Have the student read a page of material out loud. Select a passage that is easy enough for her to accomplish --- something below the normal reading level of her age group. This will help you place her at the appropriate reading level and see her strengths as well as weaknesses. Listen for stuttering, awkward pauses or instances where she is having difficulty pronouncing a word. Make note of these instances so you have a measurable starting point.
Go back and read the passage out loud to the student. Use your finger to point along the page for her to read what you are saying. This will help her pair the letters along with the sounds of each word. It is important to have her repeat after you at any instance you had noted where she was having difficulty. This is a vital part to the learning process.
Have the student write out any words she had difficulty pronouncing or understanding. This will become her personalized vocabulary list. For the fluent speaker this list may be short. However, the non-fluent speaker will have a lot to gain from this method of learning. While it may be a long and grueling process to get through the entire passage --- depending on its length --- the student will ultimately be able to fluently speak the article and understand the words thoroughly. This will help her in comprehension stages and other activities she may have to do with the reading in the future.
