Quality and relevance of domain-specific search: A case study in mental health     

Thanh Tin Tang  Nick Craswell  David Hawking  Kathy Griffiths  Helen Christensen 《Information Retrieval》2006,9(2):207-225

When searching for health information, results quality can be judged against available scientific evidence: Do search engines return advice consistent with evidence based medicine? We compared the performance of domain-specific health and depression search engines against a general-purpose engine (Google) on both relevance of results and quality of advice. Over 101 queries, to which the term ‘depression’ was added if not already present, Google returned more relevant results than those of the domain-specific engines. However, over the 50 treatment-related queries, Google returned 70 pages recommending for or against a well studied treatment, of which 19 strongly disagreed with the scientific evidence. A domain-specific index of 4 sites selected by domain experts was only wrong in 5 of 50 recommendations. Analysis suggests a tension between relevance and quality. Indexing more pages can give a greater number of relevant results, but selective inclusion can give better quality.  相似文献   

Collaborative Development and Evaluation of an Online Nursing Course     

Judith W. Alexander  Vera Polyakova-Norwood  Linda W. Johnston  Patricia Christensen  Renatta S. Loquist 《Distance Education》2003,24(1):41-56

Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.  相似文献   

Using stakeholder feedback to improve online professional development opportunities

Abstract

Traditional professional development is often characterized as being expensive, time consuming, and lacking impact. In contrast, online professional development provides greater flexibility and is becoming increasingly popular for school personnel. In this article, we report the process and outcomes of gathering feedback to adapt traditional in-person to online training differentiated for the participants to maximize utility, efficiency, and effectiveness in meeting the needs of key stakeholders. Focus groups were conducted with teachers, administrators, and other specialists to gather feedback on content as well as how online learning modules (OLMs) could be tailored to meet specific school site and team needs. We discuss our findings in the context of continuing efforts to improve general and specific professional development opportunities.  相似文献   

Strategies for Achieving Gender Equality in Higher Education and Research in Norway     

Ann S⊘yland  Anne-Marit Skarsb⊘  Nina Amble  Lise Christensen  Anna Ølnes 《Higher Education in Europe》2000,25(2):147-153

The vision behind the work of the gender equality advisors in Norwegian universities and the Research Council of Norway is that of full equality between women and men in all areas and at all levels of the sector of higher education. The Network of Gender Equality Advisors in Higher Education and Research was formed in 1994. Both good and less good news can be reported on the work accomplished so far. A double strategy is applied to tackle gender inequality: mainstreaming and special commitment.  相似文献   

Physical activity,physiological, and psychomotor performance: a study of variously active older adult men     

Christensen CL  Payne VG  Wughalter EH  Yan JH  Henehan M  Jones R 《Research quarterly for exercise and sport》2003,74(2):136-142

This research examined varying levels of physical activity and psychomotor and physiological function in variously active older men. Very active moderately active, and low active participants were tested on simple (SRT) and choice reaction time (CRT), coincidence-anticipation timing (CAT), and VO2max. No significant differences for age or height were found, although percentage of fat, and weight were statistically different. Active groups were leaner and lighter. VO2max was significantly different between groups, as physically active groups yielded geater values. SRT and CAT also yielded significantly different results with more active participants showing better performance. No between-groups significant differences resulted for CRT. Generally, increased levels of physical activity were related to superior physiological outcomes and improved psychomotor peformance.  相似文献   

What makes a cMOOC community endure? Multiple participant perspectives from diverse cMOOCs     

Maha Bali  Maureen Crawford  Rhonda Jessen  Paul Signorelli  Mia Zamora 《Educational Media International》2015,52(2):100-115

Imagine the challenge of being immersed in a dynamic learning network where you play brinkmanship with being overwhelmed by a plethora of information, comments, and conversations on a topic of intense interest to you. Through adept facilitation, the comments and encouragement of fellow participants, and your own perseverance, you develop a network of personal connections which serve as metaphorical flying buttresses creating enough stability that you are able to learn in a new, yet profoundly meaningful way – the connectivist massive open online course (cMOOC) way. Through the lens of autoethnography, five seasoned educators collaboratively reflect on their motivation for participating in their initial cMOOC. They analyze their lived experience, what they found most engaging, and most importantly, they grapple with why cMOOC communities often endure past official end-dates. This article attempts to provide insight into the thrill and depth of learning and connection possible through participation in cMOOCs.  相似文献   

Boarding schools: A longitudinal examination of Australian Indigenous and non-Indigenous boarders’ and non-boarders’ wellbeing     

Anthony Dillon  Rhonda G. Craven  Jiesi Guo  Alexander S. Yeung  Janet Mooney  Alicia Franklin  Rob Brockman 《British Educational Research Journal》2022,48(4):751-770

Improving educational outcomes for Indigenous Australian students is a key strategy to helping Indigenous people reach their full potential. This has resulted in well-intentioned efforts by Australian educators and governments to ensure Indigenous children have positive school experiences. However, Indigenous students still lag behind their non-Indigenous counterparts in educational outcomes. This is particularly so for Indigenous students living in rural and remote parts of Australia where educational opportunities are limited, especially in high school. One solution to this problem has been to enrol these students in boarding schools in urban and metropolitan centres. While research on the success of boarding schools for Indigenous students is scarce, what little that does exist is not encouraging. The focus of this research was to examine the effects of boarding for Indigenous (n = 11) and non-Indigenous students’ (n = 158) wellbeing (N = 1423) in two large private boys’ schools. Participating students aged 12–18 years old completed a survey measuring wellbeing constructs on two occasions, 12 months apart. Non-Indigenous boys were generally higher in wellbeing compared with Indigenous boys. There was also evidence of improved social wellbeing beyond that of non-Indigenous boarders over time. Overall, while evidence of merit was weak, boarding schools may benefit their Indigenous students’ development in social wellbeing.  相似文献

The Influence of Criminal Justice Major on Punitive Attitudes     

Tara O’Connor Shelley  Courtney A. Waid  Rhonda R. Dobbs 《Journal of Criminal Justice Education》2013,24(4):526-545

Students majoring in criminology and criminal justice are assumed to have more detailed and accurate knowledge about crime, criminal justice, and punishment practices than peers majoring in other disciplines. The purpose of this study was to examine if criminology/criminal justice majors were more or less punitive than students pursuing other majors at three universities using standard predictors of punitiveness that have not been consistently examined in previous research. The results indicate that criminology and criminal justice students are more punitive in the combined three‐campus sample and in two of the three‐campus samples considered separately.  相似文献   

A conjoint experiment of how design features affect evaluations of participatory platforms     

Henrik Serup Christensen 《Government Information Quarterly》2021,38(1):101538

Online participatory platforms are introduced to boost citizen involvement in political decision-making. However, the design features of these platforms vary considerably, and these are likely to affect how prospective users evaluate the usefulness of these platforms. Previous studies explored how prevalent different design features are and how they affect the success of platforms in terms of impact, but the attitudes of prospective users remain unclear. Since these evaluations affect the prospects for launching successful participatory platforms, it is imperative to assess what citizens want from such digital possibilities for participation. This study uses a conjoint experiment (n = 1048) conducted in Finland that explore the impact of seven design features: Discussion possibilities; Interaction with politicians and experts; Information availability, Aim of participation; Identity verification; Anonymous participation and Accessibility. Furthermore, it is examined whether the effects differ across use of ICTs measured by generation, time online and prior use of participatory platforms. The results suggest that most design features have clear effects on evaluations, and that deliberative features have the strongest effects. Furthermore, the effects are relatively stable across prior use although the less experienced put a stronger emphasis on verification.  相似文献
