“…Results of intervention studies in vocabulary development with older students with reading difficulties yield positive outcomes using a variety of approaches, including mnemonics, cognitive strategy instruction, direct instruction, activity-based methods, and computer-assisted instruction (Jitendra, Edwards, Sacks, & Jacobson, 2004). Approaches that use explicit instruction combined with activities that engage students in manipulating words and word meanings (e.g., mnemonics, word associations) appear to be the most effective for increasing vocabulary and maintaining the use of the newly learned words (Mastropieri, Scruggs, & Graetz, 2003;Bryant, Goodwin, Bryant, & Higgins, 2003).Because understanding the words that are read and being able to find the meaning of unknown words is an integral part of reading comprehension, most successful approaches for reading comprehension combine vocabulary and comprehension techniques (Bauman, Edwards, Boland, Olejnik, & Kame'enui, 2003;Beck, McKeown, & Kucan, 2002). Although approaches to teaching reading comprehension can be quite varied, three features are common to most successful interventions for older students in this area.…”
