Research on Reading Intervention for Low-Literate Adult ESL Learners

I just read a research report on the impact of a reading intervention for low-literate adult ESL learners. A link to the research report can be found here. Reactions? For me, these findings illustrate the need for the development of more low-level materials with a systematic, sequential sequence of skills that students can transfer to reading at their appropriate levels. It also suggests a need to train teachers on how to appropriately teach students these strategies and skills. I'm working on it! A free resource currently available includes the Online Workshop which orients teachers to basic decoding and spelling skills that they can apply in their classrooms.
