Are you asking about formal programs like Reading Recovery? If so, Google terms: Marie Clay or Reading Recovery.
If you are talking about focusing on one student who is having a difficult time in learning to read, I think you have to find a way to work with this child 1:1, for a few minutes each day. It needs to be daily so the child gets enough feedback on what he/she is doing to know what strategies to continue/eliminate. Novice readers have very little understanding about what works well and what does not when attempting to break the print code. They often develop unique and unproductive guesses about how it all works. Many times they actually think they have to know all the words there are to be able to read. Imagine if that were true how few of us would be readers!
