This study explored the lexical coverage of corpus-based vocabulary lists (general, academic, and content-specific) across several million tokens gathered from digital science resources (DSR) for middle school (6-8 grade) students in the United States. The goal was to estimate the extent to which a combination of well-known word lists, mostly…

Research on the relationship between vocabulary knowledge and reading has largely focused on literal comprehension of informational texts. The present study, however, investigates the vocabulary-reading relationship by specifically examining critical reading skills in an argumentative text.76 EFL university students majoring in Education and…

While research demonstrates the importance of vocabulary knowledge for reading comprehension (Anderson & Freebody, 1981; Guo, Roehrig, & Williams, 2011), many studies suggest wide reading exposure for vocabulary acquisition (Nagy, Herman, & Anderson, 1985; Stahl & Nagy, 2006). However, there is compelling evidence for the benefits…

Age of acquisition (AoA) is a measure of word complexity which refers to the age at which a word is typically learned. AoA measures have shown strong correlations with reading comprehension, lexical decision times, and writing quality. AoA scores based on both adult and child data have limitations that allow for error in measurement, and increase…

The American Education Research Association (AERA) is one of the largest education conferences in the world. Using the AERA Open Access Repository, we created a 5,000,000 word corpus of over 18,000 abstracts. We explored the coverages of the New General Service List (NGSL), the New Academic Word List (NAWL), and the Social Science Word List…

Studies of lexical coverage are valuable because they reveal the importance of vocabulary knowledge to comprehension. Lexical profiling research is also extremely useful because it indicates the vocabulary knowledge necessary to understand different text types such as novels, newspapers, academic lectures, television programs, and movies.…

Knowledge of morphemes, the smallest meaningful units within words, contributes to word reading skills, vocabulary, and text comprehension. However, selecting which morphemes to teach can present a challenge for teachers. To date, researchers have not systematically analyzed morphemes in English words to determine which ones are most useful for…

Vocabulary's relationship to reading proficiency is frequently cited as a justification for the assessment of L2 written receptive vocabulary knowledge. However, to date, there has been relatively little research regarding which modalities of vocabulary knowledge have the strongest correlations to reading proficiency, and observed differences have…

This study examined how well second language (L2) recall and recognition vocabulary tests correlated with a reading test, how well each vocabulary test discriminated between reading proficiency levels, and how accurate each test was in predicting reading proficiency when compared with corpus studies. A total of 116 college-level learners of…

The present study aims to investigate the effects of gloss use, L2-gloss frequency and learner proficiency on incidental L2 lexical acquisition. A total of 163 university students in China were assigned to one of the three reading conditions: no gloss (NG), higher frequency L2 gloss (HFLG) and lower frequency L2 gloss (LFLG). The participants read…

This study investigates a novel approach to automatically assessing essay quality that combines natural language processing approaches that assess text features with approaches that assess individual differences in writers such as demographic information, standardized test scores, and survey results. The results demonstrate that combining text…

This study used a randomized pretest-posttest control group design to examine the effect of the integration of corpora in general English courses on the students' vocabulary development. To enhance the learners' lexical repertoire and thereby improve their reading comprehension, an online corpus-based approach was integrated into 42 hours of…

Acknowledging the important role of reading in the university curriculum, and the important role that vocabulary plays in successful reading comprehension, researchers have directed a great deal of effort toward identifying ways that teachers and learners of English for Academic Purposes (EAP) can maximize vocabulary development efforts. Due to…

The aim of this study was to find ways to improve online reading and vocabulary learning. Various new types of online reading comprehension and vocabulary development programs and tests were compared in this study to consider how useful they may be for guiding individual or classroom L2 vocabulary instruction. It explored how these programs seek…
