“…Most computerbased scaffolding that incorporates fading employs fixed fading, in which scaffolds are removed after a fixed time interval and are thus not completely adapted to student ability. Many intelligent tutoring systems and advanced learning analytics implement performance-adapted fading based on assessment of student performance (Cope & Kalantzis, 2015;VanLehn, 2008;West, 2012), but many scholars criticized the use of fading by computer systems due to inaccurate diagnosis of students' behavior, intention, and learning progress (Jackson, Krajcik, & Soloway, 1998;Jonassen & Reeves, 1996;Madaio, 2015). In the case of fading based on teachers' judgment, teachers need to determine the timing of fading as a result of examining each student's learning process.…”
