We will break at 11:30 to give you time to get a lunch if needed. At 12:00 noon Kelli Gamez-Warble has a 1-hour presentation on Step Up 4 Women.

About the presentation:

Attendees will engage in a Careers in Physics lesson in student mode and debrief in teacher mode as in any typical modeling workshop. (In my opinion, this lesson is usable right now in any high school physics class and a great way to get students thinking about their college and career goals through the lens of physics. Those who attend can receive the materials.)

 

They will then be given an overview of the research behind the lesson and of the other lesson plan to be available from STEP UP 4 Women (on Discussing Underrepresentation and unconscious biases--again through a physics lens.)

 

Note these materials are NOT YET publically available. AMTA is getting access to pilot materials as the STEP UP 4 Women team decides the best way to launch the national initiative (set for January 2019). And only a few AMTA sites will see materials now (ASU and the Ohio Conference attendees.)
