Vocabulary development is vital for those using English as an additional language. Sheila Hopkins considers how teachers can identify key vocabulary during lesson planning and outlines strategies for teaching these key words to EAL learners

“The limits of my language are the limits of my mind. All I know is what I have words for.”
Ludwig Wittgenstein

As proficiency in English is “central to understanding achievement” (Strand & Hessel, 2018), vocabulary development becomes a good candidate on which to focus instruction.

When we think of it, language pervades everything we do in education; making vocabulary development a critical component of learning for all pupils, but especially for those using English as an additional language (EAL).

Indeed, learners using EAL look to us for the informed lexical guidance that will allow them to comprehend lesson content, pass exams and make meaningful contributions to all aspects of school life; both social and academic. As such, educators across subject areas, phases and stages cannot afford to leave vocabulary instruction to chance.

In research commissioned by The Bell Foundation, Murphy (2015) found that interventions for learners using EAL aimed at explicitly teaching academic and/or general vocabulary were particularly successful in terms of pupils’ learning of the target vocabulary or in terms of wider literacy-based measures.

One of the most consistent findings in reading research is the extent to which a learner’s vocabulary knowledge directly supports reading comprehension (Graves, 2006), as approximately 95 to 98 per cent of the vocabulary in a text needs to be understood to be able to derive a general meaning of the text (Schmitt, Jiang & Grabe, 2011).

Since vocabulary is implicated in all aspects of learning, teachers must have viable principles and processes for identifying and teaching vocabulary effectively. Attempting to address every single word or phrase that we anticipate is unknown is time-consuming and unrealistic. Indeed, without a clear sense of how to analyse an oral or written text for high-impact vocabulary, a teacher can squander valuable time on words or phrases that have little bearing on a learner’s grasp of key ideas and details.

In this way, the hardest part of vocabulary instruction is not learning the process for teaching a new word or phrase, it is learning how to analyse the lesson in terms of the language it requires and pull out the vocabulary that needs to be taught.

This article first suggests criteria that teachers can use to identify key vocabulary in lesson planning and then provides some strategies for teaching new vocabulary to learners using EAL.


To assist teachers in selecting key vocabulary, scholars have proposed various criteria for analysing the lexical demands of a lesson. Beck, McKeown and Kucan (2002) have provided a widely used classification scheme for organising vocabulary into tiers:

  • Tier I is comprised of everyday vocabulary. For example: Friend, important and answer.
  • Tier II is more advanced academic vocabulary with wide applicability across subject areas. For example: Cause and effect, summarise, therefore.
  • Tier III vocabulary are topic-specific terms used within a particular subject area. For example: Photosynthesis and onomatopoeia.

Curriculum materials can provide a fairly reliable list of Tier III terms tied to and contextualised within subject areas, while often neglecting to mention Tier II terms that learners will encounter across the disciplines.

For example, in a history chapter addressing the Second World War, vocabulary such as “blitzkrieg”, “U-boat” and “Munich Agreement” will predictably be highlighted. However, vocabulary necessary for pupils to understand and discuss the cause/effect relationships of the historical period will not be clarified (i.e. “impact”, “subsequent”, “consequences”).

Moreover, we cannot assume that learners using EAL, particularly those at the early stages of English language development, are proficient in everyday vocabulary associated with Tier I.

Being able to classify vocabulary into tiers does not necessarily help us to pare down vocabulary for instructional purposes when it comes to pupils using EAL. For this, teachers might benefit from a set of practical guidelines that can support them in making informed decisions about which vocabulary will receive attention. Feldman and Kinsella (2008) offer guidelines for prioritising vocabulary in lesson planning:

  • Choose three to four vocabulary items that are important for understanding and discussing the key ideas and details within a unit (i.e. “water cycle”, “condensation”, “evaporation”, “precipitation”).
  • Choose three to four high-utility vocabulary that are useful for learners to engage in literate discourse about the unit and across subject areas (i.e., “water constantly changes”; “changes from liquid to vapour”; “changes from vapour back to liquid”).

Another way to refer to this is to think of topic-related vocabulary as “words or phrases to know” and high-utility vocabulary as “words to go” (Feldman & Kinsella, 2008). We need to balance topic-related terms with high-utility terms that learners will need to use as they apply the topic to speaking and writing tasks.

A reliable source of high-impact vocabulary can come from the list of guiding questions or writing prompts at the end of a reading. Another productive source can be the text summary or a model answer.

A final approach to planning for vocabulary is to teach lexical terms from the perspective of language functions. Here, the language demands are identified by specific academic tasks learners are to accomplish (describing, sequencing, comparing). For example, vocabulary used to compare might include: “One similarity/difference between X and Y is…” And vocabulary used to persuade might include: “In my opinion…”.

The benefit of learning vocabulary used to perform language functions is that it extends beyond a given task. Once a learner knows words and phrases used to compare, they can apply this to a range of contexts across all subject areas.


The question of whether vocabulary is best acquired indirectly via broad reading and social interaction or directly via explicit teaching is a false dichotomy. In reality, learners need a comprehensive approach to vocabulary development that incorporates both direct and indirect approaches to lexical development.

One approach to academic vocabulary instruction is to provide learners with opportunities to develop new concepts using language they already know (either in English or in their home languages) and then attach new vocabulary to those concepts. This differs from pre-teaching a list of key terms.

For example, ask learners to look at a visual diagram of the water cycle and explain what is happening in everyday language, (i.e. “water goes up”), before introducing the new term, “evaporation”. In this way, a learner’s prior knowledge acts as a bridge to learning new vocabulary.

Another approach is to establish a consistent, school-wide, instructional process for directly teaching vocabulary. Feldman and Kinsella (2008), provide an instructional routine that includes the following adaptable steps:

  • Pronounce: At times, pupils may need guidance in how to correctly pronounce new terms.
  • Explain: Understanding new terms requires a clear explanation of the meaning using language that is already present in the learner’s lexicon.
  • Provide examples: Pupils often need at least two or three examples of new vocabulary in use and in different contexts to firmly grasp the meaning.
  • Elaborate: Learners’ understanding of new vocabulary will be strengthened if they are given opportunities to generate their own additional examples and visual representations.

In either approach, you will want to include lots of visual support and hands-on representation to make vocabulary comprehensible. In addition, learners will need multiple encounters with a new word or phrase before they fully acquire the vocabulary. Therefore, teachers need to provide opportunities for learners to retrieve and interact with new vocabulary in a variety of ways over an extended period of time.


Teach words in context: Pupils benefit from noticing a word’s context through the company that words keep. For example: “read volume two”, “turn down the volume”, “measure the volume of water”. In this regard, it is better to teach vocabulary in phrases rather than single words.

Advanced organisers: To actually “own” a word means to know a great deal about it. To support in-depth word knowledge use organisers that go beyond simple word definition.

Sentence frames: Sentence frames can effectively demonstrate vocabulary usage in different contexts. Take, for example, the word “factor”:

  • One major ___ that can contribute to a low mark on a test is ___.
  • One of the most important ___ when I purchase a gift is ___.

Learners can rate their knowledge of vocabulary before and after a unit of study.

Translanguaging: A child’s home language(s) is one of the most valuable resources available for learning an additional language. Ask learners to use and create bilingual dictionaries and glossaries. These can be shared with other learners and saved for next year’s class. Multilingual learners can also create “personal dictionaries” in notebooks or mobile devices for words of personal significance. There are plenty of online multilingual resources to use for pre-teaching concepts and vocabulary, (try, for example, the bilingual search engine 2Lingual).

Vocabulary study: Involve pupils in a variety of activities to help process and embed vocabulary. These should be short and lively. Consider group activities that use word associations, such as:

  • Think of vocabulary associated with democracy.
  • Give an example and a non-example of democracy.
  • Role-play what democracy looks like.
  • See who can use the word democracy most during the week.

Or ask learners to create games using a learning tool – such as those available free via Quizlet. The overall goal is to promote joy in building vocabulary.
