These pictures are not worth a thousand words
In addition to judging primary reading books by their covers, most educators also judge them by the quality of their illustrations. The dominant education philosophy esteems gorgeous books with eye-catching pictures and beautiful colours. This means, of course, that kids’ reading material tends to be fiendishly expensive. It also means that scant attention is paid to how effective the books are in terms of teaching kids to read. And there is a third problem, not widely known.
The presence of illustrations in kids’ beginning reading material is actively harmful in terms of helping them become good readers. You can read all about it here (h/t to Alvaro Fidel Martinez).
Beginning readers are frequently encouraged to guess at unknown words on the basis of various clues such as those provided by the story’s pictures. This encourages two bad habits all at once. The first bad habit is the guessing itself, a practice that is bad for two reasons: first, sometimes the kids guess wrong, with monster hits to comprehension; and second, the kids’ decoding skills remain undeveloped. The other bad habit inculcated by guessing words on the basis of the pictures is that this practice interrupts the smooth progression of the reader’s eye movements across the page. When kids lose their place in the sentence because their eyes are jumping to the picture(s) all the time, it is typically hard for them to get back to where they were in the sentence and, in some cases, to remember what they had read before.
The goal is for beginning readers to read as smoothly and continuously from left to right as possible - just as accomplished readers do. The presence of illustrations on the page militates against this.




Even worse for children who begin with weakened language skills, which include students that are of the low income. For the would be LD students, the costs to unlearn and reteach reading costs school boards a pretty penny that may or may not be effective, as well as the LD students paying the price of having low literacy and numeracy skills.
