I have always had an interest in and fascination for the power of vocabulary and remember well the excitement I felt as a child when I successfully tried out a ‘new word’. For example, in Junior 4 (now Year 6), I was introduced to the word ‘consequently’ and wove it into my conversation as often as I possibly could. When my sister, later, introduced me to ‘subsequently’, I was quite transported.
The power of a rich vocabulary and its impact on educational attainment is well documented. In her book Proust and the Squid, Dr Maryanne Wolf reflects on the absence of literacy and asserts that: ‘When words are not heard, concepts are not learned.’ The OUP has recently published a language report entitled 'Why Closing the Word Gap Matters' in which the point is highlighted that the size of a child’s vocabulary is the best predictor of success on future tests and children with a poor vocabulary are three times more likely to have mental health issues. The motivation for Robert Macfarlane’s recent, beautiful publication The Lost Words was a reaction to the revised edition of the Oxford Junior Dictionary (2007) which had ‘dropped’ around forty common words related to nature, such as bluebell, heron, bramble, fern, heather… Macfarlane describes his poems as ‘spells’, intended to be spoken aloud to ‘summon lost words back into the mouth and the mind’s eye’. The importance of a wide vocabulary and the best approach to teaching young children seems a relevant, current debate.
Reflecting on the findings of Ofsted’s 15/16 review of the curriculum and assessment in English, HMI Sally Hubbard reported at a NATE conference (Autumn 2017) on the reading curriculum and in particular asserted that the most-able readers in the primary schools visited, lacked understanding of words that linked to ‘knowledge’. She stated that teachers should use their subject expertise to ensure that pupils can cope with vocabulary that is ‘lexically dense’ and ‘content-specific’. She emphasised the importance of vocabulary and ‘knowledge of the world’ and teachers’ appreciation of how language and understanding the world go hand-in-hand. She talked about the demands of the Key Stage 2 Reading SAT and the requirement for children as readers to be able to, amongst other skills, be able to explain the meaning of words in context and explain how meaning is enhanced through choice of words and phrases.
These language demands were viewed further through the focus of the research by Isabel Beck around Three Tier Vocabulary. In summary, Tier 1 words are those common ‘everyday’ words to which children have plenty of exposure and which quickly become a part of their vocabulary. Tier 2 words are not used commonly in conversation, but are more often found in written materials, whether fiction, information or technical texts. They will be used, for instance, by authors to enhance a story, for literary effect (e.g. misfortune; dignified; faltered) or to provide particular detail in an information piece (e.g. relative; vary; accumulate). Tier 2 words are not context specific but highly generalisable – and often express concepts that children are familiar with but in a more sophisticated or nuanced way. Tier 3 words, by contrast, are technical terms specific to content areas (e.g. lava; circumference; aorta). Recognised as new and ‘difficult’ words, they are often defined by the author of a text and sometimes scaffolded as through a glossary. All three tiers are important for comprehension and vocabulary development although Tier 2 and 3 words require more ‘deliberate effort’ than Tier 1.
In considering this model, Hubbard argues that teachers are good at giving attention to ‘Tier 3’ words - will anticipate them in their planning and offer children explicit instruction around them through such strategies as pre-teaching key words; providing a Word Wall; exploring spelling patterns, word families, derivations. What is lacking, however, is attention to Tier 2 words which, being ‘non content specific’, children will encounter in multiple contexts. It is therefore crucial for teachers to engage children in a consideration of words across different contexts. As an example, Beck outlined an occasion where she read nursery children a story in which there featured the word ‘reluctant’: Lisa was reluctant to leave her teddy bear in the laundrette. In exploring this concept, she asked the children to share a time when they had felt reluctant to do something and the children typically replied thus: . I’d be reluctant to leave my teddy at my friend’s house; I’d be reluctant to leave my drums at my step-mum’s… All of the examples offered by the children, related to leaving something behind. Beck modelled further: I’m reluctant to ride a roller-coaster. Some children are reluctant to eat spinach. Could you tell me something you’d be reluctant to do? Much to her delight, one child replied: I’d be reluctant to change a baby’s diaper.
In light of the survey findings shared by Hubbard, I thought it would be interesting to use the lessons I observe as a Link Tutor, as a lens through which to consider the idea of Two Tier vocabulary instruction. The first opportunity was a science lesson with Year 1. The Learning Objective shared with the children was displayed on a whiteboard: I can describe the physical properties of a variety of everyday objects made from different materials. The trainee asked the class what was meant by the word ‘variety’. One child responded by saying it meant ‘lots’ and the trainee agreed and moved on. In reflecting on this interaction with the trainee after the lesson, in light of the Three Tier Vocabulary model, we established that ‘variety’ fitted the classification of a Tier 2 word – i.e. it is not context specific but used in a range of different contexts. The trainee could appreciate that instead of confirming ‘variety’ meant ‘lots’, as though the words were synonymous, there was, in fact, rather more ‘unpacking’ to be done around the definition. Having a number of something (even ‘lots’) is a prerequisite for having variety, but does not in itself mean there is necessarily difference between them. Considering other contexts in which the children might have encountered the word ‘variety’ would have been valuable as well as then making the link between the meaning of the word in the context of the learning objective and the resources on the children’s tables to be investigated in their science activity.
In a different school, I observed a trainee teaching a grammar lesson to Year 5. The objective was To Build Cohesion Within A Paragraph. The trainee began the lesson by asking the class ‘What does ‘cohesion’ mean – talk to your partner.’ After a moment or two, she took an answer from one child who said ‘time connectives and conjunctions’, to which the trainee replied ‘Yes, well done.’ Of course, this isn’t in fact the meaning of the word ‘cohesion’ - the child had quite cannily offered a phrase spotted at the top of the worksheet on his desk which related to the grammatical terms one might deploy to create text cohesion and which was clearly going to be the focus of the next exercise . The trainee did not explore the meaning of the word further – neither in a wider context, nor in a grammatical one. Part way through the lesson, the trainee drew the class together for a mini-plenary during which she asked a particular pupil to read their work aloud and then asked ‘How can you make that sentence cohesive?’ After a pause, the child said ‘I don’t know’. As an observer, I sensed that the difficulty lay in the fact that the child didn’t know what ‘cohesive’ meant and without further comprehension of the term, could not articulate a reply. Reflecting on the lesson afterwards, the trainee agreed that anticipating the need for discussion around the term ‘cohesion’ would have supported the children’s understanding of the task, their engagement with it and the progress made during the lesson. Out of interest, I asked the trainee how she would define the word herself – in what other contexts she might encounter the word - and she gave me a lovely response: I think of the word in the context of RE – in relation to ‘unity’ – and also the idea of cultural cohesion – and I also associate it with ‘glue’ and sticking things together – oh no...is that ‘adhesive’? In terms of exploring nuance and a range of contexts, this trainee was well able to see the wide applicability of the term cohesion and the merit, in future, of better anticipating those words at the planning stage of a lesson.
In conclusion, I have found this focus a very interesting one as there has always been an instance of a Two Tier word occurring early in the lesson (e.g. ‘equivalent’ when exploring fractions in maths; ‘map’ when discussing story structure in English) the exploration of which has been pivotal to the children’s understanding and, crucially, their capacity to make progress by the end of the lesson. We need to be alert to Tier Two vocabulary – anticipate it when planning – give it attention during teaching. To this end, Jo Dobb and I have created new SBTs for the 18/19 cohort of core Primary and EY PGCE trainees. These tasks will build on work we will do with the students on the ‘taught programme’ to introduce the concept and model the process. We are confident it will have a positive impact on children’s vocabulary development and subsequently (one of my favourite words) on pupil progress. Finally –since we have been thinking about vocabulary development, let me leave you with a topical book recommendation – take a look at ‘What A Wonderful Word’ by Nicola Edwards – a wonderful gift – or indeed why not treat yourself?
