Research vocabulary size • Question: how large should a receptive vocabulary be? • Approach 1: to calculate all words in English • 114,000 word families (Goulden, Nation, & Reed, 1990) • 85,500 (Nagy & Anderson, 1984) • Approach 2: to see what the NS know • A well-educated NS: 20,000 word families • Approach 3: to find out how much is needed for typical language use • Around 5,000 (Hirsh & Nation, 1992)
Research cognitive studies • How is L2 word represented in learner’s mind? • How is the meaning accessed? • Directly in L2? • Through learner’s L1? • How are the words from the same word family stored in our mental lexicon? • Individually? • In groups? • How are the words retrieved? • As holistic units? • Get assembled in the process?
General recommendations (P. Nation) • Teaching a word: a small amount of information at a time • Spend more time on high-frequency words, words that fill a language need (technical words) • The learning burden of a word: • Meaning (meaning/ referents/ associations) • Form (spoken/ written/ word parts) • Use (grammatical functions/ collocation/ constraints on use)
A good vocabulary exercise should be … • focusing on useful words (high frequency) • emphasizing the useful aspects of learning burden • setting useful learning conditions • involving learners in active work with a word • avoiding interference

Potential research topics • Preparing high- and low-frequency word lists for your academic discipline • Comparing learners’ use of a specific word (a word combination) to that in a corpus of specialized authentic texts (e.g., research articles, book chapters, etc. published in your discipline) • Analyzing learners’ typical mistakes in vocabulary use (e.g., form/meaning/context) • Exploring contextual/ meaning differences of special vocabulary compared to their general meaning/use
