Dr. Victor Sampson

Creator of Argument-Driven Inquiry

Dr. Sampson developed the Argument-Driven Inquiry instructional model and co-authored the ADI book series. He leads this institute himself, so participants are not learning a secondhand version of the model. They can ask the person who designed it why each move works and how to adapt it for their own teachers.

What you take with you

You leave ready to run the workshop, not to build it

Every participant leaves with access to the ADI certified trainer folder and the full set of facilitator materials for the Introduction to ADI workshop. You are delivering the same workshop you just experienced, with the same slides and the same resources, edited to fit your teachers.

The workshop slide deck

The complete Introduction to ADI presentation, fully editable, so you can drop in your own examples, campus names, and pacing.

Facilitator notes

Timing, talking points, and the facilitation moves behind each segment, so you can lead it with confidence the first time.

Participant handouts

The handouts and investigation materials your teachers will use during the workshop, ready to print and copy as often as you need them.

An ADI book

Choose your title during registration and pick it up at sign-in.

The certified trainer folder Everything lives in the ADI certified trainer folder. Completing the institute gives you access to it, so the current version of every slide deck, facilitator note, and handout is always where you left it. EDIT: confirm whether use is limited to workshops inside your own district.
