YesNoテストのデータは日本の大学生99名を対象に収集された。彼らの一般的な英語熟達度はCommon European Framework of Reference for LanguagesでA2レベルであった。
The AWL-based Yes/No test utilized in this study was specifically designed for a conceptual replication of Hashimoto and Egbert (2019) investigating the effect of a set of empirically determined lexical sophistication variables on academic word knowledge (Vitta et al., under review). In total, the instrument comprised 108 randomly selected words from sublists 5 through 10 of the AWL, with 16 words from each of sublists 5 through 9, and 18 words from set 10. Words with more than one word class, for example, panel (v) and panel (n), were excluded from the selection process. In addition, 72 pseudowords from Hashimoto and Egbert (2019) were incorporated into the instrument to assess evidence of guessing. Hashimoto’s pseudowords were derived from the 2000 to 4000 frequency bands according to the Corpus of Contemporary American English (COCA; Davies, 2008). All 180 words, plus eight practice items, were administered to the participants in a randomized order through a Google Form, which included a consent form and instructions written in Japanese or Arabic depending on the test site location. Each word constituted an item, and participants were instructed to click a radio button representing yes or no depending on whether or not they “knew” the word. All responses were automatically saved to a spreadsheet for analysis.
