Reading 101: What Parents and Teachers Should Know About (Part III)

Phonics Instruction
By: National Reading Panel (2000)

Phonics instruction is a way of teaching reading that stresses the acquisition of letter-sound correspondences and their use in reading and spelling.
The primary focus of phonics instruction is to help beginning readers understand how letters are linked to sounds (phonemes) to form letter-sound correspondences and spelling patterns and to help them learn how to apply this knowledge in their reading.

Phonics instruction may be provided systematically or incidentally. The hallmark of a systematic phonics approach or program is that a sequential set of phonics elements is delineated and these elements are taught along a dimension of explicitness depending on the type of phonics method employed. Conversely, with incidental phonics instruction, the teacher does not follow a planned sequence of phonics elements to guide instruction but highlights particular elements opportunistically when they appear in text.


Types of phonics instructional methods and approaches

This depicts several different types of phonics instructional approaches that vary according to the unit of analysis or how letter-sound combinations are represented to the student. For example, in synthetic phonics approaches, students are taught to link an individual letter or letter combination with its appropriate sound and then blend the sounds to form words. In analytic phonics, students are first taught whole word units followed by systematic instruction linking the specific letters in the word with their respective sounds.

Phonics instruction can also vary with respect to the explicitness by which the phonic elements are taught and practiced in the reading of text. For example, many synthetic phonics approaches use direct instruction in teaching phonics components and provide opportunities for applying these skills in decodable text formats characterized by a controlled vocabulary. On the other hand, embedded phonics approaches are typically less explicit and use decodable text for practice less frequently, although the phonics concepts to be learned can still be presented systematically.

Analogy phonics
Teaching students unfamiliar words by analogy to known words (e.g., recognizing that the rime segment of an unfamiliar word is identical to that of a familiar word, and then blending the known rime with the new word onset, such as reading brick by recognizing that -ick is contained in the known word kick, or reading stump by analogy to jump).

Analytic phonics
Teaching students to analyze letter-sound relations in previously learned words to avoid pronouncing sounds in isolation.

Embedded phonics
Teaching students phonics skills by embedding phonics instruction in text reading, a more implicit approach that relies to some extent on incidental learning.

Phonics through spelling
Teaching students to segment words into phonemes and to select letters for those phonemes (i.e., teaching students to spell words phonemically).

Synthetic phonics
Teaching students explicitly to convert letters into sounds (phonemes) and then blend the sounds to form recognizable words.


Findings and determinations

The meta-analysis revealed that systematic phonics instruction produces significant benefits for students in kindergarten through 6th grade and for children having difficulty learning to read. The ability to read and spell words was enhanced in kindergartners who received systematic beginning phonics instruction. First graders who were taught phonics systematically were better able to decode and spell, and they showed significant improvement in their ability to comprehend text. Older children receiving phonics instruction were better able to decode and spell words and to read text orally, but their comprehension of text was not significantly improved.

Systematic synthetic phonics instruction (see table for definition) had a positive and significant effect on disabled readers' reading skills. These children improved substantially in their ability to read words and showed significant, albeit small, gains in their ability to process text as a result of systematic synthetic phonics instruction. This type of phonics instruction benefits both students with learning disabilities and low-achieving students who are not disabled. Moreover, systematic synthetic phonics instruction was significantly more effective in improving low socioeconomic status (SES) children's alphabetic knowledge and word reading skills than instructional approaches that were less focused on these initial reading skills.

Across all grade levels, systematic phonics instruction improved the ability of good readers to spell. The impact was strongest for kindergartners and decreased in later grades. For poor readers, the impact of phonics instruction on spelling was small, perhaps reflecting the consistent finding that disabled readers have trouble learning to spell.

Although conventional wisdom has suggested that kindergarten students might not be ready for phonics instruction, this assumption was not supported by the data. The effects of systematic early phonics instruction were significant and substantial in kindergarten and the 1st grade, indicating that systematic phonics programs should be implemented at those age and grade levels.


Discussion


These facts and findings provide converging evidence that explicit, systematic phonics instruction is a valuable and essential part of a successful classroom reading program. However, there is a need to be cautious in giving a blanket endorsement of all kinds of phonics instruction.

It is important to recognize that the goals of phonics instruction are to provide children with key knowledge and skills and to ensure that they know how to apply that knowledge in their reading and writing. In other words, phonics teaching is a means to an end.

To be able to make use of letter-sound information, children need phonemic awareness. That is, they need to be able to blend sounds together to decode words, and they need to break spoken words into their constituent sounds to write words. Programs that focus too much on the teaching of letter-sound relations and not enough on putting them to use are unlikely to be very effective.

In implementing systematic phonics instruction, educators must keep the end in mind and ensure that children understand the purpose of learning letter sounds and that they are able to apply these skills accurately and fluently in their daily reading and writing activities.

Teachers should be able to assess the needs of the individual students and tailor instruction to meet specific needs. However, it is more common for phonics programs to present a fixed sequence of lessons scheduled from the beginning to the end of the school year. In light of this, teachers need to be flexible in their phonics instruction in order to adapt it to individual student needs.

Children who have already developed phonics skills and can apply them appropriately in the reading process do not require the same level and intensity of phonics instruction provided to children at the initial phases of reading acquisition. Teachers must understand that systematic phonics instruction is only one component – albeit a necessary component – of a total reading program; systematic phonics instruction should be integrated with other reading instruction in phonemic awareness, fluency, and comprehension strategies to create a complete reading program.

It is important not to judge children's reading competence solely on the basis of their phonics skills and not to devalue their interest in books because they cannot decode with complete accuracy. It is also critical for teachers to understand that systematic phonics instruction can be provided in an entertaining, vibrant, and creative manner.

Systematic phonics instruction is designed to increase accuracy in decoding and word recognition skills, which in turn facilitate comprehension. However, it is again important to note that fluent and automatic application of phonics skills to text is another critical skill that must be taught and learned to maximize oral reading and reading comprehension. This issue again underscores the need for teachers to understand that while phonics skills are necessary in order to learn to read, they are not sufficient in their own right. Phonics skills must be integrated with the development of phonemic awareness, fluency, and text reading comprehension skills.

Reading 101: What Parents and Teachers Should Know About (Part 2 of Six Parts)


The Alphabetic Principle

Children's knowledge of letter names and shapes is a strong predictor of their success in learning to read. Knowing letter names is strongly related to children's ability to remember the forms of written words and their ability to treat words as sequences of letters.

Not knowing letter names is related to children's difficulty in learning letter sounds and in recognizing words. Children cannot understand and apply the alphabetic principle (understanding that there are systematic and predictable relationships between written letters and spoken sounds) until they can recognize and name a number of letters.

Children whose alphabetic knowledge is not well developed when they start school need sensibly organized instruction that will help them identify, name, and write letters. Once children are able to identify and name letters with ease, they can begin to learn letter sounds and spellings. Children appear to acquire alphabetic knowledge in a sequence that begins with letter names, then letter shapes, and finally letter sounds. Children learn letter names by singing songs such as the "Alphabet Song," and by reciting rhymes. They learn letter shapes as they play with blocks, plastic letters, and alphabetic books. Informal but planned instruction in which children have many opportunities to see, play with, and compare letters leads to efficient letter learning. This instruction should include activities in which children learn to identify, name, and write both upper case and lower case versions of each letter.

What is the "Alphabetic Principle"?

Children's reading development is dependent on their understanding of the alphabetic principle – the idea that letters and letter patterns represent the sounds of spoken language. Learning that there are predictable relationships between sounds and letters allows children to apply these relationships to both familiar and unfamiliar words, and to begin to read with fluency.

The goal of phonics instruction is to help children to learn and be able to use the Alphabetic Principle. The alphabetic principle is the understanding that there are systematic and predictable relationships between written letters and spoken sounds. Phonics instruction helps children learn the relationships between the letters of written language and the sounds of spoken language.

Two issues of importance in instruction in the alphabetic principle are the plan of instruction and the rate of instruction.

The Alphabetic Principle Plan of Instruction

  • Teach letter-sound relationships explicitly and in isolation.
  • Provide opportunities for children to practice letter-sound relationships in daily lessons.
  • Provide practice opportunities that include new sound-letter relationships, as well as cumulatively reviewing previously taught relationships.
  • Give children opportunities early and often to apply their expanding knowledge of sound-letter relationships to the reading of phonetically spelled words that are familiar in meaning.

Rate and Sequence of Instruction

No set rule governs how fast or how slow to introduce letter-sound relationships. One obvious and important factor to consider in determining the rate of introduction is the performance of the group of students with whom the instruction is to be used. Furthermore, there is no agreed upon order in which to introduce the letter-sound relationships. It is generally agreed, however, that the earliest relationships introduced should be those that enable children to begin reading words as soon as possible. That is, the relationships chosen should have high utility. For example, the spellings m, a, t, s, p, and h are high utility, but the spellings x as in box, gh, as in through, ey as in they, and a as in want are of lower utility.

It is also a good idea to begin instruction in sound-letter relationships by choosing consonants such as f, m, n, r, and s, whose sounds can be pronounced in isolation with the least distortion. Stop sounds at the beginning or middle of words are harder for children to blend than are continuous sounds.

Instruction should also separate the introduction of sounds for letters that are confusing to hear, such as /b/ and /v/ or /i/ and /e/, or visually confusing, such as b and d or p and g.

Instruction might start by introducing two or more single consonants and one or two short vowel sounds. It can then add more single consonants and more short vowel sounds, with perhaps one long vowel sound. It might next add consonant blends, followed by digraphs (for example, th, sh, ch), which permits children to read common words such as this, she, and chair. Introducing single consonants and consonant blends or clusters should be introduced in separate lessons to avoid confusion.

The point is that the order of introduction should be logical and consistent with the rate at which children can learn. Furthermore, the sound-letter relationships chosen for early introduction should permit children to work with words as soon as possible.

Many teachers use a combination of instructional methods rather than just one. Research suggests that explicit, teacher-directed instruction is more effective in teaching the alphabetic principle than is less-explicit and less-direct instruction.

Guidelines for Rate and Sequence of Instruction
  • Recognize that children learn sound-letter relationships at different rates.
  • Introduce sound-letter relationships at a reasonable pace, in a range from two to four letter-sound relationships a week.
  • Teach high-utility letter-sound relationships early.
  • Introduce consonants and vowels in a sequence that permits the children to read words quickly.
  • Avoid the simultaneous introduction of auditory or visually similar sounds and letters
  • Introduce single consonant sounds and consonant blends/clusters in separate lessons.
  • Provide blending instruction with words that contain the letter-sound relationships that children have learned.
