We report preliminary behaviour genetic analyses of reading and listening comprehension from The Colorado Learning Disabilities Research Center. Although the twin sample with these new measures is still of limited size, we find substantial, and significant, genetic influences on individual differences in both reading and listening comprehension. In addition, word recognition and listening comprehension each accounted for significant independent genetic influences on reading comprehension. Together, they accounted for all the genetic influence on reading comprehension, indicating a largely genetic basis for the ‘simple model’ of individual differences in reading comprehension proposed by Hoover and Gough (1990) . 相似文献

Research in the United States suggests that teachers view Black students' misbehavior as more likely to reoccur, but such research has not disentangled the effect of race from related factors. We used conjoint analysis to experimentally test the effect of multiple student characteristics on the chances of being referred for a behavior intervention program. Although preservice teacher participants were not more likely to refer Black students, they were more likely to refer students who had lower grades, lived in poverty, lived with a single mother, and had been retained. We interpret these results and highlight directions for future research and practice. 相似文献

Using Differential Item Functioning Procedures to Explore Sources of Item Difficulty and Group Performance Characteristics 总被引:1,自引:0,他引:1
Statistics used to detect differential item functioning can also reflect differential strengths and weaknesses in the performance characteristics of population subgroups. In turn, item features associated with the differential performance patterns are likely to reflect some facet of the item task and hence its difficulty, that might previously have been overlooked. In this study, several item features were identified and coded for a large number of reading comprehension items from the two admissions testing programs. Item features included subject matter content, various properties of item structure, cognitive demand indicators, and semantic content (propositional analysis). Differential item functioning was evaluated for males and females and for White and Black examinees. Results showed a number of significant relationships between item features and indicators of differential item functioning—many of which were consistent across testing programs. Implications of the results for related areas of research are discussed. 相似文献

This research uses a conceptual model to examine the influence of a change in accreditation standards on a representative
national sample of 203 engineering programs at 40 institutions. Based on data collected from more than 140 program chairs,
1,200 faculty, 4,300 graduates of 2004, and 5,400 graduates of 1994, the study investigates the differential impact of the
change in accreditation standards on programs reviewed in different years during the period of transition. Despite significant
variation across most of the measures and groups in 1994 (before the introduction of the new accreditation criteria), the
2004 evidence demonstrates a surprisingly uniform level of student experiences and outcomes. These findings suggest that engineering
accreditation is beginning to accomplish its quality assurance goals.
