수학 교육평가에서 고사 타당도의 측정은 매우 중요하다. 그것은 평가자가 목적하는 바의 준거에 따라 수험자들의 문제해결력 변별을 위한 고사들 간의 타당도 크기 측정과 또는 고사 문항의 선정, 배치를 통하여 한 고사의 타당도를 높이기 위한 문항별 타당도 계수를 측정 계산하는 것이다. 이 연구에서는 이 두 가지 고사 타당도의 크기 측정법을 이용하여 수학교육 평가 현장에서 직접적으로 적용할 수 있는 고사 타당도의 제고에 유효한 연구 결과를 제시한다.

본 연구 논문은 영 유아를 대상으로 한 사회 정서 문제의 선별 평가서인 Ages and Stages Questionnaire: Social-Emotional (ASQ:SE)의 표준화(신뢰도 및 타당도)연구이다. 특히, ASQ:SE 질문지 가운데에서도 24개월과 36개월용을 이용하여 ASQ:SE 의 내적 일치도 (internal consistency reliability), 재검사 신뢰도 (test-retest reliability), 절선 점수 (cutoff points), 공인 타당도 (concurrent validity)에 대해 연구하였다. 전체 447명의 부모가 참여한 가운데, 237명은 24개월용 질문지를 작성했고, 210명은 36개월용 질문지를 작성했다. 내적 일치도는 24개월 질문지에서 71, 36개월 질문지에서는 .73이었다. 재검사 신뢰도는 24 개월 질문지에서 100%, 36개월 질문지에서 97%이었다. 마지막으로 공인 타당도는 24개월과 36개월 설문지에서 95%이었다. 끝으로, 추후 다양한 대상으로 연구될 것이 추천되며 또한 이 연구에서 제외되어졌던 연령의 ASQ:SE 질문지의 내적 일치도, 신뢰도 및 타당도가 연구되어져야 할 것이다.

This study describes validity and reliability, which are important factors to obtain scientific results in the study of library and information science. Specifically, this paper starts by exploring the definition and types of validity and reliability. It then analyzes the factors which affect to validity and reliability in developing test-items through the previous studies. It is proposed that validity and reliability be regarded as basic and important components to solve problems related to library and information science in the future scientifically.

Approximate number sense(hereafter, ANS) is the ability to compare and operate upon numerosity information. The numerosity comparison task is used to measure ANS. However, there is considerable variance among previous reports of ANS acuity which may be related to different task formats used. Here, we aim to investigate whether the format of the numerosity comparison task influences measurements of ANS acuity. We compared two task formats; 1) an intermixed format presenting two intermixed arrays of black and white dots, and 2) a side-by-side format showing two arrays of dots side by side. The intermixed format likely makes additional demands on general cognitive resources for inhibitory control, selective attention, or visuospatial working memory. The performance on the intermixed format was significantly lower than that of the side-by-side format resulting in an underestimation of ANS acuity compared to the expected trajectory of ANS development. In addition, the ANS acuity measured from only the side-by-side format was correlated with children's mathematical achievement and age. Our results demonstrate that measurement of ANS from the side-by-side format has higher construct and predictive validity compared to that of the intermixed format.

Objective : The purpose of this study to create a translation of Life Space Assessment(LSA) for elderly, which was then tested for content related validity and understanding test. Methods : The translation and content validation process involved direct and backward translation, and the collection of content-related evidence from 6 expert panels and 13 clinician panels. A content validity indices (CVI), means, and standard deviations were used for the analysis of the content validity. Results : The results of the comparison between the original LSA and the Korean LSA with the expert panels were I-CVI showed a very high value of .93. and 1.00, and S-CVI/Ave 0.99. The results of the understanding test were showed a very high value of .92 and 1.00, and S-CVI/Ave 0.97. Conclusion : Korean LSA showed content related validity and understanding test, and illustrated the applicability of LSA in a Korean clinical setting. The results showed LSA can be used a useful tool for evaluating the community mobility of elderly.

이 연구는 현존해 있는 다양한 임상평가도구의 신뢰도와 타당도에 관한 분석 서술 연구이다. Rines(1974)에 의하면 평가는 학습경험을 통하여 목적을 달성하는 지의 여부를 측정하는 것이라고 하였고 평가의 목적은 교육증진을 도모하며, 목표를 설정하고, 학생의 학습진행과정을 사정하여 학생들을 위한 프로그램을 사정, 개발시키는데 있다고 피력 하였다. 간호교육에는 실무교육이 많은 비중을 차지하고 있다. 또한 많은 간호교육자들은 실습평가에 있어 많은 어려움을 경첩하고 있다. 이러한 난해한 실습평가도구를 개발하기 위하여 선행된 우선순위로써 현존해 있는 다양한 평가도구의 신뢰도와 타당도를 평가하는 것이 의의 있는 일이라 사료된다. 이 논문은 실습평가도구의 신뢰도와 타당도에 관심을 가진 임상지도교수나 간호교육자들을 대상으로 한 서술적 연구이다. 우선 간호교육평가에 있어서의 문제점을 분석하고 평가도구에 대한 전문가(Authority)의 의견을 피력한 다음 저자의 의견을 서술하였다. 결론적으로 현재까지 개발된 완전한 임상실습평가의 방법은 없다. 그러므로 현존해 있는 평가방법을 서술평가하고 문제점을 지적하므로써 질적인 평가도구개발에 도움을 줄 수 있다. 앞으로 간호교육자들이 각 문제점들을 보완하여 교육목적을 달성시킬 수 있는 효율적인 평가도구를 개발하는 것이 급선무이다.

The purpose of this study was to examine the reliability and validity of Stroke Impact Scale 3.0 (SIS 3.0). Here, the SIS 3.0 was completed by 154 stroke patients (mean = 62.7; standard deviation [SD] = 9.43). Construct validity was verified by analyzing the correlation between SIS 3.0 sub-domains, and convergent validity was investigated by analyzing the correlation between the Modified Barthel Index (MBI) and the Mini-Mental State Examination-Korean (K-MMSE) version. The characteristics of each item were analyzed by internal consistency and item discrimination based on the classical item theory. Construct and convergent validity were verified through this study. Although the item i included in the emotion domain showed low item discrimination, all but this item showed high discrimination. Internal consistency was also high in all sub-domains.

The present study is a basic study for application of Augmented Reality (AR) to verb teaching for children with language developmental disorders and is intended to examine validity for the list of verbs at the beginning of development. To confirm the validity of the verbs list, the appropriateness of the verbs was evaluated by three professors with certification of KSLP (Korean Speech-Language Pathologist) working in the department of Speech-Language Pathology at the university. The motion validity test was conducted by showing motion implemented as AR to eight master's students in Speech-Language Pathology major, having them record verbs that came to their mind, and evaluating in the conformity. The second motion validity test was conducted by using 5-point Likert scales to 87 undergraduates in Speech-Language Pathology major and having them see the motions in AR and marked the degrees to which them see the motions conform to the relevant verbs on the scales. Using the SPSS 21.0 program, descriptive statics analyses of the results were conducted. Through this all process, thirty verbs were selected as having content validity. It could be seen that when AR based communication system are applied, things and backgrounds that complement the insufficient movements of motions and help motion recognition should be also provided. In future studies, the 3D images of the AR based communication system will be complemented and the content validity will be verified with typically developing children and the children with language developmental disorders.

The purpose of this study is to conduct the Korean translation and validity of the Unconditional Positive Self-Regard Scale(UPSR) that Patterson and Joseph(2006) originally developed based on the Rogerian person-centered theory. K-UPSR was adapted, modified and validated from the UPSR Scale. This study verified reliability and validity, and factor structure of K-UPSR. The preliminary study was proceeded with twelve adapted questions to 131 undergraduate and graduate students. As a result, three questions were deleted for the low reliability. The exploratory factor analysis of the nine questions showed two sub factors. The internal consistency reliability of nine questions with two sub factors was .89 in this study. The study was conducted by 419 male and female adults and verified confirmatory factor analysis and the validity. The study data was evaluated for the suitability of convergent and discriminant validity of K-UPSR. Through the correlation analysis of other five scales, the result was mostly corresponded to the preliminary study.

We sought to develop a multi-dimensional tool for measuring and understanding nurse fatigue. The participants were 301 nurses working in four hospitals in Seoul, South Korea. Basic items were developed after a preliminary literature review, and content validity was verified by a group of experts. The first 52 items from which the fatigue measurement tool was to be developed were tested for construct validity and were reduced via factor analysis to 31 items. Following a confirmatory factor analysis, the items were further reduced to 23 items in three categories: physical, mental, and emotional. A confirmatory factor analysis found the items to be adequate. The fatigue scale was found to have high construct validity and reliability. This scale is expected to serve as a preliminary data-gathering tool to assess the level of nurse fatigue and to develop interventions to alleviate it.
