Eleven Korean learners of English took part in an experiment where the production and perception of English /r/ and /l/ in four different word positions was investigated. Overall the subjects made more errors on /l/ in both production and identification tests. The frequency of the subjects' errors was also sensitive to word positions in which the two English liquids occur. Especially the subjects made noticeably fewer errors in intervocalic medial position. It is suggested that the Korean subjects' acquisitional pattern in this particular case of foreign phone learning can be explained more by language particular 'interference' effects rather than 'universal' acoustic arguments such as those given in Dissosway et a1. (1982) and Sheldon and Strange (1982). The results of the experiment also support the minority position among second language educators that in some cases of non-native phone acquisition, learners' production abilities can be developed earlier than their perceptual abilities.

The purpose of this study was to examine the effects of young children's stay hours on kindergartens or child care centers on their language, cognition, and social development with teacher-child interactions as a mediator. For this purpose, the data from the 2013 Panel Study on Korean Children were analyzed using the GLM and pattern analysis. The results of the GLM analysis were as follows. First, the main effects of the stay hours on child development were statistically significant Second, the main effects of the level of teacher-child interaction were also statistically significant on the results of child development. Third, the moderating effect of teacher-child interaction level between the stay hours and child development were also significant. The results showed that young children's stay hours effected their language, cognitive, and social development and teacher-child interactions mediated these effects.

The current research dealt with two areas which have been at the center of attention in the field of second language acquisition (SLA): recasts and intake. Although these two are continuously discussed in many studies, not enough research has addressed how they are related. Hence, the current research sought to identify the relationship between learner intake of language forms delivered in the form of recasts in adult EFL classrooms and learner immediate responses to recasts (i.e., uptake). The data were collected from 11 classrooms. A total of 221 recast episodes were observed and learners' responses to recasts were analyzed. On the basis of the recast episodes, multiple-choice recognition tests were developed and administrated to measure learner intake of the linguistic forms targeted by recasts. The study found that a half of recasts brought about learner intake. In addition, the learners responded to recasts in many different ways and their ways of responding were closely related to their intake of linguistic forms targeted by recasts.

As Snow (1989) and Sternberg (1985) have long argued, learning, and adaptation to the learning environment or classroom context (at the levels of instructional treatment, interventionist focus on form technique, or pedagogic task) is a result of the interaction of context at each of these levels of description with learners' patterns of abilities. In this paper I argue that this is an important area of research for SLA pedagogy, as well as SLA theory development, and I review recent developments in the study of L2 learning conditions; of the abilities contributing to L2 aptitude; and of their interaction with the processes involved in successful classroom learning and practice, and propose a model of ‘multiple aptitudes’ for classroom learning based on these findings.

This is a speculative paper, describing a recently started effort to give a formal semantics to semantic annotation schemes. Semantic annotations are intended to capture certain semantic information in a text, which means that it only makes sense to use semantic annotations if these have a well-defined semantics. In practice, however, semantic annotation schemes are used that lack any formal semantics. In this paper we outline how existing approaches to the annotation of temporal information, semantic roles, and reference relations can be integrated in a single XML-based format and can be given a formal semantics by translating them into second-order logic. This is argued to offer an incremental aproach to the incorporation of semantic information in natural language processing that does not suffer from the problems of ambiguity and lack of robustness that are common to traditional approaches to computational semantics.

This study focuses on the analysis of prospective elementary teachers' representation of trapezoid area and teacher educator's reflecting in the context of a mathematics course. In this study, I use my own teaching and classroom of prospective elementary teachers as the site for investigation. 1 examine the ways in which my own pedagogical content knowledge as a teacher educator influence and influenced by my work with students. Data for the study is provided by audiotape of class proceeding. Episode describes the ways in which the mathematics was presented with respect to the development and use of representation, and centers around trapezoid area. The episode deals with my gaining a deeper understanding of different types of representations-symbolic, visual, and language. In conclusion, I present two major finding of this study. First, Each representation influences mutually. Prospective elementary teachers reasoned visual representation from symbolic and language. And converse is true. Second, Teacher educator should be prepared proper mathematical language through teaching and learning with his students.

Software architecture serves as a framework for understanding system component and their interrelationships. Software architectures can be reusable assets to achieve low costs, high productivity, and consistent quality. We have developed a software architecture design environment, called Happy Work. In this paper, we would like to present the structure and functions of Happy Work. Happy Work has two main functions. First, it provides a graphic editor for modeling of software architecture diagram. Second, it provides an ADL, called HWL(HappyWork language). HWL is a language that describes software architecture.

The number of studies on data-driven learning (DDL) has increased in recent years, and DDL's overall effectiveness as an L2 (second language) teaching methodology has been reported to be high. However, the degree of its effectiveness in grammar instruction, particularly for the goal of correcting errors in L2 writing, is still unclear. To provide guidelines for focused grammar instruction with DDL in the Japanese classroom setting, we aimed to identify the typical grammatical errors made by Japanese learners in the Cambridge Learner Corpus First Certificate in English (CLC FCE) dataset. The results revealed that three error types (nouns, articles, and prepositions) should be addressed in DDL grammar instruction for Japanese English as a foreign language (EFL) learners. In light of the findings, pedagogical implications and suggestions for future DDL research and practice are discussed.

There are a great number of difficulties without Interface Guideline, even though the utility of the web in the educational field has been increased. In spite of having a guideline there still remains problems, when the researcher develops a practical web design, because of uniformity and universality. The purpose of this research will give a good model and a guideline, developing a way of web-site assessment through psychological language. First, the researcher has to induce psychological language and recognize the relevance of the principle of device system. Second, they should build an assessment model based on an established system of classification. As a result, they recognized that an assessment model based on the system of psychological language can help in working out authentic design problems. The designer faces many difficulties when using Interface Guideline for the sake of the existing software developer because of specific terminology. On the contrary, these days, the guideline of psychological language system provides the designer with easy comprehension of language and also able to perceive problems in advance. In addition, the researcher can realize that it can be used, as a good source and data.

This study provided longitudinal examination of the Chinese learners' acquisition of Korean vowels. Specifically, I examined the Chinese learners' Korean monophthongs /i, e, ɨ, ${\Lambda}$, a, u, o/ that were created at the time of 1 month and 12 months, tried to verify empirically how they learn by dealing with their mother tongue, and Korean vowels through dealing with pattern of the Perceptual Assimilation Model (henceforth PAM) of Best (Best, 1993; 1994; Best & Tyler, 2007) and the Speech Learning Model (henceforth SLM) of Flege (Flege, 1987; Bohn & Flege, 1992, Flege, 1995). As a result, most of the present results are shown to be similarly explained by the PAM and SLM, and the only discrepancy between these two models is found in the 'similar' category of sounds between the learners' native language and the target language. Specifically, the acquisition pattern of /u/ and /o/ in Korean is well accounted for the PAM, but not in the SLM. The SLM did not explain why the Chinese learners had difficulty in acquiring the Korean vowel /u/, because according to the SLM, the vowel /u/ in Chinese (the native language) is matched either to the vowel /u/ or /o/ in Korean (the target language). Namely, there is only a one-to-one matching relationship between the native language and the target language. In contrast, the Chinese learners' difficulty for the Korean vowel /u/ is well accounted for in the PAM in that the Chinese vowel /u/ is matched to the vowel pair /o, u/ in Korean, not the single vowel, /o/ or /u/.
