This paper describes about the development of the 3 Dimensional interactive physics experiment system using virtual reality technologies. Until now, most of the computer aided education systems have adopted one-sided learning way which only shows or tells. It excludes students during learning processes. To solve the problems of the one-sided learning way and to improve the educational productivity, the 3 Dimensional interactive physics experiment system is developed. The 3 Dimensional interactive physics experiment system introduced in this paper provides a new learning motivation for students and improves their educational effects through the 3 Dimensional graphics, realtime action, and realistic interactive experiment.

The primary purpose of the constructivist teaching experiment is to experience and construct models of students' mathematical teaming and reasoning. The constraints the teacher experience in teaching experiment constitute a basis for understanding students' mathematics. The constructivist teaching experiment that includes a dynamic interaction process between teacher and students and between students and students, is the most hopeful research method in mathematics education. In this paper, I introduced the constructivist teaching experiment and showed several examples of applications that were used in the previous research.

본 연구에서는 사고실험을 이용한 개념변화 수업모델에 따라 면담을 통해 학생의 실제 사고과정을 밝힘으로서, 개념변화과정에서의 주요 특징들을 알아낼 수 있었다. 이미 언급한 바와 같이 갈등인식이 원래의 의도와는 달리 쉽지 않다는 것을 알 수 있었고, 나아가 갈등을 인식하지 않은 것으로 나타났음에도 불구하고 새로운 설명이론의 제시만으로 개념변화가 된 경우가 많아 이에 대한 앞으로의 연구가 흥미로울 것으로 생각된다. 또한, 일단 개념이 변화된 경우에는 비록 이론과 실제 현상과의 불일치를 설명하기 어려워했지만, 간단한 시범과 지도로 쉽게 해결될 수 있었다.

Purpose: The purpose of this study was to examine the effects of a care promotion program based on nursing students' self-understanding. Methods: A quasi-experimental approach using a randomized clinical trial pre- and posttest design was used. Participants were assigned to an experiment group (n=29) or control group (n=30). Data were collected from June 23 to September 8, 2017. The experiment group participated in a care promotion program based on self-understanding for 24 hours through eight sessions covering eight different topics. The data were analyzed using t-test and repeated-measures ANOVA using SPSS/WIN 21.0. Results: Compared to the control group, the experiment group reported significant positive changes for college life adjustment (F=28.74, p<.001), emotional intelligence (F=15.66, p<.001), and interpersonal caring behavior (F=9.37, p=.003). Conclusion: Findings from this study indicate that care promotion based on a self-understanding improvement program with the application of group enneagram education is a useful intervention strategy to promote the care promotion program based on nursing students' self-understanding. Care promotion based on self-understanding will be utilized as an intervention program to form positive values of care and interpersonal relationship through care awareness, self-change, understanding of others and care experience in the group.

In this study the effects of science teaming with the level of inquiry requirement in elementary school science experiment instruction were investigated on cognitive domain. We assigned seventy-three students of the fifth grade into two groups according to the levels of inquiry requirement. After each instruction was implemented, the characteristics of the students' tearning science on cognitive domain were compared and analyzed with the levels of them. The higher level (HL) inquiry-required instruction was more effective in increasing and maintaining the memory on the science teaming than the lower level (LL). Especially, in the aspects of the experimental methods and taking cares which the students engage and perform actively rather than do passively, the memory scores of HL group were higher than those of LL. In addition, the memory scores and the degree of maintenance were higher among students who perceived the instruction as easy and interesting. In conclusion, the HL of instruction could stimulate the students to challenge the problems, thereby make them construct meaning actively and improve the amount and degree of maintenance of memory on science teaming.

Parents' influence on children's development is generally considered essential. This paper attempts to explore the role of AR in preschool education from the perspective of parents, aiming to help parents better understand the impact of children's use of augmented reality in preschool education. The subjects were parents of children in the preschool age range (3-6 years old), and the experimental equipment was AR cognitive cards. In order to extract parents' views on AR, five parents were invited to conduct an experiment with their children using AR cognition cards, and then an open interview survey was conducted. In the second experiment, the answers obtained from the first experiment were sorted out and formed a questionnaire to conduct a closed-book survey. It shows that parents are satisfied with the characteristics of AR to assist their children's learning. At the same time, parents also value technology, usage management and playing environment. AR can stimulate children's learning initiative. Children like to use AR, AR is suitable for learning, make parents satisfied. But even if AR is suitable for learning, parents will control the time their children use it.

The purpose of this study is to develop cyber class contents on website and to verify the effectiveness of the program to reinforce a career education. The participants of the experiment in this study are from Namseoul University who took the cyber class 'Self management and creation of vision.' of the second semester in 2015. They took the class fifty-sixty minutes a week. The control group also includes the students who took the classes 'Theory and practice of school violence prevention' and 'Youth Education theory.' To verify the effectiveness of career education, the data processing in performing this study utilized t-test for homogeneity with the effective variable of career identity and career decision and the result was proved by using paired t-test. The result suggests that the experiment group significantly shows improvement compared with the control group in the view of career identity and career decision level. Therefore we recognize that the web based cyber course has its effect on content development and career education and we anticipate the continuous development and activation of effective cyber education on website for university students in future.

The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.
