Sure. You can do Groups Forward or Groups Backwards. Pick a point, it could be a few beats long or a few measures long. Practice the 1st group at least 5 times, slowly, getting everything correct. Go to the next logical group and practice 5X, getting everything correct. Then practice both groups together 5X; move on to group 3, 5X; then practice group 1-2-3 5x, always practicing slowly for everything correct. Don't count any incorrect repetitions.It is pretty much the same as chain. I think Groups Backwards (last 2m, then last 4m, etc. of the piece) is especially effective, to prevent learning the beginning much better than the ending.
Fun Repeats - Kind of a joke to my students - A teacher in our area says "From now on there will be no more drills. They are fun repeats."
Fracture practice came from a book by Charles Cooke, which we referred to as the "Cookbook" in college. A fracture is much like a group, only in fracture practice you must practice a little before + a little after. 5X is my usual rule, but it could be 10X or 20X. So practice the middle group first, the fracture, then move a little before + a little after the fracture, then further before + further after the fracture, like this: ( ( (Fracture) ) ) The goal is to work the fracture (the most difficult part) into what is easier, until you can fit it into the whole context of the section or piece.
