Homeschool background,time use and academic performance at a private religious college     

Daniel L. Bennett  Elyssa Edwards  Courtney Ngai 《Educational studies》2019,45(3):305-325

We study the effects of homeschool background and time use on academic performance among students at Patrick Henry College, a private religious institution with a 63-credit core classical liberal arts curriculum. Using ordinary least squares regression analysis, we examine four research questions: (1) Does time use influence academic performance? (2) Do homeschooled students perform differently than traditionally schooled students? (3) Does parental education moderate the impact of homeschooling on academic performance? (4) Does homeschooling moderate the impact of ACT scores on academic performance?  相似文献   

Longitudinal analyses of educational outcomes for youth transitioning out of care in the US: trends and influential factors     

Nathanael Okpych  Mark Courtney 《牛津教育评论》2019,45(4):461-480

ABSTRACT

This paper draws on data collected from two of the most extensive longitudinal studies of care leavers in the US. The Midwest Study (2003–2011) included 732 youths in foster care in three Midwestern states, and the CalYOUTH Study (2012–present) includes 727 youths in California foster care. The paper has three objectives: (1) describe trends in secondary and postsecondary educational attainment at different ages; (2) summarise findings on predictors of educational attainment; and (3) summarise findings on the impact of extended foster care (EFC) on educational attainment. Results from these two studies show that by age 21, 77–85% of care leavers finish a secondary credential and 31–52% enrol in college. By age 25, about 8% have earned a college degree. Results from multivariate analyses find that youths’ educational background and parental status were consistently associated with later educational attainment. Specific aspects of social support also influenced college outcomes. Life demands after enrolling in college (e.g. employment, parenthood) played a more influential role in college degree attainment than did aspects of youths’ background. Characteristics of colleges also predicted youths’ odds of degree completion. Finally, existing evidence suggests that EFC promotes secondary credential completion and college entry, but not college persistence or degree completion.  相似文献

Verbal self-instructional training: An examination of its efficacy, maintenance, and generalisation     

Sudhakar Rath 《European Journal of Psychology of Education - EJPE》1998,13(3):399-409

The study examined the differential efficacy, maintenance and generalisation effects of verbal self-instructional (VSI) training on reading disabled children. Type of sub-culture (Tribal Vs. Non-tribal) is crossed with type of cognitive stage (concrete Vs. formal operation) to produce four training groups with 15 subjects per cell. The subjects were trained for 10 weeks and retested for post-test and follow-up data. While VSI training was beneficial to non-tribals and children of formal operational stage, it failed in case of tribals and children of concrete operational stage. VSI effects were maintained over four months time and evidenced clear generalisation effects.  相似文献

The role of online communities of practice in promoting sociotechnical capital among science teachers     

Rita Karam  Susan G. Straus  Albert Byers  Courtney A. Kase  Matthew Cefalu 《Educational technology research and development : ETR & D》2018,66(2):215-245

This study explores the diffusion of Web 2.0 technologies among science educators and the ways that these technologies are used to build teacher professional communities of practice (CoP) in life sciences and physical sciences. We used surveys and web analytics collected over a 21-month period to examine factors that motivate teachers to collaborate in these CoPs and the extent to which collaborative participation contributes to the development of sociotechnical capital and job outcomes, such as instructional practices and self-efficacy for science instruction. Results showed that only the lack of co-located peers at teachers’ schools predicted CoP participation. Participation did not predict job outcomes, but it did predict some aspects of sociotechnical capital, such as a cohesive climate and situated knowledge. In addition, sociotechnical capital was associated with job outcomes, including use of inquiry-based instruction, use of inquiry-based classroom activities and teacher self-efficacy. The lack of effect of most of the antecedent variables in predicting participation and the relatively minor role of participation in contributing to sociotechnical capital and job outcomes may be explained by floor effects on participation due to infrequent and ephemeral engagement of CoP members. Although participation rates were generally low, the positive association of participation with sociotechnical capital as well as generally favorable ratings of sociotechnical constructs suggest that online CoPs may have value for distributed science educators. Future research should address whether persistent participation by individuals is needed to build and sustain sociotechnical capital in online CoPs and to enhance development of participants’ teaching attitudes/practices.  相似文献   

Using electronic communication to bridge the research to practice gap among mentoring professionals     

Cindy Ann Smith  Lara Willox  Courtney Olds 《Mentoring & Tutoring: Partnership in Learning》2017,25(3):369-390

The field of mentoring includes a broad base of stakeholders, such as researchers and practitioners who implement mentoring programs. The research-to-practice gap is an ongoing area of concern in many fields of social science including mentoring. One reason for this is that researchers and practitioners often operate in isolation. Technology is playing an ever-increasing role in the professional lives of practitioners and researchers, therefore, this study explored the engagement of both groups through the YOUTHMENTORING list serve; a resource provided by the University of Illinois-Chicago. Through a comprehensive qualitative study of list serve content, connections, and engagement it was found that the YOUTHMENTORING list serve promoted collaboration among stakeholders. Members found the resource to be valuable to their practice. Implications for the field and future research are discussed.  相似文献   

EVALUATION OF A TRUANCY DIVERSION PROGRAM AT NINE AT‐RISK MIDDLE SCHOOLS     

Courtney M. Haight  Gillian V. Chapman  Marisa Hendron  Rachel Loftis  Christopher A. Kearney 《Psychology in the schools》2014,51(7):779-787

Many schools are faced with the prospect of soaring absenteeism rates, despite the use of traditional truancy courts and other legal interventions. A recent trend in the literature has been to explore alternative, hybrid, and multidisciplinary approaches to address the underlying obstacles to school attendance. These programs are often integrated into schools to reduce stigma and transportation burdens on families. The present study involved an evaluation of a truancy diversion program in nine at‐risk middle schools in an ethnically diverse sample. Graduates from the program demonstrated significant declines in internalizing and externalizing behavior problems. In addition, participants and their parents expressed high levels of perceived improvement in academic performance. Academic tutoring was found to differentiate program graduates from nongraduates. Results are preliminary but discussed within the context of the role of school attachment in truancy diversion programs.  相似文献
