“…Numerous studies focused on the best ways to memorize a word's spelling (e.g., Bosman, van Hell, & Verhoeven, 2006;Hilte & Reitsma, 2006;Hubbert, Weber, & McLaughlin, 2000); ways to learn a spelling rule (e.g., Darch, Eaves, Crowe, Simmons, & Conniff, 2006;Hilte & Reitsma, 2011;Kemper, Verhoeven, & Bosman, 2012); and how to encourage students to apply spelling rules in a structured way (e.g., Butyniec-Thomas & Woloshyn, 1997;Paffen & Bosman, 2005). 1 An important insight is that spelling regularities have to be made explicit, spelling rules need to be explained, and the application of spelling rules has to be practiced until mastery (Berninger et al, 1998;Henry, 1989).…”
