Building on Jack Richard's interest in vocabulary, this paper looks at the importance of morphology (how words are formed) in language learning and teaching. It describes why knowledge of morphology is important, and how it affects vocabulary learning. It provides clear guidelines on what word parts to focus on, how much time to spend on word…

Most teachers are concerned about the teaching of vocabulary. However, it is much more effective to focus on the ways in which vocabulary can be learned. This article looks at the jobs of the teacher, which include, in order of importance, (1) designing a balanced course, (2) organizing classroom work and homework, (3) training the learners in how…

Two commonly used test types to assess vocabulary knowledge for the purpose of reading are size and levels tests. This article first reviews several frequently stated purposes of such tests (e.g., materials selection, tracking vocabulary growth) and provides a reasoned argument for the precision needed to serve such purposes. Then three sources of…

This book is written for teachers of young children aged from 5 to 12 years in primary schools who want to support students' English vocabulary. Most of these children will be native speakers of English, although the increasing cultural and linguistic diversity of our communities suggests a significant number will be from homes where other…

In this article Paul Nation responds to Thomas Cobb's "Numbers or Numerology? A Response to Nation (2014) and McQuillan (2016)" (EJ1117024). Nation begins by clarifying his own position on vocabulary learning and goes on to highlight points made in Cobb's article with which he is in agreement, while drawing from his 2014 article,…

This study looks at how much input is needed to gain enough repetition of the 1st 9,000 words of English for learning to occur. It uses corpora of various sizes and composition to see how many tokens of input would be needed to gain at least twelve repetitions and to meet most of the words at eight of the nine 1000 word family levels. Corpus sizes…

Extensive reading is one of a range of activities that can be used in a language learning course. Ideally, the choice of activities to go into a course should be guided by principles which are well supported by research. Similarly, the way each of those activities is used should be guided by well-justified principles. In this article, we look at…

This article describes the development and validation of a Vietnamese bilingual version of the Vocabulary Size Test--a test which measures written receptive vocabulary size. The test can be used to measure the English vocabulary size of Vietnamese learners of English. A learner's total vocabulary size is calculated by multiplying their test result…

Examines effective ways of building vocabulary among learners of English as a Second Language. Discusses using word cards, studying word parts, and using a dictionary and highlights the keyword approach. (Author/VWL)

Examines research on learning related vocabulary, such as lexical sets, a unit of vocabulary or specific items sharing certain formal or semantic features. This research shows that learning related words at the same time makes learning them more difficult and suggests that this difficulty can be avoided if related words are learned separately.…

Offers advice for teaching English-as-a-Second-Language vocabulary in a way that makes a difference for students and boosts their sense of achievement. (Author/VWL)

Examines the potential for vocabulary learning using a corpus of 42 grade readers from one series of graded readers (seven at each of six levels in the series). It was found that in order to have 95% coverage of the running words at a level in the series, it was necessary to already know the vocabulary of the current level in the scheme.…

This study compared four different approaches to identifying technical words in an anatomy text. The first approach used a four step rating scale, and was used as the comparison for evaluating the other three approaches. It had a high degree of reliability. The least successful approach was that using clues provided by the writer such as labels in…

A word frequency study of two graded readers and an unsimplified text indicated that graded readers facilitated better foreign-language reading and vocabulary learning than did unsimplified texts. It was found that students needed to read several same-level texts to master vocabulary, and that vocabulary mastery was not necessary for successful…

Comparison of the effectiveness of two story selection processes for English-as-a-Second-Language learners indicated that selecting "running" stories (a story and its follow-up articles) provided more repetition of low frequency words, better reduced vocabulary load, and provided better conditions for vocabulary acquisition than did selecting…
