I don't have kids - but I have a family member with Alzheimer's Disease at home. This can bring interesting subjects up during our classroom discussions of older adults, and the disease itself. One thing to remember, no matter what the subject in class, get enough people in class and someone will either have, or have a family member who has it. I like to hear how my fellow students handle their problems and issues with different conditions. The one thing I try to remember in nursing school
is that these are patients, human beings with these conditions, not just a diagnosis and pathophysiology. And yes, even their families are our patients. Try to be patient with some of your fellow students.
On the other hand that if you are talking through the lecture, giggling like a middle schooler or just being disruptive just stop it. I don't have time to try to shut you down, my lecture moves too fast, school moves too fast for me to spend my time shushing those who are being childish.
