Firstly, my students and I always come up with a concrete goal for the next lesson at the end of each lesson. Then, I tell my students that the first thing they should do after lesson is to come up with a daily plan for the week to reach that goal.....

This article explains it pretty well.
I like what you wrote (the whole post) but I don't like the article, especially its examples. "Play p. 1, no mistakes, at 150 bpm" is no kind of goal, and does not go into how to practice. It's an "end goal". So will the student play p. 1 from beginning to end slowly and faster, over and over? Is he just aiming for the correct notes in "no mistakes"? What about relaxed and good motion? In "how to practice" I'd expect to see things like working in smaller sections, and bringing them together; aiming for areas of difficulty and how to tackle them (as instructed in lessons); aiming for timing, or counting, or dynamics.
I like the idea of concrete goals, guidance in practising, and also using a variety of resources including modern ones.
You have mentioned this app in several of your posts. One cannot see samples without signing up, and one must be a practising teacher in order to sign up. In apps I've seen in the past, they did not allow for much detail, and they tended to go toward either keeping track of practise time, or frequency (how often to repeat something). I sort of prefer pencil and paper (no notebook dumping for me.
