The purpose of this study is to develop a test and verifying the validity and reliability for measuring a effectiveness of e-earning course in cyber university. Twenty-five items were developed based on literature review and were examined by experts in the field. For item analysis, EFA(Exploratory Factor Analysis) was performed with 768 students in first study. In order to validate the test, CFA(Confirmatory Factor Analysis) was conducted with 791 students in second study. The result of the study yielded five factors with 25 items: 1) contents and design, 2) instructor, 3) system, 4) evaluation, and 5) overall course satisfaction. And this research reports the reliability and validity of new test.

The purpose of this study is to develop a mathematics self-efficacy test tool for elementary school students based on the sub-factors of mathematical self-efficacy derived from current studies. In this study, I verified the validity and reliability of the test tool by statistically evaluating the results of applying the test tool to the 3rd-6th grade students. In this study, Principal Component Analysis was performed on the tool for measuring the self efficacy of mathematics for elementary school students. For the validity test, the mathematics anxiety status of the participants was measured. The mathematics anxiety who were known to have a negative correlation with the mathematical self efficacy. The mathematics self efficacy tool developed in this study consists of 16 items with three subcategories: master experience, social persuasions, and emotional and physiological state. The mathematical self efficacy test tool developed in this study is expected to provide grounds for diagnosing the mathematics self-efficacy status of elementary school students and looking for ways to improve it.

This study aims to develop a highly-reliable inventory for measuring and analyzing the positive psychological experience in math learning. A measurement result provides meaningful information on the strength of students. Elements of positive psychological experience in math learning were extracted by the extensive research on the literature. The result was verified through the open survey. Through this process, the first preliminary questionnaire of 106 items was released, and was revised into the second one of 66 items through a continuous investigation on reliability and validity. Finally, a measurement inventory with 65 questions for testing 'positive psychological experience in math learning' was established.

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.

Objects：This study was carried out to develop the Korean form of Moral Development Inventory for Adolescents designed to assess the principled morality in adolescents. And the auther also intended to find the demographic variables that influence the moral development. Methods：The Korean form inventory was applied to 507 middle and high school adolescents, and retest was done in 42 second year middle school adolescents with 3 weeks interval. Together this inventory, short form of Rest moral development which had been proved its reliability and validity, were administered to the all subjects for concurrent validity. And then the author examined whether this inventory discriminates between conduct disorder patients, psychiatric controls and normal controls in the level of moral development. Results：Test-retest reliability and internal consistency were very satisfactory. Concurrent validity with this inventory was also high level. And conduct disorder patients were scored significant lower than psychiatric and normal controls in the level of principled morality. The mean PM scores did not show significant difference according to the variables such as sex, birth order and religion. But there was significant difference according to the educational level of mother and places. Conclusions：These results indicate that the Korean form of Moral Development Inventory is a reliable and valid rating inventory to assess the moral development level in Korean adolescents.

Objective : The purpose of this study is to investigate trend in use of occupational therapy assessment tools used by pediatric occupational therapist. Methods : Survey questionnaire developed for this study were used to for data collection. The questionnaires are divided into 10 area: occupational performance, activities of daily living, education, play, sensory-perceptual, motor and praxis, cognition, social interaction skills, development, and physical examination. Total 105 responses were analyzed using descriptive statistics analysis and frequency analysis. Results : For the general process of evaluation in pediatric occupational therapy, major response on the initial evaluation time was 30~60minutes (41.9%), and major response on the re-evaluation period was 3~6months (41.0%). The major assessment tool for each area Canadian Occupation Performance Measure (55.2%) for occupational performance assessments, Wee Functional Independence Measure (57.1%) for activities of daily living assessments, School Function Assessment (2.5%) for education assessments, Knox Preschool Play Scale (28.6%) for play assessments, Developmental Test of Visual Perception (94.3%) for sensory-perceptual assessments, Bruininks-Oseretsky Test of Motor Proficiency (42.9%) for motor and praxis assessments, Evaluation of Social Interaction (6.1%) for social interaction skills assessments, Denver Developmental Screening Test (92.4%) for development assessments, Clinical Observation (89.5%) for physical examination assessments. Conclusion : The study identified the most assessment tools used for specific area by pediatric occupational therapists. The results can be used as a basic data to educate about pediatric occupational therapy evaluation, as well as to develop new assessment tools in pediatric setting in future.

비디오 강의를 활용한 온라인 학습은 교육 효과를 높이는 무한한 가능성을 가지고 있지만 온라인에서 학습자 주도로 이루어지기 때문에 학습 동기를 높이고 온라인 강의에 집중시킬 수 있는 도구의 개발이 필요하다. 또한 교수자는 온라인 환경 안에서 학습자가 실제로 학습을 수행했는지에 대한 여부를 쉽게 파악할 수 있는 도구의 개발이 필요하다. 본 논문은 학습자와 교수자의 요구를 만족 시킬 수 있는 단어게임 기반의 온라인 비디오 학습 자동 판단 시스템을 개발하였고, 시스템 검증을 위해 343명의 학습자를 대상으로 사용자 만족도 설문조사를 수행하였다. 설문 결과, 83%의 시스템 용이성, 73%의 시스템 만족도로 긍정적인 결과를 보였다.
