What Causes Poor Reading Comprehension & How Do We Fix It?  

by Ellen Doman

This is a question we hear from many parents. Some children have poor reading skills both in identifying words and comprehending the text, but many children are good readers, meaning good at word identification and able to read quickly, but lack comprehension. So, let’s look at what’s going on and how NACD addresses those issues and can help prevent those issues from developing. 

Reading comprehension can be broken down into two types of comprehension. There is a type needed to understand how one sentence links to another sentence. The sentences may link because pronouns were used in the second sentence to replace the proper nouns or common nouns in the first sentence. They may be linked by the relationship of two actions or two objects being identified. For example, Tommy woke up. He knew he needed to hurry. The relationship between these actions implies that Tommy is waking up in his bed and has someplace he needs to go, perhaps school. Another example would be: Tommy got his sneakers on quickly. Then he grabbed his basketball. As we read these sentences, our understanding of the vocabulary and the relationship of these words to each other starts to give us a construct for what may happen next. 

What happens when there is a word that is not understood in the sentence? Tommy awakened. He was anxious about being on time. Is there a construct of what is happening if you don’t understand a word in the first sentence? No, there is not. Let’s look at the next example. Tommy put on his galoshes as fast as he could. Then he grabbed his poncho.  Do we assume that a child will have a construct of what is happening here? Without an understanding of those key nouns, we can assume that they do not. 

So, we can see that receptive vocabulary and the relationship between words is important for that immediate “internal” comprehension of a text. 

What impacts on comprehension of a larger text? Working Memory is needed to provide a framework and hold the pieces so that a larger text, more than a few sentences, can be understood and recalled. If the text or story contains vocabulary largely understood by the child, then it is the working memory that is going to build the larger construct to hold and keep sorted all the information, sequentially and in a way that permits recall and understanding. A strong working memory is able to establish and hold the big picture while aligning the details of the narrative sequentially.

There is one more factor that impacts on comprehension in addition to vocabulary and working memory and that is sustained attention to language. If there is a break in attention to meaning as the individual is reading due to the habit of reading too quickly or due to the habit of disengaging from language too rapidly, comprehension is quickly lost. If this happens to adults or older students, they will typically realize and go back and re-read the portion that they missed. With children and some adults, however, this is not the case. So, we need a strong habit of sustaining attention to language established by strong short-term auditory memory.

Let’s look at these pieces as they relate to how NACD addresses neurological development in order. We work early on to develop a strong understanding of receptive language and word meanings and functions. We work early and continuously on building strong short-term and working memory auditorily as well as visually. We have diverse activities to address sustained and accurate auditory attention. We read to children and use audiobooks because studies have supported that listening comprehension and reading comprehension use the same neurological mechanisms. We use conceptual memory activities to work the mechanisms needed to group random words logically and to see new associations between seemingly random words. 

Reading comprehension is not just a matter of the right reading materials, the right workbook or curriculum. Reading comprehension is based on the very neurological functions that we address with our programs.

The following research article among many others, supports the findings of NACD over the decades that we have been working with children and adults on these issues.
