Traditional phonics based learning stems from a behaviorism approach to learning, often associated with B.F. Skinner's work. The basic idea is that students learn how to break down and sound out words in order to learn how to read. The pros of phonics include better spelling, pronunciation, and recognition (as some studies have even shown), as well as providing a concrete method for students to use any time they encounter a complex, difficult word. Once a child learns the basics and how to put words together, they can virtually read just about anything. Cons, however, include some children having difficulty understanding the meaning behind what they are reading. What good is it if they can read but cannot understand? Also, consider that almost half the words in the English language are not pronounced how they would be if strictly using phonetic rules.
A more constructivism based approach, based on the ideas of Lev Vygotsky, points toward whole language literacy learning as the way to go. This method emphasizes meaning rather than correct spelling or pronunciation. Students learn words by connecting them to previous knowledge, other words they already know, and to their own personal lives and backgrounds. Some pros to this method include better understanding of language, and a more meaningful approach to learning to read. The cons include a lack of structure (more so dependent upon the teacher), and a decline in accuracy when reading and spelling.
Overall, I believe the best way to teach is to use a bit of both theories. There really is no black or white in the education world. Students learn in an infinitely diverse number of ways, and therefore it is important not to get stuck on one specific method of instruction. As mentioned in the second article I read, visual learners may do better with the whole language approach, where as auditory learners may feel more comfortable with phonics. I think this is a very valid point, illustrating the importance of combining both methods. Personally, I think the best method would be to use phonics in the very first steps of learning to read, and then slowly integrate whole language concepts.

Retrieved 26, 2009.This website provides background information on the controversy over phonics based and whole language literacy. It includes references to studies that have been done and many other references on the topic. The information seems to be unbiased and gives the pros and cons of each viewpoint. Also, it was written in 2008, so the material should be more current than most other websites.

This website provides a brief overview of the two arguments. Very easy, understandable, and quick read that gives a good understanding of both points of view. The website, however, is outdated and does not provide any references fro the information presented on the page.
