“…A large body of empirical research illustrates the beneficial role of explanation in learning (e.g., Coleman, Brown, & Rivkin, 1997;Legare, 2014;Legare & Lombrozo, 2014;Lombrozo, 2006;Rittle-Johnson, Saylor, & Swygert, 2007), especially within the domain of biological knowledge (e.g., Au et al, 2008;Keil, Levin, Richman, & Gutheil, 1999;Wellman, Hickling, & Schult, 1997). In particular, parent explanations during informal science activities may help children practice formal scientific thinking, develop deeper and more coherent scientific theories, and acquire scientific problem solving skills (Crowley, 2000;Fender & Crowley, 2007).…”
