You are paying a lot of money for this course.
1. Your instructor should not be spending too much time doing other things, you need as much continuity as possible.
2. It is the correct end result you need to achieve, the wording does not have to be exactly the same as your instructor but it needs to be similar and in the same sequence.
3. If you are not happy with your instructor you need to take these issues up with him. Your evidence of lack of praise is the hallmark of a poor instructor unless you are not doing very well but even then encouragement is the alternative tool coupled with a bit of 'false' praise.
It is important to be comfortable and satisfied with the instruction you are receiving so do something about it, if no luck with the instructor talk to the CFI.
The upside of this is that you are learning how not to treat your own students--stick with it and good luck
