Spring 2016 Section Report

AAPT Section Report 2016

Brian A Pyper, Section Representative

 

The Idaho-Utah Section of the American Association of Physics Teachers met April 15-16 at Idaho State University in Pocatello, hosted by local organizer and Section vice president Steve Shropshire. The meeting combined with an SPS Zone 15 meeting as well. About 70 people were in attendance for the meeting, which featured a banquet dinner, several guest speakers, and the perennially popular demo show (http://www.physics.isu.edu/events/conference/AAPTDemoSchedule.shtml) and make and take.

The program was excellent, with a varied collection of contributed talks and posters. The full program of events is available at http://www.physics.isu.edu/events/conference/schedule.shtml.

The business meeting Saturday re-elected Adam Beehler from the University of Utah as the section treasurer, and tentatively elected Matt Zachreson of BYUI to serve as president elect, and host the meeting in Rexburg in 2018 on the condition that Boise State, whose turn it should be, can’t do it, and that his one-year appointment at BYUI is renewed.

So the Current slate of officers for the section is as follows:

Matt Zachreson (BYUI) – President Elect (rotates to Vice President in 2017)

Adam Beehler (UofU) – Vice President and Treasurer (2017)

Steve Shropshire (ISU) – President (2017)

Larry Smith (Snow) – Past President (2017)

Brian Pyper (BYUI) – Section Representative (term expires in 2018)

 

A sincere thanks to Steve Shropshire and the department at ISU for hosting the section so well. Keep abreast of the section doings and plans for the Spring 2017 section meeting at the University of Utah on the section’s web page at idahoutah.aaptsections.org.

2016 Spring Section Meeting Announcement

Dear Colleagues,

 

The 2016 meeting of the Idaho/Utah Section of the AAPT will be at ISU in Pocatello, Idaho, April 15 – 16.  Of all of the possible dates I proposed in emails to section members and others since October, this weekend had the fewest conflicts according to replies I received.

Please reserve this date and plan to attend, if convenient.  We will have our usual Friday evening demo show, which will be open to the public.  For Saturday we will have contributed talks, student posters, our annual section business meeting, a raffle, an optional tour of the Idaho Accelerator Center, and a leaf-blower hovercraft construction workshop.  Our meeting will be joint with a meeting of Zone 15 of the Society of Physics Students.

 

Additional details regarding registration, abstract submission, lodging, and a conference website will follow in the next few weeks.  If you are aware of any high school or college physics teacher who is not in recipient list for this email, or anyone else you think may have an interest in attending our meeting, please forward this to them and cc me.

 

Thank you for your time and consideration, and have a great semester.

AAPT Idaho-Utah Section report spring 2015

AAPTID-UTSpring2015MeetingThe annual meeting of the Idaho-Utah section of the American Association of Physics Teachers was held March 13-14 at Snow College in Ephraim, Utah. The ever-popular demonstration show was held Friday night and was attended by over 200 people.  A short video compilation (thanks to Snow College!) is available here: https://snow.mediaspace.kaltura.com/media/aapt_event/0_9sg0w43a/13823862

 

Saturday held a full season of talks and activities, highlighted by a report from the Governor of Utah’s advisor for science education, Tami Pyfer. About 50 people participated in the conference, which was organized by Larry Smith, the current vice-president of the section, who did a fantastic job. A copy of the program is attached below.

 

Of particular interest was the business meeting, in which Brian Pyper was re-elected as Section Representative and Adam Beehler was elected as president-elect in absentia and in anticipation of his organizing the section meeting in two years at the University of Utah. This means the current spate of officers is: Katie Devine (CofI) – Past President, Larry Smith (Snow College) – President, Steve Shropshire (ISU) – Vice President, Adam Beehler (UofU) – President-Elect and Treasurer, and Brian Pyper (BYUI) – Section Representative. The section meeting will be held in Pocatello next year hosted by Steve Shropshire.

 

Rondo Jefferies from Weber State graciously sent me a note listing the history of the section meetings going back to 1983 when the section was founded. I’ve posted it below.

Two items:

The National AAPT winter meeting in Orlando is up for registration. see http://www.aapt.org/Conferences/wm2014/

Also: Beth Cunningham from the National Office sent me this today. Shout if you’re interested.

“I am seeking your assistance in finding an AAPT national member in your section to represent AAPT at an upcoming important conference in the region of your section.  The Conferences for Undergraduate Women in Physics (CUWIP) are three-day regional conferences for undergraduate physics majors.   The goal of the conferences is to help undergraduate women continue in physics by providing them with the opportunity to experience a professional conference, information about graduate school and professions in physics, and access to other women in physics at all career stages with whom they can share experiences, advice, and ideas.  The program includes research talks by faculty, panel discussions about graduate school and careers in physics, presentations and discussions about women in physics, laboratory tours, student research talks, and opportunities for students to interact.

The conferences are held simultaneously at eight different institutions of higher education.  The 2014 conferences will run Friday evening, January 17th, through Sunday afternoon, January 19th.  For more information about the conferences, see http://www.aps.org/programs/women/workshops/cuwip.cfm.  One of the locations for the conferences is University of Utah which is located in the Idaho-Utah section.  I need your assistance in finding a local AAPT national member who could represent AAPT and provide materials about careers in physics particularly involving teaching in high school or at the college or university level.  In addition, this representative can provide information about AAPT and the value of an AAPT membership in supporting careers in physics teaching.  The national AAPT office can provide materials for this representative to distribute.  If needed, we may be able to provide modest travel reimbursement if the volunteer requests support.

 

The leadership of AAPT understands the value of increasing the participation of women in physics careers.  AAPT’s current leadership includes four women: the current president, vice president, past president, and executive officer.  We are also keen to support programs to increase the number of women in physics, particularly as role models and mentors teaching physics to the next generation of scientists and citizens.  In fact, the AAPT Marketing Manager RaShonda Rosier (rrosier@aapt.org) is attending the conference at Florida State University and I am attending the conference at University of Maryland.

 

Can you find a local AAPT member who is willing to attend this conference as a representative of AAPT?  And, can you connect that individual to RaShonda and me by forwarding their contact information?  I would appreciate this information by October 31st so that RaShonda and I can coordinate registration and mailing of materials with this individual.  We can also assist this individual in contacting the conference local organizing committee.  As always, I appreciate your willingness to assist AAPT!

Warm regards,

Beth”

I told her I’d do it if no one else wanted to.

Thanks,
