“…As an example, a video can be viewed as a class activity (Koc, 2011;Rosaen et al, 2010a) or as a distance-learning activity (Karsenti & Collin, 2011;Krammer et al, 2006), live (Mitchell, Marsh, Hobson, & Sornsen, 2008;Whyte, 2011) or recorded (Kleinknecht & Schneider, 2013;Wang, 2013), as an occasional activity (Calandra et al, 2008;Tripp & Rich, 2012a) or as part of regular activities (Santagata, 2009;, and alone (Star & Stirkland, 2008;van den Berg, 2001) or in a group (Borko et al, 2008;van Es, 2012). Video viewing is also sometimes combined with other technologies such as electronic portfolios (Cooper, 2015;Fadde et al, 2009), online discussions (Koc, Peker, & Osmanoglu, 2009;Llinares & Valls, 2009;Yamamoto & Hicks, 2007), video-conferencing (Dyke, Harding, & Liddon, 2008;Marsh et al, 2009;Wiesemes & Wang, 2010), "multimodal resources": digital pictures and texts (Roche & Gal-Petitfaux, 2015), DVD and CD-ROM (Chan & Harris, 2005;Yung et al, 2007), TV programmes, 5 or web platforms 6 (Aub e, David, Cantin, & Meyer, 2003;Baecher & Kung, 2011;Leblanc & Ria, 2014). However, the number of tools remains limited due to the high time investment required, particularly for organization and management (Krammer et al, 2006), and the high cost (Koc, 2011).…”
