LAUNCHING LITERACY

Teaching Reading Is Rocket Science What Expert Teachers of Reading Should Know and Be Able to Do

By Louisa C. Moats

The most fundamental responsibility of schools is teaching students to read. Because reading affects all other aca- demic achievement and is associated with social, emo- tional, economic, and physical health, it has been the most

researched aspect of human cognition. By the year 2000, after decades of multidisciplinary research, the scientific community had achieved broad consensus regarding these questions: How do children learn to read? What causes reading difficulties? What are the essential components of effective reading instruction and why is each important? How can we prevent or reduce reading difficulties? Two decades later, hundreds of additional studies

have refined and consolidated what we know about bolstering reading achievement, especially for students at risk.

Scientists use increasingly sophisticated technology that can picture the brain’s activation patterns or measure split-second reactions to speech or print. New statistical methods can docu- ment the complicated interactions of many factors as students develop reading skills. Fine-grained analyses illuminate the nature of individual differences and individual responses to instruction. These advanced investigative techniques have con- firmed and extended the bedrock findings about reading and effective teaching of reading that were known 20 years ago. Evi- dence to guide our practices is stronger than it has ever been.

Unfortunately, much of this research is not yet included in teacher preparation programs, widely used curricula, or profes- sional development, so it should come as no surprise that typical classroom practices often deviate substantially from what is rec- ommended by our most credible sources. As a result, reading achievement is not as strong as it should be for most students, and the consequences are particularly dire for students from the least advantaged families and communities.

This we know: reading failure can be prevented in all but a small percentage of children with serious learning disorders. It

is possible to teach most stu- dents how to read if we start early and follow the significant body of research showing which practices are most effective. Stu- dents living in poverty, students of color, and students who are eligible for remedial services can become competent read- ers—at any age. Persistent “gaps” between more advantaged and

less advantaged students can be narrowed and even closed. Fundamentally, these gaps are the result of differences in stu- dents’ opportunities to learn—not their learning abilities.

Although educators have long understood the importance of literacy, teaching children to read is very complex. Far too many children have trouble reading and writing. About 20 percent of elementary school students nationwide have serious problems learning to read; at least another 20 percent are at risk for not meeting grade-level expectations.1 For children growing up in underresourced communities and attending underresourced schools, the incidence of reading failure is astronomical and com- pletely unacceptable. Students who are African American, His- panic, learning English, and/or from impoverished homes fall behind and stay behind in far greater proportion than students who are white and middle class. The rate of weak reading skills in these groups is 60–70 percent, according to the National Assess- ment of Educational Progress.2

The tragedy here is that most reading failure is unnecessary. We now know that classroom teaching itself, when it includes a range of research-based components and practices, can prevent and mitigate reading difficulty. Although home factors do influ- ence how well and how soon students read, informed classroom instruction that targets specific language, cognitive, and reading skills beginning in kindergarten enhances success for all but a very small percentage of students with learning disabilities or severe dyslexia. Researchers now estimate that 95 percent of all children can be taught to read by the end of first grade, with future achievement constrained* only by students’ reasoning and listening comprehension abilities.3

While parents, tutors, and the community can contribute to reading success, classroom instruction is the critical factor in preventing reading problems and must be the primary focus for change.4 To be clear: although the day-to-day work is teachers’ responsibility, students’ reading success is our shared responsibil- ity. From preparation programs to standards and assessments to curricula and professional development, the policies and systems

currently impacting how reading is taught need to improve—dra- matically and rapidly. Teaching reading is rocket science. But it is also established science, with clear, specific, practical instruc- tional strategies that all teachers should be taught and supported in using.

Research-Validated Ideas for Instruction A well-validated concept that should underpin the design of instruction is called the Simple View of Reading.5 It states that reading comprehension is the product of word recognition and language comprehension. Without strong skills in either domain, an individual’s reading comprehension will be compromised.

A reader’s recognition of printed words must be accurate and automatic to support comprehension. The development of auto- matic word recognition depends on intact, proficient phoneme awareness, knowledge of sound-symbol (phoneme-grapheme) correspondences, recognition of print patterns such as recurring letter sequences and syllable spellings, and recognition of mean- ingful parts of words (morphemes).6 Young readers progress by gradually learning each of these ways that our print system represents language, and then applying what they know during ample practice with both oral and silent reading. If reading skill is developing successfully, word recognition gradually becomes

In this report, Louisa C. Moats calls for teacher prepara- tion and professional development to be more rigorous and better aligned with decades of reading science. She describes the knowledge that undergirds successful instruction and concludes with recommendations for the professional preparation of all teachers of reading. It is our nation’s dedicated teachers and their excellent teaching that will bring the rocket science that is research-based reading instruction to classrooms across the country and will unlock the power and joy of reading for our children.

What Expert Teachers of Reading Should Know and Be Able to Do

Policies and systems currently impacting how reading is taught need to improve—dramatically and rapidly.

so fast that it seems as if we are reading “by sight.” The path to that end, however, requires knowing how print represents sounds, syllables, and meaningful word parts; for most students, developing that body of knowledge requires explicit instruction and practice over several grades.7 While some students seem to figure out how the print system works through incidental expo- sure, most do not.

Language comprehension, the other essential domain that underlies reading comprehension, depends on background knowledge, vocabulary, ability to decipher formal and complex sentence patterns, and recognition of the devices that hold a text together.8 Furthermore, language comprehension is facilitated by metacognitive skills such as monitoring whether reading is making sense and choosing to act if it does not. The language comprehension factor in overall reading achievement becomes more and more important from about fourth grade onward.9 From preschool through high school, students gain vital expo- sure to a variety of text forms, language patterns, background knowledge, and vocabulary both by listening to text read aloud and by reading itself.

The implications of the Simple View of Reading should be self- evident: reading and language arts instruction must include deliberate, systematic, and explicit teaching of word recognition and must develop students’ subject-matter knowledge, vocabu- lary, sentence comprehension, and familiarity with the language in written texts. Each of these larger skill domains depends on the integrity of its subskills.

Learning to read is a complex achievement, and learning to teach reading requires extensive knowledge and skills across the components of word recognition, language comprehension, spelling, and writing. Consider what the classroom demands of

the teacher. Children’s interest in reading must be stimulated through regular exposure to interesting books and through discus- sions in which students respond to many kinds of texts. For best results, the teacher must instruct the majority of students directly, systematically, and explicitly to decipher words in print, all the while keeping in mind the ultimate purpose of reading, which is to learn, enjoy, and understand. To accommodate children’s vari- ability, the teacher must assess children and tailor lessons to individuals or groups. This includes interpreting errors, giving corrective feedback, selecting examples to illustrate concepts, explaining new ideas in several ways, and connecting word rec- ognition instruction to meaningful reading and writing.

Some children learn language concepts and their application very easily in spite of incidental teaching, but others never learn unless they are taught in an organized, systematic, efficient way by a knowledgeable teacher using a well-designed instructional approach. Children of average ability might learn enough about reading to get by if their instruction is haphazard; with systematic research-based instruction, those students could achieve much more, such as the appreciation for language structure that sup- ports learning words from context, perceiving subtle differences in meaning, or refining language use.

Toward a Curriculum on the Science of Reading A core curriculum on effective literacy instruction for pre-service and in-service teacher education would, of course, be supple- mented and honed over time, but its goal is to bring continuity, consistency, quality, and comprehensiveness to the many dif- ferent programs, organizations, and systems through which aspiring and current teachers receive information about how to teach reading. Given the current science of reading, this core should be divided roughly into the following four areas:

1. Knowing the basics of reading psychology and development; 2. Understanding language structure for both word recognition

and language comprehension; 3. Applying best practices in all components of reading instruc-

tion; and 4. Using validated, reliable, efficient assessments to inform class-

room teaching.

This excerpt offers an introduction to the first two areas. For a detailed discussion of all four areas, please see the full report: www.aft.org/sites/default/files/Moats.pdf.

1. Reading Psychology and Development

Learning to read is not natural or easy for most children. Unlike spoken language, which is learned with almost any kind of con- textual exposure, reading is an acquired skill. Although surround- ing children with books will support reading development, and a “literature-rich environment” is highly desirable, it is not suffi- cient for learning to read. Neither will exposure to print ordinarily

The word-recognition component of reading is most closely dependent on the phonological aspect of language processing.12 Phonological language skills include awareness of bits of speech or linguistic elements within words: consonant and vowel pho- nemes, spoken syllables, grammatical endings, and meaningful word parts (morphemes). Awareness of these linguistic elements in spoken language is essential for making sense of print because our alphabetic writing system represents language at all these levels. When students cannot rapidly associate the sounds, syl- lables, and/or morphemes in spoken words with printed symbols, they will not be able to store words in their mental dictionaries. Conversely, a new word that is decoded accurately through pho- nological analysis can be pronounced and remembered, even if its meaning is not yet known.

Beginning reading instruction of necessity will focus on teaching students how to read and write words, following a sys- tematic and logical sequence. When appropriate, the emphasis will shift to increasing reading volume. Combining research on reading, cognitive science related to the role of knowledge in thinking, and practice-based wisdom, it appears that oppor- tunities for wide reading are best provided within a knowl- edge-building curriculum in which text readings are linked by a theme or topic.13 Ironically, while background knowledge can be gained from reading, it is also true that those who already know more about a topic make

be sufficient for learning to spell, unless organized practice is provided. Thus, teachers must be reflective, knowledgeable, and intentional about the content they are teaching—that is, the sym- bol system (orthography) itself and its relationship to meaning.

Good readers do not skim and sample the text when they scan a line in a book. They process the letters of each word in detail, although they do so very rapidly and unconsciously. Those who comprehend well accomplish letter-wise text scanning with rela- tive ease and fluency. When word identification is fast and accu- rate, a reader has ample mental energy to think over the meaning of the text. Knowledge of sound-symbol mapping is crucial in developing word recognition: the ability to sound out and recog- nize words accounts for about 80 percent of the variance in first- grade reading comprehension and continues to be a major (albeit diminishing) factor in text comprehension as students progress through the grades (and students’ background knowledge and vocabulary become ever-larger factors in comprehending aca- demic texts).11

The ability to sound out words is, in fact, a major underpinning that allows rapid recognition of words. (This recognition is so fast that some people mistakenly believe it is happening “by sight.”) Before children can easily sound out or decode words, they must have at least an implicit awareness of the speech sounds that are represented by symbolic units (letters and their combinations). Children who learn to read well are sensitive to linguistic struc- ture, recognize redundant patterns, and connect letter patterns with sounds, syllables, and meaningful word parts quickly, accu- rately, and unconsciously. Effective teaching of reading entails these concepts, presenting them in a sequence from simple and consistent to complex and variable.

Teachers are often not in a position to make decisions regarding school district reading curricula and/or reading texts. Nevertheless, teachers who understand the foundations of reading psychology and development will be better prepared to argue against the adoption of irresponsible fads and countermand the proliferation of appealing but unsup- ported ideas. Examples of enduring myths and misconceptions that are embedded in popular programs, articles, and text- books10 include:

• reading instruction is only needed until third grade;

• competent teachers do not use

published reading programs; • avoiding published reading programs

empowers teachers and enhances the professional status of teaching;

• teaching phonics, word attack, and spelling skills directly to children is harmful;

• reading a lot is the best way to overcome a reading problem;

• children should be taught to guess words on the basis of meaning and syntax; and

• skills must always be taught in the context of literature.

With no accountability system to check their dissemination, unsupported

ideas such as these fill the void left by weak pre-service and in-service programs. Perhaps the dubious quality of past educational research has justified the prevalent cynicism among educators, who are often told that research exists to support any point of view. However, reading is actually one of the most studied aspects of human behavior, and a large body of work based on sound principles of objective inquiry exists that could be informing the field. Converging findings from multiple studies, like those summarized in this article, should drive the profession.

better inferences and retain meanings better than those who know little about it. Therefore, reading practice should be linked to or embedded within the study of subjects including science, history, literature, and the arts. Interpretive strategies that facili- tate comprehension—including summarizing, questioning, predicting outcomes, and monitoring one’s own understand- ing—are best used in the service of learning defined curricular

content.14 Moreover, writing in response to reading is one of the best ways to enhance reading comprehension.15

2. Language Structure

Expert teaching of reading requires knowledge of language structure at all levels.16 Without such knowledge, teachers are not able to respond insightfully to student errors, choose exam-

Learning to teach reading requires extensive knowledge and skills of word recognition, language comprehension, spelling, and writing.

Selected Concepts and Skills by Domain Ideas for Application to Instruction

1. Phonetics and Phonology Understand that speech sounds are not letters, and letters do not make sounds— they represent them.

Know that consonant and vowel phonemes can be grouped into classes with similar properties (e.g., stops, nasals, etc.).

Instead of asking “What sound does each letter make?,” use accurate language and focus on a specific sound, asking, “What letter(s) represent /er/ in first?”

Help children focus on sounds by saying things like, “/m/, /n/, and /ng/ are the three ‘nosey’ sounds in English; hold your nose to feel how these sounds go through the nose.”

2. Phoneme Awareness Produce speech sounds accurately during reading, vocabulary, and spelling instruction.

Identify, match, and select appropriate examples of words containing specific phonemes.

Say /t/ crisply, not tuh.

In teaching awareness of the phoneme /sh/, use words including shoe, chef, and sugar. (Listen for the sound; don’t confuse the task with spelling or phonics.)

3. Morphology Identify morphemes (the smallest meaningful units of language) and distinguish them from syllables.

Recognize that spellings of morphemes are often stable even when pronunciation varies in words with a common root; as a result, spelling can be a clue to meaning.

The word interchangeable has five syllables and three morphemes: inter, change, able.

Express, expression; legal, legislate; inspire, inspiration; nature, natural.

4. Orthography Understand that letters and letter combinations (graphemes) represent sounds but are not the same as sounds.

Use a comprehensive scope and sequence that includes instruction in digraphs, blends, silent letter combinations, vowel teams, diphthongs, and the six common syllable types.

The phoneme /f/ is represented by f, ff (stuff), gh (tough), and ph (phone).

Explicit instruction in the written code should extend at least through grade 3 when syllables and morphemes in longer words are tackled.

5. Semantics Teach word meanings in relation to other word meanings.

Adopt a routine for teaching unfamiliar word meanings to students.

Include antonyms, synonyms, associations, analogies, and categorical relationships on vocabulary tasks.

Provide a student-friendly definition, many examples, and opportunities for students to say and use new words.

6. Syntax and Text Structure Appreciate that texts have structures that can be represented with graphic organizers (e.g., narrative and informational texts organized as compare/ contrast, argumentation, description, cause/effect, etc.).

Identify cohesive devices such as pronoun references, connecting words, word substitutions, parallel sentence structure, and paragraph organization.

Identify and illustrate for students the purpose of a given text and its logical structure.

Help students identify how a text hangs together and how to follow the connections among ideas as meaning is constructed.

Examples of Knowledge of Language Structure and Their Application to Teaching

ples for concepts, explain and contrast words and their parts, or judge what focus is needed in a lesson. The table on page 8 pro- vides examples of key concepts of language structure and how they apply to instruction.

Experts agree that children who initially are at risk for fail- ure are saved, in most cases, by instruction that directly teaches the specific foundational language skills on which proficient reading depends.17 Effective teachers of

reading raise awareness and proficiency through every layer of language organization, including sounds, syllables, meaningful parts (morphemes), phrases, sentences, paragraphs, and various genres of text. Their teaching strategies are explicit, systematic, and engaging.18 They also balance language skill instruction with its application to purposeful daily writing and reading, no matter what the skill level of the learner. Middle- and upper-grade chil- dren who are weak readers can be brought up to grade level with appropriate instruction (although the time, effort, and emo- tional strain for children and teachers involved is considerably greater than that required to teach younger children, so offering research-based instruction in the early grades must remain a top priority).

A rich and meaningful curriculum, in which students are exposed to a variety of texts as they learn concepts in science, litera- ture, social studies, history, the arts, and culture, should provide the context for developing reading and writing skills. Comprehen- sion strategies should not be taught in isolation but used as neces- sary to enhance understanding of text assigned for content learning. Useful comprehension strategies to embed in content reading include prediction of outcomes, summarizing, clarification, ques- tioning, and visualization; these can be modeled explicitly by the

teacher and practiced overtly if students are not comprehending well or if they approach reading comprehension passively. Vocabu- lary is best taught with a variety of complementary methods, both direct and incidental, designed to explore the relationships among words and the relationships among word structure, origin, and meaning. Of course, children also benefit from access to full librar- ies and incentives to read independently.

The fact that teachers need better preparation, professional development, and resources to carry out deliberate instruction in reading, spelling, and writing should prompt action rather than criticism. It should highlight the chronic gap between what teachers need and what they have been given. Just about all children can be taught to read and deserve no less from their teachers. Teachers, in turn, deserve no less than the knowledge, skills, and supported practice that will enable their teaching to succeed. There is no more important challenge for education to undertake. ☐
