotion. The results showed that social interaction ties, shared language, shared vision, and trust affect knowledge sharing. Knowledge sharing has had a positive impact on community promotion.

This study investigated the effects of the instructions using analogies in learning the concept of saturated solution by the analogy presentation types and the verbal learning styles upon the mapping understanding, the mapping errors, and the perceptions of the instruction. Fifth graders (N=123) at an elementary school were selected and assigned to VA (n=63) and VPA (n=60) groups. As a pretest, a test on the verbal learning style was administered. The students in the VA group learned the target concept with a verbal analogy, while those in the VPA group learned it with a verbal/pictorial analogy. After the students learned it, a mapping understanding test was administered. The students in the VPA group also administered the test on the perceptions of the instruction and some of them were interviewed in depth. The results revealed that the scores of the students with strong verbal learning preference in the VPA group were significantly lower than those in the VA group in the mapping understanding test. However, the scores of the students with weak verbal learning preference were not significantly different between the two groups. Five types of mapping errors were identified: failure to map, mismapping, rash mapping, impossible mapping, and mapping of a surficial feature. According to students' verbal learning styles, there were some differences in the frequencies of mapping errors in the two groups. Many students in the VPA group, regardless of their verbal learning styles, had positive perceptions of the instruction in various cognitive and motivational aspects. However, some of them also pointed out a few difficulties of the instruction. Educational implications of these findings are discussed.

최근에 음성언어장애에 대한 언어치료사의 평가 및 치료 활동이 활발히 이루어지고 있으나, 음성평가 기준 및 치료 자료가 충분치 않은 것이 현실이다. 음성 평가를 실시할 때에도 각 치료실마다 음성 평가에 사용하는 장비가 달라 결과물의 해석에 다소 차이가 있으며, 또한 같은 장비를 사용함에도 불구하고 음성 자료를 수집하는 방법에 있어서 표준화된 절차 및 자료에 따라 평가를 하지 못하고 있는 실정이다. 이러한 표준화된 측정절차에 대한 요구는 개인적인 기준으로 좌우될 수 있는 주관적인 평가에서는 더욱 절실하다. 음성의 지각적 평가에서 중요한 측면 중에 하나는 음성의 질에 정확한 판단 및 이에 대한 자료공유 및 정보교환이다. 현재 음성의 질에 대한 측정평가를 위해 제일 많이 사용되고 있는 방법 중 하나가 GRBAS 방법이 간편하여 임상적으로 많이 사용하나 음성의 질에 대한 세밀한 평가를 하는 데는 한계가 있다. 따라서 본 연구에서는 음질을 평가하는데 있어서 자주 사용되는 음질 용어에 대한 우리말 용어를 통일의 필요성의 시급한 실정에 기초하여 이를 대표할 수 있는 음성샘플 자료의 구축마련을 위한 일종의 발제이다. 이러한 작업을 통해 각 음성 및 언어치료실에서 음성의 질에 대한 청지각적 평가에 공통 기준을 마련하고, 임상교육 적인 목적으로 청지각적 훈련 자료로 이용이 가능할 수 있으리라 사료된다.

This study tried to analyze symbolism of the work from the title by looking into its linguistic meaning. The title not only exposes artist's thoughts but also speaks for the work subject. Also, it designates the world composed of characters in the work, and further it can be said as endowing overall meaning on the entire work by suggesting possibility of limitless meaning invention as well. As a result of reviewing the symbolism shown at the title after analyzing such points through linguistic contexts, the title named with Adam's language was used for just expressing the essence of characters in the work by transcending time and space, and the title meaning exposed relational aspects between characters and occurred accidents through the association process on 'signifiant' and 'signifie.' These relational aspects are expressed to mutual contraposition, but their relations finally show another one orientation too. In case of the title made by the arbitrary nature of language, a fact could be known that it was results of customs completely unrelated with the practical work and depended on the experience by any accident as being appeared from cultural background of the country where the work was produced. Also, the signification of language occurred in unique regulations and systems, and it was relevant to seeing things through concepts. The proper noun was disappeared, and the symbolism was given again from relational aspects accordingly. It was turn out that similarity between the work and title contained contents of entire work, and played a role of expressing greed in the narrative briefly.

영어 논술 자동 평가 시스템은 수험자가 쓴 에세이에 대하여 전문 평가자가 직접 읽고 평가하는 방식에서 벗어나 웹상에서 자동으로 평가 받을 수 있는 실시간 시스템이다. 하지만 비영어권 수험자에게는 논리력 혹은 작문 능력보다 그것을 영어로 표현하는 유창성에서 더 큰 문제가 있을 수 있는데 기존 연구에서는 이런 측면에 대한 평가가 부족하였다. 본 연구에서는 보다 정확한 비영어권 수험자의 영어 논술 평가를 위해 어휘력, 문장 구조의 다양성, 문장의 혼잡도를 평가하여 언어 유창성에 집중된 기계학습 방법의 추가적인 자질을 제안한다. 실험 결과 전문 평가자의 점수와 1) 상관관계 2) 정확도 측면에서 제안하는 방법은 기존의 방법에 비해 더 나은 성능을 보였다.
