The TOSR requires the individual to visually analyze four photographs representing a single word in a variety of contexts. The individual must integrate several skills, including visual processing, inferential thinking, and deductive reasoning to choose the single word (from a choice of four) which best represents the commonality among the images. The TOSR was developed by two practicing speech-language pathologists with more than 45 years of combined experience, who recognized the need to measure children’s depth of vocabulary knowledge without relying on expressive language skills (e.g., defining or describing words) . The TOSR is the first of its kind to measure deep, nuanced understanding of words without requiring an oral or written response.  \nOver the last 15 years, researchers have shown increasing interest in the topics of vocabulary acquisition and the impact of vocabulary knowledge on other academic skills. Research indicates that owning a broad, deep vocabulary base is essential to school achievement, and that there is a strong positive reciprocal relationship between word knowledge and reading comprehension (Baumann, Kame’enui, & Ash, 2003; National Institute of Child Health and Human Development [NICHD], 2000; RAND Reading Study Group, 2002; Silverman & Hartranft, 2015) . Mastery of complex vocabulary is required for reading comprehension, which in turn increasingly becomes the cornerstone of education as a student advances. Students must deeply and broadly “own” a significant number of vocabulary words, including words that are not commonly spoken. As students progress through school, they more frequently encounter text containing nuanced words such as compliant and prudent, which communicate a host of subtle meanings. These words are difficult to master because dictionary definitions are hard to parse, meaning can change based  \nSection 1: Introduction 7  \non context, and background knowledge is often needed to recognize appropriate use. According to Hu and Nation (2000), students need to understand 98% of words in a given text in order to comprehend the meaning. By the time students reach the 12th grade, they will need to know upward of 50,000 words in order to comprehend required texts across multiple content areas (Proctor, Silverman, Harring, & Montecillo, 2012) .  \nVocabulary storage involves both phonemic (sound patterns) and semantic (meanings) representations of words. The mental lexicon, which provides organized storage of phonemic representations, is distinct from, but connected to, the storage of word meanings (Levelt, Roelofs, & Meyer, 1999) . Vocabulary breadth refers to the number of lexical entries one has, and depth refers to the extent of semantic representations one has for each known word (Levelt et al., 1999) .  \nBoth breadth and depth independently influence different aspects of reading skill. For example, while vocabulary breadth predicts decoding ability, vocabulary depth may be a better predictor of reading comprehension (Ouellete, 2006; Ouellette & Beers, 2010; Walley, Metsala, & Garlock, 2003) . Highlighting the importance of vocabulary knowledge, in 2009 vocabulary assessment was added to the U.S. Department of Education’s National Assessment of Educational Progress (NAEP) . The NAEP recognized the need to measure students’ ability to apply word knowledge to interpret meaning in text passages. Specifically, the NAEP emphasized the importance of assessing vocabulary depth, noting,“Students may be familiar with the word ‘green’when used in the social context of environmentalism; however, they may not have encountered the word to describe someone lacking in experience, as in ‘green recruit’” (U.S. Department of Education, Institute of","cbCaiaZPXiYPtbvT","https://ap.wps.com/l/cbCaiaZPXiYPtbvT","pdf",464683,"English","# Section 1: Introduction\n## Rationale\n## Vocabulary and reading comprehension background\n## Vocabulary breadth and depth\n## Instruction and assessment importance","[{\"question\":\"What does the TOSR measure and for whom is it designed?\",\"answer\":\"The TOSR measures semantic reasoning skills, especially depth of vocabulary knowledge, for children and adolescents aged 7 through 17.\"},{\"question\":\"How does the TOSR work during the assessment?\",\"answer\":\"An individual analyzes four photographs representing a single word in different contexts and chooses the one word (from four options) that best captures the commonality among the images.\"},{\"question\":\"Why is vocabulary depth important for reading comprehension?\",\"answer\":\"Mastery of complex, nuanced vocabulary supports comprehension; research cited in the text links word knowledge to stronger reading comprehension performance and emphasizes assessing depth rather than only familiarity.\"}]","TOSR Manual Intro - Section 1 - Introduction | PDF",1790629376,18]
