The purpose of this study is to examine the effect of SNS use by prospective early childhood teachers in PBL class on flow and problem-solving skills. For this purpose, the PBL class was conducted for eight weeks with 44 prospective students in the early childhood social studies course, and measured the classroom situation in terms of usefulness of SNS, flow, and problem-solving skills by using a cognitive test. To analyze the measured values, frequency analysis, reliability analysis, factor analysis, and correlation analysis were performed. Also, to verify the hypotheses set in this study, structural equation modeling was used based on AMOS. The result is as follows: First, in PBL-based class, use of SNS had a positive effect on flow. Second, flow had a direct influence on problem-solving skills. Third, however, use of SNS did not have a direct influence on problem-solving skills and, therefore, flow plays a mediating role for problem-solving skills. Based on the result, in the study, it was found that the use of SNS in PBL class can increase interest, motivation, and participation of students and they then become more willing to contribute to class activities.

Intellectual disability affects all spheres of the lives of people can be who suffer from it. Unfortunately, modern medicine cannot cure intellectual disability. However, the quality of life improved by means of physical exercise. In this study, we compared the health-related physical fitness, metabolic syndrome index and mental health between a game biking group(5 participants) and a brisk walking group(4 participants). This study used a between-subject design and verified by non-parametric test. The participants performed an exercise program with warm up and resistance training for 12 weeks. A game bike was used for the physically impaired, where the individual looked at a screen and pedaled. The fasters he pedaled the faster the object on the screen movies. We measured health-related physical fitness, metabolic syndrome index and mental health. We also measured their perceived exertion and interest during the exercise by a visual analog scale. The results before and after the exercise program showed that health-related physical fitness, metabolic risk factors, mental health level were improved in both groups. As we hypothesized before the study, the game biking group showed a statistically significantly different level on the Rating of Perceived Exertion than the brisk walking group and a higher level on the Rating of Exercise Interest during the exercise program. Our results lead to a conclusion that an exercise program with the use of a game bike improve motivation for exercise participation in intellectually handicapped participants.

As a design research, this study aims to identify students' collaborative problems solving patterns using the Wiki and design factors triggering MKB(mathematical knowledge building) in virtual environment. For 70 days, 14 Korean secondary gifted students, who enrolled in calculus II courses in one of gifted institutions in Korea, solved 10 math problems together using the Wiki. In this study, I considered five design factors; motivation, practice of LaTeX, norms of participation, epistemic agency, and two types of educational settings. The primary pattern emergent in students' collaborative problem solving process is identified as 'solutions and refutations' along the double helix consisting of the constructive line and the critical line, which is very similar to the pattern of 'Conjectures and Refutations'(Lakatos, 1976). Despite that most participants had difficulty in using LaTeX for mathematical expressions, this study shows that Wikis are valuable tools for providing Korean secondary students opportunities to learn social virtue such as humility and courage (Lampert, 1990), which is considered to be have been neglected in Korean educational environment but is emphasized as precious for doing mathematics in the field of mathematics education.

Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) lower extremity patterns combined with elastic bands applied to stroke patients diagnosed with hemiplegia through self-training using the non-paralyzed side approach and the paralyzed side approach, and to investigate the differences in the effects. Methods: Nine chronic stroke patients who were being treated not more than twice a week at H, K, R, and C hospitals located in Gangwon-do, performed self-training for 16 minutes, two times per day for four weeks between August and October 2015. The subjects' balance ability was measured using the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and the Timed Up and Go (TUG) test before the experiment and four weeks later. Among the statistical methods, paired t-tests were conducted for intra-group comparison of the measurements taken before and after the experiment, and independent t-tests were conducted for inter-group comparison of the ex post facto values. The statistical significance level was set to 0.05. Results: When the lower extremity patterns were applied to the non-paralyzed side group and the paralyzed side group, significant intra-group differences were observed for the Tetrax stability index, the weight distribution index, the Berg Balance Scale (BBS), and Timed Up and Go (TUG) tests (p<0.05); however, the inter-group comparisons showed no significant differences. Conclusion: The non-paralyzed side approach was found to be easy for patients to participate in and it also affected the patients' paralyzed side. Although the paralyzed side approach produced good exercise effects in a short period of time, it could result in adverse effects, such as a decrease in motivation and self-confidence. Therefore, these approaches are considered to be more effective when they are selectively applied depending on the purpose of the intervention and the degree of a patients' participation.

The purpose of the study was to investigate the generality and applicability of Team-Based Learning model in a technical high school, based on the interviews with students and a teacher. Team-Based Learning model seems to be an effective way in improving the performance of groups as well as the individualized learning and team interaction. We applied a formative research method and identified the strengths of the model including learners' motivation and interests, learner-centered learning, self-efficacy through learning in advance, and concept acquisition from the repetitive learning process. However, we also found the weakness of the model including impracticality of instructional design, a lack of field-oriented problem banks, and needs for identifying learner characteristics and role in instruction. Finally, we analyzed the implications for the Team-Based Learning in the technical high schools in light of team formation, discussion types, active participation, and learners' prior knowledge and attitude, and pre-determined instructional design.

The aim of this research is to find out how convergent operation of the learning coaching and compensation system affects the academic self-efficiency and learning performance of university students. In the second semester, a compensation system was prepared based on learning coaching and learning outcomes, made a notice in advance, and conducted a survey before and after operation to measure the academic self-efficacy. In addition, the MLST-II Learning Strategy Diagnosis Examination was conducted on G university students to diagnose the learning tendency. As a result, although G University students felt a reluctance by coaching the learning community and expected negative results during the course of participation in the learning community due to low motivation and low expectation of results, they showed a significant improvement in academic self-efficiency and learning outcomes. Therefore, even students with negative learning tendency will need to consider how to operate these programs in the educational field, as the expert's learning coaching and compensation systems produce positive results for students' academic self-efficiency and learning outcomes rather than leaving them to autonomy.

One of difficulties with which teachers meet is to have underachievers with no willingness and motivation for study involved in class. Mathematics underachiever are average or above average in their intelligence but their actual achievement in mathematics did not coincide to their intellectual capabilities. The teaching strategy for them is to motivate them to try to study mathematics and to experience the improvement in their mathematics grade. In this paper, we choose flipped classroom as the strategy of teaching basic mathematics to math underachievers and applied it to them. Then we wanted to make sure the possibility for applying flipped classroom to teaching math underachievers through the analysis of change in the scholastic achievement of students in mathematics and mathematical disposition. The results of this study are as followings; First, when we taught basic math to underachievers using a flipped classroom, we confirm that math underachievers with active participation improved scholastic achievements significantly. Second, the flipped classroom was led to positive effects in an affective domain. In particular, it showed the most noticeable change in the area of willingness to math problem-solving and perception about the value of mathematics.

The purpose of this study is to identify how education and activities of urban forest healing programs affect emotional rest (healing recovery environment awareness, restoration of attention, and leisure life satisfaction). To this end, 38 people were divided into experimental groups (forest healing program education and practice), and control groups (non-program participation). As a result of the study, in the case of the experimental group, emotional rest factors such as healing recovery environment perception, attention recovery, and satisfaction with leisure activities after the program were statistically significantly improved, and in the case of the control group, there was no change in emotional rest after the program. In addition, there were differences between groups in both pre and post regarding the difference in emotional rest between the participant groups, and the difference in emotional rest afterwards was much larger than the pre-difference. In conclusion, people who receive regular education on forest healing and have done actual forest healing activities experience higher emotional rest than those who do not. This suggests that continuous motivation and regular practice can raise awareness of the healing recovery environment, promote attention recovery, and have a positive effect on leisure life through appropriate programs rather than simply taking a walk.

This study conducted non-equality control post-design similar experimental study in order to investigate the effect of self-directed practice through self-reflection by using videos on the basic nursing performance ability, confidence in performance, learning self-efficacy, and practice satisfaction. The experimental group was 57 students and the control group was 56 students in the Department of Nursing in G region. The data was collected from April 1, 2017 to June 14, 2017. For analyzing data, the SPSS 22.0 program was used and the homogeneity test was analyzed with ${\chi}^2$ test, t-test, and Fisher's exact test. Also, independent-test was used. According to the result, all of the experimental groups including the basic nursing performance ability, confidence in performance, learning self-efficacy(t=15.304, p<.001), and practice satisfaction(t=15.304, p<.001) were improved and showed significant differences compared to the control group. As a result, it is predicted that the practice method has a positive effect on participating in self-study and it contributes to active participation by increasing learning motivation of learners. Thus, it is suggested to be applied to various practical training to improve basic nursing skills.
