Therefore, the present study confirms the findings of numerous previous studies that also conclude there are no significant differences in student performance with regard to the scheduling configuration used at the school (Bateson, 1990;Cobb, Abate, & Baker, 1999;Duel, 1999;Lare, Jablonski, & Salvaterra, 2002;Lockwood, 1995;Snyder, 1997;Veal & Schreiber, 1999;Wild, 1998) and refutes findings of previous studies that either conclude block-scheduled students perform better on standardized tests than traditionally scheduled students (Evans, Tokarczyk, Rice, & McCray, 2002;Hess, Wronkovich, & Robinson, 1999;Mattox, Hancock, & Queen, 2005, Payne & Jordan, 1996Queen, Algozzine, & Eaddy, 1996) or traditionally scheduled students outperform block-scheduled students (Arnold, 2002;Gruber & Onwuegbuzie, 2001;Knight, DeLeon, & Smith, 1999;Lawrence & McPherson, 2000;Pisapia & Westfall, 1997). ...
