“…Diverse techniques have already been developed and used to study those different cognitive skills involved when solving problems where processing digital information is crucial. For instance, logging protocols recording the actions made on the computer screen (e.g., Van Deursen, Görzig, Van Delzen, Perik, and Stegeman, 2014), eye-tracking measuring the flow of visual attention (e.g., Mason, Pluchino, and Ariasi, 2014;Jarodzka, Janssen, Kirschner, and Erkens, 2015), and verbal protocols expressing cognitive activities (e.g., Brand-Gruwel et al, 2009;Gerjets, Kammerer, and Werner, 2011). However, each technique provides a partial caption of the cognitive skills involved in IPS; consequently, this shows an incomplete understanding of the entire IPS process.…”
