“…With notable exceptions (e.g., in biology Urban-Lurain et al, 2013;Beggrow et al, 2014;Weston et al, 2015;Vitale et al, 2015Vitale et al, , 2019Zhai et al, 2020), there are fewer examples of digital tools designed to automatically measure practices in complex, less well-defined problem spaces, in large part because of the difficulty in valid automatic scoring (e.g., Beggrow et al, 2014;Ha and Nehm, 2016). Furthermore, few studies compare assessment between pen and paper vs. digital formats, and those have differing conclusions about student performance across the two environments (e.g., Kumar et al, 1994;Aberg-Bengtsson, 2006;Guimaraes et al, 2018;Oqvist and Nouri, 2018). As development of digital assessment tools increases, the field would benefit from more research on how differences in paper versus digital environment interact with the way students demonstrate understanding through performance tasks.…”
