The developmental interplay of academic self-concept and achievement within and across domains among primary school students     

《Contemporary educational psychology》2019

The reciprocal internal/external frame of reference model (RI/EM) extends the internal/external frame of reference model (I/EM) over time and the reciprocal effects model (REM) across domains. The RI/EM postulates positive developmental relations between academic achievement and self-concept within a domain and negative relations across two non-matching domains (e.g., math and English). However, until now, empirical investigations of the RI/EM had only focused on secondary school students from specific countries. In the present study, we test whether the RI/EM also applies to primary school students and to students in the United States, by using a representative longitudinal data set: the Early Childhood Longitudinal Study-Kindergarten (ECLS-K: 1998–1999). We found positive reciprocal relations between academic self-concept and standardized test scores within a domain, whereas the effect of prior achievement on self-concept was much stronger (skill-development part) than the effect of self-concept on achievement (self-enhancement). Furthermore, we found negative effects of achievement on subsequent self-concepts across domains (I/E frame of references). Overall, the findings of the study strongly support the RI/EM for primary school students. Our results are compared to previous findings in the literature for secondary school students and are discussed with regard to self-concept formation in primary school.  相似文献

Data Science Support at the Academic Library     

Jeffrey C. Oliver  Christine Kollen  Benjamin Hickson  Fernando Rios 《图书馆管理杂志》2019,59(3):241-257

Data science is a rapidly growing field with applications across all scientific domains. The demand for support in data science literacy is outpacing available resources at college campuses. The academic library is uniquely positioned to provide training and guidance in a number of areas relevant to data science. The University of Arizona Libraries has built a successful data science support program, focusing on computational literacy, geographic information systems, and reproducible science. Success of the program has largely been due to the strength of library personnel and strategic partnerships with units outside of the library. Academic libraries can support campus data science needs through professional development of current staff and recruitment of new personnel with expertise in data-intensive domains.  相似文献
