In order to enhance the effect of Problem-based Learning, the role of scaffold as a learning support strategy is necessary. Collective intelligence provides scaffolding in the sense that it integrates users' knowledge, information, experiences, values, etc. Based on these factors, collective intelligence determines the direction of behavior, revises the direction continuously, and provides problem-solving methods. Teaching and learning situations emphasize learners' initiative, voluntary, and active participation. Thus, this study was conducted to find out if collective intelligence can be an effective and attractive alternative of learning strategy. Specifically, this study purposed to examine how collective intelligence performs the role of scaffold on the Web and what types of scaffolding are provided to learners. According to the results of this study, collective intelligence had a positive effect on learners' learning attitude, confidence, interest, etc. in the affective aspect, but its effect on the cognitive aspect was different according to learners' school year and learning level. Because collective intelligence had a positive effect on learners, we identified scaffolding types explanation, suggestion of direction, illustration and feedback in the cognitive aspect, and positive response and encouragement in the affective aspect.

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 purpose of this study was to determine whether there are differences in the verbal interactions of earth science gifted depending on their communications structures and group status in small group activities. To this end, a small group activity was conducted to measure the density of the earth, and 8 small groups were selected, including 4 co-ownership type and 4 monopolistics type groups with different communication structures. And then, the framework was developed for analyzing verbal interactions to compare the differences in characteristics between small groups. The results are as follows. First, regardless of the communication structures, there were showing a simple pingpong-type communication structures for all small groups. Second, negative interactions such as 'restraint', 'command', 'complaint', and 'lack of confidence' predominantly appeared in all small groups. Third, the students in the status of out-lookers in small groups were mainly verbal interactions, such as instructing the other person, acting against the other person's actions, and expressing dissatisfaction with the attitudes and abilities of members. Therefore, teachers should guide students to use higher-level verbal interactions in their group activities in small group activities, and engage in students communication to prevent negative interactions from occurring. The teachers also need to check the level of achievement for students in the status of out-lookers in advance and guide them to participate more actively in small group activities. This study is meaningful in that it can be sued to design teaching and learning to improve students' problem solving and communication skills.

Purpose: The purpose of this study was to analyze papers on child rearing in Korea and to suggest future research and nursing practice directions for child rearing. Methods: An on-line search via 5 web sites yielded 201 research papers. The analysis of key concepts was based on the attributes of parenting and type of knowledge held by the parents. Results: The research papers found in the search were 27.3% experimental and 72.7% non-experimental. Among the participants, 77.0% of parents raising the child were mothers and the children were mostly young children under the age of one year. Types of knowledge related to child rearing varied widely, but explanatory knowledge (55.2%) was the most common, followed by prescriptive knowledge (30.0%) and descriptive knowledge (14.8%). For attributes of parenting, reaction to parenting (49.9%) followed by parenting behavior/practice (43.1%) was most common. Conclusion: Findings of this study indicate that further research is necessary regarding fathers and surrogate caregivers and on prescriptive knowledge for health promotion of children at different developmental stages. Also the results suggest a need for research toward developing child care policies.

This phenomenological study aims to explore Nursing Students' Experiences who have experienced team-based learning (TBL). The purpose of this study is to contribute to fostering professional nurses required in the clinical field by improving the learning outcomes by applying the TBL classes. The study participants were seven students of the nursing department who took TBL classes in adult nursing classes. The data were collected through participating observations and in-depth interviews, and analyzed using Colaizzi's phenomenological methods. As a result of the study, nine conceptual descriptions and five theme clusters were derived. The major theme clusters for the experiences of students were 'Dedication to best results', 'Self-led learning attitudes are formed', 'Becoming a communal knowledge creator', 'Active class time', and 'Meaningless peer evaluation'. Nine conceptual descriptions were 'Doing one's best to fulfill one's role', 'Preparing for the class with the pre-learning', 'Forming confidence through pre-learning', 'Solving problems through interaction with friends', 'Becoming a mentor to each other', 'Working together to resolve issues', 'Intimacy formed', 'A lively class', and 'Peer evaluation with familiarity'. This study contributes to the improvement of the learning outcomes of the nursing students by enabling learner-centered classes and self-led learning, thereby contributing to fostering the professional nursing manpower required in the clinical field.

This study aims to grasp the general conditions regarding university students in security related majors in Korea. Followings will be covered here: what motivated them to choose those majors, hw much are they git jobs through the education, what is their conscioucness on their majors, jobs, and courses like, and what effects their job preference. And ths study also aims at helping the student with their future plans such as admission to a school of higher grade and choosing their job. For this study, we distributed 340 copies to the students in security related majors at 4 four-year colleges and 1 two-year college, and collected 298 copies by means of quota sampling method. For collected questionnaires, we used individual T-test verification and one-way ANOVA analysis to grasp the situation. Significance stabdard for the test results was set as p<0.05. Followings are the test results. The results on analysis of satisfaction rate on their curriculums, classes, and majors show that students in security-related majors showed different satisfaction rate and different averages according to their sex and the year of the college. In the analysis on the relationship between major education and employment of students in security-related majors, the result of curriculum improvement and scholaril attainments analysis showed statistically significant relation. When students in security-related majors were surveyed on their consciousness of their future plans such as getting jibs, two-year college students had more certificates of qualification for employment than four-year college students.

Ectodermal dysplasia is a genetic birth defect in which at least abnormally develop two structures derived from the ectoderm. It is usually inherited in autosomal dominant or autosomal recessive pattern. Oral manifestations are oligodontia, anodontia, dysmorphic teeth(conical shape), decreased occlusal vertical dimension and alveolar bone. Extraoral signs may include decreased or absent sweat glands, sparse and fine hair, saddle nose, hearing loss and decreased production of body fluids including saliva. Most affected children require extensive dental treatment to restore their appearance and help the development of a positive self image. The patient's overclosed profile was due to a decreased vertical dimension. The use of overdenture is to preserve erupted teeth, to accomodate the newly constructed occlusal plane, to improve retention and stability of denture and to maintain the remaining alveolar bone. The restoration of vertical dimension improved the child's speech, swallowing, and eating. Growth continue until the age of approximately 18. As child grows, replacement dentures will have to be fabricated primarily to accomodate increasing vertical dimension and changing dentition. Implants may be indicated later if the alveolar bone is adequate. Periodic recall visits are advised, to monitor the dentures during periods of growth and development, and eruption of the permanent teeth.

수학적인 사고력과 창의력이 강조되고 있는 요즈음 수학교육에서는, 이산수학적인 영역이 담당해야 할부분이 더욱 많아진 것으로 생각된다. 이에 발맞춰, 최근에 이산수학에 관한 연구가 활발해지고 있다. 그러나, 아직 초등학교에서 적절히 사용할 수 있는 별도의 이산수학 관련 서적이나 연구 문헌이 없어 아동들의 이산수학에 대한 관심과, 수학 성적과 이산수학의 문제 해결력과의 관계에 대하여 조사해 보았다. 이산수학의 문제들을 구성하여 아동들에게 예고 없이 평가하고 문제에 대한 수학적인 태도를 질문을 통하여 알아보고, 수학 실력이 우수한 학생과 그렇지 못한 학생들과의 이산수학 문제 해결력의 관계를 알아보고자 다음과 같은 연구 내용을 설정하였다. 이를 살펴보면 첫째, 초등 수학교육에서 이산수학에 대한 학생들의 반응에 대하여 생각해 본다. 둘째, 수학 성적과 이산수학 문제 해결과의 관계를 생각해 본다. 이상의 연구 문제를 해결하기 위해, 문헌 연구를 통하여 이산수학에 관련된 초등학교 내용을 소개하고, 문항을 구성하였다. 소개된 주제 중에서 4개의 주제(수 세기, 한 붓 그리기, 지도 색칠하기, 최소 거리 ${\cdot}$ 비용 수형도)를 선정하여 10개의 문항을 작성하였다. 조사 연구를 위한 대상은 서운 시내 2개 초등학교 5, 6학년 2개 반을 선정하였다. 각 문항의 정답율은 백분율(%)에 의하여 분석하였는데 그 결과를 살펴보면, 첫째, 수 세기의 정답율은 첫 번째 문항의 정답율이 낮았을 뿐, 다른 문항들의 정답율은 비교적 좋게 나타난 것으로 보아 문제를 이해하기 쉽게 구성하는 것이 중요하다는 것을 알게 되었다. 둘째, 한 붓 그리기와 지도 색칠하기의 문제들의 정답율은 상당히 높게 나타났는데, 그러한 것은 아동들이 직접 다양한 방법으로 시도해 봄으로써 문제를 해결할 수 있었기 때문인 것 같다. 또한 이러한 유형의 문제들은 아래 학년에도 투입해 볼 수 있을 것 같다. 셋째, 최소거리 ${\cdot}$ 비용 수형도의 문제에서는 난이도가 높은 이유도 있지만 문제 이해를 완전히 하지 못해 정답율이 무척 낮게 나온 것으로 생각된다. 넷째, 수학 성적이 높은 학생들이 대체적으로 문제 해결력이 높았던 것으로 나타났으나, 몇몇 학생들은 정반대의 결과가 나와 특이한 시사점을 제공했다. 그러한 이유로는 정형화된 문제들을 선호하고 쉽게 해결하는 아동들과, 그렇지 않은 아동들 사이의 문제 접근 방법의 차이라고 생각된다. 본 연구를 통하여 다음과 같은 제언을 하고자 한다. 첫째, 이산수학에 관련된 많은 문항을 개발하여 아동들에게 확대 투입함으로써 수학 수업의 효과와 문제 해결력을 높일 수 있을 것이라 생각된다. 둘째, 수학 실력이 떨어지는 아동들에게 보다 흥미있는 이산수학적 문제들을 제시함으로써 수학에 대한 자신감과 흥미를 높일 수 있을 것이라 생각된다. 셋째, 초등학교 과정에 알맞은 이산수학의 다른 주제도 학습 지도안과 그와 관련된 문제들을 개발하는 연구가 진행되어야 하겠다.

We incorporated cooperative learning focusing on the 'Crustal Deformation' in five classes of second grade students, at an all-girls' middle school of Gimje city. The groups of cooperative learning were composed of four members of students each, according to the heterogeneous level. We conducted a pretest on the students' preference before incorporating the cooperative learning. After ten weeks of cooperative school work, the students took a post test with the same questions as the pretest. The result of this method greatly impacted the change on the students' scientific preference. It means that the students showed a positive change in their awareness of and participation in science classes, compared to before. However it is difficult to distinguish the differences in their scientific attitude on the recognition about scientists and habits which make them think scientifically. This resulted from the short period of ten weeks which is not sufficient to carry out the study strategy effectively. Surveys of the students on cooperative learning indicates that the middle level students prefer this method unlike the higher or lower level students. we are convinced that they can learn from the students of higher level and are able to help the lower level with the interaction through cooperative learning. According to the result of the survey, the method has some weaknesses; it arouses the high noise levels and consequent disturbance due to verbal interaction and of conflicts due to disagreements when they discuss the process. On the contrary, advantages are developing the students's interest in science class, helping them to learn, creating positive participation in class, and fostering mutual collaboration with other students through cooperative learning.
