“…A substantial body of evidence confirms the seriousness of this problem. Some teachers are uncomfortable with mainstreamed children, resent their presence, and treat them differently from their peers (Graham, Burdig, Hudson, & Carpenter, 1980;Schmelkin, 1986); some classmates reject mainstreamed children or socially segregate them (Gottlieb, 1975;Gresham, 1986;Willey & McCandless, 1973); Many mainstreamed children, who often have lower self-esteem than their counterparts in special classes, have difficulties (Barger, 1978;Semmel & Semmel, 1979) and only occasionally show evidence of superior achievement in regular classes (Strain & Kerr, 1981, p. 37). Too frequently it appears that mainstreaming practices result in "parallel streams" of education for the handicapped and nonhandicapped children placed in common classroom settings (Gerold & Barners, 1985).…”
