Honoring Our Own PhET K12 Specialist: Teacher Trish Loeblein


Congratulations to Conifer Chemistry Teacher and PhET K12 Specialist, Trish Loeblein, on her retirement from teaching!

Trish has been a dedicated teacher for over 30 years, and a member of the PhET team for the last 10, helping design over 50 simulations and contributing over 130 guided-inquiry-based activities along with many teacher resources! Her activities are the most popular in our database with more than 900,000 downloads in the past year. In addition, she has run numerous teacher workshops and webinars, both locally and nationally. Over her many years of teaching, Trish has touched thousands of students focusing on their learning, specifically understanding and learning to think, NOT just memorization.

Thanks Trish for inspiring a generation of students! And while the students will certainly miss you in the classroom, we are excited that you will continue to work part-time with PhET! #ThankaTeacher

#ThankaTeacher Week: Thanks to Martin Veillette

In honor of #ThankaTeacher week, PhET would like to thank Prof. Martin Veillette. Martin comes to us from Berea College where he is an associate professor of physics, teaching courses across the physics curriculum, from astronomy to quantum mechanics. He has been an avid user of PhET simulations as an instructor and this year he has been with us working as a software developer, learning the tools of the trade during his sabbatical leave. During his time at PhET, he partnered with Amanda McGarry to create the brand new #HTML5 sim Least Squares Regression. He also worked on the upcoming #HTML5 Charges and Fields and Pinko Probability.  When he’s not teaching physics, you can see him in “creeking” in the streams of Kentucky. Thanks Martin!

Meet PhET Team Member Yuen-ying Carpenter

Yuen-ying Carpenter

Meet Yuen-ying Carpenter who came to the PhET team with a PhD in chemistry, and an avid interest in investigating how college students learn in both core chemistry classes and in applied disciplines such as the energy sciences.

She brings with her both inquiry-based college curriculum development expertise from her time at the University of Calgary and Dalhousie University, as well as a taste for in informal science inquiry and outreach for all ages from the Calgary science centre, TELUS Spark.

When she’s not at PhET, Yuen-ying can be found biking around Boulder, or hanging out on a trapeze somewhere 10 ft in the air.
