A standardized tool for assessing the quality of classroom-based shared reading: Systematic Assessment of Book Reading (SABR)

Participation in shared-reading experiences is associated with children's language and literacy outcomes, yet few standardized assessments of shared-reading quality exist. The purpose of this study was to describe the psychometric characteristics of the Systematic Assessment of Book Reading (SABR), an observational tool designed to characterize the quality of classroom-based shared-reading sessions in early childhood settings. Participants included 105 preschool teachers. The quality of teachers’ videotaped, whole-class shared-reading sessions was examined using the SABR. Reliability levels for each of the SABRs five constructs were examined, as well as delayed alternate-form reliability and inter-rater reliability. The tools’ factor structure and construct validity were also assessed. Findings provide initial validation and preliminary evidence that the SABR is a reliable and valid tool. Potential uses for early childhood researchers, teachers, and allied professionals are described.

论市场经济中的企业社会责任伦理

企业的社会责任伦理包括经济责任伦理、法律责任伦理和环境责任伦理三个方面。企业是“经济人”和“道德人”的统一,具有经济和伦理的“双重人格”,因此必须对企业的经济活动进行伦理评价。企业承担法律责任,是市场经济发展的内在要求。法律属于制度范畴,具有他律性和效益性。企业要把履行法律责任的行为上升到法律道德意识的高度去认识,变法律的他律为道德自律。对环保的态度已成为衡量当代人类道德水平的试金石,也是企业不可推卸的社会责任。

MODELS OF EVALUATION AND THEIR RELATION TO STUDENT CHARACTERISTICS

The union and disjunction models for combining individual test marks to yield final grade distributions were outlined. It was expected that these models would differentially favor students according to their characteristic methods of learning and studying. The models were examined empirically in two educational psychology classes; five performance assessments were available, as well as eleven dimensions of study behavior and academic attitudes. While there was a substantial correlation between the distributions derived from the two models, they were found significantly to favor different student characteristics. The union model, relative to the disjunction model, favored students who were dependent, who interrelated different aspects of their course work, who scheduled their work and who rote-learned material. These differences were interpreted in terms of the educational assumptions underlying the two models. Some implications of the study for grading practice were suggested.

A causal model of students' achievement in a college physics course

To explain students' achievement in the mechanics segment of a college physics course, a causal model is proposed whose variables are the three constructs: Newtonian physics, math ability, and science experience. Each variable specifies several variates, whose numerical values were measured and intercorrelations computed. The Factorial Modeling (FaM) procedure is applied to the data to estimate the coefficients of the proposed model's structural equations. The FaM results indicate that the model is plausible and that its first two variables account for approximately 34% of the variance in the criterion variate, students' mechanics achievement. The implications of the findings for physics instruction are discussed.     

EPR-RCGA-based modelling of compression index and RMSE-AIC-BIC-based model selection for Chinese marine clays and their engineering application

The compression index is a key parameter in the field of soft clay engineering. In this paper, we propose an improved method for correlating the compression index with the physical properties of intact Chinese marine clays that are involved in many construction projects in coastal regions in China. First, the compression index and some common physical properties of clays from 21 regions along the Chinese coast are extracted from the literature. Then, a basic regression analysis for the compression index using the natural water content and Atterberg limits is conducted. To improve the correlation performance, an evolutionary polynomial regression (EPR) and real coded genetic algorithm (RCGA) combined technique is adopted to formulate different equations involving different numbers of variables. An optimal correlation using only natural water content and liquid limit as input parameters is finally selected according to the root mean square error (RMSE), Akaike’s information criterion (AIC), and Bayesian information criterion (BIC). The proposed correlation is evaluated and shown to perform better than existing empirical correlations in predicting the compression index for all selected Chinese marine clays. This correlation is validated to be reliable and applicable to engineering applications through the prediction of the properties of an embankment on the southeast coast of China using finite element method. All comparisons show that the EPR and RCGA combined technique is powerful for correlating the compression index with the physical properties of the clay, and that model selection by RMSE, AIC, and BIC is effective. The proposed correlation could be used to update current formulations, and is applicable to engineering design in coastal regions of China.
