“…Despite the political and practical imperatives, the challenge of undertaking impact evaluations is well acknowledged. Reasons include lack of funding and allocated research time for scholars of teacher education (Cochran-Smith, 2004; Cochran-Smith et al, 2012); heavy teaching loads and mostly part-time or adjunct status of practicing teacher educators (Borko et al, 2007; Nuttall et al, 2006; Zeichner, 2005); historical separation between research and practice among education school faculty (Labaree, 2004); limited doctoral training on evaluative methods given the dominance of interpretive and design-based research over the past few decades (Borko et al, 2007; Grossman, 2008; Wilson, 2006; Zientek et al, 2008); the lack of teacher education research published in top-ranked, peer-reviewed journals (Grossman, 2008; Wilson et al, 2002; Zeichner, 2005); lack of capacity to engage in multisite and/or multidisciplinary partnerships so as to undertake large-scale evaluations (Borko et al, 2007; Del Schalock et al 2006); difficulty in teacher preparation programs accessing and using data about their graduates’ teaching practice and/or the performance of K–12 students (Goldhaber, 2019); lack of consensus on common measures of teacher effectiveness in teacher preparation programs (Goldhaber, 2019; Grossman, 2008); the politicization of teacher education that leads much research and practice to be reactive to political imperatives and the local teaching market (Cochran-Smith & Villegas, 2015; Grossman & McDonald, 2008).…”
