“…Therefore, many researchers (Ramey & Ramey, 2006;Raspa, McWilliam, & Ridley, 2001;Ridley, McWilliam, & Oates, 2000) have used measures of child engagement within childcare settings to assess the quality with which early childhood programs are serving children with special needs, while others have directly examined the efficacy of early intervention programs by measuring children's engagement (e.g., McWilliam, Trivette, & Dunst, 1985). Moreover, to promote engagement skills, researchers have developed interventions (e.g., Miller, Strain, Boyd, Jarzynka, & McFetridge, 1993;Reinhartsen, Garfinkle, & Wolery, 2002;VanDerHeyden, Snyder, Smith, Sevin, & Longwell, 2005) as well as examined teacher or curriculum variables that might influence the quality of engagement (e.g., McWilliam, Scarborough, & Kim, 2003) in various contexts.…”
