Description: | Co-Principal Investigator(s): Beck, Isabel; McKeown, Margaret Purpose: In this project, the researchers explored how vocabulary-related instruction in schools might reduce the differences in reading achievement between students who enter school with large vocabularies and those who enter school with substantially smaller vocabularies. Project Activities: The research team completed a series of laboratory experiments with college students relying on measures of brain wave activity (ERP) and eye-tracking technology in order to provide fine-grain temporally sensitive measures of word processing and comprehension. One area of particular interest was to determine if being familiar with a word (as a result of instruction) leads to the construction of a similar mental representation as knowing a word (prior to instruction). The researchers hypothesized that some types of vocabulary instruction may facilitate familiarity with spelling and pronunciation of new words, whereas others may facilitate knowledge of both form and meaning. In addition to these experimental studies, a classroom study was conducted to determine the effects of increased direct instruction on word learning outcomes for kindergarten and first grade students (see Beck & McKeown, 2007).
