  • The purpose of this study was to analyse the relationships between cognitive abilities and driving characteristics of elderly drivers. Driving characteristics of elderly and younger drivers who were driving a fixed base driving simulator vehicle were examined. Participants consisted of 12 drivers over age 65 (the 'older' group) and 12 drivers between the ages of 25 and 55 (the "younger" group). As indices of cognitive ability, critical flicker fusion frequency (CFF) tests and cognitive reaction tests were given before the driving task. CFF was also tested after the simulated driving task for both groups. Cognitive reaction tests, which were composed of speed estimation tests, multiple choice reaction tests and obstacle avoidance tests, were developed by the Korean Road Traffic Safety Authority in 2003. CFF values between the two groups exhibited significant differences both before and after the task, with a p-value less than 0.01 and a t-value of -3.01 before the test and a p-value less than 0.031 and a t-value of -2.35 after the test. Older drivers' CFF values were lower than those of the younger. However, there was no difference in older or younger driver CFF values before and after the task within the same group. Except for the multiple choice reaction test, there was no difference in cognitive reaction test results between the two groups. The elderly drivers made more errors though they did not differ from the younger drivers in reaction times. At the simulated driving task the reaction time of the elderly driver was longer than that of the younger; however, the driving speed of the elderly was lower and the number of collisions greater. There was a positive correlation (r=.496) between the number of errors in the multiple choice reaction test and the number of collisions in the driving task. Therefore, it was identified that critical attributes contributing to automobile crashes involving elderly drivers included cognitive difficulty in judging and responding to complex situations.

  • The present study aims to demonstrate that it is possible to objectively evaluate the competency (referred to as graduate attributes or program outcomes) of graduates of engineering education programs. To strengthen the link between engineering education accreditation and the qualification/certification system of engineering professionals, referred to as K-Engineering Professional (K-EP), individually assuring the quality of accredited graduates using multiple-choice test as main assessment tool is proposed. Test questions related to the basic vocational skills of NCS are developed for seven of the 10 program outcomes of the ABEEK KEC2015. The three program outcomes, PO1, PO3, and PO5, which need to fully accommodate the characteristics of each disciplinary field, are excluded. A pilot test involving graduates of eight accredited programs is conducted. Applying on Rasch model based on Item Response Theory (IRT), the item difficulty, fit and discrimination of multiple choice test are demonstrated. The pilot study strongly suggests that individual competency evaluation is possible at a certain level for seven program outcomes tested. For PO1, PO3, and PO5, however, questions that address the characteristics of each disciplinary field need to be devised. If a suitable pool of questions is built, it can be used as a program outcomes assessment tool by the accredited programs.

  • Since the establishment of the national medical licensing examination board in 1992, the medical licensing examination system has changed enormously and this has had a number of impacts on examination services. All those reforms were aimed at improving the relevance and reliability of the test. Several attempts of the testing system have appeared in the new examination service, and which have also brought about the changes in the medical school curriculum such as introducing integrated courses instead of traditional subjects, using test scores as a reference to the post-graduation selection test. Some examples of changes in the examination system are as follows: 1) choosing three integrated test subjects and outlines of their reference content instead of 15 academic subjects, 2) adjusting the ratio of multiple choice question items to focus more on the problem solving level, 3) introduction of 'one-best answer' single set and 'extended matching type items, 4) item construction based on real clinical cases and real clinical materials. Recently, a clinical skill test system has been introduced to measure examinees' basic clinical skills competencies. Despite continuing efforts, the examination system still has many issues remaining to be solved. These problems include the differential weighting of test items, appropriate threshold for passing, and practicality of pre-testing to stabilize the passing rate and avoid the hazards of newness and undesirably difficult test items.

  • The goal of this study is to examine the level of disposition conformity in everyday life and behavior conformity in clothes brand choice, and analyze the effects of disposition conformity and influential variables on behavior conformity in brand choice. For this analysis, the data were collected from 478 middle school and high school students in Seoul through surveys. Frequency, percentage, mean, standard deviation, Pearson's correlation coefficient, ANOVA, t-test, Duncan's multiple range test and multiple regression have been used to analyze the research objectives. Main findings are following; First, the 62.8% of the students showed high level of disposition conformity, and the 60.7% of them showed relatively low level of behavior conformity in brand choice. The adolescent consumers'disposition conformity to the reference groups in everyday life is in the order of parents, peer group, and mass media star. Second, the group differences in disposition conformity are diversified by independent variables. Among socio-demographic variables, disposition conformity to peer group differ by grade and disposition conformity to parents differ by the parents'education. Sex causes differences between groups in all disposition conformity except parents. In economic variables, the perceived level of living raises differences between groups in disposition conformity to the parent and whole disposition conformity. As the degree of disposable money gets higher in buying clothes, adolescent consumers conform more to the mass media star. Disposition conformity to parents and peer group were also differed by self-esteem. Third, significant variables, which affect the adolescent consumers'behavior conformity in brand choice, are grade, their mother's education, degree of disposable money in buying clothes, and disposition conformity to peer group and mass media star.

  • 이 연구는 기존의 다중지능 검사의 문제점을 극복하고, H. Gardner의 다중지능에 관한 심리측정 원리들을 반영하여 개발한 한국형 다중지능 진단도구의 타당화 연구이다. 검사는 유아용, 초등학교 저학년용, 초등학교 고학년용, 중학생용, 고등학생용, 총 5종의 검사로 구성되었고, 검사의 형식은 검사시행 시점까지의 성취를 재는 선택형 문항, 능력을 재는 진위문항, 능력과 흥미를 재는 자기보고식 리커르트 척도 문항의 3가지 형식으로 구성하였다. H. Gardner의 심리측정에 대한 제언에 따라, 지능의 핵심요소에 대한 재검토, 지능들 간의 중복성 및 위계성 여부에 대한 검토, 지능 간 편파적이지 않은 문항 구성, 검사형식의 다양화 등을 지향했고, 특히 본 검사에서는 능력과 흥미와 성취를 포괄적으로 측정하고자 했다. 1, 2차 예비검사와 본검사를 통해 최종 표준화검사를 제작했고, 총 5585명의 연구대상을 연령별, 성별, 지역별로 구분하여 표집하고, 이를 통해 규준점수를 추출하여, 연령별 상대적 비교를 할 수 있도록 하였다. 검사의 타당화를 위하여, 수검행동 관찰, 평균, 표준편차, 정답률, 신뢰도, 하위지능검사들 간의 상관, 지능별 진로선택의 평균순위에 대한 Kruskal-Wallis 검증 등의 분석을 하였다. 하위지능 간 상관분석 결과, 본 검사는 지능 간 독립성 가정을 지지했고, 지능별 진로선택에 관한 비모수 통계검증 결과, 다중지능이 진로선택의 계열과 대체로 관련이 있음을 확인할 수 있었다. 본 연구는 언어와 논리수학 능력에 유리하던 종래의 검사들과 달리, 지능별로 문항이 공평하도록 노력했고, 객관화할 수 있는 능력문항과 규준점수를 개발한 것, 능력과 흥미와 성취 점수들 간의 비교를 통한 교육적 처방 및 상담을 위한 방편을 마련한 것에서 시사점을 찾을 수 있다. 그러나 검사시행의 현실적인 제약으로 문항수가 적게 개발되어, 요인분석이나 서로 다른 형식의 검사간의 상관분석 등을 하지 못한 데에는 한계가 있다. 따라서 향후 문항 수를 늘려 전체 검사를 두 차례로 나누어 시행하는 연구를 하면 요인분석 및 기타 여러 타당화 증거들을 보완할 수 있을 것이다.

  • Purpose: To develop a Critical Thinking Skill Test for Nursing Students. Methods: The construct concepts were drawn from a literature review and in-depth interviews with hospital nurses and surveys were conducted among students (n=607) from nursing colleges. The data were collected from September 13 to November 23, 2012 and analyzed using the SAS program, 9.2 version. The KR 20 coefficient for reliability, difficulty index, discrimination index, item-total correlation and known group technique for validity were performed. Results: Four domains and 27 skills were identified and 35 multiple choice items were developed. Thirty multiple choice items which had scores higher than .80 on the content validity index were selected for the pre test. From the analysis of the pre test data, a modified 30 items were selected for the main test. In the main test, the KR 20 coefficient was .70 and Corrected Item-Total Correlations range was .11-.38. There was a statistically significant difference between two academic systems (p=.001). Conclusion: The developed instrument is the first critical thinking skill test reflecting nursing perspectives in hospital settings and is expected to be utilized as a tool which contributes to improvement of the critical thinking ability of nursing students.

  • In the era of the outcome-based education, multiple-choice test has been widely employed owing to its efficiency that enables educators to evaluate a quantity of students with much objectiveness. However, the prevalent test has not been reconsidered enough to overcome its apparent shortcomings: examiners' effort for developing plausible and faultless distracters defending from every falsification, and students' random guessing on key choices. For alleviating such defects, tiered test as an experimental format of multiple-choice tests has been suggested in science education. Since there has not accumulated much study on the implementation of tiered tests, our research aim is set to construct a framework suggesting statistical indexes for rationally discerning tiered units that develop an effective tiered test. Graded both by our tiered-scoring and by the conventional partial-scoring, the preliminary tiered test in secondary physics attests the improvement in its discrimination and difficulty distribution. The findings reveal that the two indexes discern effective tiered items: discrimination increase (Ct-p) and difficulty decrease (Dp-t). Based on the index information, 4 heterogeneous tier types are recommended in the content of secondary physics: directional manipulation, repeated calculation, diverse explanation, and plural variables.

  • This study has been performed to identify intelligent ability, reward choice in assumed situation of delay of gratification, and delay of gratification ability. The subjects for this study were 100 preschoolers between the ages of 4 and 5, their mothers, and 15 teachers of three day-care centers in Seoul. T-test, F-test, Correlation analysis and multiple regression analysis were used for data analysis. The main results of this study were as follows: First, preschoolers' delay of gratification ability by mothers' educational background was significant and delay of gratification ability by sex was significant. This means that mothers who had a higher educational background were positively related to preschoolers' delay of gratification ability. Second, in an assumed situation of delay of gratification, preschoolers' delay of gratification ability by reward choice was not significant. Third, delay of gratification by intelligent ability was significant. Fourth, the correlation among intelligent ability, reward choice in assumed situation of delay of gratification and delay of gratification ability were significant. Finally, preschoolers' delay of gratification ability was significantly influenced by two factors: reward choice in assumed situation of delay of gratification and preschoolers' intelligent ability.

  • Robustness rates for repeated measures pairwise multiple comparison procedures were investigated in a split plot design with one between- and one within-subjects factor using untrimmed and trimmed data. Five factors were manipulated in the study: distribution, sphericity, variance-covariance heteroscedasticity, total sample size, and sample size ratio. The Welsch test (W) and the Welsch test on trimmed data $(W_{RT})$ performed better than the other procedures, but had a liberal tendency. The trimmed difference score Bonferroni Procedure $(B_{DT})$ was a good choice in some conditions.
