Measurement of vocabulary knowledge: Problems and solutions

Abstract

It has been widely acknowledged that vocabulary plays a significant role in second language acquisition. To a large degree, learners’ improvement in L2 acquisition depends on their progress in acquiring individual words and word parts (Barcroft, 2004). Meara and Fitzpatrick (2000) claimed that communicative effectiveness can be achieved more successfully by learners with a larger vocabulary pool than by those with a more detailed command of a smaller one.
