The Simple View of Reading was first proposed by Gough and Tunmer in 1986 and is one of the most supported models of reading to date. The gist of the Simple View is that Reading Comprehension (RC) is the product of Decoding (D) and Linguistic (or Language) Comprehension (LC).
RC is the *product* of D and LC because if either decoding or language comprehension equals zero, the end result (reading comprehension) is zero. For example, if I can decode Spanish (pronouncing the words on the page accurately) but don’t understand a word of it, I won’t comprehend it. And, if a child can understand simple spoken English (my 2 year old) but can’t decode printed words on the page stating the same, she won’t have any reading comprehension (because she can’t read yet).
This theory, now supported by decades of empirical research, is the basis for how we can understand reading development, instruction, and assessment. Sometimes, a lack of training in the Simple View causes well-meaning professionals to conflate decoding with comprehension at the expense of valuable instructional time.
This is sometimes seen in the field when we ask students, who have yet to learn the code, to “read for meaning” in kindergarten; predictable books are given to students sitting around a kidney shaped table so they can “read” them based on the pattern and the pictures. This misconception is also seen when professionals state that sounding out words can “get in the way of making meaning.” More accurately, decoding is the way kids *access the language* underneath the printed text (or code).
A child entering kindergarten already knows what a horse, a cow, and a sheep look like; however, a common predictable book, “I see the animals,” may read, “I see the horse. I see the sheep. I see the cow. I see the animals!”
An objective this teacher has for the students may be for the them to make meaning from the printed words. Actually, the exposure to rich content, syntax, and vocabulary that young students need could be coming from teacher read alouds. The decoding instruction kids at this stage need should instead focus on the simple letter-sound correspondences they have been explicitly taught (phonics).
Given predictable texts, some children, who have good phonemic awareness skills and letter-sound correspondences already, may implicitly pick up on patterns within the English orthography (written language system) on their own while they read these predictable books; they may teach themselves to read (see Share’s self-teaching hypothesis). Other children, who enter school with underdeveloped phonemic awareness skills, will just fall further and further behind in these systems.
With predictable texts, the teacher is actually teaching the child the English orthography must be either memorized (hello, “sight words!”—another post for another day) or guessed based on the context and the first letter(s). With predictable texts, the teacher is implicitly teaching the child the English orthography is *unpredictable.*
However, in reality, we want children to learn that English is an orthography that can be decoded, or sounded out. Although it is a deep, opaque orthography, it is highly regular. We can systematically instruct students in:
- letter-sound correspondences (i.e., how graphemes, or groups of letters that make one sound—ch, dge, igh, f—relate to phonemes, or the smallest sound that makes a difference in the word’s meaning—/ch/, /k/, /sh/; /j/; /ī/; /f/),
- phonics patterns (the bossy e that makes the vowel long, as in hike or brave, or using “tch” after a single, short vowel, as in hatch or pitch),
- phonetically irregular words, specifically pointing out which part of the word is phonetically irregular (s[ai]d, t[w]o, [o]nce)
- syllable types and division strategies (open syllable—the vowel is long—he, go, [pi]lot, or closed syllable—the vowel is short—cat, flop, [bub]ble, among others),
- morphology (the smallest units of meaning within a word—construct, structure, instruction), and
- etymology (how words originate, change, and relate to each other—twice, two, twin).
We can teach these skills and principles explicitly to all children—the photo below was from a couple of advanced students in a PreK classroom. It is helpful to all, harmful to none, and essential for some.
That is why it is so important to understand the Simple View before choosing an intervention… is the child struggling with the code (D), is the child struggling with the language (LC), or both? And why it is important to ensure a strong Tier 1 (general education) curriculum that includes explicitly teaching the printed code to build students’ decoding skills and includes rich content knowledge, vocabulary, and syntax to build students’ language skills.
Hollis Scarborough’s Reading Rope (2001) gives us more insight into the complex ideas the Simple View of Reading seamlessly represents. In the image below, the top (red) strands represent a student’s language comprehension (LC) development. The bottom (blue) strands represent the components within a student’s word recognition development (D).
As the student’s word recognition becomes increasingly automatic and language comprehension becomes increasingly strategic, skilled reading emerges.
Considering the typical deficit of a student with word-level reading difficulties lies in phonemic awareness skills, this graphic may shed light on the many components playing a role in reading the words on the page. Students with significant difficulties in word-level reading skills despite adequate instruction may have dyslexia (a specific learning disability in basic reading skills).
Students might also be able “break the code” and pronounce all of the words on the page, but have trouble understanding what they are reading. These students may have deficits in syntax (grammar), vocabulary, or content knowledge. Students who have significant difficulties with language comprehension despite adequate instruction may have DLD (Developmental Language Disorder).
All of these skills exist on a continuum, as shown in the graph above. Understanding the complexities of the Simple View of Reading can help us organize our thinking and may lead to more valid assessments, targeted lessons, and intensified interventions.
