본 논문은 고등학교 교육과정상에서 학습자들이 오류를 범하기 쉽고, 어려워 하는 극한에 대해 보다 효과적인 지도방법을 제시한다. 현실적으로 교수활동은 교실이라는 공간에서 일정한 수업시간동안에 교사와 학습자와의 관계속에서 이루어진다. 그 속에서 학습자들은 주변의 세계를 관찰함으로써, 혹은 추측과 반박을 통해 시행착오적으로 사고함으로써 혹은 모순, 어려움, 불균형을 일으키는 주위환경에 동화 ${\cdot}$ 조절을 함으로써 자신을 적응시켜 가면서 학습하게 된다. 따라서 교수학적 의도가 미비한 환경은 학습자에게 획득하기를 기대하는 학습을 할 수 없게 한다. Brousseas의 교수학적 상황론에 근거하여 교육의 현장인 교실에서의 교사와 학생간의 상호작용에 따른 교수-학습의 중요성에 초점을 둔 본 논문은 Freudenthal의 역사발생적 원리에 의한 극한의 정의와 학습자의 오류수정을 위한 교수학습 전략으로 Lakatos의 발견술을 제안하였다. 또한 극한 개념에 대해 실생활에서 학습자에게 쉽게 동화 ${\cdot}$ 조절이 일어날 수 있는 학습 방법을 제안하였다.

대한민국의 대표적인 구기 종목 중 하나인 농구는 입문 시 기본 동작에 적응하고 기본 규칙을 이해하기 위해 많은 시간이 소비된다. 또한 기존 농구 학습 분야에서 평가 수행 시 평가 대상자의 실력을 정량적으로 도출하는 것이 힘들어 중 고등학교 체육교과의 수행평가에서 객관적인 평가가 이루어지기 힘들었다. 본 연구에서는 이러한 농구 학습의 한계점을 해결하기 위하여 3축 자이로 센서와 스위치가 적용된 웨어러블 시스템을 기반으로 농구 학습을 도와주는 동작인식 기법을 제안한다. 그리고 실험을 통하여 제안하는 동작인식 기법의 성능을 검증하였으며, 생활체육 활성화를 통한 국민 건강증진과 객관적인 수행평가 실현에 기여할 것으로 기대된다.

This study examined the factor structure of the Child Behavior Checklist Dysregulation Profile(CBCL-DP) for school-aged children in Korea identified differences in the level of maladjustment and problematic behaviors between the clinical group which had characteristics of CBCL-DP and the control group which did not. Confirmative factor analysis was performed on three alternative models from the literature to determine which was the most appropriate factor structure for the CBCL-DP. The result showed that the bi-factor model fit the sample data better than both the one and second-factor models. To confirm that the bi-factor model was the most appropriate factor structure, regression paths with relevant variables examined. The showed that CBCL-DP with the bi-factor model was associated with executive function difficulty as reported by parents and with school adjustment and all sub-factors of strength and difficulty as reported by teachers. The results also showed that this model had a different relationship with anxiety/depression, aggressive behavior, and attention problems than the other models. The clinical group was shown to have more executive function difficulty, worse adjustment of school life and to be less likely to engage in desired behaviors than the control group. These results indicate the CBCL-DP is more related to negative outcomes than any other factor, and that the bi-factor model was found to best fit the sample data, consistent with other studies. The early discovery of CBCL-DP can be used to provide interventions for high-risk children who exhibit emotional and behavioral problems, making its detection a significant diagnostic tool. The implications of these result, the limitations of this study, and areas for future research are discussed in this paper.

This study attempted to evaluate the effectiveness of the Supportive Project for the Priority Region of Educational Welfare Investment(SPPREWI) which has been put into action in Korea as a part of national policies for poor school children. In so doing this study aimed to test SPPREWI's legitimacy as well as whether we have to continue this program or not. In order to fulfill this research purpose researchers identified several outcome indicators of SPPREWI, which represent psychosocial and cognitive adjustment. The variables pertaining to psychosocial adjustment domain are: self-concept; depression, anxiety, and suicidal impulse; inclination of assault and indignation; delinquency; school life adjustment; and change in social relations. The variables of cognitive adjustment include recognition of self-control in learning; control strategy of learning behavior; and preparedness for job hunting. In this study the quasi-experimental group contained students from schools which are under the SPPREWI. The control group was composed of students from schools which were free from SPPREWI but under the influence of deteriorating school environment. The quasi-experimental group and the control group were compared in terms of outcome indicators presented earlier. Within the quasi-experimental group both the students below poverty-line and the students above poverty-line were divided into two groups each by the level of service use, and were compared in terms of the outcome variables presented earlier. Study results supported the argument that SPPREWI was effective generally in improving students' school adjustment. Study results also showed that the variable of 'school nurturance' played a significant role in moderating the effect of SPPREWI on a couple of outcome variables specially when schools' overall educational environment was in poor condition. Implication as well as suggestion were presented on the basis of study findings.

The purpose of this study was to understand the ways to enhance academic help-seeking by analyzing the structural relations among individual(achievement goal orientation) and contextural (teacher behaviors and classroom climate) factors known to affect help-seeking, one of the effective self-regulated learning strategies, for upper elementary students. More specifically, it explored the mediational roles of general classroom climate and student achievement goal orientation in the relation between supportive teacher behaviors and student academic help-seeking. A survey was administered to 315 fifth- or sixth-grade students in three elementary schools and the data from the survey was analyzed. Main results are as follows. First, supportive and learning-oriented teacher behaviors with high expectation related to more cohesive and positive classroom climate and more adaptive achievement goal such as mastery goal. Positive classroom climate played an important role in improving student mastery goal, and only mastery goal among different types of achievement goal orientation had a positive prediction of student help-seeking. Second, teacher behaviors significantly predicted student help-seeking through a double mediation of classroom climate and student mastery goal, which showed that classroom contextual factors and student individual factors interacted for help-seeking. These results suggest that the role of teachers as well as the mastery goal of students are important for enhancing students' help-seeking behavior as an adaptive learning strategy.

실행(practice)를 위주로 하는 전문직 교육은 실지 실습이나 임상교육등이 필수적이며 중요한 것은 주지의 사실이다. 그러나 전통적으로 대부분의 간호학교가 병원에 소속되어 있어서 간호 임상교육은 그 본 목적인 학생들의 학습보다는 오히려 병원 업무를 돕는 방향으로 잘못 전개되어왔다. 간호교육이 병원에 소속된 간호학교로 부터 학문의 전당인 대학안으로 옮겨지면서 많은 뜻있는 간호교육자들의 노력과 시도로 학생들이 고용인으로 이용되는 상황에서 탈피하여 임상교육이 학생들에게 이론적인 지식을 실지로 응용할 수 있는 복합적이고 통합적인 배움의 경험이 되도록 조금씩 발전해 가고는 있지만 아직도 바라는 만큼 이루어지지는 못하는 실정이다. 현재는 임상실습에 임하는 학생들이 기능적인 일을 반복하며 주어진 시간만을 채우는 경향이 많고 배운 이론을 대학 실습실에서 응용해 보지 못한채 직접 환자 간호에 적응하려면 지나친 불안과 긴장으로 오히려 학습에 장애가 오기도 한다. 또한 환자의 입장을 고려해 보면 그들은 안전하고 완벽한 간호를 받을 권리가 있음에도 불구하고 때로 서투른 학생들의 실습의 대상으로 노출되어 불안을 느끼고 바람직한 간호를 받지 못하는 경우가 많다. 따라서 몇 뜻있는 간호 교육자들은 임상들의 실습장소로 택하는 것은 학생에게는 부적절한 학습 환경이 될 뿐 아니라 환자에게는 도덕적, 윤리적으로 부당하다고 주장한다. 본 연구는 좀 더 잘 설비된 대학의 실습실이 급선무이고 또한 교화적이고 창의적인 실습실의 이용으로 반복적인 임상 실습의 양은 줄이는 한편 학생들의 실력이나 적용 능력의 토대를 탄탄히 하는 몇가지 교육방법을 제시하였다. 물론 제시된 시법이나 작은 그룹별 학습등은 기초 간호학실에서 많이 이용된 방법이기는 하지만 더욱 잘 응용되어야하겠고 역할 재현(role play)이나 유사 상황(simulation) 조성등의 학습 방법으로 기술적인면 뿐만 아니라 대인 관계나 면담기술 및 창의적이며 논리적인 사고의 발달등도 이루어 지리라 기대된다.학생들이 적정량의 기술과 지식을 익힌 후에 좀 더 복합적이고 통괄적인 지식의 응용 및 평가가 필요할 때 실지 임상 실습을 시도하는 것이 바람직한 것이다.

Free Learning Semester, the new education policy of middle schools in Korea, will be completely implemented in 2016. The purpose of this study was to explore the school experiences of middle-school students in the Free Learning Semester through qualitative approach. In-depth interview was conducted with 8 middle-school students from the purposive sampling. As a result of the analysis, 10 essential themes were identified. Themes were as follows: 'Struggling from the performance evaluation with biting the bullet', 'Great pressure on final examination that is only once a year', 'Inconvenience of career education experience', 'Higher level of friendship', 'Double face of discrimination and respect', 'Chance to adaptation between elementary and middle-school', 'Regret about fleeting time without thought', 'Ambivalence of freedom and suppression', 'Warm place with peer', 'Being pushed rehearsal wearing other's cloth'. In conclusion, the nature of lived experience of middle-school students in the Free Learning Semester is based on ambivalence of various aspects, but is predominant in 'higher level of friendship'. It suggested that the Free Learning Semester can be a positive alternative to existing education system that made students to compete each other. It is expected to be able to discuss the future policy direction using the result of this study which explored the nature of lived experience related to the Free Learning Semester.
