Reading Comprehension Depends on Content Knowledge

Michael Zwaagstra:

Walk into an elementary school classroom and you will probably see a lot of books on the shelf. Take a closer look and you will often find a coloured dot, a number, or a letter on each book’s spine. Those dots, numbers, and letters show the reading level of each book.

Books are assigned these levels so students choose books that will challenge them without being too difficult for them. Instead of having the entire class read the same book, students pick books from their designated reading levels. Levelled libraries make it possible for students to find the best books to read. At least that is the theory, but the reality may be somewhat different.

In order for students to read a text effectively they must be able to do two things—decode the individual words and comprehend the sentences and paragraphs. Too often we focus on how students decode words (the ongoing phonics vs. whole language debate), but in that debate we neglect the importance of reading comprehension. A student may be able to “read” every word on a page and yet not understand what the text actually means.

I used to be an elementary school teacher so I remember doing running records with my students to assess their reading levels. However, it didn’t take long before I noticed that my students performed much better on the comprehension questions after reading an article about a sports game than after reading an article about Dr. Norman Bethune, the Canadian medical doctor who went to China in the early twentieth century, even though both articles were officially at the same reading level. The question is “Why?”
