I directed Challenge 4 this year, and one of the last events of this year was the Senior Thesis Presentation and Defense.
My three students, including my oldest daughter, wrote twenty page thesis papers on topics of their choosing including:
Christian Education and the Public Schools
Masks Mandates Were a Mistake
Modern Dating is Ineffective
Then they had to share their papers with a panel of judges two weeks ahead of time and then stand and present an abstract of their paper to an audience and answers challenges from a panel of judges for thirty minutes.
They all did a great job!
It was a rewarding culmination of several years of the rhetoric, logic, debate, composition, research, and public speaking they have done through the Classical Conversations Challenge programs.
