Examining teacher effectiveness through value-added scores and observed teaching practices
Value-added assessment is designed to measure teacher contributions to student achievement in order to promote effective teaching (Battelle for Kids, 2011b; Darling-Hammond et al., 2012; Lee, 2011). When value-added assessment is used, research indicates that in some cases effective teaching is promoted, but in other cases it is not (Amrein-Beardsley & Collins, 2012; Darling-Hammond et al., 2012; Betebenner et al., 2012; McCaffrey & Hamilton, 2007; Quattrochi & Chapman, 2010). One reason that effective teaching may not be promoted is value-added models are not specifically designed to be diagnostic tools of effective teaching (Betebenner et al., 2012; Darling-Hammond, et al., 2012; Goe, 2008; RAND Corporation, 2004). Empirical evidence about which specific teaching practices improve student learning is lacking and additional research is needed (Goe, 2008; RAND Corporation, 2004; Stronge, Ward, & Grant, 2011).
