“…To achieve this objective, we performed a systematic mapping of the literature based on the proposed methodology by Petersen, Robert, Shahid and Mattson (2008) and adjusted by García and Ramírez (2019) and García-Holgado, Marcos-Pablos and García-Peñalvo (2020). Many authors have used this methodology (López et al, 2015;Pérez & Vladimirovna, 2017;Van Eck & Waltman 2017;Howard, Wood & Stonebraker, 2018;Aydoğdu, 2020;Whalley & Barbour, 2020) and agree that the following stages must be carried out: 1) definition of the guidance questions, 2) location of scientific production, 3) refinement of identified scientific production, 4) design of the bibliographic database, and 5) analysis of the bibliographic information.…”
