Hello Farangis. I mainly use the idea of the 'feedback sandwich' - ie Praise for a positive element of the response in relation to the assessment criteria; then areas for development or things that I would have liked to seen further developed; and then also finish on a positive e.g. specific encouragement for the next assignment. I teach teachers and in the context of working with primary children, the idea of the feedback sandwich has been compressed into the catchy 'Two Stars and a Wish'! A popular characterisation here:

A couple of academic references:

Hattie J, Timperley H. (2007) The power of feedback.  Review of Educational Research, 77 (1), 81-112

Hohrenwend, A. (2002). Serving up the feedback sandwich. Family Practice Management. 9, 43-6.

It is important that 'correctional feedback' be consistent with the assessment criteria and any rubric provided to students.

Regards.

I prefer explicit corrective feedback technique. Usually when students make mistakes I often tend to immediately correct them. Otherwise, students will continue making the same errors continuously and those errors will fossilize or will remain forever.
