In this article we present a new method for estimating children's total vocabulary size based on a language corpus in German. We drew a virtual sample of different lexicon sizes from a corpus and let the virtual sample "take" a vocabulary test by comparing whether the items were included in the virtual lexicons or not. This enabled us to…

Word Generation (WG) is a research-based vocabulary program for middle school students designed to teach words through language arts, math, science, and social studies classes. The program consists of weekly units that introduce 5 high-utility target words through brief passages designed to spark active examination and discussion of contemporary…

The starting age of foreign language learning has been a controversial issue since the second half of the 20th century. Despite this long time, definite answers have not been found regarding the different aspects of the age issue, i.e., its influence on rate, route and ultimate attainment. Many researchers have explored the influence of age on the…

Two ways of measuring change are presented and compared: A conventional "change score", defined as the difference between scores before and after an interim period, and a process-oriented approach focusing on detailed analysis of conceptually defined response patterns. The validity of the two approaches was investigated. Vocabulary…

"Time to Act," a 2009 report of the Carnegie Corporation's Council on Advancing Adolescent Literacy, concludes that U.S. students are ill-prepared for the literacy challenges of 21st century higher education, employment, and citizenship. Word Generation (WG) is a research-based vocabulary program for middle school students designed to…

The associations between vocabulary growth and reading development were examined longitudinally for a representative sample of Dutch children throughout the elementary school period. Data on basic and advanced vocabulary, word decoding, and reading comprehension were collected across the different grades. The results showed significant progress on…

Eighty-one Korean children were tested once a year across Grades 4, 5, and 6 on Korean phonological and morphological awareness, speeded-naming, Hangul word recognition, Hangul spelling, and English word reading. With age, gender, and Korean vocabulary knowledge statistically controlled, both phonological awareness and speeded-naming were uniquely…

In two experiments we examined how children's nonword pronunciations are influenced by learning words. In Experiment 1, children pronounced nonwords before and after learning words sharing orthographic rimes with the nonwords. These rimes varied in spelling-to-sound consistency and regularity. Children's nonword pronunciations were more sensitive…

The present study examined whether specific item characteristics, such as mode of acquisition (MoA) of word meanings, make reading comprehension tests particularly difficult for deaf children. Reading comprehension data on nearly 13,000 hearing 7-to-12-year-olds and 253 deaf 7-to-20-year-olds were analyzed, divided across test levels from second…
