Peer review: still king in the digital age          下载免费PDF全文

David NICHOLAS  Anthony WATKINSON  Hamid R. JAMALI  Eti HERMAN  Carol TENOPIR  Rachel VOLENTINE  Suzie ALLARD  Kenneth LEVINE 《Learned Publishing》2015,28(1):15-21

The article presents one of the main findings of an international study of 4,000 academic researchers that examined how trustworthiness is determined in the digital environment when it comes to scholarly reading, citing, and publishing. The study shows that peer review is still the most trustworthy characteristic of all. There is, though, a common perception that open access journals are not peer reviewed or do not have proper peer‐review systems. Researchers appear to have moved inexorably from a print‐based system to a digital system, but it has not significantly changed the way they decide what to trust. They do not trust social media. Only a minority – although significantly mostly young and early career researchers – thought that social media are anything other than more appropriate to personal interactions and peripheral to their professional/academic lives. There are other significant differences, according to the age of the researcher. Thus, in regard to choosing an outlet for publication of their work, young researchers are much less concerned with the fact that it is peer reviewed.  相似文献

Peer Group Norms and Accountability Moderate the Effect of School Norms on Children's Intergroup Attitudes          下载免费PDF全文

Luke McGuire  Adam Rutland  Drew Nesdale 《Child development》2015,86(4):1290-1297

The present study examined the interactive effects of school norms, peer norms, and accountability on children's intergroup attitudes. Participants (n = 229) aged 5–11 years, in a between‐subjects design, were randomly assigned to a peer group with an inclusion or exclusion norm, learned their school either had an inclusion norm or not, and were accountable to either their peer group, teachers, or nobody. Findings indicated, irrespective of age, that an inclusive school norm was less effective when the peer group had an exclusive norm and children were held accountable to their peers or teachers. These findings support social identity development theory (D. Nesdale, 2004, 2007), which expects both the in‐group peer and school norm to influence children's intergroup attitudes.  相似文献   

Parental perspectives and challenges in inclusive education in Singapore     

Meng Ee Wong  Kenneth K. Poon  Sarinajit Kaur  Zi Jia Ng 《Asia Pacific Journal of Education》2015,35(1):85-97

Relatively little work has focused on inclusive education in Singapore. This study examines the experiences and perceptions of parents whose children with disabilities are attending mainstream secondary schools in Singapore. Data was drawn from interviews with 13 parents of children with mild disabilities. Our findings reveal that parental perspective on inclusive education in Singapore is not only about classroom support but also reflects a deeper concern about whether their children with disabilities will emerge from school as contributing individuals in society. While parents strive to effectively include their children with disabilities in mainstream classrooms, there were dichotomies in their (1) understanding of disabilities, (2) expectations of school support, and (3) expectations for their child with disabilities. Given that academic and social prowess is a critical prerequisite to have a shot at entering the meritocratic Singapore society, the tension parents experience is to gauge a reasonable amount of pressure to exert on their children, the school and themselves as they assert their children's educational entitlements within an imperfect but evolving state of inclusion.  相似文献   

Revisiting Zhang’s scale of transactional distance: refinement and validation using structural equation modeling     

Ravi C. Paul  William Swart  Aixiu Monica Zhang  Kenneth R. MacLeod 《Distance Education》2015,36(3):364-382

Transactional distance has been defined as barriers to students’ engagement with learning in the online environment. This research updates Zhang’s (2003) scale of transactional distance, which quantified the extent of the barriers, in light of the massive changes in today’s web-based learning environment. The resulting revised scale of transactional distance (RSTD) is a parsimonious version with 12 elements (compared to 31 original) that measure the transactional distance between student and teacher, student and student, and student and content. The RSTD has excellent factorial validity and reliability, yields better fit statistics, and is easier and less time-consuming to apply. The transactional distance values are unique predictors of student satisfaction, which is correlated to learning and persistence (a major concern with massive open online courses). This information can form the basis for a systematic approach to improving the design of today’s contemporary open, flexible, distance education courses and thus serve as a valuable tool for researchers and educators alike.  相似文献   

Design-Based Research Within the Constraints of Practice: AlgebraByExample     

Julie L. Booth  Laura A. Cooper  Alexandra Huyghe  Kenneth R. Koedinger  E. Juliana Paré-Blagoev 《Journal of Education for Students Placed at Risk》2015,20(1-2):79-100

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.  相似文献   

A Classroom Exercise to Examine the Trade‐off between Mission Capacity and Life Cycle Cost          下载免费PDF全文

Keebom Kang  Kenneth H. Doerr 《Decision Sciences Journal of Innovative Education》2015,13(1):3-20

This article presents a classroom exercise, centered on a simulation that has been used for 4 years in an MBA program to help students develop an understanding of the trade‐offs involved in managing capital assets in the public sector. Though often ignored in business schools, mission is a key criterion that must be considered when managing such assets, and acts as a surrogate for profit. The case presents a rich environment in which the impact of cost reductions (or additional investments) on mission can be quantified, and trade‐offs can be assessed and discussed. It gives students a chance to develop creative ideas for process improvement, and provides sufficient data for them to analyze the impact of their suggestions in a rigorous way.  相似文献   

A defensive mindset: A pattern of social information processing that develops early and predicts life course outcomes     

Kenneth A. Dodge  Yu Bai  Jennifer Godwin  Jennifer E. Lansford  John E. Bates  Gregory S. Pettit  Damon Jones 《Child development》2022,93(4):e357-e378

The hypothesis was tested that some children develop a defensive mindset that subsumes individual social information processing (SIP) steps, grows from early experiences, and guides long-term outcomes. In Study 1 (Fast Track [FT]), 463 age-5 children (45% girls; 43% Black) were first assessed in 1991 and followed through age 32 (83% retention). In Study 2 (Child Development Project [CDP]), 585 age-5 children (48% girls, 17% Black) were first assessed in 1987 and followed through age 34 (78% retention). In both studies, measures were collected of early adverse experiences, defensive mindset and SIP, and adult outcomes. Across both studies, a robust latent construct of school-age defensive mindset was validated empirically (comparative fit index = .99 in each study) and found to mediate the impact of early child abuse (38% in FT and 29% in CDP of total effect) and peer social rejection (14% in FT and 7% in CDP of total effect) on adult incarceration.  相似文献
