“…The goal of SETs is to determine the teachers’ teaching effectiveness (Marsh, 2007). Such instruments have been used throughout academia for a long time, but their validity, reliability, and usefulness are still being challenged (Aleamoni, 1974, 1999; Aleamoni and Hexner, 1980; Arreola, 2007; Costin et al , 1971; Feldman, 1978, 1984; Marsh, 1984, 2007; Marsh and Roche, 1997; Rodin and Rodin, 1972; Wright et al , 1984). This makes sense since teaching is a complex activity (Shulman, 1987), so the factors used to measure a teacher’s effectiveness are multidimensional (Marsh, 1991, 2007; Marsh and Bailey, 1993) and difficult to comprehend.…”
