“…Traditionally and still too frequently preservice teachers are “placed” for their clinical experiences with veteran practitioners through what is sometimes pejoratively referred to as the “cannon method”: they are “launched” into classrooms to observe haphazardly-identified mentor teachers whose sole qualification is that they volunteer to serve in such a role (Guha, Hyler, & Darling-Hammond, 2017; Parker, Groth, & Byers, 2019). In contrast, Hannah and 11 of her English, math, science and social studies preservice teacher peers had the opportunity to work in a “critical, project-based” (CPB) clinical structure (Dutro, Cartun, Melnychenko, Haberl, & Pacheco Williams, 2018; Pytash & Zenkov, 2018, Pytash & Zenkov, 2018). This clinical experience involved an intentionally selected mentor (the seventh author, Kitchen), a boundary-spanning university-based teacher educator (the first author, Zenkov), four teacher education doctoral students from our local university (the second, third, fourth and sixth authors—Taousakis, Goransson, Staudt and Stephens), an independent researcher (the fifth author, Ewaida) and two other veteran teachers from the school (the eighth and ninth authors, Hostutler and Castorena).…”
