Is There a Future for Journalism?     

Guy Berger 《Journalism Practice》2018,12(8):939-953

A functionalist perspective on the future of journalism would posit that because human society needs journalism, we will find ways to support this communications practice. Yet such a perspective, however consoling, assumes a teleology that is far from guaranteed. What will happen is far from easy to predict; nevertheless, this paper pinpoints several key issues that impact on the future of journalism. It also advances some general propositions and a broad periodisation around UNESCO’s historical role in relation to these issues. The analysis gives particular attention to political and economic matters, the safety of journalists and internet governance. Each of these dimensions entails existential threats to journalism, but some opportunities are also noted. Four paradoxes are also identified, with tensions that may lead to change in one direction or another.  相似文献

Reciprocal Versus Nonreciprocal Assessment of Knee Flexors and Extensors in Concentric Actions Using the CON-TREX Multijoint Isokinetic Dynamometer: A Reliability Study     

Alex Bliss  Jeanne Dekerle 《Measurement in physical education and exercise science》2019,23(2):118-123

Knee flexor and extensor muscular assessment via isokinetic dynamometry is common practice and established in the research literature. However, reporting assessment methodology regarding reciprocal and nonreciprocal movements is often vague or absent. Such methodological issues are crucial for accurate assessments. Therefore, knee extensor and flexor peak moment using either reciprocal movement or nonreciprocal modalities was assessed. Fifteen participants performed three blocks of five concentric muscle actions at three angular velocities [1: nonreciprocal (maximal active flexion followed by passive extension); B2: reciprocal (maximal active extension followed by maximal active flexion); B3 nonreciprocal (maximal active extension followed by passive flexion)]. ANOVA revealed statistically significant within-subject modality effects for peak knee extensor moment and flexor velocity and modality differences (p < .05). Reciprocal and nonreciprocal assessments give significantly different results, with nonreciprocal giving higher peak moments. Reporting which modality is used is crucial to allow for greater clarity for the reader and practitioner.  相似文献   

European standards for quality assurance and institutional practices of student assessment in the UK,the Netherlands and the Czech Republic     

Jan Kohoutek 《Assessment & Evaluation in Higher Education》2014,39(3):310-325

This article analyses the student assessment procedures of 12 universities in the UK, the Netherlands and the Czech Republic with respect to their alignment with the European standards and guidelines on the quality of assessing higher education students (European Standards and Guidelines for Quality Assurance [ESG] 1.3). Based on qualitative methodology combining document review with semi-structured interviews, the analysis has yielded three major results. First, the assessment procedures of the UK universities studied indicate the highest alignment with the ESG 1.3 when compared to the Czech institutions, with the Dutch universities occupying the middle ground. Second, a preference for summative assessment to account for pressures of massification can be observed at institutions in all three countries. Third, it is argued that contrary to some (ministerial) expectations, the influence of the ESG on institutions seems to be insignificant, due to unawareness of the ESG 1.3 at all of the UK and Dutch universities analysed and only moderate knowledge of ESG 1.3 in the Czech case. For this reason, there seems to be a need for communicating the ESG to higher education institutions rather than revising the scope of the ESG as envisaged in the 2012 Bologna policy document (Bucharest Communiqué).  相似文献

Formative Assessment: A Meta‐Analysis and a Call for Research     

Neal Kingston  Brooke Nash 《Educational Measurement》2011,30(4):28-37

An effect size of about .70 (or .40–.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K‐12 were reviewed. Many of the studies had severely flawed research designs yielding uninterpretable results. Only 13 of the studies provided sufficient information to calculate relevant effect sizes. A total of 42 independent effect sizes were available. The median observed effect size was .25. Using a random effects model, a weighted mean effect size of .20 was calculated. Moderator analyses suggested that formative assessment might be more effective in English language arts (ELA) than in mathematics or science, with estimated effect sizes of .32, .17, and .09, respectively. Two types of implementation of formative assessment, one based on professional development and the other on the use of computer‐based formative systems, appeared to be more effective than other approaches, yielding mean effect size of .30 and .28, respectively. Given the wide use and potential efficacy of good formative assessment practices, the paucity of the current research base is problematic. A call for more high‐quality studies is issued.  相似文献   

Evidence for data missing at random in youth physical activity monitoring research     

P. F. Saint-Maurice  Y. Kim  G. J. Welk 《Journal of sports sciences》2017,35(5):484-490

This study examined whether or not activity monitor data collected as part of a typical 7-day physical activity (PA) measurement protocol can be expected to be missing at random. A total of 315 participants (9–18 years) each wore a SenseWear Armband monitor for 7 consecutive days. Participants were classified as “compliant” (86 boys and 124 girls) if they had recorded accelerometer data during 70% or more of the predefined awake time (7 AM–10 PM) on four different days; and “non-compliant” (44 boys and 51 girls) when not meeting these criteria. Linear mixed models were used to examine differences in energy expenditure (EE) levels by compliance across 10 different time periods. The results indicated that non-compliant girls were older (13.4 ± 2.9 vs. 12.2 ± 2.5) and taller (156.8 ± 10.3 vs. 152.8 ± 11.3) than their same gender compliant peers (P < .05). Comparisons of EE rates at segmented portions of the day revealed no differences between compliant and non-compliant groups (P ≥ .05). Differences in EE ranged from ?0.32 kcal · kg^?1 · h^?1 (before school time) to 0.62 kcal · kg^?1 · h^?1 (physical education class) in boys and ?0.39 kcal · kg^?1 · h^?1 (transportation from school) to 0.37 kcal · kg^?1 · hour^?1 (recess) in girls. The results showed that compliant and non-compliant individuals differed in a few demographic characteristics but exhibited similar activity patterns. This suggests that data were considered to be missing at random, but additional work is needed to confirm this observation in a representative sample of children using other types of activity monitors and protocols.  相似文献

Aiming for autonomy: formative peer assessment in a final-year undergraduate course     

Brent Carnell 《Assessment & Evaluation in Higher Education》2016,41(8):1269-1283

This article takes a dual focus on the theme of student formative peer assessment. On the one hand it offers a thorough literature review in this field, while on the other it unpacks a case study of curriculum design where peer assessment has been adopted. The practical example draws on recent changes made to a third- and final-year undergraduate research dissertation course in a UK architectural school. Although peer assessment worked quite well in this small setting, similar findings might be uncovered when scaled up to larger cohorts, as well as other disciplines and year groups. The research findings are certainly relevant for other contexts. Qualitative research from a focus group with six students on the course informs the empirical body of the paper. Through engaging with students’ reflections, as well as the relevant literature, and reflexively looking at the curriculum changes, this paper discusses some of the benefits and drawbacks that can arise from peer assessment in this context. Peer assessment is not without its challenges and hiccups, but, despite these, the benefit to autonomous critical thinking cannot be understated. And arguably peer assessment is especially germane for final-year undergraduates as they embark on employment or more advanced studies.  相似文献
