Below is a short video which briefly demonstrates how to insert standard deviation (SD) error bars into a column chart using Microsoft (MS) Excel (2010 version). This is something that many of my undergraduate students have asked me to show them over the past week (as their dissertations are due in next week!) and so… Continue Reading »
Asynchronous e-learning has formed a major part of my Technology Enhanced Learning (TEL) project so far, through the combined use of video technology and a text-based discussion forum. During my TEL project presentation, however, I talked about utilising synchronous e-learning as part of my TEL project too. Therefore, I set out to gather some published… Continue Reading »
For traditional (i.e. face-to-face) module delivery, there is general agreement among higher education researchers that attendance and achievement are positively correlated, especially for lecture-based modules (Johnes, 1990; Smith and Naylor, 2001; Newman-Ford et al., 2008; Clark et al., 2011). For online module delivery (particularly when delivered asynchronously), however, students are not required to “attend” per… Continue Reading »
Simply stated, stiffness describes the association between a given force and the subsequent deformation of an object (5, 7). The term stiffness originated in physics and is based upon Hooke’s Law, which is defined as F = kx, where F is the force required to deform an object, k is the proportionality constant and x… Continue Reading »
