This preliminary study aimed to develop 3 assessment scales for self-evaluation by day care directors and teachers. The development of major areas of evaluation and items as well as evaluation criteria for each item was based on the analysis of related research and major evaluation instruments. A panel of experts in early childhood education examined the contents. The 3 preliminary scales were administered in 87 day care centers; data were analyzed by item response distribution, item discrimination, and reliability of the scales. Items indicating low item discrimination were deleted and minor revisions were made to improve psychometric characteristics of each scale. The final version of the 3 scales is valid for use as self-evaluation instruments by day care directors and teachers.

이 연구에서는 2009 개정 교육과정에 따른 고등학교 융합형 '과학' 교과에서 사용된 선다형 평가 문항의 특성을 분석하였다. 문항의 출제 경향을 분석하기 위해 융합형 교과에 특이적인 분석틀을 구안하여 분석하였으며, 문항 반응 이론을 적용하여 문항의 특성을 양적으로 분석하였다. 문항의 출제 경향 분석 결과, 문항 출처, 융합 범위, 인지 수준 측면에서 융합형 '과학' 교과의 취지를 제대로 반영하고 있지 못하는 것으로 나타났으며, 기존 교육과정의 과학 교과와 같은 분과적 교수-학습 및 평가가 이루어지고 있음을 알 수 있었다. 문항 반응 이론을 적용한 분석 결과, 대체로 문항의 난이도는 적절하며, 변별도는 높은 수준인 것으로 나타났다. 하지만 분석틀을 구성하는 3개 범주와의 연관성은 나타나지 않았다. 이와 같은 연구 결과를 토대로 융합형 '과학' 교과의 취지를 반영한 교수-학습과 평가를 위한 개선점을 논의하였다.

The purpose of this study is to investigate the assessment expertise of Mathematics' teachers, focusing on the competence in designing assessment item development. In this present research, I analysed how the teachers' competence appears in designing assessment items development when they generated problems the given problem into a new one. To examine this assumption, the following research questions were posed and investigated in the present study : How do Pre-service and In-service Teachers in primary schools develop the assessment item when generating problems the given problems into new problems? The result from the case study of metamorphosing the given problem into a new problem teachers used similar patterns switching numbers or changing units in order to develop new problems. Also, teachers in primary schools tend to develop problems as commonly as in the mathematics workbooks. In-service teachers tend to have better skills developing assessment items, but there were quite much of variability between individuals.

A versatile dimensionality assessment index DETECT has been developed for binary item response data by Kim (1994). The present paper extends the use of DETECT to the polytomously scored item data. A simulation study shows DETECT performs well in differentiating multidimensional data from unidimensional one by yielding a greater value of DETECT in the case of multidimensionality. An additional investigation is necessary for the dimensionally meaningful clustering methods, such as HAC for binary data, particularly sensitive to the polytomous data.

Background: The Functional Gait Assessment (FGA) was developed to measure of gait-related activities. The FGA was translated in Korean but only a few psychometric characteristics had been studied. Objects: The purpose of this study was to evaluate the validity and reliability of the Korean version of FGA scale using Rasch analysis. Methods: The study included 120 patients with stroke (age range=30~83 years; mean${\pm}$standard deviation=$58.3{\pm}11.1$). The FGA and Berg Balance Scale were performed, and were analysed for dimensionality of the scale, item difficulty, scale reliability and separation, and item-person map using Rasch analysis. Results: The 4 rating scale categories of FGA were satisfied with optimal rating scale criteria. The most items of the FGA showed sound item psychometric properties except 2 items ('gait with the horizontal head turns', and 'gait with narrow base of support'), and the 2 misfit items were excluded for all further analyses. The 8 items were arranged in order of difficulty. The most difficult item was 'gait with eyes closed', the middle difficult item was 'gait level surface', and the easiest item was 'gait with vertical head turns.' A person separation reliability was .93 and the person separation index was 3.57. Conclusion: This study suggests that the 8-item Korean FGA are valid measure of assess the gait-related balance performance, and to set the goal of rehabilitation plan in patient with stroke.

Good assessment is crucial for feedback on curriculum and to motivate students to learn. This study was conducted to perform item analysis on the Medical Education Assessment Consortium clinical knowledge mock examination (MEAC CKME) (2011-2016) and to evaluate several effects to improve item quality using both classical test theory and item response theory. The estimated difficulty index (P) and discrimination index (D) were calculated according to each course, item type, A (single best answer)/R (extended matching) type, and grading of item quality. The cut-off values used to evaluate P were: >0.8 (easy); 0.6-0.8 (moderate); and <0.6 (difficult). The cut-off value for D was 0.3. The proportion of appropriate items was defined as those with P between 0.25-0.75 and D ${\geq}0.25$. Cronbach ${\alpha}$ was used to assess the reliability and was compared with those of the Korean Medical Licensing Examination (KMLE). The results showed the recent mean difficulty and decimation index was 0.62 and 0.20 for the first MEAC CKME and 0.71 and 0.19 for the second MEAC CKME, respectively. Higher grade items evaluated by a self-checklist system had better D values than lower grade items and higher grade items gradually increased. The preview and editing process by experts revealed maintained P, decreased recall items, increased appropriate items with better D values, and higher reliability. In conclusion, the MEAC CKME (2011-2016) is deemed appropriate as an assessment to evaluate students' competence and prepare year four medical students for the KMLE. In addition, the self-checklist system for writing good items was useful in improving item quality.

Objective: This study aims to develop CFT, a screening test for dementia that can be conducted on patients with mild cognitive impairment or early dementia. Methods: This study was conducted on therapists working at occupational therapy hospital in Gyeongsangnam-do. The data collection period is two months from July to September 2020, and the research participants were briefed on the purpose, significance, and anonymity of the research in consideration of ethical issues. A total of 33 copies of the data were finally analyzed, excluding those containing insufficient answers and errors, by distributing 40 copies of the data. SPSS Data Access pack 8.0 was used for data analysis, Cronbach's α value was evaluated for internal consistency reliability of each item, and Pearson Correlation coeffient between the lower scales of the assessment tool was measured. Results: The Cronbach's α value of the CFT was shown as .892 and the reliability of the assessment paper was shown to be quite high. The Cronbach's α value for each item in the cognitive assessment tool was the highest at .899 in the subtraction item, with exercise control (mook Chi Pa) at 888, visual memory, plus .887. The correlation of each item of cognitive assessment tools was found to be most correlated with the number of sustained concentrates and word2 to .934; in the stop word-numeric item and visual memory to be .85; and in the addition to the auditory memory item .739. Conclusion: Therefore, this study developed cognitive evaluation tools that can distinguish the diversity and cognitive level of screening tests and clarify standards, which are different from the existing dementia screening tools in Korea. Furthermore, the cognitive assessment tools of this study can be verified by applying them to patients with mild cognitive impairment and early dementia, and the criteria for generalization can be established.
