We studied the effects of academic performance, motivation, and social connectedness on third-year retention, transfer, and dropout behavior. To accommodate the three outcome categories and nesting of data within institutions, we fit a hierarchical multinomial logistic regression path model with first-year academic performance as a mediating effect. Our sample included 6,872 students representing 23 four-year universities and colleges. This work expands the current state of persistence research by (1) considering the effects of motivation and social connectedness on college persistence beyond the first year of college, (2) testing whether the effects of motivation and social connectedness on third-year retention and transfer are direct, indirect, or both, and (3) testing whether the effects of academic performance, motivation, and social connectedness are different for retention and transfer. We found that academic performance has large effects on likelihood of retention and transfer; academic self-discipline, pre-college academic performance, and pre-college educational development have indirect effects on retention and transfer; and college commitment and social connectedness have direct effects on retention. Academic self-discipline led to greater first-year academic performance, which suppressed its effect on retention and transfer. Practical and theoretical implications of these findings and directions for future research are discussed. A previous version of this paper was presented at the 2nd Annual National Symposium on Student Retention, Albuquerque, New Mexico, October 2006.  相似文献

Science Created by You (SCY) learning environments are computer-based environments in which students learn about science topics in the context of addressing a socio-scientific problem. Along their way to a solution for this problem students produce many types of intermediate products or learning objects. SCY learning environments center the entire learning process around creating, sharing, discussing, and re-using these learning objects. This instructional approach requires dedicated instructional designs, which are supplied in the form of what are called pedagogical scenarios. A SCY pedagogical scenario presents the learning process as an organized assembly of elementary learning processes, each associated with a specific learning object and a tool for creating this learning object. Designing a SCY learning environment is basically a two-step procedure: the first step is to select one of the available scenarios, and the second step is to define the domain content. The SCY technical infrastructure then handles the instantiation of the scenario as a SCY computer-based learning environment. In this article we describe the SCY pedagogical design scenarios and report on our experiences in designing four different SCY learning environments.  相似文献

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only.  相似文献
