Predicting Web 2.0 use among US teens—Expanding the power of the skill,will and tool model     

David G. Grant 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(6):3405-3419

There is a need to understand antecedents to US teens’ use of information and communication technology (ICT). Research on the “digital divide” for access to ICT reports conflicting findings based on gender and demographic factors of parent income and education. This study expanded the “tool-will-skill” framework to examine how demographic factors, access to ICT tools, teen will factors and social networking skill explain variation in Internet use among US teens. The study analyzed national data from Pew Research Center’s survey of 1,060 US teens. Principal component analysis (PCA) identified six latent variables for teen will. A pre-diagram depicts a conceptual framework and causal assumption of relationships between demographic factors, tool factors (ie, Internet access, smartphone access and tablet access), will factors (from PCA) and skill factors (Facebook, Instagram, Snapchat and Twitter). Multiple linear path analysis was conducted, and results reported. Recommendations are suggested for instructional practice, educational policy and future research.  相似文献   

Neurological models of cognitive processing     

W. Grant Willis 《Learning and individual differences》1989,1(4)

A framework is proposed from which to evaluate contemporary neurological models of cognitive processing. Selected models are classified as unidimensional, bidimensional, or tridimensional according to the neuraxes that they address. The empirical research that supports each model is considered in terms of anatomical, physiological, and behavioral levels of analysis. Applied implications of the models for learning and individual differences are identified as they relate to psychoeducational assessment and intervention. Finally, differences and similarities among the selected models are synthesized.  相似文献   

Disseminate your findings     

Grant MJ 《Health information and libraries journal》2012,29(1):1-2

While research training often takes place during every day practice, for the majority of library and information professionals, essential training will have been received as part of the dissertation element of their degree. However, there is a danger that important dissertation study findings are not disseminated if, for example, the student has moved onto a new job. The Health Information and Libraries Journal seek to address this research/practice gap with the introduction of a new feature 'Dissertations into Practice' specifically tasked with providing a safe and structured environment for students to disseminate their dissertation project findings.  相似文献   

Informing UK Information Management pedagogic practice: The nature of contemporary higher education culture     

Kevin Grant  Ray Hackney  David Edgar 《International Journal of Information Management》2010

This paper explores the nature of Information Management (IM) pedagogic practice within UK higher education (HE), by exploring the history of IM and teasing out what this may mean for its teaching. Empirical evidence is considered from both qualitative and quantitative data analysis perspectives through the application of Grounded theory.  相似文献   

The Management of Quality Assurance: A Review of International Practice   总被引：2，自引：0，他引：2  

Grant Harman 《Higher Education Quarterly》1998,52(4):345-364

Current and recent international practice in the management of quality assurance for higher education systems and institutions is reviewed. Particular attention is given to administrative agencies or units with responsibility for the management of quality assurance at both national and institutional levels; whether participation in reviews and other activities is optional or compulsory; the main methodologies employed; the focus of quality assurance activities; the purposes of such activities; and reporting and/or follow-up activities.  相似文献

Factors influencing physiological responses to small-sided soccer games   总被引：3，自引：2，他引：1  

Rampinini E  Impellizzeri FM  Castagna C  Abt G  Chamari K  Sassi A  Marcora SM 《Journal of sports sciences》2007,25(6):659-666

The aim of this study was to examine the effects of exercise type, field dimensions, and coach encouragement on the intensity and reproducibility of small-sided games. Data were collected on 20 amateur soccer players (body mass 73.1 +/- 8.6 kg, stature 1.79 +/- 0.05 m, age 24.5 +/- 4.1 years, VO(2max) 56.3 +/- 4.8 ml x kg(-1) x min(-1)). Aerobic interval training was performed during three-, four-, five- and six-a-side games on three differently sized pitches, with and without coach encouragement. Heart rate, rating of perceived exertion (RPE) on the CR10-scale, and blood lactate concentration were measured. Main effects were found for exercise type, field dimensions, and coach encouragement (P < 0.05), but there were no interactions between any of the variables (P > 0.15). During a six-a-side game on a small pitch without coach encouragement, exercise intensity was 84 +/- 5% of maximal heart rate, blood lactate concentration was 3.4 +/- 1.0 mmol x l(-1), and the RPE was 4.8. During a three-a-side game on a larger pitch with coach encouragement, exercise intensity was 91 +/- 2% of maximal heart rate, blood lactate concentration was 6.5 +/- 1.5 mmol x l(-1), and the RPE was 7.2. Typical error expressed as a coefficient of variation ranged from 2.0 to 5.4% for percent maximal heart rate, from 10.4 to 43.7% for blood lactate concentration, and from 5.5 to 31.9% for RPE. The results demonstrate that exercise intensity during small-sided soccer games can be manipulated by varying the exercise type, the field dimensions, and whether there is any coach encouragement. By using different combinations of these factors, coaches can modulate exercise intensity within the high-intensity zone and control the aerobic training stimulus.  相似文献   

The association of objectively determined physical activity behavior among adolescent female friends     

Schofield L  Mummery WK  Schofield G  Hopkins W 《Research quarterly for exercise and sport》2007,78(2):9-15

The purpose of this study was to examine the extent to which physical activity among adolescent female friends is interdependent. The participants were 318 adolescent girls with a mean age of 16.0 years (range: 15-18 years). Pedometry was used to assess physical activity over 4 days. The relationship between an individual girl and her first-nominated reciprocal friend's physical activity level was moderate (r = 0.45, 90% confidence interval = 0.31, 0.56), when the friendship was nonreciprocal it was trivial (r = -.06, 90% confidence interval = -.36 .25). Friends'physical activity levels explained between 27% and 32% of an individual's pedometer-determined physical activity level. Reciprocity of friendship is an important variable to consider when understanding the relationship between adolescent female friends' physical activity. When friendships are reciprocal, there is a stronger relationship between friends' physical activity.  相似文献

Utility of international normative 20 m shuttle run values for identifying youth at increased cardiometabolic risk     

Duncan S. Buchan  Gareth Knox  Anwen M Jones  Grant R Tomkinson  Julien S. Baker 《Journal of sports sciences》2019,37(5):507-514

The purpose of this study was to examine the ability of international normative centiles for the 20 m shuttle run test (20mSRT) to identify youth at increased cardiometabolic risk. This was a cross-sectional study involving 961 children aged 10–17 years (53% girls) from the United Kingdom. Receiver operating characteristic (ROC) curves determined the discriminatory ability of cardiorespiratory fitness percentiles for predicting increased cardiometabolic risk. ROC analysis demonstrated a significant but poor discriminatory accuracy of cardiorespiratory fitness in identifying low/high cardiometabolic risk in girls (AUC = 0.58, 95% CI: 0.54–0.63; p = 0.04), and in boys (AUC = 0.59, 95% CI: 0.54–0.63; p = 0.03). The cardiorespiratory fitness cut-off associated with high cardiometabolic risk was the 55^th percentile (sensitivity = 33.3%; specificity = 84.5%) in girls and the 60^th percentile (sensitivity = 42.9%; specificity = 73.6%) in boys. These 20mSRT percentile thresholds can be used to identify children and adolescents who may benefit from lifestyle intervention. Nonetheless, further work involving different populations and cardiometabolic risk scores comprising of different variables are needed to confirm our initial findings.  相似文献
