“…The studies used both qualitative and quantitative methods to analyze the opinions of the students about the quality of teaching and learning in higher education (Cohen et al, 2007;Johnson & Christensen, 2014;Miller et al, 2004;Silverman, 2010;Creswell, 2012). For qualitative research in education, some techniques have been so common such as structured observation (Cohen et al, 2007;Tafahomi, 2021b), photography (Hemyari et al, 2013;Tafahomi, 2021e;Alerby, 2000), interviews and questionnaires (Ez zy, 2002;Johnson & Christensen, 2014). In addition, the quantitative method was used widely for research through questionnaires and surveys (Frankfort-Nachmias et al, 2014;Creswell & Creswell, 2018) in different styles to discover the opinions of the students about different educational parameters (Lee, 2005;Xi et al, 2017;Yang et al, 2013;Tafahomi, 2021a).…”
