We are encouraged by Cobb's (2022) description of changes to the Morpholex profiling tool (https://www.lextutor.ca/cgi-bin/morpho/lex/) resulting in more accurate word classifications. This addresses one point in our recent commentary on Morpholex and on Laufer and Cobb's (2020) study using Morpholex (McLean & Stoeckel, 2021). However, Cobb…

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…

This paper contributes to a research program within extensive reading (ER) and "Reading in a Foreign Language" using corpora to simulate ER input to develop vocabulary through incidental learning to 9,000 words. This helps researchers/teachers evaluate ER. If corpora indicate no 'pathway' from smaller to larger vocabulary sizes through…

Some words in English are derived words, i.e., words with an affix that changes their part of speech, like know "(v)" [right arrow] "knowable (adj)," or meaning, like "pleasant (adj)" [right arrow] "unpleasant (adj)." As a reading teacher, Tom Cobb had always believed that derived words were not particularly…

Graded readers are a great asset to learners acquiring the vocabulary of another language. Homonyms, on the other hand, are a recognized source of trouble for students with that same goal. Publishers of graded readers control the presentation of old and new words, but does this control extend to homonyms? Are only the word forms controlled for--in…

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.…
