In this thesis, a field experience activity support system is designed and implemented for improving social skills of children with developmental disabilities. The proposed system is designed to allow the students to experience various field activities around their local community. The proposed system has the following characteristics. First, it can improve effectiveness of field experience by providing very practical pre-study information to students. Second, the systems provides very practical and real-world problem-solving abilities rather than providing simple experience and superficial information. Third, the system allows students to change the contents according to their local community environments and purpose of use. Fourth, the system can be used as education for living at home as well as field experience study at schools. After applying the proposed system to students with developmental disabilities, the following positive results are obtained. First, the system have good effect on students with severe developmental disabilities when the system is used for prestudy. Specially those students are highly interested and motivated on study subjects. Second, at real field experience study place, students are well adapted and are very interested in their activities. Third, in the light of post-evaluation after field experience, it is reported that lots of study contents remain in their memory.

The purpose of the study was to assess the knowledge of infant development of child care teachers, undergraduate students majoring in child development at universities, and the students at child care training centers. A questionnaire was distributed to 126 in-service and 187 pre-service child care teachers. Data were analyzed by t-test, F-test, Correlation. The results showed that the mean scores of subjects on the Knowledge of Infant Development Inventory (KIDI) were relatively low. Among the 3 groups of subjects, child care teachers had the lowest scores on the KIDI. There were individual differences in the knowledge of infant development by school year, the length of work experience, marital status, age of child, attendance at in-service training events, and kind of license.

The concepts of ratio and proportion do not develop in isolation. Rather, they are part of the individual's multiplicative conceptual field, which includes other concepts such as multiplication, division, and rational numbers. The current study attempted to clarify the beginning of this development process. One fourth student, Kyungsu, was encourage to schematize his trial-and-error-based method, which was effective in solving so-called missing-value tasks. This study describes several advancements Kyungsu made during the teaching experiment and analyzes the challenges Kyungsu faced in attempting to schematize his method. Finally, the mathematical knowledge Kyungsu needed to further develop his ratio and proportion concepts is identified. The findings provide additional support for the view that the development of ratio and proportion concepts is embedded within the development of the multiplicative conceptual field.

사회는 빠르게 변화하고 있으며, 그러한 변화는 새로운 적응을 요구하고 있다. 그래서 오늘날의 사회는 “사고력의 사회”라고 생각하는 지도 모르겠다. 이에 발맞추듯, 교육과정에서도 사고력 개발의 필요성을 역설하고 있지만, 실제 교육현장에서는 어떠한가? 어떻든 이런 저런 이유로 ‘주입식’수업, ‘암기식’수업은 안 된다고 오랜 세월 많은 연구자들이 합창을 해왔다. 그러나 ‘예전대로’, ‘하던대로’의 전통은 별로 바뀌지 않고 계속되고 있는 것 같이 보인다. 따라서, 본고는 아동들이 수학수업에서 사고학습을 어떻게 함으로써, 아동의 능력을 강화하고, 아동의 인지발달을 촉진하며, 개인의 지식 수준을 향상시킬 수 있는 특별한 방법을 찾고자 한다.

최근 들어, 갈수록 다양화 ${\cdot}$ 다기화 되어 가는 사회 상황은 우리로 하여금 끊임없는 선택을 하도록 요구하고 있으며, 그것은 다시 깊고 넓은 생각을 하도록 요구하고 있다. 또한 사회 변화의 가속화와 경쟁의 첨예화는 우리로 하여금 그 선택과 그에 따른 생각을 보다 신중하고 현명하게 하도록 요구하고 있다. 이에 따라, 초등수학교육에서도 사고력 신장을 위한 수업방법의 필요성을 역설하고 있다. 따라서, 본고는 아동들이 수학수업에서 사고력 신장을 위한 수업 방법을 탐색해 봄으로써, 아동의 능력을 강화하고, 아동의 인지발달을 촉진하며, 개인의 지식 수준을 향상시키고자 한다.

Purpose: The purpose of this study was to examine how child development knowledge, child rearing knowledge, and use of healthcare services after discharge affect maternal confidence among mothers of premature infants. Methods: Participants in this study were 55 mothers who were involved in internet communities for mothers with premature infants and 30 mothers who visited hospitals for follow up care after having their babies discharged from Neonatal Intensive Care Units (NICU) in South Korea. Results: Presence of operation history, child development and rearing knowledge, and use of healthcare service explained 12.2% of maternal confidence. Presence of operation history (${\beta}=.32$, p<.05) and child development knowledge (${\beta}=.52$, p<.05) were significant predictors for maternal confidence. Conclusion: The results of this study suggest that mothers with premature infants need further education especially on motor development, developmental knowledge, and knowledge related to operations for mothers whose child had surgery in the NICU. Also information about services provided from community health services for premature infants need to be advertised and distributed.

In this study on the development of children's understanding of varieties of expertise, forty-seven 3-, 4- and 5-year old children were asked to differentiate expertise in the minds of adults, using twenty-four questions consisting of 3 levels of inferences, False belief tasks were also provided to discover correlations with knowledge of various pockets of expertise, Results revealed that 4- and 5-year olds made more correct attributions than 3-year olds. Children also inferred attributions properly on familiar experts, understanding of stereotypical roles, normal functioning, and underlying principles, in that order. Children's concepts of varieties of expertise were correlated with their understanding of false beliefs.

의학의 발달과 산업화로 인한 생활환경의 향상은 인류에게 질병으로 인한 고통이나 사망의 위험에서 벗어나게 해 주었다. 그러나 최근 우리사회에서 일어나고 있는 대형 안전사고로 인한 사망이나 부상피해는 갈수록 높아지고 있다. 이는 사회 전반에 퍼져있는 안전의식의 결여가 낳은 결과로, 사고를 사전에 예방하고, 사고로 인한 인명피해를 줄이기 위해서 모든 국민은 안전교육의 중요성을 인지하고, 교육의 활성화를 위해 노력해야 한다. 특히, 감수성이 예민하고 지식이나 가치관, 태도의 형성과정에 있는 어린이들에게 안전의식을 체계적으로 형성하고 관련지식을 갖도록 하는 것은 중요하다. 일선 학교 교사들도 안전교육의 필요성은 느끼지만, 교육적으로 활용할 수 있는 자료는 많이 부족한 실정이다. 이에 본 연구에서는 초등학생을 위한 안전교육 코스웨어를 연구하여 이를 아동들이 언제 어디서나 웹을 통하여 학습할 수 있는 장을 마련함으로써 아동들에게 안전에 대한 경각심과 안전의식을 심어주는데 목적이 있다.

This study analyzed physical knowledge displayed in the utterances of 10 Korean children 23 - 76 months of age. Utterances were blocked into four-month time periods, except the first two months and classified into 5 categories including properties of physical objects and materials, friction, buoyancy, gravity, and the motion of physical objects. All five types of physical expressions were found in the data of the earliest period the percent age of the properties and motion was higher than the percent of friction, buoyancy, and gravity. Data suggested two transitional points of change in physical knowledge : 2-year-old's descriptions were based only on perceptually salient physical features 3- to 4-year-olds described only end-state results while children older than 4 included systematic causality.

The purpose of this study was to explore the characteristics of children's interactive learning focusing on the Vygotsky's ZPD (the zone of proximal development) in a natural history museum as a representative free-choice learning context. We focused on the understanding of peer dyadic discourses and data were collected from 13 peer groups of children (3rd and 4th graders) who were videotaped all conversations occurred as they visited around the exhibits with no predetermined path. The transcribed data were analyzed by the developmental level of ZPD system and the discourse within an ADL (an actual developmental level) was overwhelmingly common in the conversations between child-child dyads. The representative discourse by discourse types were parsed according to three constructs of ZPD. Children formed the intersubjectivity through semiotic mediation such as conversations and exhibits and ended up with the similar situation definition. In conclusion, the details of discourses of the most impressive dyad were looked into focusing on the scientific concept. The study implies that a natural history museum becomes a meaningful resource to offer a deeper understanding of the nature of children's learning as an informal learning setting.
