臺灣的越南語教材常用詞檢視之研究：以詞頻為基礎

A Word-Frequency-Based Study on Frequent Words of Vietnamese Textbooks in Taiwan

本研究檢視兩本初級越南語教材之詞彙量及其出現頻率，以現有越南語料庫之詞頻資訊為參照，來探討教材編著者所選擇的詞彙之特徵，並檢視不同教材是否提供學習者相同的基本詞彙，再探討詞頻異同點的具體表現，以供越南語教師在教學應用的參考，以及初級越南語教材詞彙編輯的初步規範參考。研究方法採內容分析法。經研究發現，這兩本教材的詞彙量適宜，與過去關於外語教材的詞彙量之研究結果一致。在詞頻方面，兩本教材的高頻詞以關係動詞là（是）與人稱代詞為主；低頻詞雖然只能覆蓋詞彙總出現次數的小部分，卻約佔總詞彙量的一半；詞頻表現與現有語料庫之詞頻資訊較不一致。根據上述結果，本研究提出相關具體建議。

This research investigated the word frequency and the vocabulary size of two elementary Vietnamese textbooks. Based on the word frequency information of the contemporary Vietnamese corpora, the present research aimed to explore the characteristics of the vocabulary that the authors selected, and to examine whether different textbooks provide the same basic vocabulary for learners, and then to explore the similarities and differences of the word frequency of these two Vietnamese textbooks. The results of this study hopefully can be used for reference for Vietnamese language teachers in teaching, as well as preliminary reference for vocabulary editing standards of elementary Vietnamese textbooks. This research applied the content analysis method. This study found that, the vocabulary of these two textbooks was appropriate, consistent with the results of previous researches on the vocabulary size of foreign language textbooks. In terms of word frequency, the high-frequency words of the two textbooks mainly contained be verb“là”and personal pronouns. Although the low-frequency words can only cover a small part of the total number of words, they occupied about half of the total vocabulary. The word frequency results are inconsistent with the word frequency information of the existing Vietnamese corpora. Based on the above results, this study proposed some specific suggestions.
