A great set of cliff notes/summary is located here. These are great practices for all students, particularly ELL's, and also particularly for students who may struggle with academic language, even if they are not ELL's. Where I work there are many students who are ELL's (about 30%), as well as many who just have very low reading/writing/language skills, although they are native speakers. These strategies are helpful to all of them!!!
The one I found the most interesting is the need to have a specific content objective and language objective for each lesson.
