“…Over the past two decades, many ITS have been successfully deployed to enhance teaching and improve students' learning experience in a number of domains and application areas. In particular, ITS have been actively used to teach technical subjects: from helping students acquire knowledge about mathematics (Büdenbender et al, 2002;Dietrich & Buckley, 2008;Goguadze et al, 2005;Hrastinski et al, 2019;Koedinger & Anderson, 1993;Melis & Siekmann, 2004;Passier & Jeuring, 2006;Sommer & Nuckols, 2004), logic (Abel et al, 2001;Andrews et al, 2004;Burstall, 1998;D'Agostino & Endriss, 1998;Hendriks et al, 2010;Scheines & Sieg, 1994;Stamper et al, 2013;Sufrin & Bornat, 1996), and algorithms (Leelawong & Biswas, 2008); to assisting students in knowledge and skill acquisition in natural sciences (Hume et al, 1996;Makatchev et al, 2011;Zhang & VanLehn, 2016;2017); to teaching real-world applications. Apart from providing students with general assistance and feedback on their performance, ITS are able to address individual student characteristics (Graesser et al, 2017) and cognitive processes (Wu & Looi, 2010).…”
