This study aimed to investigate effects of peer feedback types and feedback acceptance levels on academic achievement in project-based learning. The participants were 70 middle-school students taking an English course. They were divided into corrective and suggestive feedback groups. These participants were asked to create user-created content (UCC) as an individual task and provide peer feedback on a peer's UCC in the same type of feedback group. Results showed that there were significant differences in academic achievement according to peer feedback types (corrective vs. suggestive) and feedback acceptance levels (high vs. low). In particular, the suggestive peer feedback group had higher academic achievement than the corrective peer feedback group. Moreover, the group with a high level of feedback acceptance gained higher academic achievement than the group with a low level of feedback acceptance. Moreover, there was an interaction effect between peer feedback types and feedback acceptance on academic achievement. These results indicate that peer feedback types and feedback acceptance should be considered for effective peer feedback activity. These findings provide practical implications for the design and implementation of peer feedback activity in project-based learning.

The purpose of this study was to investigate the effect of social interaction on metacognition, learning motive and academic achievement in elementary science learning. The science lessons emphasizing social interactions that is applied to this study was comprised of 5 stages, 'introduction', 'inquiry activity', 'small group emergent activity', 'large group emergent activity', 'conclusion and assessment'. The results of this study were as follows: First, applying the learning model emphasizing social interaction to the experimental group led to a significant difference between the result of the pre- and post-test, regarding metacognition, especifically those of declarative knowledge. And meaningful difference was drawn from the results of all elements in the lower category of regulation of cognition between the experimental and comparison group. Second, a significant difference was found between the pre- and post-test regarding learning motive, especially those of attention, relation, and self-confidence. Third, after applying the learning model emphasizing social interaction to the science classes of the experimental group, students' academic achievement improved significantly in the post-test, compared to the results of pre-test.

Purpose: The study sought to identify the differences in chronic diseases and physical activity in elderly women by BMI. Method: The subjects of this study were 644 elderly women 60-80-years-of-age living at home. The research instruments were physical activity levels and chronic diseases. Subjects were given a self-report questionnaire. Data were analyzed using the SPSS win program. Result: Hypertension, prevalence of diabetes mellitus and hyperlipemia were significantly different in the subjects according to body mass index, being higher in obese subjects than in non-obese subjects. Physical activity in each of the body mass index groups did not differ significantly. Conclusion: Obesity increases the risk of chronic diseases. This knowledge could help elderly women control their weight, reduce chronic diseases, and ultimately, gain better health.

Purpose: The purpose of the study was to identify the mediating effects of social support and self-efficacy between academic stress and college adjustment in physical therapy students. Design: Survey. Methods: 75 subjects were surveyed about the level of academic, Academic Stress, College Adjustment, Social Support, Self-Efficacy, and self-control. To confirm the cognitive function on brain activity were evaluated. Results: First, College students have higher academic stress and lower college adjustment. Higher social support and self-efficacy have lower academic stress and better college adjustment. Second, students with high academic stress need constant attention to increase their social support and programs to reduce academic stress. Third, students with high academic stress, low social support, and low self-efficacy can increase their cognitive strength through the brain wave thereby reducing the academic stress they are currently feeling. Conclusion: In order to improve the College Adjustment, it is considered that it is important to increase the cognitive function through brain train along with the development of a student management program that can reduce academic stress and increase social support and self-efficacy.

This study presents a teaching model to increase the participation and interest, and to improve their understanding of physical concepts of first-year engineering students taking physics(2) course at a three-year college. In the class, a team task solution based on teamwork and a peer learning method through questions and answers between participants in each team were applied so that learners could actively participate in the class to discuss and present. We examined how the activities of each team affected students' interest in subjects, motivation to learn, and the degree of understanding of physical concepts. In the team activity, students were able to actively participate through emotional sharing between learners and free questions and explanations, and it was confirmed that academic achievement was improved by comparing the final exam evaluation results with the evaluation results of the previous three years.

본 연구는 또래도우미 활동수업이 멘티의 학업성취도에 미치는 영향 및 과학에 대한 인식을 알아보고자 하였다. 실험집단은 중학교 1학년 40명이며 또래도우미는 성적이 상위 20% 이상의 학생 및 멘티는 성적이 하위 15% 이하 학생으로 구성하였다. 또래도우미 활동수업은 8주간 23차시에 걸쳐 진행하였으며 교사의 본시 수업내용 전개가 끝난 후 15~30분 동안 실시하였다. 또래도우미 활동은 멘티가 수업내용을 정리하면서 이해하기 어려운 부분을 또래도우미에게 질문하고 도움을 포함하고 있다. 그 연구결과는 다음과 같다. 첫째, 또래도우미 활동수업이 전통적인 강의식 수업보다 멘티의 과학 학업성취도 향상에 통계적으로 유의미하였다(p<.01). 반면에 또래도우미의 학업성취도는 유의미한 효과는 나타나지 않았다(p>.05). 둘째, 또래도우미 활동수업에 참가한 학생들은 과학은 어렵고 외우는 것이 많은 힘든 과목에서 실험을 많이 하는 재미있는 과목이라는 긍정적 인식 변화가 관찰되었으며 또래도우미 활동 수업에 참가하면서 또래도우미와 멘토가 친해지는 계기가 되었다고 하였다. 셋째, 또래도우미와 멘티 모두 또래도우미 활동 수업에 대한 만족도는 높은 것으로 조사되었다(p<.01). 넷째, 멘티의 적극적인 태도 및 또래도우미와 멘티의 친밀도가 높을수록 멘티의 학업성취도가 향상되었다. 따라서 또래도우미 활동수업 시 또래도우미와 멘티의 친밀도를 고려하여 모둠을 구성하면 멘티의 학업성취도 향상 및 과학에 대한 인식은 긍정적으로 유도할 수 있을 것으로 기대된다.

팬덤 문화는 오늘날 한국 청소년 문화의 중요한 측면을 나타내는 의미있는 사회적 현상이다. 그러나 기존 연구들에서는 팬덤 활동을 일종의 일탈적 현상으로 여겨, 청소년들의 팬덤 활동에 대하여 부정적인 태도를 보이는 경우가 많았으며, 팬덤 활동의 긍정적인 영향에 초점을 둔 연구는 부족한 상황이다. 이에 본 연구에서는 팬덤 활동을 오프라인과 온라인 팬덤 활동으로 구분하여 팬덤 활동 빈도가 청소년 학습시간 관리능력에 미치는 영향을 살펴보고, 그 영향이 시간의 따라 다른지에 대해 분석하였다. 분석 자료로 한국청소년정책연구원(NYPI)에서 실시하는 한국아동 청소년 패널조사(KCYPS)의 중학교 1학년 패널의 1차 년도(2010) 데이터(N = 2,206), 3차 년도(2012) 데이터(N = 2,150), 5차 년도(2014) 데이터(N = 1,911)를 활용하였다. 종속변수를 학습시간 관리능력으로 설정하고, 독립변수를 오프라인 팬덤 활동 빈도와 온라인 팬덤 활동 빈도로, 통제변수를 보호자의 최종학력, 가구 연간소득, 성별, 자아존중감, 학교적응으로 설정한 뒤 다층성장모형을 적용하여 변인간의 관계를 종단적으로 살펴 본 결과는 다음과 같다. 첫째, 팬덤 활동에 참여하는 학생들이 과반수가 넘으며, 오프라인 팬덤 활동과 온라인 팬덤 활동을 병행하는 청소년의 비율이 가장 높은 것을 알 수 있었다. 둘째, 청소년의 학습시간 관리능력은 시간의 흐름에 따라 정적 변화가 있는 것으로 나타났다. 셋째, 초깃값에서 청소년의 오프라인 팬덤 활동 빈도와 온라인 팬덤 활동 빈도는 학습시간 관리능력과 정적 관계가 있는 것으로 나타났다. 그러나 중학교 1학년에서 중학교 3학년, 그리고 고등학교 2학년으로 학년이 증가함에 따라 팬덤 활동이 학습시간 관리능력에 미치는 정적 영향 크기는 감소하는 것으로 나타났다. 이러한 연구 결과를 바탕으로 청소년들의 주요한 문화인 팬덤 활동 및 팬덤 활동의 긍정적 측면에 대한 성인들의 이해와 적절한 개입을 강조하였으며, 학습시간 관리능력 교육의 실천적 제언을 제시하였다.

The purpose of this study is to evaluate the effects of critical friends on self-esteem and the academic oral presentation ability of undergraduate students. A pretest was conducted in the first week of the semester. A pre-academic oral presentation preparation was held from the second week to the seventh week and followed by pedagogical speech activities from the eighth week to the eleventh week. The research instruments are Academic oral presentation behavior and self-esteem evaluation forms. The samples were 37 third year undergraduate students, who were purposively selected from the educational technology class at the Chulalongkorn University. The statistics used for analyzing quantitative data are frequencies, means, standard deviations, one sample t-tests, and Pearson's Product-Moment Correlations. It was found that the 37 third year undergraduate teacher students had higher self-esteem at the statistically significant level of .05 and academic oral presentation scores after the activity were statistically significant at the .05 level.
