Earlier studies have estimated the percentage of vocabulary necessary for second language learners to understand written texts as being between 95% (\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"#b23\">Laufer, 1989<\/jats:ext-link>\n                    ) and 98% (\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"#b15\">Hu &amp; Nation, 2000<\/jats:ext-link>\n                    ). In this study, 661 participants from 8 countries completed a vocabulary measure based on words drawn from 2 texts, read the texts, and then completed a reading comprehension test for each text. The results revealed a relatively linear relationship between the percentage of vocabulary known and the degree of reading comprehension. There was no indication of a vocabulary \u201cthreshold,\u201d where comprehension increased dramatically at a particular percentage of vocabulary knowledge. Results suggest that the 98% estimate is a more reasonable coverage target for readers of academic texts.\n                  <\/jats:p>","DOI":"10.1111\/j.1540-4781.2011.01146.x","type":"journal-article","created":{"date-parts":[[2011,2,26]],"date-time":"2011-02-26T10:21:35Z","timestamp":1298715695000},"page":"26-43","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":390,"title":["The Percentage of Words Known in a Text and Reading Comprehension"],"prefix":"10.1111","volume":"95","author":[{"given":"NORBERT","family":"SCHMITT","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XIANGYING","family":"JIANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"WILLIAM","family":"GRABE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,2,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511732935"},{"key":"e_1_2_7_3_1","first-page":"231","volume-title":"Advances in reading\/language research","author":"Anderson R.
