I admire your honesty in giving feedback that you try to give it a careful thought before actually saying it all aloud to the student. Seeking advise from mentors and colleagues is a good way of doing it and practicing it correctly. I agree with you that you have to commend even the small wins of the student to be able to motivate them in their practice and build confidence in the performance of task. The value that you place in communication would surely place you in a better position to deliver feedback to your students. Surely you and your students would achieve the learning outcomes of the course your are teaching---sa inyong pagSAKSES sa pagtuturo at pagbibigay ng feedback!
