We have analyzed the science-gifted educational program (year 2002) at the Seoul National University in terms of its educational objectives, scientific models, and cognitive processes in scientific inquiry in order to provide insights into developing and improving science-gifted educational program. We assumed the following items as important factors for teaching scientifically gifted students: higher-order thinking skills involving synthesis domain in the educational objectives, highly abstract nature and complexity in the scientific models, cognitive processes of planning experiments in the cognitive processes in scientific inquiry. According to the analyzed results, the program has the following characteristics: (1) the rates of both higher and lower-order thinking skill domain in the educational objectives are similarly high, but the rate of synthesis domain is relatively low; (2) in the case of the scientific models, the rate of the multiple concepts and/or processes model is relatively low, while the level of the abstractness is relatively on average (3) cognitive processes of authentic scientific inquiry is not thoroughly reflected in the scientific inquiry activities, and very few cognitive processes of planning experiments factor is reflected. Therefore, we conclude in the synthesis domain in the educational objectives, multiple concepts and/or processes model, and cognitive processes of planning experiments should be especially reflected more on the science-gifted educational program in order to serve the needs of scientifically gifted students.

Flapper Valve of Korean Utility Helicopter(KUH-1) is an essential equipment in Environmental Control System(ECS) for pilot to perform flight mission. It provides pilots and crews with heating, ventilating and air conditioning. It has function of maintaining room temperature to sustain operational capability for pilot and crew. This paper summarizes pilot comments in flight test which are classified by cause of occurrence and the troubleshooting process about each comment. It also describes design improvements which was derived from troubleshooting and suggests verification results of flight test at low temperature.

The purpose of this study is to analyze the teaching and learning strategies included in the inquiry tasks of elementary moral textbooks with multiple intelligences (M.I), and to propose educational information services of teacher librarians. It was found that the tasks were mainly designed by the linguistic intelligence, logical & mathematical intelligence and spatial intelligence. In terms of the information literacy process, linguistic intelligence and spatial intelligence are mainly applied to the analysis-understanding stage. Logical & mathematical intelligence is applied to the stage of comprehensive-application and linguistic intelligence is applied to expression-delivery step. In order to cultivate the insufficient M.I in inquiry activities, teacher librarians should improve room and teaching materials of their school library and provide workbooks using the graphic organizer after analyzing the linkage of the inquiry tasks between the subjects.

고등학교 수학과 교육과정에서의 ‘확률과 통계'단원은 실제로 자료의 수집과 요약을 통하여 자료 분석방법을 배우고 사회와 자연현상을 인식하고 추론하는 능력을 기르는데 목표를 두고 있다. 추상적인 수학내용을 직접 시도하거나 학생들이 실제적인 자료를 수집하고 직접 자료를 해석하고 추론해 보는 경험과정은 수학실험과 시뮬레이션이라는 컴퓨터 학습을 통해 가능하고 개념학습의 전 단계에서 보다 구성적이고 탐구적인 활동을 강화할 수 있다. 본 논문에서는 ‘확률과 통계'의 교수-학습과정에서 수학적 시뮬레이션을 활용한 웹 기반 학습모형을 제시하여 학습자들에게 수학적 내용과 관련된 구체적 매체를 조작하는 컴퓨터 실험 활동을 통하여 수학에서의 원리발견과 통계적 추론을 경험하고 유도할 수 있는 탐구적 학습 환경을 조성해 보고자 한다.

In this study, the test that were used in entrance examination for chemistry class in a Science-Gifted Education Center for middle school students were analyzed by using criteria for identification and measurement of scientific giftedness and a classical test theory. The result of analysis exhibited that most of problems measured more than two elements of scientific giftedness and required applications of scientific knowledge of middle school level to solve problems. In the analysis of sub-elements of scientific giftedness, originality, fluency in creativity and finding problems/formulating hypothesis, planning inquiry, interpreting data in science process skills were dominant while drawing conclusion and generalization processes were lacking. In correlation analysis between total score and each type of problems, total score was most influenced by the problems measuring science inquiry linked with scientific knowledge. Item difficulty is moderately high and item discrimination is moderate.

The purpose of this study was to examine the effect of SSC(Small-Scale Chemistry) lab program applying to scientifically gifted students' classes. The participants were 15 the middle school scientifically gifted students selected and enrolled in science-gifted education center of university. SSC lab program was applied for 3 month with 5 topics. The research design was one group pretest-posttest design, the data were analyzed using the PASW 18 statistics program. The results of this study were as follows: First, the scientific attitude of scientifically gifted students was improved significantly(p<.01) after applying SSC lab program. Especially, there were significant difference between pre-test and post-test in the scores of cooperativity, spontaneity, perseverance, which were the sub-region of scientific attitude. Second, the creative personality characteristics of scientifically gifted students showed statistically significant improvements(p<.01) after applying SSC lab program. Especially, there was significant difference between pre-test and post-test in the scores of adhesion, which was a sub-region of the creative personality characteristics. Third, there were no significant differences in the science inquiry skills between before and after applying the SSC lab program in the scientifically gifted students' classes(p>.05). The results suggest that SSC Lab program is an effective program in scientifically gifted students' classes.

We consider a Direct Input Output Manufacturing System(DIOMS) which has a munber of machine centers placed along a built-in Automated Storage/Retrieval System(AS/RS). The Storage/Retrieval (S/R) machine handles parts placed on pallets for the operational aspect of DIOMS and determines the optimal operating policy by combining computer simulation and genetic algorithm. The operational problem includes: input sequencing control, dispatching rule of the S/R machine, machine center-based part type selection rule, and storage assignment policy. For each operating policy, several different policies are considered based on the known research results. In this paper, using the computer simulation and genetic algorithm we suggest a method which gives the optimal configuration of operating policies within reasonable computation time.

This study mainly intended to investigate the relation between scientific inquiry and several entrance exam results of the gifted in earth science gifted program. The scientific inquiry was tested with their experiment designs. Entrance exams included achievement scores, creativity scores, problem solving, and oral test of high ability students. Student entrance scores were used to judge the level of students' competency in science. Recently students' ability of 'doing science' as measured by their designing experiments has been highly appreciated as a criteria of scientifically gifted students. One of the well known tests was Diet Cola Test developed by Fowler(1990). We used it as a test to figure out students' experiment design ability. We selected 22 gifted students in earth science. We compared their entrance test scores and Diet Cola Test results. Based on the comparison results we proposed several guideline of science education program for high ability students.

학교 현장에서의 컴퓨터 교육은 여전히 시범실습위주로 이루어지고 있으며. 초등학교 컴퓨터 교육에서 많은 비중을 차지하는 소프트웨어 교육은 더욱 그러하다. 소프트웨어는 끊임없이 개발되거나 업그레이드 되고 있어 가르쳐야 할 내용이 많아져 새로운 학습방법이 필요하다. 즉 문제사태에서 필요한 기능을 찾아 스스로 문제를 해결하고 다른 응용소프트웨어에 전이 및 파지할 수 있는 능력을 길러주는 학습방법이 필요하다. 그 방법 중의 하나가 구성주의 학습 원리에 부합한 문제중심학습이며 학습의 효과를 높이기 위해서 온라인과 오프라인학습의 장점을 혼합한 B-러닝 방법이 필요하다. 따라서 본 연구는 응용소프트웨어의 적응력을 향상시키기 위해 한글 워드프로세서 학습내용을 학습자의 수준에 맞게 문제중심으로 재구성하고 온라인 학습을 위해 학급커뮤니티를 설계 및 구현하였다. 그리고 문제중심의 B-러닝에 적합한 학습모형을 설계하여 제시하였다. 문제중심의 B-러닝은 구성주의 학습 원리에 적합한 실생활의 문제를 학습내용으로 하고 면대면 교실수업의 장점과 온라인 학습의 장점을 혼합하여 자기주도적으로 탐구학습을 하는 것이므로 응용소프트웨어의 적응력은 향상될 것으로 기대한다.

사회과에서는 학생들이 주제를 정해 스스로 계획을 세워 조사하고, 사회를 탐구해 가며 조사 보고서를 정리해가는 능력을 중요시 여겨왔다. 따라서 교육 현장에서 가장 많이 사용되는 사회과 수행평가 방법도 조사 보고서 방법이다. 하지만 대부분의 학습자들은 '보고서를 작성해오라'는 지시를 받고 뚜렷한 목표나 체계적인 형식 없이 보고서를 작성하고, 교사에게 제출한 후 학기말 평가 결과만을 일방향적으로 통보 받아왔다. 이에 본 연구는 정적인 텍스트 위주의 보고서 형식에서 벗어나 웹에서 효율적이고 평가의 질을 높일 수 있는 웹 기반 수행평가 시스템을 설계하였다.
