This paper presents a design of a speech to sign language converter for deaf and hard of hearing people. The device is low-cost, low-power consumption, and it can be able to work entirely offline. The speech recognition is implemented using an open-source API, Pocketsphinx library. In this work, we proposed a context-oriented language model, which measures the similarity between the recognized speech and the predefined speech to decide the output. The output speech is selected from the recommended speech stored in the database, which is the best match to the recognized speech. The proposed context-oriented language model can improve the speech recognition rate by 21% for working entirely offline. A decision module based on determining the similarity between the two texts using Levenshtein distance decides the output sign language. The output sign language corresponding to the recognized speech is generated as a set of sequential images. The speech to sign language converter is deployed on a Raspberry Pi Zero board for low-cost deaf assistive devices.

This study aims to discuss the basic foundations to set levels and language skills for developing a Korean Proficiency Test for young and adolescent learners. Recently, there has been an increase in demand regarding young and adolescent learners from multicultural and overseas backgrounds. However, the current Korean Proficiency Test lacks the appropriate means to determine the Korean proficiency of young and adolescent learners with general purposes of language learning. Therefore, there is an urgent need for developing a specialized and new form of language assessment for young and adolescent learners who are exposed to a foreign language or a second language learning environment. The study examines and analyzes cases of foreign language examinations for young & adolescent learners; furthermore, the objectives and target were set based on the results of a needs analysis and in-depth interviews conducted among teachers and education officials in overseas Korean Hangeul Schools, international schools, elementary and secondary schools. Finally, the levels and language skills appropriate for the objectives of a proficiency test and target learners have been suggested.

본 연구는 외국어로서 한국어 연구 중에서 언어와 성의 문제를 분석하기 위하여 교육콘텐츠와 교사-학생의 인식의 관계를 조사하였으며, 또한 외국어 교육에 영향을 미치고 있는 성별언어의 역할을 연구하였다. 성별언어에 대한 교사의 인식과 교육콘텐츠에 대한 균형 있는 시각 및 교사, 학생의 소통은 언어습득의 효과적 결과를 가져올 수 있다. 19명의 교사와 71명의 학습자와의 인터뷰, 설문지 조사를 실시하여 교사는 89.4%가 여성언어가 존재함을 인정하였고, 학생은 49.6%가 성별언어에 대하여 차이점을 인식하고 있었다. 과거보다 언어가 중성화되고 았으며 굳이 남녀 성별언어를 구별하지 않는 이유는 여성의 사회활동 증가에 기언하는 사회적인 영향으로 보고 있었다. 그러므로 문화를 통한 언어교육이 교육콘텐츠의 역할이므로 경우와 시기에 따라 적절하게 이해되어야 할 필요가 있다. 아직 편향된 여성의 지위, 역할, 언어 등이 교재내용에 나타나 있으므로 이는 교사, 학생들의 이해와 수용이 필요하고 교육콘텐츠 개발에 반드시 반영되어야 할 부분이다.

In this paper, we try to explore basic factors that defines easy-to-learn programming language and easy-to-learn development environments for novice students who have not been exposed to computer programming language education. For these purpose, we investigate and analyze computer programming languages that are widely used in industrial environments, and present the summary and analyzed results. From the experimental results, most novice programmers understand computer programming languages in terms of procedural programming languages rather than in terms of functional programming languages or object oriented programming languages. Furthermore, we have found that, for effective education of basic level programming languages, factors of development environments are much more important than factors of programming paradigms that the computer programming languages are based on.

These days, with the emphasis on statistical literacy, the importance of communication is the focus of attention. Communication about statistics is important since it is a way of describing the understanding of concepts and the interpretation of data. However, students usually have trouble with expressing what they understand, especially through writing. In this paper, we examined preservice teachers' difficulties when they wrote about statistical concepts. By comparing preservice teachers' written responses and interview transcripts of the variance concept task, we could find the missing information in their written language compared to their verbal language. From the results, we found that preservice teachers had difficulty in connecting terms contextually and conceptually, presenting various factors of the concepts that they considered, and presenting the problem solving strategies that they used.

이 연구는 내용 중심 한국어 교육을 위해 학술어휘를 어떻게 교육할 것인지에 대한 방안으로 온라인 학술어휘 사전을 개발할 것을 제안한다. 학문 목적 한국어 학습자가 대학 수학 과정에서 접하게 되는 내용 중심 한국어 교육을 위한 학술적 텍스트에는 다양한 학술어휘가 존재한다. 학술어휘를 모르고서는 학문적 내용을 이해하거나 생산할 수 없다. 따라서 그들이 처한 교육적 환경을 고려하여 그들에게 가장 적합한 방식으로 학술어휘를 교육해 교육적 효율성을 높이는 것이 한국어 교육의 과제 중 하나가 되었다. 이에 대한 대안으로 본고는 온라인 학술어휘 사전 개발에 앞서 온라인 학술어휘 사전에는 어떠한 내용이 어떠한 방식으로 담겨야 하는지에 대한 기초 연구를 수행하고자 한다. 온라인 학술어휘 사전은 교실 안으로 한정되어 있던 교육을 교실 안팎으로 자연스럽게 연결하게 해 교육 현장이 갖는 어휘 교육의 한계를 극복하고 교육적 효과를 극대화할 수 있다.

At the present stage, the main directions of the professional position of a specialist in the implementation of English-language Education are to improve and spread the practice of learning languages throughout a person's life by involving information, communication and digital technologies in the educational process. Computerization of the educational process in Higher Education Institutions is considered as one of the first and most promising areas for improving the quality of education in Higher Education Institutions. The necessity of ensuring timely training and retraining of specialists of various profiles (in particular teachers) on the effective use of domestic and foreign electronic resources with the help of modern information technologies for the implementation of the professional position of a future specialist in a foreign-language environment is noted. The main goal of teaching a foreign language (the formation of students' communicative competence, which means mastering the language as a means of intercultural communication) is defined. The types of speech activity that cover the content of teaching a foreign language are highlighted. The main types of assessment in a foreign language are shown - current (non-classroom), thematic, semester, annual assessment and final state certification. The task of the teacher is drawn, which is to create conditions for practical language acquisition for each student, to choose such teaching methods by means of information technologies that would allow each student to show their activity, their creativity; to activate the cognitive activity of the student in the process of learning a foreign language.

This study explored variables related to Korean language education for preschool children with multicultural family backgrounds. Participants were 21 Korean language teachers and 14 women who immigrated from China, Japan, Mongolia, Philippines, and Vietnam to marry Korean men. They were mothers of children 2 to 7 years of age and had lived in Korea an average of five years. Mean age of mothers was 37(range of 30 to 43). Half had college and none had less then middle school education. They were interviewed with a series of semi-structured questionnaires. The children were reported to have a low level of vocabulary and articulation because their mothers could not provide fruitful oral language experiences. Supporting systems including family literacy were discussed.
