김은현 한국영미문학교육학회 2012 영미문학교육 Vol.16 No.2

This article assessed the status of Korean-American children’s and young adult books published between 1970 and 2006 in the U.S. It evaluated aesthetic qualities of the books by looking at such characteristics as plot, theme, and characterization,but its major tool of evaluation was to view the books as multicultural texts. The following themes emerged: (1) immigration hardships, (2) intergenerational relationships, (3) adjusting to a new school, (4) cultural heritage, (5) adoption and interracial child stories, (6) racial prejudice/discrimination and identity, and (7)Korean history and culture. Inauthentic portrayals were still found in many of the books, such as model minority myths, misuse of honorifics, and distorted illustrations. In conclusion, this article addressed the importance of utilizing the crucial slices of Korean/Korean-American children’s social and cultural realities in literary education. This research will provide guidance on Korean/Korean-American children’s and young adult books to English teachers in Korea by examining literary and artistic qualities, representations, and diverse themes of the literature.

김은현,김래영 한국수학교육학회 2022 수학교육 Vol.61 No.3

본 연구의 목적은 정보 리터러시에 대한 수학교육 전문가들의 인식을 탐색 및 분석함으로써 이론과 현장 전문가들의 인식을 파악하고 더 나아가 수학교과를 위한 정보 리터러시를 현장에 안착시키는 방안을 논의하는 것이다. 수정 델파이기법과 FGI를 통해 나타난 전문가들의 의견을 수집하여 지속적비교방법을 통해 전문가들의 인식을 질적으로 분석하였고 그 결과 공통된 주제로 비교 분석할 수 있었다. 첫째, 대부분 전문가들은 정보처리 능력을공학적 도구의 활용과 통계 영역에 국한하여 인식하고 있었고 정보처리 능력을 확장하여 수학교육에서의 정보 리터러시의 필요성을 느끼고 있었으나그 의미 이해에 대해서는 약간의 차이가 있었다. 둘째, 현장 전문가들은 교과교육에서의 사회적 역량을 중요시하고 있었으며 정보 리터러시를 통해서도함양할 수 있다는 의견에 동의하였다. 셋째, 수학 교과를 위한 정보 리터러시가 현장에 안착하기 위해서는 교사를 지원하는 구체적인 방안이 마련되어야하며 역량 기반의 교육과정이 잘 이행되기 위해서는 현장 적용가능한 방안이 논의되어야 한다는 의견이 공통으로 나타났다. 따라서 본 연구는 수학교육 전문가들의 인식 분석을 통해 수학 교과를 위한 정보 리터러시의 필요성과 중요성을 확인하였으며 정보 리터러시를 학교수학에 적용하는 데에 이론전문가와 현장 전문가의 의견 간에 약간의 차이가 있었지만 모두 고려한 방안을 마련하고자 하였다.

Fun-Fun English : The Impact of Literature-Based Program on Students’ Interests and Performances

김은현 한국영어어문교육학회 2015 영어어문교육 Vol.21 No.4

Fun-Fun English is an after-school program that has provided elementary students with literature-based English language instruction. This research examined the impact of the program on students’ performances and interests in learning English and challenges teachers perceive in teaching literature. A qualitative case study method has been adopted, and the data has been collected from teacher interviews, classroom observations, student survey, and work samples. This study found that the program was deemed fun and interesting, enabling students to engage in English as a foreign language. Repetitive patterns in literature and diverse scaffolding strategies were the keys to provide students with language practice opportunities. However, learner differences and creating interesting activities were the major concerns for the teachers. In addition, there was a need to allocate more time for intensive study on phonics and grammar in order for students to learn English more effectively. This study suggests that for developing more effective literature-based program, how to use literature in teaching is considered important as much as literature itself. In addition, more balanced approach of incorporating both implicit and explicit teaching of language forms needs to be adopted in meaningful contexts.

김은현,박혜림 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.19

Objectives This study is to examine the effects of multicultural pre-service teacher training for the integration of multicultural and English education. It aims to study how intensive teacher training affects teaching strategies utilizing multicultural children’s literature and teachers’ multicultural attitude. It also investigates positive and negative factors in applying what they have learned from teacher training to educational contexts. Methods Mixed methods of quantitative and qualitative research methods were adopted. Attitude toward ract/ethnic diversity, multicultural understanding and attitude, English reading and writing ability were analyzed by utilizing SPSS/PC+ 21.0, and teaching journals, work samples, and interview data were also examined through phenomenological research method. Results The findings of quantitative data analysis using t-test showed that multicultural education using children’s literature positively affected both teachers’ and students’ multicultural attitude. The differences were statistically significant. Through the teacher training, per-service teachers could understand how to utilize multicultural children’s literature using culturally responsive pedagogy and how to integrate English and multicultural education. In the teaching contexts, using multicultural picture books had positive impacts on understanding diverse cultures, and positively affected students’ English reading and writing ability. Engaging with multicultural picture books gave students the opportunities to actively participate in the lessons. On the other hand, there were cases where students won’t accept different perspectives about other cultures. Some pre-service teachers also pointed out that meeting with multicultural students in the real world would be integrated into the teacher education program. Conclusions This study addressed not only the positive impacts of teacher training on implementing English and multicultural education utilizing multicultural children’s literature, but also challenges in implementing multicultural education in educational contexts. 목적 본 연구는 다문화 아동문학을 활용한 초등영어와 다문화의 통합교육을 위한 집중교사교육을 예비교사들을 대상으로 실시하고, 교사들이 배운 것을 교육실습 현장에서 적용하는 과정을 살펴봄으로써, 다문화와 영어의 통합교육을 위한 교사교육 프로그램의효과성에 대한 심층적 연구를 진행하고자 하였다. 방법 이를 위하여 양적연구와 질적연구를 통합한 혼합연구방법을 채택하였다. 양적연구 방법으로 예비교사를 대상으로 인종/민족다양성에 대한 태도 검사, 아동을 대상으로 영어읽기/쓰기능력과 다문화이해 및 태도 검사를 사전사후 실시하여, SPSS/PC+ 21.0 을 활용하여 대응표본 t 검증을 실시하였으며, 질적연구 방법으로 현상학적 연구를 통해 예비교사를 대상으로 한 개별심층 면담자료및 성찰일지를 분석하였다. 결과 첫째, 집중교사교육에 참여한 예비교사들의 인종/민족 다양성에 대한 태도 검사는 통계적으로 유의미한 차이가 있었다. 둘째, 집중교사교육을 통해 배운 것을 실제 교육실행에 적용했을 때, 긍정적 요소를 살펴보면 그림책을 활용한 수업은 학생들의 흥미를유도할 수 있었고, 참여도를 높일 수 있는 수업이었음을 알 수 있다. 부정적 요소로는 매스컴이나 부모님의 영향을 받은 다른 나라에대한 학생들의 인식의 변화를 단기간의 다문화 교육으로 이끌어 내기가 쉽지 않았음을 알 수 있다. 셋째, 실습수업 전, 후 아동의 영어읽기/쓰기능력과 다문화이해 및 태도의 변화를 살펴보면, 다문화 아동문학을 활용한 영어수업 참여에 따른 영어읽기/쓰기 능력과다문화 이해 및 태도는 통계적으로 유의미한 차이가 있었다. 결론 본 연구는 다문화 아동문학에 대한 개념, 선정, 활용방법 및 수업전략, 다문화적 역량강화 등에 대한 예비영어교사 교육 프로그램의 효과성과 후속으로 진행되는 실제 교육 현장 적용에 대한 심층적 연구를 진행함으로써 영어교사교육 연구 분야에 다문화와 영어의 통합교육에 대한 시사점을 제시하고자 하였다.

김은현,김형근,김준호,Kim, Eun Hyeon,Kim, Hyoung Guen,Kim, Joon Ho 한국섬유공학회 2013 한국섬유공학회지 Vol.50 No.2

Non-toxic, biodegradable, and biocompatible chitosan/poly(vinyl alcohol)(PVA) nanofibers were prepared by electrospinning. The nanofibers were prepared with the following weight composition ratios:100:0 (PVA homopolymer), 90:10, 80:20, and 70:30. To improve their antibacterial activity, the nanofibers were prepared with silver zeolite nanoparticles. The properties of the nanofibers at various blend ratios were investigated by differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectrometry, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) analysis, moisture regain (%), and antibacterial activity. The prepared chitosan/PVA nanofibers containing silver zeolite nanoparticles showed good antibacterial activity and excellent moisture absorption ability.

이중전기방사법을 이용한 키토산/PVA 나노섬유 웹과 필름의 제조 및 특성

김은현,김준호,Kim, EunHyun,Kim, Joon Ho 한국섬유공학회 2016 한국섬유공학회지 Vol.53 No.2

Polyvinyl alcohol (PVA) is a non-toxic, water-soluble, biocompatible, and biodegradable synthetic polymer, which is widely used in the biomedical field. As one of the most abundant natural polysaccharides, chitosan is well known for its biocompatible and biodegradable properties. Blended chitosan/PVA nanofiber webs and films were investigated for applications in the biomedical field. Pure chitosan nanofiber web, blended nanofiber web, and skin-core nanofiber webs were prepared by electrospinning. Chitosan/PVA blended films were prepared by the solution casting method. Scanning Electron Microscope photographs showed that the skin-core nanofiber web (chitosan skin, PVA core) had the best uniformity and was suitable for electrospinning. The PVA, chitosan, and blend films had better hydrophilicity and moisture regain than PVA, blend, and skin/core nanofibers. The FT-IR and DSC analyses demonstrated compatibility between PVA and chitosan. Also, nanofiber web and films with chitosan had better mechanical properties than pure PVA nanofiber web and film; the presence of chitosan reduced the tensile strength of nanofiber webs and films, but increased their Young's modulus. All nanofiber webs showed remarkably similar elongation, and chitosan was shown to reduce the elongation of films. This study concluded that blended chitosan/PVA nanofiber web and films are well suited for applications in medical materials, such as wound dressing.
