“…In their seminal study on the self-explanation effect, Chi, Bassok, Lewis, Reimann, & Glaser (1989) found that, when studying example exercises in a physics text, the best learners spontaneously explained the material to themselves, providing justifications for each action in a solution sequence. Subsequent studies have shown that prompting for such self-explanations can lead to improved learning outcomes in numerous domains including arithmetic (Calin-Jageman & Ratner, 2005;Rittle-Johnson, 2006;Siegler, 2002), geometry (Aleven & Koedinger, 2002;Wong, Lawson & Keeves, 2003), interest calculations (Renkl, Stark, Gruber & Mandel, 1998), LISP programming (Bielaczyc, Pirolli, & Brown, 1995), argumentation (Schworm & Renkl, 2007), Piagetian number conservation (Siegler, 1995), probability calculation (Große & Renkl, 2003), biology text comprehension (Chi, DeLeeuw, Chiu, & LaVancher, 1994), and balancing beam problems (Pine & Messer, 2000).…”
