purpose of this study is to investigate the relationship between high school students' Problem Finding Ability (PFA) and chemistry problem solving ability. To achieve this purpose, the interrelationship between the results of PFA in ill-structured scientific problem situation and the scores of sham examination in chemistry I of College Scholastic Ability Test (CSAT) was analyzed. The results of this study turned out to be as follows: There was correlation (r=.346) between the score of PFA test and that of sham examination in chemistry I of the CSAT. And a little correlation (r=.390) between PFA and students application ability which is one of the sub factors in sham examination of the CSAT. Especially, in the high achievers group there was high correlation (r=.446) between students fluency which is one of the sub factors in PFA, and application ability. This implies that the application ability of high achievers has something to do with their PFA for a variety of problems. As for the PFA between high achievers and low achievers, there was no significant difference (t=.830, p=.411).

Spatial ability has been valued as one component of intelligence and as an talented domain. The researchers agree that spatial ability is associated with the achievements in science, technology, engineering, and mathematics (STEM) disciplines and important in STEM education. The purpose of this study is to assess Korean middle school students' spatial ability and compare Gifted Students and General Students' spatial ability. For this purpose, 'The Revised PSVT:R' was translated into Korean and administered 509 Korean middle school students, and also internal consistency reliability evidence and construct validity evidence of 'The Revised PSVT:R' were examined. This study explored the spatial ability of Korean middle school students (graded 7 through 9), and investigated association between spatial ability and students' mathematics achievement, the students' spatial ability according to their gender and grade level. As a result, this study shows that gifted students were better than general students in spatial ability. And there were significant correlations between spatial ability and mathematics, science, Korean language achievement. According to these results, spatial ability should be included as one of the important components in identifying students for gifted education programs.

The purpose of this study was to provide instructional suggestions by investigating the spatial sense and spatial reasoning ability of 6th grade students. The questionnaire consisted of 20 questions, 10 for spatial visualization and 10 for spatial orientation. The number of subjects for the survey was 145. The processes through which the students solved the problems were the basis for the assessment of their spatial reasoning. The result of the survey is as follows: First, students performed better in spatial visualization than in spatial orientation. With regard to spatial visualization, they were better in transformation than in rotation. With regard to spatial orientation, students performed better in orientation sense and structure cognitive ability than in situational sense. Second, the students that weren't excellent in spatial visualization tended to answer the familiar figures without using mental images. The students who lacked spatial orientation experienced difficulties finding figures observed from the sides. Third, students had high frequency rate on the cognition and use of transformation, the development and application of visualization methods and the use of analysis and synthesis. However they had a lower rate on a systematic approach and deductive reasoning. Further detailed investigation into how students use spatial reasoning, and apply it to actual teaching practice as a device for advancing their geometric thinking is necessary.

The purpose of this study is to survey the occupational therapists's vocational core competency. Study subjects were 138 occupational therapists and 95 students majored occupational therapy and they participated in the survey about the vocational core ability to confirm the factors about the vocational core ability. As the results of these, both occupational therapists and university students majored occupational therapy felt the need for vocational ability and communication skills, interpersonal relationship skills, and problem-solving skills were found to be important, and that they also possessed them. However, only in the group of students majored occupational therapy showed that technical skills were important, but they did not possess the most. Accordingly, it is necessary to consider a curriculum that can collect knowledge and information on various skills necessary for actual vocational performance as the occupational therapist.

정보화시대의 도래와 함께 급변하는 정보의 홍수 속에서 학생들이 학교에서 학습해야 할 지식의 양은 방대해진 반면에 미래의 변화하는 상황에 유연하게 대처할 수 있는 다양한 능력을 지닌 인재들에 대한 수요는 더욱 높아지고 있다. 이에 따라 미래의 사회가 필요로 하는 인간상을 구현하기 위해 많은 양의 지식을 가르치는 암기와 훈련 위주의 전통적 교수-학습방법을 탈피하고 학습에 필요한 핵심적 요소를 체계적으로 구조화하여 학습자 스스로 사고하여 문제를 해결하는 능력과 창의적 사고를 배양시키는 교수-학습방법의 필요성이 부각되고 있다.(중략)

본 논문은 다양한 파괴역학 해석방법을 이용하여 원주방향 관통균열이 존재하는 탄소강 및 스레인레스강 배관의 하중 지지능력을 예측하기 위한 것이다. 이를 위해 실제적인 기본모델과 배관 및 균열의 형상, 재료물성치를 변화시킨 가상적인 특정모델을 대상으로 순수 굽힘하중 작용조건에서의 공학적 해석 및 유한요소해석을 수행하였으며, 타당성 검토를 위해 문헌에 제시된 실험결과와 비교하였다. 비교결과, 예측한 하중 지지능력은 각 평가방법 뿐만 아니라 배관 및 균열의 형상, 재료특성 등에 따라서도 차이를 보였으나, 전반적으로는 실험결과에 비해 보수적인 결과를 제시하는 것으로 나타났다.
