Rural adolescents' reading motivation,achievement and behavior across transition to high school     

Susan Chambers Cantrell  Margaret Rintamaa  Eric M. Anderman  Lynley H. Anderman 《The Journal of educational research》2018,111(4):417-428

The authors examined 1,781 rural students' reading motivation and behavior across the transition from middle to high school. Using expectancy-value theory, they investigated how motivational variables predicted changes in reading behavior and achievement across the transition in terms of their expectancies, values, and out-of-school reading behaviors. A repeated measures analysis of variance indicated significant increases in vocabulary, intrinsic value, and out-of-school reading, whereas significant decreases were found in attainment value. Hierarchical regression analysis indicated students' subjective expectancy for success was a significant predictor of increases in both comprehension and vocabulary scores. Students' utility value interacted with intrinsic value in predicting reading comprehension scores. In terms of change in students' reading behavior, their perceptions of intrinsic value and utility value were significant predictors. Gender interacted significantly with expectancies in predicting behaviors. Findings have implications for instructional support, particularly as it relates to reading motivation across the transition from middle to high school.  相似文献   

The Role of Heads of Department in the Professional Development of Educators: A Distributed Leadership Perspective     

André du Plessis  Eric Eberlein 《Africa Education Review》2018,15(1):1-19

The qualitative study reported on was, undertaken from a distributed leadership perspective, and was an attempt to provide understanding of how heads of department (HoDs) develop educators within the organisational context of different schools and subject departments. The findings are related to the current policy framework for professional development in South African schools. Two fee-paying and two non-fee-paying schools were selected and interviews were conducted with HoDs from single subject (unitary) and multi-subject (federal or confederate) departments in each school. The data was transcribed, coded, analysed and related to the research question. The findings confirmed that HoDs are a key link between principals and the educators in their classrooms. This supports the view that HoDs have formal responsibilities and accountabilities and they wield a horizontal and a vertical influence. Recommendations are made to improve professional development practice by HoDs in particular and in the education system in general.  相似文献   

Transfers of user process innovations to process equipment producers: A study of Dutch high-tech firms     

Jeroen P.J. de Jong  Eric von Hippel 《Research Policy》2009,38(7):1181-1191

A detailed survey of 498 high technology small and medium-sized enterprises in the Netherlands shows process innovation by user firms to be common practice. Fifty-four percent of these firms reported developing entirely novel process equipment or software for their own use and/or modifying these, both at significant private expense. Twenty-five percent of the user innovations in our sample were transferred to commercializing producer firms. Many transfers were made without any direct compensation. Very importantly from the perspective of effective diffusion of user innovations, innovations with higher commercial potential - and more general appeal for users - are much more likely to be transferred to producers. The pattern we document of frequent innovation by individual user firms at substantial cost, followed in many cases by voluntary, no-charge information spillovers to producers, suggests that “open source economics” may be a general pattern in the economy.  相似文献   

“Pyramiding: Efficient search for rare subjects”     

Eric von Hippel  Nikolaus Franke 《Research Policy》2009,38(9):1397-1406

The need to economically identify rare subjects within large, poorly mapped search spaces is a frequently encountered problem for social scientists and managers. It is notoriously difficult, for example, to identify “the best new CEO for our company,” or the “best three lead users to participate in our product development project.” Mass screening of entire populations or samples becomes steadily more expensive as the number of acceptable solutions within the search space becomes rarer.The search strategy of “pyramiding” is a potential solution to this problem under many conditions. Pyramiding is a search process based upon the idea that people with a strong interest in a topic or field tend to know people more expert than themselves. In this paper we report upon four experiments empirically exploring the efficiency of pyramiding searches relative to mass screening. We find that pyramiding on average identified the most expert individual in a group on a specific topic with only 28.4% of the group interviewed - a great efficiency gain relative to mass screening. Further, pyramiding identified one of the top 3 experts in a population after interviewing only 15.9% of the group on average. We discuss conditions under which the pyramiding search method is likely to be efficient relative to screening.  相似文献   

Rounding the Regression     

Eric Marland  Michael J. Bossé  Gregory Rhoads 《PRIMUS》2018,28(3):187-205

Rounding is a necessary step in many mathematical processes. We are taught early in our education about significant figures and how to properly round a number. So when we are given a data set and asked to find a regression line, we are inclined to offer the line with rounded coefficients to reflect our model. However, the effects are not as insignificant as they might seem at first. In this paper, we investigate some consequences of rounding the coefficients in a least squares linear regression with respect to the calculated value of R², and consider ways to minimize the amount of error that can arise.  相似文献   

Trial and Error: How Student Affairs Staff in Community Colleges Learn to Supervise     

Christina Lamb  Joseph Uong  Eric Coley  Lynne Valdes  Douglas Wendel 《Community College Journal of Research & Practice》2018,42(10):740-743

Supervisory skills play an important role in individual staff development and the achievement of organizational objectives. These skills are vital to professionals in community college student affairs, who support a diverse student population and a wide array of programming. This study was conducted to describe the kind of supervisory training experience student affairs professionals received. Through interviews with community college student affairs professionals, we found that many experienced a lack of formal training and acquired supervisory skills over time on the job, through trial and error, and from workshops.  相似文献   

Fulfilling the Transfer Mission at an Urban Technical College: How a Transfer Center Mediates Baccalaureate Aspirations for Students     

Eric R. Felix  Adrián Trinidad 《Community College Journal of Research & Practice》2018,42(12):861-877

This article examines transfer center practices at a historically vocational community college to understand how transfer to four-year institutions happens. By focusing on the transfer center, this study explores the practices that could support transfer goals in a vocational and technical environment. Drawing on concepts of organizational culture, we framed the ‘invisible’ factors that impact transfer practices and outcomes. An ethnographic case study approach was used to gather over 70 hours of observations and interviews with staff, faculty, and senior administration. This data were analyzed to assess how transfer practices supporting baccalaureate-aspiring students were shaped by a vocationally dominant environment. The experiences and practices of those responsible for the transfer center are highlighted. Results indicate that the culture of trades at the campus constrained the transfer resources available to the center, which led to an adaptation of trade-oriented practices by center staff, and ultimately, an attempt to preserve the transfer purpose for those seeking four-year institution. This study contributes to a paucity of research that examines transfer in historically technical community colleges, particularly in a transfer center setting.  相似文献

External load training does not alter balance performance in well-trained women     

Jeffrey D. Simpson  Brandon L. Miller  Eric K. O’Neal  Harish Chander  Adam C. Knight 《Sports biomechanics / International Society of Biomechanics in Sports》2018,17(3):336-349

This study investigated the influence of external load training (ELT) on static and dynamic balance. Nineteen females stratified into two groups (ELT = 9, control = 10) completed three testing sessions over 6 weeks. The ELT group wore weighted vests (WV) of ~8% body mass for 32 h/week during daily living and three training sessions/week for 3 weeks. Following completion of ELT, a 3 week detraining (DET) phase was completed. Bilateral and unilateral static balance were assessed with eyes open and closed. Dynamic balance was assessed using the star excursion balance test (SEBT). Static and dynamic balance variables were analysed using a 2 (group) x 3 (time) between participants repeated measures ANOVA (p < 0.05). Results revealed significant reductions in average centre of pressure (COP) velocity in the control group on the non-dominant limb with eyes closed, and significantly greater reach distances in the ELT group on the SEBT for the posteromedial and medial directions on the dominant limb (p < 0.05). These findings suggest the ELT group did not significantly improve their balance in comparison to the control group. However, future research should further examine this unique, supplemental training method and the impact on balance performance.  相似文献
