基于计算机的测验已逐渐普及,但不同的计算机测验形式在测量相同任务时可能会产生测验结果的偏差,从而导致教育测量与评价结果的不公平性。文章基于项目反应理论,探讨了计算机化线性测验与计算机自适应测验在测验效率、测验结果的统计学特征及其对考生个体心理特质的影响是否等效等问题,并以师范生"现代教育技术"课程为例开展了实证研究,结果显示:两种测验中考生的分数具有可比性,计算机自适应测验具有更高的测验效率与测验信度,但有无即时反馈对考生测验焦虑的影响较大;而计算机化线性测验具有更合理的内容效度,有无即时反馈对考生测验焦虑的影响较小。文章的研究不仅对教学评价中测验形式的选择是否公平合理进行了科学分析,而且为施测者根据测验场景有针对性地选择测验形式提供了理论参考。 相似文献

一、自适应试题库系统的理论依据: 一个良好的测试系统必须以明确的教育测量理论作为理论基础。自适应测验是以近年来在网络教育领域中兴起的项目反应理论(IRT item response theory)为基础,强调测验应该自动地适应被试者的具体情况,将试题的内容、数量、难度和知识分布等因素与被试者的情况综合统筹,以受测者的回答问题的情况,经题目特征函数的运算,推测受测者的能力。流行的经典测试理论(CTT classical test theoryr)是目前教学中最常见的测试手段,适合横向的常模参照测验,支持固定试题的测验方法。基于这两种理论,该系统以自适应测验为 相似文献

This study focused on the effects of administration mode (computer-adaptive test [CAT] versus self-adaptive test [SAT]), item-by-item answer feedback (present versus absent), and test anxiety on results obtained from computerized vocabulary tests. Examinees were assigned at random to four testing conditions (CAT with feedback, CAT without feedback, SAT with feedback, SAT without feedback). Examinees completed the Test Anxiety Inventory (Spielberger, 1980) before taking their assigned computerized tests. Results showed that the CATs were more reliable and took less time to complete than the SATs. Administration time for both the CATs and SATs was shorter when feedback was provided than when it was not, and this difference was most pronounced for examinees at medium to high levels of test anxiety. These results replicate prior findings regarding the precision and administrative efficiency of CATs and SATs but point to new possible benefits of including answer feedback on such tests. 相似文献

The overlap of words specifically taught in reading textbooks with the contents of standardized reading achievement tests may be a source of bias that is frequently overlooked in psychoeducational assessments. This study compares the standardized achievement test performance of 62 second graders receiving instruction in two different reading curricula (Open Court and Houghton-Mifflin) to determine whether either curriculum generates different quantitative estimates of reading achievement. Reading subtest scores derived from the Kaufman Test of Educational Achievement-Brief Form (K-TEA), the Wide Range Achievement Test-Revised (WRAT-R), and the Reading Recognition and Reading Comprehension subtests from the Peabody Individual Achievement Test (PIAT) were examined. Grade level equivalents and scaled scores from the California Achievement Test (CAT) were also examined. Three Curriculum × Test repeated measures ANOVAs were conducted using grade level scores (2×7), standard scores (2×4), and CAT scaled scores (2 × 5) as dependent measures. A significant Curriculum × Test interaction was identified, suggesting differences among tests in estimates of reading ability as a function of the reading program. 相似文献

When a computerized adaptive testing (CAT) version of a test co-exists with its paper-and-pencil (P&P) version, it is important for scores from the CAT version to be comparable to scores from its P&P version. The CAT version may require multiple item pools for test security reasons, and CAT scores based on alternate pools also need to be comparable to each other. In this paper, we review research literature on CAT comparability issues and synthesize issues specific to these two settings. A framework of criteria for evaluating comparability was developed that contains the following three categories of criteria: validity criterion, psychometric property/reliability criterion, and statistical assumption/test administration condition criterion. Methods for evaluating comparability under these criteria as well as various algorithms for improving comparability are described and discussed. Focusing on the psychometric property/reliability criterion, an example using an item pool of ACT Assessment Mathematics items is provided to demonstrate a process for developing comparable CAT versions and for evaluating comparability. This example illustrates how simulations can be used to improve comparability at the early stages of the development of a CAT. The effects of different specifications of practical constraints, such as content balancing and item exposure rate control, and the effects of using alternate item pools are examined. One interesting finding from this study is that a large part of incomparability may be due to the change from number-correct score-based scoring to IRT ability estimation-based scoring. In addition, changes in components of a CAT, such as exposure rate control, content balancing, test length, and item pool size were found to result in different levels of comparability in test scores. 相似文献

Memory and Processing Speed in Preterm Children at Eleven Years: A Comparison with Full-Terms 总被引：5，自引：0，他引：5
This study examined the effects of prematurity on 11-year-olds' performance on 2 specific aspects of cognition—memory and processing speed, using a new computer-administered battery, the Cognitive Abilities Test (CAT: Detterman). Preterms performed more poorly than their full-term controls on all memory tasks; this relative deficit was associated with the presence and severity of neonatal Respiratory Distress Syndrome (RDS). Preterms were also slower on selected aspects of processing speed but not on motor speed. Memory and processing speed, taken together, accounted for much of the 10-point difference in WISC-R IQ between groups. 相似文献

This paper includes an overview of curriculum information and the basic techniques of a multisensory approach for teaching
alphabet and dictionary skills, reading, spelling, and cursive handwriting. It also reports the results of a four-year study
of reading and spelling in both remedial and nonremedial classes in a public school. The California Achievement Test (CAT)
scores in reading and spelling for students in both remedial and nonremedial classes improved over baseline scores following
this multisensory approach. Additionally, there was a tendency for the CAT mean scores to increase corresponding to the number
of years students had been taught by the multisensory program. 相似文献

This article describes a longitudinal analysis of a nationally representative cohort of over 80,000 pupils in England who completed both national end of Key Stage 2 (KS2) tests and the Cognitive Abilities Test (CAT) at age 11 in 1997, national end of Key Stage 3 (KS3) tests at age 14 in summer 2000 and General Certificate of Secondary Education (GCSE) and other public examinations at age 16 in summer 2002. The CAT had significantly higher correlations with subsequent KS3 and GCSE outcomes than did KS2 test points scores. However, multiple regression analyses indicated that a combination of CAT and KS2 test scores gave the best prediction of future KS3\GCSE outcomes. The article argues that measures of both pupils' general transferable learning abilities, and measures of specific curricular attainments at the end of primary school have unique and distinct value at the start of the secondary phase. The article discusses some practical ways in which the different types of assessment data can be used within the secondary school. 相似文献
