It was enlightning all this information and how we have students suffering PTSD disorder. It helped a lot all the techniques I learned today. I will be implementing the techniques in my classes. 

I will apply the new knowledge creating short lectures and adding activities during class. 

I love to hear the Harvard Professor saying please know your students and do not humilate your students. It is very important to be aware of our teaching methods if the method helps the student feel safe and welcome or are we belittling our students. This is very important to have a full group of students connected and motivated with the course and instructor.
