“…Most widely used instruments are (1) think-aloud protocols, that consists of registering the utterances that the user is verbalising while solving a task (Ericsson and Simon, 1993), (2) retrospective reporting, in which participants report the thoughts while they are working on a task immediately after task performance (Van Gog, Paas, Van Merriënboer, and Witte, 2005), and (3) cued-retrospective reporting, in which participants are prompted with recordings of their task performance including recordings of their actions and eye movements (Hansen, 1991), and therefore the task performance is not influenced by the fact of verbalising their thoughts at the same time (Schmeck, Opfermann, Van Gog, Paas,and Leutner, 2015;Schwonke, Berthold and Renkl, 2009). Concerning product assessment, the task performance can be analysed through: (1) answer forms, that are the answers given by the users while solving the task, which are collected or registered in order to apply a qualitative or quantitative analysis (e.g., Pifarré and Argelagós, 2020;Somerville et al, 2008;Walhout, Oomen, Jarodzka and Brand-Gruwel, 2017). And (2) portfolios, that are able to collect, store, and create working products in different formats as a result of the learning process of acquiring Figure 1.…”
