The Development of Passive and Active Vocabulary in a Second Language: Same or Different?

LAUFER, B.·1998·Applied Linguistics

Abstract

The study investigates the gains in three types of English as a Foreign Language vocabulary knowledge, passive, ‘controlled active’ and free active, in one year of school instruction. It also examines how these aspects of lexical knowledge are related to one another, and what changes occur in these relationships after one year Gains in vocabulary were measured by comparing two groups of learners with six and seven years of instruction Relationships among the three areas of knowledge were investigated by comparing them within the same individuals The results show that passive vocabulary size (as measured by Vocabulary Levels Test) progressed very well, controlled active vocabulary (as measured by the productive version of the Levels Test) progressed too but less than the passive Free active vocabulary (as measured by Lexical Frequency Profile) did not progress at all Passive vocabulary size was larger than controlled active in both groups of subjects, but the gap between the two types of knowledge increased in the more advanced group. Passive and controlled active size scores correlated with each other well Free active vocabulary, on the other hand, did not correlate with the other two types. The results raise several questions about the nature of vocabulary knowledge and the effect of instruction on vocabulary growth

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
