The term 'best practice' is used to describe whatever works in a given situation or environment. So, it includes the maximum that can be imparted to the students by the teachers and the way teachers deal with the students. It is nothing but cashing whatever resources you have and generating the best possible output. Let us see some of the practices.
Through Evaluation, the children come to know where exactly have they erred, where they are good, and which are the areas they need to improve upon. A good comment from the teacher can boost their confidence.

Spoon feeding should be completely avoided, if students have to be inculcated with challenging and rigorous learning. To involve them actively in the educational system, inquiry, assessments, and in-depth learning will be really helpful.
Out of time
Effective management of time and accommodating a spectrum of the interests of students, teaching and non-teaching staff, is what top educational institutes are structured for. All the stakeholders viz., students, teachers, and parents should be addressed regularly, so that all are in sync and that eventually helps children learn more effectively.
The mentioned practices are generic and are not specific to a particular institution or a group of institutions. Ultimately, it all boils down to what suits the best to a specific institution.
