최근 모바일 기기의 활성화에 따라 M-learning (Mobile learning)이 활성화되고 있다. M-learning을 기반으로 한 코스웨어나 모듈 설계 시 학습자의 적극적 참여와 의미 있는 상호작용의 기회 제공과 실제적 환경에서의 교육활동을 지원하는 것에 초점을 맞추어야 한다. 근접발달영역이론 (Zone of Proximal Development : ZPD)이란 독자적으로 문제를 해결함으로써 결정되는 실제적 발달수준과 성인의 안내나 보다 능력 있는 또래들과 협동하여 문제를 해결함으로써 결정되는 잠재적 발달수준간의 거리이다. 한편, 스캐폴딩은 학습자의 근접발달영역을 변화시키며, 학습자가 스스로 학습할 수 있도록 도와주는 구체적인 방식이라 할 수 있다. 또한 스캐폴딩 (Scaffolding)은 학습자가 구조를 조직하고 새로운 지식을 구성하도록 교수자 또는 촉진자가 도와주면서 교수자와 학습자간에 상호작용하는 과정이다. 본 연구에서는 근접발달영역이론을 이용하여 모바일로 교사가 학습자에게 스캐폴딩을 제공하는 수업모형을 제안한다. 본 모형의 특징은 다음과 같다. 첫째, 문제해결을 위한 스캐폴딩만이 아니라 문제 해결 후 격려 스캐폴딩을 제공하여 학습력 강화가 이뤄지도록 하였다. 둘째, 교사와 학습자 사이에 다양한 스캐폴딩을 제공하여 상호작용을 강화하였다. 셋째, 자신에게 맞는 개별학습, 반복 학습이 가능하고 자기 주도적 학습이 강화되도록 하였다.

A study was designed to evaluate the level of moral development in 450 pre-dental professionals of 2 educational institution in Jeollabukdo, Ik san city. Data were collected through self-reported questionnaires from October 2010. The Korean version of the DIT(Defining Issues Test) was adopted to evaluate level of moral development with the score of P(%) and stage. The data were analyzed by descriptive statistics, t-test, one-way ANOVA and Pearson's correlation coefficient. The mean scores of P(%) was 43.10 in dental students and 41.21 in dental hygiene students(p=0.190). The score of stage 5A was highest which was followed by S3, S4, S6, S5B, S2. The score of stage 5B and 6 revealed sigificant difference by groups. The score of stage 6 revealed significant difference by sex in dental students(p=0.003). In dental hygiene students, it's significant difference by religion(S5B, p=0.044), birth order(S2, p=0.027) and growth area(S4, p=0.015). As for the correlations between moral development and the score of the stage, the score of P(%) was negatively correlated with the scores of stage 2, 3, 4 and 5B. On the other hand, the score of P(%) was positively correlated with the scores of stage 5A and 6. In conclusion, for enhancing dental students' moral development it is necessary a systemic ethics education and program development in curriculum.

The purpose of the study was to analyze and interpret parent-child dyadic discourses in depth with emphases on the ZPD system in a museum, an informal learning setting. Second graders and their parents from Seoul and its environs were voluntarily participated in the study. Data were collected from the museum documents, the photos of exhibits, and the video recordings of dyadic discourses at and between exhibits. The documents and the photos were analyzed to investigate what the topics, medium and goals of the exhibits were. The video recordings were all transcribed and analyzed to understand what and how they talked to each other through the lens of the ZPD system; situation definition, intersubjectivity, and semiotic mediation, The results of the study consisted of two parts. First, it showed that parent-child dyadic discourses were categorized in four: (1) within the actual developmental level; (2) in the zone of proximal development; (3) toward the potential developmental level; and (4) out of developmental level. The most common categories were the dyadic discourses within the actual developmental level and in the zone of proxima I development. Second, the representative cases in each categories were described and interpreted to understand the nature of parent-child dyadic discourses. It can be concluded that we gained some important understandings of an intrinsic attribute of parent-child discourses in a museum, an informal learning setting. Based on the results of the study, it can be suggested that museums make efforts to cultivate the affordance of exhibit environment to promote visitor's learning.

This study analyzes the effect of poverty on child development outcomes including academic achievement, self-esteem, depression/anxiety, attention problems, aggression, and delinquency. The poverty experiences among elementary school children are longitudinally observed during 3 years between the 4th grade and the 6th grade. When development outcomes are compared among persistently poor children, transitory poor children, and non-poor children, academic achievement is found to be significantly different. The analyses of the relationships between the poverty status and developmental trajectories show that academic achievement among non-poor children has improved over time, while the level of poor children's achievement has decreased. The result also shows that problematic behaviors such as attention problems, aggression, delinquency has improved over time among all the children. Yet, the gap between poor and non-poor children has not decreased. The multivariate analyses indicate that the effect of poverty remains statistically significant only for academic achievement after children's individual and familial characteristics are controlled. Past experiences of poverty in addition to the current poverty affect academic achievement and persistent poverty has a stronger effect than transitory poverty on academic achievement, although the findings are not consistent across all the estimated models.

In this study, 284 families of people with developmental disabilities responded to a survey about the importance of family support services and their recognition level of satisfaction. First, there was a statistically significant difference in the level of importance-satisfaction recognition of family support services for the people with developmental disabilities. Second, the recognition level of the importance of family support services of the people with developmental disabilities was in the order of support for parenting, support for physical and material wellbeing, support for family interaction. Third, satisfaction of family support services of the people with developmental disabilities was in the order of support for parenting activities, support for family interaction, support for emotional wellbeing. Fourth, we proposed the maintenance of the status quo, improvement efforts, and the need for mid-and long-term strategy by analyzing the characteristics of the importance-satisfaction quadrant. The results of this study are expected to be useful as basic data for improvement of family support services for the people with developmental disabilities.

This study investigated relationships among infant development, teacher's sensitivity, home literacy environment, and infant-teacher interaction in the child care setting. Verbal and behavioral interactions between 30 2-year-old infant-teacher pairs were video-recorded during free play activities; teachers' sensitivity was observed by trained observers; infant development was assessed by teachers; data on the early home literacy environment were gathered through maternal self-reported questionnaires. Data were analyzed by descriptive statistics, t-tests, and correlation analyses. Results indicated that boys showed more naming; girls showed more physical contact with teachers. Infants high in overall developmental level showed more behavioral interaction with teachers. Teacher's sensitivity correlated positively with behavioral imitating and negatively with questioning and nodding. Verbal interaction in the home correlated positively with nodding.

The study purposed to assess how the career development before and after entering college was related to youth's college life satisfaction, and examined the effect of social relationships with parents, peers, and teachers on the association between youth's career development and their satisfaction with college lives. For this purpose, the study utilized the data of Korean Children and Youth Panel Survey (KCYPS) conducted by the National Youth Policy Institute since 2010. The study found that there was a positive correlation between career development and college life satisfaction. In addition, supportive relationships with parents and peers had significant effects on the level of career identity during high school and later satisfaction with college life. It was also found that youth who had a positive relationship with teachers in high school had a high level of career decision after entering college. The results of this study suggested the necessity of individualized career education appropriate for youth's career development levels. In addition, convergent approaches to build, maintain and develop positive social relationships could have a lasting and positive impact on youth's career development.
