The purpose of this study was to develop a teaching strategy focused on problem solving process and explore its effects on science creative problem solving ability, science process skills, science academic achievements and scientific attitudes of students after applying it. Teaching strategy focused on problem solving process employed brainstorming and PMI thinking strategies. The participants were the third grade students of both an experimental class(26 students) and a comparative class(25 students) at the S elementary school located in Goyang-City, Kyonggi Province. The developed strategy was applied to the experimental class for 9 periods of 'Separation of mixture' unit. The results of the tests on the science creative problem solving ability, the science process skills, scientific achievement and scientific attitude were statistically higher in the experimental class.

To analyze the relationships between self-control, thinking quality and mathematical academic achievement, 197 senior school students were asked to complete questionnaires called "self-control ability on mathematics for middle school students" and "thinking quality for senior school students." The results were as follows: (1) There was strongly positive relevance between self-control ability, thinking quality and mathematical academic achievement. (2) A model was presented in which self-control ability had a direct impact on mathematical academic achievement, meanwhile had indirectly influenced mathematical academic achievement by thinking quality which acted as the intermediate variable. Thinking quality had a direct impact on mathematical academic achievement, too. (3) There's no significant difference between the two groups of boys and girls on the structural weights.

It is important to keep learners' feeling positive during learning to enhance learning performance. According to flow theory,challenge-skill balance is a precondition for flow experience: Learners feel anxiety when the challenge of learning is higher than their ability, feel boredom when the challenge of learning is lower than learners' ability, and engage in flow status when the challenge of learning matches the learners' ability. However, the current empirical study reveals that emotions related to enjoyment may appear when the learners' skill is equal to or higher than the learning challenge. Nevertheless, boredom emotion may appear when learners perceive the courses are difficult but unimportant. These empirical survey results revealed the necessary of rethinking the appearance of boredom and enjoyment emotions in computer education.

With the recent revised curriculum, the importance of exploring children's play through new teaching media is increasing in kindergarten. In this study, it is to use the robot 'Bee-bot' for early children to uncover the changes that children have through free exploration and play. As a result of comparing the change of scientific problem-solving ability of 3, 4, and 5-year-olds, there were significant changes in all three sub-elements. We propose to us scientific problem-solving ability test tools, propose and apply ideas for problem-solving, conclusion on problem-solving Building. Through this, it was found that unplugged play using 'Bee-bot' is meaningful as a play environment and as a teaching medium for children aged 3, 4 and 5 years old.

Purpose: This study was conducted to examine the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, clinical performance ability, and problem solving process in new nurses. Methods: An equivalent control group pre-post test experimental design was used. Fifty new nurses were recruited, 26 nurses for the experimental group and 24 nurses for the control group. The simulation-based cardio-pulmonary emergency care education included lecture, skill training, team-based practice, and debriefing, and it was implemented with the experimental group for a week in May, 2009. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability and t-test with the SPSS program. Results: The experimental group who had the simulation-based education showed significantly higher know-ledge (t=5.76, p<.001) and clinical performance ability (t=5.86, p<.001) for cardio-pulmonary emergency care compared with the control group who had traditional education but problem solving process was not included (t=1.11, p=.138). Conclusion: The results indicate that a simulation-based education is an effective teaching method to improve knowledge and clinical performance ability in new nurses learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team discussion on cognitive outcome of clinical nurses such as problem solving skills.

The study was to investigate an effect of students' learning for enhancing spatial ability, using a geometric manipulative recently designed. A mixed methodology was chosen to achieve the purpose of the study. To find students' achievement, 152 of the 8th graders in Kyunggi Do participated in data collection. At the same time. students' performance of the class was videotaped and analyzed to see students' responses, The results showed that the effect of using the manipulative was statistically significant at level, p<.05 to enhance the spatial ability. Specifically, in comparison of each component. spatial orientation was more effective than spatial visualization. In the spatial orientation, the part of field was more effective than the reorganized whole. It showed that students were given more opportunities to find mathematical properties and relations between 2nd and 3rd-dimensional figures through their intuitive observation, and also the manipulative helped the students find the property of the part of field because it gave an easy way to manipulate the property of the find parts of whole which was composed of the frame of the solid figures without surfaces. In using the manipulative, students were very flexible in finding the number of plane figures, but the relations between the 2nd and 3rd dimensional figures need to be clearly guided in consideration of the characteristics of the manipulative, based on the definitions of geometric properties(cf. points can make lines, not surfaces directly).

This article starts with a review of the organization characteristics and corporate education training program, especially in relation to the cyber education. In particular, we empirically analyzed the factors affecting the characteristics of education program (e.g., relatedness of the program contents, method of education and instructor's ability) and the organization characters (e.g., support of manager and coworker, education culture). Hence the main purpose of this article is to suggest an empirical model explaining how these factors affect the transfer of training and enterprise revitalization. Furthermore, we suggested an expanded model about cyber education training program, transfer of training, and corporate's facilitation. We founded that the contents and method of education significantly affect the transfer of training, while instructor's ability does not significantly affect. Supports from manager and coworkers, education culture, and transfer of training also affect the enteprize revitalization.

이 논문의 연구가설은 스마트기기 활용 교육이 장애인들의 교육 및 학습효과로 스마트기기에 대한 사용능력과 활용 정도의 수준을 높여줄 수 있을 것이라는 것이다. 한국정보화진흥원의 '2012년 정보격차 실태조사 원자료' 중 장애인 데이터를 사용하고, 표본선택편의문제 해결을 위해 Heckman의 2단계 추정법을 활용하였다. 실증 분석결과, 스마트기기 활용 교육을 받은 장애인일 경우 종합적인 스마트기기 사용능력과 활용도 수준이 각각 더 높다는 가설이 채택되었다. 스마트기기 사용능력 및 활용도 측면에서는 스마트기기 활용 교육과 높은 학력 가구소득, 전문사무직, 젊은 연령층 등이 긍정적인 유의미한 영향을 미쳤고, 특히 지체장애에 비해서 시각장애일 경우 스마트기기 사용능력 및 활용도 수준이 낮아지는 것으로 나타났다. 이는 시각장애의 경우 특수 보조기기 및 어플리케이션 없이는 생활이 거의 불가능하므로 지체장애의 경우 두 팔 또는 두 손 전체에 이상이 있는 중증장애가 아닌 한 스마트기기 활용 교육을 통해 스마트기기 사용능력 및 활용도 수준이 높아짐을 알 수 있었다. 본 연구결과는 장애인의 스마트기기 활용도를 높이기 위한 공공 정책 또는 민간 협력의 교육프로그램 진행이 그 목적을 달성하면서 교육의 긍정적인 효과를 보여주면서, 한편 장애유형에 따라 보다 정교한 교육내용과 방법이 필요하다는 것을 보여준다.
