Hyoungbum Kim 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.11

With the recent advancements and developments of various media applying new computing technology, smartphone application contents are recognized as new educational media that can develop learners’ space perception ability. Spatial perception ability (SPA) is a popular research subject that is being actively being studied among earth science education scholars using augmented reality. The purpose of this study is to investigate how an astronomy education program using smartphone applications improves 6th-grade students’ space perception ability. Results suggest that the astronomy education program using smartphone applications effectively increased spatial perception and students’ scientific attitudes. Through the results of the research, it was possible to know that the creative experiences using the smartphone applications was positively influential to the enhancement of the spatial perception ability and scientific attitude and problem solving ability of sixty 6th grade elementary school students.

This study aimed to develop a tree ring-based creative education program focusing on the elements of "Ecosystem and environment" in the 2015 revised science and education curriculum and find out the effectiveness. To conduct the study, 50 randomly sampled high school students were analyzed for their creative problem-solving ability and their satisfaction with the creative education by applying the creative education program developed in this study. The results of the study are as follows. First, this study showed significant statistical test results (p<.05) from constructs: discovery and analysis of problems, idea generation, execution plan, execution, persuasion and communication, and innovation, in the paired samples t-test by pre-and post-score differences in creative problem-solving tests (p<.05), In other words, the education program centered on the theme of "a tree ring that records the environment" had a positive impact on the creative problem -solving of research participants. The figure of the sub-constructs of the satisfaction test, conducted after the application of the class, was 3.82 to 4.46, and it indicated that the creative education program developed in this study showed a positive response to students. In particular, in response to the class 'differentiation' construct, research participants responded to self-thinking activities without answers, which showed the fact that one could think by oneself and one's ideas could be an answer since there doesn't exist a correct answer has improved the participants' satisfaction of creative education classes.

김미모아(Mimoa Kim),정진우(Jinwoo Jeong),김형범(Hyoungbum Kim) 한국콘텐츠학회 2015 한국콘텐츠학회논문지 Vol.15 No.3

이 연구의 목적은 초등 과학 영재 학생들을 대상으로 과학박물관 탐방학습을 실시하여 관찰의 유형을 분류하고 이를 분석하였다. 이를 위해 과학 영재 학생 10명을 선정하여 탐방학습이 진행되는 동안 일어나는 관찰을 언어로 표현하도록 하여 모든 관찰 내용과 대화를 녹음하였다. 그 결과는 다음과 같다. 인지적 측면에서는 응답의 빈도가 높았고 자신의 의견을 배제하고 전시물과 관련하여 질문하고 응답하는 빈도가 높았으며, 정의적 측면에서는 권유의 빈도수가 가장 많았다. 관찰의 유형을 분류하고 이를 분석한 결과에서는 단수의 관찰 대상 전체를 시간 독립적으로 관찰하는 빈도가 높고, 시각을 사용하여 조작을 하지 않고 정성적인 방법으로 관찰하는 빈도가 높았다. 따라서 질문을 통한 언어적 상호작용은 관찰의 빈도와 다양성에 긍정적인 영향을 주며, 과학박물관 탐방학습에서 과학 영재 학생들의 다양한 관찰을 유도하기 위해서는 프로젝트 학습과 같은 특정 전시관이나 전시물을 학생이 직접 선택하여 집중 탐구할 수 있는 시간이나 학습지를 마련하면 더 효과적인 관찰 학습이 이루어질 수 있을 것으로 보인다. The aim of this study was to categorize and analyze the patterns of the observation type in the experiential learning through the science museum for elementary gifted students in science. Ten science-gifted students were included and analyzed in this study and during experiential learning in the science museum, the participants freely expressed their observation of their own languages and all observations and dialogue were recorded. The results are listed below. The cognitive aspect, especially question and response activity without their personal opinion, was the most frequently used item. Among the affective aspects, item for ?recommendation? was often used. In accordance to observation type, most participants overall observed single object independently of time. Also, participants mostly observed objects visually using qualitative method without manipulation. Therefore verbal interaction through question might have a positive effect on frequency and diversity of observation. Project learning, such as particular exhibition hall, exploratory time of concentration by students, or study paper will be capable of creating a effective observation learning in order to induce a variety of observation of science gifted students in the experiential learning through the science museum.

서울 지역 강수의 다중 황 동위원소(δ<SUP>34</SUP>Ssulfate, Δ<SUP>33</SUP>Ssulfate & Δ <SUP>36</SUP>Ssulfate), 질소 동위원소(δ<SUP>15</SUP>Nnitrate & δ<SUP>18</SUP>Onitrate) 및 스트론튬 동위원소(<SUP>87</SUP>Sr/<SUP>86</SUP>Sr)의 조성을 분석하였다. δ<SUP>34</SUP>Ssulfate 값은 1.9~14.6‰ (with a median of 4.7‰)의 범위를 보이며, δ<SUP>15</SUP>Nnitrate 값은 -2.0~13.3‰ (with a median of 1.0‰)의 범위를 보인다. 이러한 값은 화석연료의 사용이 황과 질소의 주요 공급원임을 지시하며, DMS 및 해수기원 황산염 등의 자연발생 공급원의 기여 역시 있었음을 확인할 수 있다. 겨울철에 높은 값을 보이는 δ<SUP>34</SUP>Ssulfate 및 δ<SUP>15</SUP>Nnitrate 값은 중국 지역에서 가정용 난방을 위해 사용되는 석탄의 사용 증가와 연관되어 있는 것으로 여겨진다. δ<SUP>18</SUP>Onitrate 값은 계절 변화를 보이며, 이는 NOx 산화 과정의 변화에 의한 것으로 생각된다. <SUP>87</SUP>Sr/<SUP>86</SUP>Sr 비는 0.70988~0.71487 (with a median of 0.71073)의 범위를 보이며, 최소 세 가지 공급원(규산염질 입자, 탄산염질 입자 및 인간활동 기원 물질)의 영향이 있었음을 지시한다.

Smartphone Service Recovery According to Gender in Korea

Hun Choi,Hyoungbum Kim 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.7

The recovering trust with service failure is very important in business area. Service failure could be causes of incomplete service or employee’s improper response. Although the recovering trust is important in smartphone application, few studies examine how recovering trust influence according to gender. This study investigates the process of recovering trust. The study conducted survey to verify the proposed research based on the theory such as justice, trust, gender etc. The result of the study reveals that the process of recovering trust varies depending on the gender which is one of the key factors that determines users’ behavior.

이 연구에서는 오프라인과 온라인의 융합 수업 전략으로 블렌디드 러닝 교수 · 학습 방법론을 적용한 HTE 창의교육 프로그램을 개발하였고, 이에 대한 중학생들의 창의적 문제해결력에 미치는 영향을 알아보았다. 이에 대한 결과는 다음과 같다. 5개 교과의 창의교육 실천 프로그램을 적용한 결과 창의적 문제해결력의 하위구인인 ‘아이디어 수정’, ‘이미지화’, ‘비유’, ‘아이디어 생성’, ‘정교성’ 의 경우 통계적으로 유의미한 차이(p < .05)를 보였으며, 전체 중학생들의 창의적 문제해결력의 사전 · 후 평균이 3.65점에서 3.79점으로 .14점 향상되어 중학생들의 창의적 문제해결력에 긍정적인 영향을 끼친 것으로 파악되었다. 또한 창의교육 프로그램에 참여한 중학생의 72%가 ‘만족한다’는 반응을, 68%가 ‘흥미롭다’라는 응답을 주었다. 이 연구결과에 따라, 블렌디드 러닝을 활용한 HTE 창의교육 프로그램은 COVID-19 상황과 다양한 창의형 인재가 필요한 4차 산업혁명 시대에 맞춤형 수업 전략으로 그 의미가 크다고 볼 수 있다. 이 연구의 제언으로 외적타당도의 일반화를 위해서는 다양한 학년과 위계에 맞는 창의교육 프로그램의 개발과 현장적용이 필요할 것으로 판단된다. This study investigated the effects of the HTE creative education program, which applies blended learning methodology as a convergence class strategy between offline and online, on middle school students’ creative problem solving capability. As a result of applying for five creative education practice programs in the classroom, it turned out that there was a statistically significant difference (p < .05) in the case of idea manipulation, visualization, comparison, idea generation, and deliberation, subordinate constructs of creative problem solving capability. Also, the program turned out to be positively effective, with a 0.14 point improvement in the pre and post-means of all middle school students, showing from 3.65 to 3.79 points, and 72% of middle school students who participated in the program were satisfied, and 68% were interested. According to the results, HTE creative education programs using blended learning turned out to be effective as a customized methodology in the COVID-19 situation and the era of the 4th Industrial Revolution, where various creative talents are needed. Therefore, the need for the development of creative education programs on various related topics and teacher training for teaching and learning methodologies of blended learning.
