They add precision by providing new ways to express concepts that are already understood. Tier 2 words are essential for building formal academic language and they add precision and sophistication to texts. They usually have multiple meanings based on the context they are used in. They appear more frequently in texts than in oral language, so children are less likely to learn them without engaging with texts. Tier 2 words occur across a variety of domains and subjects. The final tier for consideration is perhaps the most important but often the overlooked tier. These are examples of Tier 3 words from the text. This is dangerous for both the animals and residents.” The words 'residential' and 'residents' have specific meanings to do with location of living. The final bullet point says “Feeding animals can encourage them to look for food in residential areas or nearby farms. In general, we learn these words when there is a specific need. Some examples of Tier 3 words might be 'Pantheon', 'diameter' and 'epidermis'. They are often limited to specific topics and domains, and Tier 3 words are likely to be new for all students so they can represent a level playing field for all students. This set of words has a low frequency of use in everyday conversation. We can consider this text from the 2016 NAPLAN Year 5 and 7 Reading Magazine called ‘Please do not feed native animals.’ The first paragraph says "You might think that you are being kind to the native birds and animals by giving them your food scraps, but feeding them or leaving rubbish around that they might eat is cruel, not kind!" We can identify lots of Tier 1 words in this paragraph: 'think', 'kind', 'giving' and 'food' are all examples of Tier 1 words. Tier 1 words will continue to be acquired from everyday life including through school life. Some examples are 'small', 'big' or 'walk'. They do not usually require explicit instruction, however, where they do, particularly for students learning Standard Australian English, they are easily explained and understood, as they are highly concrete nouns, verbs and adjectives. Tier 1 words are the common, everyday words that most children enter school knowing already – either in English or their first language. Isabel Beck’s distinction between the three types or tiers of vocabulary is very helpful in making choices about specific vocabulary to teach. The framework groups words starting from those that are most common in Tier 1 to those that are more specific in Tier 3. The three-tier model of vocabulary development, described by Beck, McKeown, and Kucan (2013) is a framework to classify words. Watch Dr Deslea Konza speak about vocabulary. As children learn to read more advanced texts, they must learn the meaning of new words that are not part of their oral vocabulary.ĭr Deslea Konza says that the number and variety of words that children know in the preschool and initial years of schooling, is a significant predictor of reading comprehension in the middle and secondary years of schooling and of broader academic and vocational success. Readers cannot understand what they are reading without knowing what most of the words mean. Vocabulary is also the key to reading comprehension. This also supports them to read related words. A student is more likely to be able to read a word if they find a match between the word on the page and a word they have learnt through listening and speaking. Vocabulary plays an important role in word recognition. Why is vocabulary important for reading instruction? The words we need to know to understand what we read. Reading vocabulary refers to words we recognise or use in print. It is the knowledge of words and word meanings. Vocabulary refers to the words we must know and understand to communicate effectively.
