Reading comprehension includes all of the processes related to deriving meaning from written language (including books and other forms of written language) and constructing meaning from written language. “Deriving meaning” indicates that there is meaning in texts and that meaning needs to be understood. “Constructing meaning” indicates that often readers go beyond the meaning explicitly contained in the text and add to that meaning based on their own experience and their ability to infer additional or deeper meaning. Thus reading comprehension is much more than the ability to read individual words and know what those words mean. To comprehend what one reads is to understand the meaningful message sent by the author.
