“…Many studies analyzed in these reviews overlapped with those used in the Moore and Readence (1984) meta-analysis. The literature base represented in these four articles includes studies that examined the following: 1. where the GO was used in the instructional sequence (i.e., before passage reading versus after passage reading; Alvermann, Boothby, & Wolfe, 1984;Barron & Stone, 1974;Simmons, Griffin, & Kameenui, 1988); 2. whether the GO was teacher constructed (Alvermann, 1981(Alvermann, , 1982(Alvermann, , 1988Alvermann & Boothby, 1983Barron & Schwartz, 1984) or student constructed (Barron & Stone, 1974;Bean, Singer, Sorter, & Frazee, 1986;Berkowitz, 1986;Horton, Lovitt, & Bergerud, 1990;Weisberg & Balajthy, 1989, 1990; and 3. whether participants had no disabilities (Alvermann, 1988;Bean et al, 1986;Berkowitz, 1986;Griffin, Malone, & Kameenui, 1995;Hawk, 1986;Simmons et al, 1988;Troyer, 1994) or were diagnosed with LD Darch & Eaves, 1986;Griffin, Simmons, & Kameenui, 1991;Horton et al, 1990).…”
