A Reexamination of Semantic Difficulty: Validating the "Living Word Vocabulary."
Smith, Dean R.
Four studies examined the validity of the "Living Word Vocabulary" (LWV), a corpus of approximately 44,000 alphabetized words with multiple meanings tested at different grade levels. Regressions were performed between the grade level p-values (percentages of students responding correctly to a vocabulary test item) reported by LWV and word frequency, grade-level p-values obtained from three nationally standardized tests, logit difficulties obtained from the Peabody Picture Vocabulary Test (PPVT), and observed difficulties obtained from two sets of words. Results indicated that the LWV seemed to be a valid measure of semantic difficulty. A regression analysis between the LWV and the PPVT produced an equation that allows users of the LWV to place all of the word difficulties upon a common scale, thus allowing cross-grade-level comparisons of the same word. This equation now allows those interested in readability access to the huge corpus of data in the LWV. (Contains 10 references and 5 tables of data.) (RS)
