Measuring Second Language Vocabulary
Acquisition
SECOND LANGUAGE ACQUISITION
Series Editor: Professor David Singleton,Trinity College, Dublin, Ireland
This series brings together titles dealing with a variety of aspects of language
acquisition and processing in situations where a language or languages other than
the native language is involved. Second language is thus interpreted in its broadest
possible sense. The volumes included in the series all offer in their different ways, on
the one hand, exposition and discussion of empirical fi ndings and, on the other, some
degree of theoretical refl ection. In this latter connection, no particular theoretical
stance is privileged in the series; nor is any relevant perspective – sociolinguistic,
psycholinguistic, neurolinguistic, etc. – deemed out of place. The intended readership
of the series includes fi nal-year undergraduates working on second language
acquisition projects, postgraduate students involved in second language acquisition
research, and researchers and teachers in general whose interests include a second
language acquisition component.

Introduction
Much of the literature on second language acquisition as a general
process (e.g. Mitchell & Myles, 2004; Lightbown & Spada, 1999) pays
little attention to vocabulary learning. This is not just a recent
phenomenon. O’Dell (1997: 258) comments that vocabulary and lexis
are absent from major books on the syllabus and theory of language
teachingthroughoutthe1970sand1980s.Itsomissionmayhaveaneven
longerhistory. Wilkins (1972: 109),writing at the beginningof the 1970s,
suggests it dates from the development of structural linguistics. For
much of the last half century or so, therefore, the consideration of
vocabulary in the process of language learning, testing and teaching
appearsto have been sidelined and, as Meara (1980) describes it, turned
into a Cinderella subject.
I think there are three reasons for this. One is a product of the
structural and other approaches to language teaching that have become
highly pervasive in language teaching. Outside the arena of specialist
vocabularystudiesthereseemstobealong-standingideathatwordsare
just words, and that learning words is unsystematic. Vocabulary is
unchallenging as a pedagogical or an academic issue, as a consequence.
Instructuralapproachestolearning,thepartoflanguagelearningwhich
is really important is how languagerules and systems areacquired, and
with this approach we need not be too concerned about the words to
which these rules and systems apply. It is assumed that these rules
would develop regardless of which words, or how many words, were
being used to form them. Commonly, a structural linguistic approach to
teaching deliberately reduces the volume of vocabulary input at the
earliest stages of learning to only what is necessary for the presentation
of language structures, or what is essential to motivate learners. So
powerful has this approach been, that it has pervaded later approaches

vocabulary learning sidelined.
The second reason is the persistent belief among teachers, learners
and educational administrators, that it is possible to become highly
proficient in a foreign language, and even a sophisticated user, with
only very limited vocabulary resources. I am constantly surprised,
for example, by the number of teachers who quote Ogden’s (1930)
Simple English at me, apparently in all seriousness, and are under the
