Reading comprehension is defined as the level of understanding of a writing. For normal reading rates (around 200-220 words per minute) an acceptable level of comprehension is above 75%.Fact: date=January 2008

Proficient reading comprehension depends on the ability to recognize words quickly and effortlessly. If word recognition is difficult, students use too much of their processing capacity to read individual words, which interferes with their ability to comprehend what is read.

Many educators in the USA believe that children need to learn to analyze text (comprehend it) even before they can read it on their own, and comprehension instruction generally begins in pre-Kindergarten or Kindergarten. But other US educators consider this reading approach to be completely backward for very young children, arguing that the children must learn how to decode the words in a story through phonics before they can analyze the story itself.

During the last century comprehension lessons usually comprised students answering teachers' questions, writing responses to questions on their own, or both. The whole group version of this practice also often included "round robin reading," wherein teachers called on individual students to read a portion of the text (and sometimes following a set order). In the last quarter of the 20th century, evidence accumulated that the read-test methods assessed comprehension more than they taught it. The associated practice of "round robin" reading has also been questioned and eliminated by many educators.

Instead of using the prior read-test method, research studies have concluded that there are much more effective ways to teach comprehension. Much work has been done in the area of teaching novice readers a bank of "reading strategies," or tools to interpret and analyze text. There is not a definitive set of strategies, but common ones include summarizing what you have read, monitoring your reading to make sure it is still making sense, and analyzing the structure of the text (e.g., the use of headings in science text). Some programs teach students how to self monitor whether they are understanding and provide students with tools for fixing comprehension problems.

Instruction in comprehension strategy use often involves the gradual release of responsibility, wherein teachers initially explain and model strategies. Over time, they give students more and more responsibility for using the strategies until they can use them independently. This technique is generally associated with the idea of self-regulation and reflects social cognitive theory, originally conceptualized by Albert Bandura.

Teaching reading comprehension

The U.S. National Reading Panel conducted a comprehensive literature search on teaching reading comprehension. They concluded that (1) vocabulary knowledge, (2) reading comprehension instruction based on reading strategies, and (3) teacher professional development on effective comprehension practices were critical to effective reading comprehension teaching.
