Explaining the substantial inter-domain and over-time correlations in student achievement: the importance of stable student attributes

Multi-domain and longitudinal studies of student achievement routinely find moderate to strong correlations across achievement domains and even stronger within-domain correlations over time. The purpose of this study is to examine the sources of these patterns analysing student achievement in 5 domains across Years 3, 5 and 7. The analysis is of longitudinal population data of over 22,000 students and utilizes fixed-effects models to incorporate stable general and domain-specific latent factors. These latent factors correspond to a general cognitive-ability-like factor and specific aptitudes in particular, or types of, subject areas. The preferred model incorporates both general and domain-specific latent factors with stronger effects for the general factor, although the domain-specific factors are particularly strong for spelling and numeracy. When taking into account general and domain-specific latent factors, the effects of student’s socioeconomic status (SES) and school SES are trivial.

Do digital natives differ by computer self-efficacy and experience? An empirical study

This study serves to validate a Chinese translation of the Digital Native Assessment Scale (C-DNAS) and assess if significant differences exist between a sample of students and teachers from a culture different than the one used in the development of the DNAS. Participants were 402 university students from one province in Mainland China. Results of the confirmatory factor analysis revealed that the C-DNAS possessed a stable factorial structure and was a valid measure among Chinese-speaking participants in Mainland China. Tests of measurement invariance revealed score equivalence among the students for each of the four factors of the C-DNAS: grew up with technology; comfortable with multitasking; reliant on graphics for communication; and thrive on instant gratifications and rewards, by computer self-efficacy and experience. Finally, tests of latent mean differences revealed significant differences in each of the four factors by computer experience but not by computer self-efficacy. Implications for research are discussed.     

谈多重复句分析

多重复句分析主要包括两个方面内容 :一是结构层次的确定 ,二是逻辑关系的把握。无论哪一方面的分析 ,都应有规律可寻。抓住关联词语是解决问题的有效途径 ,看划开之后各部分是否具有相对完整性和换位后能否成立是检查层次划分正确与否的有效手段。     

科学哲学及其实在论本质的先验分析

科学哲学以及相关的自然科学在本质上是关于实在的知识。但这一结论本身只有在先验的视域中才能显示出清晰的含义,一般关于实在论的讨论也只有在先验视域中才能有逻辑的结果。然而在这一视域中的考察也表明,科学哲学的“超验性”问题又是与其实在本质直接相关的,先验哲学在研究其发生发展规律的同时又承认这一点。整个20世纪科学哲学进程都表明了一个科学的经验实在（论）的性质,同时这一进程也证实了先验哲学关于先天知识（先验逻辑）的普遍有效性的论述。
