‘I like the sound of that’ – an evaluation of providing audio feedback via the virtual learning environment for summative assessment     

Clare Carruthers  Brenda McCarron  Peter Bolan  Adrian Devine  Una McMahon-Beattie  Amy Burns 《Assessment & Evaluation in Higher Education》2015,40(3):352-370

This study aims to ascertain student and staff attitudes to and perceptions of audio feedback made available via the virtual learning environment (VLE) for summative assessment. Consistent with action research and reflective practice, this study identifies best practice, highlighting issues in relation to implementation with the intention of redesigning activities in the light of the findings. It utilises four case studies where audio feedback was provided to students using the Wimba voice authoring tool within Blackboard Learn+ for various types of summative assessment. The intention was to identify how and in what context audio feedback via the VLE is effective and why. The research was undertaken via a combination of techniques, including a student survey and staff reflective logs. The findings indicate that students liked the convenience, effectiveness, flexibility and personalised nature of this feedback, but raised concerns with some aspects of the technology. This paper also makes practical recommendations for the use of the feedback mechanism, focusing on the most effective use of the digital medium, and highlights directions for future research.  相似文献   

Ranking Romanian academic departments in three fields of study using the g-index     

Adrian Miroiu  Mihai Păunescu 《Quality in Higher Education》2015,21(2):189-212

The scientific performance of 64 political science, sociology and marketing departments in Romania is investigated with the aid of the g-index. The assessment of departments based on the g-index shows, within each of the three types of departments that make up the population of the study, a strong polarisation between top performers (very few) and weak performers (much more numerous). This alternative assessment is also found to be largely consistent with an official ranking of departments carried out in 2011 by the Ministry of Education. To conduct the evaluation of departments the individual scientific output of 1385 staff members working in the fields of political science, sociology and marketing is first determined with the aid of the ‘Publish or Perish’ software based on the Google Scholar database. Distinct department rankings are then created within each field using a successive (second-order) g-index.  相似文献   

Intelligent analysis of the quality of education through teaching practices on virtual campuses     

Alvarez-Blanco  Lucia  Castro-Lopez  Adrian  Cervero  Antonio 《European Journal of Psychology of Education - EJPE》2023,38(3):1111-1128

ICTs have been increasingly involved in teaching–learning processes due to the potential offered by the tools as well as to the set of demands derived from the political and health situations of the social environment. In this sense, the introduction of virtual campuses as complex systems that centralize the entire technological component that complements traditional teaching processes has meant a change of paradigm with repercussions at the teaching and pedagogical level. In this context, the purpose of this study aims to analyze students’ perception of the use of virtual campus and how to enhance the quality of the educational process using intelligent systems. For this purpose, 318 students that use virtual campus have been surveyed. The results show that there are three variables that predominantly influence the quality of teaching–learning processes using virtual campuses: frequent contact with teachers through the platform, the digital competence of the student, and the adaptation of training content to the students’ prior knowledge. This information can be useful, as it allows them to establish guidelines to guide the practices of their teaching teams in technological environments, guaranteeing the suitability of the teaching–learning process and improving the evaluation processes and the assessment of their own educational work.

Exploring athletic identity in elite-level English youth football: a cross-sectional approach     

Tom O. Mitchell  Mark Nesti  David Richardson  Adrian W. Midgley  Martin Eubank 《Journal of sports sciences》2014,32(13):1294-1299

Abstract

This study is the first empirical investigation that has explored levels of athletic identity in elite-level English professional football. The importance of understanding athletes’ psychological well-being within professional sport has been well documented. This is especially important within the professional football industry, given the high attrition rate (Anderson, G., & Miller, R. M. (2011). The academy system in English professional football: Business value or following the herd? University of Liverpool, Management School Research Paper Series. Retrieved from http://www.liv.ac.uk/managementschool/research/working%20papers/wp201143.pdf) and distinct occupational practices (Roderick, M. (2006). The work of professional football. A labour of love? London: Routledge). A total of 168 elite youth footballers from the English professional football leagues completed the Athletic Identity Measurement Scale (AIMS). Multilevel modelling was used to examine the effect of playing level, living arrangements and year of apprentice on the total AIMS score and its subscales (i.e., social identity, exclusivity and negative affectivity). Football club explained 30% of the variance in exclusivity among players (P = .022). Mean social identity was significantly higher for those players in the first year of their apprenticeship compared to the second year (P = .025). All other effects were not statistically significant (P > .05). The novel and unique findings have practical implications in the design and implementation of career support strategies with respect to social identity. This may facilitate the maintenance of motivation over a 2-year apprenticeship and positively impact on performance levels within the professional football environment.  相似文献

Single maximal versus combination punch kinematics     

Piorkowski BA  Lees A  Barton GJ 《Sports biomechanics / International Society of Biomechanics in Sports》2011,10(1):1-11

The aim of this study was to determine the influence of punch type (Jab, Cross, Lead Hook and Reverse Hook) and punch modality (Single maximal, 'In-synch' and 'Out of synch' combination) on punch speed and delivery time. Ten competition-standard volunteers performed punches with markers placed on their anatomical landmarks for 3D motion capture with an eight-camera optoelectronic system. Speed and duration between key moments were computed. There were significant differences in contact speed between punch types (F(2,18,84.87) = 105.76, p = 0.001) with Lead and Reverse Hooks developing greater speed than Jab and Cross. There were significant differences in contact speed between punch modalities (F(2,64,102.87) = 23.52, p = 0.001) with the Single maximal (M+/- SD: 9.26 +/- 2.09 m/s) higher than 'Out of synch' (7.49 +/- 2.32 m/s), 'In-synch' left (8.01 +/- 2.35 m/s) or right lead (7.97 +/- 2.53 m/s). Delivery times were significantly lower for Jab and Cross than Hook. Times were significantly lower 'In-synch' than a Single maximal or 'Out of synch' combination mode. It is concluded that a defender may have more evasion-time than previously reported. This research could be of use to performers and coaches when considering training preparations.  相似文献   

The effect of a supported exercise programme in patients with newly diagnosed Type 2 diabetes: a pilot study     

Backx K  McCann A  Wasley D  Dunseath G  Luzio S  Owens D 《Journal of sports sciences》2011,29(6):579-586

The aim of this study was to examine the effectiveness of either a standard care programme (n = 9) or a 12-week supported exercise programme (n = 10) on glycaemic control, β-cell responsiveness, insulin resistance, and lipid profiles in newly diagnosed Type 2 diabetes patients. The standard care programme consisted of advice to exercise at moderate to high intensity for 30 min five times a week; the supported exercise programme consisted of three 60-min supported plus two unsupported exercise sessions per week. Between-group analyses demonstrated a difference for changes in low-density lipoprotein cholesterol only (standard care programme 0.01 mmol · L(-1), supported exercise programme -0.6 mmol · L(-1); P = 0.04). Following the standard care programme, within-group analyses demonstrated a significant reduction in waist circumference, whereas following the supported exercise programme there were reductions in glycosylated haemoglobin (6.4 vs. 6.0%; P = 0.007), waist circumference (101.4 vs. 97.2 cm; P = 0.021), body mass (91.7 vs. 87.9 kg; P = 0.007), body mass index (30.0 vs. 28.7 kg · m(-2); P = 0.006), total cholesterol (5.3 vs. 4.6 mmol · L(-1); P = 0.046), low-density lipoprotein cholesterol (3.2 vs. 2.6 mmol · L(-1); P = 0.028), fasting β-cell responsiveness (11.5 × 10(-9) vs. 7.0 × 10(-9) pmol · kg(-1) · min(-1); P = 0.009), and insulin resistance (3.0 vs. 2.1; P = 0.049). The supported exercise programme improved glycaemic control through enhanced β-cell function associated with decreased insulin resistance and improved lipid profile. This research highlights the need for research into unsupported and supported exercise programmes to establish more comprehensive lifestyle advice for Type 2 diabetes patients.  相似文献   

Public libraries as reserves of cultural and digital capital: Addressing inequality through digitalization     

Adrian Leguina  Sabina Mihelj  John Downey 《Library & information science research》2021,43(3):101103

Public libraries are among key sites for the acquisition of cultural capital, and possibly one of the most potent means through which the state can address inequality. While digitalization of public libraries already attracted significant scholarly attention, the evidence of its contribution to the acquisition of cultural skills and knowledge and social mobility remains limited, as does the conceptual understanding of links between digitalization, cultural capital, and social stratification. This article draws on two disconnected bodies of research, the sociological analysis of cultural capital and stratification and research on digital divides. To bridge these two bodies of research, the interplay of cultural and digital capital in public libraries was investigated. The extensive dataset from the UK Taking Part Survey (2016–17) was analyzed using two-step cluster analysis and multinomial regression models to explore the contrasting profiles of contemporary library users. Results identify four distinct user groups: Traditional, Active, Family, and Tech Access, which possess different degrees of cultural and digital capital, have different demographic profiles, and benefit from digitalized libraries in different ways. If libraries are to fulfil their role in reducing social inequalities, it is important that they tailor their digital services to the specific characteristics of each user group. This approach also provides a useful template for exploring the interplay of digitalization and (in)equality in other cultural institutions.  相似文献
