“…Teachers’ use of sites such as Twitter and Facebook has been heavily researched (Carpenter & Krutka, 2014, 2015; Cinkara & Arslan, 2017; Davis, 2015; Greenhalgh & Koehler, 2017; Manca & Ranieri, 2016; Rehm & Notten, 2016), both in the United States and internationally. Of emerging interest to educational researchers is how preservice and inservice teachers use sites such as Pinterest, TpT, YouTube, and Instagram to support professional learning and classroom curriculum design (Carpenter et al, 2018; Gallagher et al, 2019; Pittard, 2017; Polikoff & Dean, 2019; Sawyer et al, 2020; Sawyer & Myers, 2018; Schroeder et al, 2019). To differentiate these sites from the more generalized language of “online resources,” Shelton et al (2020) have termed these sites (including Twitter, Facebook, Pinterest, Instagram, TpT, YouTube, Patreon, Amazon Ignite, and teacher blogs) the TOMI , as teachers use them to share curricular materials sometimes at a cost, sometimes for free, in online spaces.…”
