한은지,김동화,Han, Eun-Ji,Kim, Dong-Hwa 영남수학회 2012 East Asian mathematical journal Vol.28 No.4

The conic sections is an important topic in the current high school geometry. It has been recognized by many researchers that high school students often have difficulty or misconception in the learning of the conic sections because they are taught the conic sections only with algebraic perspective or analytic geometry perspective. In this research, we suggest a way of teaching the conic sections using a dynamic geometry software based on some mathematics teaching and learning theories such as Freudenthal's and Dienes'. Students have various experience of constructing and manipulating the conic sections for themselves and the experience of deriving the equations of the quadratic curves under the teacher's careful guidance. We identified this approach was a feasible way to improve the teaching and learning methods of the conic sections.

목적 본 연구는 부모의 부정적 양육태도와 청소년의 자아존중감, 학업무기력 및 우울 간 관계를 검증하기 위해 수행되었다. 방법 이를 위하여 2018한국아동⋅청소년패널조사(KCYPS)의 중1패널 데이터의 2차년도 자료(남 1,318명, 여 1,120명)를 대상으로 구조방정식 모형을 적용하였다. 특히, 연구모형의 적합도를 검증하기 위하여 χ2값과 TLI, CFI, RMSEA 값을 종합적으로 검토하였으며, 매개효과를 확인하기 위해 Shrout와 Bolger(2002)이 제안한 Bootstrapping 절차를 따랐다. 또한 최종모형의 남녀 집단 간 차이를 검증하기 위하여 성별 다집단 동등성 검증을 실시하였다. 결과 분석결과 첫째, 부모의 부정적 양육태도는 자아존중감에 유의한 부적 영향을 미치고, 학업무기력과 우울에 유의한 정적 영향을 미치는 것으로 나타났다. 또한 자아존중감은 학업무기력과 우울에 유의한 부적 영향을 미쳤으며, 학업무기력은 우울에 유의한 정적 영향을 미치는 것으로 나타났다. 둘째, 부모의 부정적 양육태도와 청소년의 우울 간 관계에서 자아존중감 및 학업무기력의 단일매개효과와 순차적 매개효과가 유의한 것으로 나타났다. 셋째, 다집단 동등성 검증을 실시한 결과, 모든 경로에서 경로동일성이 확보되었으나, 남자 청소년집단은 여자 청소년집단에 비해 학업무기력이 우울에 보다 강력한 영향을 미치고, 여자 청소년집단은 남자 청소년집단에 비해 자아존중감이 학업무기력에, 자아존중감이 우울에 보다 강력한 영향을 미치고 있는 것으로 나타났다. 결론 본 연구는 부모의 부정적 양육태도와 청소년의 우울 간 관계에서 자아존중감과 학업무기력의 순차적 매개효과를 확인하였으며, 교육과 상담 장면에서 성별 차별화된 방안이 필요함을 제시하였다는 점에서 그 의의가 있다. Objectives This study was conducted to examine the relationship between negative parenting attitudes, adolescents self-esteem, academic helplessness and depression. Methods To this end, data from the second year of the 1st panel data of the Korea Children and Youth Panel Survey (KCYPS) 2018 were used and analyzed. In particular, the χ2 value, TLI, CFI, and RMSEA values were comprehensively reviewed to verify the fit of the research model, and the bootstrapping procedure suggested by Shrout and Bolger (2002) was followed to confirm the mediating effect. In addition, in order to verify the differences between the boys and girls groups in the final model, multi-group equivalence verification was performed by gender. Results The results of this study are as follows. First, it was found that negative parenting attitude had a significant negative effect on self-esteem and a significant positive effect on academic helplessness and depression. Also, it was found that self-esteem had a significant negative effect on academic helplessness and depression, and academic helplessness had a significant positive effect on depression. Second, the single mediating and sequential mediating effects of self-esteem and academic helplessness were found to be significant in the relationship between negative parenting attitude and depression in adolescents. Third, as a result of multi-group equivalence verification, path equivalence was secured in all paths. However, in the boys group, academic helplessness had a stronger effect on depression than the girls group, and in the girls group, self-esteem had a stronger effect on academic helplessness and self-esteem had a stronger effect on depression than the boys group. Conclusions This study is significant in that it confirmed the sequential mediating effect of self-esteem and academic helplessness in the relationship between negative parenting attitudes and depression in adolescents, and suggested that a gender-differentiated method is needed in the field of education and counseling.

문제풀이 중심 영어수업 상황에서 학생의 학습전략: 고등학교 3학년을 대상으로

한은지 ( Han Eun-ji ) 한국ESP학회 2021 ESP REVIEW Vol.3 No.2

The purpose of this study is to understand what learning strategies students in problem-solving environment where English learning is centered. In order to understand this, data are collected and analyzed through participant observation and in-depth interviews by approaching the qualitative case study method targeting three third grade high school students who are participating in problem-solving learning. The students are accustomed to the problem-solving learning and the learning strategy is divided into three stages and analyzed: before class, during class, and after class. The students use metacognitive strategies for their own English learning in that they do their homework and set goals before class. They use cognitive strategies and social strategies during class. They take notes and take classes through questions about whether their answers are right or wrong. After class, they organize the core content in their own way and show metacognitive strategies, cognitive strategies, memory strategies and compensation strategies in order to fully understand the content. Before and during class, students’ learning strategies can be identified under the guidance of the teacher, but after class, students show positive results in that they show active learning strategies on their own.

Variability of Speech Sound Production according to Phonetic Complexity in Children with and without Speech Sound Disorders

한은지(Eun Ji Han),하지완(Ji Wan Ha) 한국언어청각임상학회 2017 Communication Sciences and Disorders Vol.22 No.4

배경 및 목적: 본 연구에서는 말소리장애 아동과 일반 아동을 대상으로 조음복잡성 정도에 따른 조음오류율, 조음산출의 변이성, 조음오류의 변이성 및 반응시간의 변이성에 대한 차이를 살펴보고, 그 특성을 비교하고자 하였다. 방법: 연구대상자는 3세부터 6세까지의 일반 아동 60명과 4-5세 순수 말소리장애 아동 20명이었다. 조음복잡성 ‘고’와 조음복잡성 ‘저’에 해당하는 목표단어에 대해 각각 4회씩 산출을 유도하는 실험과제를 DmDX Display Software로 제작하였다. 조음오류율, 조음산출의 변이성, 조음오류의 변이성 및 반응시간의 변이성에 대한 지표를 구한 후, 각 연령 집단별, 그리고 말소리장애 아동과 일반 아동 간 집단 비교를 실시하였다. 결과: 일반 아동의 경우 연령이 증가함에 따라 조음오류율, 조음산출의 변이성, 조음오류의 변이성 및 반응시간의 변이성은 낮아졌으며, 조음복잡성 ‘저’보다 ‘고’에서 모든 변이성 지표가 유의하게 높았다. 말소리장애 아동은 일반 아동보다 유의하게 높은 조음오류율과 조음오류의 변이성을 보였으나, 조음산출의 변이성과 반응시간의 변이성에는 두 집단 간 차이가 유의하지 않았다. 말소리장애 집단에서도 조음복잡성 정도는 모든 변이성 지표에 유의한 영향을 주었다. 논의 및 결론: 본 연구결과는 변이성이 비일관적 음운장애 집단만의 특성이 아니라, 정상적 성숙과정과 다양한 말소리장애 집단에서도 나타날 수 있는 증상임을 시사한다. Objectives: This study investigated the proportion of articulatory errors, variation of articulatory production, variation of articulatory errors, and deviation of reaction time according to phonetic complexity in children with and without speech sound disorder (SSD). Methods: The study subjects were 20 SSD children and 60 typically developing (TD) children from 3 to 6 years of age. Subjects produced words with high and low phonetic complexity four times. Subjects’ responses were recorded using DmDX display software for measuring articulatory variability. Results: In the TD group, proportion of articulatory errors, variation of articulatory production, variation of articulatory errors, and deviation of reaction time were lower as age increased; and the four types of measures of variability were higher at the ‘high’ level than in the ‘low’ level of phonetic complexity. The SSD group showed a higher proportion of articulatory errors and higher variation of articulatory errors than the chronological age (CA)-matched children group. In the SSD group, all types of measures of variability were higher at the ‘high’ level than in the ‘low’ level of phonetic complexity as in the CA group. Conclusion: Articulatory variability is not purely a characteristic of the ‘inconsistent phonological disorder’ group, but a more general symptom of both TD and SSD children. Thus, different kinds of variables among these groups have to be more fully analyzed.

한은지 ( Han Eun-ji ),박영아 ( Park Young-ah ) 미래유아교육학회 2016 미래유아교육학회지 Vol.23 No.4

본 연구는 유아의 또래 놀이 행동, 친사회적 거짓말 이해, 또래 인기도 간의 관계가 어떠한지를 밝히고자 하였다. 연구 대상은 만 4-5세 유아 120명이었다. 또래 놀이 행동은 교사에게 설문지를 작성하도록 함으로써 알아보았고, 친사회적 거짓말 이해와 또래 인기도는 개별적인 유아 면담을 통해 알아보았다. 연구결과 또래 놀이 행동의 영역 중에서 놀이 상호작용과 친사회적 거짓말 이해, 또래 인기도 간에 정적 상관관계가 나타났으며, 놀이 상호작용과 친사회적 거짓말 이해는 또래 인기도에 긍정적인 영향을 미치는 것으로 나타났다. 또한 친사회적 거짓말 이해는 놀이 상호작용이 또래 인기도에 미치는 영향을 부분적으로 매개하는 것으로 밝혀졌다. 본 연구의 결과는 유아의 긍정적인 또래 관계에 기여하는 변인에 대한 이해를 높였다는 점에서 의의가 있다. The purpose of this study was to analyze the relationships among peer play, pro-social lies, and peer popularity of young children. The participants were 120 four- to five-year-old children. Teachers were asked to respond the questionnaires for peer play, and children were interviewed individually for pro-social lies and peer popularity. The results of this study showed that among play interaction which is one of the domains of peer play, pro-social lies, and peer popularity were positively related to one another. Secondly, play interaction and pro-social lies positively influenced on peer popularity. Finally, pro-social lies partially mediated the relationship between play interaction and peer popularity. These findings have implications for understanding the variables contributing to young children`s peer relationships.
