Learning About Phonemes |
| The level of a student's phonological awareness is a strong predictor of his or her future reading achievement (Juel, 1991; Scarborough, 1989; Stanovich, 1986, Wagner, Torgesen, & Rashotte, 1994). Good phonological awareness leads to better reading and spelling. Struggling readers, from kindergarten to adulthood, consistently have been found to have poor phonological awareness that can be strengthened through intensive, systematic instruction. Teachers who are explicit in helping struggling readers attend to the unique characteristics of individual phonemes have been able to not only significantly increase these students' phonological awareness but have also been able to reduce the number of students who end up with severe reading disabilities (e.g., Torgesen, Wagner, & Rashotte, 1997; Truch, 1994). | ||
| The purpose of this lesson is to begin to develop your knowledge about phonemes. Learning about phonemes will help you be able to provide the type of intensive, explicit instruction which struggling readers require. This knowledge will help you develop appropriate instructional sequences and choose suitable examples for teaching decoding and spelling as well as help you interpret and respond to students' errors (Moats, 1995b). | ||
| At the end of this lesson you should be able to do three things. You should be able to describe the unique characteristics of each of the 39 phonemes. You should be able to enunciate each phoneme clearly. And, you should be working toward a high rate of accuracy in identifying the specific phonemes in spoken words. To achieve this last goal, you may need to repeat portions of this lesson. | ||
| The focus of this lesson is on one of the most important elements of phonological awareness which is phonemic awareness. If a phoneme is the smallest speech sound, then phonemic awareness is the insight that every spoken word is composed of individual phonemes in a specific sequence (Committee on the Prevention of Reading Difficulties in Young Children, 1998). In the word 'sun', the three phonemes in sequence are |s| |u| |n|. By understanding that spoken words are made up of these speech sounds, beginning readers can begin to develop the understanding that the letters of the alphabet represent the individual speech sounds in words. That is, |s| is represented by the letter 's', |u| is represented by the letter 'u', and |n| is represented by the letter 'n'. By first being aware of phonemes and then learning how they relate to letters, struggling readers can more easily make the connections between the words they hear and the words they see on a page. This knowledge is absolutely essential for students to be able to begin sounding out and reading words. We know that at least 25% of middle class first-graders and even larger numbers of diverse students have difficulty grasping these concepts without explicit, systematic instruction (See Adams, 1990, for a review). | ||
| O.K., are you ready to test yourself on your own phonemic awareness? Let's begin. How many phonemes are in the word 'cat', and what are they? | ||
| If you said there are three phonemes, you are right. The three phonemes are |k| |a| |t|. | ||
| Let's try another one. How many phonemes do you hear in the word 'king', and what are they? | ||
| Ready? Let's begin by looking at the consonants. The consonant phonemes are grouped in several different ways. One useful way to think about the consonants is in terms of whether they are continuous or stop-like sounds. Continuous sounds are sounds that you can continue to say in the same way until you run out of breath. For instance, |m| is a continuous sound because you can say it until you run out of breath. Say the |m| sound until you run out of breath. You can do that with each of the continuous sounds. When talking to students about these sounds, some teachers refer to them as the 'sounds that go'. Repeat after me as I say each of the continuous sounds that are listed from left to right on your screen. As you say the sounds, pay attention to how your mouth, teeth, lips and tongue do different things to say each sound. Ready? |m|, |n|, |ng|, |f|, |th| as in thumb, |s|, |sh|, |h|, |v|, |TH| as in this, |z|, |zh| as in measure, |l| and finally |r|. Good. | ||
| Blending is taking individual phonemes and saying them at a fast enough rate, without pausing between the sounds, so that the sounds make a word. If a student was asked to blend the three phonemes |m|, |a|, |n|, the child might say the sounds several times at faster and faster rates until he or she says a real word. |mmmmmmmm|aaaaaaaaa|nnnnnnn| |mmm|aaaa|nnnnn| |man|. With a continuous sound at the beginning of the word this task is relatively simple. But, having a stop sound at the beginning of the word makes it harder for beginning readers because you can not sustain a stop sound. With the stop sound of |k| at the beginning of the word, trying to blend the three sounds |k| |a| |n| would sound like this: |k| |aaaaaa|nnnnnn| , |k| |aaaa|nnnn|, |k| |an| , |k| an|. As you could hear, the stop sound at the beginning of this word made blending these sounds much harder than blending the sounds in the first example that had a continuous sound at the beginning of the word. Once students know how to blend, it would then be appropriate to introduce stop sounds at the ending and then the beginning of words. In the next lesson and the next module, you will learn more about choosing appropriate words for practice in reading. | ||
| Besides categorizing sounds as stop or go sounds, other categories can be used to refer to the way sounds are produced. For example, three of the consonant phonemes are considered to be nasals or nose sounds. When you make these sounds, your nose vibrates because the air is being forced out of the nose instead of the mouth. These sounds are |m|, |n|, and the 'n' 'g' sound |ng| as in ring. Hold your nose closed and try to say each of the sounds. Say |m|, now say |n|, now say |ng|. Did you feel the air being forced into your nose? Try each sound again but this time place your fingers on the bridge of your nose to feel the vibrations when you say these sounds. Say |m|, say |n|, say |ng|. | ||
| There are also nine sounds that are called fricatives. We will call these hissers because that is a word that students understand. The hissers force air through a very small opening between the top teeth and the tongue or lip, or the roof of the mouth and tongue. These 'hissing' sounds are |f|, |th| as in thumb, |s|, |sh|, |v|, |TH| as in this, |z|, and |zh| as in measure. Most of the fricatives are late developing speech sounds for children and there are two different times that they will tend to get these sounds mixed up. The first time is when they are just learning to speak and the second time is when they are beginning to learn to read and spell. Knowing this can help you look for indications of this confusion. | ||
| The consonant phonemes |l| and |r| are called liquids. When you say the liquid sounds you can almost imagine liquid being poured from a pitcher into a glass because the sounds just flow like a liquid. Say these two liquids. Say |l|, now say |r|. For those of you who will be working with young children, it is important that you know that developmentally it is normal for some children to have difficulty saying |r| and |l| until they reach the age of seven or eight. | ||
| The two sounds of |ch| and |j| are classified as scratcher sounds when working with your students. Say |ch|, say |j|. | ||
| The glide sounds require the tongue, lips and teeth to glide into position to make the sounds. The glides are the 'y' sound which is |y|, and the 'w' sound which is |w|. Try each one and feel your mouth "gliding" when you say it. Say |y| as in yes, and say |w| as in win. Although these sounds are not officially considered stop sounds, because you can't sustain them unless you add a vowel sound to them, they have been placed next to the stop sounds on your chart. This is to remind you that when you're teaching the blending of sounds and letters, it would be better to wait to use these sounds until students are proficient with blending continuous sounds in the initial and final positions in words. | ||
|
Another way that phonemes are described is by their voicing. Voicing refers to whether sounds are whispered or spoken. Consonants are either voiced or voiceless. When consonants are voiced, the vocal folds vibrate together to make the sound. Put your hand on your throat and see if you can feel your larynx vibrating when you make the sound |v|. Try it, |v|. Did you feel the vibrations? That means that the vocal folds are vibrating together to make the sound voiced. Most of the consonants and all of the vowels are voiced. There are, however, nine voiceless consonants. The voiceless consonants are whispered. In making these sounds, the vocal folds are separated and there is no vibration, so the sounds come out quiet or voiceless. Check your throat to see if it vibrates when you say the sound |f|. Try it. There should have been no vibrations and therefore the sound was voiceless or quiet. Now, what can be very confusing to beginning readers and spellers is that there are pairs of consonant phonemes that are produced in exactly the same way but differ only in their voicing. Each of the stop sounds, the affricates or scratchers and all but one of the fricatives or hisser sounds have a partner sound. The only voiceless consonant without a partner is the |h| sound. Say |f|; now say its partner |v|. Did you notice that you said them in exactly the same way except that the |v| was voiced and the |f| was voiceless? | ||
| Looking at your chart, the unvoiced sounds are in regular type. We'll be practicing the voiced and unvoiced pairs so that you can notice how each partner is pronounced in exactly the same way with the only difference being in the voicing. We'll start with the hisser sounds and then drop down to the scratcher sounds. Starting on the left, the voiced pairs are: |f| |v|, |th| (as in 'thumb') and |TH| (as in 'this'), |s|, |z|, and |sh| and |zh| (as in 'measure'). Going down to the scratcher sounds, that pair is |ch| and |j|. Good. | ||
| As you look at the chart on your screen, you can see that most of the vowel phonemes are organized into the shape of the letter 'u'; this is called the vowel circle map that can be used with young as well as more mature readers. This particular chart is an adaptation of the different vowel charts that were developed by two reading experts, Pat Lindamood and Louisa Moats. One of the challenges with teaching about vowel phonemes is that, unlike the consonant phonemes, the vowel phonemes have fewer contrasting features to help distinguish one from the other. With the vowel phonemes that are listed on the vowel circle, it's the combination of slight movements of the tongue and the relatively minor changes of the shapes of the lips from one vowel to the next that differentiates these phonemes. The little faces on the chart show that as the phonemes are pronounced in order, the mouth changes shape from a wide smile to a rounded pucker shape. As we go through these sounds, you will begin to understand why it is sometimes so difficult to distinguish one vowel sound from another. Starting at the left side of the chart, the vowel phonemes are |E|, |i|, |A|, |e|, |a|, |o|, |aw|, |O|, |oo| as in book, and |OO| as in school. | ||
| To help you learn to say these vowel phonemes, and to show you a way to help your students learn them in order, we will use a few different methods. First, to help you learn to say the phonemes accurately, I'll say each mnemonic device and the phoneme chart. | ||
| O.K., let's add the other vowel phonemes. Looking at the |er| and the |u| phonemes, the words are, "Her fun!" and moving down to the vowel diphthongs, the silly sentence is, "Boy, I'm grounded!" | ||
| Now that you are almost done with this basic lesson on phonemes, we'll do a quick review and a posttest. | ||

As you learned in the introductory module, part of good instruction includes helping students assess their own gains in knowledge. To do the review, we'll look at the original goals of this lesson. The first goal was for you to be able to describe the unique characteristics of each of the 39 phonemes. At this point you should be able to explain the differences between phonemes classified as continuous, stop, nasal, liquids, glides, hissers, and scratchers. You should also be able to explain the difference between voiced and unvoiced sounds as well as where the different sounds are produced in the mouth. You should be able to say the sounds for the 10 vowel phonemes on the vowel circle, the phonemes in the middle of the circle and the three vowel diphthongs. If you can do this, you should be able to explicitly teach about and help your students feel the differences between the phonemes. Being able to do this can help struggling readers of all ages become better readers and spellers. Specific examples of how to incorporate this knowledge into your instruction will be given in later lessons in this module and the module on advanced word reading.
The second goal was for you to learn to enunciate each phoneme clearly. Hopefully you took the practice opportunities. As you are working with students, keep in mind that because we have quite a few different dialects in the English language, not all students will pronounce the phonemes in the same way. This is especially true for the vowel phonemes. It is important however that you as a teacher try to pronounce them as clearly and accurately as possible and try to have your students practice them in this way also. The last goal was for you to be able to more accurately identify the specific phonemes in spoken words. In order for you to test yourself, we have developed an activity in which you are shown written words and then you indicate the number of phonemes you believe are in the word. The correct answers are given as well. At the beginning of this lesson, you may have wondered if there was very much to learn about phonemes. Hopefully you have learned that there is. One of the advantages of going through a lesson like this on the computer is that you can repeat it any time that you find you have a need for more practice. After having gone through this lesson, Learning About Phonemes, you will now have the background knowledge that is necessary to be able to effectively apply the instructional interventions that are presented in the following lessons on teaching students beginning reading and spelling skills. If you are interested in studying phonemes and phonology in more depth, you may want to take a course in the speech-language or linguistics departments at a local college or receive some training in a reading program that places great emphasis on phonemic knowledge. | ||
