This study was attempted to investigate the relationship between the academic achievement and the internal and external motivation of academic achievement. Here, the internal motivation of academic achievement refers to the case that a student feels the necessity of study and h satisfaction, expects rewards, or has interest in his study; external motivation of academic achievement means that a student has outward motivation such as other's recognition, rewards, or compulsion. As the result of this study, there showed significant difference in the academic achievement in proportion as the level of internal and external academic achievement motivation (P<.001). the students with the higher internal motivation and the lower external motivation turned out to have the highest effect of academic achievement; on the other hand, the students with the lower internal motivation and the higher external motivation showed the least academic achievement. There was 11.60 points-difference on the average between those two groups in terms of grade. The academic achievement and the internal motivation shows significant correlation(r=.25, P<.001) while academic achievement and the external motivation presents negative tendency (r=-.10). Through the results of regression analysis, the estimation of the academic achievement by the two variables to academic achievement motivation was 6.22%(P=.0001)

Drawing on social and cultural capital theory, the study investigates the influences of social capital and cultural capital on the academic achievement of children in out-of-home care. We collected data from 494 children living in out-of-home services, including institutional care facilities, foster care homes, and group homes. To analyze the collected data, a multiple regression analysis method was used. In addition, the IV (instrumental-variables) estimation was utilized to rule out the possibility of reverse causality. The level of children's social capital was measured through children's relationships with parents and friends, parental monitoring, etc. The level of children's cultural capital was measured by their cultural activities, such as going to museums, and playing musical instruments. Children's personal characteristics and placement history in out-of-home services were used as control variables. We found that among personal characteristic variables, self-esteem, depression and anxiety, and delinquency affected the academic achievement of the children. Cultural capital, but not social capital, positively affected the level of academic achievement of the children. Based on the study results, implications for child welfare practice were discussed.

기능성게임은 교육, 치료, 훈련 등과 같은 본연의 목표에 따라 이용자들에게 선택된다. 따라서 해당 게임은 게임 내 외부에서 목표의 성취 여부를 평가받게 된다. 기능성게임의 품질요소 가운데 평가성은 목표 성취여부를 파악하는 기능이 게임 내에 포함되어 있는가에 관한 것이다. 본 논문은 몇 가지 사례를 통하여 기능성게임의 성취도 평가 기능을 살펴보고, 나아가 영어 학습을 위한 기능성 게임을 개발할 때 활용할 수 있는 성취도 평가 기능을 레벨 시스템에 적용하여 설계하였다. 이 레벨시스템은 경쟁과 보상이라는 게임의 핵심 요소를 이용하였고 교육부 고시에 근거하여 이용자의 영어 수준에 따라 등급이 결정되도록 시뮬레이션을 거쳐 설계한 것이다. 본 논문은 성취도 평가기능을 포함한 영어게임 설계에 유용하게 참조될 것이다.

According to the requirement of wing weight estimation and frequent adjustments during aircraft conceptual design, a wing weight estimation method considering the constraints of structural strength and stiffness is proposed to help designers make wing weight estimations rapidly and accurately. This method implements weight predictions on the basis of structure weight optimization with stiffness constraints and strength constraints, which include achievement of wing shape parametric modeling, rapid structure layout, finite element (FE) model automated generation, load calculation, structure analysis, weight optimization, and weight computed based on modeling. A software tool is developed with this wing weight estimation method. This software can realize the whole process of wing weight estimation with the method and the workload of wing weight estimation is reduced because much of the work can be completed by the software. Finally, an example is given to illustrate that this weight estimation method is effective.

This study aimed to test method on the accuracy of estimating the items parameters and ability, using the Three Parameter Logistic. To achieve the objectives of the study, an achievement test in chemistry was constructed for third-year secondary school students in the course of "natural sciences". A descriptive approach was employed to conduct the study. The test was applied to a sample of (507) students of the third year of secondary school in the "Natural Sciences Course". The study's results revealed that the (EAP) method showed a higher degree of accuracy in the estimation of the difficulty parameter and the abilities of persons higher than the MML method. There were no statistically significant differences in the accuracy of the parameter estimation of discrimination and guessing regarding the difference of the two methods: (MML) and (EAP).

현재 인터넷을 활용한 웹에서의 원격 교육평가시스템은 많이 나와있으나, 학생 개개인의 특성과 성향을 고려하지 못하고 일괄적이고 전체적인 평가만을 실시하고 있는 실정이다 본 논문은 문제은행 데이터베이스를 구축하여 웹을 통해 학생이 시간과 장소의 제약 없이 평가를 실시할 수 있는 비동기 분배 커뮤니케이션(Distributed Asynchronous Communication)방법의 교육모델에 덧붙여서, 기존의 원격 교육평가 시스템에서는 소홀히 다루었던 학생의 개인차와 특성을 고려한 사용자 프로파일을 이용하여 문제를 필터링한 후 출제하여 평가의 질적인 향상 및 학생의 학력을 향상시키는 효과적인 방법을 제시한다. 이것은 DAC 방식을 발전시킨 적응력 있는 DAC 방식이라 한다.

Objectives: This study was conducted in order to develop a computerized test to measure the level of mathematic achievement and related cognitive functions in children and adolescents in South Korea. Methods: The computerized Comprehensive Learning Test-Mathematic (CLT-M) consists of the whole number computation test, enumeration of dot group test, number line estimation test, numeral comparing test (magnitude/distance), rapid automatized naming test, digit span test, and working memory test. To obtain the necessary data and to investigate the reliability and validity of this test, 399 children and adolescents from kindergarten to middle school were recruited. Results: The internal consistency reliability of the CLT-M was high (Cronbach's alpha=0.76). Four factors explained 66.4% of the cumulative variances. In addition, the data for all of the CLT-M subtests were obtained. Conclusion: The computerized CLT-M can be used as a reliable and valid tool to evaluate the level of mathematical achievement and associated cognitive functions in Korean children and adolescents. This test can also be helpful to detect mathematical learning disabilities, including specific learning disorder with impairment in mathematics, in Korea.
