Mantel-Haenszel and SIBTEST, which have known difficulty in detecting non-unidirectional differential item functioning (DIF), have been adapted with some success for computerized adaptive testing (CAT). This study adapts logistic regression (LR) and the item-response-theory-likelihood-ratio test (IRT-LRT), capable of detecting both unidirectional and non-unidirectional DIF, to the CAT environment in which pretest items are assumed to be seeded in CATs but not used for trait estimation. The proposed adaptation methods were evaluated with simulated data under different sample size ratios and impact conditions in terms of Type I error, power, and specificity in identifying the form of DIF. The adapted LR and IRT-LRT procedures are more powerful than the CAT version of SIBTEST for non-unidirectional DIF detection. The good Type I error control provided by IRT-LRT under extremely unequal sample sizes and large impact is encouraging. Implications of these and other findings are discussed. 相似文献

The purpose of the current study was to examine dimensionality and concurrent validity evidence of the EARLI numeracy measures (DiPerna, Morgan, &; Lei, 2007), which were developed to assess key skills such as number identification, counting, and basic arithmetic. Two methods (NOHARM with approximate chi-square test and DIMTEST with DETECT classifications) were used to examine the dimensionality of each of the dichotomously scored measures. Both indicated unidimensionality for four of the EARLI measures (Counting Aloud, Counting Object, Measurement, and Pattern Recognition); however, results were discrepant for Numbers and Shapes. For the polytomously scored measure (Grouping), exploratory factor analysis indicated essential unidimensionality. In addition, the majority of the EARLI numeracy items did not appear to function differently by demographic variables, and scores from the EARLI numeracy measures demonstrated adequate concurrent relationships with scores from the WJ-III mathematics subtests. 相似文献

Structural equation modeling (SEM) is a versatile statistical modeling tool. Its estimation techniques, modeling capacities, and breadth of applications are expanding rapidly. This module introduces some common terminologies. General steps of SEM are discussed along with important considerations in each step. Simple examples are provided to illustrate some of the ideas for beginners. In addition, several popular specialized SEM software programs are briefly discussed with regard to their features and availability. The intent of this module is to focus on foundational issues to inform readers of the potentials as well as the limitations of SEM. Interested readers are encouraged to consult additional references for advanced model types and more application examples. 相似文献

In recent years, students’ test scores have been used to evaluate teachers’ performance. The assumption underlying this practice is that students’ test performance reflects teachers’ instruction. However, this assumption is generally not empirically tested. In this study, we examine the effect of teachers’ instruction on test performance at the item level using a hierarchical differential item functioning approach. The items are from the U.S. TIMSS 2011 4th-grade math test. Specifically, we tested whether students who had received instruction on a given item performed significantly better on that item compared with students who had not received such instruction when their overall math ability was controlled for, whether with or without controlling for student-level and class-level covariates. This study provides preliminary findings regarding why some items show instructional sensitivity and sheds light on how to develop instructionally sensitive items. Implications and directions for further research are also discussed. 相似文献

Based on different language systems and educational practices of their respective countries, hypotheses were made regarding how 15-year-old students from Shanghai-China and the US might differ in the 5 reading subskills designated in the Programme for International Student Assessment (PISA) when they have the same overall reading ability (i.e., when their overall reading ability is controlled for). A multilevel analysis was conducted to test the hypotheses using the PISA 2009 reading dataset. When we controlled for students' overall reading ability, individual socioeconomic status (SES), and school mean SES, Shanghai-Chinese students performed significantly better in integrating and interpreting than US students. Further, when we controlled for students' overall reading ability and school mean SES, US students showed significantly higher performance in reading non-continuous texts than Shanghai-Chinese students, whereas US students showed significantly lower performance in reading continuous texts. The results of this study can inform reading instruction and learning in the 2 countries. 相似文献
