A longitudinal,quantitative study of student attitudes towards audio feedback for assessment     

Mitchell Parkes  Peter Fletcher 《Assessment & Evaluation in Higher Education》2017,42(7):1046-1053

This paper reports on the findings of a three-year longitudinal study investigating the experiences of postgraduate level students who were provided with audio feedback for their assessment. Results indicated that students positively received audio feedback. Overall, students indicated a preference for audio feedback over written feedback. No statistically significant differences were found between male and female students’ attitudes, suggesting that both sexes held similar attitudes towards audio feedback. Students also indicated a preference for audio feedback that was recorded simply and returned promptly over delayed, more sophisticatedly recorded and edited feedback.  相似文献

概率密度函数法研究重构吸引子的结构     

陆宏伟  陈亚珠  卫青 《上海大学学报(英文版)》2004,8(1)

Probability density function (PDF) method is proposed for analysing the structure of the reconstructed attractor in computing the correlation dimensions of RR intervals of ten normal old men.PDF contains important information about the spatial distribution of the phase points in the reconstructed attractor.To the best of our knowledge, it is the first time that the PDF method is put forward for the analysis of the reconstructed attractor structure.Numerical simulations demonstrate that the cardiac systems of healthy old men are about 6-6.5 dimensional complex dynamical systems.It is found that PDF is not symmetrically distributed when time delay is small, while PDF satisfies Gaussian distribution when time delay is big enough.A cluster effect mechanism is presented to explain this phenomenon.By studying the shape of PDFs, that the roles played by time delay are more important than embedding dimension in the reconstruction is clearly indicated.Results have demonstrated that the PDF method represents a promising numerical approach for the observation of the reconstructed attractor structure and may provide more information and new diagnostic potential of the analyzed cardiac system.  相似文献

Exploring online students’ self-regulated learning with self-reported surveys and log files: a data mining approach     

Moon-Heum Cho  Jin Soung Yoo 《Interactive Learning Environments》2017,25(8):970-982

Many researchers who are interested in studying students’ online self-regulated learning (SRL) have heavily relied on self-reported surveys. Data mining is an alternative technique that can be used to discover students’ SRL patterns from large data logs saved on a course management system. The purpose of this study was to identify students’ online SRL patterns with the use of data mining techniques. We examined both self-reported self-regulation surveys and log files to predict online students’ achievements and found using log files was more powerful in predicting students’ achievements in an online course than self-reported survey data. Discussions to enhance teaching and learning practices with the use of data mining are provided.  相似文献
