Textbooks play an essential role in foreign language programs; however, it is unclear if their contents match the most salient linguistic forms championed by usage-based approaches to second language acquisition (SLA). Through the lens of a corpus-based approach via lexical frequency, this study evaluates five of the most popular Arabic textbooks. Vocabulary was vowelled and lemmatized using the MADAMIRA morphological analyzer and compared to the first 3,000 most frequent words from A frequency dictionary of Arabic using AntWordProfiler. Results show a relatively low number of items at each frequency band, and subsequent recommendations are made for filling lexical gaps in Arabic and L2 textbooks.

评估阿拉伯语教科书：基于语料库的词汇频率研究

教科书在外语课程中起着至关重要的作用；然而，尚不清楚它们的内容是否与基于使用的第二语言习得 (SLA) 方法所倡导的最显着的语言形式相匹配。通过词汇频率的基于语料库的方法，本研究评估了五本最受欢迎的阿拉伯语教科书。使用 MADAMIRA 形态分析器对词汇进行元音和词形还原，并使用 AntWordProfiler与阿拉伯语频率词典中的前 3,000 个最常用词进行比较。结果显示每个频段的项目数量相对较少，随后提出了填补阿拉伯语和 L2 教科书词汇空白的建议。
