Hi Oriole,
Something that might work in your setting that I have used is a structured outline over the text content. I assign a chapter or portion of a chapter for the next class. I give the students a structured outline that I want them to complete before the next class meeting. I give the professional points for completing the outline. What the structured outline is a list of the key points that I want the students to pick up on. Under each key point are some questions or sentences with blanks for words. The students go into the chapter find the high point and then abstract out the needed information contained in that main point section. This format helps them to get through the material quicker, forces them to concentrate on select points and by writing down the information increases their retention of the information. This greatly reduces reading time but greatly increases their content knowledge. The professional points give them a reason for completing the work.
Any questions on this let me know.
