Kareem, great technique and not used enough within our sector of higher education so great job. There are many ways to educate and transfer knowledge and the best ways use positive energy versus negative. Dr. Joe Pace from The Pacific Institute teaches us that it takes 11 positive statements to make up for a single negative one which shows how powerful and destructive negative energy can be to a student's self-esteem. By finding positive ways to assist students in their full understanding of a subject you help to continually build their confidence, trust and excitement about learning. Thanks for sharing and keep up the great work. James Jackson
