I usually follow hierarchy approach to train.
Depending on the basic knowledge student have i make my sessions
I usually start with basics brush ups then moving forward to professional achievements .
I usually prefer recording sessions too for the future reference of students
Along with some tutorial tasks for the better understanding of concepts
I usually breakdown the complete tutorial into hierarchical small tasks which ultimately brings confidence in student and sense of achievement
I also prefer some reward system which helps students to participate more in session and make the session more lively

Faq is the best way to solve all the miscellaneous queries from the students.
This ultimately helps in going more deeper into the topics and clarity of subjects being taught
