The one area I've continued to see is on text complexity. Students are expected to be working with texts at much deeper levels than their current reading level. They should be talking about and exploring texts to build their skills. With scaffolding, students are able to build their skills that are needed to comprehend and decode these texts.
With my RtI students, I'm trying to work to bridge that gap with them. One thing I've found with my students is that they don't often understand the questions that are being asked of them. Or, alternatively, they don't answer the questions that are being asked of them. We spend many hours working on dissecting the questions and framing their answers so they are better able to demonstrate that they know what they're reading. One strategy I use with my students is PQA.
