The purpose of this study was to investigate the effects of the Science Writing Heuristic (SWH) teaching strategy on cognitive levels, science concept understanding, argumentation and writing skills. 131 students attending to co-ed middle school were selected for the study and assigned to the experimental and comparative group. The teaching strategy using SWH was applied to the experimental group, while the traditional one led by teacher's lecturing was applied to the comparative group. The cognitive level test (SRT II) and baseline test were administered before the instruction period. The summary writing test and SRT II test were administered after instruction. The results showed that there was a significant difference between two groups in cognitive levels and science concept understanding, whole argumentation and writing skills. However, there was no significant difference in some argumentation components, including warrant, backing, qualifier, rebuttal, metacongnitive question. The results of this study showed the possibility of implementation of SWH in science classroom teaching.

This study handled underachievement issue of gifted students by developing and validating educational programs as a solution, or relief, of their academic underachievement problems. The proposed educational program was designed to enhancing reading comprehension ability of gifted students with underachievement. Based on comprehensive literature review, this study found that key issues of underachievement have to do with learning strategy, and also that learning strategy was established as 'reading comprehension strategy.' Considering diverse reading comprehension models and strategies suggested by preceding studies, the reading comprehension strategy program in Korean was customized for underachieving gifted students on the middle school level. The effectiveness of the reading comprehension strategy program as a solution to underachievement of gifted students was explored by applying the developed program to 36 identified students after school twice a week for 6 weeks, conducting pre- and post-tests that were selected to measure their reading comprehension abilities, collecting their academic achievement data before and after the intervention by this study, and interviewing students. As the results of this study, reading metacognition ability, reading comprehension skills, and school grades of gifted students with underachievement were meaningfully improved as a group. On the individual level, 12 identified students, exactly one third of the whole group of underachieving gifted students, showed so improved academic achievement as we can say they overcame underachievement based on the Supplee's definition.

One of the key success factors for Computer Supported Collaborative Learning(CSCL) environments relies on collaborative reflection. Reflection refers to the active, intellectual thinking for monitoring one's own learning process and continuous internal activities of exploring oneself for new learning experiences. Also, reflective activities are closely related not only with the individual aspect of internal exploration but also with the social aspect of learner-learner interaction. This paper suggests four essential macro-level design strategies such as (1)facilitating collaborative awareness, (2)making thinking visualization, (3)negotiation-mediated knowledge construction, (4)providing metacognitive awareness cues or Questions for scaffolding collaborative reflection in the CSCL environments and made some implications for key functional features for the design and development of system components for CSCL.

수학교육에서 학생들이 학습을 통하여 습득하여할 중요한 주제는 수학 지식과 수학을 다루는 인지적 조작 기술일 것이다. 특히 수학지식과 지식의 활용은 문제해결을 통한 학습에서 의미 있게 학생에게 나타나며 이를 통하여 수학 학습 동기를 강화하고 수학의 가치를 느끼게 한다는 점에서 중요한 의의를 갖는다. 대학수준의 수학교육과정에서도 문제해결은 중요한 수학교육의 중심 수단으로서 목적으로서 선언되어 있지만 실제 수업에서 잘 다루고 있지 못하다. 문제해결 지도에 대한 접근 방식으로 1950년대의 문제해결전략을 다룬 Polya, 1990년대의 메타인지적 접근을 강조한 Schoenfeld 및 최근의 여러 연구자들의 활발한 연구가 이어지고 있다. 본 논문에서 대학 수준의 문제해결 수업의 접근 방법을 소개함으로 문제해결 수업을 구현할 수 있는 지식을 제공한다. 특히 Schoenfeld의 문제해결 수업 모델은 수학 교육의 교실 수업으로의 구현 측면에서 갖는 다양한 함의를 제시한다.

The main purpose of this study was to develope a reflective journal and examine its effects on student's academic achievement and self-regulated learning strategies. For this study, 'a structured reflective journal' was designed through the steps of systems approach with the purpose of enhancing student's academic achievement and self-regulated learning strategies, especially meta-cognition and critical thinking. The reflective journal used in this study contained the constructive elements of (1) self-evaluation with 5 likert scale, (2) learning essay, (3) dialogue with peers, and (4) dialogue with professor. A total of 94 freshmen enrolled in one of two sections of the engineering courses(theory-based class and experiment and practice-based class) participated in the study for 8 weeks. A pre-test-post-test design was used to examine the effects of the application of reflective journal on student's achievement and self-regulated learning strategies. For the result, analysis of covariance was conducted to determine whether there were any academic achievement differences and self-regulated learning strategy differences. The results suggested that students were taking advantages of the reflective journal, and there were statistically significant differences in academic achievement in the experiment and practice-based class and self-regulated learning strategies in both classes.

This paper reports a meta-analysis of sixteen studies that evaluated the efficacy of cognitive behavioral therapy (CBT) for persistent primary insomnia. PubMed, Cochrane Library, EMBASE, CINAHL and several Korean databases were searched between January 2015 and June 2015. The main search strategy involved the terms that indicate CBT-I (Cognitive Behavioral Therapy-Insomnia) and presence of insomnia. Methodological quality was assessed using Cochrane's Risk of Bias. Data were analyzed by the RevMan 5.3 program of Cochrane Library. Sixteen clinical trials met the inclusion criteria, resulting in a total of 1503 participants. Stimulus control, sleep restriction, sleep hygiene education, and cognitive restructuring were the main treatment components. CBT-I was conducted for a mean of 5.4 weeks, 5.5 sessions, and an average of 90 minutes per session. The effects of CBT-i on total sleep time (d=-0.31), sleep onset latency (d=-0.29), awakening time after sleep onset (d=-0.55), sleep efficiency (d=-0.70), insomnia severity (d=-0.77) and sleep belief (d=-0.64) were significant. Overall, we found a range from small to moderate effect size. CBT-I also was effective for anxiety (d=-0.30) and depression (d=-0.35). The findings demonstrate that CBT-I interventions will lead to the improvement of both sleep quality and quantity in patients with insomnia.

Objective: The purpose of this study is to compare the effects of the CO-OP program using cognitive strategy on the satisfaction and high-level cognitive function of chronic stroke patients with cognitive impairment with the existing task-oriented approach training method. Method: The group randomly selects the experimental group and control group from 30 patients who suffer cognitive damage due to brain damage, and then randomly presents the Cognitive Orientation to daily Occupative Performance (CO-OP) Results: The results of the study showed a significant increase in patient performance and satisfaction, task performance, and high-level cognitive functions in comparison to those before training (p<).05) There was no significant difference in CNT testing in controls; Although there were no significant differences in overall CNT testing between the two groups, the COPM, AMPS tests showed a significant increase in the experimental group compared to the comparators (p <.05). Conclusion: The Cognitive Orientation to Daily Occupative Performance (CO-OP) Intervention Act, which uses meta-in strategies, was previously used. We were able to confirm that it could be a more effective intervention in task performance and high-level cognitive function than in the Meaningful Task-Specific Training Program (MTST).

The purpose of this study is to theoretically understand hope theory suggested by Snyder and confirm its utility in the school settings. We analyzed the survey data responded by general high school students to find clustering types of hope and mean difference of learning strategies by each type through ANOVA. Results are as follows. First, hope by cluster analysis resulted in four types. Second, hope and learning strategy showed statistically positive correlation. Especially two sub-variables of hope and meta-cognition had highest correlation. Researchers suggested the direction of a future study to investigate structural relation among hope profile, student achievement, adjustment, and etc.
