Basically whenever I starts teaching I prefer to know the potential of the student. What they think , what they know is very important thing. So after concluding the things while talking i short out some stuffs like what I need to focus and how ?
After that when the classes get done i always prefer to check whether the student were able to understand the topic or not then after only i go further.
I always suggest the student like always get ready to ask a question i am here for you to answer. After my teaching experience i learned that some times student were not saying things what they dont understand to as a hidden trick i always stay alert during practical session to know that weak points of each and every student
