“…In practice, this can result in educators departing from CI's core principles, such as in making decisions via intuition over evidence, not assessing the effectiveness of chosen interventions, or acting and identifying solutions before understanding the problem (Allen & Calhoun, 1998;Copland, 2003;Detert et al, 2000;Hubers et al, 2017;Mintrop & Zumpe, 2019;Nelson, 2009). Efforts to use improvement science to support the scaling up of reforms have similarly been constrained in practice by political fragmentation (Hannan et al, 2015;Russell et al, 2019;Tichnor-Wagner et al, 2017). For example, Redding and Viano (2018), studying a networked partnership, found that in the hopes of garnering staff buy-in and addressing the prior histories of reform efforts, teacher leaders developed less disruptive changes that were also less likely to substantially improve teaching.…”
