從教科書建置國中學術詞彙表

Compiling a List of Middle School Academic Vocabulary From Textbooks

學術詞彙是學術場域中進行交流的重要工具，是用以解釋專業術語涵義之輔助性詞彙。相同的學術詞彙可能出現在各領域，但出現頻率會因領域而異。本研究使用國民中小學九年一貫課程綱要之國中階段七科（數學、理化、生物、地科、地理、歷史、公民）教科書以編製學術詞彙表。對語料進行斷詞處理、對照華語八千詞表刪除基本詞彙、再以均勻度等相關指標篩選，整理為包含779個詞彙的「國中學術詞彙表」。儘管篩選過程考量跨領域特性，但各學術詞彙出現於數學科的單元比率與其他各科顯著不同，而依據出現單元比率進行集群分析所得五組學術詞彙，除單純反映出現單元比率高、低之組外，亦有歷史公民組、生物地科地理組、自然領域組。最後本文重新論述學術詞彙的特性、提出國內國中學術詞彙表建置程序的反思、對未來的研究與教學實務提出建議，並指出本研究的限制。

Academic vocabulary is a crucial communication tool in academia. Academic vocabularies are supplementary vocabularies used to define technical terms. The same academic vocabulary might appear in various disciplines, but the frequency will vary. This study compiled an academic vocabulary list using textbooks from the Grade 1-9 Curriculum Guidelines for seven disciplines-mathematics, physics/ chemistry, biology, geoscience, geography, history, and civics. After segmenting the corpus, removing the fundamental terms, and filtering by indicators such as dispersions, we compiled a ＂Middle School Academic Vocabulary List＂ with 779 vocabulary words. The proportion of academic vocabulary occurring in each unit of mathematics was significantly different from that of other disciplines, despite considering cross-discipline features. The cluster analysis was derived from the following five categories: historical and citizen, biology and geography, natural science, and two groups reflecting a higher and lower proportion of occurrence units. Finally, the study examined the characteristics of academic vocabulary and reflected the construction procedure for an academic vocabulary list for middle school students. The study also gives suggestions for future research and teaching, as well as possible limits to the research.
