Abstract
When does taking time to preview a new word before reading a story improve vocabulary and comprehension more than encountering the word in context? To address this question, the 2001-2002 version of Project LISTEN's Reading Tutor embedded an automated experiment to compare three types of vocabulary preview -- defining the word, giving a synonym, or just asking about the word -- and a control condition. Outcomes included within-story comprehension as measured by performance on multiple-choice cloze questions, and post-story vocabulary as measured by matching words to their definitions. We analyze results based on thousands of randomized trials.
