“…Among included studies with learning achievement in focus, only 5% involved qualitative data-collection techniques. A number of authors recommend exploring the topic via a mixed-method approach (Alt & Raichel, 2020;Segura-Robles et al, 2020;Aşıksoy, 2018;Hew et al, 2016;Huang et al, 2019b;Ortiz-Rojas, Chiluiza & Valcke, 2019;Torres-Toukoumidis et al, 2021;Wichadee & Pattanapichet, 2018). Specifically, involving more interview data in addition to the data collected via quantitative means (Aşıksoy, 2018;Hew et al, 2016;Huang et al, 2019;Ortiz-Rojas, Chiluiza, & Valcke, 2019;Wichadee & Pattanapichet, 2018) and triangulating the data collected via self-report questionnaires or qualitative techniques with the observational data would be a good idea (Segura-Robles et al, 2020;Alt & Raichel, 2020).…”
