1 | Discriminating sounds and phonemes |
Learning outcomes
This chapter will help you to audit your:
ā¢ understanding of key terminology;
ā¢ appreciation of the difficulties faced by adults and advanced readers in being able to discriminate phonemes and ways of overcoming them;
ā¢ understanding of different methods of checking phonemic awareness.
Work through each section below, responding to each question or task. When you have completed each section, you can read the answers at the end of the chapter. At the end of this chapter you can also find support for further reading and study related to discriminating sounds and phonemes.
Section 1: key terminology for discriminating sounds and phonemes
It is important that you understand the terms below before you move on to the next activity. Provide a definition of each and check your definitions against those given later in this chapter:
ā¢ phonemes
ā¢ graphemes
ā¢ phonological awareness
ā¢ phonemic awareness
ā¢ segmentation and blending
ā¢ adjacent consonants
Section 2: segmenting words
Test your knowledge by trying to work out the number of phonemes in the words below. Remember that there are always the same number of phonemes as graphemes, as a grapheme can be any number of letters that represent that phoneme.
Remember:
ā¢ in ābatā we can hear 3 phonemes: b/ a/ t/
ā¢ in āshipā we can hear 3 phonemes: sh/ i/ p/
ā¢ In ānightā we can hear 3 phonemes: n/ igh/ t/
Section 3: phoneme frames
In schools, many teachers use phoneme frames to help children to segment words into phonemes and graphemes. For example:
Use the frame below to segment the following words: blow, shortly, blast, window, draining:
Answers
Section 1: key terminology for discriminating sounds and phonemes
Phonemes
Phonemes are individual sounds. In English, there are around 44 phonemes (the number varies slightly according to accent and which phonics programme you look at).
Graphemes
Graphemes are phonemes written down, so in the word cat there are three phonemes and they are represented by three graphemes /c/a/t/. In the word shop there are three phonemes but the first is represented by two letters making one sound (a digraph):/sh/o/p/.
Phonological awareness
Phonological awareness involves being able to hear, recall and manipulate sounds.
Phonemic awareness
Phonemic awareness is the ability to hear and manipulate the phonemes in spoken words and to remember the order of phonemes in words. For example, the phonemes in the word big can be segmented as /b/ /i/ /g/.
Segmentation and blending
Oral blending and segmentation, which are the reverse of each other, help children to blend and segment for reading and spelling when they learn letters and sounds.
Adjacent consonants
Consonants which are side by side but have separate phonemes ā for example, s/t in stop, c/l in club and s/t/r in strip. Although we blend these sounds together, it is important to emphasise that the letters each have individual sounds.
Section 2: segmenting words
If you managed to segment all the words correctly, well done! If you didnāt you may have struggled because you are already a sophisticated reader who doesnāt always pay attention to every sound in a word. For example, you may have segmented stress as str/e/ss/ because you are used to seeing str in words and assume that this is a single sound. In fact, str is three sounds. Try saying the letter sounds slowly and notice what happens in your mouth: you make three different shapes ā one for each letter sound or phoneme.
You may similarly have decided that crash should be segmented as cr/a/sh/ because you are familiar with words which begin with cr (crack, crumb, cricket). Again, try sounding the phonemes slowly and you will notice that your mouth makes two shapes as you do so. These groups of letters which occur frequently in words are called consonant clusters or consonant blends and more recently adjacent consonants. It is very useful for readers to be aware of them as their reading develops, but beginner readers need to be able to identify every sound in new words if they are to be able to say them correctly and then spell them accurately.
Section 3: phoneme frames
How did you manage this time? In the first word, blow, there are three phonemes and you needed not only to realise that bl represents two sounds, but also that ow represents a single sound which is represented by two letters: a digraph. Try saying ow, making the same sound as in blow. Notice that your mouth stays open throughout, which is a feature of vowel phonemes:
ā¢ In shortly, sh represents a single sound and both letters are consonants, so sh is a consonant digraph. The or part of the word is a single sound and even though r is a consonant the sound is a vowel sound, so or is referred to as a vowel digraph.
ā¢ Blast has five sounds, although the bl at the beginning and st at the end are consonant clusters, but each represents two sounds.
ā¢ Window has a vowel digraph at the end (ow) ā notice that your mouth remains open as you make the sound.
ā¢ Draining includes the vowel digraph ai, which you probably spotted, but did you decide that the ng at the end was one sound or two? For most English-speakers ng is a single sound, but for some, particularly in parts of the English Midlands and some areas in Yorkshire, ng can be sounded as two sounds. Phonics programmes tend to regard ng as a single sound.
The split vowel digraph
In Chapter 5 you will look at words in which the vowel sound is made by two letters which are not immediately adjacent to each other (as in make, safe, bite etc.).
What to do next?
Reinforce your knowledge and understanding of segmenting by doing as many as possible of the following:
ā¢ Observe teachers working with children and note how they model segmenting. How do they show children how to count phonemes?
ā¢ Read Chapter 1 in Teaching Systematic Synthetic Phonics in Primary Schools (Jolliffe et al., 2012) to find out more about blending and segmenting.
ā¢ Practise with a colleague segmenting the follo...
