웹 기반 학습(WBI)은 인터넷의 빠르게 확산되어 가고 있다. 또한, 학습자의 학습효과를 높이기 위한 많은 연구와 기술들이 적용되었다. 그러나, 대부분의 웹 기반 학습 시스템은 문제은행에서 반복적인 학습내용의 제공이나 학습의 패턴을 주는 학습자료 제공자 측면에서의 일방적인 학습방법을 택하고 있다. 시스템의 개발방법에서도 웹 기반 학습시스템은 전통적인 순차적 프로세스 개발방법에 따라 구현됨으로서 개발의 비효율성 밀 재사용, 유지보수등이 어려웠다. 본 연구에서는 문제은행에서 사용되는 문제추출 컴포넌트를 설계 및 구현하였다. 문제추출은 학습자의 학습효과를 높이기 위하여 문항난이도를 분석하여 학습자에게 적절한 문제가 출제될 수 있도록 하였다. 또한, 본 연구의 시스템에서 중요한 비즈니스 로직이 되는 난이도 분석 및 적용부분은 EJB컴포넌트로 구현함으로서 구현로직의 분리 및 재사용성, 유지보수성을 높였다.

학교에서 실시되는 평가의 주체는 교사이므로, 교사는 '좋은 평가 도구'를 개발 ${\cdot}$ 제작 할 수 있어야 한다. 좋은 평가 도구를 제작하기 위해서는 이에 대한 직접적인 훈련이 필수적인 동시에 교사 교육의 첫 단계부터 좋은 평가 도구로 평가를 받는 간접 경험도 중요하다. 이 논문에서는 문항반응이론을 적용하여 수학교사 양성기관에서 사용되는 지필고사 문항에 대하여 신뢰도, 타당도, 난이도 및 변별도를 측정하였다. 이 결과는 평가 문항을 개발할 때에 기초자료로 사용될 수 있다.

Objective : The aims of the this study is to identify job characteristics, to generate job description, and additionally to investigate duty task of the job for Korean pediatric occupational therapist focused on sensory integration intervention. Methods : In the first stage, job analysis of pediatric occupational therapist focused on sensory integration intervention was performed by an advisory committee consist of the DACUM panel. Through the job analysis, job description with definition was established. In the second stage, a survey was performed for 141 pediatric occupational therapist using a questionnaire based on the job description in order to investigate importance, frequency and difficulty of duty task and task elements of the job. This process was done from May to September 2017. Results : The job definition drew from this study was 'Pediatric occupational therapist provides occupational therapy services to children and adolescents to support occupational performance and social participation including daily activities and play". Through the job description established in this study, 9 duties (consulting, evaluation, intervention plan, intervention, document, education, self-development, management, and administration), 28 tasks and 169 task elements were drew. In the survey, among the duty tasks and task elements, 'ensure physical safety' and 'perform a session' were selected as the most important task, and 'ensure safety of children, sensory integrative equipment and environment' and 'prepare a safe environment' were selected as the most important element. Conclusion : This study defined job demands and characteristics of pediatric occupational therapist who performs sensory integration intervention. It is expected that this study can be used a resource to develop and/or improve educational program related.

Purpose: The purpose of this study was to describe the job performance, importance, and difficulty in Surgical Clinical Practice Nurses (SCPNs), and to identify the priority of job tasks using Importance-Performance Analysis (IPA). Methods: One hundred SCPNs were recruited from two university hospitals and two general hospitals during November 2021 to April 2022. A total of 97 data were analyzed excluding 3 data due to missing responses. The data were analyzed by two groups, with Ward-Based SCPNs (W-SCPNs) and Operation Room-Based SCPNs (OR-SCPNs) according to different characteristics of job tasks. Results: There were differences of job performance between W-SCPNs and OR-SCPNs. As a result of the IPA, tasks of 'working practices in the ward' for W-SCPNs and those of 'surgery and treatments' for OR-SCPNs were included in the first quadrant (keep up the good work). 'Resarch' and 'leardership' were included in the third quadrant (low priority). Conclusion: Since there are differences in job tasks between W-SCPNs and OR-SCPNs, health care institutions should consider the differences in defining the scope of job performance. Furthermore, it is necessary to develop customized continuing education program based on our findings of IPA.

There have been problems regarding decreased productivity and inherent safety risks due to apprentice facility operators receiving training without a standardized education system, especially for container crane operators. This study aims to propose alternatives to educate and manage container crane operators systematically in accordance with a job analysis. The Job analysis was professional panels and a Developing A Curriculum(DACUM) facilitator. The job description on the DACUM research chart for container crane operators contained 6 duties and 42 tasks. We surveyed problems with the existing education process for container crane operators; performed job analysis according to DACUM based on the survey results, and finally developed job description, education courseware and a summary table.

This study aims to evaluate of validity and reliability of the job performance tool already developed for the elementary school health teachers. 305 health teachers responded to the questionnaire composed of 50 items. The validity and reliability of the tool were verified by confirmatory factor analysis. That were composed of 8 sub-categories and had 4 factors. The importance, frequency, and difficulty of the four factors were classified according to the questionnaire criteria, but the importance of health promotion is classified as one new item factor. The statistical significance of the fit of the model was 3.664 (df = 246, p<0.001), RMSEA=0.09, NFI=0.85 and CFI=0.88. The internal consistency of the subscales was Cronbach's ${\alpha}$ of 0.88 to 0.96. The internal consistency of the subscales, Cronbach's ${\alpha}$ was 0.88~0.96. This study shows that the analysis tool for primary school health teacher is valid and reliable as a measurement tool.

College Scholastic Ability Test(CSAT) is a primary test to evaluate the study achievement of high-school students and used by most universities for admission decision in South Korea. Because its level of difficulty is a significant issue to both students and universities, the government makes a huge effort to have a consistent difficulty level every year. However, the actual levels of difficulty have significantly fluctuated, which causes many problems with university admission. In this paper, we build two types of data-driven prediction models to predict correct answer rate and to identify significant factors for CSAT English test through accumulated test data of CSAT, unlike traditional methods depending on experts' judgments. Initially, we derive candidate question-specific factors that can influence the correct answer rate, such as the position, EBS-relation, readability, from the annual CSAT practices and CSAT for 10 years. In addition, we drive context-specific factors by employing topic modeling which identify the underlying topics over the text. Then, the correct answer rate is predicted by multiple linear regression and level of difficulty is predicted by classification tree. The experimental results show that 90% of accuracy can be achieved by the level of difficulty (difficult/easy) classification model, whereas the error rate for correct answer rate is below 16%. Points and problem category are found to be critical to predict the correct answer rate. In addition, the correct answer rate is also influenced by some of the topics discovered by topic modeling. Based on our study, it will be possible to predict the range of expected correct answer rate for both question-level and entire test-level, which will help CSAT examiners to control the level of difficulties.
