Retest effects in matrix test performance: Differential impact of predictors at different hierarchy levels in an educational setting     

Philipp Alexander Freund  Heinz Holling 《Learning and individual differences》2011,21(5):597-601

If tests of cognitive ability are repeatedly taken, test scores rise. Such retest effects have been observed for a long time and for a variety of tasks. This study investigates retest effects on figural matrix items in an educational context. A short term effect is assumed for the direct retest administration in the same test session, and a long term effect is assumed for a retest interval of six months. Using multilevel modeling, we analyze if the magnitude of these effects is not only influenced by individual variation, but also by the cluster structure of students grouped within classrooms. We also investigate if the use of identical versus parallel tests has an impact on the size of the retest effects. Our main results show a negligible short term retest effect, but a large long term retest effect. Using parallel tests does not contribute to understanding individual differences in retest effects. The variation in retest effects is larger between classrooms than between students. Reasoning ability, as measured with a different test, and school grades significantly influences retest effects at the individual level, but at the classroom level, only reasoning ability is a significant predictor.  相似文献

Studies on parallel seismic testing for integrity of cemented soil columns     

HUANG Da-zhi CHEN Long-zhu 《浙江大学学报(A卷英文版)》2007,8(11):1746-1753

The principle and process of parallel seismic (PS) testing for the integrity testing of cemented soil columns are in- troduced in this paper. A three-dimensional (3D) finite element model (FEM) for the pile-soil system is established for impulse responses. Under saturated soil or unsaturated soil condition, several vibrating velocity-time histories at different depths in parallel hole are obtained based on the numerical simulation. It shows that the length of the pile and the one-dimensional (1D) P-wave velocity in the pile can be determined easily from the features of the mentioned velocity-time histories. By examining the slopes of the first arrival time plotted versus depth or the depth where the amplitude of the first arrival significantly decreases, the length of the pile can be determined. The effects of the 3D P-wave propagation through the saturated soil and the defect of the cemented soil column on the velocity-time histories are also investigated.  相似文献

Modeling the Effects of Processing Effort and Ability in Response to Persuasive Message Arguments     

Christopher J. Carpenter  Franklin J. Boster 《Communication quarterly》2013,61(4):413-430

This study proposed a path model of the effects of message comprehensibility on attitude change with the measured cognitive mediators suggested by dual-process models of persuasion. An experiment was conducted using a 2 (strong arguments vs. weak arguments) × 2 (easy vs. difficult to understand arguments) fully crossed independent-groups design with 120 participants. The data were consistent with the traditional impact of message comprehensibility on difficulty of processing the message such that the effect of argument strength was diminished when the arguments were difficult, rather than easy, to understand. The path models were not consistent with the data, and the model was revised to produce adequate fit.  相似文献
