Harkness help

During this year's summer program, I will teach three literature courses--one course per grade level. We have rising seventh, rising eighth, and rising ninth graders. The course is designed to promote healthy discussion and dialogue concerning each text. With the emphasis on discussion, I've decided to research the Harkness method used by many independent schools, but made famous by Phillips Exeter Academy.
I have found some resources to help guide my preparation, but have yet to come across a video showing the method in action. As a visual learner, I hope to find something to watch that goes beyond telling about the method.
I am excited to begin, especially considering some of the texts I get to teach:
A Prayer for Owen Meany
Lord of the Flies
A Separate Peace
The Chosen
The Old Man and the Sea
"The Necklace"
"This is What it Means to Say Phoenix, Arizona"
"A Good Man is Hard to Find"
"The Most Dangerous Games"

There are many more short stories as well as the text, How to Read Literature Like a Professor. I feel energized, reinvigorated.
