大学考试试题质量的量化研究 总被引：1，自引：1，他引：0
考试试题质量是指测验人员所选样本对测试对象属性的测量程度,具体表现为教师编制试题的难易度、信效度以及区分度。本研究随机抽取河西学院2007-2008学年第二学期8个系的16门考试课程为研究样本,对考试结果进行统计分析。结果表明:(1)期末成绩和总评成绩分布大部分呈正态分布,部分考试成绩分布呈现出不对称和尖峰态;(2)期末考试成绩等级上,理科在优秀和良好的比例高于文科在同一等级上的比例,同时,理科在不及格上的比例高于文科。总评考试成绩等级上,理科在优秀和良好的比例高于文科在同一等级上的比例,但是,理科在不及格等级上的比例低于文科,反映出平时成绩对总评成绩的随意性影响;(3)期末试题的难度系数高,试题难度较小,并且文理科和难度系数等级之间的卡方检验无显著的统计学意义;(4)期末试题区分度偏低,并且文理科和区分度系数等级之间的卡方检验无显著的统计学意义。 相似文献

与高等教育自学考试复本试卷平行性有关的因素主要有四类:试卷结构的、题目内容的、题目功能的和结果分数的。复本试卷内容上的平行是试卷平行性的前提与基础,对内容平行的判定主要通过专家判断题目的取样代表性来实现。对复本试卷总体分数的比较主要借助方差齐性检验和平均数差异显著性检验,还可通过雷达图比较同一专业下多个学科的水平变化。题目功能的平行主要借助难度分布和区分结构的比较,多个难度级别分值相差较大表明复本试卷未能满足平行性要求,不同区分功能类型的题目分值较为一致则表明试卷实现了区分功能的平行。 相似文献

Due to variation in test difficulty, the use of pre-fixed cut-off scores in criterion-referenced standard setting methods may lead to variation in grades and pass rates. This paper aims to empirically investigate the strength of this relationship. To this end we examine a dataset of over 500 observations from an institution of higher education in The Netherlands over the period 2008–2013. We measure variation in test difficulty by using students’ perceptions of the validity of the examination and by recording personnel changes in the primary instructor. The latter measure is based on the considerable variation in teachers’ ability to assess test difficulty that is found in the literature. Other explanatory variables are course evaluations, instructor evaluations and self-reported study time. Variation in student quality is controlled for by measuring course results in deviation from the cohort average. We take a panel approach in estimating the effect of the explanatory variables on the variability in grades and pass rates. Our findings indicate that exam validity and instructor change are significantly related to variation in test results. The latter finding supports the hypothesis that instructors’ difficulty in assessing test difficulty may introduce subjectivity in criterion-referenced standard setting methods. 相似文献

Two hypothesized models that represent relationships among test anxiety, perceived test difficulty, and test performance observed immediately before and after a final examination were tested. The structural equation modeling was used to examine the hypothesized relationships by imposing the structure of direct and indirect effects on the current data collected from 208 undergraduate students. Students' perception of test difficulty had a significant effect on the arousal of both worry and emotionality. Temporal changes were observed in the degrees of these relationships; while test difficulty perceived before and during the exam both had effects on test anxiety perceived at each corresponding time, students' perception of test difficulty during the exam had a greater direct effect on the arousal of test anxiety than did test difficulty perceived before the exam. Worry, but not emotionality, had a strong inverse relationship with performance. That perceived test difficulty did not have a direct effect on test performance, but had an indirect effect mediated by worry, indicates that test performance was not directly influenced by how they perceive the test difficulty, but worry aroused by the difficulty perception influenced their performance. Importance of understanding students' perceived test difficulty was discussed for its effect on arousing worry anxiety. 相似文献

Classroom research on achievement goals has revealed that performance-approach goals (goals to outperform others) positively
predict exam performance whereas performance-avoidance goals (goals not to perform more poorly than others) negatively predict
it. Because prior classroom research has primarily utilized multiple-choice exam performance, the first aim of the present
study was to extend these findings to a different measure of exam performance (oral examination). The second aim of this research
was to test the mediating role of perceived difficulty. Participants were 49 4th year psychology students of the University
of Geneva. Participants answered a questionnaire assessing their level of performance-approach and performance-avoidance goal
endorsement in one of their classes as well as the perceived difficulty of this class for themselves. Results indicated that
performance-approach goals significantly and positively predicted exam grades. Performance-avoidance goals significantly and
negatively predicted grades. Both of these relationships were mediated by the perceived difficulty of the class for oneself.
Thus, the links previously observed between performance goals and exam performance were replicated on an oral exam. Perceived
difficulty is discussed as a key dimension responsible for these findings. 相似文献

Collaborative Testing Improves Performance but Not Content Retention in a Large-Enrollment Introductory Biology Class 总被引：1，自引：0，他引：1

Collaborative testing has been shown to improve performance but not always content retention. In this study, we investigated whether collaborative testing could improve both performance and content retention in a large, introductory biology course. Students were semirandomly divided into two groups based on their performances on exam 1. Each group contained equal numbers of students scoring in each grade category (“A”–“F”) on exam 1. All students completed each of the four exams of the semester as individuals. For exam 2, one group took the exam a second time in small groups immediately following the individually administered test. The other group followed this same format for exam 3. Individual and group exam scores were compared to determine differences in performance. All but exam 1 contained a subset of cumulative questions from the previous exam. Performances on the cumulative questions for exams 3 and 4 were compared for the two groups to determine whether there were significant differences in content retention. Even though group test scores were significantly higher than individual test scores, students who participated in collaborative testing performed no differently on cumulative questions than students who took the previous exam as individuals. 相似文献

Traditional item analyses such as classical test theory (CTT) use exam-taker responses to assessment items to approximate their difficulty and discrimination. The increased adoption by educational institutions of electronic assessment platforms (EAPs) provides new avenues for assessment analytics by capturing detailed logs of an exam-taker's journey through their exam. This paper explores how logs created by EAPs can be employed alongside exam-taker responses and CTT to gain deeper insights into exam items. In particular, we propose an approach for deriving features from exam logs for approximating item difficulty and discrimination based on exam-taker behaviour during an exam. Items for which difficulty and discrimination differ significantly between CTT analysis and our approach are flagged through outlier detection for independent academic review. We demonstrate our approach by analysing de-identified exam logs and responses to assessment items of 463 medical students enrolled in a first-year biomedical sciences course. The analysis shows that the number of times an exam-taker visits an item before selecting a final response is a strong indicator of an item's difficulty and discrimination. Scrutiny by the course instructor of the seven items identified as outliers suggests our log-based analysis can provide insights beyond what is captured by traditional item analyses.
Practitioner notes
What is already known about this topic- Traditional item analysis is based on exam-taker responses to the items using mathematical and statistical models from classical test theory (CTT). The difficulty and discrimination indices thus calculated can be used to determine the effectiveness of each item and consequently the reliability of the entire exam.
- Data extracted from exam logs can be used to identify exam-taker behaviours which complement classical test theory in approximating the difficulty and discrimination of an item and identifying items that may require instructor review.
- Identifying the behaviours of successful exam-takers may allow us to develop effective exam-taking strategies and personal recommendations for students.
- Analysing exam logs may also provide an additional tool for identifying struggling students and items in need of revision.

The U.S. Department of Education measures student achievement through the National Assessment of Educational Progress (NAEP). NAEP estimates of population proficiency quantiles are based on a Bayesian multiple-imputation procedure. This article shows (a) that the resulting estimates depend directly on the mix of item difficulties on the test, and (b) the difficulty of items on the NAEP mathematics exam has increased over time. Does the increasing difficulty of the exam lead to observable changes in student performance over time? This study compared the simulated performance of 1990 examinees on the easier 1990 exam and the more difficult 1996 exam. No significant differences were found. While our results instill confidence that these changes have not impacted the NAEP trend line, our findings are both data-specific and limited in scope, and NAEP should carefully evaluate future adjustments to the test in this manner. 相似文献

This study examines the predictive validity of three commonly used nursing school admission indices, that is, scholastic aptitude test scores, matriculation grades, and evaluations of performance in a group interview situation, in a sample of 321 Israeli nursing school students. Grade point average, supervisor evaluation of clinical internship, and scores on a government certification exam served as primary indices of criterion performance. Whereas composite aptitude test scores correlated moder ately with both grade point average and certification exam scores, matriculation grades correlated negligibly with all three criterion measures. Group interview ratings correlated moderately with clinical performance, but negligibly with the remaining criteria. Aptitude test scores were not found to be biased predictors of criterion performance by ethnicity or social background. The implications of these findings for the selection of nursing school candidates in Israel are discussed. 相似文献
