The isolated elements and variability effects of cognitive load theory were used to alter the element interactivity of Chinese characters when instructing novice learners (72 overseas students at a Chinese university) in writing characters using worked examples-practice procedures. A group of characters with more than eight strokes was disassembled into three individual components. Students were required to trace examples and practice writing of either similar sequences of isolated components followed by integrated components of full characters (Isolated–Integrated sequences); variable sequences of isolated followed by integrated components (Variability–Integrated sequences); or conventional Integrated–Integrated sequences of full characters. It was hypothesized that the fully integrated stroke-movements form of example-practice sequences would result in less learning due to a greater cognitive load. The results demonstrated that the participants in both the Isolated–Integrated and Variable–Integrated groups performed significantly better than the Integrated–Integrated group with the Variable–Integrated group outperforming the Isolated–Integrated group. 相似文献

Factor analysis is a popular statistical technique for multivariate data analysis. Developments in the structural equation modeling framework have enabled the use of hybrid confirmatory/exploratory approaches in which factor-loading structures can be explored relatively flexibly within a confirmatory factor analysis (CFA) framework. Recently, Muthén & Asparouhov proposed a Bayesian structural equation modeling (BSEM) approach to explore the presence of cross loadings in CFA models. We show that the issue of determining factor-loading patterns may be formulated as a Bayesian variable selection problem in which Muthén and Asparouhov's approach can be regarded as a BSEM approach with ridge regression prior (BSEM-RP). We propose another Bayesian approach, denoted herein as the Bayesian structural equation modeling with spike-and-slab prior (BSEM-SSP), which serves as a one-stage alternative to the BSEM-RP. We review the theoretical advantages and disadvantages of both approaches and compare their empirical performance relative to two modification indices-based approaches and exploratory factor analysis with target rotation. A teacher stress scale data set is used to demonstrate our approach. 相似文献

While prior studies have focused on the effect of leader–member exchange (LMX), representing a dyadic differentiated exchange relationship between a leader and followers, on employees’ job-related outcomes, how LMX at the group level influences one’s life domain has been ignored. The present study shifted attention to the relationship between LMX mean and employee life satisfaction as well as the boundary conditions. Using a sample of 471 employees from 53 groups and hierarchical linear modeling, we examined the cross-level main effect of LMX mean on life satisfaction and the moderation of group power distance and individual political skill. The results revealed that LMX mean had a work-to-life spillover effect on employee life satisfaction. Employee political skill positively moderated the relationship between LMX mean and life satisfaction, whereas group power distance negatively moderated the relation. Theoretical and practical implications were further discussed. 相似文献
