It's amazingly controversial. Yet the nature and process of reading are well-understood. This controversy is crazy. I don't hear carpenters arguing this way. Clearly all of these tools, and more, are required to build a decent house.
Literacy is at least as complex as carpentry.
The truth is, all readers need ALL the tools, if at all possible. Reading is complex . Decoding is not all of reading. Check out a simplified diagram to see a more 'whole' view of spoken language and reading. Even perfect naming of every word by sight does not explain fluent reading.
